Compilation problems with Errai 2.0.0.Final

htfv May 10, 2012 4:55 AM

Hello World!

I'm getting exceptions like the following when I build my project:

[INFO] INFO [RpcProxyLoaderGenerator] generating rpc proxy loader class.

Sometimes it occurs for other classes. Here's the source of MediaSearchRequest:

package com.brandmaker.research.ng.gwt.shop.shared.search;

import org.jboss.errai.common.client.api.annotations.Portable;

@Portable
public class MediaSearchRequest
{
    private String query;

    public String getQuery()
    {
        return query;
    }

    public void setQuery(String query)
    {
        this.query = query;
    }
}

What am I doing wrong?

Regards

I have 3 GWT modules in my project, but only one of them has an entry point. The problem disappeared when I excluded modules without entry points from compilation.

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>gwt-maven-plugin</artifactId>
    <version>${dependencies.gwt.version}</version>
    <configuration>
        ...
        <modules>
            <!--module>com.brandmaker.research.ng.gwt.layout.Layout</module-->
            <module>com.brandmaker.research.ng.gwt.shop.Shop</module>
            <!--module>com.brandmaker.research.ng.gwt.widgets.Widgets</module-->
        </modules>
        ...
    </configuration>
    ...
</plugin>

Hi,

These errors mean that the GWT compiler couldn't find the sources of the classes MediaInfo and MediaSearchRequest. When you package your modules, make sure you include the source files in your jars.

Cheers,
Christian

It's all in the same Maven module, I cannot understand why it cannot find sources.

GWT by default assumes that client-side classes reside in the .client package or below. This doesn't seem to be the case in your app. Did you specify an alternative source path in your gwt.xmls? If not, then that's what's missing:

<source path='shared'>

All our demos use client.local, client.shared, so that this configuration is not neccessary.

unzip the jar or war that your Maven module creates and make sure that the sources and gwt.xml files are there. if not you may need to add this to your <build> configuration for your Maven Module:

        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.java</include>
                    <include>**/*.gwt.xml</include>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource>
                <directory>src/main/resources</directory>
                <includes>

I specified the source paths, see below. I don't know if it relates, but there were no problem in dev mode.

Shop.gwt.xml

<module rename-to="shop">

    <inherits name="com.brandmaker.research.ng.gwt.layout.Layout" />
    <inherits name="com.brandmaker.research.ng.gwt.widgets.Widgets" />

    <inherits name="com.google.gwt.activity.Activity" />
    <inherits name="com.google.gwt.place.Place" />

    <inherits name="org.jboss.errai.bus.ErraiBus" />
    <inherits name="org.jboss.errai.enterprise.CDI" />
    <inherits name="org.jboss.errai.ioc.Container" />

    <source path="client" />
    <source path="shared" />

</module>

Widgets.gwt.xml

<module rename-to="widgets">

    <inherits name="com.google.gwt.user.User" />
    <inherits name="com.google.gwt.user.theme.standard.Standard" />

    <source path="client" />
