Error editing build.xml files with Ant Editor in Eclipse

[bkbonner]

Here's the message from the log file. Any ideas.

Config Details comes up blank (weird). I also have XMLBuddy installed. I'll try uninstalling it.

Hi,

Please let us know more details. For instance the Eclipse version and the operating system.

Best Regards,
George

[bkbonner]

I'm running on Win2K SP 4. Eclipse 2.1.0 Build 200303272130.

I'm using Sun JDK 1.4.2.

I have a variety of plugins installed,

• Sysdeo Tomcat
  JBoss XDoclet
  XML Buddy
  JFaceDBC
  Vaultec Velocity
  CodeRally
  Iron and Steel Profiler
  Omondo UML
  Hibernator

Thanks.[/list]

Hi,

From your initial message it seems a Xerces conflict. One thing you can try is to put the Xerces 2.6.0 jars (the latest Xerces version that cames with oXygen) in the endorsed directory, see http://www.oxygenxml.com/download.html#eclipse for more details about this.

Best Regards,
George

[bkbonner]

I'll give it a shot and let you know.

I have a similar problem with oXygen 3.1 and Eclipse 2.1.1, running on SuSE 8.2, j2sdk 1.4.2_03. I'm also using the XML Buddy plugin. In addition to the problems with Ant, I get a problem when I open a closed project. Here's the stack trace:

If I delete the oXygen plugin directory and restart Eclipse everything works again. Any ideas?

[sorin_ristache]

Did you try to put the Xerces jars that come with <oXygen/> in the endorsed directory (usually <home-dir-of-JRE-running-Eclipse>\lib\endorsed) ?

[jlweb58]

Haven't tried that yet -- I'm usually leery about putting 3rd party jars in that directory, since I prefer to control my classpaths explicitly. I'll let you know if I find the time to try it later.

[jlweb58]

The answer seems to be that XML Buddy conflicts with oXygen - it also uses
xerces. Copying the xerces jars to $JRE/lib/ext causes Eclipse to be unable
to start at all, until XML Buddy is deleted. The Eclipse log reveals the following stack trace:

Without XML Buddy in the system oXygen seems not to cause the side effects
mentioned. above.
