Install maple-ide on 64 bit linux
The maple IDE is only offered as 32Bit java binary/bytecode. On a 64Bit linux with a default java installation maple-ide will refuse to start with the following error:
$ ./maple-ide
java.lang.UnsatisfiedLinkError: /mnt/aaa/bin/maple-ide-v0.0.12/lib/librxtxSerial.so: /mnt/aaa/bin/maple-ide-v0.0.12/lib/librxtxSerial.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch) thrown while loading gnu.io.RXTXCommDriver

You will be able to select a folder for your sketches and then the application will crash.
The problem can be solved by installing the 32Bit version of Java (i chose the sun/oracle one):
$ sudo apt-get install ia32-sun-java6-bin
Then modify the startup script maple-ide to point to the appropriate java installation. Adjust JAVA_HOME and the PATH environment variables:
#!/bin/sh
APPDIR="$(dirname -- "${0}")"
cd $APPDIR
# /usr/lib/jvm/ia32-java-6-sun/jre/bin/
export JAVA_HOME=/usr/lib/jvm/ia32-java-6-sun/jre
export PATH=$JAVA_HOME/bin:$PATH
for LIB in \
java/lib/rt.jar \
java/lib/tools.jar \
lib/*.jar \
;
do
CLASSPATH="${CLASSPATH}:${APPDIR}/${LIB}"
done
export CLASSPATH
LD_LIBRARY_PATH=`pwd`/lib:${LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
export PATH="${APPDIR}/java/bin:${PATH}"
