Hi All-
I have been searching for days to the solution to this problem- to no avail. I have a
finder method: findByName(String name) and the requisite findByPrimaryKey(Integer key)
methods in my home interface. The find by pk method works fine, the findByName does
not. In the jboss log, I see sql being fired off for the find by pk, but not for the
findByName method. It seems like jboss is not picking up the ejb-ql, even though it
complains if I take the <ejb-ql> line out of the .
I have created the required entries in my ejb-jar.xml and even made sure jboss was
reading it by putting in bad xml to see if jboss generated errors which it did. I
tried copying the same code into a META-INF\jbosscmp-jdbc.xml file and that didn't
work either. Here are the code slices:
public interface EntityTypeHome extends javax.ejb.EJBHome
{
public EntityType create(String type_name)
throws CreateException, RemoteException;
public Collection findByName(String type_name)
throws FinderException, RemoteException;
public EntityType findByPrimaryKey(Integer type_code)
throws FinderException, RemoteException;
}
ejb-jar.xml:
<?xml version="1.0"?>
<!DOCTYPE ejb-jar PUBLIC "-//Sun Microsystems, Inc.//DTD Enterprise JavaBeans 1.1//EN"
"http://java.sun.com/j2ee/dtds/ejb-jar_1_1.dtd";>
<ejb-jar>

<query-method>
<method-name>findByName</method-name>

<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>SELECT OBJECT(o) FROM entitytype AS o WHERE o.type_name = ?1></ejb-ql>
</enterprise-beans>
<assembly-descriptor>
<security-role>
This role represents everyone who is allowed full access
to the Entity Type bean.
<role-name>everyone</role-name>
</security-role>
<method-permission>
<role-name>everyone</role-name>
<ejb-name>Entity_Type</ejb-name>
<method-name>*</method-name>
</method-permission>
<container-transaction>
All methods require a transaction
<ejb-name>Entity_Type</ejb-name>
<method-name>*</method-name>
<trans-attribute>Required</trans-attribute>
</container-transaction>
</assembly-descriptor>
</ejb-jar>
I took out the jbosscmp-jdbc.xml file from the jar again, as from my (extensive!)
research into this problem, it has become apparent that JBoss should be able to read
the ejb-ql from my ejb-jar.xml file anyway. If I am mistaken in this let me know- but
this thing still didn't work, even with it in there.
Any help is greatly appreciated, I'll buy the beer on Friday!!! ;0)
Dan
