Hi
I saw there is a JavaVM (SableVM) available for OpenWRT
I wonder if someone has ported RxTx package for OpenWrt
(http://users.frii.com/jarvi/rxtx/)
(RxTx is a Java to serial / parallel port api compatible with Sun CommAPI)

I'm not an expert programmer and I was not able to compile RxTx package following
the instruction on ipkg creation for OpenWrt (available in the documentation)

Any help?

Ciao

Here it is my advancement

        help

- rxtx.control -------------------------------------------------------
Package: rxtx
Priority: optional
Section: misc
Description: RxTx Java Utility
 
- Unfortunately my 'inexperience' with programming and makefile related issue had forced me to
  download and repackage rxtx original zip pack to tar.gz format and put the tar.gz in the 'dl' directory
  to complete the compilation process

-------------------------------------------

Final result:

.......
make[2]: Entering directory `/home/marco/OpenWrt-SDK-Linux-i686-1/build_mipsel/rxtx-2.1-7r2/src'
make[2]: *** No targets specified and no makefile found.  Stop.

make[1]: Leaving directory `/home/marco/OpenWrt-SDK-Linux-i686-1/package/rxtx'

No more advance since now

Any help?

OK,
Finally I was able to create an (almost) complete directory with Makefile and patches to compile RXTX using Openwrt SDK

Unfortunately I was not able to make it run succesfully using Whiterussian v0.9 and sablevm already present in the repository (segmentation fault error in sablevm)

I think I need also to do some settings to point to correct classpath before compile RxTx in the Makefile .... but I'm not sure

I used SUN JDK 1.5 to compile it

You can find my work here
http://www.java-system.com/openwrt/rxtx-2.1-7r2.tar.gz
and I hope someone can check it and maybe give it a try with JamVM

Ciao
Marco

Someone managed to port the RXTX OpenWRT (MIPS)?
