  • json_encode with mysql content and umlauts in utf-8

    - by i3rutus
    Hey, i feel my beard growing while trying to find out the Problem here. Basic the Problem is, that Umlauts/Special Signs äöß ... don't work. I guess everyone is sick and tired of that questions but all the solutions found online don't seem to work. Im having utf-8 content in a utf-8 Mysql Database. I feel the Problem ist somewhere in the Database connection but i just can't figure out. character_set_client utf8 character_set_connection utf8 character_set_database utf8 character_set_filesystem binary character_set_results utf8 character_set_server latin1 character_set_system utf8 Im not sure if the problem is the latin1 for character_set_server because im not into that mysql stuff. I also dont know how to change cause i can't access the mysql server's config files. Whatever is confusing me, that if i get my results from the Database and echo it, print_r gives the right result. ini_set('default_charset','utf-8'); header('Content-Type: text/plain; > charset=utf-8'); Firefox says char encode is utf-8 but if when i output: print_r($listnew); echo json_encode($listnew[5]); print_r results everything right but json_encode does wrong. print_r: [5] => Array ( [id] => 5 [data] => U-Bahnhof Theresienstraße [size] => 17 ) json_encode: {"id":5,"data":"U-Bahnhof Theresienstra\u00dfe","size":17} i know json_encode needs a utf-8 string to work properly there and i feel im having a encode trouble here but i just can't firgure out where it is. Any help would be appreciated, thanks in advance. i3

  • Implementation review for a MVC.NET app with custom membership

    - by mrjoltcola
    I'd like to hear if anyone sees any problems with how I implemented the security in this Oracle based MVC.NET app, either security issues, concurrency issues or scalability issues. First, I implemented a CustomOracleMembershipProvider to handle the database interface to the membership store. I implemented a custom Principal named User which implements IPrincipal, and it has a hashtable of Roles. I also created a separate class named AuthCache which has a simple cache for User objects. Its purpose is simple to avoid return trips to the database, while decoupling the caching from either the web layer or the data layer. (So I can share the cache between MVC.NET, WCF, etc.) The MVC.NET stock MembershipService uses the CustomOracleMembershipProvider (configured in web.config), and both MembershipService and FormsService share access to the singleton AuthCache. My AccountController.LogOn() method: 1) Validates the user via the MembershipService.Validate() method, also loads the roles into the User.Roles container and then caches the User in AuthCache. 2) Signs the user into the Web context via FormsService.SignIn() which accesses the AuthCache (not the database) to get the User, sets HttpContext.Current.User to the cached User Principal. In global.asax.cs, Application_AuthenticateRequest() is implemented. It decrypts the FormsAuthenticationTicket, accesses the AuthCache by the ticket.Name (Username) and sets the Principal by setting Context.User = user from the AuthCache. So in short, all these classes share the AuthCache, and I have, for thread synchronization, a lock() in the cache store method. No lock in the read method. The custom membership provider doesn't know about the cache, the MembershipService doesn't know about any HttpContext (so could be used outside of a web app), and the FormsService doesn't use any custom methods besides accessing the AuthCache to set the Context.User for the initial login, so it isn't dependent on a specific membership provider. The main thing I see now is that the AuthCache will be sharing a User object if a user logs in from multiple sessions. So I may have to change the key from just UserId to something else (maybe using something in the FormsAuthenticationTicket for the key?).

  • PHP file form question

    - by Jordan Pagaduan
    My Code : <?php function dbAdd($first_name , $image) { //mysql connect database code... mysql_query("INSERT INTO users SET first_name = '".$first_name."', image = '".$image."'"); $mysql_close($sql); } if($_SERVER['REQUEST_METHOD']=='POST') { dbAdd($_POST['first_name'], $_POST['image']); } ?> <form enctype="multipart/form-data" method="post" action=""> First Name : <input type="text" name="first_name" > Image : <input type="file" name="image"> <input type="submit"> </form> The form "file" is to upload. I know that. But I wonder how to get the values so I can put the path of image in the database. The code is already working. The $first_name can already save to the database. Thank you for the answers. Jordan Pagaduan

