whats allowed in an xsp:logic tag?

[Steven Maring <St...@trcinc.com>]

I have a simple 'try' in an XSP logic-sheet and Cocoon throws an exception:

Cocoon 1.7.2
Error found handling the request.
java.lang.Exception: XSP Java Compiler: Compilation failed for _login.java
        29: Type expected.
                  try {
                  ^

Look at the java file created in the repository : if you don't "output" some
tags before java code, you're not in the populateDocument function, you're in
the class declaration. Thus, you can't have statements, just declarations.

Try to "output" your document root tag before your java code, it should work :

>   <xsl:template match="page">
>
>     <xsl:processing-instruction
> name="cocoon-process">type="xsp"</xsl:processing-instruction>
>     <xsp:page xmlns:xsp="http://www.apache.org/1999/XSP/Core">
>
>       <xsp:structure>
> <xsp:include>java.util.HashMap</xsp:include>
> <xsp:include>java.net.URL</xsp:include>
>       </xsp:structure>
>
    <root-tag>
>       <xsp:logic>
>
>   try {
>      HashMap requestParams = DataServletUtils.getParameters( request
> );
>      String username = (String) requestParams.get( "username" );
>      String password = (String) requestParams.get( "password" );
>

...

>
>       </xsp:logic>

    </root-tag>
>
>     </xsp:page>
>
>   </xsl:template>



Is it a bug, Pier ?
