We will create the needed classes to generate a Web Service client from its WSDL.
We will base in the HelloWorld project, and here will add the security. In this project we response with a Hello for the name which sent as argument through the Web Service.
We want to intercept the WS input and output. In order to:
Here we are going to do a input/output WS example log.
We annotate the WS with Handler Chain descriptor:
@WebService @HandlerChain(file="src/META-INF/handlerChain.xml") public class Hello { @WebMethod public String sayHello(String name) { return "Hello, "+name+"."; } }
It will have the following contents:
<?xml version="1.0" encoding="UTF-8"?> <handler-chains xmlns="http://java.sun.com/xml/ns/javaee"> <handler-chain> <handler> <handler-class>lebrijo.handlers.WSHandler</handler-class> </handler> </handler-chain> </handler-chains>
WSHandler class will implements the SOAPHandler interface:
public class WSHandler implements SOAPHandler<SOAPMessageContext> { public Set<QName> getHeaders() { return null; } public boolean handleFault(SOAPMessageContext context) { logToSystemOut(context); return true; } public boolean handleMessage(SOAPMessageContext context) { logToSystemOut(context); return true; } private void logToSystemOut(SOAPMessageContext smc) { Boolean outboundProperty = (Boolean) smc.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY); if (outboundProperty.booleanValue()) { System.out.println("Outgoing message:"); } else { System.out.println("Incoming message:"); } SOAPMessage message = smc.getMessage(); try { message.writeTo(System.out); } catch (Exception e) { System.out.println("Exception in handler: " + e); } } public void close(MessageContext context) { // TODO Auto-generated method stub }
In this post we are going to see how to secure a Web Service with basic HTTP Auth, in weblogic. We will base in a previous project where we created a very basic WS: Hello World.
In the Security Realm > MyRealm we have to create:
In the Weblogic console as we see on the picture:
In web.xml we have to add the security confs needed (path, basic type,….):
<!-- SECURITY --> <security-constraint> <display-name>Regla01</display-name> <web-resource-collection> <web-resource-name>WSPOST</web-resource-name> <description> <url-pattern>/*</url-pattern> <http-method>POST</http-method> </description> <auth-constraint> <description> <role-name>TutorialUser</role-name> </description> </auth-constraint> <session-config> <session-timeout>5</session-timeout> </session-config> <login-config> <auth-method>BASIC</auth-method> <realm-name>myrealm</realm-name> </login-config> <security-role> <description> <role-name>TutorialUser</role-name> </description> </security-role> </web-resource-collection> </security-constraint>
In weblogic.xml map the application role with server role (it is mandatory):
<wls:security-role-assignment> <wls:role-name>TutorialUser</wls:role-name> <wls:principal-name>TutorialUser</wls:principal-name> </wls:security-role-assignment>
We can test with SoapUI creating a new WS project, with WSDL address (http://localhost:7001/wsc/HelloService?WSDL) and previous Weblogic credentials created:
Today we will create a SOAP Web Service, based on LebrijoSchool project which we were making in early weeks over Oracle-Weblogic Architechture.
First of all is to add the Web Services facet. Right button > Properties … :
After, we will create the class from a Spring Service class. Right button > New > WebLogic Web Service for Spring Beans:
Choose the Service, and the methods that we want to publish as Web Service.
Finally put it in the logical package: lebrijo.school.webservices. And name it as “SchoolCertificatesWS”.
This is the code:
@Autowired @Qualifier("RegistryService") private IRegistryService springServ; @WebMethod public Registry findRegistryById(java.lang.String id) throws Exception { return springServ.findRegistryById( id ); }
We have a Weblogic client to test the WS, we can acces thru the URL http://localhost:7001/wls_utc/.
Today we are going to see ho to create a WS which says Hello over Weblogic, with its IDE Eclipse OEPE.
We will create a New project > Web Service Project:
We created teh following class:
package services;import javax.jws.*; @WebService public class Hello { @WebMethod public String sayHello(String name) { return "Hello, "+name+"."; } }
With these annotations we can serve the WS, and with right button on the classes and Run as > Run on Server. It launches the test WS application in the navigator:
To access to WSDL: http://localhost:7001/wsc/HelloService?WSDL
To test every WSDL published: http://localhost:7001/wls_utc/begin.do
