Xerces-J is not directly referenced by FOP or any of its dependencies.
A note on JAXP
-----------------------
Since Java 1.4, JAXP (Java API for XML Processing) is part of the
JRE/JDK. Every JVM includes the APIs and an implementation. However,
older JREs often contain implementations with bugs that are triggered
by code in Apache FOP and therefore need to be overridden. Now, since
JAXP is part of the class library, special precautions are necessary
to replace the original implementations. This is not done by simply
adding new JARs to the classpath as these classes would never be
loaded (due to Java's class loader hierarchy).
Replacing the default implementations involves understanding the
"Endorsed Standards Override Mechanism".
More information can be found here:
http://java.sun.com/j2se/1.4.2/docs/guide/standards/index.html
See also:
http://xml.apache.org/xalan-j/faq.html#faq-N100EF
Essentially, you have two different possibilities:
- add the replacement JARs in the jre/lib/endorsed directory of your JRE.
- Use the -Xbootclasspath/p: option when starting the JVM (may not be
available for every JVM).
