Running Java classes from multiple IFS

We have an AS400 with three partitions.

Partition 1 is primarily used for development and has an IFS structure. 
It also has the Java development system installed, and contains all the 
Java classes.
All application successfully run in this partition

Partition 2 is the production environment and it has it's own separate 
IFS, with currently no JVM installed. 
We want to install Java in partition 2 but want to avoid having to have 
duplicate all the Java classes we create in partition 1, into partition 2, 
rather we want to be able to access the Java classes from partition 1.   I 
can see someone forgetting to copy the most current Java class from 
development into production.

If we install the JVM on partition 2, can we access the Java classes and 
other jar files located on partition 1, without having
to have a second copy of all the classes and related jar files in 
partition 2.

My thoughts were to try and create a link to the IFS system in partition 1 
and set the class path to point to this link.

Can multiple IFS structures be linked to commonly share Java objects?
