• Hibernate bug using Oracle?

  - by Lothar

  Hello, I've got the problem, that I use a property in the persistence.xml which forces Hibernate to look only for tables in the given schema. <property name="hibernate.default_schema" value="FOO"/> Because we are using now 4 different schemas the actual solution is to generate 4 war files with a modified persistence.xml. That not very elegant. Does anybody know, how I can configure the schema with a property or by manipulation the JDBC connection string? I'm using Oracle 10g, 10_2_3 Patch. Thanks a lot.

• Trying to get JQuery Autocomplete working on Asp.Net page.

  - by JasonMHirst

  Can someone shed some light on the problem please: I have the following: $(document).ready(function () { $("#txtFirstContact").autocomplete({url:'http://localhost:7970/Home/FindSurname' }); }); On my Asp.Net page. The http request is a function on an MVC Controller and that code is here: Function FindSurname(ByVal surname As String, ByVal count As Integer) Dim sqlConnection As New SqlClient.SqlConnection sqlConnection.ConnectionString = My.Settings.sqlConnection Dim sqlCommand As New SqlClient.SqlCommand sqlCommand.CommandText = "SELECT ConSName FROM tblContact WHERE ConSName LIKE '" & surname & "%'" sqlCommand.Connection = sqlConnection Dim ds As New DataSet Dim da As New SqlClient.SqlDataAdapter(sqlCommand) da.Fill(ds, "Contact") sqlConnection.Close() Dim contactsArray As New List(Of String) For Each dr As DataRow In ds.Tables("Contact").Rows contactsArray.Add(dr.Item("ConSName")) Next Return Json(contactsArray, JsonRequestBehavior.AllowGet) End Function As far as I'm aware, the Controller is returning JSON data, however I don't know if the Function Parameters are correct, or indeed if the format returned is interprettable by the AutoComplete plugin. If anyone can assist in the matter I'd really appreciate it.

• "remote file operation failed" on Hudson

  - by Aveen

  I am running a Windows slave for Husdon 1.337 (Linux master). When running a project on the Windows node, it fails with the following message: Building remotely on winTestSlave Checking out a fresh workspace because there's no workspace at C:\hudson\***\ejb remote file operation failed It did work yesterday and I have not upgraded Hudson or changed its configurations (or the slave's configurations) in any way. I establish the connection between the slave and the master by running the following command on a cygwim prompt on the slave: java -jar slave.jar -jnlpUrl http://myserver/computer/winTestSlave/slave-agent.jnlp I saw the issue http://issues.hudson-ci.org/browse/HUDSON-5374 and did as instructed in the work-around but that did not work. I also tried with a newer version of slave.jar (version 1.356) but that did not work either. Does anyone please have any idea of how to fix this? I really cannot find more information anywhere else!

• Weblogic Error - Method not supported : Statement.cancel

  - by manetic

  I am running an application on Weblogic 9.2 MP3, currently having problem with connection pool. ERROR - UserBean retrieving user record. weblogic.jdbc.extensions.PoolLimitSQLException: weblogic.common.resourcepool.ResourceLimitException: No resources currently available in pool MyApp Data Source to allocate to applications, please increase the size of the pool and retry.. I also kept getting below error message, saying "Method not supported : Statement.cancel()" which I think it is the cause to the error above. <Error> <JDBC> <BEA-001131> <Received an exception when closing a cached statement for the pool "MyApp Data Source": java.sql.SQLException: Method not supported : Statement.cancel()..> I went through the app source code, this method didn't seem to be used by the app at all. Just though it might be something to do with weblogic itself. Anyone have any idea to fix this error?

• Basic Client-Server Design for persistent connections?

  - by cam

  Here's as far as I understand it: Client & Server make connection Client sends server data Server interprets data, sends client data So on, and so forth, until client sends disconnect signal. I'm just wondering about implementation. Step 2 and 3 are confusing to me, maybe I'm over-complicating it. Is there anymore to interpreting the data than a giant switch statement? Any good books on client/server design? Specifically talking about multithreaded servers, scalability, and message design (byte 1 = header info, byte 2 = blah blah, etc)? Specifically geared towards C++.

• Reusing of a PreparedStatement between methods?

  - by MRalwasser

  We all know that we should rather reuse a JDBC PreparedStatement than creating a new instance within a loop. But how to deal with PreparedStatement reuse between different method invocations? Does the reuse-"rule" still count? Should I really consider using a field for the PreparedStatement or should I close and re-create the prepared statement in every invocation? (Of course an instance of such a class would be bound to a Connection which might be a disadvantage) I am aware that the ideal answer might be "it depends". But I am looking for a best practice for less experienced developers that they will do the right choice in most of the cases.

