I have an applet within a portlet (IBM portlet API) on WebSphere Portal Server 6.1. The applet has been in production for a few months, with no issues. I'm about to deploy some changes, so I've asked various people to test the updates. Four people have experienced this scenario: when the applet displays, it displays an old version, a version that is no longer on the server, and that they would not have previously downloaded to their PC. We have tried various solutions to correct the issue: (1) for one user, the solution was to uninstall and reinstall the same version of Java (1.5.0_11); (2) for another user, the solution was to rebuild their LDAP profile; (3) for another user, we tried both of these solutions, and neither resolved the issue; (4) the last user, we are keeping as a test case so we haven't tried a solution. I have even tried renaming the applet jar: the last user (case 4 above) still displayed the outdated applet. I checked the list of applets in the Java control panel, and the newly renamed version is listed, it just isn't being used. It's like this old applet is cached on the PC, but I don't know where to look.
I've searched online about adding cache_archive and cache_option, but they have me a little confused. If this could correct my problem, please explain in more depth.
Here's my object tag to load the applet:
This has me extremely baffled. This problem is delaying a production release, so prompt replies are greatly appreciated. Thanks in advance.
