Session persistence

Question

Hello everyone,
          I'm currently working with WL 6.1 and I'm having trouble with the
          persistence of some session variables which are initially created
          correctly on the server side, and they get lost (null) once the Web
          clients need to access its value.
          This is the error which is being written on a log file:
          <May 13, 2003 3:05:09 PM EDT> <Error> <HTTP Session> <Could not
          deserialize session data
          java.io.NotSerializableException:
          Things were woriking perfectly, but suddenly after bouncing the server
          instance several times, in order to pick up the latest changes in my
          classes, I started to get this error once the server tries to load the
          jsp.
          JSP Code:
          <%
          Integer businessID = (Integer) session.getAttribute("business_id" );
          Util.isCapitolBusiness(businessID.intValue())
          %>
          I appreciate your help.
          Regards.

Answer 1

is the object being put in session context serializable.. Also in
          other to avoid any generated classes issues delete all the classes
          whcih weblogic generates as part of deploying the application. That
          should atleast mitigate one explanation for your problem.
          Hope this helps
