I started a project recently and wanted to use the UML tools in MyEclipseIDE. As long as I am just using the GUI, it all seems to work fine. As soon as I try to modify the properties, eclipse hangs for a minute, then crashes.

The stacktraces in .log are all

java.lang.ClassNotFoundException: org/apache/crimson/parser/XMLReaderImpl
    at org.xml.sax.helpers.XMLReaderFactory.loadClass(Unknown Source)
    at org.xml.sax.helpers.XMLReaderFactory.createXMLReader(Unknown Source)
    at com.genuitec.eclipse.templates.internal.TemplateRegistry.addLibrary(TemplateRegistry.java:55)

Everywhere I have found, it is using Xerces — where is crimson coming from?

I couldn’t reproduce this bug at my end. I tried modifying the properties of a class diagram from the properties tab. This seems like an installation/configuration issue to me.

Can you try cleaning your workspace using the -cleam command ?

If that doesn’t help then you should download the Full Stack installer from the download page and install MyEclippse to a BRAND NEW directory.

Let me know if that helped.

I went ahead and installed jdk 1.5 and tried it again — no problems.

I went through to look for JDK requirements for MyEclipse, but couldn’t find any. What JDK’s is MyEclipse supported on?

You can use JDK 1.4 or JDK 1.5. JDK 6 is not certified to run the Eclpise 3.2 platform at this time.
