Thank you very much Marco!

Solution:
<xsp:logic> element defining the method must be a direct child of the 
<xsp:page> element

My Case (Problem):
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp">
<list>->This custom element was not allowed here!
<xsp:logic>

Explanation:
The <xsp:page/> element has two different parts. One part where you can 
put your class definition (1) and the other part is within the 
generator's generate() method (2). (1) has to be a direct child of 
<xsp:page/>. (2) starts a soon you use a custom element (<list>). Java 
method has to be declared in (1) and can then be used in (2).

example.xsp:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp">
<xsp:logic>
  private static String getParameter(String input)
   {
     if(input == null || input.equals(""))
       return "The parameter you have been requested is NULL or ''";
     else return input;
   }
</xsp:logic>

   <page>
<p>Parameter: 
<xsp:expr>getParameter(request.getParameter("STREET"))</xsp:expr></p>
   </page>

</xsp:page>

if you want to test it with your cocoon-app, save the example.xsp and 
call it LIKE (you have to modify your sitemap.xmap)
1) http://localhost:8080/YOURAPP/example.xsp?STREET=
2) http://localhost:8080/YOURAPP/example.xsp?STREET=test
