  • ClassNotFoundException com.mysql.jdbc.Driver

    - by Dusk
    This question might have asked here number of times . After doing some google search for the above error and doing some update, I can't understand why I'm still getting that error. I've already put my driver-- mysql-connector-java-5.1.5-bin in the classpath: Java_Home\jre\lib\ Java_Home\jre\lib\ext\ Java_Home\lib and the code which I'm using to connect to mysql database is: try{ Class.forName("com.mysql.jdbc.Driver"); Connection con=DriverManager.getConnection("jdbc:mysql://localhost:3306/mail","root",""); Statement stmt = con.createStatement(); ResultSet rs = stmt.executeQuery("select message_body from deadletter"); String dbtime; while (rs.next()) { dbtime = rs.getString(1); System.out.println(dbtime); } con.close(); } catch (SQLException e) { System.out.println("Connection Failed! Check output console"); e.printStackTrace(); } } and the complete stacktrace of the above exception is: java.lang.ClassNotFoundException: com.mysql.jdbc:Driver at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:307) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:320) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:169) at mail.main(mail.java:114) Now, what's wrong I'm doing here?

  • connecting to MySQL using JDBC in eclipse

    - by Noona
    Hello, So I want to create a JDBC connection to MySQL server that is installed on my pc, here are the steps, I installed MySQL with the username and password "root", downloaded mysql-connector-java and from theere I coped the JAR "mysql-connector-java-5.1.12-bin" to "C:\Sun\SDK\jdk\jre\lib\ext", I then added it as an external JAR in my project in eclipse, now in my class I have this code: public void initialiseDatabase() { try { // Load the Driver class. Class.forName("com.mysql.jdbc.Driver"); //Create the connection using the static getConnection method databaseConnection = DriverManager.getConnection (databaseUrl+databaseName, dbUserName, dbPassword); sqlStatement = databaseConnection.createStatement(); } catch (SQLException e) {e.printStackTrace();} catch (Exception e) {e.printStackTrace();} } (this is going to be psuedocode cause I am reading from a properties file and don't want the one helping me reading through long lines of code from main to figure out all the variables), where databaseUrl = "127.0.0.1" dbUserName = "root" dbPassword = "root" databaseName = "MySQL" //this one I am not sure of, do I need to create it or is it set inherenrly? now the MySQL server is up and running, but when I call the method initialiseDatabase the following exception is thrown: "java.sql.SQLException: No suitable driver found for rootroot at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at Proxy$JDBCConnection.initialiseDatabase(Proxy.java:721)" when line 721 is: sqlStatement = databaseConnection.createStatement(); Where have I gone wrong? thanks

  • Making "helper" windows in WPF

    - by RandomEngy
    I'm writing an app in WPF and want to make a "helper" window. The window needs to be resizable, with no minimize option and doesn't show in the taskbar. If the app receives focus, it should appear as well, but whether or not it's in front or behind the main window should be retained. When the main window is closed, it should close along with the app. An example is a detached pane in Visual Studio. I've made the helper windows not appear in the taskbar, but can't get the rest of the behaviors I want. If they're their own windows, they don't get focus along with the rest of the app. If I specify a the main window as their owner, the main window can't be on top of the helper window. Anyone know a good way to approach this?

  • Handle mysql restart in SQLAlchemy

    - by wRAR
    My Pylons app uses local MySQL server via SQLAlchemy and python-MySQLdb. When the server is restarted, open pooled connections are apparently closed, but the application doesn't know about this and apparently when it tries to use such connection it receives "MySQL server has gone away": File '/usr/lib/pymodules/python2.6/sqlalchemy/engine/default.py', line 277 in do_execute cursor.execute(statement, parameters) File '/usr/lib/pymodules/python2.6/MySQLdb/cursors.py', line 166 in execute self.errorhandler(self, exc, value) File '/usr/lib/pymodules/python2.6/MySQLdb/connections.py', line 35 in defaulterrorhandler raise errorclass, errorvalue OperationalError: (OperationalError) (2006, 'MySQL server has gone away') This exception is not caught anywhere so it bubbles up to the user. If I should handle this exception somewhere in my code, please show the place for such code in a Pylons WSGI app. Or maybe there is a solution in SA itself?

