Thank, David. I'll talk to you tomorrow.
Yes, the validate(String fileName, InputStream is) in TestManager is static
method.
Bruce: What should I do in order for my jar visible to the scripting code.
Right now, I just drop it into %BABELDOC_HOME%/lib directory along with all
the jars that BabelDoc depends on.
David, I don't follow what you said about batch file and
externalApplication Stage. I'll try to see if there are some examples and
talk to you later. Thank you.

Hi Qin,

Nope. The best you can do is take document.get("file_name"), which will
return the file name as a String, and use it to instantiate your own File
class.

I haven't used this one, but I'm guessing that it represents the internal
document. If you haven't changed the original document through some type
of
transformation, then it should represent the original file.

Is validate() a static method? If not, you'll need to instantiate the
TestManager class first. Also, I'm not sure if simply placing the class
into
the %babeldoc_home%/lib directory is sufficient. You may need to put it
into
the CLASSPATH, as well. Perhaps Bruce can comment on this?

I'm happy to talk to you, however I'm leaving the office for most of the
day
in a minute. You may want to consider an alternative way to get this going
for now:
1. Create a batch file that you can run from the command line, passing the
name of a file, that will run your validation routine.
2. Use the ExternalApplication stage to run your batch file. Be sure to
set
the pipeInResponse attribute to true.
3. The output of the external program will placed in an attribute called
ExternalApplicationResponse. From there, you can place it into the main
document, test it, slice it, dice it, etc.
Hope this helps. If not, I'll be available later this evening or tomorrow.
