Java UnsatisfiedLinkError exception when connecting to Postgresqldatabase

Hello;

I've written a Java program which uses Postgresql via JDBC.  The program works fine on all RedHat systems I've tested
exceptone, where it yields an UnsatisifiedLinkError.  Here is the stack trace:
 

sun.misc.VM.latestUserDefinedLoader0(Native
Method)
sun.misc.VM.latestUserDefinedLoader(VM.java:411)
java.io.ObjectInputStream.latestUserDefinedLoader(ObjectInputStream.java:2351)
java.io.ObjectInputStream.resolveClass(ObjectInputStream.java:686)
java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1866)
java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1749)
java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:2040)
java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1571)
java.io.ObjectInputStream.readObject(ObjectInputStream.java:431)
org.postgresql.ds.common.BaseDataSource.readBaseObject(BaseDataSource.java:1210)
org.postgresql.ds.common.BaseDataSource.initializeFrom(BaseDataSource.java:1220)
org.postgresql.ds.PGPoolingDataSource.initialize(PGPoolingDataSource.java:267)
org.postgresql.ds.PGPoolingDataSource.getConnection(PGPoolingDataSource.java:324)

Any ideas?

Thanks in advance.

Hmm.
So what was the UnsatisifiedLinkError message, before the traceback above?

Ah ha, that's it.  Part of the deployment on the problem system was outdated.

Thanks to all.
