Out of classpath real-estate

Question

We have a large complex application and we are starting to run out of
room in the weblogicclasspath on windows and unix. We use lots of 3rd
party jars to make our applicaiton work, like
mail.jar,activation.jar,xerces.jar,xalan.jar and many more.
Between all the stuff weblogic requres and our app requires were running
out of room (nt has hit its max and so has our unix shell)
I am thinking about using java extensions to help out here. For things
that are low level like mail,and xml parsers, is it ok to put them in
the ext directory instead of the weblogicclasspath. This would free up
some room for me. Im just worried that this will negatively effect
weblogic.
Also, we have had problems where some of our xml classes are being
loaded from weblogic and some from our xerces.jar we add. Is there a way
to make sure we use ours instead of weblogics (since weblogics are quite
old).
thanks
Joel

Answer 1

I had exactly the same problem a while ago (command line was getting too
long) and I used a launcher class which reads classpath from a config file
and sets it before starting WebLogic:
public class WebLogicLauncher {
public static void main(String[] args) {
try {
String weblogicClasspath = ... read it from file ...
System.setProperty("weblogic.class.path", weblogicClasspath);
Class wlServer = Class.forName("weblogic.Server");
Method wlMain = wlServer.getMethod("main", new Class[] {Class.forName("[Ljava.lang.String;")});
wlMain.invoke(null, new Object[] { args });
} catch(Throwable oops) {
oops.printStackTrace();
