[MOBY-l] registering an axis web service

[mwilkinson]

It should not be that base64 is *required* by moby.  It is just an option. 

If the code is such that it is now required please say so, because that was not the intention!

For the simplest possible service that I have got to work.., the clode 
for the class is:

public class AxisEcho {
//    echo the request as a byte array - this will result in axis using 
the base64 encoding type required by moby
    public static byte[] echoByteArray(String xml_input) {
          byte[] input_byte = xml_input.getBytes();
          return input_byte;
    }
}

Compile this and put the class file in the axis/WEB-INF/classes 
directory.  Then deploy it by writing a .wsdd file like this

<deployment xmlns="http://xml.apache.org/axis/wsdd/" 
xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
 <service name="AxisEcho" provider="java:RPC" style="rpc" use="encoded">
  <parameter name="className" value="AxisEcho"/>
  <parameter name="allowedMethods" value="echoByteArray"/>
 </service>
</deployment>

and deploy
java org.apache.axis.client.AdminClient my_deploy.wsdd

next restart tomcat.

next register the service.  I've just been using the perl code to do 
this although I know you can do it with Martin's java command line 
client as well.

Here is the relevant code:
sub register_service {
#$C is the moby-central instance
  my $C = shift;
  my $reg = $C->registerService(
    serviceName  => $sname,
    authURI      => $authURI,
    contactEmail => $email,
    description  => "Another axis service for testing",
    URL          => $url,
    input        => [ ['', ["Object" => []]], ],
    output       => [ ['', ["Object" => []]], ],
    category     => "moby",
    serviceType  => "Retrieval",
);
  die "Bad return value from registerService" unless $reg;
  if ($reg->success == 1){
    print "Registration successful\n\n"; 
}
  else {
    print "Registration failed: ", $reg->message, "\n";
  }
}

Thats the idea.  Sorry for leaving an unreachable URL up there - I guess 
maybe that helped push Mark to put up the test central :)

 I was actually using the wrong name..  You can register anything, there 
is no error-checking for bad urls or method names at the time of 
registration.  So, if you put up an incorrect name you can see it, but 
will get a service returned no response message when you try to access it.

This is what I mean by generated locally. If you check the wsdl coming 
back from requests to moby central you will see a much stripped down 
version of the wsdl supplied by axis.

One of my goals for the next few weeks or so is to produce a complete 
working example of an axis moby service that can be deployed in tomcat 
immediately as a war file.  Hopefully that will help get other newbie 
java developers such as myself who are also new to web services and moby 
up and running faster.  

I still have not convinced the sysadmin to open my tomcat port so can't 
share my services just yet :(

Hope that helps a bit, see also the mail from Viji.
