Hi

i tried to test my Entity Bean by the Universal Test Client in Websphere 5.1 but i got errors when i execute the findByPlatform() , pls tell me what's the problem ?

the source code of localhome interface :
============================================

package apress.wsad.techlib;

import java.util.Collection;

/**
* Local Home interface for Enterprise Bean: Book_catalog
*/
public interface TechLibBook_catalogLocalHome extends javax.ejb.EJBLocalHome {
/**
* Creates an instance from a key for Entity Bean: Book_catalog
*/
public apress.wsad.techlib.TechLibBook_catalogLocal create(java.lang.String catalog_number)
throws javax.ejb.CreateException;
/**
* Finds an instance using a key for Entity Bean: Book_catalog
*/
public apress.wsad.techlib.TechLibBook_catalogLocal findByPrimaryKey(
apress.wsad.techlib.TechLibBook_catalogKey primaryKey)
throws javax.ejb.FinderException;
/**
* Creates an instance from a key for Entity Bean: Book_catalog
*/
public apress.wsad.techlib.TechLibBook_catalogLocal create(
java.lang.String catalog_number,
java.lang.String author,
java.lang.String book_title,
java.lang.String location,
java.lang.String platform,
java.lang.String language)
throws javax.ejb.CreateException;

public Collection findAll() throws javax.ejb.FinderException;
public Collection findByPlatform(java.lang.String workPlatform) throws javax.ejb.FinderException;
}

the errors that i got it when execute findByPlatform():

hi,

i am just playing around with WSAD these days, i beleive i have come across this error when i tried my Entity bean.. were you using the default Cloudscape DB for your entity bean ? My suggestion is start all over , create a new EAR, EJB and Server..i spend alot of time trying to solve the issue, no-one was replying to the messages i posted. I just did the whole process again and it worked fine..

thanks,
Rajeev.
