I dont see this class in Xalan 2.5.2

org/apache/xml/serialize/BaseMarkupSerializer  

there is an org.apache.xml.serializer package but thats as close as I can come. Where does that class name come from? Is it a newer version of Xalan?

[Mellihoney Michael]

I don't know.
Should I install this package when I run servlet?
I use tomcat.

[William Brogden]

You don't know where the class name comes from? You better contact the person who wrote that code and find out which version of which parser matches it.

There seems to be such a class in xerces-J - a quick google brings up plenty of JavaDocs. Do you have xerces.jar in your container or application lib directories?

[Mellihoney Michael]

no
where can i download this jar file?

[Frank Carver]

Take a look around the xerces web site: http://xml.apache.org/xerces2-j/index.html

[Mellihoney Michael]

I downloaded xerces.jar.
I placed it to the my_jdk/jre/
and it works
Thanks a lot
