Hi! Eric, I am working in a Telecom company U know which manufactures telecom equipments like Telephones, Switches like PABX based on ISDN, TCP/IP, H.323 etc protocols. My question is can J2ME be useful in these devices? if yes then how? And one more thing, there is a JTAPI the Java Telephone App programming Interface, can this can be included in J2ME or can it be run using J2ME. If U answer then I will be very grateful to U, Thanks in advance, Anil

Depends what you want. The J2ME Mobile Information Device Profile is specifically aimed at cellphones. But for things like switches and so on you'd probably want a J2ME profile built on top of the Connected Device Configuration (CDC) or even a plain J2SE implementation. J2ME is really aimed for situations where there are serious limits on memory size and/or processor speed. And it's not clear to me that Java will give you the kind of speed you need in something like a telecom switch. ------------------ Eric Giguere author of: Java 2 Micro Edition : A Professional Developer's Guide PalmTM Database Programming: The Complete Developer's Guide
Anil , I think J2me is for devices like smartcards , pda's , not for advanced devices like telecome switches , telephones. Regarding JTAPI , i think it is more related to J2EE supporting API , rather than related to j2me. I think this will be helpful. SHAILESH.
Whoops, forgot to answer your question about JTAPI... JTAPI is J2SE/J2EE based, so it won't work with J2ME. Perhaps some work is being done somewhere to make a set of APIs suitable for J2ME, but I'm not familiar with them. Eric
