Did you bring in the new jquery.jmesa.js file to your project?
Also, what are you trying to do? Just curious if there is some better advice I could give.
it seems there are a lot of deprecated methods in the Java part as well as in Javascript
Yes, I tried to make the 3.0 version as backwards compatible as I could. In my own apps we were running both the old and new versions for quite a while. In January I am starting work on the 4.0 version of JMesa. The the first thing I plan on doing is removing all the deprecated methods so it is best to get things working with 3.0.
