Re: Eclipse, Ant and Leopard Problem

I have had a similar issue since migrating to Leopard.  What I was seeing is that I can't run any JUnit test through eclipse.  I get the same error about SAXParserFactoryImpl.

I am just offering guesses since I haven't had a whole lot of time to dedicate to solving the issue, but it seems to be related to -XstartOnFirstThread.  

The reason I have come to that hypothesis is because I found out that if I ran a JUnit test through eclipse, then pulled the command-line for the test run (using ps in the terminal), -XstartOnFirstThread was on the command-line.  If I just remove that flag and run the same command from the terminal, it runs fine.

The only piece of info I found online (I haven't searched in a while) was this message from the eclipse mailing lists:  http://dev.eclipse.org/newslists/news.eclipse.platform.swt/msg37971.html

That person thinks -XStartOnFirstThread causes problems with classloaders in Leopard.

Hello,

I realize this is truly an Eclipse issue, but I thought I might shoot the problem here as I know there are a lot of Eclipse users here.

I'm having trouble building a project using an external Ant and Eclipse.  Builds  
fine in Tiger, doesn't on Leopard.  When I try to build the project I  
get this error:

BUILD FAILED
XML parser factory has not been configured correctly: Provider  
org.apache.xerces.jaxp.SAXParserFactoryImpl not found

I've set Ant Home to be /Library/Bea/weblolgic92/server (just as I did  
on Tiger).  I have verified that SAXParserFactoryImpl resides in  
weblogic.jar and weblogic.jar is part of the Ant classpath.  I can  
build the project via the command line by navigating to the project  
directory, use the external ant to build by:

/Library/Bea/weblogic92/server/bin/ant build-all

and the project will build perfectly.  Also, this must be a Leopard  
thing because the same configuration builds just fine in Eclipse on  
Tiger (same Eclipse version, same WebLogic version).  Does anyone have  
any suggestions?

Thanks in advance.
Matt

10.5.1
Eclipse 3.4M4
WebLogic 9.2
