Troubleshooting
As a first advice, I'll assume your path points to the binary directory
from the installation tree of the Java Development Kit.
P: I typed 'java install' in the same directory I put
the file install.class but it reported 'Exception in thread
"main" java.lang.NoClassDefFoundError: install'.
A: Just a non default option. Try 'java -classpath .
install'.
P: The installation wizard seems to work fine, but when I press
'Close' button on the Install Wizard the window closes normally but it
freezes and does not quit to the console where it was started.
A: take a look at here.
P: When I try to start any program under Solaris 2.6 it crashes
and reports 'Segmentation Fault'.
S:
This is possibly due to a missing Solaris 2.6 patch-fix
needed by the production release of the JDK1.2.X. Download the required
patch and apply it to the operating system.
P: When I try to start the graphical user interface it raises
'Exception in thread "main" java.lang.NoClassDefFoundError: javax/swing/JFrame'
or something like that.
S: Type 'java -version' to see whether you're using the final
version of JDK (1.2.X). Remember that there are several naming conventions
for JFC packages that have changed since the beta release. You do need
the final release to run this system. Look at the requirements
list.
P: I was working on the graphical user interface and suddenly
it closed, dumping the stack trace. What should I do?
S: Check the stack trace for the exception message and the
console server logs and send us a report bug describing the context in
which the error occurred.
P: The simulation window seems frozen at the beginning of the
simulation.
S: Check your TCP/IP configurations for DNS. If your computer
has some DNS server specified this machine should be reachable from your
system, otherwise the resolver library will time-out every time. As a last
resort you can disable any DNS searching. This problem is not a bug, it's
just a consequence derived from the way DNS works. The release 1.1_3 tries
to avoid name lookups.
