PHP SoapClient hangs while waiting for Java javax.xml.ws.Endpoint to return WSDL
In Java, I have a simple Web Service, by using the @WebService and @SOAPBinding annotations and a class with the method I want to export.
In PHP, I have a simple SOAPClient, that connects to the aforementioned Web Service and supposed to call a method from it.
The PHP scripts terminated with a timeout, while trying to retrieve the WSDL. I see the HTTP connection still remains open.
After a while, in the background, the cached WSDL is created in the temporary directory.
Once that happens, the PHP scripts works and calls the SOAP method successfully!
Is it possible that the Java Web Service doesn't close the HTTP connection for the WSDL, and the PHP script keeps waiting? Any ideas where can the problem be, and how to fix it?
* Important Note *
Same PHP does work when trying with another web service, e.g. http://www.w3schools.com/w
Same Java WS does work when trying with another client, e.g. http://www.soapui.org/

romi_k, Please don't misinterpret this answer - it is not a direct answer but just advice about web services and for me it is hard-won knowledge. I hate SOAP for exactly the kind of problem you are experiencing here.
Instead I like to use RESTful web services. In a REST interface, the calling program has no knowledge of the structure inside the web service, and needs none. All of the calls are "atomic" - there is no programmatic interdependency or sequence to the calls. The calling program places all of its arguments in the URL "get" string and reads its results via file_get_contents().
The elegant simplicity of this protocol may include authentication via an API key. Some good examples can be found on Yahoo. Check their page and the linked pages here:

Hope that can help simplify things for you, ~Ray
