RE: Xalan extension functions

[Sushy Behal]

 This works . Try this it would work too in your code if everything else is
fine 

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet 
xmlns:xsl= <http://www.w3.org/1999/XSL/Transform>
http://www.w3.org/1999/XSL/Transform 
xmlns= <http://www.w3.org/1999/xhtml> http://www.w3.org/1999/xhtml 
xmlns:xalan= <http://xml.apache.org/xalan> http://xml.apache.org/xalan
xmlns:mytest="MyTest"
extension-element-prefixes="mytest"
version="1.0">

<xalan:component prefix="mytest" functions="nodeLinkRef ">

  

<xalan:script lang="javaclass" src="MyTest"/>


 

</xalan:component>

<!-- Somewhere in code -->

<xsl:value-of select="mytest:nodeLinkRef(.)"/>

 

//Modify JAVA CODE

 

import java.util.*;

//import all other relevant packages

public class MyTest 

{

 

 public Node nodeLinkRef(Node node)
  {
   
   
     try{
        // do anything yu want here and beand this will handle exceptions  

   }
   catch(Exception e)
   {
    e.printStackTrace();
   }
     return node;
  }

}

Thanks
 
Sushy

It's not Monday anymore.  Oh well.
 
Here's the test case java code.  It does exactly nothing.
Import java.util.*;

public class MyTest 

{

public MyTest() 

{}

}

 
The namespace and component definitions are:
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet 
xmlns:xsl=http://www.w3.org/1999/XSL/Transform 
xmlns=http://www.w3.org/1999/xhtml 
xmlns:doc=http://nwalsh.com/xsl/documentation/1.0 
exclude-result-prefixes="doc" 
xmlns:xalan=http://xml.apache.org/xalan
xmlns:mytest="MyTest"
extension-element-prefixes="mytest"
version="1.0">

<xalan:component prefix="mytest" functions="MyTest">
<xalan:script lang="javaclass" src="xalan://MyTest/"/>
</xalan:component>

 
 
Down in one of the templates I've added a line that says:
<xsl:value-of select="mytest:MyTest()"/>

 
And the error I get is:

(Location of error unknown)XSLT Error
(javax.xml.transform.TransformerException):
javax.xml.transform.TransformerException: Instance method call to method
MyTest requires an Object instance as first argument

..which isn't the error I remember getting last time I tried this, but one
thing at a time.
 
Suggestions?

Classpath has been my thought, too.  I'm a real beginner at this, and the
environment I'm working with has two variants, so I'm not sure how to
determine what the classpath is in each case.  
But, we'll start with the stylesheet and JAVA code on Monday and go from
there.
 
Thanks.

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?