  • How to implement a .net 3-tier architecture using Winforms

    - by Anders Jakobsen
    I have for some time build n-tier Applications using a database server as the data tier, Winforms as the presentation tier and an ASP.NET asmx webservice in the middle to send back and forth untyped Datasets. While this approach has worked for me so far, it certainly does feel outdated today. What technologies should I use if I were to create a similar architectured application today? .net 4.0 technology is welcome. I still want a database server as the datatier and the asmx webservices should probably be replaced by WCF. I would still like to have the presentation tier running as a desktop application (Winforms or WPF) so ignore ASP.net for this question. My main question really comes down to what to use as business objects. I want something that is easier to bind to the interface than untyped Datasets and strongly-typed datasets feels very heavy. I also need something that can track changes to make sure users do not override each other's changes in the database. Will the Entity Framework 4 be usable for a scenario like this? Are there any thorough guides available?

  • Rails: Should partials be aware of instance variables?

    - by Alexandre
    Ryan Bates' nifty_scaffolding, for example, does this edit.html.erb <%= render :partial => 'form' %> new.html.erb <%= render :partial => 'form' %> _form.html.erb <%= form_for @some_object_defined_in_action %> That hidden state makes me feel uncomfortable, so I usually like to do this edit.html.erb <%= render :partial => 'form', :locals => { :object => @my_object } %> _form.html.erb <%= form_for object %> So which is better: a) having partials access instance variables or b) passing a partial all the variables it needs? I've been opting for b) as of late, but I did run into a little pickle: some_action.html.erb <% @dad.sons.each do |a_son| %> <%= render :partial => 'partial', :locals => { :son => a_son } %> <% end %> _partial.html.erb The son's name is <%= son.name %> The dad's name is <%= son.dad.name %> son.dad makes a database call to fetch the dad! So I would either have to access @dad, which would be going back to a) having partials access instance variables or I would have to pass @dad in locals, changing render :partial to <%= render :partial = 'partial', :locals = { :dad = @dad, :son = a_son } %, and for some reason passing a bunch of vars to my partial makes me feel uncomfortable. Maybe others feel this way as well. Hopefully that made some sense. Looking for some insight into this whole thing... Thanks!

  • IE History Tracking, IFRAMES, and Cross Domain error...

    - by peiklk
    So here's the deal. We have a Flash application that is running within an HTML file. For one page we call a legacy reporting system in ASP.NET that is within an IFRAME. This page then communicates back to the Flash application using cross-domain scripting (document.domain = "domain" is set in both pages. THIS ALL WORKS. Now the kicker. Flash has history tracking enabled. This loads the history.js file that created a div tag to store page changes so the back and forward buttons work in the browser. Which works for Firefox and Chrome as they create a div tag. HOWEVER In Internet Explorer, history.js creates another IFRAME (instead of a DIV) called ie_historyFrame. When the ScriptResource.axd code attempts to access this with: var frameDoc = this._historyFrame.contentWindow.document; we get an "Access is Denied" error message. ARGH! We've tried getting a handle to this IFRAME and inserting the document.domain code. FAIL. We've tried editing the historytemplate.html file that flex also uses to include document.domain... FAIL. I've tried to edit the underlying ASP.NET page to disable history tracking in the ScriptManager control. FAIL. At my wit's end on this one. We have users who need to use IE to access this site. They are big clients who we cannot tell to just use Firefox. Any suggestions would be greatly appreciated.

  • Binding Data to DataGridView in VB.Net

    - by Peter
    Hi, I have a bit of code which loads data from a stored procedure in MS SQL Server and then loads the data to a datagridview, which works fine. What i want is for the code that connects / loads the data to sit in my Database Class and then everything associated with the datagridview to be stored in my Form but i am having problems passing the contents of the bindingsource over to the Form from the Database Class.

