ejbSelect generates NPE

[sbm5c2j8]

ejbSelect method generates NullPointerException. The same logic for finder method appears working OK.

Environment:
JBOSS 3.0 (from CVS a few days ago)
Windows 2000

in ejb-jar.xml

<query-method>
<method-name>ejbSelectValuesBetween</method-name>
<method-params>
<method-param>java.lang.Integer</method-param>
<method-param>java.lang.Integer</method-param>
</method-params>
</query-method>
<ejb-ql>
<![CDATA[SELECT OBJECT(o)
FROM TestA1 AS o
WHERE o.id BETWEEN ?1 AND ?2
]]>
</ejb-ql>


In EntityBean implementation
abstract public Collection ejbSelectValuesBetween(Integer id1, Integer id2)
throws FinderException;

public void myMethod(...)
{
Collection c = ejbSelectValuesBetween(id1, id2)
..
}

It looks like you're trying to call the select method from a home method. If so this currently doesn't work correctly in 3.0alpha (at least as of 1/10/02). Select methods work and home methods work, but you can't call a select method from within the home method. I talked to Dain about it and he said he would fix it. I You can check out the bug report on sourceforge.

[sbm5c2j8]

Thank you, I was calling ejbSelect from EJB home method.

[jcarroll]

Dain closed the bug report last night so you might try getting the latest cvs code and seeing if your stuff works now.

Dain thanks again for your help.

[sbm5c2j8]

Thank you for your reply. I tried from CVS today (Jan 31) and now I am getting the following error.
This worked in the earlier version except NPE from Home method.

Thanks

mytest.ear consists of

META-INF/application.xml
lib/mylib.jar -> this is utility class
myentity.jar -> entity beans with CMR
mytest.jar -> session beans
mytest.war -> web application

[sbm5c2j8]

It works fine from today's CVS (Feb 4).

Thanks.

[sbm5c2j8]

WOW!!! I didn't realize jbosscmp-jdbc_3_0.dtd was changed. Once I revised jbosscmp-jdbc.xml for the change, all my test case seems working now. Excellent work. Thanks lot.

[bongosdude]

can you show me what files needs to get from pvcs to fix this problems?

[bongosdude]

Do you have a bug id? I do not know how to query bug database and figure out what files I need to get to have this bug fixes? Does this fix in 3.0.6, 3.2.0? 4.0?

I need to call ejbselect from my home. pls help.
