Using java comm api

This is a sample java program that reads call information from the EPBX port and dumps it inot an excel sheet.

Basic Security - securing a web service

Ok once you have deployed a web service how do you make it secure.
Put the following snippet in the web.xml file

"
BASIC
Greeting Service


GreetingRole



Greeting Web Service
*


GreetingRole


NONE

"

just before the end tag ""

And in the orion-web.xml file, put the following xml snippet:





Now you are all set. Just deploy the web service again and you would be prompted to provide a user id and password.



As for the java client accessing the wsdl :
In the auto generated constructor, assuming u r using jdeveloper to create and deploy your web services: just provide the properties to the http connection.

Properties props = new Properties();
props.put(OracleSOAPHTTPConnection.AUTH_TYPE, "basic");
props.put(OracleSOAPHTTPConnection.USERNAME, "admin");
props.put(OracleSOAPHTTPConnection.PASSWORD, "welcome");
m_httpConnection.setProperties(props);

OC4J basics

Un deploying web services on OC4J can be a simple command:
java -jar C:\oc4j\j2ee\home\admin.jar ormi://localhost admin welcome
-undeploy

Deployed web services are copied as ear files in the j2ee/home/applications directory and expanded in applications-deployment as any other app server. (META-INF is scrapped from the directory though in deployments directory)
