[HELP]Language Exception

[Nicolas Spilman <sp...@umn.edu>]

COCOON VERSION: 2.1m3 servlet
OS: Redhat Linux 7.3

I am trying to pass parameters to an XSP page using the sitemap.  The
sitemap snippet is:

    <map:match type="regexp" pattern="directory/([A-Z]).html">
      <map:generate type="serverpages" src="xsp/directory.xsp">
        <parameter name="letter" value="{1}"/>
      </map:generate>
      <map:transform type="xslt" src="style/main.xsl"/>
      <map:serialize type="xhtml"/>
    </map:match>


The trace is as follows:

Description:org.apache.cocoon.ProcessingException: Language Exception:
org.apache.cocoon.components.language.LanguageException: Error compiling
directory_xsp:
ERROR 1 (org/apache/cocoon/www/intranet/xsp/directory_xsp.java):
...
        // resolver   - org.apache.cocoon.environment.SourceResolver

        /* User Class Declarations */


// start error (lines 67-67) "Default constructor cannot handle exception
type ParameterException thrown by implicit super constructor. Must define an
explicit constructor"
  String letter = parameters.getParameter("letter");

// end error


        /**
         * Generate XML data.

...
Line 67, column 0: Default constructor cannot handle exception type
ParameterException thrown by implicit super constructor. Must define an
explicit constructor


I am basically trying to setup the site so that /directory/A.html will show
all people who's lastname starts with a 'A' instead of having to do
something like /directory/l.xsp?letter=A.  Any thoughts would be good.
Thanks.

It's because the declaration is in the class body and therefore
executed in the default constructor (which does not handle this
exception).

I think this is just because parameters.getParameter(String) throws an 
exception which you are not catching.  An alternative is to use the 
version with a default parameters.getParameter(String, String) which 
does not throw the exception.

Why it gave the specific exception you see I don't quite know.
