Exceptions after unchecking "Use Google AppEngine"

[Magnus]

Hello,

after unchecking "Use Google AppEngine" in the project properties in
Eclipse, I get the following exceptions when launching the
application.

(I did so, because I found a solution for my database problem:
http://www.mail-archive.com/google-we...@googlegroups.com/msg14715.html)

Can you help?

Thank you
Magnus

Hello,

for all those who have problems connecting to a mysql database within
a RPC call:
The solution found in this thread is to uncheck "Use Google AppEngine"
in the eclipse project settings:
http://www.mail-archive.com/google-we...@googlegroups.com/msg14413.html

But this leads to problems when running the app in hosted mode.

My (unsatisfactory but working) approach:
Create a new Web Application Project, where AppEngine is unchecked at
project creation.

I hope this will be usefull for someone...

Magnus

The (probably satisfactory) approach is to remove the GAE jars from the classpath. When you uncheck GAE, it doesn't remove the jars from the classpath. There is some kind of version mismatch in one of the jetty classes (as shown by NoClassDefFoundError), so when you remove GAE jars, things work fine.

Filed the following issue for this:

I'm having exactly the same problem, but i didn't get the clue on how
to solve this one.
Should i remove some files which are in the "war\WEB-INF\lib"
directory? If yes, which ones should stay/be removed?

The application is an "extended" example with additional mysql
connection. I've unchecked the mentioned option because i was unable
to get the MySQL Driver working.
I had this Exception before unchecking:
Caused by: java.lang.ExceptionInInitializerError
at
com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:
282)
at java.sql.DriverManager.getConnection(Unknown Source)

Currently the following files are in the lib directory:

appengine-api-1.0-sdk-1.3.4.jar
appengine-api-labs-1.3.4.jar
appengine-jsr107cache-1.3.4.jar

Yes, remove everything except gwt-servlet and mysql jars.
