Actually, I've run numerous comparisons of Java, SQL and RLA over the years,
and Java has lost soundly in every one.  Been awhile since I did one,
though, so perhaps it's time to revisit it.  However, are you suggesting
that Java is as fast as RPG and native I/O for database access?

Blair, the original post had to do with writing Java applications that would
mimic exiting RPG legacy applications.  All my comments were based on that
statement.

I agree that Java is the proper language for the UI middleware required for
web applications, but I still haven't seen a Java-based iSeries application
that can compare to RPG and native DB2/400 access for business logic.

I will once again post my yardstick:

Show me an MRP generation over a 10,000,000 record database that comes
within, say, 50% of the performance of the equivalent program in RPG.  At
that time, Java will have come of age for business logic.  The last time I
published benchmarks, Java was nowhere close - heck, embedded SQL didn't
even run as fast, so I know Java wouldn't if it used JDBC.  And my RLA
benchmarks didn't show a lot of promise, either.  Times may have changed,
but it's up to the challenger to provide the proof, I think.

But that's just MY opinion.
