Hi,
Well i have a HP PPC h5500 (P2 400mhz, 128 mb RAM, WIN CE) and i want to execute Semantic Web Services on it. The softwares i will be using require Java 1.3 or above. The api or S/W i'll be requiring are :

1) Java OWL-S api
2) RDF Parsers (jena api)
3). XSLT parser api
4). WSDL parser (AXIS soap engine)

In all i'll be using XML parsing regressively. I have read from few sources that there are currently 3 JVM's available for PPC and all of them have JDk 1.1.8 support :

1). IBM J9 JVM
2). NSICOM's CrEme JVM
3). Insignia's Jeode JVM (comes in bundle with the above specified PPC)

Now is that true that SUN has no J2ME specification (JVM) for PPCs ?

I have seen few JSRs at sun.com like JSR 172: J2METM Web Services Specification and JSR 75: PDA Optional Packages for the J2METM Platform, so how could these be put into use ?

What about performance issues if anybody has experienced this practically ?

What could be the best solution for me i mean JVM to select from above or anyother if available that should support JDK 1.3 of above ?

Why there are those 2 JSRs avaialble if sun doesnot provide JVM for PDAs ?

I will also be requiring an application server on my PPC and somebody has suggested me to check Jetty for that + soap engine AXIS, so all this seems little resource requiring but i'm not sure whether this works or not.

In all i'm in desperate need to check for all these situations but i'm quite confused
in how to get myself started. i'm very much new to this J2ME environemnt so need some help.....

Pls do also suggest me some meaningful pointers where i can assess how much resources does my PPC support.

Few more info about my PPC if i'm not wrong : MIDP 2.0/CLDC 1.1, CDC/Foundation/Personal Profile 1.0, JSR-075 FileConnection and PIM optional packages on either profile.

Looking forward to some good replies.
Regards.
