Thanks William and Sashwat for your suggestions. I was able to get webService and client to work using axis2 using their wizards . I actually used axis2-1.1.1 nightly build to get them working.

I have another question about client code generated using webservices toolkit on Excel 2003 if any of you have worked on this before.
I have used http://www.oreilly.com/pub/h/1306
to test the webservice on Excel. When I created the webservice using websphere soap engine on rad 6.0 Excel created structures (VB code) for all my DTOs with that wsdl one of my input objects is mapped to
ex: struct_OpportunityCountRequ with fields
Public nwieId As String
Public oppLibId As Double
Public producerNumber As String
Public mailable As Boolean

but when I created wsdl from axis2 soap engine ( axis2 wizards added as plugin to RAD 6.0) then I could not get the structures for the DTOS of my webservice methods .Instead I have all the DTOS mapped to MSXML2.IXMLDOMNodeList in VB code

Could any one let me the reason for this difference in code generation ?
I would appreciate any suggestions.
Thanks,

Hi All,
I would like to add error specific information for prev posting.Sorry for two mails. The error while invoking the happyAxis.jsp in my previous posting was returning 500 internal error , the response is:
---

The server cannot use the error page specified for your application to handle the Original Exception printed below. Please see the Error Page Exception below for a description of the problem with the specified error page.


Original Exception:
Error Message:
Error Code: 500

Error Stack:
java.lang.NullPointerException

The error page entry is present in web.xml as
<error-page>

and the corresponding jsp is present in axis2-web directory

hi,
I am trying to deploy axis2 webservices in RAD 6.0 using Web Sphere 5.1 test server and I have used the instructions specified at
https://coderanch.com/t/77805/Websphere/Axis-WSAD
to make it to work.I downloaded axis 1.4 first.I could make the axis servlet to work with out adding any axis2 related classes.

Later I downloaded axis2-war distribution from
http://ws.apache.org/axis2/download/1_1/download.cgi
and tried to copy the files
(axis2 libraries, jsps and other folders in WEB-INF like services,conf etc) into the working web application but end up getting the following error while invoking
http://localhost:9080/AxisDemo/axis2-web/HappyAxis.jsp

from my Web Application ( AxisDemo)

The error is :
------------------------------------
[1/1/07 16:08:03:458 EST] 59e9eb9a WebGroup I SRVE0180I: [Apache-Axis] [/AxisDemo] [Servlet.LOG]: /axis2-web/include/httpbase.jsp: init
[1/1/07 16:08:03:478 EST] 59e9eb9a WebGroup E SRVE0026E: [Servlet Error]-[]: java.lang.NullPointerException
at org.apache.jsp._httpbase.jspInit(_httpbase.java:26)
at com.ibm.ws.webcontainer.jsp.runtime.HttpJspBase.init(HttpJspBase.java:59)
---------------------------
i.e; the http base servlet is not instantiated.

Could any body help me locate the problem if any one has already worked with axis2 on Web Sphere 5.1 test server.Pl lemme knwo if this is the right way.
Thanks in advance,

Hi All,
I registered with IBM UDDI test registry with user name and password and tried to connect to it using a servlet with the following code:
----------
javax.naming.InitialContext jndiEnc=new javax.naming.InitialContext();
ConnectionFactory factory= (ConnectionFactory) jndiEnc.lookup("java:comp/env/eis/JAXR");
Connection connection=factory.createConnection();

PasswordAuthentication credential = new PasswordAuthentication(userName, password.toCharArray());
Set credentials = new HashSet();
credentials.add(credential);
connection.setCredentials(credentials);
-------------------
I could get the connection but while setting the credential I got the following error:
--------
com.sun.xml.messaging.saaj.SOAPExceptionImpl: java.security.PrivilegedActionException: com.sun.xml.messaging.saaj.SOAPExceptionImpl: Message send failed
--------
at line "connection.setCredentials(credentials)
-----
I gave the same user-id and password that I gave for UDDI test registry . Can any one guide me.I am not sure whether the attributes I set for the JAXR Resource Adapter are correct. I used the following:
---
AuthMethod: UDDI_GET_AUTHTOKEN
HttpsProxyPort:8181
HttpProxyPort:8080
HttpProxyHost:localhost
HttpsProxyHost:localhost
LifeCycleManagerURL:https://uddi.ibm.com/testregistry/publishapi
QueryManagerURL:http://uddi.ibm.com/testregistry/inquiryapi
---
I would really appreciate if any one could provide some hints,
Thanks in advance

Hi,
I am trying to connect to UDDI registry with the following code
--------
try{
//create a connection factory
ConnectionFactory factory=ConnectionFactory.newInstance();

//configuring the connection factory
Properties prop=new Properties();
prop.setProperty("javax.xml.registry.lifeCycleManagerURL","https://uddi.ibm.com/testregistry/publishapi");
prop.setProperty("javax.xml.registry.queryManagerURL","http://uddi.ibm.com/testregistry/inquiryapi");
prop.setProperty("javax.xml.registry.factoryClass","com.sun.xml.registry.uddi.ConnectionFactoryImpl");
prop.setProperty("javax.xml.registry.security.authenticationMethod","UDDI_GET_AUTHTOKEN");
factory.setProperties(prop);

// now create the connection
Connection connection=factory.createConnection();
.......


-----------------
and I got the following exception

Can any one tell me how to handle this exception? Do I need to set some more properties while creating the connection?

Thanks in advance
