Hi. I finally got the XSL taglib dancing in WebSphere Application Server. Hans Bergsten was right. The getResourceAsStream() is broken in WebSphere. I changed the ApplyTag.java to use a FileInputStream instead of the getResourceAsStream(), and furthermore I put the xalan.jar and xerces.jar packages from the xsl taglib dist. in the admin server classpath as the two first entries. Then it works!! I do have an additional newbie question. If I use "not-perfect" html in my xsl stylesheet eg. a <p> or <br> tag that is not ended. I will get an error: --- Message: Server caught unhandled exception from servlet [JSP 1.1 Processor]: org.apache.xalan.xslt.XSLProcessorException: The element type "br" must be terminated by the matching end-tag " --- Is there some way to avoid having to use XHTML in my xsl stylesheets? Is there some way to prevent the HTML from being parsed so I can use un-ended <br> tags? Thanks a lot, Thomas Tolborg
