The content of <xsp:logic> as immediate child of <xsp:page> is inserted
into the class scope and can therefore be used to define private methods
and variables.
For variables one has to be aware that the compiled XSP will be recycled,
and initializations will not be repeated. A classic error is that
<xsp:page>
<xsp:structure>
<xsp:include>java.util.Date</xsp:include>
</xsp:structure>
<xsp:logic>
Date now = new Date();
String formatDate(Date date) {
return date.toString();
}
</xsp:logic>
<now>
<xsp:expr>formatDate(now)</xsp:expr>
</now>
<xsp:page>
prints the date when the XSP is compiled, and not when it is called.
HTH, Alfred.

Subject: Re: FOR-loop in xsp:logic section
Hallo,
thank you Chris for help. It's working!
I also I looked at the created *.java class and found out that cocoon is
doing something strange, when the additional elements are missing. Here
is the code:
XSPObjectHelper.xspExpr(contentHandler, obj);
;
}
}
for (int i=0;i< 9; i++)
i=i+1;
Is this a bug in cocoon?
regards
Michael Milvich
