Check that you are passing correct parameters to installFunction:
http://xml.apache.org/xalan-j/apidocs/org/apache/xpath/compiler/FunctionTable.html

It's signature is: installFunction(java.lang.String name, java.lang.Class func)

As you can see it should be a string and then a class, not org.apache.xpath.Expression type. You can try calling the .getClass() method of your org.apache.xpath.Expression variable.

Thanks mwvisa1. But Xalan-2.6.0 has over-ridden installFunction methods as :

1) installFunction(String, Expression). This one matches with the call we are making.

2) installFunction(Expression , int)

What you are talking about is in Xalan-2.7.1. I am working on 2.6.0.

looks like a different version of the XPath library precedes the intended version in CLASSPATH!
how do you run the application?

If there's another version on your classpath that takes precedence the 2.6 will never be used.

And if you're running (for example) from an application server the system classpath will be completely ignored so it doesn't matter one bit what you put on it.
