Finding Classes and Finding Java

The XPath processor looks for extension classes by using the CLASSPATH environment variable. Ensure that your CLASSPATH references any directories or .jar files that contain extension classes.

The XPath processor tries to load the Sun Java Runtime Environment (JRE) 1.4.x or later. If the XPath processor cannot find a suitable JRE, invoking Java extension functions causes an error during stylesheet processing.

In Stylus Studio, classes are reloaded each time you refresh the preview output, so changes in a class are reflected in subsequent preview output.
