sorry for posting ist twice, it was a mistake
I know nothing about pointbase, but this is the kind of error occurs when for some reason JBoss couldn't get a connection from the database.
Check the username and password. If pointbase has host-based access control, check if the host where JBoss is running has access. Try to obtain a connection from a sample program or from any other JDBC based program. Make sure your database is in order.
thanks for your answer
i did what you suggested, i wrote a simple jdbc programm, and my database is working. my password and username are both set. pointbase and jboss are running on the same machine.
do you have an other idea of what could be the problem?
I'm not 100% certain, but you might try using the XA DataSource that ships with Pointbase (com.pointbase.xa.xaDataSource).
Also, the following is cut and pasted directly from the Pointbase Developer documentation:
To successfully run your XA application with PointBase, you must obtain the following two JAR files from the Sun Microsystem?s website, ?jta.jar? and ?jdbc2_0-stdext.jar? and, include them in your classpath with the PointBase JAR?s.
? Download the ?jta.jar ?at http://java.sun.com/products/jta/index.html
? Download the ?jdbc2_0-stdext.jar? at http://java.sun.com/products/jdbc/
Hope that helps.
