The problem you seem to have is that the server JARs are not present in your WAR. It's difficult to say why without more information. Let's have you start by showing the output of

Code:

mvn package

Note also, you seem to be starting to develop something new on a very obsolete version - that's not something we support, so if this is new development, please update to 12.1.

Dear Isomorphic, thanks for the quick answer!

I run that command and this is what I get:

There are a few problems with this POM, but none that are obviously the root cause given what information we currently have. Do you see isomorphic-core-rpc.jar and isomorphic-sql.jar in your target's WEB-INF/lib directory? It looks like that would be at D:\Development\Repos\Git\Java\Samples\SamplesSGWT\target\SamplesSGWT\WEB-INF\lib.

The easiest thing to do by far would be to get a current version of the framework and create your sample project using an archetype, as described in the mavenSupport documentation topic. This will save you a lot of trouble, and as previously stated, you are using an obsolete version of the framework anyway.

Otherwise, our best suggestion at this time is to remove all unnecessary elements from your POM until `mvn package` creates a WAR with the correct content. In your case, you can probably replace the entire build section with a simple gwt compile step.

Code:

<build>
        <plugins>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>gwt-maven-plugin</artifactId>
                <version>${gwt.version}</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>compile</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

Do note that the codehaus plugin is also obsolete though. Consider migrating to its replacement.