  • ASP.NET Sql Timeout

    - by Petoj
    Well we have this Asp.Net application that we installed at a customer but now some times we get a SqlException that says "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." now the wired thing is that the exception comes instantly when i press the button, this does not happen every time i press the button so its random.. any idea what i could try to pinpoint the problem? We are using the EnterpriseLibrary Database block if that matters... Stack trace: at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, Boolean breakConnection) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning(TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.Run(RunBehavior runBehavior, SqlCommand cmdHandler, SqlDataReader dataStream, BulkCopySimpleResultSet bulkCopyHandler, TdsParserStateObject stateObj) at System.Data.SqlClient.SqlDataReader.ConsumeMetaData() at System.Data.SqlClient.SqlDataReader.get_MetaData() at System.Data.SqlClient.SqlCommand.FinishExecuteReader(SqlDataReader ds, RunBehavior runBehavior, String resetOptionsString) at System.Data.SqlClient.SqlCommand.RunExecuteReaderTds(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteDbDataReader(CommandBehavior behavior) at Microsoft.Practices.EnterpriseLibrary.Data.Database.DoExecuteReader(DbCommand command, CommandBehavior cmdBehavior) at Microsoft.Practices.EnterpriseLibrary.Data.Database.ExecuteReader(DbCommand command)

  • Sql Querying, group relationships

    - by Jordan
    Hi, Suppose I have two tables: Group ( id integer primary key, someData1 text, someData2 text ) GroupMember ( id integer primary key, group_id foreign key to Group.id, someData text ) I'm aware that my SQL syntax is not correct :) Hopefully is clear enough. My problem is this: I want to load a group record and all the GroupMember records associated with that group. As I see it, there are two options. A single query: SELECT Group.id, Group.someData1, Group.someData2 GroupMember.id, GroupMember.someData FROM Group INNER JOIN GroupMember ... WHERE Group.id = 4; Two queries: SELECT id, someData2, someData2 FROM Group WHERE id = 4; SELECT id, someData FROM GroupMember WHERE group_id = 4; The first solution has the advantage of only being one database round trip, but has the disadvantage of returning redundant data (All group data is duplicated for every group member) The second solution returns no duplicate data but involves two round trips to the database. What is preferable here? I suppose there's some threshold such that if the group sizes become sufficiently large, the cost of returning all the redundant data is going to be greater than the overhead involved with an additional database call. What other things should I be thinking about here? Thanks, Jordan

  • Accessing XUL anonymous content using C++

    - by Vaibhav Gade
    Hi All, I am writing Firefox extension using C++. I am trying to access XUL:tabox element in "TabOpen" event handler, but I am unable access any XUL element. I am putting here pseudocode of my extension for reference: HandleEvent() { if (event type is TabOpen) { nsCOMPtr<nsIDOMNode> OriginalNode = do_QueryInterface(event->GetTarget); nsCOMPtr<nsIDOMNodeList> childlist; // // Note here that I got OriginalNode's local name as "tabbrowser" // OriginalNode->GetChildNodes(getter_AddRefs(childlist)); PRUint32 len; childlist->GetLength(&len); // Return 1; consider only "popup" child element. nsString localName; nsCOMPtr<nsIDOMNode> node1; childlist->Item(0, getter_AddRefs(node1)); node1->GetLocalName(localName); // Returns "popup" as the local name. } } By traversing the DOM tree through DOM Inspector, I came to know that XUL elements are anonymous content. How do I access these XUL elements? Very Thanks in advance, Vaibhav.

  • C# - InvalidCastException when fetching double from sqlite

    - by Irro
    I keep getting a InvalidCastException when I'm fetching any double from my SQLite database in C#. The exception says "Specified cast is not valid." I am able to see the value in a SQL manager so I know it exists. It is possible to fetch Strings (VARCHARS) and ints from the database. I'm also able to fetch the value as an object but then I get "66.0" when it's suppose to be "66,8558604947586" (latitude coordination). Any one who knows how to solve this? My code: using System.Data.SQLite; ... SQLiteConnection conn = new SQLiteConnection(@"Data Source=C:\\database.sqlite; Version=3;"); conn.Open(); SQLiteDataReader reader = getReader(conn, "SELECT * FROM table"); //These are working String name = reader.GetString(1); Int32 value = reader.GetInt32(2); //This is not working Double latitude = reader.getDouble(3); //This gives me wrong value Object o = reader[3]; //or reader["latitude"] or reader.getValue(3)

  • How can I make a server log file available via my ASP.NET MVC website?

