constructor exception (Error: WSE 99999) error while creating web session

Hi all,

I am working on business objects with Java web sdk on XI R3 version. When I am trying to create a web session with  code like

                      URL objURLSession =new URL("http://boserver:port/dswsbobje/services/Session");          

     Connection objConnection = new Connection(objURLSession);

     Session objSession = new Session(objConnection );

     EnterpriseCredential objEnterpriseCredential = EnterpriseCredential.Factory.newInstance();

     objEnterpriseCredential.setLogin(UserName);

     objEnterpriseCredential.setPassword(sPassword);

     objEnterpriseCredential.setDomain(sCMSName);

     SessionInfo objSessionInfo = objSession.login(objEnterpriseCredential);     

     String strSessionID = objSession.getConnectionState().getSessionID();

I am getting error on the third line Session objSession = new Session(objConnection ); while creating session.

org.apache.axis2.AxisFault: constructor exception (Error: WSE 99999)

     at com.businessobjects.webservice.BOCustomSecurity.boSessiontest(BOCustomSecurity.java:58)

     at com.businessobjects.webservice.TokenWebservice.main(TokenWebservice.java:283)

I am using Eclipse for developing this application. I am unable to create a web session in .net as well with Java enterprise SDK.

Can anybody help me in creating java web session?

Thanks in advance,
