Hello ,
I need some help getting the jini kit working on Linux.
I am trying to get jini working on Linux before switching to other
platforms.
I have the alternative of using Solarisx86 or NT,but I want to do
some research before I do that.
In short I tried it and doesn' t work
here is my configuration :
1- Suse 6.2 ie. glibc2.1
2- jdk1.2-pre-v2 from blackdown
3- reading the bugs' list on blackdown web page I decided to use
THREADS_FLAG=green
These are the Results:
1- with this settings -green flags the example hangs ( no
output
java -cp jini-examples.jar
com.sun.jini.example.service.StartService
2 - with native threads this one works fine except when the GC
thread kicks in I get
SIGSEGV 11* segmentation violation
stackpointer=0xbedff844
Full thread dump Classic VM (Linux_JDK_1.2_pre-release-v2, native
threads):

[... etc]
I suppose this is the bug mentioned on blackdown page.
3- if running still with native threads the jini client (with green
this one also hangs)
I am getting:
java.lang.reflect.InvocationTargetException:
java.net.SocketException: error set
ting options

Any help would be appreciated,
Thanks
Bogdan
