Pass object to xslt stylesheet and invoke its methods

Question

I'd like to pass an external created object to a xslt stylesheet to dynamically modify the xslt file at run time. After searching around for weeks, I'm really desperate.
I used Xalan transformer's method setParameter(name, obj) to initialize a variable in xslt file with this object. Then the object's method was invoked.
The class that I want to invoke the method:
class test{
private String testString = "abc";
public String valueOf(){
return testString;
xslt file:
<xsl:param name="myType"></xsl:param>
<<xsl:variable name="new-pop"
select="my-class:valueOf($myType)">
Any help is greatly appreciated.
Thank you.

Thank sabre. I have looked through your link.
The problem is for all the info I knew, we can only
create a new object inside the stylesheet using new()
and then invoke this particular object's instance
method.
However, I want to pass an already created java
object into the stylesheet and then invoke its
method.
Xalan seems to not allow this. I have tried to pass
an object as the parameter of
transformer.setParameter(name, object) but it doesn't
work.
Any one know what 3rd party transformer that allow to
pass object directly into xslt?setParameter will work... in your XSL, you should have
<xsl:param name="myParam" />set the parameter in your transformer like what you had in your post...
In your XSL header, you must declare the your Java object namespace and path, such as:
xml:myJavaObject= "com.MyCompany.MyJavaObject"then in your template or anywhere that you want to use your object, you should have:
<xsl:variable name="runningMyMethod" select="myJavaObject:myJavaMethod($myParam)" />The XSL will treat $myParam as the instance object, if there is any other method parameters needed to be passed in do:
<xsl:variable name="runningMyMethod" select="myJavaObject:myJavaMethod($myParam, 'blah', 'blah')" />Good luck.
