Is there a web service for finding longitude and latitude coordinates from postal codes and zip codes?

Java to WSDL nillable?

Tue, 02 Feb 2010 20:48:37 -0700

baddog posted a new message on the WEB-Services / SOAP forum.

When I generate my wsdl from Java code all of the attributes are set to nillable="true".

I update the wsdl to have nillable="false" for the attributes that must be populated but when the WAR file get's deployed the wsdl sets everything back to nillable="true".

Is there a way to force the wsdl to be unchanged or to create it with the attributes set to nillable=false?

BTW, im using JAX-RPC, AXIS in Tomcat environment.

Any help would be appreciated.

Using Google Web Services API in Java

Thu, 01 Oct 2009 16:42:58 -0700

codebeach submitted a new article.

Google uses SOAP and WSDL standards to allow access from most programming languages. In addition to the SOAP access, Google has created a set of Java wrapper classes that encapsulates access to the Google Web APIs. This tutorial discusses the Java classes and the functionality of the Google web services.

Hi,

I need more information for this.
What web service is it? asmx? or is it a WCF web service?
Can you brows the WSDL in your browser?

: Hello everyone,
:
:
: When we call a remote web services in an asynchronous way, we could
: return the invocation immediately and later we could either call
: Endxxx or our suppied callback will be invoked when the asynchronous
: call result is ready.
:
: My question is, how will the result be delivered to client?
:
: - Does the proxy on client side opens a port and listen to the
: return SOAP message containing the result?
:
: - Does the client use keep alive technique and keeps the Http
: connection open/live from the beginning (when we call BeginXXX to
: invoke the web services) to the end (when the result is ready) -- if
: implemented in this way, there is no need for the client to open a
: port to listen?
:
: - Or implemented in some other ways?
:
:
: thanks in advance,
: George
:

When you call a web service asynchronously the TCP socket remains open until the request is completed. It is asynchronous because the socket waits in a background thread for the response while the rest of your program continues as normal. Once the response is received the background thread calls the callback method.

There is no reason for you to open additional ports or look for another TCP connection.
