RE: Deadlock calling NCARG from Apache Tomcat

Hey folks,

Has anyone seen a similar problem before or know where I can get some
help? I posted this a couple weeks back and didn't see any replies.

Subject: Deadlock calling NCARG from Apache Tomcat

Hi, I'm brand new to this list. I'm currently working for NASA on a
small exploration project involving visualizing science data on maps.
Our main application is in Java running in the Apache Tomcat application
server but we implemented the visualization portion in C that calls the
NCAR Graphics package. The visualization utility works find from the
command line but locks every time when we run it from Tomcat/Java. I
have code in place to read and flush the input and error buffer streams
but that didn't fix the locking problem. As anyone else every had
similar problems between NCARG and Java or Tomcat? BTW, I've verified
that the NCARG_ROOT and PATH properties are defined correctly.
