Start Forms Builder 11g release 2 in Oracle Enterprise Linux Server 5

I’ve installed Oracle Fusion Middleware 11g Release 2
 Now, I try to run the migrated forms, but I get this error:

I need to recompile my forms with Forms Builder. When I start it, I get this error:

1	$ cd $ORACLE_HOME/bin

2	$ ./frmbld

3	./frmbld: error while loading shared libraries: libhpi.so: cannot open shared object file: No such file or directory

Maybe you’ll find this one:

1	$ ./frmbld

2	FRM-91129: fatal error: message file fmc<language>.msb not found

To solve both errors, I’ve configured some environment variables:

1	$ export ORACLE_HOME=/app/oracle/middleware_11gr2/Oracle_FRHome1

2	$ export PATH=/app/oracle/middleware_11gr2/Oracle_FRHome1/bin:$PATH

3	$ export LD_LIBRARY_PATH=/app/oracle/middleware_11gr2/Oracle_FRHome1/lib:/app/oracle/middleware_11gr2/Oracle_FRHome1/jdk/jre/lib/amd64/native_threads

Now when I start again frmbld I get an X Window with this error message:

1	FRM-91129: fatal error: no value specified for required environment variable FORMS_BUILDER_CLASSPATH

I configure this environment variable to the location of the frmbld.jar file:

1	export FORMS_BUILDER_CLASSPATH=/app/oracle/middleware_11gr2/Oracle_FRHome1/jlib/

And here it is, the Forms Builder running in X Windows:
