SAS 9.1.3 uses the sas.app.class.path property for obtaining the the class
path to be used by JavaObj.

sas.exe ..... -JREOPTIONS (-Dsas.app.class.path={myClassPathForJavaObj})

Here is the full TS response to my JavaObj class path questions
<quote>
I ran your Example1.java program with this command line and it worked as I
would have expected:

sdssas -t dev/mva-v913sp3 -dms -jreoptions (-Dsas.app.class.path=C:\jstuff)

java.class.path and sas.app.class.path are not the same Java option.  When
you set sas.app.class.path,  java.class.path will not change.  Currently
javainfo doesn't show that sas.app.class.path has been set; this is being
addressed as a defect.

A single list of arguments/jreoptions is built and passed on to the JVM.  If
duplicate options appear in the list, the JVM will honor the last one it
sees. This list is built from the "-jreoptions" options appearing on the
command line and the jreoption values appearing in the SAS config file.

The hierarchy of how the jre options are set:
1) datastep or proc jcall uses environment variable value
2) command line option \
3) config file         /
if proc javainfo is run first, then command line opts, if no command line
opts then config file opts are used.

As of right now, the expected SAS 9.2 release date is around March 2007.

Testing of my prior JavaObj projects finds that the property
sas.app.class.path indeed does prepare the proper classpath for JavaObj
(when either JRE 1.4 or 1.5 installed).
