I have searched the archives, but have not gotten quite enough of a clue to solve the problem I face. I wish to use Java to get the results from a call to a SOAP server running Perl SOAP::Lite. The function returns a hash ref, encoded as SOAP::Lite encodes. (raw soap call/return below.)
I apologize for the long message, but I have found that God is in the details in this space, and if it is just a simple typo in some routine, the real source is required.
The server is running SOAP::Lite 0.55. It is sending back a hashref, and I have not been able to create the proper WSDL to see it, possibly because of how SOAP::Lite is sending back that hashref. I can handle simple types like ints and strings, but this is not working.
I am using stubs created by wsdl2java, so clearly I need to express this soap-struct in my WSDL, but I do not seem to be able to create the proper type in the WSDL, or at least, it is not being used.
I cannot really change the underlying routines on the server, as they are used for many things, but I can modify the dispatch function called by mod_perl. I have attached it at the end.

The java code:

try{
String endpoint = "http://feature.alodar.com/gbib-soap/";;UserUtilsPort userUtilsPort = new GBIBServiceLocator().getUserUtils(new URL(endpoint));
((UserUtilsStub)userUtilsPort).setTimeout(60000);

((ListUtilsStub)listUtilsPort).setTimeout(60000);
// works great!
int get_id_for_usernameResult=userUtilsPort.get_id_for_username("config_name ", config_name, "username", "admin");

// throws exception
Object get_user_ids_by_nameResult = userUtilsPort.get_user_ids_by_name("config_name", config_name);
printResult("get_user_ids_by_name", get_user_ids_by_nameResult);
} catch (Exception e) {
System.err.println("Error: "+e.toString());
}
}The dispatcher is very simple:
sub handler {
SOAP::Transport::HTTP::Apache -> dispatch_to(
qw(
Alodar::GBIB::ListUtils::get_public_lists
Alodar::GBIB::UserUtils::get_id_for_username
Alodar::GBIB::UserUtils::get_user_ids_by_name
Alodar::GBIB::UserUtils::get_username_for_id
)
) ->handler(@_)I can add more things to this, as long as they can go here.
The exception is:
[java] Result of get_id_for_username was type int, value 1
[java] Result of get_username_for_id was type java.lang.String, value admin
[java] - Exception:
