export stateless session bean as webservice

[reeves]

Hi all !

I want to export my session bean as webservice,
the problem is that I use complex bean as return value.
I was able to generate web-service.xml using xdoclet tag
but I've got "no deserialiser found" when calling my webservice.

Thanks in advance for any help !


here my web-service.xml :

<?xml version="1.0" encoding="UTF-8"?>

<deployment
xmlns="http://xml.apache.org/axis/wsdd/"
targetNamespace="http://net.jboss.org/hello"
xmlns:hello="http://net.jboss.org/hello"
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
<!-- this is an extension to the Axis deployment descriptor which allows to
specify the naming environment for the deployed ws logic -->



















and UserInfo.java
public class UserInfo implements java.io.Serializable
{
private boolean authentified;
private java.lang.String[] userPlugins;

public UserInfo() {
}

public boolean isAuthentified() {
return authentified;
}

public void setAuthentified(boolean authentified) {
this.authentified = authentified;
}

public java.lang.String[] getUserPlugins() {
return userPlugins;
}

public void setUserPlugins(java.lang.String[] userPlugins) {
this.userPlugins = userPlugins;
}

}

UserInfo may be too complex for the standard deserializer to handle. It doesn't look like a standard Bean in that there are not the standard setters and getters. Also, you have a complex get and set element with a String[]. Check the Axis site and the associated WIKI for more information on custom serializers and deserializers. There are also more in-depth discussions in the Axis mailing lists.

That is all I can suggest at this stage.

In your Ant file :

Add : <fileset dir="${java.dir}" includes="**/webservice/*.java" /> to your ejbdoclet task
werservice is the directory which contains all your webservice bean

Add this subtask to ejbdoclet task
<jbossnet prefix="yourPrefix"
destdir="${build.dir}/META-INF/" />

you should have something like :














next write your session bean and your UserInfo bean
in a directory name "webservice"

And that's all ! web-service.xml contains all you want !
Going to write a real tutorial that explain all this process
and post it here.

Just one more thinks, notice that you have to use
String[] instead of java.lang.String[] don't know why .... :-(