  • Extract page from PDF using iText and clojure

    - by KobbyPemson
    I am trying to extract a single page from a pdf with clojure by translating the splitPDF method I found here http://viralpatel.net/blogs/itext-tutorial-merge-split-pdf-files-using-itext-jar/ I keep getting this error IOException Stream Closed java.io.FileOutputStream.writeBytes (:-2) This prevents me from opening the document while the repl is still open. Once I close the repl I'm able to access the document. Why do I get the error? How do I fix it ? How can I make it more clojurey?

  • How to monitor MySQL query errors, timeouts and logon attempts?

    - by Abel
    While setting up a third party closed source CMS (Sitefinity) the setup doesn't create all tables and procedures necessary to run it. The software lacks a logging system itself and it made me wonder: could I trace and monitor failing SQL statements from MySQL? This serves more than only the purpose of solving my issue with Sitefinity. More often I wonder what's send to the MySQL server, not wanting to dive into the software products or setup a debugging environment etc. I tried JetProfiler (only performance) and looked through a few others, but although they monitor a lot, they don't monitor query failures, timeouts or logon attempts. Does anyone know a profiler, tracer, monitoring tool, commercial or free, that can show me this information?

  • Need Ontology of software engineering terms

    - by v.rekha
    I'm trying to implement a Question Answering System based on software engineering ontology. This is a [class/university?] project; it will use the java language. Can you please help me locate software engineering ontologies i.e. ontologies [or even taxonomies / folksonomies ?] that include words and concepts found in the domain of Software Engineering. Editor's note: I took the liberty of rewriting this question. It was initially poorly worded and being misunderstood was closed. Maybe it can be reopen, for it is programming related and of interest to some SO contributors. According to this dupe: the poster is looking for an OWL resource: quote, "I need software engineering ontology.owl file."

Then the line e.Cancel = true is executed and the form is not closed. Now the thing is, after this if i close the application from task manager the close reason is UserClosing !!! Why? Shouldn't it be TaskManagerClosing?

  • CRM plugin to execute when opportunity is reopened

    - by splatto
    I need to write a plugin for Dynamics CRM 4.0 that executes when a closed opportunity is reopened in order to change the salesstagecode. My questions are: When I register a new step to the plugin, what attribute(s) should I filter on? What property on the entity should I check the value of? and What should I look for the value of this entity to be so I can determine if the plugin execution should continue? I've typically written asynchronous workflows and my experience writing plugins is still developing, so I'd appreciate any help and clarification that can be offered. Please see below the plugin skeleton I've written public void Execute(IPluginExecutionContext context) { if (context.InputParameters.Properties.Contains("Target") && context.InputParameters.Properties["Target"] is DynamicEntity) { ICrmService service = context.CreateCrmService(false); DynamicEntity entity = (DynamicEntity)context.InputParameters.Properties["Target"]; if (entity.Name == EntityName.opportunity.ToString()) { if (entity.Properties.Contains(/*What Property Should I Check Here?*/)) { //And what value should I be looking for in that property? } } } }

  • C# CF: file encryption/decryption on the fly

    - by nuttynibbles
    Hi, i've seen many article on encrypt/decrypt of file and typically a button is used to choose the file for encrypt and another button to decrypt the file. i've seen some application like truecrypt and probably others which does file encryption on-the-fly with transparent. this means that when a encrypted file is clicked to access, it will automatically decrypt and play/open the file. then when the file is closed, it will automatically encrypt again. some have said that the only way to detect file open is through file system filter. but is there other ways to do this in c# compact framework?

