[ns] JNI and NS

["Mark Butler" <mark_wibble@hotmail.com>]

I am trying to use the Java Native Interface with NS (this is to test some 
code we have developed in Java in NS). I am encountering a problem however - 
I link in the libjava.so library with the object files of NS and a new class 
from which I invoke the JVM. The extra line in 'LIB =' in Makefile is:

-L/usr/local/jdk1.1.8/lib/i386/green_threads -ljava

It all compiles and links fine, however when I execute NS the following 
error occurs:

-----------------------------------------------------------------------
application-specific initialization failed: Can't find a usable init.tcl in 
the following directories:
    /usr/local/lib/tcl8.0 /ns/ns-allinone-2.1b6/lib/tcl8.0 /ns/lib/tcl8.0 
/ns/ns-allinone-2.1b6/library /ns/library /ns/tcl8.0/library /tcl8.0/library

/usr/local/lib/tcl8.0/init.tcl: couldn't read file 
"/usr/local/lib/tcl8.0/init.tcl": bad file number
couldn't read file "/usr/local/lib/tcl8.0/init.tcl": bad file number
    while executing
"source /usr/local/lib/tcl8.0/init.tcl"
    ("uplevel" body line 1)
    invoked from within
"uplevel #0 [list source $tclfile]"


This probably means that Tcl wasn't installed properly.
-----------------------------------------------------------------------

If I comment out the extra line that I put in the Makefile, NS compiles, 
links and runs with no problems.

Can anyone help ?

Thanks,
Mark
