        Key: JELLY-45
    Summary: resource lookup in compiled scripts does not work properly
       Type: Bug

     Status: Unassigned
   Priority: Major

 Time Spent: Unknown
  Remaining: Unknown

    Project: jelly
 Components: 
             core / taglib.core
   Versions:
             1.0

   Assignee: 
   Reporter: Vincenz Braun

Description:
Take the following code snippet:

JellyContext context = new JellyContext();
URL url = ImportTestcase.class.getResource("/resources/import.jelly");
XMLOutput out = XMLOutput.createXMLOutput(System.out);
// this works because of the created child context that has knowledge
// of the URL
context.runScript(url, out);

// This does not work because context has no currentURL set
// This results in a NullPointerException when resolving the
// stylesheet
Script script = context.compileScript(url);
script.run(context, out);
out.flush()

A compiled script should manage the lookup of referenced
resources by its own regardless of the context set. If you
cache scripts and use different contexts you do not always know
where the script is from.
That's why context.setCurrentURL(...) is no solution.

// import.jelly
<?xml version="1.0" encoding="ISO-8859-1"?>
<j:jelly xmlns:j="jelly:core" xmlns:x="jelly:xml" >
	<x:transform xslt="import.xsl">
		<x:param name="language" value="DE"/>
		<root/>
	</x:transform>
</j:jelly>
