I had an old but working JDO configuration with kodo working perfectly from compile, database and limited/requisite functionality. Incredulously it did everything that I needed. However I needed to upgrade to TC5.5.30 and now the exact same web.xml which worked under TC 5.0.x is failing in JDOPlugin iinit(ActionServlet servlet, ModuleConfig config). What default configuration in TC 5.0.x worked that I lost in TC 5.5.30? I the defaults would work and that I understood it. I would really like to understand the deeper issue(s). tia.