    - by Gary McGill
    I have an ASP.NET MVC website that works in tandem with a Windows Service that processes file uploads. For easy maintenance of the site, I'd like the log file for the Windows Service to be accessible (to me, only) via the website, so that I can hit http://myserver/logs/myservice to view the contents of the log file. How can I do that? At a guess, I could either have the service write its log file in a "Logs" folder at the top level of the site, or I could leave it where it is and set up a virtual directory to point to it. Which of these is better - or is there another, better way? Wherever the file is stored, I can see that there's going to be another problem. I tried out the first option (Logs folder in my website), but when I try to access the file via HTTP I get an error: The process cannot access the file 'foo' because it is being used by another process. Now, I know from experience that my service keeps the file locked for writing while it's running, but that I can still open the file in Notepad to view the current contents. (I'm surprised that IIS insists on write access, if that's what's happening). How can I get around that? Do I really have to write a handler to read the file and serve it to the browser myself? Or can I fix this with configuration or somesuch? PS. I'm using IIS7 if that helps.

  • Disable caching in JPA (eclipselink)

    - by James
    Hi, I want to use JPA (eclipselink) to get data from my database. The database is changed by a number of other sources and I therefore want to go back to the database for every find I execute. I have read a number of posts on disabling the cache but this does not seem to be working. Any ideas? I am trying to execute the following code: EntityManagerFactory entityManagerFactory = Persistence.createEntityManagerFactory("default"); EntityManager em = entityManagerFactory.createEntityManager(); MyLocation one = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); MyLocation two = em.createNamedQuery("MyLocation.findMyLoc").getResultList().get(0); System.out.println(one==two); one==two is true while I want it to be false. I have tried adding each/all the following to my persistence.xml <property name="eclipselink.cache.shared.default" value="false"/> <property name="eclipselink.cache.size.default" value="0"/> <property name="eclipselink.cache.type.default" value="None"/> I have also tried adding the @Cache annotation to the Entity itself: @Cache( type=CacheType.NONE, // Cache nothing expiry=0, alwaysRefresh=true ) Am I misunderstanding something? Thank you, James

  • Returning ifstream in a function

    - by wrongusername
    Here's probably a very noobish question for you: How (if at all possible) can I return an ifstream from a function? Basically, I need to obtain the filename of a database from the user, and if the database with that filename does not exist, then I need to create that file for the user. I know how to do that, but only by asking the user to restart the program after creating the file. I wanted to avoid that inconvenience for the user if possible, but the function below does not compile in gcc: ifstream getFile() { string fileName; cout << "Please enter in the name of the file you'd like to open: "; cin >> fileName; ifstream first(fileName.c_str()); if(first.fail()) { cout << "File " << fileName << " not found.\n"; first.close(); ofstream second(fileName.c_str()); cout << "File created.\n"; second.close(); ifstream third(fileName.c_str()); return third; //compiler error here } else return first; } EDIT: sorry, forgot to tell you where and what the compiler error was: main.cpp:45: note: synthesized method ‘std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)’ first required here EDIT: I changed the function to return a pointer instead as Remus suggested, and changed the line in main() to "ifstream database = *getFile()"; now I get this error again, but this time in the line in main(): main.cpp:27: note: synthesized method ‘std::basic_ifstream<char, std::char_traits<char> >::basic_ifstream(const std::basic_ifstream<char, std::char_traits<char> >&)’ first required here