• How to read a column in a tab-delimited Excel file in C#?

  - by janejanejane

  I have some data of an excel file below. At first, I figured that reading from the file could be done using the Excel Library then using an OLEDB connection. I managed to get the DocumentNo column data with the OLEDB approach. However, when the excel file is closed, I am unable to do the operation because it gives an error that "External table is not in the expected format." How can I read from the file even if it is closed? 10/4/2010 Paid Documents for Document Tracking - Customer 1 Paid Documents for Document Tracking - Customer CoCd Customer Trans.type SG Clearing Clrng doc.

• controling individual pins on a serial port

  - by Faken

  I know that serial ports work by sending a single stream of bits in serial. I can write programs to send and receive data from that one pin. However, there are a lot more other pins on the serial port connection that normal aren't used but from documentation all seem to have some sort of function for signalling as opposed to data transfer. Is it possible in any way to cause the other pins that are not used for direct data transfer to be controlled individual? If so, how would i go about doing that?

• Need to know who is hogging my bandwidth?

  - by Dev

  I have an ethernet connection to my iMac and with Internet sharing I am broadcasting the wireless network from my mac rather than using a wireless router. I use it to connect other devices wirelessly to the internet. But this makes all the traffic flow through my iMac. I wanted a way to analyze the traffic so that I know what connected devices are hogging the bandwidth at a given time and from which websites? I installed wireshark for mac and played around a little but it seems like an overkill when you first look at it. Can someone please help with few instructions to get what I need or any other way other than using wireshark? Thanks Dev.

  Hi, I just got my ssl certificate to work for the first time. For some reason when I connect to my website using https my browser tries to download the php file.

• Create a service that connects to remote database and uses public key encryption

  - by Leedsoft Solutions

  I have been searching all day and reading many tutorials and still I am confused. I am working on a project that has the following requirements as specified by the client (customer - not to be confused with client app): Connect to a remote server and verify that connection was successful. Connect to Web service on said server via SOAP. Authenticate with service using public key encryption Upon successful authentication, push a list of products and categories to a MSSQL database on remote server via the Web service. The client is a Winforms application written in C#. So far, I have created a WCF Service Application with separate services for the products and categories but I cannot figure the rest out. Can anyone point me in the direction of a tutorial or tutorials that cover these requirements? Many thanks in advance! Joe

• When to use memberEnd and when navigableOwnedEnd in an UML class diagram?

  - by Ivan

  I've download a trial of Altova UModel and am starting using UML. As a practical beginning I am modelling a personal information manager application, which includes a web bookmark managing. A Bookmark can belong to many (or no) Tags at once and a Tag can contain many (or no if all the bookmarks it contained were deleted) bookmarks. The relation has to be both-way navigable - a user has to be able to see all Bookmarks with a particular Tags ans all Tags of a Bookmark. What is the correct UML relation between Bookmark and Tag classes? As far as I understand UML now, it is an Association (not an Aggregation). But for a 2-way navigable many-to-many relation I can specify ends roles as "memberEnd" or "when navigableOwnedEnd", graphically the connection looks the same in both cases (an arrow) (which as I understand means navigability) but a property appears in the class box in case only when "memberEnd" is used. How should I specif it in the model If I mean both-way navigable many-to-many relation there?

• chatbot using twisted and wokkel

  - by dmitriy k.

  I am writing a chatbot using Twisted and wokkel and everything seems to be working except that bot periodically logs off. To temporarily fix that I set presence to available on every connection initialized. Does anyone know how to prevent going offline? (I assume if i keep sending available presence every minute or so bot wont go offline but that just seems too wasteful.) Suggestions anyone? Here is the presence code: class BotPresenceClientProtocol(PresenceClientProtocol): def connectionInitialized(self): PresenceClientProtocol.connectionInitialized(self) self.available(statuses={None: 'Here'}) def subscribeReceived(self, entity): self.subscribed(entity) self.available(statuses={None: 'Here'}) def unsubscribeReceived(self, entity): self.unsubscribed(entity) Thanks in advance.

• "derivative work" and the consumption of web services

  - by yodaj007

  From the Wowhead Terms of Service: "Intellectual Property Rights The Service and any necessary software used in connection with the Service ("Software") contain proprietary and confidential information that is protected by applicable intellectual property and other laws. You agree not to modify, rent, lease, loan, sell, distribute or create derivative works based on the Service or the Software, in whole or in part." Does this mean that I can't write a program to consume a web service being published by the writers of this TOS? I find it kind of scary that I even have to ask this question. The wikipedia article on "derivative works" isn't very conclusive.

• Moving to OOP hopefully!

  - by Luke

  So I am trying to understand OOP more and use it. The following code was written before i started using OOP. //loop through all the users $game = "$_POST[Game]_teams"; $result = mysql_query("SELECT username FROM `users`") or die(mysql_error()); while( $row=mysql_fetch_assoc($result) ) { $u[] = $row['username']; } I have put the query into my database page like following: function selectAllUsers() { $q = "SELECT username FROM ".TBL_USERS.""; mysql_query($q, $this->connection); } I'm a little confused about how the rest could be different? Would it be? Is it possible for anyone to help me without more code or understanding of my structure?

• Sync offline JQuery Mobile form

  - by Dimas

  My name is Dimas and I work as a developer in a hospital. I've developed a web form with JQuery Mobile which is accessed from an Android tablet. It sends data (text and FILES) to the server (PHP) and it's saved in a MySQL database. This tablets are used by doctors that are visiting the patients in their homes. Some of these patients live in remote areas with very bad Internet connection, so I'm thinking on use HTML5 Offline feature to solve these situations. I started reading about it but I'm newbie with this technology. I've some questions: Do you think this is the best/easiest solution? If I could save the form data in a local sqlite storage when the tablet is offline, how I could synchronize it with the data in MySQL server when the tablet become online? Thanks

  I have a big problem opening http://localhost/ on Windows 7 (beta). I installed this os and everything went great; when I installed Wamp I saw that localhost is not working at all. I just see this error: Failed to Connect Firefox can't establish a connection to the server at localhost. in Mozilla and Explorer. I removed Wamp and after some weeks (that means two weeks from today) I installed NetBeans on Windows 7. I created a test PHP script and when I debug it, I get the same error again. I tried to access it with ip 127.... but still the same. What is the problem? When i installed NetBeans I installed it in port 8080.

• Android internet connectivity check problem

  - by Chaoz

  Hello, I'm new to Android development and working on an Android application that requires the phone to be connected to the internet, through either Wifi, EDGE or 3G. This is the code that I'm using: public static boolean isConnected() { ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); return cm.getActiveNetworkInfo().isConnectedOrConnecting(); } I've also set these permissions in the manifest file: <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> This works fine in the emulator running version 1.5 of Android when 3G is enabled, but it crashes when I disable the 3G connection. My application throws a null pointer exception when I call isConnectedOrConnecting(). Hope that anyone knows the solution to this. Thanks in advance!

• Why for only some actions must I call setTarget?

  - by Max Pierce

  For most actions, I just click and drag in InterfaceBuilder to "wire up" a call from some interface object to my code. For example, if I want to know when the user single-clicks a row in a table, I drag a connection from the table's action to my controller's action. But now let's consider the user double-clicking a row. If I want one of my actions to be called when this happens, I need to call not only -[NSTableView setDoubleAction] but also -[NSControl setTarget]. Why? To be clear, I am not asking why Interface Builder doesn't support setDoubleAction. All tools have limitations. I am trying to gain a greater understanding about how and why setTarget doesn't seem to be necessary unless and until I want setDoubleAction to work. Another way to ask this question would be: Why don't I need to do anything in Interface Builder to set the target of the table's (single-click) action?

• Mysqli prepared insert statements always returning false

  - by user1754679

  I'm writing prepared statements that are supposed to insert data into a table, on a database that's been pre-selected in the variable $GLOBALS['mysqli']. The connection has been tested, and that's not the problem I'm having. I'm only running into trouble whenever my prepared statement involves INSERT INTO. I know the tablename, and field names are correct, but $stmt is ALWAYS false. What gives? $stmt = $GLOBALS['mysqli']->prepare("INSERT INTO audit_RefreshCount (user, count, lastrefresh) values (?,?,?)"); if ($stmt == TRUE) { $stmt->bindParam('ssi', $_SESSION['username'], '0', time()); //$stmt->bind_Param('ssi', $_SESSION['username'], '0', time()); // Also doesn't work. $stmt->execute(); }

• Flex: client / server messaging question (RPC or socket ?)

  - by Patrick

  hi, I'm building a Flex application, which is going to perform many server requests (let's say, that almost all interactions require an update from server). At the moment I'm using remote procedure calls for it. But I was wondering if using a socket would be better. In other terms, is maybe better to keep the connection alive rather then performing many calls in sequence ? For my demo app I only have 1 client. Is the number of clients connecting to the server a factor for this choice ? thanks

• How to create initializeDB() method for java database

I can't find much on the initializeDB() method, but if I could get some help I would really appreciate it.
