PDA + AXIS + Tomcat

[Suleman Butt <su...@gmail.com>]

Hi,
     Well i'm looking for a solution for the *execution* of OWL-S
described web services using OWL-S API by mindswap on a resource
constraint device (PDA, HP Pocket PC 5500, 400mhz Processor, 128mb
Ram).

Now could anybody suggest me about any SOAP engine for web service
messaging purposes, *AXIS* is one solution for that and it has its
compatibility with *Tomcat* too, but AXIS has a problem of requiring
enough resources which is little difficult task for a PDA to provide.
Now Is it possible to make AXIS requirement specific that is to remove
all those libraries which are not execution dependent or just to add
those components of AXIS onto a PDA which would suffice the task. If
the answer is Yes then wht are those libraries (to be removed) or if
the answer is No then what other Soap engine would be helpful keeping
the above framwork in mind.

Secondly i will also be needing an application server like *Tomcat*
which could be installed on a PDA for hosting web services. I have
been suggested by couple of people that it is practically infeasible
to run Tomcat on such a resourse constraint device as PDA, so what
other solution could be possible. I mean the application server taking
care the above constraints in mind and compatible with soap engine.

Hope to get some good replies.
Thanks in advance,

Regards.

I run Axis under Jetty [1] on my machine.  I don't know whether Jetty is 
  small enough for your environment, but it does claim to be useful for 
embedded applications.  My experience is that it works very well (and is 
a lot easier to manage than Tomcat, which I find unnecessarily complex).

Hello all,
    Does anyone know if there are any free services on the
Internet that allows you to download stock quotes etc via http?
I was wondering if there was already a public webservice that I can use
To retrieve stock data..

Thanks and regards

Hello there,
	I once implemented a 'test' application for a J2ME client
(though it was for my own purposes, never tested in real life..)...i
guess I had similar constraints that you have

I was using  kSOAP package on the J2ME simulator , and on the backend
I was using Axis/JAXM..... I got it working so there shouldn't be any
Compatibility problems between axis and kSoap (though I wrote my app
almost
1 year ago)

Now, tomcat was on the app server at a remote IP...and only thing that I
was running on my J2ME clienet was a kvm..

why would you want to put an app server on your PDA? Can't you have a
remote
app server and your PDA app is just a client?

The app that I have developed was for retrieving / inserting job
opportunities and logic was done in app server.. only logic htat the
client
Had was to ask app server to retrieve jobs, browse thru htem, modify
them
And update htem..

Hope this helps

Regards,	
	marco
