howto session bean w/ XDoclet

[Willian Irving Zumwalt]

Hey all,

Does anyone see anything wrong w/ this session bean. I'm pretty new to
XDoclet and having various problems in compiling or loading. So now
I'm just trying a very basic example. I get the following compile
errors below it.

/**
*
* @ejb.bean
* name="comp/History"
* type="Stateless"
* view-type="remote"
* jndi-name="ejb/comp/History"
*
* @ejb.home
* extends="javax.ejb.EJBHome"
* remote-class="com.place.management.ejb.session.HistoryHome"
*
* @ejb.interface
* extends="javax.ejb.EJBObject"
* remote-class="com.place.management.ejb.session.History"
*/

public class HistoryBean implements SessionBean
{
private transient SessionContext context = null;

public void setSessionContext(SessionContext ctx) {
context = ctx;
}

public void unsetSessionContext() throws EJBException {
context = null;
}

/**
* @ejb.create-method
*/

public void ejbCreate() throws CreateException { }

/**
* @ejb.home-method
*/

public void ejbRemove() throws EJBException { }

/**
* @ejb.home-method
*/

public void ejbPassivate() { }

/**
* @ejb.home-method
*/

public void ejbActivate() { }

/**
* @ejb.home-method
*/

public void ejbRemove() { }
}

First definition.

public void ejbPassivate() { }

/**

*/

public void ejbActivate() { }

/**
* @ejb.home-method

public void ejbRemove() { }

Second definition.

}

Remove one.

Apologies, just got really tired working on these probs. I've posted the
real error output below and removed that typo of multiple declarations
of remove().
