Note : iText 1.2 is more than 6 years old. You should NOT expect any kind of
compatibility between this obsolete version and the latest one.

Current versions of iText work fine with Java 5 and later. However, the
exception you get tends to indicate that some old version of iText is still
in your classpath, instead of the most recent one.
My piece of advice : try to build a standalone version of you application,
fix your classpath, and then run it through an application server. Life will
be far easier...
