HTMLUnit and GWT

After developing on an other aspect of a project, I realized later that all my GWT testcases didn’t work anymore. I got the following strange Exception:

</clinit>

The exception also occurred via Maven and not only in IntelliJ, so I knew it has something to do with my Maven-Project.

After checking the dependencies of my project with mvn dependency:tree, I found a new transitive dependency of a new added dependency. Because I didn’t need the htmlunit-part of this component I excluded the htmlunit-dependency with the following directive in my pom.xml:

            </exclusion>
        </exclusions>
    </artifactid></groupdid></dependency>
....
</dependencies>

A deeper analysis of the problem shows, that the transitive dependency was too new, because the field FIREFOX_17 is not available any more, but the newer one like FIREFOX_38.

GWT-Hidden-Feature: code coverage

In July 2012 a until now rarely documented feature was added to GWT (related Git-Commit). It’s code coverage on the client side.

How it works

You can activate it via the System-Property “gwt.coverage”. The property-value must contain either all named Java source files separated by comma, or it must point to a text file containing all Java source files; one per line. Now the GWT compiler will instrument the corresponding JavaScript which is based on the named Java source files. Additionally the compiler registers an onUnLoad-Event, which stores the code coverage into LocalStorage of the browser.

Maven-Example

I have a simple GWT-Project which is build via Maven. In the main source (src/main/java/org/jajax/gwt/test/client/MyEntryPoint.java) I have the following file:

?View Code JAVA
1
2
3

package org.jajax.gwt.test.client;
 
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.Window;
 
public class MyEntryPoint implements EntryPoint {
 
   @Override
   public void onModuleLoad() {
       Window.alert("Hello world");
   }
}

Additionally I created a Textfile (target/gwt-coverage-sources.txt) with the following content:

?View Code PLAIN
1

org/jajax/gwt/test/client/MyEntryPoint.java

Now only the configuration of GWT is missing. You have to add the Parameter gwt.coverage=target/gwt-coverage-sources.txt.

?View Code XML

<plugin>
    <groupid>org.codehaus.mojo</groupid>
    <artifactid>gwt-maven-plugin</artifactid>
    <version>2.7.0</version>
    <configuration>
        <extrajvmargs>-Dgwt.coverage=target/gwt-coverage-sources.txt</extrajvmargs>
    </configuration>
</plugin>

Now if you run you application, you can access the code coverage via JavaScript

?View Code JAVASCRIPT
1

localStorge.getItem("gwt_coverage");

You will get a JSON with the following content:

?View Code JSON
1

{"org/jajax/gwt/test/client/MyEntryPoint.java":{"6":1,"10":1}}

The inner object has for every line as key a value of 0 for a missing coverage or 1 for covered code.

Conclusion

This feature is very interesting, because the alternatives are very rare. The old option to use Emma / Jacoco is not functional anymore with the current versions of Java (1.8), GWT (2.7.0 / 2.8.0-SNAPSHOT), etc. So this feature seems to be a good alternative. Unfortunately there is no tool to extract the code coverage of Unit-Tests or Integration-Tests, but I will release a Tool, which connects the GWT code coverage with Jacoco Reports. So stay tuned!

Java JBoss Maven

Get the right dependencies for JBoss 5 Client and Maven

The last days my task was to port a very complex JBoss-Application from JBoss 4.2 to 5.1.0 GA. The Application has a couple of EJBs and many logic (Stateless-Beans, Stateful-Beans, Service-MBeans, etc.), a complex Web-Application built on top of Seam 2.1 and some simple Java-Clients accessing the provided businesslogic as a JBoss Client.

The whole application is built with maven.

In the past I imported the jbossall-client.jar directly into my Maven Repository. But I thought JBoss.org provides the used JARs via the repository http://repository.jboss.org/maven2/. The right package would be:

?View Code XML
1
2
3
4
5

<dependency>
    <groupid>org.jboss.jbossas</groupid>
    <artifactid>jboss-as-client</artifactid>
    <version>5.1.0.GA</version>
</dependency>

But this sounds better as it really is. Because of the transitive dependencies of some used packages, nearly the whole JBoss-Server is included. The developers of the JBoss-Servers sometimes using classifiers instead of splitting a mega-jar into several sub-jars. For example the org.jboss.jbossas:jboss-as-server artifact.
One solution would be to repackage all needed JARs to one JAR.
For me the solution was to build my own jboss-as-client, using a self-made pom with all needed dependencies. Because this is more the maven-way. But what is needed? This is quite easy. I tried to find the correct artifacts of the jar-files which are referenced by the jbossall-client.jar, delivered with the JBoss 5.1.0 release.

All transitive dependencies are excluded, to avoid the described problem.

If you have any suggestions how to optimize it or if I have something missed, please let me know.

And here is the result:

Maven: “Error installing metadata”

Today I had a problem compiling and installing a simple maven project.
Every time I ran “mvn install” I received the following error:

Error installing artifact's metadata: Error installing metadata:
Error updating group repository metadata
input contained no data

The problem here was an empty maven-metadata-local.xml in my local repository of the artifact I wanted to install. After completely removing this artifact from my repository an install was possible.

Running classes via maven from console

If you use maven to compile and handle your applications, you may want to directly call it from console. Here you can use the Maven-Exec-Plugin. This plugin provides an easy method to execute Java-Classes. Of course you can configure the plugin as usual in you pom.xml, but you also can directly use it from the console.

To run a simple class you can use:

?View Code BASH
1

mvn exec:java -Dexec.mainClass=info.javahelp.examples.Example

The advantage is that java is correctly called with all used jar-dependencies and the resulting classpath.

To affect the used dependencies you can also define the used scope (default: compile). For example your application is in testing scope you can run it with:

?View Code BASH

mvn exec:java -Dexec.mainClass=info.javahelp.examples.tests.Example -Dexec.classpathScope=test
