Find failed: This method is not yet implemented.

Hi all,

I am encountering an error with a CMP 2.0 finder method that I cannot track down and I am hoping someone can shed some light on it.

I have defined a simple finder method in a CMP 2.0 entity bean as follows:

a) Local Home Interface Snippet
================================
public interface SecurityActionHomeLocal extends EJBLocalHome
{
public SecurityActionLocal findByName (String name) throws FinderException;
}

b) ejb-jar.xml Snippet
=======================

This bean represents a Struts Action Mapping.
<ejb-name>SecurityActionEJB</ejb-name>
<local-home>ca.talonline.business.security.action.SecurityActionHomeLocal</local-home>
ca.talonline.business.security.action.SecurityActionLocal
<ejb-class>ca.talonline.business.security.action.SecurityActionEJB</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.Integer</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>SecurityAction</abstract-schema-name>
<cmp-field>
<field-name>id</field-name>
</cmp-field>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<cmp-field>
<field-name>description</field-name>
</cmp-field>
<primkey-field>id</primkey-field>
<security-identity><use-caller-identity /></security-identity>

<query-method>
<method-name>findByName</method-name>
<method-params>
<method-param>java.lang.String</method-param>
</method-params>
</query-method>
<ejb-ql>
SELECT OBJECT (sa)
FROM SecurityAction AS sa
WHERE sa.name = ?1
</ejb-ql>

<query-method>
<method-name>findAll</method-name>
<method-params />
</query-method>
<ejb-ql>
SELECT OBJECT (sa)
FROM SecurityAction AS sa
</ejb-ql>

c) jboss.xml Snippet
=====================

<enterprise-beans>

<ejb-name>SecurityActionEJB</ejb-name>
<configuration-name>Standard CMP 2.x EntityBean</configuration-name>

</enterprise-beans>

d) jbosscmp-jdbc.xml Snippet
============================
<jbosscmp-jdbc>
<enterprise-beans>

<ejb-name>SecurityActionEJB</ejb-name>
<table-name>Account</table-name>
<cmp-field>
<field-name>id</field-name>
<column-name>id</column-name>
<not-null />
</cmp-field>
<cmp-field>
<field-name>name</field-name>
<column-name>name</column-name>
<not-null />
</cmp-field>
<cmp-field>
<field-name>description</field-name>
<column-name>description</column-name>
</cmp-field>

</enterprise-beans>
</jbosscmp-jdbc>

I hope it is alright not to include the relationship fields -- I wasn't sure if I needed to post them here for this example.

Anyway, the code compiles. When I attempt to access the method from another EJB, however, I get the following error:

etc...

Can anybody tells me what this message means ("This method is not yet implemented.")? Searches on jboss.org and Google don't pull anything up on it and it's got me perplexed.

Thanks,
Darryl

Oh, I forgot...I am running JBoss 3.0.4 / Tomcat 4.1.12 (?) and am running the CMP against a PostgreSQL 7.x database.

Hmm, no luck yet but I have determined that the error message is not JBoss but PostgreSQL related. My driver's up to date, the connection is established (otherwise the error wouldn't have been propogated up to me.) Any suggestions appreciated :-)

Hi again,

I did some checking in the PostgreSQL logs and found that the EJB-QL query:

SELECT OBJECT (sa)
FROM SecurityAction AS sa
WHERE sa.name = ?1

is being sent to the PostgreSQL database as:

SELECT typlen
FROM pg_type
WHERE typname='name'

Does anyone know why this may be happening? Is this a CMP bug? A problem with my deployment descriptor?

Thanks,
Darryl

Hi all,

I've tracked the problem down. It turns out that my ejb-jar.xml file was not well formed. In some of my entities, I had children tags defined in the following order:

<resource-ref>
<ejb-local-ref>
<security-identity>

when I should have defined them in the following order:

<ejb-local-ref>
<security-identity>
<resource-ref>

Once I modify my ejb-jar.xml file to reflect these changes, my CMP find methods started working.

Phew. This is a whole new category of error for me :-)

Have a good weekend.

darryl_staflund Jan 24, 2003 6:46 PM (in response to darryl_staflund)

Hi all,

I found a fix. It turns out that some elements in my ejb-jar.xml deployment descriptor were defined in the wrong order. When I moved them around to conform to the ejb-jar 2.0 DTD, the CMP file methods ran fine.

Have a good weekend.
