FOPSerializer
Hallo,
I am using an integrated version 2.1.x of cocoon in
the xml database exist.
All I want to do, is use an xsl-fo file to transform
my xml to pdf. For this case I added the following
entry in sitemap.xmap:
<map:match pattern=".../x.pdf">
<map:generate src="x.xml" />
<map:transform src="x_fo.xsl" />
<map:serialize type="fo2pdf" />
</map:match>
To use this Serializer I also added an entry, which I
found a thousand times in the web: I added the
serializer in the following way:
<map:serializer name="fo2pdf"
mime-type="application/pdf"
src="org.apache.cocoon.serialization.FOPSerializer" />
But trying to do a request of any kind I get the same
error:
message: null
...
cause: org.apache.cocoon.serialization.FOPSerializer
No details or anything. I just do not know, what
problem cocoon might have with this serializer.
Everbody successfully uses it!
Perhaps I need to configure anything else!
Thanks for your help!
Tina

OK, now the next problem occurs. I have now an
cocoon.jar file in my lib/ directory, where the
FOPSerializer class is included.
There is no more error when I try to make any request
unless I try to use the serializer. I get an
NoClassDefFoundError in almost every .java file and I
lose the connection to my localhost.
How can it be that this error occurs, because cocoon
seems to find the class at that point of the sitemap,
where I define the serializer?
Thanks, and sorry for my allways changing problems :)

Ok, found out, that the exist library includes an
cocoon.jar file which misses the FOPSerialization
class. Now I try to get an complete cocoon.jar file.
Does anybody know if you can get an precompiled jar
file or if I have to compile cocoon myself?

So the problem really is that cocoon can not find that
class. But all the other classes are found. So again
my question is. Where does Cocoon get that package
from, because I neither find a path like this in my
sources nor any of the classes which can be
successfully used. Perhaps this problem lays in my
using the eXist database having an integrated cocoon
version.
Thanks

Can you provide a stacktrace?

Hey, thanks for your quick answer.
Perhaps I did not explain correctly. Even if I have no
pipeline where I use the fo2pdf serializer or any
fo-file, I get that fault anyway. It just occurs
everytime I try to integrate that FOPSerializer Class.
I tried to find out, what this fault means and...
It's the same fault that I get, if I misspell another
serializer such as TexSerializer instead of
TextSerializer. But again and again I checked my
spelling. So consequently I think cocoon just does not
find the class, don't know the reason.
So my question is. Where does cocoon get that class
from. I know scr=
org.apache.cocoon.serialization.FOPSerializer but
thats the same path used by all the other serializer
which successfully work.
I really don't know what this could be. Perhaps that
class has to be integrated in my applikation
seperately.
Thanks

The most likely reason is that your XSL transformation produces
an unacceptable (more or less invalid) FO document.
Debugging hints:
- Replace the PDF serializer in your pipeline with an XML
serializer and save the transformation result to disk.
- Examine the saved FO document, the problem might be obvious.
otherwise:
- Get the FOP distribution.
- Run the saved FO trhoutgh the FOP command line, using the -d
flag.
In general, it has advantages to develop transformations outside
of Cocoon until they are reasonably stable.
