Weld, GWT and ErraiBus project template?

[slawek t]

Hi, I'm thinking about good eclipse (with maven, ant?) template for project based on Weld, GWT 2 and ErraiBus. Ideally would be to have possibility to use GWT plugin for quick GWT development, but in the same time have well  incorporated WELD (and ErraiBus) with maven (or ant) to build and deploy whole project. All deployed on JBoss AS 6.0.0-m3.

Any advise would be very helpful.

I think the best fit at the moment is the GUI example that resides with the weld integration codebase:

http://anonsvn.jboss.org/repos/errai/projects/weld-integration/trunk/examples/gui/

This should work with the eclipse GWT plugin. I am planning on turning this into

a maven archetype for the 1.1-FINAL release, which is due soon.

Would that work for you?

[Heiko Braun]

I've created a preliminary archetype:

 mvn archetype:generate \
        -DarchetypeGroupId=org.jboss.errai \
        -DarchetypeArtifactId=cdi-archetype \
        -DarchetypeVersion=1.0-SNAPSHOT \
        -DarchetypeRepository=https://repository.jboss.org/nexus/content/groups/public/

Would be nice if you could tell if it works for you. We'll base the archetype that ships with the next release on this one.

I've added the eclipse setup instructions to the Wiki:

https://community.jboss.org/wiki/WorkingwithGWTCDIandErrai

Most notable is probably the fact that you need to modify the GWT plugin launch configuration,

so that the CDI container get's bootstrapped in GWT hosted mode.

Hi Heiko,

Today I've prepared project template according to newest description here: https://community.jboss.org/wiki/WorkingwithGWTCDIandErrai

My environment: java jdk 1.6, eclipse 3.6, GWT sdk 2.0.4, maven 2.1. Building project template from maven archetype went correctly, import into eclipse correctly (at least with no errors), final building in eclipse with maven also OK, but Run (Run As ...) with Jetty launcher ended with error:

What can I do to fix the issue with Jetty launcher?

[Heiko Braun]

Are you using 1.1-Final already?

[slawek t]

I hope so. I completely removed maven repo befor starting, so I understand I received newest version of Errai.

Currently in my maven repo for Errai (.m2\repository\org\jboss\errai\) is:

cdi-archetype

errai-bus

errai-parent

errai-common

errai-ioc

errai-cdi

cdi-integration-parent

errai-cdi-jetty

cdi-archetype/1.1-Final

errai-bus/1.1-Final

errai-parent/1.1-Final

errai-common/1.1-Final

errai-ioc/1.1-Final

errai-cdi/1.1-Beta2

cdi-integration-parent/1.1-Beta2

errai-cdi-jetty/1.1-Beta2

Is it correct?

Slawek

[Heiko Braun]

yes, looks good.

i need to reproduce the error locally. I'll get back to you soon.

[Heiko Braun]

https://jira.jboss.org/browse/ERRAI-115

[slawek t]

Thanks

[Heiko Braun]

Ah Slawek, I should have read stacktrace more carefully. It's actually the same problem we had with the new eventing code. The CDI bootstrap process scans the GWT client code and attempts dependency injection on it:

at injection point [[parameter 1] of [constructor] @Inject public pl.termeet.client.App(MessageBus)]

I've published a new CDI integration snapshot. If you change your org.jboss.errai:errai-cdi to 1.1-SNAPSHOT, the problem should be gone.

Make sure that eclipse picks up the changes.

[slawek t]

I tried to follow your suggestion but there is probably something wrong with maven repository location org/jboss/errai/errai-cdi/1.1-SNAPSHOT. Maven can't download libraries from that location (probably due to issue with maven-metadata.xml).

[slawek t]

Heiko, could you give me more details how to change errai-cdi from version 1.1-Final to 1.1-SNAPSHOT please? I'm quite new to maven and I'm afraid I do it incorrectly.

[Heiko Braun]

just take a look at the pom.xml. The version is configured somewhere under <properties/>

[slawek t]

That's the part of pom.xml of my project (created on base of archetype):

   <properties>

        <webDescriptor>jetty</webDescriptor>

if I change

<errai-cdi.version>1.1-Beta2</errai-cdi.version>

to

<errai-cdi.version>1.1-SNAPSHOT</errai-cdi.version>

I receive:
