Optimized soap content
I am attempting to create some web services for existing legacy applications. These applications *CAN* take hundreds of parameters but usually any given invocation will only use a few. My initial approach was to create a java class, called InputParms, that have all of the parameters defined as private with public getter/setters. This way when the client side, via its UI or other appropriate mechanism could set the few parameters needed for this particular service and then invoke the web-service with the InputParms class as one of the services parameters. The service side of the code would then format the data appropriately for the legacy service. However when the InputParms class is serialized into the soap body it becomes very large. I am looking for a technique that is "content" driven so that only those parameters specified are sent. Because of the large number of parameters, I hesitate to surface them in WSDL, because then the WSDL becomes more unwieldy. I am aware that this is not an "AXIS" issue per se, however since the axis is engine is doing the serialization of the classes, I thought that perhaps others have run into this issue. If there are other appropriate forums, pointers to them would be appreciated. Thank you Brad Taylor
RE: Axis fault....where to begin...resolved
I though I would post this out of completeness, just in case anyone else
ever has a similar problem, perhaps my bread crumbs will help.
The bottom line, is that my build environment compiled the java classes
as 1.5, whereas my deployment environment was running java version 1.4.
I got no indication of this until I started paring down the wsdd file,
by incrementally removing first the array-mapping, then the
type-mapping. It then deployed, but still no indications. Then when I
tried to do a list services from the axis web page where it says, and
now some services, it came back with nothing. Then when I looked in
stdout for the tomcat server in my deployment site I saw the following
- Servlet.service() for servlet AxisServlet threw exception
java.lang.UnsupportedClassVersionError:
com/ca/zos/jobs/server/ExecutingJobsSoapBindingSkeleton (Unsupported
major.minor version 49.
0)
I knew from some earlier pain, that this meant I had to provide the
target=1.4 on my javac when I compiled my classes on my development
environment (I had switched to Ant to build the deployment, instead of
just copying the classes from my eclipse environment).

[newbie howto] Create client under axis/apache/tomcat
I have been able to get my service deployed on my "server"
tomcat server and can get results when I run a native application, i.e. an
eclipse Run main, where I specify the appropriate classpaths on the run
statement.
I am looking for the "proper" way to integrate it into my
"client" tomcat server, which is a different machine than my "server" tomcat
server. I am trying put together a JSP that will call my axis
client. My axis service serves an array of classes(objects), where each
class/object consists of 3 simple strings. I am not sure where to put
what. That is on my "client" tomcat server where (what directories) do I
put a jsp that can call a flavor of the "test
client" (clientGetMyNames...not shown). I can probably kluge things
up by putting everything in the class path, but that feels
wrong.
Any clues or help would be greatly
appreciated.
Sample JSP page
<% MyNames[] mn;
mn =
clientGetMyNames("test");
int l = mn.length();
for (int i = 0;i mn.length(); i++)
{ out.println(mn[i].firstName+"
"+mn[i].lastName);
} %>
Details:
the service:
public class MyTestSoapBindingImpl implements
my.test.package.MyTest { my.test.package.MyNames[]
getMyNames(java.lang.String in0) throws java.rmi.RemoteException
{
MyNames[] mn = new
MyNames[5];
code to fill in the mn array
Return mn;
}
}
package my.test.package;
public
class MyNames {
String firstName;
String lastName;
String middleName;
}
The
test client:
public
static void main (String[] args) throws Exception
{ try
{ MyTest binding = new
MyTestServiceLocator().getMyNames();
MyNames[] value =
null; value =
binding.getMyNames("*");
if (value ==
null)
System.out.println("null
results"); else
{
System.out.println("length:
"+value.length);
for (int i = 0;i < value.length;i++)
{
MyNames mn =
value[i];
if (mn != null)
{
System.out.println("Struct["+i+"]:= first:
"+mn.firstName+ ",
last:"+mn.lastName+
",
mid:"+mn.middleName);
}
else
{
System.out.println("String["+i+"]:=
*novalue*");
}
}
} }
catch (java.rmi.RemoteException re)
{
System.out.println("error"+re.toString());
} }
Thank
you

newbie question on deployment
I have been struggling with using java2wsdl, wsdl2java, admin deploy.wsdd as described in the users guide to get a simple test web service deployed and keep running into a wall. I have eclipse, running tomcat under windows. I have tomcat installed in c:\tomcat and axis installed in c:\axis\axis-1_4. I have used axis\axis-1_4\samples\userguide\example6 as a seed for my test. I successfully am able to deploy example6 but not my new test, bradexample. I can run java2wsdl, followed by wsdl2java, followed by the admin client. However I never see the generated java source get compiled into .class files. When I attempt to use the web browser to "list" deployed java services, it complains that it can not find the class files. I did not see anything in the doc about compiling the java source generated from wsdl2java. When I try to do it manually I get a java compiler error about not being able find symbol. I believe the example6 deploys correctly because the class files are in the tomcat/.../webapps/axisdirectory. So I guess the question where the .class files come from that correspond to the generated .java files from the wsdl2java process. Do I need to manually compile, then copy? Or is this supposed to be automatic? Brad Taylor Senior Software Engineer Workload Automation 713 625 9490 (ext 11940)
