Hi John, All I can think of with the information you've given is to check that your class is on the classpath.
Could you send your stylesheet and Java class, and also show how you invoked the transformation and what the full error message was?

I've got an existing XALAN-J based system (I didn't create it) that I'm trying to add on to. I want to create a simple extension function in JAVA. The XALAN-J documentation says stuff written in JAVA doesn't require BSF. So - I went to work on one of the XSLs: added a simple namespace and defined a component as in the example at http://xml.apache.org/xalan-j/extensions.html#ex-java I wrote and compiled an extension function; currently just of the "Hello, world" sort. So far, so good. Problem arises when I try and use the extension function in something like <xsl:value-of select="mytest:hello()"/> XALAN throws a "can't find the class" exception no matter where I put the .class file. Those folks out there with some experience implementing JAVA extensions - I'd be grateful for some help figuring this out. I'm sure it's something very simple, but I don't know where to look next. ********************************* John F. Wade, PE MSFC iPV Integration Lead