  • Practical value for concurrent-request-timeout parameter

    - by Andrei
    In the Seam Reference Guide, one can find this paragraph: We can set a sensible default for the concurrent request timeout (in ms) in components.xml: <core:manager concurrent-request-timeout="500" /> However, we found that 500 ms is not nearly enough time for most of the cases we had to deal with, especially with the severe restriction seam places on conversation access. In our application we have a combination of page scoped ajax requests (triggered by various use actions), some global scoped polling notification logic (part of the header, so included in every page) and regular links that invoke actions and/or navigate to other pages. Therefore, we get the dreaded concurrent access to conversation exception way too often, even without any significant load on the site. After researching the options for quite a bit, we ended up bumping this value to several seconds (we're debating whether to bump it up to 10s), as none of the recommended solutions seemed able to solve our issue completely (even forcing a global queue for all the ajax requests would still leave us exposed to a user deciding to click a link right when one of our polling calls was in progress). And we'd much rather have the users wait for a second or two instead of getting an error page just because they clicked a link at the wrong moment. And now to the question: is there something obvious we're missing (like a way to allow concurrent access to conversations and taking care of the needed locking ourselves, for instance :)? How do people solve this problem (ajax requests mixed with user driven interaction) in seam? Disabling all the links on the page while ajax requests are in progress (as suggested by one blog page) is really not a viable option. Any other suggestions? TIA, Andrei

  • Increase Query Speed in PostgreSQL

    - by Anthoni Gardner
    Hello, First time posting here, but an avid reader. I am experiancing slow query times on my database (all tested locally thus far) and not sure how to go about it. The database itself has 44 tables and some of them tables have over 1 Million records (mainly the movies, actresses and actors tables). The table is made via JMDB using the flat files on IMDB. Also the SQL query that I am about to show is from that said program (that too experiances very slow search times). I have tried to include as much information as I can, such as the explain plan etc. "QUERY PLAN" "HashAggregate (cost=46492.52..46493.50 rows=98 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Append (cost=39094.17..46491.79 rows=98 width=46)" " - HashAggregate (cost=39094.17..39094.87 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on movies (cost=0.00..39093.65 rows=70 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Nested Loop (cost=0.00..7395.94 rows=28 width=46)" " Output: public.movies.title, public.movies.movieid, public.movies.year" " - Seq Scan on akatitles (cost=0.00..7159.24 rows=28 width=4)" " Output: akatitles.movieid, akatitles.language, akatitles.title, " Filter: (((title)::text ~~* '%Babe%'::text) AND ((title)::text !~~* '""%}'::text))" " - Index Scan using movies_pkey on movies (cost=0.00..8.44 rows=1 width=46)" " Output: public.movies.movieid, public.movies.title, public.movies.year, public.movies.imdbid" " Index Cond: (public.movies.movieid = akatitles.movieid)" SELECT * FROM ((SELECT DISTINCT title, movieid, year FROM movies WHERE title ILIKE '%Babe%' AND NOT (title ILIKE '"%}')) UNION (SELECT movies.title, movies.movieid, movies.year FROM movies INNER JOIN akatitles ON movies.movieid=akatitles.movieid WHERE akatitles.title ILIKE '%Babe%' AND NOT (akatitles.title ILIKE '"%}'))) AS union_tmp2; Returns 612 Rows in 9078ms Database backup (plain text) is 1.61GB It's a really complex query and I am not fully cognizant on it, like I said it was spat out by JMDB. Do you have any suggestions on how I can increase the speed ? Regards Anthoni

