Ejb interface problem on websphere 4

Hi,

I am new to Spring. i am using Spring to manage EJB connection. it is working fine on the WSAD environment. but when I deploy the ejb to websphere, I got this error message,

Error 500: Error creating bean with name 'SQLAction' defined in file [C:\WINNT\system32\beans.xml]: Error setting property values; nested exception is org.springframework.beans.PropertyAccessExceptions Exception: PropertyAccessExceptionsException (1 errors); nested propertyAccessExceptions are: [org.springframework.beans.TypeMismatchException: Failed to convert property value of type [com.net.gcms.ejb._SQLRunnerHome_Stub] to required type [com.net.gcms.ejb.SQLRunnerHome] for property 'service']


Any idea?

Thank you in advance.

If com.net.gcms.ejb._SQLRunnerHome_Stub does implement com.net.gcms.ejb.SQLRunnerHome, then my guess would be on a ClassLoader issue. That somehow, com.net.gcms.ejb.SQLRunnerHome is available twice on your classpaths, and that spring has a different jar than your EJB uses.

gpoirier, thank you for your help.
