Which version of Xalan are you using? Your example works correctly for me
using Xalan 2.5.1. I think it is still a classpath configuration problem
with Tomcat. Please try to run the example outside of Tomcat. If it works
correctly, then it is a classpath configuration problem on your side. If it
still fails, please try to download a newer Xalan driver.

Thanks! Unfortunaly the problem didn't disappear, even though the error
message changed..
This is strange because the method org.apache.xalan.lib.ExsltMath.abs
exists. Adding Xalan jars to classpath doesn't help.
Here is what happens:

transformer.transform(new DOMSource(xml), new
StreamResult(System.out));
} catch (Exception e) {
e.printStackTrace();
}
}
