[2.0.5dev 20030212 snapshot] SWT: Cannot set serializer
Using Cocoon-2.0.5dev from the 2003-02-12 snapshot.
I am trying to write a PDF file to disk using the SourceWriting-Transformer.
The trouble is I cannot seem to set the serializer to "fo2pdf".
It insists on using the "xml" serializer, and even then fails with this message:
ERROR (2003-02-13) 10:48.34:800 [access] (/cocoon-2.0.5-12/test/template.save-pdf) PoolThread-4/CocoonServlet: Problem with Cocoon servlet
org.apache.cocoon.ProcessingException: Exception during processing of cocoon://test/template.xml: javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: org.apache.cocoon.ProcessingException: Cannot get 'xml' serializer
The xml I am feeding to the SWT looks about like this:
<?xml version="1.0" encoding="UTF-8"?>
<source:write serializer="fo2pdf" xmlns:source="http://apache.org/cocoon/source/1.0">
<source:serializer>fo2pdf</source:serializer>
<source:source>../data/template.pdf</source:source>
<source:fragment>
<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
...
</fo:root>
</source:fragment>
</source:write>
I call the SWT like this:
<map:transform type="swt">
<map:parameter name="serializer" value="fo2pdf"/>
</map:transform>
I define the SWT like this:
<map:transformer name="swt"
src="org.apache.cocoon.transformation.SourceWritingTransformer"
logger="sitemap.transformer.filewriter">
<map:parameter name="serializer" value="fo2pdf"/>
</map:transformer>
Any help resolving this would be appreciated,
Tim

sure ase RuntimeException extends Exception, so if you do
catch ( Exception e ) {
}
you also get RuntimeExceptions like NullPointerException and things like
that ...

I mean AbstractXMLFormAction.java says :
perform();
and not
perform() throws someExceptions;

Sounds good, I'll try that :)
will this still be cought more upwards by cocoon tho, so it can generate a
cocoon
error page ? (using <map:handle-errors>, that's what I want really )

I want to report an error more sever then a violation, like a db failing or
so,
or a coders messup ^.^
violations are really only for when the user input on a form is bad right ?

you mean the perform( ) method does not declare a checked exception?
first:
you can use the following trick to throw always an exception
try {
} catch ( Throwable t ) {
throw new RuntimeException( t ) ;
}
this works, since RuntimeException and subclasses don't need to occur in
the signature.
if you want to say that the form has an error, you are better up using
the Form.addViolations( ... ) method.
for more info on Violations look into
org.apache.cocoon.components.validation.Violation
hope this helps

Re: XMLForms prepare/perform nothrow

This is by design.
AbstractXMLFormAction does not know how to handle application specific
errors thrown by the prepare/perform callbacks.
If you can't do anything about an exception which occurs within the method,
then throw a runtime exception.

Subject: XMLForms prepare/perform nothrow
Our company is currently building a project around cocoon(yay:) and
xmlforms.
We are using the current development cvs version.
Working on this it occured to me that the prepare and perform methods of
the AbstractXMLFormAction class don't allow the throwing of any exceptions
whatsoever.
My question is if this is by design or by error, and how I should handle any
errors occuring in my implementations of prepare and perform.
(And if this is by error and not design, if anyone feels like fixin it soon
^.^ )
Many thanks in advance for any replies,
