Re: java.lang.ClassNotFoundException: javax.sql.DataSource when using GWT 2.9.0 + Java 11 combination
I take back what I said. It seems there are classpath resolution issues when using a custom "JettyLauncher" while running under "GWT Eclipse Plugin", probably due to different classloaders assignment. I am afraid the time has finally come to abandon use of DevMode and the "GWt Eclipse Plugin", until this is fixed in later versions of GWT. I hope a future version of GWT will make use of a Jetty version supporting a more elegant way to override the "allowedFromSystemClassLoader" variable.

Overriding JettyLauncher with "javax.sql." on the "allowedFromSystemClassLoader" variable has worked for me on a variety of projects, using SuperDevMode + GWT 2.9.0 + JDK 11 I hope a future version of GWT will make use of a Jetty version supporting a more elegant way to override the "allowedFromSystemClassLoader" variable.

Re: java.lang.ClassNotFoundException: javax.sql.DataSource when using GWT 2.9.0 + Java 11 combination
Yes it seems that you need to run it in a separate servlet container, but it doesn't have to be Tomcat. You can use Jetty so long as it is fairly recent (unlike the old version embedded in GWT dev mode).

Re: java.lang.ClassNotFoundException: javax.sql.DataSource when using GWT 2.9.0 + Java 11 combination
I am not sure if it is the same issue but when I switched to Java 11 I had the following: "Server class 'javax.sql.DataSource' could not be found in the web app, but was found on the system classpath [ERROR] Found resouce but unrecognized URL format: ' jrt:/java.sql/javax/sql/DataSource.class <http://jrt/java.sql/javax/sql/DataSource.class>'" In according to https://github.com/gwtproject/gwt/issues/9582 there is an issue with JettyLauncher. And it is recommended to use "CodeServer and a separate servlet container." Here is a discussion on Jetty in GWT: https://groups.google.com/g/google-web-toolkit-contributors/c/iU9hckIab2o?pli=1 . It means that one needs to run the application under Tomcat (a separate servlet container) instead of the embedded Jetty.

Re: java.lang.ClassNotFoundException: javax.sql.DataSource when using GWT 2.9.0 + Java 11 combination
Without being able to see the project setup this is tough to answer. However regardless of the exception you are seeing: Classic/Legacy DevMode will not work with GWT 2.9.0 correctly, because GWT 2.9.0 already uses JsInterop internally in its Java SDK emulation (e.g. java.util.Date uses it). JsInterop is not supported by classic/legacy DevMode. With GWT 2.9.0 you have to use SuperDevMode to have a functional Java SDK emulation during development. -- J. abhiy...@gmail.com schrieb am Mittwoch, 29.

Hi, as you are saying, if it worked for couple of times and then not, then I guess the exception is not mapped correct. Do you have enough free memory on the machine? Try restarting the machine...if this helps and after time the exception appiar again then is a machine problem(memory etc..).

Re: OOPHM r4218: java.lang.ClassNotFoundException: com.google.gwt.user.client.rpc.RemoteService
Thanks for the reply. First, this problem did not happen in GWT 1.53. It only happens on OOPHM branch. I believe the WAR includes jar correctly. Attached is my web.xml.

Re: No source code is available for type java.lang.ClassNotFoundException; did you forget to inherit a required module?
If you are including external source code (such as in the form of a Jar file), you will need to include that jar file in your Java CLASS_PATH and you will also need to edit your .gwt.xml file to inherit information from the included jar. The best way to do this is to add $APPDIR/externalcode.jar in the -cp option in the YourProject-shell and YourProject-compile scripts. After this, edit YourProject.gwt.xml file and add a line like this... inherits name='com.thapar.gwt.user.ui.SimpleSortableTable (this was an example of how to include a SortableTable from http://psthapar.googlepages.com/simplesortabletable).