  • Database for Python Twisted

    - by Will
    There's an API for Twisted apps to talk to a database in a scalable way: twisted.enterprise.dbapi The confusing thing is, which database to pick? The database will have a Twisted app that is mostly making inserts and updates and relatively few selects, and then other strictly-read-only clients that are accessing the database directly making selects. (The read-only users are not necessarily selecting the data that the Twisted app is inserting; its not as though the database is being used as a message-queue) My understanding - which I'd like corrected/adviced - is that: Postgres is a great DB, but all the Python bindings - and there is a confusing maze of them - are abandonware There is psycopg2, but that makes a lot of noise about doing its own connection-pooling and things; does this co-exist gracefully/usefully/transparently with the Twisted async database connection pooling and such? SQLLite is a great database for little things but if used in a multi-user way it does whole-database locking, so performance would suck in the usage pattern I envisage MySQL - after the Oracle takeover, who'd want to adopt it now or adopt a fork? Is there anything else out there?

  • codemirror fails when adding </textarea> tag inside it

    - by Jorre
    I'm using codemirror http://marijn.haverbeke.nl/codemirror/ to let users create their own web templates inside a web application. Codemirror works great, except for the time that users have put a tag inside their source code. When I load that up inside code mirror, it breaks everything in the source code that follows after because it thinks my codemirror text area is closed. I'm using the following way to launch codemirror: CodeMirror.fromTextArea('code') It works great on my existing textarea "code" except when users add inside their templates (in the codemirror textarea). Any help is much appreciated!

  • NetworkStream.Read delay .Net

    - by Gilbes
    I have a class that inherits from TcpClient. In that class I have a method to process responses. In that method I call I get the NetworkStream with MyBase.GetStream and call Read on it. This works fine, excpet the first call to read blocks too long. And by too long I mean that the socket has recieved plenty of data, but won't read it until some arbitrary limit is reached. I can see that it has recieved plenty of data using the packet sniffer WireShark. I have set the recieve buffer to small amounts, and very small amounts (like just a few bytes) to no avail. I have done the same with the buffer byte array I pass to the read method, and it still delays. Or to put it another way. I am download 600k. The download takes 5 seconds (at a little over 100k/second connection to the server which makes sense). The initial Read call takes 2-3 seconds and tells me only 256 bytes are availble (256 is the Recieve buffer and the size of the array I read in to). Then magically, the other few hundred thousand bytes can be read in 256 byte chunks in only a few process ticks each. Using a packet sniffer, I know that during those initial 2-3 seconds, the socket has recieved much more than just 256 bytes. My connection wasn't .25k/second for 3 seconds and then 400k for 2 seconds. How do I get the bytes from a socket as they come in?

  • jQuery Toggle Cookie Support

    I'm trying to implement the jQuery Cookie plugin into my slide toggle script, but so far haven't been successful. Here's my code (without any cookie implementation): jQuery: $(document).ready(function() { $('a.toggle').click(function() { var id = $(this).attr('name'); $('#module' + id).slideToggle('fast'); $('a.toggle[name='+id+']').toggle(); return false; }); }); HTML: <a class="toggle" name="1" href="#">- Hide</a> <a class="toggle hidden" name="1" href="#">+ Show</a> <div id="module1"><p>Hello World</p></div> Anyone know if it's easy enough to implement the jQuery Cookie plugin into my existing code so it remembers the open/closed state? Thank you.

  • How can I easily make a java application invisible to the user?

    - by Pedro Bellora
    Hello! I have developed a Java aplication that is currently being run by double-clicking on a ".bat" file that does something like "java -jar proy.jar". This application just listens on a port and writes to a database, so it does not have any user interface (such as a window). I need this application to run as in background mode, or as it where a service, but I don't really anything more than that. It's enough if the application is run in a way that is not noticeable by the user, so that the user is not bothered and so the application can not be mistakenly closed. By the way, this will be run on an specific computer so it's okay if I have to do any manual configuration ir order to make this work. Also, I need this application to run on startup. Any help/tips regarding this? In advance, thank you very much for your help! Regards, Pedro

