Thank you very much Arved, that was one of my two problems. Now i know how to change the classpath, and the another problem is that like in tomcat I put xerces-1.2.3.jar, xalan-2.0.0.jar  at the beginning of tomcat classpath and deleted the jaxp.jar, parser.jar to run fop, now i do not wich is the order of the classpath in orion...
if someone knows the problem...
Thanks.

I have not used oc4j much, but I started using Orion in early 2000, and they are still pretty much the same thing. If you open orion.jar with Winzip and then open Manifest.mf, you'll see a classpath defined, which is a list of various JARs in the top-level. After that comes JARs in the lib/ directory.
 
If you want a really nice diagram and explanation of Orion [oc4j] classloading, check out http://kb.atlassian.com/content/atlassian/howto/classloaders.jsp.
 
It's been a while since I messed around with this, but according to the diagram and explanation if you specify classes with "-cp" or "-classpath", as in
 
java -cp %path_to_xerces%\xerces.jar -jar orion.jar
 
then Xerces should get picked up _before_ Crimson, which latter is specified in orion.jar Manifest.mf.
 
Another thing I did from time to time was just to edit and replace the Manifest.mf to suit what I wanted to do; now, Orion does use some classes that are specific (or did), but the errors will tell you what you have to leave in or not.
 
Hope this helps,
Arved Sandstrom

Hi all, i have a problem with oc4j ( or ocean ) server and IAS 9x.
i can generate a pdf using tomcat, but i don´t know how to establish the classpath of the oc4j server to generate the pdf.
Oc4j has xerces.jar,xalan.jar and parser.jar and i don´t know what to do to put my jars before them in ocean classpath.
 
Thanks.
