Yes java is compiled, and compilers do catch most syntax and scope 
errors, as I said,
but the java object code is still interpreted. Logical errors and other 
mistakes still get
through compilation, and good regression testing is still required for 
quality assurance.

I think JSP is an excelent solution and is probably the way I will go. 
We already have
Jakarta Tomcat running inhouse, but I havn't touched Java since 1996.

I started with PHP about a year ago and after 1 week I had succefully 
written a radius
authentcated session based PostGreSQL reporting application. A couple 
months ago I
wrote a data collection application that stores data in a MySQL database 
{yik, not my
choice} and a PHP front end that generates tables graphs and statistical 
analysis, and it
took one day to build and test thoroughly.

I used to use Perl or white my own CGI's in C, but PHP is so, much 
easier than either.
I have been programming since 1981 and have learned many languages on many
platforms. I have maintained a few Sun servers but usualy in a mix with 
other Unix
variants. Because of the mixed environments and poor Java support on 
many platforms
I never had a good reason to use java. Most of the applications I have 
written did not
need complicated GUI interfaces, so C and Perl have done fine for a long 
time, and
PHP is adequate for simple DB applications. I am entertaining JSP for 
the more
complicated GUI interface for a project I may need to build in the near 
future.
Management has asked about ASP, but since we have to support many non 
windows
platforms I have strongly advised against it, besides I feel JSP will be 
much better.

Do you have a suggestion for a good resource, in order for me to get up 
to speed
quickly with Java?
