Rational Developer for System z

The Welcome page of a perspective is blank

To resolve this problem, install the required 32-bit Linux package from the Linux install disk or package repository.

Note: For a partial list of 32-bit Linux packages that are prerequisites for running Developer for System z® on a supported 64-bit Linux operating system, see IBM® Rational® Developer for System z Version 8.0.3: Installation Guide.
Operating systems:
  • Red Hat Enterprise Linux V5 or V6 64-bit
  • SUSE Linux Enterprise V10 or V11 64-bit

Problem:
When a perspective is opened for the first time in a new work area, the Welcome page of the perspective is blank and an error message is displayed when the Welcome tab is closed.

Symptoms:
  1. The Welcome page of the perspective is blank, as described above.
  2. When the Welcome tab is closed a Problem Occurred error window opens with the following error message:
    Unhandled event loop exception
    No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]
  3. When this window is closed an Internal Error window opens with the following error message:
    An SWT error has occurred.
    You are recommended to exit the workbench.

Analysis:
The Welcome page requires 32-bit versions of the Linux operating system libraries. Some of these libraries are not installed by default when the Linux 64-bit operating system is installed.

Resolution:
To resolve the problem:
  1. Install the required 32-bit package from the Linux install disk or package repository:
    Table 1. Required 32-bit package
    Operating system: 32-bit package:
    Red Hat Enterprise Linux V5 or V6 64-bit xulrunner.i686
    SUSE Linux Enterprise V10 64-bit mozilla-xulrunner-32bit
    SUSE Linux Enterprise V11 64-bit mozilla-xulrunner190-32bit
    For example:
    • For Red Hat Enterprise Linux V5 or V6 64-bit, enter the following command on the command line of a terminal window:
      yum install xulrunner.i686
    • For SUSE Linux Enterprise V10 64-bit, enter:
      zypper install mozilla-xulrunner-32bit
    • For SUSE Linux Enterprise V11 64-bit, enter:
      zypper install mozilla-xulrunner190-32bit
  2. Close and reopen Rational Developer for System z.

The Welcome pages should now work properly.
