    Eclipse JDK for linux

    The version of Eclipse that is included with PyIMSL Studio requires Java JDK or JRE version 1.5.2 or greater. On linux, you must install the 32-bit JDK or JRE, regardless of whether you are on a 32- or 64-bit platform.

    You can check which version of Java you are using by typing
    $ java -version

    If you see a version < 1.5.2, you should download a new one.

    You can obtain the JDK or JRE from If you have root access, you can download and install the rpm version; otherwise, download the non-rpm version. Both are distributed as self-extracting binaries. Make sure to download the 32-bit version.

    Once you have downloaded and installed the new JDK or JRE, you will need to add the directory containing the Java executable to your PATH. For example:

    setenv PATH /some/java/bin:${PATH}
    export PATH=/some/java/bin:${PATH}

    If you have an old version (1.4) of Java, or if you are using the 64-bit version instead of the 32-bit version, Eclipse will not work. You might see an error message like the following:

    Warning: -Xms40m not understood. Ignoring.
    Warning: -Xmx256m not understood. Ignoring.
    Warning: -jar not understood. Ignoring.

    Why doesn't 64-bit work?

    Thanks for the answer.

    When the PyIMSL Studio was originally put together there was not a 64-bit Eclipse install for Linux. Now that PyIMSL Studio 1.5 has been out for a bit there is a 64-bit Eclipse version. For most Linux users running 32-bit applications is still possible, but if you are in the situation where you do not have any 32-bit libraries on your system, you can download 64-bit Eclipse and Pydev on your own; there is nothing inherently coupled with the Eclipse installation we bundle in PyIMSL Studio. In the big picture, we are certainly looking at providing the 64-bit version of Eclipse for the next PyIMSL Studio release.

    On a side note, are you a big Eclipse fan? With so many editors and IDEs these days I am always curious to hear people's opinions on why they use "heavier weight" tools like Eclipse as opposed to something like gedit or SPE. Folks from more of a computer science background seem to favor Eclipse whereas folks from more of an engineering background tend to go with lightweight editors and separate command window. Or so it seems to me...
