I could create a jar file and deploy my session bean using Structure Builder and Deployment Builder.So I am fine for the time being,but I would still like to know what is wrong with ejbdeployer or my deployment,whichever is the case.I am posting the method signatures of remote,home and bean:
UserAdminSession:
package com.sam.session; import javax.ejb.EJBObject; import java.rmi.RemoteException; import java.util.Vector; import com.sam.utility.*; import com.sam.helper.*; import com.sam.session.*; public interface UserAdminSession extends EJBObject { public boolean createRoles(RolesInfo rolesInfo) throws RemoteException; public RolesInfo readRoles(long ro_roleid) throws RemoteException; public boolean updateRoles(RolesInfo rolesInfo) throws RemoteException; }
UserAdminSessionHome:
package com.sam.session; import javax.ejb.EJBHome; import javax.ejb.CreateException; import java.rmi.RemoteException; import com.sam.session.*; public interface UserAdminSessionHome extends javax.ejb.EJBHome { /** * @return */ public UserAdminSession create() throws CreateException, RemoteException; }
UserAdminSessionBean:
package com.sam.session; import java.sql.*; import java.rmi.*; import javax.ejb.*; import javax.transaction.*; import javax.naming.*; import java.util.*; import java.io.*; import com.sam.utility.*; import com.sam.helper.*; import com.sam.admin.*; import com.sam.session.*; /** * @stereotype SessionBean * @statemode Stateless * @homeInterface com.sam.session.UserAdminSessionHome * @remoteInterface com.sam.session.UserAdminSession */ public class UserAdminSessionBean implements SessionBean { private SessionContext context; protected Context initial; private RolesHome rolesHome; //Roles is an entity bean private Roles roles; private RolesPK rolesPK; private String rolesSeqName = null; private long ro_roleid; /** * Sets the context of the bean * @param context The Bean's Context */ public void setSessionContext(SessionContext context) { this.context = context; try { Context initial=new InitialContext(); rolesSeqName = (String) initial.lookup("java:comp/env/RolesSeqName"); Object objRoles = initial.lookup("java:comp/env/ejb/RolesHome"); System.out.println("setSessionContext: Look up for Roles ok"); rolesHome = (RolesHome)javax.rmi.PortableRemoteObject.narrow(objRoles,RolesHome.class); System.out.println("setSessionContext: narrowing for Roles ok"); } catch(Exception ex) { System.out.println("setSessionContext: exception "+ex.getMessage()); ex.printStackTrace(); } } /** * This method is called when the container picks this session object * and assigns it to a specific session object. Insert code here to * acquire any additional resources that it needs when it is in the * ready state. */ public void ejbActivate() { } /** * This method is called when the container diassociates the bean * from the session object identity and puts the instance back into * the pool of available instances. Insert code to release any * resources that should not be held while the instance is in the * pool. */ public void ejbPassivate() { } /** * This method is invoked when a client invokes the matching create() * on the home interface. */ public void ejbCreate() { } /** * The container invokes this method in response to a client-invoked * remove request.

Hi,
I am getting the following exception when I try to create a jar file for a session bean.I have created around 10 entity bean jar files using ejbdeployer tool and everything worked fine.They were also deployed without any error.Now suddenly when I try to do the same thing for session bean it throws me this exception.I am confused!!
The 3 classes(remote+bean+home) for the session bean are located in package structure like com.sam.session.I use a helper class which is in com.sam.helper.
I am using weblogic 5.1(evaluation copy) and structurebuilder to develop the beans(both entity and session).
I would appreciate any help from this forum.I know somebody else has also posted similar question but there is no reply in it.

Thanks for the input Carl.Its working fine now and I can insert records in the database.

I have to insert a date in the database(oracle 8).I am using following peice of code:
if(info.getLastUpdatedTime() == null )
{
System.out.println("if:UPDTime in ejbcreate oucbean....");
pstmt.setDate(7,date);//date is defined as java.sql.Date
}
else
{
System.out.println("else:UPDTime in ejbcreate oucbean....");
pstmt.setDate(7,info.getLastUpdatedTime());
}
The method getLastUpdatedTime() is defined to return a a java.util.Date.But I have to convert it to java.sql.Date before I issue an insert sql statement.
Can anybody give me a peice of code that converts java.util.Date to java.sql.Date.
(weblogic 5.1.0
oracle 8)

Thanks for the inputs.I did download the latest service pack ,but before that I reset my classpath and weblogic.class.path using wlconfig.exe command in weblogic/bin and it worked!!So I wont install the service pack.Thanks again

(I had to change my userid,looks like it doesnt follow the norms of the site)
My CLASSPATH is set as follows:
(everything is installed in d drive and development\work\classes in classpath is the package where i am working ie d:\development\work\classes\com\xxxx\....)

d:\weblogic\classes;d:\weblogic\lib\weblogicaux.jar;
d:\weblogic\license;d:\weblogic\classes\boot;
d:\weblogic\myserver\clientclasses;
d:\weblogic\myserver\serverclasses weblogic.server;
d:\weblogic\lib\rmiForMs.zip;d:\jdk1.2.2\lib\tools.jar;
d:\jdk1.2.2\lib\classes.zip;
d:\development\work\classes
I dont have any weblogic class path explicitly set.As far as I know only CLASSPATH settings would be enough to run applications.
Also I have created the jar files using the 'build' file that comes with weblogic examples.The deployertool was not working for some reason.I have an evaluation copy right now.
