RE: [OpenMap Users] Java 1.4.0_02 Problems

Based on a search on the error in non-OpenMap areas it looks like it might be
trying to create a file in the /etc/.java directory.

Try creating that directory and making sure you have read/write Privileges.

Prakash,

I tried this modification, and was met with the same result.

in tcsh:

setenv OPENMAP_HOME <my home directory path>/openmap-4.5.3
setenv CLASSPATH ${OPENMAP_HOME}:${OPENMAP_HOME}/lib/openmap.jar

java -Dopenmap.configDir=${OPENMAP_HOME} com.bbn.openmap.app.OpenMap

Note: my openmap.properties is sitting in $OPENMAP_HOME.

I get the following output:

OpenMap(tm) Version 4.5.3

  See http://openmap.bbn.com/ for details.

Oct 15, 2002 7:46:24 AM java.util.prefs.FileSystemPreferences$2 run
WARNING: Could not create system preferences directory. System
preferences are unusable.

It appears to be related to something different. Thanks for the idea,
though!

Regards,

Eliot
