[M Minhat]

Hi All,

Recently I installed these three files (below) in my new laptop which
is run under Windows Vista
i. jdk-6u6-windows-i586-p.exe
ii. jre-6u6-windows-i586-p.exe
iii. java3d-1_5_1-windows-i586.exe

When I run my system application, this message appeared,

: <RequestID=”1119” Action=CREATE” > <FB Name=”SIGNAL_MAPPING”
Type=”ParallelPortDev”/></Request>

Hi!

Have a look at the recent Thread titled, "Something is crashing my FB
runtime." The resolution in Item 6 relates to the existence of
multiple versions of Java on a partly "locked down" PC. Your symptoms
are not exactly the same, but there may be enough similarities to be
of use.

Kind regards,
Neil

Hi Minhat,

first of all if you are running everything without remote devices it's
enough to use
> > C:\fbdk>java -jar -Xincgc editor.jar
to start FBDK (V: 20080101) and all class files inside the fbrt.jar
and inside the lib folder are accessable. Thus, you can command out
your third one.

> > C:\fbdk>cd \fbdk
> > C:\fbdk>rem java -jar -Xincgc editor.jar
> > C:\fbdk>java -cp .\editor.jar;.\lib;.\fb.jar;.\fbrt.jar;.\vv.jar
> > JEditor vnet; vhmi;fst1;service;vmath;netmaster

Furtherone, it looks as there are some or one problem by instantiating
the class ParallelPortDev. The compiling worked corect? Try to open
this FB inside FBDK and try to launch it separately. It looks as you
are using at the variable definition of the class something special,
which could not be found.

Hi Neil,
The problem is solved now.
what I did was editing my editor.ini and fbeditor.bat according to the
version installed
then I un-installed my JAva3D and reinstalled back the JAVA3D.

reboot my laptop and run the system application and it back to normal.

Thanks for lending me your kind opinion,
M Minhat.

Hi Neil,
Thank you for your reply.

I have changed my fbeditor.bat according to the JDK-version along with my editor.ini files but the problem is still unsolved.

This message appeared

Thanks for your help,

Hi Christian,

Thanks for lending hand and ideas. My problem solved now and I can run my system application as usual.

I edit my editor.ini and fbeditor.bat according to JDK and JRE similar version.
Copy all classess files (including JAVA files)  from RXTX and parallel port devices to FBDK folder.
Un-install all 3 JDK, JRE and Java3D.

Re-install all 3 top items and reboot the laptop.

Eureka!!! it suceeded,,,but I have stuck with the earlier installation to Vista about 3 days
before asking help.

Best Regards,
M Minhat.
