I am getting the 'NoManagedConnections' Exception this only happens after a while, but I confess I am confused by the JBoss documentation and the few examples of servlets working with JBoss don't seem to be much help.
I get a new connection object when I call the init method of each of my servlets (there are about 20), that is the only connection object I use for that servlet (I pass it as a parameter to the various factory classes I use within the servlet to do database access). But if I understand correctly, there is only one instance of each servlet - so it shoud only be using one connection? So I should only be using the same number of connections as servlets? Do I really need to close and create connections whenever I use JDBC? Is there somewhere I can put a close command that wouldn't be too much rework? Or is there a timeout for spotting dead connections? I already have a fairly large application and this would be painful to put it mildly... I thought that was the point of a managed connection pool? I have included the datasource XML file and also the code for getting a connection. Thank-you in advance Mark I have project-ds.xml file to set-up a connection pool with Postgres: | <datasources> | <local-tx-datasource> | <jndi-name>MtrdbDS</jndi-name> | <connection-url>jdbc:postgresql://myserver:5434/myDb</connection-url> | <driver-class>org.postgresql.Driver</driver-class> | <user-name>someUser</user-name> | <password>somepassword</password> | <metadata> | <type-mapping>PostgreSQL 8.0</type-mapping> | </metadata> | </local-tx-datasource> | I use a JNDI call to get a connection from that pool: | public Connection getConnection() throws SQLException | { | Connection conn = null; | Context ctx = null; | DataSource ds = null; | String sourceName = ""; | | try | { | ctx = new InitialContext(); | | if(ctx == null ) | throw new NamingException("Error 'Db.getConnection' - No Context"); | | sourceName = this.getDbName(ctx); | | ds = (DataSource)ctx.lookup(sourceName); | } | catch (NamingException e) | { | MtrErr.writeExc(MtrErr.OTHER_SOURCE,this.getClass().toString(),"getConnection",e); | } | catch (Exception e) | { | MtrErr.writeExc(MtrErr.OTHER_SOURCE,this.getClass().toString(),"getConnection",e); | } | | if (ds != null) | { | conn = ds.getConnection(); | } | | return(conn); | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3957921#3957921 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3957921 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
