    Need help on making my first errai app

    stab

      Hi,

       

       

      Newbie in Errai and Maven and quite new in java too(former Delphi developer).

       

      I'm using eclipse helios on windows xp and downloaded errai-cdi-1.3.0.CR1.zip

       

      Tried to follow the instrctions given in:Working with GWT, CDI and Errai by Heiko Braun

       

      - imported the TagCloudDemo to geta a maven build structure

      - got to step 4c and guessed that the configuration I was supposed

        to modify is Web Application -> index.html

      - disabled Server -> Run built-in-server

      - changed Arguments:

        -noserver -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -startupUrl index.html -logLevel

        INFO -codeServerPort 9997 -war C:\eclipse-java-helios-SR2-win32\eclipse\plugins\

        ServerPush\errai-cdi-1.3.0.CR1\examples\errai-cdi-tagcloud-demo\war

       

        to

       

        -server org.jboss.errai.cdi.server.gwt.JettyLauncher

        -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -startupUrl index.html -logLevel

        INFO -codeServerPort 9997 -war C:\eclipse-java-helios-SR2-win32\eclipse\plugins\

        ServerPush\errai-cdi-1.3.0.CR1\examples\errai-cdi-tagcloud-demo\war

       

      - applied changes

      - run

       

      and got an messagesbox: Errors exists in required project(s)....

      proceeded anyway and got error:

      Missing required argument 'module[s]'

      Google Web Toolkit 2.3.0

      DevMode [-noserver] [-port port-number | "auto"] [-whitelist whitelist-string] [-blacklist blacklist-string] [-logdir directory] [-logLevel level] [-gen dir] [-bindAddress host-name-or-address] [-codeServerPort port-number | "auto"] [-server servletContainerLauncher[:args]] [-startupUrl url] [-war dir] [-deploy dir] [-extra dir] [-workDir dir] module[s]

       

      where

        -noserver        Prevents the embedded web server from running

        -port            Specifies the TCP port for the embedded web server (defaults to 8888)

        -whitelist       Allows the user to browse URLs that match the specified regexes (comma or space separated)

        -blacklist       Prevents the user browsing URLs that match the specified regexes (comma or space separated)

        -logdir          Logs to a file in the given directory, as well as graphically

        -logLevel        The level of logging detail: ERROR, WARN, INFO, TRACE, DEBUG, SPAM, or ALL

        -gen             Debugging: causes normally-transient generated types to be saved in the specified directory

        -bindAddress     Specifies the bind address for the code server and web server (defaults to 127.0.0.1)

        -codeServerPort  Specifies the TCP port for the code server (defaults to 9997)

        -server          Specify a different embedded web server to run (must implement ServletContainerLauncher)

        -startupUrl      Automatically launches the specified URL

        -war             The directory into which deployable output files will be written (defaults to 'war')

        -deploy          The directory into which deployable but not servable output files will be written (defaults to 'WEB-INF/deploy' under the -war directory/jar, and may be the same as the -extra directory/jar)

        -extra           The directory into which extra files, not intended for deployment, will be written

        -workDir         The compiler's working directory for internal use (must be writeable; defaults to a system temp dir)

      and

        module[s]        Specifies the name(s) of the module(s) to host

       

      What am I doing wrong?

       

      Regards

          Here are the program arguments for starting the TagCloudDemo using an Eclipse Run Configuration:

           

          {code}org.jboss.errai.cdi.demo.tagcloud.TagCloudDemo -startupUrl TagCloudDemo.html -server org.jboss.errai.cdi.server.gwt.JettyLauncher{code}

           

          Also you need to add your source folder (src/main/java) to the Run Configuration's classpath.

           

          You can also take a look at our quickstart guide and use our maven archetypes to get started: https://docs.jboss.org/author/display/ERRAI/CDI+Quickstart+Guide

            Hi again,

             

            Followed your quickstart guide and used the archetype specified as:

             

            mvn archetype:generate \

            -DarchetypeGroupId=org.jboss.errai.archetypes \

            -DarchetypeArtifactId=cdi-quickstart \

            -DarchetypeVersion=1.3.0.CR1 \

            -DarchetypeRepository=https://repository.jboss.org/nexus/content/groups/public/

             

            with local properties like:

             

            groupId : foo.bar

            artifactId : gwt-app

            version : 1.0-SNAPSHOT

            package : com.foo.bar

             

            As explained in the guide a great amount of jars was downloaded to local repository and

            it all succeded as:

             

            Confirm properties configuration:

            groupId: foo.bar

            artifactId: gwt-app

            version: 1.0-SNAPSHOT

            package: com.foo.bar

            After that I tried to follow the instructions in Errai WIKI:

              Working with GWT, CDI and Errai

            and verified that I have eclipse, GWT 2.3.0 and m2e 1.0.100.20110804-1717 are installed

             

            next step was to import the gwt-app into eclipse

            Import1.gif

            selected root folder

             

            selecte root folder.gif

             

            Import2.gif

            clicking next displayed

             

             

            Import3.gif

             

            Clicking finish gave:

             

            Import4.gif

            What is wrong and what and where should I fix?

             

            Advancing to step 4d, applying disabled built-in server and program arguments like:

             

            programargs.gif

            and then running gives:

              To handle the first problem (no eclipse plugin found for the gwt-maven-plugin) add the following to your pom.xml under <build>:

               

              {code:xml}

              <pluginManagement>

                 <plugins>

                   <plugin>

                     <groupId>org.eclipse.m2e</groupId>

                 </plugin>

              </plugins>

              </pluginManagement>{code}

               

              This is a new issue with M2E which we will handle with the next release of our archetypes.

               

              Also, execute a "mvn clean gwt:run" on the command line which should start DevMode/Jetty. If that works, you should be able to start the app from within Eclipse.

                  No only in the last build section, outside the profiles. This is just for eclipse to ignore the missing plugin.

                    Hi again,

                     

                    Starting to work.

                     

                    When I issued: mvn clean gwt:run jar and pom download started again and I recognized some errors but anyhow a standalone

                    window "GWT Development Mode" showed up, clicked button "Launch Default Browser" and the errai-app was up and running.

                     

                    Very nice function, but could you tell how I start dev-mode from within eclipse.

                    What am I supposed to assigned to "argument" when I run run configuration?

                      You can either use the Google/GWT plugin for Eclipse or just create a runtime configuration using com.google.gwt.dev.DevMode as main class and provide the program arguments I posted above.
