Re: Freenet on Raspberry pi

I figured this out, in case anyone else needs a solution in the future.
The issue was caused by the precompiled Java Service Wrapper not  
supporting the specific ARM architecture on the Pi.

Here's the steps I took that rectified the issue (and other issues  
along the way):

1. Install Oracle's JDK instead of openjdk/jre (you'll need the jdk  
for later steps)
2. Install ant
2. Download the latest Java Service Wrapper source from  
http://sourceforge.net/projects/wrapper/files/wrapper_src/
3. Set your environment's $JAVA_HOME and $ANT_HOME to the locations of  
jdk and ant. If you mess those up, the wrapper compiler will tell you.
4. Compile the wrapper (run build32.sh)
5. Copy the generated wrapper executable in the bin directory to the  
wrapper dir in Freenet, replacing the current wrapper-linux-armhf-32  
exec in Freenet's bin
6. Copy the .so file from the lib dir into Freenet's lib as  
libwrapper-linux-armhf-32.so
7. Finally, jar up the org dir in the classes dir - jar cf wrapper.jar org.
Copy the new wrapper.jar file into Freenet's dir.

I *think* you can skip the last step if you compile the same version  
of the wrapper as the one used in Freenet. I think currently it's  
3.5.20 while the latest wrapper is 3.5.23.

And finally, enjoy the perpetually high load on your pi while freenet  
is running :).
I'm not sure how practical this is in the long run but it was fun  
trying to get it to work.
