What's the minimum classpath for an Axis2 client?

Question

I want to build an Axis2 client (I'm only accessing a remote web service, I'm not implementing one!) with Maven2 and I don't want to add 21MB of JARs to my project. What do I have to put in my pom.xml to compile the code when I've converted the WSDL with ADB?

Answer 1

I am afraid you need to distribute almost all the jars, even if it is for a client only. I remember trying to find that out myself and soon gave up after too many Runtime ClassNotFound exceptions.

For more light-weight clients you may consider CXF.

Answer 2

(Note: This response was provided by Aaron Digulla himself. What follows is the exact text of his own answer.)

In maven2, the minimum dependency set to make an ADB client work ("ADB" as in the way you created the Java classes from the WSDL) is this:

    <dependency>
            <groupId>org.apache.axis2</groupId>
            <artifactId>axis2-kernel</artifactId>
            <version>1.4.1</version>
    </dependency>
    <dependency>
            <groupId>org.apache.axis2</groupId>
            <artifactId>axis2-adb</artifactId>
            <version>1.4.1</version>
    </dependency>

Hmmm... it seems I can't flag that as the correct answer. Can someone please copy this so I can flag his post?

Answer 3

If your client is running on Java 6, consider using JAX-WS for consuming the WS. JAX-WS uses the JAXB standard for binding and you don't need a single extra jar for the client.

Answer 4

Actually, you only need the axis-abd dependency since the axis2-kernel is a sub-dependency of axis-abd. Therefore you can sum it up with:

<dependency>
    <groupId>org.apache.axis2</groupId>
    <artifactId>axis2-adb</artifactId>
    <version>1.5.1</version>
</dependency>

Answer 5

In Axis2 version 1.5.1 the maven modules appear to have been restructured.

My Groovy scripts (Using ADB binding) have the following dependencies:

@Grapes([
    @Grab(group='org.apache.axis2', module='axis2-kernel', version='1.5.1'),
    @Grab(group='org.apache.axis2', module='axis2-adb', version='1.5.1'),
    @Grab(group='org.apache.axis2', module='axis2-transport-local', version='1.5.1'),
    @Grab(group='org.apache.axis2', module='axis2-transport-http', version='1.5.1'),
])

There's a logic to these. I could use an alternative binding framework when generating my stub or could use an alternative transport protocol to HTTP.

The minimum jars for the client are:

• axis2-kernel-1.5.1.jar, axiom-api-1.2.8.jar, axis2-adb-1.5.1.jar, axiom-impl-1.2.8.jar, activation-1.1.jar wsdl4j-1.6.2.jar, XmlSchema-1.4.3.jar, commons-logging-1.1.1.jar, neethi-2.0.4.jar, axis2-transport-local-1.5.1.jar, axis2-transport-http-1.5.1.jar, commons-httpclient-3.1.jar, mail-1.4.jar httpcore-4.0.jar, commons-codec-1.3.jar

//STAX jars below are not part of Axis2 1.5.1 release and will be needed if your JDK version is less than 6

• stax-1.2.0.jar, stax-api-1.0.1.jar
