custom java method within XSP
Hello group,
I would like to use a Java method within my xsp. It is not working!
Code:
<xsp:page language="java" xmlns:xsp="http://apache.org/xsp" xmlns:esql="http://apache.org/cocoon/SQL/v2" xmlns:xsp-request="http://apache.org/xsp/request/2.0">
<xsp:structure>
<xsp:include>java.util.*</xsp:include>
<xsp:include>java.text.*</xsp:include>
</xsp:structure><!-- -->
<list>
<xsp:logic>
private static String getParameter(String input)
{
if(input == null || input.equals(""))
return "";
else return input;
}
</xsp:logic>
<p>
test
</p>
</list>
</xsp:page>
Error:
org.apache.cocoon.ProcessingException: Language Exception: org.apache.cocoon.components.language.LanguageException: Error compiling update_all_xsp: Line 287, column 1: illegal start of expression Line 0, column 0: 1 error

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

AW: custom java method within XSP
Posted by Marco Rolappe <m_...@web.de>.
hi thorsten,
the <xsp:logic> element defining the method must be a direct child of the
<xsp:page> element, just like the <xsp:structure> element. in your case the
<xsp:logic> is transformed to code within the generator's generate() method
assuming it will contribute to generation. this of course doesn't work in
this case; your code fragment is supposed to be part of the class
definition, not the generate() method.
