    I would like to evaluate your product.

    I downloaded the trial version for Linux.

    I started the EnterpriseWorkbenchInstaller_020501.bin executable and I get this exception (cannot find javax.swing.JDialog).

    Strange: from Eclipse, I can import javax.swing.JDialog in a java file with no problem.

    Any idea ?

    It looks like it’s launching with a very old JVM. You’ll need at least 1.3.1 to run it.

    Hello Scott,

    I’m using a 1.4.2 J2SE SDK (JAVA_HOME is set correctly) and a 1.3.1 J2EE SDK (J2EE_HOME is set).

    Anymore idea on this one ?


    PS: I’m using lomboz currently and I’m tired of it. I’d like to see if your workbench is better. If yes, I’ll buy it.

    These two warnings still lead me to believe you’re running the installer with a very old JVM. These options were added quite awhile ago and that fact that they seem to be unsupported is troubling.

    When you open a shell and type ‘which java’ or ‘which javaw’ do you get back what you expect? Try the execute both with the -version option. This isn’t a 1.4.2 JDK or the -Xms -Xmx options would be supported.

    What flavor of Linux are you using?

    We hear that alot around here. Be sure that you install MyEclipse on a CLEAN Eclipse 2.1.0 or 2.1.1 installation. Don’t install it with Lomboz still spread about your plugins directory.

    I’d like to see if your workbench is better. If yes, I’ll buy it.

    I have no doubt that you’ll find it vastly superior. We look forward to your order, once we get this little install problem straightened out.

    if you type “java -version” on the command prompt, what output do you get?
