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

Don,

Thanks for the sample code. I am stranger to NetBeans so... :(

BTW, I tried my client code in the Servlet(.java) and it's working. I will try forwarding from .java to .jsp. Hopefully it will work on time for my deadline next week.
:)

I've been working on integrating Axis with Netbeans and I just finished the trivial case of using a JSP to consume a WebService.

The import references the package play which was created by wsdl2java and contains the two classes referenced in the scriptlet.

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:

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

org.apache.axis.client.Call.<init>(Call.java:263)

(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.

It used to be that machines automated work, giving us more time to do other things. But now machines automate the production of attention-consuming information, which takes our time. For example, if one person sends the same e-mail message to 10 people, then 10 people have to respond.
