Weblogic11gでJava6を実行しています。
私は、EJBを使用してデータベースと通信するWebサービスプロジェクトに取り組んでいます。現在、エラー処理に取り組んでいるため、Webサービスを呼び出す前にEJBをアンデプロイしてみました。私のEJBClientHelperクラスは次のようになります。
package mypackage.elkom.utils;
import java.io.Serializable;
import java.util.Properties;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import mypackage.elkom.ejb.beans.session.remote.ElkomRemote;
public class EJBClientHelper implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;
private ElkomRemote elkomRemote;
private static final String ELKOM_JNDI = "ElkomBean#mypackage.ejb.beans.session.remote.ElkomRemote";
private Context ctx;
private void prepareEjb3Connection() throws PropsFileException, NamingException {
// Here's code for getting the ejbProviderURL from propsfile //
props.put("java.naming.factory.initial", weblogic.jndi.WLInitialContextFactory");
props.put("java.naming.provider.url",ejbProviderURL);
ctx = new InitialContext(props);
}
public void setElkomRemote(ElkomRemote elkomRemote) {
this.elkomRemote = elkomRemote;
}
public ElkomRemote getElkomRemote() throws NamingException, PropsFileException {
prepareEjb3Connection();
if(elkomRemote == null) {
elkomRemote = (ElkomRemote)ctx.lookup(ELKOM_JNDI);
}
return elkomRemote;
}
}
しかし、getElkomRemote();を使用すると 私はNamingExceptionの代わりにこのメッセージを受け取ります:
SEVERE: The object identified by: '678' could not be found. Either it was has not been exported or it has been collected by the distributed garbage collector.;
nested exception is: java.rmi.NoSuchObjectException: The object identified by: '678' could not be found.

NamingExceptionの代わりにこのメッセージが表示される理由を知っている人はいますか?そして、おそらくそれを修正する方法は?