  • Query Months help

    - by StealthRT
    Hey all i am in need of some helpful tips/advice on how to go about my problem. I have a database that houses a "signup" table. The date for this table is formated as such: 2010-04-03 00:00:00 Now suppose i have 10 records in this database: 2010-04-03 00:00:00 2010-01-01 00:00:00 2010-06-22 00:00:00 2010-02-08 00:00:00 2010-02-05 00:00:00 2010-03-08 00:00:00 2010-09-29 00:00:00 2010-11-16 00:00:00 2010-04-09 00:00:00 2010-05-21 00:00:00 And i wanted to get each months total registers... so following the example above: Jan = 1 Feb = 2 Mar = 1 Apr = 2 May = 1 Jun = 1 Jul = 0 Aug = 0 Sep = 1 Oct = 0 Nov = 1 Dec = 0 Now how can i use a query to do that but not have to use a query like: WHERE left(date, 7) = '2010-01' and keep doing that 12 times? I would like it to be a single query call and just have it place the months visits into a array like so: do until EOF theMonthArray[0] = "total for jan" theMonthArray[1] = "total for feb" theMonthArray[2] = "total for mar" theMonthArray[3] = "total for apr" ...etc loop I just can not think of a way to do that other than the example i posted with the 12 query called-one for each month. This is my query as of right now. Again, this only populates for one month where i am trying to populate all 12 months all at once. SELECT count(idNumber) as numVisits, theAccount, signUpDate, theActive from userinfo WHERE theActive = 'YES' AND idNumber = '0203' AND theAccount = 'SUB' AND left(signUpDate, 7) = '2010-04' GROUP BY idNumber ORDER BY numVisits; The example query above outputs this: numVisits | theAccount | signUpDate | theActive 2 SUB 2010-04-16 00:00:00 YES Which is correct because i have 2 records within the month of April. But again, i am trying to do all 12 months at one time (in a single query) so i do not tax the database server as much when compared to doing 12 different query's... UPDATE I'm looking to do something like along these lines: if NOT rst.EOF if left(rst("signUpDate"), 7) = "2010-01" then theMonthArray[0] = rst("numVisits") end if if left(rst("signUpDate"), 7) = "2010-02" then theMonthArray[1] = rst("numVisits") end if etc etc.... end if Any help would be great! :) David

  • IPhone app with SSL client certs

    - by Pavel Georgiev
    I'm building an iphone app that needs to access a web service over https using client certificates. If I put the client cert (in pkcs12 format) in the app bundle, I'm able to load it into the app and make the https call (largely thanks to stackoverflow.com). However, I need a way to distribute the app without any certs and leave it to the user to provide his own certificate. I thought I would just do that by instructing the user to import the certificate in iphone's profiles (settings-general-profiles), which is what you get by opening a .p12 file in Mail.app and then I would access that item in my app. I would expect that the certificates in profiles are available through the keychain API, but I guess I'm wrong on that. 1) Is there a way to access a certificate that I've already loaded in iphone's profile in my app? 2) What other options I have for loading a user specified certificate in my app? The only thing I can come up with is providing some interface where the user can give an URL to his .p12 cerificate, which I can then load into the app's keychain for later use, but thats not exactly user-friednly. I'm looking for something that would allow the user to put the cert on phone (email it to himself) and then load it in my app.

    Hey This is my login script, using PHP5 and MYSQLi, I just had help spotting errors in my query, but still it will not let me login, even though the username and password are correct and in the database, it just keeps returning the error: your username and password do not match any in our db. But I know they do lol...could any body spot the problem? //Check if the form has been submitted if (isset($_POST['login'])) { //Check if username and password are empty if ($_POST['username']!='' && $_POST['password']!='') { //Create query to check username and password to database $validate_user = $mysqli->query('SELECT id, username, password, active FROM users WHERE = username = "'.$mysqli->real_escape_string($_POST['username']).'" AND password = "'.$mysqli->real_escape_string(md5($_POST['password'])).'"'); //We check if the query returns true if ($validate_user->num_rows == 1) { $row = $validate_user->fetch_assoc(); //Check if the user has activated there account if ($row['activated'] == 1) { $_SESSION['id'] = $row['id']; $_SESSION['logged_in'] = true; Header('Location: ../main/index.php'); } //Show this error if activation returns as 0 else { $error = '<p class="error">Please activate your account.</p>'; } } //Show this error if the details matched any in the db else { $error = '<p class="error">Your username and password are not in our database!</p>'; } } //Show this error if the username and password field have not been entered else { $error = '<p class="error">Please enter your username and password.</p>'; } }

