problem passivating SFSB

asookazian Apr 16, 2008 4:47 PM

I have a Seam2.0.0.GA app with JBoss4.2.1.GA. This particular SFSB has the following instance variables defined and I added a @PrePassivate callback handler method to close and null out JDBC related objects, etc.

What are you supposed to do with List objects that are not serializable??

SFSB partial code:

@Stateful
//AS 041508 - testing session scope for conversation ended error
@Scope(ScopeType.SESSION)
@Name("techDeployToUser")
public class TechDeployToUserAction implements TechDeployToUserLocal{

 @Logger
 Log log; //externalizable (according to Pete Muir) which implements serializable

 @In
 private FacesMessages facesMessages; //serializable

 @In
 Identity identity; //serializable

 @In (required=false)
 UTbUser user; //serializable

 @In
 Context sessionContext; //not serializable

 private List<TbHardwareObject> hardwareTableList = new ArrayList(); //not serializable
 private List<TbHardwareObject> locationsList = new ArrayList(); //not serializable
 private List<TbHardwareObject> userLocEquipList = new ArrayList(); //not serializable
 private List<TbHardwareObject> newlyAssignedByTechEquipList= new ArrayList(); //not serializable
 private List<TbHardwareObject> removedFromUserEquipList = new ArrayList(); //not serializable

 Connection con = null; //not serializable
 Statement stmt = null; //not serializable
 PreparedStatement preparedStmt = null; //not serializable
 ResultSet rs = null; //not serializable
 StringBuffer sqlStringBuffer = null; //serializable

 List assignedToTechHardwareList = new ArrayList(); //not serializable
 String locNo; //serializable
 String techLocMsg = ""; //serializable
 String userLocMsg = SHIMSConstants.USER_MSG; //serializable

 String month="", day="", year="", localAssignedDate=""; //serializable
 Map params; //not serializable

 String msgConfirm; //serializable
 String compId; //serializable
 String compMsg; //serializable
 String techLocationName; //serializable
 String userLocationName; //serializable
 String networkLogin; //serializable

 boolean isAssignToTechBtn = true; // n/a
 boolean isSubmitByTechBtn = true; // n/a

 Date now = new Date(); //serializable
 TbLocationEntityDAO tbLocationDAO = null; //not serializable
 TbHardwareObject tbHardwareObject = null; //not serializable
...
}

more partial code:

 @PrePassivate
 private void cleanupBeforePassivation() {
 log.info("inside cleanupBeforePassivation()");
 cleanUp();
 con = null;
 stmt = null;
 preparedStmt = null;
 rs = null;
 }

partial stack trace:

1. Re: problem passivating SFSB

asookazian Apr 16, 2008 4:48 PM (in response to asookazian)

what are the repurcussions or problems of a failed passivation?? how will it affect the next use case execution?

2. Re: problem passivating SFSB

asookazian Apr 16, 2008 7:24 PM (in response to asookazian)

Problem resolved by setting an additional instance variable to null in the @PrePassivate method:

private void cleanUp()
 {
 try
 {
 if (rs != null)
 {
 rs.close();
 }
 if (preparedStmt != null)
 {
 preparedStmt.close();
 }
 if (stmt != null)
 {
 stmt.close();
 }
 if (con != null)
 {
 con.close();
 }

 }
 catch(SQLException e) {
 e.printStackTrace();
 }
 }

@PrePassivate
 private void cleanupBeforePassivation() {

 cleanUp();
 con = null;
 stmt = null;
 preparedStmt = null;
 rs = null;

 params = null; //<-- root cause identified! at least this variable not being set to null causes the
 // javax.ejb.EJBException: Could not passivate; failed to save state error...
 }

Alternative fix is to not use the Map params variable as an instance variable, but as multiple local instances.

The stack trace is very misleading:

Caused by: java.lang.NoClassDefFoundError: org/jaxen/VariableContext

when that class is actually residing in the JBOSS_HOME/server/default/lib/jaxen.jar...
