    Connection problem Jboss 3.0 to Oracle 8i

    irfan_a Newbie

      I am new to jboss, working on deploying and running a small test application using Jboss 3.0 and Oracle 8i. It simply consists of one session bean and a client class to test session bean. I have copied the classes12.zip file in %JBOSSHOME%\server\default\lib and appropriately edited oracle-service.xml, login-config.xml files for my Oracle database. The session bean (named Contact) creates an instance of dataSource and attempts to create a connection with following function call:

      con = dataSource.getConnection();

      This results in following error:

      20:46:03,513 INFO [STDOUT] SQLException: Could not create connection; - nested
      throwable: (java.sql.SQLException: invalid arguments in call); - nested throwabl
      e: (org.jboss.resource.JBossResourceException: Could not create connection; - ne
      sted throwable: (java.sql.SQLException: invalid arguments in call)):null
      20:46:03,523 INFO [STDOUT] from ContactBean

      In desperation, I tried to connect with following call and it worked
      con = dataSource.getConnection(username, password);

      I am not using jboss.xml because i have read somewhere that this file is not required unless there is vendor specific configuration.

      I am using following (ejb-jar.xml) descriptor for the session bean

      <?xml version="1.0" encoding="UTF-8"?>

      <ejb-jar>
      Simple application
      <display-name>Data Access Application</display-name>
      <enterprise-beans>

      <ejb-name>Contact</ejb-name>
      com.javapro.ejb.ContactHome
      com.javapro.ejb.Contact
      <ejb-class>com.javapro.ejb.ContactBean</ejb-class>
      <session-type>Stateless</session-type>
      <transaction-type>Bean</transaction-type>

      </enterprise-beans>
      </ejb-jar>

      I would appreciate if any one can give me some clues why my connection is not established without passing username and password as parameters.

      Thanks,
      Irfan
