    program execution depends on java/javaw/debug

    Hi,

    I am verifying a large DSP algorithm using JBuilder 7 and Windows 2000
    Professional. The result of my test depends on the way I run the
    program, though. Here is the situation:

    a) I run the application normally by pressing the run button. The
    output window indicates that "javaw" is used. THE ALGORITHM FAILS, but
    not in the same way from invocation to invocation.

    b) I run the application by pressing the debug button. The output
    window indicates that "javaw" is used. THE ALGORITHM WORKS.

    c) I run the application in a DOS prompt using "java". THE ALGORITHM
    WORKS.

    I realize that my description of my problem is very sketchy. I would
    very much appreciate, however, if any of you could point out any known
    issues that might help in my search for an explanation of my problem.

    Best regards

    Keld

      Hi Keld,

      Be sure you are running from the same JVM/JDK.
      jBuilder installs its own flavour by default and can vary slightly to the
      standard SUN issue..
      To check this go to:
      JBuilder- Tools|Configure JDKs.
      You will probably see it only knows about its own JDK. You can add other
      JDKs from this menu, and then select your project to run using this JDK by
      going to:

      Project|Project Properties.
      On the paths tab you will see the top entry tells you what JDK you are
      running..

      HTH
