PATH and LD_LIBRARY_PATH on Linux

Question

Hi
I want to run an executable within a java program, since the executable requires certains dirs in its PATH, i need to set the PATH and LD_LIBRARYPATH. I am not sure how to set the LD_LIBRARY_PATH since i dont know what the system property name for the same is in java
StringBuilder commandToExecute = new StringBuilder();
               commandToExecute.append(userdir.getAbsolutePath());
               commandToExecute.append(File.separator);
               commandToExecute.append("apps");
                 commandToExecute.append(File.separator);
               commandToExecute.append("web");
               commandToExecute.append(File.separator);
               commandToExecute.append("bin");
               commandToExecute.append(File.separator);
String path = "//home//rick//server//bin//" + ":" +"//home//rick//web//bin//";
    System.setProperty("java.library.path", path);
    System.out.println("PATH after modification and before running exe on unix : " + System.getProperty("java.library.path"));
// How to set the LD_LIBRARY_PATH? What is the java system property that corresponds to it?
                   commandToExecute.append(exe_UNIX_COMMAND);Could you please let me know what java system property represents LD_LIBRARY_PATH?
Thanks a lot.

If there is no java system property for LD_LIBRARY_PATH, then what is the other way to set it via java code?Probably the simplest thing would be to invoke a shell script that sets it.
Otherwise you might be able to invoke a shell, set the env var as part of the shell's invocation, and tell the shell to execute your other program. I'd go with the script approach though.
If you need to know what that var was in the context of the environment where your JVM was spawned (which seems unlikely), you should be able to get it with System.getenv.
