Hello, I'm having some problems accessing xindice from
a remote computer - getting an XMLDbException error
from XindiceBrowser. I've boiled the problem down to
the generated /docs/db_bootstrap.ior file. For some
reason on my linux box, the generated ior lists
127.0.0.1 as the host and on windows 2000 it lists a
real ip address. Consequently, my windows 2000
instance can accept remote connections but my linux
instance cannot.
I downloaded JacOrb and used the
org.jacorb.orb.util.PrintIOR utility to print the
db_bootstrap.ior file. I get the following printout
for
xindice 1.0
redhat 8.0 linux running both jdk's
jdk 1.3 (build 1.3.1_08-b03, mixed mode)
and
jdk 1.4 (build 1.4.1_03-b02, mixed mode):

The funny thing is that when I run the same *exact*
instance (just copied the files from the linux box
onto a Windows 2000 box and ran it) on Windows 2000,
the bootstrap.ior file makes a lot more sense
C:\srv\xindice\docs>java -cp c:\tool\junk\jacorb.jar
org.jacorb.orb.util.PrintIOR -f db_bootstrap.ior

As expected, remote clients have no problem accessing
the Windows 2000 instance as they will be able to
resolve 192.168.57.4 but clients cannot access the
linux instance as they will never resolve 127.0.0.1 to
the xindice server instance.
Does anyone know what xindice uses to figure out what
"host" to generate in the ior file? How do I tell it
what ip address to use as the host?
My 'hostname' is set on my linux box and it is not
127.0.0.1. I tried changing the system.xml to listen
only on a real ip address - which xindice does but the
ior file still reports 127.0.0.1 as the host. I also
ried to
org.jacorb.orb.util.FixIOR 192.168.57.20 40168
db_bootstrap.ior
and also
org.jacorb.orb.util.FixIOR 192.168.57.20 40168
db_bootstrap.ior
to manually write the correct host and port. But I
still get the same XmlDbException at the point of
acquiring a collection. One noteable is that when I
do use the fix utility to change the host, the client
will hang fo a couple of minutes before reporting the
same exception. My guess is that the port is not
correct since it is always changing.
