Java Postgresql Runtime Error

I have a couple of java applications that use a postgres database. They have worked fine on many computers, but I have come across 1 computer that is throwing a runtime error. I have double and triple checked my database configurations and haven't been able to find an error.

The code that I run that throws the error is:

this.connection = DriverManager.getConnection(this.connectionStr,
                    this.username, this.password);

where this.connectionStr is previously set to be

this.connectionStr = "jdbc:postgresql://" + this.server + ":"
                + this.port + "/" + this.database;

I am not sure where to go from here. Any help would be great.

The runtime error is as follows where PostgresHandler.java:70 is the code I showed above.

Check your classpath, be sure that the driver jar is installed on the problem server/host.

A reflection error usually means you misspelled a class name, or forgot to add the library with the class. Not that I've ever done that :-)

Alternately, maybe you have an older version of the driver that does not fully implement a newer interface???

Looks like you are using Eclipse's jar-in-jar loader. Have you tried running this with the first level JAR file exploded?

If that works, something is going on with un-jaring multiple levels of a jar file. The only thing I can think that would cause that is a virus scanner.

My guess is that you are running a pre 5.0 version of the JVM. The version of the jar you are using depends on StrictMath which came in at 5.0. Are you using a 1.4 jvm?
