Can I define an instance-variable at an xsp-page?

[Ka...@mn.man.de]

In Jave there are instance-variable and local-variables. If I make an new
instance from a class, then is initialized the instance-variable. But how
is that at xsp-pages. Can I also define an instance-variable like:

<xsp:logic>
     String test1 = new String("hello");    //instance-variable

     public String testMethod1( )
     {

          test1 = "goodbye";
          return test1;
     }

     public String testMethod2()
     {
          String test2 = new String("something");  //locale-variable
          return test2;
     }
</xsp:logic>

Wath make the instance-variable, if diffrent clients use the "testMethod1"?
