Frequently Asked Questions - Pipeline Troubleshooting

No Java virtual machine was found. What can I do ?

This may come from either an incomplete Java installation, or the JVM location not being listed in your system path.

If you have done it already, please download a Java Runtime Environment (JRE) and install it.

Make sure your system PATH points to the installed Java runtime (on Windows, the PATH is accessible via Control Panel > System > Advanced > Environment Variables)

Alternatively, you can manually specify the location of your Java runtime by adding following lines to the DAISY Pipeline.ini configuration file (located in the installation directory):

  -vm
  c:/path/to/javaw.exe
        
Why do I get OutOfMemoryErrors while running the DAISY Pipeline?

This is a technical limitation: some Java Virtual Machines (JVM) put restrictions on the total amount of memory available on the heap.

You can for instance tell the JVM to let the heap grow to 512 MB by appending the line

-Xmx512m

to the DAISY Pipeline.ini configuration file (located in the installation directory)

Run java -X for the list of options your JVM accepts.

The message view says "Unable to load script <a script name>.taskScript", what can I do ?

These "unable to load" warnings occur because the path to some third-party executable (Lame, Python) has not been set. These paths are configurable in the Paths preference dialog that can be reached from the Window ? Preferences menu item. For detailed explanation please refer to the installation documentation.

Why does the New Job Wizard shows the error message "Unhandled script" when I select some scripts ?

This message is due to some error when loading the corresponding scripts. See the FAQ item: "The message view says "Unable to load script <a script name>.taskScript", what can I do ?".

If the problem is about a custom script you've added to the Pipeline, it can come from any kind of error in this custom script (for instance an incorrect parameter name).

In the documentation view, why can't I access the browser widget with the TAB key ?

TAB is normally used for moving to the next control in the GUI and Shift+TAB to the previous control. However TAB is also used to jump to the next control inside a Web browser. Once in the browser control, it is difficult to leave the browser using TAB because tab will jump to next link in the html page instead of jumping to the next Pipeline GUI control. It was therefore decided to remove the browser control from the TAB list, and to use the F6 key for toggling between the documentation index and the documentation page.

Note that the same behavior can be experienced when browsing CHM Help document with a topic tree view on the left pane and the corresponding html document on the right pane.

Why isn't the Windows installer in English?

This was an error introduced in the 20071221 release, which was fixed on January 4, 2008. Please re-download the Pipeline.

What if I find a bug ? Where should I report it ?

To report a bug, please sign on to SourceForge, and use the DAISY Pipeline Bug tracker. If you are sure this is a bug that pertains to the GUI, please use the DAISY Pipeline GUI Bug tracker. See the "Reporting a Bug" documentation for further detail.

How to export the Pipeline logs ?
