Passing parameters to XSP from sitemap
Hi all,
I am trying to pass parameters to XSP from sitemap.
My sitemap:
<map:match pattern="*/data/**">
<map:generate type="serverpages" src="data/{2}.xsp">
<map:parameter name="lang" value="{1}"/>
</map:generate>
<map:serialize type="xml"/>
</map:match>
My xsp:
<?xml version="1.0" encoding="windows-1251"?>
<xsp:page language="java"
xmlns:xsp="http://apache.org/xsp"
xmlns:esql="http://apache.org/cocoon/SQL/v2">
<data>
<xsp:logic>
String lang = parameters.getParameter("lang");
</xsp:logic>
<news>
<esql:connection>
<esql:pool>mypooldb</esql:pool>
<esql:execute-query>
<esql:query name="news_list">
select ld.subject, ld.annotation
from langdocument ld
where ld.document_id=65
and ld.language='<xsp:expr>lang</xsp:expr>'
</esql:query>
<esql:results>
<esql:row-results>
<item>
<subject><esql:get-string column="subject"/></subject>
<annotation><esql:get-string column="annotation"/></annotation>
</item>
</esql:row-results>
</esql:results>
<esql:no-results>No results</esql:no-results>
<esql:error-results>Errors</esql:error-results>
</esql:execute-query>
</esql:connection>
</news>
</data>
</xsp:page>
When I request the page "http://localhost:8888/myproject/en/data/news" I have the following error:
org.apache.cocoon.ProcessingException: Language Exception: org.apache.cocoon.components.language.LanguageException: Error compiling news_xsp:
ERROR 1 (org\apache\cocoon\www\antanta\data\news_xsp.java):
...
this.characters("\n");
// start error (lines 306-306) "Unhandled exception type ParameterException"
String lang = parameters.getParameter("lang");
// end error
String current_id =
(
(XSPRequestHelper.getParameter(objectModel,
...
Line 306, column 0: Unhandled exception type ParameterException
What is wrong?
My environment is the following: tomcat 4.1.18, cocoon 2.1M1, Win XP.

Re: Passing parameters to XSP from sitemap
Posted by Peter Velychko <v_...@ukr.net>.
Hi all!
I've solved my problem. The correct line in XSP should be the following:
String lang = parameters.getParameter("lang", null);
