Patrick TalmaSubject: Java Extensions Problem
Author: Patrick Talma
Date: 18 Jul 2002 12:11 PM
Greetings -

I having issues with using Java Extensions within the XML to XML Mapper. My biggest question is how to pass arguments to Java code. I've only been able to use functions that do not require parameters.

Here's the java code... SS will not 'see' the second method.

Information:
W2kAS, SP2
Xalan-J 2_4_d1
JRE 1.3.1_02, JRE 1.4.0_01

I'm also seeing an unrecoverable error every other time I try to Register a Class. Attached is the log file.

import java.util.Date;
import org.apache.xalan.extensions.XSLProcessorContext;
import org.w3c.dom.Element;

public class SystemUtils
{
public Object SystemDate()
{
Date d = new Date();
String s = d.toString();
return s;
}

public String init(XSLProcessorContext context, Element elem)
{
String name = elem.getAttribute("name");
String value = elem.getAttribute("value");
return name;
}
}

The Java extension syntax accepted by Stylus Studio requires that methods
have a signature where they return Object.

Changing
public String init(XSLProcessorContext context, Element elem)
into
public Object init(XSLProcessorContext context, Element elem)

should fix it.

About the error, that's a problem recently detected and fixed; you can
download BL91c from:
http://www.exln.com/products/stylusstudio/downloads/iftw_update/stylus%20studio.htm

Hope this helps,
Minollo

Thanks for the quick reply.

I upgraded to the new version and changed my code as suggested. Now when I register the class SS does not see any of the methods... All I see is "unRegister".

Thanks!

Hm... I don't see how that can happen; are you sure the class is still
reachable through the classpath set into Tools|Options|JVM?

Try unregistering it and then going through the register step.

Our processor supports org.w3c.* classes only

You should use a signature like that

public Object init(org.w3c.NodeList context, org.w3c.NodeList elem)

I changed the java code to use org.w3c.dom. Now SS 'sees' the first method but not the second one. Do you have any examples passing arguments to Java from SS? Am I missing something else?

Thanks!

import java.util.Date;
import org.w3c.dom.*;

public class SystemUtils
{
public Object SystemDate()
{
Date d = new Date();
String s = d.toString();
return s;
}

public Object ProcessNode(Element elem)
{
String name = elem.getAttribute("name");
String value = elem.getAttribute("value");
return "s";

}
}

You should use NodeList, not Element (which is not recognized).
Take a look at examples\JavaExtensons\NumberUtils.java

For more details, look at the documentation:
