Create exception
arnaud74130 Dec 6, 2001 5:47 AMhi,
I can't create my EJB 1.1 with JBoss 2.4.1 / Tomcat
i just have a simple Entity:
when i call the create method, i still have
" javax.ejb.CreateException: Could not create entity:java.lang.NullPointerException
at org.jboss.ejb.plugins.jaws.jdbc.JDBCCreateEntityCommand.execute(JDBCCreateEntityCommand.java:139)"
i try different create method (with parameters ect..)
but each time i have the same error.
My Datasource is ok, and the tables are automatically created by JBoss, so it is "JUST" an entity creation problem,
please help.
