   If there are two default models in both directories, one in the former folder will be used.

5. Can I use JUDE on Linux or MacOS?

   JUDE may run on Linux or Mac OS, however we do not officially support Linux or MacOX for JUDE to run on. (See System Requirements).
   Please see the FAQ 11 for how to set up.
   We strongly advise you to use the recommended Java environment to run JUDE on these non-Windows platforms. For sharing information about running JUDE on Linux or Mac OS, please post on JUDE Users Community Site.

6. What I type into strings does not appear in the Diagram Editor.

   Please use a recommended Java environment.
   - Refer to FAQ 4. "I want to use a specific version of the JavaVM."

7. Can I use Japanese with JUDE?

   Yes. In the GUI, Japanese menu items will be shown in Japanese versions of Windows.
   

   1. Open JUDE batch file (jude.bat or jude-pro.bat) with Text Editor.
      (You can find it in JUDE install folder)
   2. Modify "set USER_LANGUAGE="
      
      
   3. Save the batch file and start JUDE.

8. How can I attain better performance on JUDE?

   The performance level of JUDE depends on the RAM capacity of your machine.
   Try following methods.
   

   • Use the latest Java environment.
     (See FAQ 4. "I want to use a specific version of the JavaVM.")
   • Turn off the mouse cursor tracing option.
     (In some environments, having this option on could make the rendering slower.)
   • Tune some garbage collection settings. (When the value of INITIAL_HEAP_SIZE is set to 16m, the garbage collection does not work fully unless your computer uses the memory more than 16MB)
     *Caution*
     Do not set the value of MAXIMUM_HEAP_SIZE too small because if you do, it could cause "OutOfMemoryErrors" and JUDE will not work properly.

9. It takes rather too long to save or JUDE seems to have frozen when I save project file by [save as].

   This may happen when you are running JUDE on Java 6. Please try following solutions.

   • Use Java 5 instead of Java 6 to run JUDE on.
     (See FAQ 4. "I want to use a specific version of the JavaVM."
   • Clean up files in Desktop, My recent documents, My documents,,etc if there are large files, or zip files in those folders.
   • Use other Look&Feel except Windows. ([View] - [Look & Feel] in Main Menu)

Setup Troubleshootings, etc.

   Currently required operating systems to run JUDE on are Windows Vista, Windows XP and Windows 2000. (See the System Requirements.)
   If you would like to run JUDE on Windows 98, you need to edit the jude.bat (jude-pro.bat) file. (You can find it in JUDE install folder.) Open the jude batch file with Text Editor then set the path of JUDE install folder to "JUDE HOME" then start JUDE by double clicking this batch file.

4. I want to use a specific version of the JavaVM.

   See what versions of Java JUDE supports
   Edit the JUDE start-up batch file (jude.bat, etc.) in the JUDE install folder. Remove "rem" from the following 2 lines, and change the value for "JAVA_HOME" to the install folder of your preferred J2SDK.

   rem set JAVA_HOME=C:\j2sdk1.4.2_10
   rem set PATH=%JAVA_HOME%\bin
                  to
   set JAVA_HOME=[the install folder of your preferred J2SDK]
   set PATH=%JAVA_HOME%\bin
   

5. I get a warning says "J2SDK version is old".

   An old JavaVM is used to run JUDE. Please specify appropriate Java install folder in batch file.
   (Please refer to [FAQ 4."I want to use a specific version of the JavaVM."])

   3. Change the default value for environment variables from [Auto] to a suitable value.
   4. Click [OK].

7. My input is not displayed in real-time when I edit diagrams.

   This happens when you are running JUDE with a non-recommended Java environment. Please check that you are using a recommended Java environment.
   - See System Requirements.
   - Refer to FAQ 4. "I want to use a specific version of the JavaVM."

8. My computer freezes when I exit JUDE.

   This happens when you are running JUDE on J2SE 1.4.1_01. Please use a recommended Java environment.
   - Refer to FAQ 4. "I want to use a specific version of the JavaVM."

9. The JUDE window on my computer flickers and my PC restarts.

   Rendering problems can be caused by the display driver or the Java environment.
   If these problems are not solved by installing the latest version of the display driver or of Java, please try the following option:
   

   -Dsun.java2d.noddraw=true

10. I am unable to open JUDE files.

    JUDE project files (.jude) are upward compatible. If project files are edited by new version, they cannot be opened in older version of JUDE. For information about model versions, click here.
    If you cannot open project files using appropriate version of JUDE, please change the stack size in JUDE batch file.
