Question

I seem to be having an issue with Java and NetBeans when it comes to writing web services.
I have searched for a couple of days with no luck, finding people with the same issue as me with zero replies.

I have created a web service which returns a complex type (LoginReply), and that complex type contains an array of another complex type (AppInfo)

However when I generate the WSDL from this, the complex type definition in the XSD is blank, and manually adding the information still makes the web service return null even when data is successfully passed to the web service.

<xs:complexType name="appInfo">
<xs:sequence/>
</xs:complexType>

LoginReply: http://pastebin.com/Umx6ayvi
AppInfo: http://pastebin.com/566WnZ4H

If anyone could point out what I’m doing wrong, or if this is a bug with NetBeans, I’m new to Java so I can’t rule out that I’m simply not understanding something, but I’m close to pulling my hair out here.

EDIT:

Just noticed when i deploy to tomcat via NetBeans I get the following error:

WARNING: duplicate class definition bug occured? Please report this :    uk/co/example/ComplexTypes/LoginReply$JaxbAccessorM_getApplications_setApplications_[Luk_co_example_ComplexTypes_AppInfo;

java.lang.ClassFormatError: Illegal class name "uk/co/example/ComplexTypes/LoginReply$JaxbAccessorM_getApplications_setApplications_[Luk_co_example_ComplexTypes_AppInfo;" in class file uk/co/example/ComplexTypes/LoginReply$JaxbAccessorM_getApplications_setApplications_[Luk_co_example_ComplexTypes_AppInfo;

Notice the random L before co_uk_example. My research suggests this is an old bug that should be fixed, and that no one else has reported this issue in over a year, no sure where to go from here.

Another edit:

Just added a new web method on the service that simply gets a list of appInfo and returns it to the client. This still fails the same way with NetBeans refusing to generate a sequence inside AppInfo.
I’m sure I’m missing something to declare the class, but I have checked it countless times to ensure I’m not missing anything.

This Issue came down to a very simple mistake. The AppInfo class was using non-standard getters and setters.

public void SetAppID(int AppID)
{
    this.AppID = AppID;
}

This is INCORRECT (notice the capital on the Set), it should be:

public void setAppID(int AppID)
{
    this.AppID = AppID;
}

Using a capital is not standard for JavaBeans and as such JAX-WS didn’t know how to generate WSDL for this class. Thanks too shyam from the following link for answering the question
