Re: [xep-support] XEP fails with Crimson error

It means that Crimson is the default XML parser in your Java
environment.

The most probably this is not the crimson.jar from XEP distribution.
In order to make sure for that, please remove any occurrences of
crimson.jar from the script you are using for launching XEP.

If the removing of crimson.jar does not help, it means that "another"
Crimson is used in your environment.

Some applications may explicitly set
javax.xml.parsers.SAXParserFactory property. It could
be done by adding an appropriate record to the system properties or by
creating a special '.properties' file in jre/lib/ subdirectory.

Another possible way is crimson.jar in the JVM bootstrap classpath.
But Java 1.5 (unlike Java 1.4) does not have Crimson as a part of the
package.

You are correct.
But it is not Crimson shipped with XEP that cause the problem.

> Any ideas?

You may find out the used crimson.jar and replace it.
But neither "finding out", nor "replacing" is an easy task.

The simplest way to resolve the problem is to tell Java to use a
specific XML Reader.

Add the following property to the XEP execution command:

-Djavax.xml.parsers.SAXParserFactory=com.icl.saxon.aelfred.SAXParserFactoryImpl

It will force usage of Saxon Aelfred XML parser.
