Hi John,
WO web services are based on a Axis implementation that went EOL in
2006. While it was state of the art at the time, I think you'll have
better luck using Java 6's built in JAX-WS stuff instead.
In particular, if you are consuming web services, I found WO web
services to be significantly lacking. It doesn't do much for you with
complex objects modeled in XSD schemas. It can't even correctly parse
a WSDL with XSD imports.
If you are vending a WS, it might work okay, but if I remember
correctly, the preferred WOWS way to do it is with RPC style. Wrapped
document literal style is probably a better choice in most cases...

Another gotcha occurs when you are using D2W. WOWS uses an
incompatible rule model, and the _WSRuleUtilities class will inject it
in its static initializer block... borking your app with a random
crash because ERD2W will correct that automatically but the task and
entity will be null after the correction resulting in
pageForConfigurationNamed() throwing an exception. The WSAssistant is
also completely useless under 5.4 because of the incompatible rule
model too, just in case you might have thought the D2WS stuff looked
cool.

if you Main.class.getMethod("yourMethod").setAccessible(true)
it will probably work

Ok, so it's use in WOWSDDRegistrar.getDeclaredMethodsForClass is
incorrect then, and that's why I can't create a Document style web
service. I love WO 5.4! I'll file a radar.
Thanks,
John

I don't think that means what you think it does ... isAccessible
only returns true if you setAccessible, which tells the VM to skip
VM security checks when you call the method.
You might want Modifier.isPublic(method.getModifiers()) ?

Does anyone know why this code doesn't print anything?
import java.lang.reflect.Method;
public class Main {
public static void main(String[] args) {
for (Method method : Main.class.getDeclaredMethods()) {
if (method.isAccessible()) {
System.out.println(method.getName());
}
}
}
}
I would expect it to print "main" since there is one public method
named "main" in class Main. Isn't that what isAccessible does?
