RE: Cocoon 2.0.3 and CastorTransformer

[Michael Homeijer]

Werner,

There aren't many mistakes you can make in things like sitemap or your xml
input for castor. I could send you some sitemap snippets or castor xml input
but they are pretty obvious. Looking at the stacktrace, I don't think you
have made any "obvious" mistakes.

I am using Xerces 1.4.4 and have no problems with it.

HTH,
Michael

Michael,

good news, indeed. I'd appreciate if you could send a working example so
that I
could rule otu my own stupidity ... ;-). Re: Classpath issue, I think
you are
probably right here. In my original email, I asked whether using Xerces
1.4.4

RE: Cocoon 2.0.3 and CastorTransformer

[Michael Homeijer]

Hi,

I have successfully used the CastorTransformer. I am working on a new
version that can be used to marshal and unmarshal, and doesn't use
deprecated classes/code anymore. It's not finished, but I allready use it in
a project.

I have it working in the latest CVS version of Cocoon, but it will probably
also work with 2.03. If you'r interessted, I can mail a copy of the latest
source.

You'r problem sounds like a classpath/version issue, otherwise I can also
find no explanation for the NoSuchMethodError

HTH,

Michael

No, I don't; and I have not read your original email: I've not worked

Thanks, Vadim, for pointing this out. I just changed this back to be in line
with the CASTOR_URI declaration in CastorTransformer.java, i.e. use a
namespace declaration of

xmlns:castor="http://castor.exolab.org/cocoontransfomer";

in my page. Though now I am facing the same problem as in my original email,
iow I am still getting a NPE. Any idea why ?

Actually, this is not error in demo; it's a typo in a transformer 
itself. Thanks for pointing this out.

This namespace typo can easily be fixed because this transformer is 
still in the scratchpad (== alpha).

Re: Cocoon 2.0.3 and CastorTransformer

[Werner Guttmann]

Alan, thanks, that helped to solve one problem, in other words: I am not
getting the NullPointer exception anymore. Strangely enough, it looks like
the CastorTransformer is not kicking in at all now. Please find below
various fragments of code

from the sitemap:

   
 props/castor-bind.xml
   

and

  

  
  
  

  

And here's my viewAccountNatures.xml:



http://castor.exolab.org/cocoontransformer";>
  
  


With all these configs, I'd expect to see the following output ...



  
1
TRADING
  


but I still get

  
  http://castor.exolab.org/cocoontransformer";>

  

Any other idea ? I am at the end of my knowledge. Looking at various log
files, I can see that a CastorTransformer instrance is being created, added
to the pool, used, returned from the poo, etc. Not asingle exception ,
either

Thanks
Werner

PS Btw, the Castor sample shipped with Cocoon 2.0.3 has an error in the

Check the spelling of the XML namespace.

> cocoontransfomer

You probably meant 

  cocoontransformer
  ^

That said, I'd never heard of the CastorTransformer. Based on your mail 
message I had a look in the scratchpad source and mail archives to find 
out more about it. 

In the mail archives, I found a message that mentioned the exact same 
problem. 

HTH,

Alan.

Cocoon 2.0.3 and CastorTransformer

[Werner Guttmann]

Hi,

I am trying to use Cocoon 2.0.3 (Solaris 8, Java 1.3.1_03) with Castor
XML to have an object model inserted into a Cocoon pipeline for further
processing/transformation.

When trying to use CastorTransformer in the following scenario



http://castor.exolab.org/cocoontransfomer";>
  


I get the following exception:

java.lang.NoSuchMethodError

It seems like I've got things configured correctly as I can see in the
stack trace that the CastorTransformer kicks in. I just cannot get my
head around the NullPointerException per se. Any idea what mightbe going
wrong ?

Could this be a problem related to

a) the version of Castor I am using (i.e. 0.9.3.9)
b) the version of Xerces I am using (1.4.4)

Thanks
Werner
