Working with modules on the local dev server for Java

Question

I am developing a Google Appengine Java application and I am facing a major challenge testing with the local dev server. I dumped the Eclipse tools cause I'm more flexible with Netbeans and I am using Appengine Maven plugin for my development.

This is my sample project structure :

myapp
   module-endpoints
   module-web
   module-ear
   pom.xml

The application works when I build with mvn clean install on the root folder(myapp) and also when I use the mvn appengine:devserver command to run the module-ear application, however I can't seem to access the cloud endpoints via http://localhost:8080/_ah/api. I can only access the endpoint's API via the dynamically issued port when I access it via the admin console http://localhost:8080/_ah/admin.

The issue with this is that when testing cloud-endpoint Javascript client on the module-web project according to tutorials I am supposed to use localhost:8080/_ah/api as my url to test. Am I missing something?

If the question is still actual you could always update your pom.xml with flags so that the ports of all your modules are defined:

<plugin>
    <groupId>com.google.appengine</groupId>
    <artifactId>appengine-maven-plugin</artifactId>
    <version>${appengine.target.version}</version>
    <configuration>
      <port>8080</port>
      <jvmFlags>
        <jvmFlag>-Xdebug</jvmFlag>
        <jvmFlag>-Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n</jvmFlag>
        <jvmFlag>-Dcom.google.appengine.devappserver_module.mymodule2.port=9090</jvmFlag>
      </jvmFlags>
      <disableUpdateCheck>true</disableUpdateCheck>
    </configuration>
  </plugin>

Then you could use localhost:9090/_ah/api/explorer to test your APIs

If you have several modules deployed, you need to update your maven app engine launcher setup to recognize the different modules. See the modules sample Java app at https://github.com/GoogleCloudPlatform/appengine-modules-sample-java.

If you've already done that, then a dispatch.xml file will tell app engine how to route requests: https://cloud.google.com/appengine/docs/java/modules/routing
