Problem in deplyoing Struts - Hibernate project

saumesh_kumar Mar 25, 2008 5:39 AM

Hello...

I am working on struts & hibernate 3 & using websphere as IDE. The project is working fine in Websphere & tomcat, but when I deploy it to JBoss 4.0.3 SP1, there are lot of problems.

When I run sql query through

session.createSqlQuery()

it says that

addScalar() or addEntity() methods

must be executed before executing query.

other problem is that when I run HQL through

session.cerateQuery()

. It says that

no persistent classes found for query class: select us.strEmpId, us.strUserName

and throws following exception -

[org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/DHBVN].[action]] Servlet.service() for servlet action threw exception
java.lang.NullPointerException
