XLST with Java enhancement

Question

Givent the following java code:
class myClass {
static int num=0;
static public int getNum() {
  ++ num;
  return num;
If I call getNum() in XSL as follows
<xsl:value-of select="Java:myCLass.getNum()"/>
<xsl:value-of select="Java:myCLass.getNum()"/>
is the result:
1, 2
or
1, 1?
I want to ouput 1,2, if not, how can I do?
I can not test in sap now ,hence post this thread, thanks.

Answer 1

thanks.
Well, no matter ++num or num ++.
My point is  if num value can being passed through multiple java calls in the transformation.
I mean when each time XSLT call the java method, the XSLT processor init a new process or there is just one process.
If is new process, then we can not view value changes from different java method.
It's fine to hear that it output 1,2 , which is what I want. That means, XSLT just use one process------
And  XSLT only can call static java method?
Or it can call the non static methods like:  ?
<xsl:variable name="obj" select="java:myClass.new()"/>
<xsl:variable name="test" select="java:obj.xxxx()"/>