  • Oracle JDBC intermittent Connection Issue

    - by Lipska
    I am experiencing a very strange problem This is a very simple use of JDBC connecting to an Oracle database OS: Ubuntu Java Version: 1.5.0_16-b02 1.6.0_17-b04 Database: Oracle 11g Release 11.1.0.6.0 When I make use of the jar file JODBC14.jar it connects to the database everytime When I make use of the jar file JODBC5.jar it connects some times and other times it throws an error ( shown below) If I recompile with Java 6 and use JODBC6.jar I get the same results as JODBC5.jar I need specific features in JODB5.jar that are not available in JODBC14.jar Any ideas Error Connecting to oracle java.sql.SQLException: Io exception: Connection reset at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:74) at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:110) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:171) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:227) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:494) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:411) at oracle.jdbc.driver.PhysicalConnection.(PhysicalConnection.java:490) at oracle.jdbc.driver.T4CConnection.(T4CConnection.java:202) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:33) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:474) at java.sql.DriverManager.getConnection(DriverManager.java:525) at java.sql.DriverManager.getConnection(DriverManager.java:171) at TestConnect.main(TestConnect.java:13) Code Below is the code I am using import java.io.; import java.sql.; public class TestConnect { public static void main(String[] args) { try { System.out.println("Connecting to oracle"); Connection con=null; Class.forName("oracle.jdbc.driver.OracleDriver"); con=DriverManager.getConnection( "jdbc:oracle:thin:@172.16.48.100:1535:sample", "JOHN", "90009000"); System.out.println("Connected to oracle"); con.close(); System.out.println("Goodbye"); } catch(Exception e){e.printStackTrace();} } }

  • N-Tier Architecture - Structure with multiple projects in VB.NET

    - by focus.nz
    I would like some advice on the best approach to use in the following situation... I will have a Windows Application and a Web Application (presentation layers), these will both access a common business layer. The business layer will look at a configuration file to find the name of the dll (data layer) which it will create a reference to at runtime (is this the best approach?). The reason for creating the reference at runtime to the data access layer is because the application will interface with a different 3rd party accounting system depending on what the client is using. So I would have a separate data access layer to support each accounting system. These could be separate setup projects, each client would use one or the other, they wouldn't need to switch between the two. Projects: MyCompany.Common.dll - Contains interfaces, all other projects have a reference to this one. MyCompany.Windows.dll - Windows Forms Project, references MyCompany.Business.dll MyCompany.Web.dll - Website project, references MyCompany.Business.dll MyCompany.Busniess.dll - Business Layer, references MyCompany.Data.* (at runtime) MyCompany.Data.AccountingSys1.dll - Data layer for accounting system 1 MyCompany.Data.AccountingSys2.dll - Data layer for accounting system 2 The project MyCompany.Common.dll would contain all the interfaces, each other project would have a reference to this one. Public Interface ICompany ReadOnly Property Id() as Integer Property Name() as String Sub Save() End Interface Public Interface ICompanyFactory Function CreateCompany() as ICompany End Interface The project MyCompany.Data.AccountingSys1.dll and MyCompany.Data.AccountingSys2.dll would contain the classes like the following: Public Class Company Implements ICompany Protected _id As Integer Protected _name As String Public ReadOnly Property Id As Integer Implements MyCompany.Common.ICompany.Id Get Return _id End Get End Property Public Property Name As String Implements MyCompany.Common.ICompany.Name Get Return _name End Get Set(ByVal value as String) _name = value End Set End Property Public Sub Save() Implements MyCompany.Common.ICompany.Save Throw New NotImplementedException() End Sub End Class Public Class CompanyFactory Implements ICompanyFactory Public Function CreateCompany() As ICompany Implements MyCompany.Common.ICompanyFactory.CreateCompany Return New Company() End Function End Class The project MyCompany.Business.dll would provide the business rules and retrieve data form the data layer: Public Class Companies Public Shared Function CreateCompany() As ICompany Dim factory as New MyCompany.Data.CompanyFactory Return factory.CreateCompany() End Function End Class Any opinions/suggestions would be greatly appreciated.

