RE: Call Java Objects

Like a general Java method call. As,

<xsl:variable name="param" select="FooElement"/>
<xsl:value-of select= "JavaMath:findSum($param)"/>

you can pass even XML nodes also and receive them in your java class
through XSLT extension API. Browse through the samples and API provided
with Xalan releases.

Hi venkat .. was helpful.( though dint try as yet :D ) can you also tell
me 
. if i have to pass on parameters to the method how do i do that.
for example

public class MathClass{
public int findSum(int n)
{
  return n*(n+1)/2;
}
}

in this case how do i call the method findSum(int n)..where am i
supposed to 
send the parameter??
