Hi all, is it possible to cache static images and .js files in Tomcat? (I'm

Moral of the story is the error message is pretty clear. If your class
has imported javax.activation.* and javax.sql.*, you may have to be more
specific on the type of your datasource variable:
Exception has taken place here:
DataSource ds = (DataSource) ctx.lookup(java:comp/env/jdbc/bzk2);

Ok... so what do the import statements at the top of that file look
like? Seems to me java has taken DataSource to mean
javax.activation.DataSource instead of javax.sql.DataSource. That's
probably because of the imports at the top of your source file.
