using XML String in XSP

[Gould, Troy (ELS)]

I'm using cocoon 2.0.4 and having difficulties with the
xsp-util:include-expr and xsp:expr tags.

I have a method in a class that returns a XML Document as a String which I
want to utilize within an xsp page.  However, I don't want the string to
come back as text because the '' tag (and others) will be escaped as lt;.
I want the returned xml string to become part of the SAX stream.

Originally, I was using:

xsp:logic
String testDoc = WebServiceClient.getDocument(testDoc.xml);

content
xsp:expr
testDoc
/xsp:expr
/content   

/xsp:logic


Then, I went to using:
xsp:logic
String testDoc = WebServiceClient.getDocument(testDoc.xml);

content
util:include-expr
util:expr
testDoc
/util:expr
/util:include-expr
/content   

/xsp:logic

All this was doing was printing out XML with util:include-expr and util:expr
as tags.  The tag processor seems to not be processing my util namespace
tags.

I'm not sure what I'm doing wrong.  I see from reading documentation that
there was a fix in version 2.0.4 where xsp-util:include-expr/ includes
any object, converting it to string.

The real problem is can I use XSP to get a XML Document as a String and
still have it put into the SAX stream as a Node or do I need to just write
my own custom generator to do this instead?

Thanks in advance!

RE: using XML String in XSP

[Gould, Troy (ELS)]

I've tried your suggestions for whitespace and alternative xml tags (and
attributes) and it still craps out.

The example from Cocoon Developers book (shown below) doesn't even work

xsp:logic
String xmlString = testA test value/test;
util:include-exprutil:exprxmlString/util:expr/util:include-expr
/xsp:logic

Even putting the xsp:expr/ tag around xmlString doesn't work either.  I've
tried addeding/removing whitespace all over the place and still not working.


The generated .java code for the .xsp file is just putting the following in
the code:
String xmlString = 

which is where I see the errors in the log files.

Seems like a definite bug.


I'm to the point where I'd rather just write my own Transformer.   Seems
like a bug like this has to be a show stopper for a lot of people.

So, do you use the correct namespace for them? Does your XSP have a
correct structure (e.g. some top level tag starting the page?)

 The real problem is can I use XSP to get a XML Document as a String and
 still have it put into the SAX stream as a Node or do I need to just write
 my own custom generator to do this instead?

This is possible from XSP.

AbstractGenerator and Poolable

[Gould, Troy (ELS)]

I see that the AbstractGenerator implements Poolable.  I was wondering what
object in the Cocoon framework is responsible for using Excalibur's Pool
implementation or another implementation based on the AbstractPool.

Does anyone know what object is requesting a Generator from some Pool
implementation?

Thanks,
Troy Gould
