Forwarding a web service call...
All,
I am using axis to run the same set of web services on several different
servers.
One of the methods is called "getItem". I am not sure if this makes
sense or not, but, here goes.
If I call getItem on one server and the item does not exist in that
database, I want the call to be "forwarded" to the next server in the
chain. I tried creating a proxy class and changing the endpoint and
passing the parameters to the next server, but this does not work...
Here is some sample code:
<pre>
public ItemInfo getItem(CredentialsInfo credentials,String itemId) {
...
"get the item from the current database"
If (theItem == null) {
CETGServicesProxy proxy = new CETGServicesProxy();
proxy.setEndpoint("http://nextserver.com/cetgws/services/CETGServices");
ItemInfo item = proxy.getItem(credentials,itemId);
return item;
}
...
</pre>
Is this possible, or, am I just being mentally challenged?
Thanks for any help...

Good Afternoon Stan--
CLIENT
lets say for the sake of argument your client's packagename is called
package samples.userguide.example2
and the class is called TestClient.java
after compiling the TestClient your TestClient.class should be located in
<BaseFolder>/samples/userguide/example2/TestClient.class
so in my case I have use Axis folder for the BaseFolder
the class is located in
/Axis/samples/userguide/example2/TestClient.class
and the way I invoke the AxisClient is to
cd Axis
java -classpath .;$CLASSPATH samples.userguide.example2.TestClient
the TestClient main method as a reference to setendpoint as here
call.setTargetEndpointAddress( new java.net.URL(endpoint) );
where endpoint is set to
String endpoint = http://localhost:8080/axis/services/MessageWebService
once you invoke the WebService via
call.invoke( params)
the deployed service 'MessageWebService' Server has the ball and will call the associated stub classes (located on TOMCAT axis folder SERVER configuration)
SERVER configuration
from the package point of view the (assume previouslt generated stub) server classes are located in either one of 2 places
1)individual classes can be located in the classes folder as in
$TOMCAT_HOME/webapps/axis/WEB-INF/classes/PACKAGENAME/CLASSNAME
2)the library (jar file) can be located in lib folder as in the example
$TOMCAT_HOME/webapps/axis/WEB-INF/lib/*.jar

Martin,
Thanks for your response, but to be perfectly honest, I didn't understand a single word of that. I guess I am still a newbie..
I am not actually using any of the Axis api for the things I have done thus far, so, digging into the servlet and such are a little beyond me.
Is there not any way I can use a proxy (client) to another system to do what I want? I was thinking I could go through and change package names and such to differentiate the client from the actual (server side) implementation, but, I found this to be fairly difficult as well - not that I mind difficult. I just need to know what actually works.
Thanks again,
Stan

Good Morning Stan--
Far from it ..You're NOT mentally challenged at all..You're asking a valid question which SHOULD be asked!
As forwarding a response is a challenge I found earlier this week.. I countered the error by creating a few mutator methods in MessageContext notably
msgContext.setResponse and msgContext.setRequest to be set from within AxisServlet as soon (as the msgContext object is acquired)
Later in in your <WebService>Manager Stub class when you acquire the msgContext object
you will be able to re-acquire the original response and request objects via MessageContext accessor methods-
BTW When I originally posted this same question I did get a response from dims (Apache committer) as well as Luis (from IEEE)
I hope this helps your efforts-

Re: Axis tutorial. Did anyone buy it?
Posted by José Ferreiro <jo...@gmail.com>.
It is more like a tutorial.
Don't expect buying this book that they will explain in all details how
the libraries work and so on but
it is a good starting develop your first secure web service using
Tomcat, Axis 1.x, WSS4J, keytool and Eclipse.
Hope this helps
Happy Axis.

Hello
ISBN is: 1-4116-7032-9.
I wanted to learn how to set up a secure web service using
signature and encryption and I bought it.
It is a good way to achieve your goal.
Obviously you should not neglect to look always at the javadoc of WSS4J and
Axis 1.X .
You may look at the table of contents here:
http://www.agileskills2.org/DWSAA/FourtyPages.pdf
Hope this helps.
I wish a wonderful day to everybody
and HAPPY AXIS
