Debian supports Java. I am planning to develop my software in Java and
install it in embedded OS.
Does Debian supports full J2SE functions? If No, then can I install my own
JVM in debian.
If you want the official JVM, Oracle provides the official package in .deb
format, so you can just go to their site and install it yourself- though since
Debian packages it, you can and *should* just install the
sun-java6-jdk/sun-java6-jre packages from the non-free repository (this way you
get updates automagically when you update your system). IcedTea is a jvm based
on OpenJDK and Classpath, and it is also in the repositories (though only in
squeeze/testing, I believe). Finally, you also have gcj, which compiles to
native code. So, in short, you have plenty of options.
Actually I m requiring functionalities where I can work with PDF, Excel and
some third party USB Devices using my Software developed in Java.
Do you mean java libraries where you can access PDF/XLS files and USB devices?
For the USB devices, if you don't need raw binary access, you can rely on the
OS to mount it and just read from the filesystem like any other file. jUSB
also works on debian, though i'm not sure if there are packages for that- you
might have to compile them yourself. Or, since linux makes it easy to access
the raw devices through the /dev hierarchy, you can just access them raw if
you're feeling ambitious (DISCLAIMER: THE WRONG WAY). So, in short, use the
OS's ability to mount it for you, or use jUSB. It really depends on what you
want to do.
A quick google provided me with PDFbox (pdfbox.apache.org) and Apache POI
(poi.apache.org) for the PDF and Microsoft office files, respectively. I don't
know anything about these libraries though.
