Hello,
Any help or suggestion is greatly appreciated.
I have a remote interface called UserControllerRemoteHome that contains a method named
validateUserPassword that return a java Serializable object. The client is a Servlet
that deployed in a standalone Tomcat version 4.1.30. The Tomcat is running in the same
server as Jboss 3.2.1. The servlet accesses the remote ejb with the following code:
| UserControllerRemoteHome homeObject;
| String remoteJndiName = "UserControllerBeanJNDI";
| homeObject = (UserControllerRemoteHome) homesFactory.lookUpHome(remoteJndiName,
UserControllerRemoteHome.class);
| // get the EJBObject, UserControllerRemote
| UserControllerRemote ejbObject = homeObject.create();
|
| // Now problem so far up to this point, but an Exception occurred when
| // the validateUserPassword method returned a java serializable object
BasicUserInformationDO,
| // however; when the validateUserPassword returned null then no exception occurred.
| // The log file producted by jboss server.log does not show any exception at all
| BasicUserInformationDO basicUserInfoDO = null;
| try {
| basicUserInfoDO = (BasicUserInformationDO)
| ejbObject.validateUserPassword(
Integer.parseInt(userID),
|
Short.parseShort(subID),
| password,
sessionID);
| } catch (IOException ioEx) {
| request.getSession().getServletContext().log("IOException",
| new Throwable(ioEx.toString()));
| } catch (ServletException servletEx) {
| request.getSession().getServletContext().log("Servlet Exception",
| new Throwable(servletEx.toString()));
| }
| } catch (RemoteException remoteEx) {
| request.getSession().getServletContext().log("Remote Exception",
| new Throwable(remoteEx.toString()));
| } catch (CreateException createEx) {
| request.getSession().getServletContext().log("create Exception",
| new Throwable(createEx.toString()));
| } catch (IOException ioEx) {
| request.getSession().getServletContext().log("IOException",
| new Throwable(ioEx.toString()));
| } catch (Exception Ex) {
| request.getSession().getServletContext().log("Exception",
| new Throwable(Ex.toString()));
| }
****** Here is the method that returns the serializable object ********
| public BasicUserInformationDO validateUserPassword(int userID, short subID,
| String password, String sessioID)
| {
|
| BasicUserInformationDO basicUserInfoDO = null;
| // To valid the password we need to access the UserBean (ejb-name). However,
we also
| // to return the BasicUserInformationDO object, thus we need to access the
| // UserAccountBean (ejb-name). So we need toltal of two references to fulfill
this
| // mission.
| // Get a UserBean's home object from the EJBLocalHomeFactory
| try {
| // get an instance of the UserEjbUtil
| UserEjbUtil userBeanUtil = UserEjbUtil.getInstance();
|
| // get the EJBObject, UserLocal
| UserLocal userObject =
userBeanUtil.getUser(StringUtilities.getPrimaryKey(userID, subID));
|
| if (userObject != null) {
| // Now we check the password from the user input against the password from
the database
|
| // get the EJBObject, UserAccountLocal
| UserAccountEjbUtil userAccountBeanUtil =
UserAccountEjbUtil.getInstance();
|
| UserAccountLocal userAccountObject = userAccountBeanUtil.getUserAccount(
|
StringUtilities.getPrimaryKey(userID, subID));
|
| if (userAccountObject != null) {
| // Now get the serviceTypesSubscribed and numberOfServicesSubscribed
from the UserAccountBean
| basicUserInfoDO = new
BasicUserInformationDO(userObject.getFirstName(), userObject.getLastName(),
|
| userObject.getMiddleName(), userID,
subID,
|
userAccountObject.getNumberOfServicesSubscribed(),
|
userAccountObject.getServiceTypesSubscribed());
| if (log.isDebugEnabled()) {
| log.debug(basicUserInfoDO.toString());
| }
| }//End if userAccountObject
| }//End if
| }//End if userObject
| } catch (IOException ioEx) {
| log.debug("IOException" +
ExPrintingUtilities.PrintStackTraceElements(ioEx.getStackTrace()));
| } catch (Exception Ex) {
| log.debug("Exception" +
ExPrintingUtilities.PrintStackTraceElements(Ex.getStackTrace()));
| } catch (Throwable throwableEx) {
| log.debug("Throwable" +
ExPrintingUtilities.PrintStackTraceElements(throwableEx.getStackTrace()));
| }
|
| if (log.isDebugEnabled()) {
| log.debug("End validateUserPassword");
| }
| return basicUserInfoDO;
| } /* End validateUserPassword method */
Thank you in advance for your help.
