"Unexpected exception parsing XML document" in M3

[nilsha]

Hi !

I just installed SpringIDE M3 (from dev-updatesite) in Eclipse 3.2.2 (M20070212-1330) running on jdk5.

Unfortunately when I open a spring.xml-file I got this error:

Unexpected exception parsing XML document from file [(path cut-off)...xml]; nested exception is java.lang.AbstractMethodError: org.apache.xerces.dom.NodeImpl.setUserData(Ljava/lang/String;Ljava/lang/Object;Lorg/w3c/dom/UserDataHandlerLjava/lang/Object;

My workspace's .log-file contains this stacktrace:

!ENTRY org.springframework.ide.eclipse.beans.core 4 0 2007-05-07 15:08:30.812
!MESSAGE Internal Error

Anyone has an idea how to solve this?

Thanks a lot!

This seems to be related to an outdated version of Xerces available somewhere on the classpath in your Eclipse environment (JRE, Eclipse, WebTools). Spring IDE is only tested with Sun's Java 5, Eclipse 3.2.x and WebTools 1.5.x. Are you using a different environment?

Or do you use the JVM's endorsed mechanism (e.g. via the system property "-Djava.endorsed.dirs=<path-to-your-xerces-jars-folder>") to bring your own version of Xerces? You should check your Eclipse start parameters e.g. for stuff like "eclipse.exe -vmargs -Djava.endorsed.dirs=<path-to-your-xerces-jars-folder>".

Please attach the complete output of "Help > About > Configuration Details".

Hi!

Thanks for your reply. I attached you the output of my configuration and the output of Eclipse' OSGi console showing the resolved dependencies of the 'org.springframework.ide.eclipse.beans.core' bundle. It seems the bundle is using version 2.8.0 of Xerces - is this correct?

Regards,
Nils

Hi,

in M3 was a bug in the way Spring IDE resolves Xerces. Refer to this ticket
for more details.

Please try one of the latest nightly builds or wait for the soon to be released M4.

Thanks