  • C# connect to domain SQL Server 2005 from non-domain machine

    - by user304582
    Hi, I asked a question a few days ago (http://stackoverflow.com/questions/2795723/access-to-sql-server-2005-from-a-non-domain-machine-using-windows-authentication) which got some interesting, but not usable suggestions. I'd like to ask the question again, but make clear what my constraints are: I have a Windows domain within which a machine is running SQL Server 2005 and which is configured to support only Windows authentication. I would like to run a C# client application on a machine on the same network, but which is NOT on the domain, and access a database on the SQL Server 2005 instance. I CANNOT create or modify OS or SQL Server users on either machine, and I CANNOT make any changes to permissions or impersonation, and I CANNOT make use of runas. I know that I can write Perl and Java applications that can connect to the SQL Server database using only these four parameters: server name, database name, username (in the form domain\user), and password. In C# I have tried various things around: string connectionString = "Data Source=server;Initial Catalog=database;User Id=domain\user;Password=password"; SqlConnection connection = new SqlConnection(connectionString); connection.Open(); and tried setting integrated security to true and false, but nothing seems to work. Is what I am trying to do simply impossible in C#? Thanks for any help, Martin

  • DataReader Behaviour With SQL Server Locking

    - by Graham
    We are having some issues with our data layer when large datasets are returned from a SQL server query via a DataReader. As we use the DataReader to populate business objects and serialize them back to the client, the fetch can take several minutes (we are showing progress to the user :-)), but we've found that there's some pretty hard-core locking going on on the affected tables which is causing other updates to be blocked. So I guess my slightly naive question is, at what point are the locks which are taken out as a result of executing the query actually relinquished? We seem to be finding that the locks are remaining until the last row of the DataReader has been processed and the DataReader is actually closed - does that seem correct? A quick 101 on how the DataReader works behind the scenes would be great as I've struggled to find any decent information on it. I should say that I realise the locking issues are the main concern but I'm just concerned with the behaviour of the DataReader here.

    Hello everybody I am trying to implement an ihttphandeler for streaming files. files may be tiny thumbnails or gigantic movies the binaries r stored in sql server i looked at a lot of code online but something does not make sense isnt streaming supposed to read the data piece by piece and move it over the line? most of the code seems to first read the whole field from mssql to memory and then use streaming for the output writing wouldnt it b more eficient to actually stream from disk directly to http byte by byte (or buffered chunks?) heres my code so far but cant figure out the correct combination of the sqlreader mode and the stream object and the writing system Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest context.Response.BufferOutput = False Dim FileField=safeparam(context.Request.QueryString("FileField")) Dim FileTable=safeparam(context.Request.QueryString("FileTable")) Dim KeyField=safeparam(context.Request.QueryString("KeyField")) Dim FileKey=safeparam(context.Request.QueryString("FileKey")) Using connection As New SqlConnection(ConfigurationManager.ConnectionStrings("Main").ConnectionString) Using command As New SqlCommand("SELECT " & FileField & "Bytes," & FileField & "Type FROM " & FileTable & " WHERE " & KeyField & "=" & FileKey, connection) command.CommandType = Data.CommandType.Text enbd using end using end sub please be aware that this sql command also returns the file extension (pdf,jpg,doc...) in the second field of the query thank you all very much

  • How to capture SQL with parameters substituted in? (.NET, SqlCommand)

    - by Bryan
    Hello, If there an easy way to get a completed SQL statement back after parameter substitution? I.e., I want to keep a logfile of all the SQL this program runs. Or if I want to do this, will I just want to get rid of Parameters, and do the whole query the old school way, in one big string? Simple Example: I want to capture the output: SELECT subcatId FROM EnrollmentSubCategory WHERE catid = 1 .. from this code: Dim subCatSQL As String = "SELECT subcatId FROM EnrollmentSubCategory WHERE catid = @catId" Dim connectionString As String = "X" Dim conn As New SqlConnection(connectionString) If conn.State = ConnectionState.Closed Then conn.Open() End If Dim cmd As New SqlCommand(subCatSQL, conn) With cmd .Parameters.Add(New SqlParameter("@catId", SqlDbType.Int, 1)) End With Console.WriteLine("Before: " + cmd.CommandText) cmd.Prepare() Console.WriteLine("After: " + cmd.CommandText) I had assumed Prepare() would do the substitutions, but apparently not. Thoughts? Advice? Thanks in advance.