  • IRC Server configuration possibilities

    - by Katai
    I need to know a couple of things, concerning IRC servers that I couldnt directly find out over google (or werent clear enough for me to be sure if it actually works) I'm working at a larger community site, and wanted to deliver an in-page chat. Since it would be a nice feature to let people access it from outside too, over their own clients, I tought implementing an IRC Server would be the best solution (probably dedicated, I'll have to teach myself a couple of things for that) I plan to include a Web-based IRC client over an APE Client / Server. The problem is, I want to strip down the user rights, to disallow many functionalities that IRC would offer: Change of nicknames: The user logs in over the Page login, and I'll automatically create an IRC auth for this user with that password. So basically, he would connect to the IRC client over a button. And after connecting, he shouldnt be able to change his nickname at all Creating channels: I want the possibility to create channels, but not from 'normal' users. Basically, I would prefer to set up basic channels that are public, and if a user really creates an own channel, that one should be private and via invitation (is that possible?) Private conversations: private conversations should be filtered out from the allaround IRC client, into separate 'in-browser-windows' that I create over JS. I guess I just have to filter the stuff coming from IRC - or is there a better solution to that? Only 'registered' users have access: Like I said, if someone registers on the page, I would like to create an IRC 'account' for him. Users that arent registered on the page, cant access the IRC server at all (or get thrown out). Mainly to avoid spammers or bots from outside. Is this stuff solvable over IRC? I've read some FAQ's and Instructions for IRC OP's and servers, but I couldnt find a clear answer - it seems that everyone can do pretty much everything - I would like to configure it in a way that user possibilities are more cut down. Basically, giving users the possibility to chat, but not more. So the Question basically is, how possible / solvable this issues are allaround, or if I have to find other solutions for this.

  • Dynamic programming in VB

    - by Rahul Jain
    Hello Everybody, We develop applications for SAP using their SDK. SAP provides a SDK for changing and handling events occuring in the user interface. For example, with this SDK we can catch a click on a button and do something on the click. This programming can be done either VB or C#. This can also be used to create new fields on the pre-existing form. We have developed a specific application which allows users to store the definition required for new field in a database table and the fields are created at the run time. So far, this is good. What we require now is that the user should be able to store the validation code for the field in the database and the same should be executed on the run time. Following is an example of such an event: Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent Dim oForm As SAPbouiCOM.Form If pVal.FormTypeEx = "ACC_QPLAN" Then If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then oProdRec.ItemPressEvent(pVal) End If End If End Sub Public Sub ItemPressEvent(ByRef pVal As SAPbouiCOM.ItemEvent) Dim oForm As SAPbouiCOM.Form oForm = oSuyash.SBO_Application.Forms.GetForm(pVal.FormTypeEx, pVal.FormTypeCount) If pVal.EventType = SAPbouiCOM.BoEventTypes.et_LOST_FOCUS And pVal.BeforeAction = False Then If pVal.ItemUID = "AC_TXT5" Then Dim CardCode, ItemCode As String ItemCode = oForm.Items.Item("AC_TXT2").Specific.Value CardCode = oForm.Items.Item("AC_TXT0").Specific.Value UpdateQty(oForm, CardCode, ItemCode) End If End If End Sub So, what we need in this case is to store the code given in the ItemPressEvent in a database, and execute this in runtime. I know this is not straight forward thing. But I presume there must be some ways of getting these kind of things done. The SDK is made up of COM components. Thanks & Regards, Rahul Jain

  • How to serve tiff WMS imagery through GeoServer

    - by mikem419
    Ok so I am new to the GeoServer/database world. I am a student intern and I have been given the task of setting up a WMS using GeoServer. I have never done any database work before this so bare with me if my questions leave out important information. I am using GeoServer 2.0.1 in standalone mode (downloaded using Jetty) with PostgreSQL 8.4 installed. I went through nyc_roads and nyc_buildings install demo in the GeoServer documentation but I still do not understand how I should go about serving up some test images. I noticed that the nyc_roads setup included a .sql file that was responsible for setting up the nyc_buildings database. I do not know how/where this file was generated. Our test images are .tiff and .jpeg. I have successfully been able to do a WMS call on the local GeoServer machine, and have opened the included demo imagery. I now wish to add these .tiff and .jpeg images to GeoServer and access them through WMS. I have tried copying the images to the GeoServer data directory,adding a new data store, and layers, but I always receive an error regarding the "input stream." Again I am very sorry if I am leaving out allot of vital information, this is as much as I know. thanks!
