I'm using Eclipse 2.0 with JDK1.4.0_01 on Windows 2000. I think the difference is I'm using the "Java protocol". I'm trying to find classes in jar files in the lib/ext folder.
The current ClassFinder seems to work fine for org.apache.jmeter classes. It could "see" the classes in the lib/ext/*.jar's because it created the list of classes for the subclass check. However, it couldn't load the classes to do the subclass check. I have a similar problem in JavaSampler.createJavaclient(). I use the Class.forName(classname) to load the selected class for Java protocol. I had to change to use the Class.forName(classname, boolean, classloader) method. (I'll submit this fix as a bugzilla report after I do more testing.) I don't know enough about ClassLoaders to know if this is correct. I just followed the pattern in NewDriver where it creates an URLClassLoader and sets it as the ContextClassLoader for the thread. -----Original Message----- From: Mike Stover Sent: Wednesday, July 17, 2002 5:30 PM To: Kiewel, Brad; JMeter Developers List Subject: Re: Class loader for ClassFinder That's interesting - it might be more correct than what's there currently. I don't have any such problem, so I'm wondering what your setup is? JDK version? OS? -Mike On 17 Jul 2002 at 15:56, Kiewel, Brad wrote: > I had a problem in ClassFinder not being able to find classes for subclass checks. >ClassFinder could find the classes to put them in the list of all classes, but then >couldn't load the classes to do the subclass check. > > I changed any use of Class.forName from: > > c = Class.forName(strClassName); > > to: > > c = >Class.forName(strClassName,false,Thread.currentThread().getContextClassLoader()); > > This should use the classloader set at start up, and it does not initialize any new >classes. > > Is this fix correct?
