Re: [INTERFACES] JServ + PostgreSQL 6.3

Two thoughts.

The servlet code would help a fair bit in this instance. I've got the identical
setup running quite successfully with multiple servlets on a Linux box. So I
know there is a solution.

Second, the socket is locked either by another process, or another previous
instance of ther servlet running. I think the /tmp file messages may be
secondary exception traps at higher levels, depending on the code. ie: the
exception is dropping through, and/or being rethrown after the failed bind, or
the fail to bind triggers a cascade of errors in the coding assumptions
afterwards.

The checkVersions program isn't part of the 1.1.6 distribution, so I assume you
have a class loading at runtime or some such thing. Again, the source would
help, but the path it references on the class would *not* be permitted to be
accessed by the servlet for loading from the .conf file you included from what I
understand the setup to be. The binary is/is in /usr/local/java/bin/java, and
the classpath for loading is in the subs of jserv, or the standard lib
classes.zip. How is checkVersion being called/implemented?

Like I say, I know the solution is there, but I need a bit more info to help you
get to it! :-)
