The critical point is that to let application containers have an feasible chance for providing the correct classloading a library (such as OJB) should do the following: If thread.contextclassloader exists use it (remember that it can be null) else use class forname as an fallback If this does not work in Jbuilder 5 and Tomcat there is something wrong with those tools :) /max ----- Original Message ----- From: "Strickstrock, Frank" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, November 26, 2002 9:18 PM Subject: getContextClassLoader > Hi, > I found a mail (see below) in the MailingListArchive, but no answer to the > issue. > When we upgraded to 0.9.5 we also had this problem and had to change several > OJB classes. > Now we'd like to jump to 0.9.7. > Looking at the new OJB classes, I see that still the classes are loaded via: > clazz = Class.forName(className, true, > Thread.currentThread().getContextClassLoader()); > This does not work within our develeopment environment (JBuilder5 & Tomcat). > Any idea, what's the problem ? > Is is also feasable to use "Class.forName(className);" ? > thanks > Frank Strickstrock. > > > From: Mark Rowell <[EMAIL PROTECTED]> > > Subject: getContextClassLoader returning null > > Date: Mon, 2 Sep 2002 15:36:53 +0100 > > Content-Type: text/plain; > > charset="iso-8859-1" > > > > > Hi > > > > I have been running with the latest version of OJB and SQL Server and all is > > OK. > > However, I need to use Excel as a front end and I am using the J-Integra > > Java/COM > > bridge to call my Java stuff (which is exposed as COM objects).