Problem with java.lang.ClassNotFoundException only when deployed
Hi all,
First off, I am a new user and have built a very simple application.
It works fine under hosted mode. It compiles with no errors. When I
deploy it to the web server and point a browser at it, it throws a
ClassNotFoundException. I suspect this is a really simple problem
(probably caused by a really stupid error). This is driving me crazy
and I would really appreciate ANY help or suggestions anyone could
throw my way.
I have included a lot of error logs, copies of web.xml, directory
structures etc. below.
Trying to work through this is a learning experience, but I am
stumped. The fact that the server is able to sort out the URL sent
from the client enough to know the name of the object is
ca.KeithFuller.server.CorpusServiceImpl suggests to me that the server
is finding the web.xml file, which suggests that it should be able to
find the object since I believe that WEB-INF/classes is always on the
search path. The file CorpusServiceImpl.class is in WEB-INF/classes,
and the corresponding java file starts with:
package ca.KeithFuller.server;
import java.util.*; // for Scanner
import java.io.*;// for println
import ca.KeithFuller.client.CorpusSearchReturns;
import ca.KeithFuller.client.CorpusSearchService;
import com.google.gwt.user.server.rpc.RemoteServiceServlet;
public class CorpusServiceImpl extends RemoteServiceServlet
implements CorpusSearchService
{
...
A whole pile of details follow:
I use GWT 1.4.61
I use Eclipse 3.2.2
My webserver uses Linux, Tomcat and Apache.
I use FireFox 3.0.1 and the URL is
http://www.keithfuller.ca:9108/CorpusSearch/CorpusSearch.html
The client code contains:
...
// Create the proxy object
final CorpusSearchServiceAsync serviceProxy =
(CorpusSearchServiceAsync)
GWT.create(CorpusSearchService.class);
// Cast the proxy object to ServiceDefTarget
String serviceUrl = GWT.getModuleBaseURL() + corpus-search;
// if (GWT.isScript()){
// serviceUrl = /corpus-search;
// }
((ServiceDefTarget)serviceProxy).setServiceEntryPoint(serviceUrl);

Re: Problem with java.lang.ClassNotFoundException only when deployed
Hi Keith,
Looking at your deployment structure:
The web server has the directory structure:
apache-tomcat-5.5.25/webapps
CorpusSearch
... a pile of html, rpc, js, html, css, and...
web.xml
WEB-INF
classes
CorpusSearch.class
CorpusSearchReturns.class
CorpusSearchServiceAsync.class
CorpusSearchData.class
CorpusSearchService.class
CorpusServiceImpl.class
web.xml
lib
gwt-servlet.jar
web.xml
the package structure ca.KeithFuller.server seems to be missing which
would explain why you get a ClassNotFoundException for
ca.KeithFuller.server.CorpusServiceImpl. I think you should copy the
entire directory structure under WEB-INF\classes.
Also I would recommend you take a little time to make an Ant build
script that creates a WAR file for you application and copies it
straight to your Tomcat deployment directory where it will
automatically redeploy. This will kill problems like this (because Ant
doesn't make mistakes) and save you a lot of time in the long run.
There are lots of examples of how to do this in the group - just
search for ant build WAR.

Hi Gregor,
Yup, that fixed it. Stupid newbie error - fortunately the sort of
error that only gets made once. Now I can start putting back in the
server functionality that I took out to debug it.
Thank you very much for your help,

My webserver uses Linux, Tomcat and Apache.
I use FireFox 3.0.1 and the URL
ishttp://www.keithfuller.ca:9108/CorpusSearch/CorpusSearch.html
The client code contains:
...
// Create the proxy object
final CorpusSearchServiceAsync serviceProxy =
(CorpusSearchServiceAsync)
GWT.create(CorpusSearchService.class);
// Cast the proxy object to ServiceDefTarget
String serviceUrl = GWT.getModuleBaseURL() + corpus-search;
// if (GWT.isScript()){
// serviceUrl = /corpus-search;
// }
((ServiceDefTarget)serviceProxy).setServiceEntryPoint(serviceUrl);
...
The localhost.2008-09-18.log file contains:
Sep 18, 2008 10:21:04 AM org.apache.catalina.core.ApplicationContext
log

Re: java.lang.ClassNotFoundException
This is not a compile problem. You have not deployed the service classes to your web container properly.
