Let me reiterate because it is still an issue:
Everything till now works fine, iBatis / JBoss / Struts - DataSource
This is a struts app where I am doing an asynch JavaScript call to a
Servlet where I do some work. Consume a WebService and Delete a database
record.
I get the NPE.....
Caused by: java.lang.NullPointerException
at
com.ibatis.dao.engine.impl.StandardDaoManager.getTransaction(StandardDaoManager.java:108)
at
com.ibatis.dao.client.template.SqlMapDaoTemplate.getSqlMapExecutor(SqlMapDaoTemplate.java:60)
at
com.ibatis.dao.client.template.SqlMapDaoTemplate.delete(SqlMapDaoTemplate.java:142)
at
gov.gsa.base.dao.SqlMapDaoTemplateWrapper.delete(SqlMapDaoTemplateWrapper.java:41)
... 25 more
gov.gsa.base.exception.DAOException : java.lang.NullPointerException
- I have a theory that iBatis cant load the SQLMap because it is a
different ServletContext than struts... I can neither support or disprve
this claim...Help? Ideas?
TIA
Well, bcak to it:
<CODE>
//TEST
DataSource dataSource = null;
try{
Context initContext = new InitialContext();
dataSource = (DataSource)
initContext.lookup("java:REALNAME");
} catch (NamingException ne){
ne.printStackTrace();
System.out.println(" NamingException: " +
ne.getMessage());
}
System.out.println(" dataSource: " + dataSource);
</CODE>
This test returns : 2007-08-21 15:08:25,852 INFO [STDOUT] dataSource:
[EMAIL PROTECTED]
So I got that goin' for me.....
Still get the NPE.....

Ack, I hate NPEs, they're so embarrassing. iBATIS should never throw
one.
Once we find out why it does in this case, we'll fix it.
The most likely source is this: "java:DATASOURCE"
Make sure this works in your environment:
DataSource dataSource = (DataSource)
initCtx.lookup("java:DATASOURCE");

Well, that looks ok.
Could the transaction be closed or committed early, before the delete?
