RE: problem integrating the client in another web application: AxisServlet threw exception

[Srinadh Karumuri]

Does any one have a sample code for calling an Axis Web service from a JSP page?

Interesting thing is:

Same code when I tried on Tomcat 3 gives me the following exception:
Internal Servlet Error:

java.lang.IllegalStateException: Response has already been
committed
        at
java.lang.Throwable.fillInStackTrace(Native Method)
        at
java.lang.Throwable.fillInStackTrace(Compiled Code)
        at
java.lang.Throwable.(Compiled Code)
        at
java.lang.Exception.(Compiled Code)
        at
java.lang.RuntimeException.(Compiled Code)
        at
java.lang.IllegalStateException.(Compiled Code)
        at
org.apache.tomcat.core.HttpServletResponseFacade.sendError(Compiled
Code)

Michael,

I checked the HttpClient and understood what you meant. So, it should be working with my web app on the same Tomcat.

As it shows in the RootCouse:

root cause

java.lang.LinkageError: loader constraints violated when linking
javax/xml/soap/SOAPMessage class
        at
org.apache.axis.client.Call.<init>(Call.java:263)
        at
org.apache.axis.client.Service.createCall(Service.java:566)

I started using a simple JSP page but still my Call.init is failing.

Michael,

Thanks for your reply.

I just started calling the web service in the .jsp file.
Here is my client code from .jsp file:

<%
String endpoint =
"http://localhost:8080/bserv/services/EmployeeDataService";

String[] args = {"getEmployeeLateTSDataArray", "22624", "8524"};
String method = args[0];
String arg1 = args[1];;
String arg2 = args[2];;
Service service = new Service();
Call call = null;
QName qname = null;
Class cls = null;

qname = new QName("EmployeeLateTSArray", "EmployeeLateTSBean");
TypeMappingRegistry tmr = service.getTypeMappingRegistry();
TypeMapping tmlts = tmr.createTypeMapping();
try {
  tmlts.register(
    Class.forName("com.bbn.ws.EmployeeLateTSBean"),
    qname,
    new org.apache.axis.encoding.ser.BeanSerializerFactory(EmployeeLateTSBean.class,qname),
    new org.apache.axis.encoding.ser.BeanDeserializerFactory(EmployeeLateTSBean.class,qname));
  } catch (ClassNotFoundException e1) {
    e1.printStackTrace();
  }
tmr.register("http://schemas.xmlsoap.org/soap/encoding/", tmlts);

qname = new QName("EmployeeLateTSArray", "EmployeeLateTSBeanArray");
call = (Call) service.createCall();
call.setReturnType (qname);
try {
  call.setTargetEndpointAddress(new java.net.URL(endpoint));
} catch (MalformedURLException e2) {
  e2.printStackTrace();
}
call.setOperationName(method);
call.addParameter("admnum", XMLType.XSD_INTEGER, ParameterMode.IN);
call.addParameter("mgrnum", XMLType.XSD_INTEGER, ParameterMode.IN);
call.setReturnType(qname);
System.out.println("Called method: " + method + "(" + arg1 + "," + arg2 + ")");
EmployeeLateTSBean e[] = (EmployeeLateTSBean[])call.invoke(new Object[] { new Integer(arg1), new Integer(arg2) });
%>
<%= e[0].toString(); %>

I will look into using HttpClient as you suggested.

Thanks again,
Sri

Sri,

Its hard to tell what you are doing because we don't see any of the
source, but I can tell you that I use commons HttpClient to access one
servlet from another servlet all day long with no problems so you can at
least know that should work.
