We are getting the following error in our clustered QA environment. We run Weblogic 10.3.3.0 on linux.

Any suggestions on what might cause this?

Hi Thenrik,
This is right but Serialization does not concern about methods. and it is only about Instance variables.
public static TreeMap<Job, Integer> getJobListforCompany(Connection tjfConn, int companyID, StringBuffer message) {
           TreeMap<Job, Integer> jobsList = new TreeMap<Job, Integer>(new Comparator() {
                public int compare(Object job, Object anotherJob) {
                     String name1 = ((Job) job).getName();
                     String name2 = ((Job) anotherJob).getName();
                     return name1.toLowerCase().compareTo(name2.toLowerCase());
           PreparedStatement getJobListStmt = null;
           String getJobListSQL = null;
           ResultSet getJobListRset = null;
           try {
                getJobListSQL = "select ID, NAME, DESCRIPTION, COMPANY_ID from VIRTUAL_FAIR_JOB where COMPANY_ID = ?";
                getJobListStmt = tjfConn.prepareStatement(getJobListSQL);
                getJobListStmt.setInt(1, companyID);
                getJobListRset = getJobListStmt.executeQuery();
                while (getJobListRset.next()) {
                     Job holdJob = new Job(getJobListRset.getInt(1),
                               getJobListRset.getString(2),
                               getJobListRset.getString(3),
                               getJobListRset.getInt(4));
                     jobsList.put(holdJob, holdJob.id);
                return jobsList;
           } catch (Exception x) {
                logger.error(x, x);
                if (message.length() > 0) {
                     message.append(", unknown virtual fair error(37) ");
                } else {
                     message.append(" unknown virtual fair error(37) ");
                return null;
So please tell how that inner class will effect the serialization process of the instance of this calss?
thanks in advance.
