Request for input - Batch processing using JAVA

Hi,

 

I need some input.  I have sent this message to another email address
but got what I think is a bounce back.  If this is a redundant
message... sorry!  Here goes...

 

Our shop runs a good many batch processes for daily reports, data
extracts and data updates.  We are moving more toward java as our
primary language.  Currently we use .jar files for these processes.  The
programs are developed using Eclipse, exported to .jar files, and
uploaded to our Linux server where they are executed.  The .jar will run
under a Unix shell which is started by Cron.  A typical program will run
under a minute to all day plus.  We use common .jar files for shared
code.  Performance is good.  We have no problem distributing the
programs.  

 

The thing we don't like about this strategy is that the code is packaged
in .jar files which are hard to search and, when necessary, cumbersome
to look through. 

 

We talked about organizing these processes into web services.  We could
use Subversion to maintain the library.  This would give us a better
tool for searching our code and organizing reusable functions. If we did
that how would we kill an individual job?  I have also read articles
that indicate that web servers will kill long running processes.  Are
people using web services for batch processing.  Is that the right tool?

 

As an alternative we talked about using large .jar files.  The code for
batch processes could be stored in a common .jar file.  We could create
individual .jar files with a simple MAIN to start a batch process.  The
jobs would be easy to manage using Cron, easy to kill, and we would be
able to use Subversion for library control. How large could a .jar file
like this get?  Is this the right tool for this kind of processing?

 

If you have any comments or something that I should look at please let
me know. I attended a meeting several months ago where Service Oriented
Architecture was the topic.  Does anyone remember the presenter's name.
I would like to address this question to someone who has experience
using SOA.

 

Thanks for your help,

Terry
