javaldx is necessary to make Java work on some UNIX platforms.It prints a
string to std out that consists of directories which have to be included into
the LD_LIBRARY_PATH variable.The setting of the variable usually occurs in a
shell script that runs javaldx.
The directories are from the chosen java installation.
Options are:
--help or -h
[jialiang@localhost ure]$ ./bin/javaldx

/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64/client:/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64/native_threads:/usr/lib/jvm/java-1.6.0-openjdk-1.6.0.0.x86_64/jre/lib/amd64

一句话，javaldx就是让OO可以正常使用java必须添加到LD_LIBRARY_PATH中的lib
