how to get the xml serializer

[BURGHARD Éric <er...@systheo.com>]

Hi !

I'm writing a new source module.

I set-up some new pipelines with this module in the generator and everything
is working correctly, ... well not exactly

When i try to cinclude the xml from these pipelines in another pipeline i
get an exception (unable to find the xml serializer component from the
serializer selector component).

The problem comes from the getInputStream() method. I took the one that came
with XMLDBSource.java so i guess that xmldb: module has the same problem. 

The serializer is to be selected by

manager = (ServiceManager)
this.context.get(ContextHelper.CONTEXT_SITEMAP_SERVICE_MANAGER);
serializerSelector = (ServiceSelector) manager.lookup(Serializer.ROLE +
"Selector");
serializer = (Serializer)serializerSelector.select("xml");

which throw the exception

The only components (related to serialization) i could find in the manager
is the org.apache.cocoon.components.sax.XMLSerializer and the
org.apache.cocoon.components.sax.XMLDeSerializer, but it seems complicated
for my purposes.

Any idea ?

regards

thanks for your answer,

the xml serializer is effectively declared in my main sitemap ;-(. It's not
the default one, but it is declared as xml.

i use the source module in a pipeline, say test
i can view the test url in a browser. When i debug, the xml serializer is
correctly selected, everything seems to be ok.
but when i <ci:include "cocoon:/test"/> into another document, the exception
is thrown ???.

I can instantiate directly an XMLSerializer, configure it, and recycle it at
the end and it work everytime (url and cinclude). But i think it's ugly.
isn't it ?

You might also consider making the name of the serializer a parameter, 
which defaults to the value "xml". Otherwise, it's this "magic" name that 
must be understood as a silent dependency.

You need to make sure there is a serializer with the name "xml" declared 
in your sitemap.xmap file (or a parent sitemap) before you use your source 
module.
