:
: Running JBuilder
: JBuilder hangs on startup or locks up at the splash screen
: There are several possible causes for this problem. The most common are related to issues with your graphics driver.
:
: To troubleshoot installation graphics driver issues, try the following:
:
: First, visit the website of the manufacturer of the graphics card to download and install the latest driver.
: Windows 2000/XP: If the issue is not resolved, try turning down the graphics card acceleration. To do this:
: Right-click on the desktop.
: Choose Properties|Settings|Advanced|Troubleshoot.
: Set the Hardware acceleration to None.
: Start the JBuilder installation program again.
: Try reducing the resolution and/or color depth. Many high-end graphics adapters have high-resolution modes that can cause some aspects of Java to experience difficulties.
: With certain video adapters you may experience some screen painting problems or crashes when running JBuilder. If this happens, try to uncomment a couple of lines in your /JBuilder2005/bin/jdk.config file:
: vmparam -Dsun.java2d.ddoffscreen=false
: #vmparam -Dsun.java2d.noddraw
: #vmparam -Dsun.java2d.d3d=false
: To uncomment the setting, remove the # symbol preceding the lines and try to run JBuilder again to see if the behavior improves.
:
: If this fails to correct the problem, try one of the other troubleshooting suggestions described in the following sections.
:
: JBuilder throws java.lang.NoClassDefFoundException or java.lang.Object for java.lang.NoSuchMethodError
: This behavior might occur if a third-party JAR was placed in your JBuilder2005\lib or JBuilder2005\jdk\lib directory. Third-party JAR files should be placed in your JBuilder2005\lib\ext directory. There is only one sure way to resolve a corrupted JDK installation: Uninstall and then reinstall your JBuilder product. Make sure that you manually delete any residual files left over before you re-install JBuilder.
:
: Exceptions are reported related to a third-party OpenTool
: JBuilder has a plug-in mechanism, and the plug-ins that you can add to JBuilder are called OpenTools. There are a number of third-party OpenTools that typically come in the form of a JAR file and usually get installed to your JBuilder2005\lib\ext directory. Some OpenTools have been written for older versions of JBuilder and can cause your current version of JBuilder to fail to start. If you are having trouble getting JBuilder to launch, remove any OpenTools and re-start JBuilder.
:
: JBuilder does not start or behaves strangely
: There are some rare times that some unexplainable behaviors occur in JBuilder or it inexplicably will not start when it was working fine previously. One possible fix is to clear out your existing user settings so that new default ones will be used. To do this, delete the .jbuilder2005 and .primetime2005 directories in your "user home" directory. New default ones will be created the next time you launch JBuilder.
:
: Warning: You should make a backup copy of these directories in case you want to borrow some of your previous settings, as you will lose all of them by performing this fix.
:
: JBuilder runs slowly or is not painting correctly
: Most painting problems are the results of issues with your graphics driver. See the section "JBuilder hangs on startup or locks up at the splash screen" for information on troubleshooting graphics-related issues.
:
: If you are receiving out of memory error messages or exceptions, you need to increase the amount of available memory. You can do this by modifying the value of the vmmemmax setting in the jbuilder.config file (located in your JBuilder2005\bin directory). (See the "JBuilder Configuration README" for additional information on setting JBuilder options.) Although JBuilder has minimum and preferred memory specifications listed you need to take into account that your operating system, other applications, and the application that you are developing take memory as well. The simple solution is to add more physical RAM to your machine.
