Apache CXF example source code file (README.txt)
The Apache CXF README.txt source codeCXF OUTBOUND RESOURCE ADAPTER IBM WEBSPHERE 6.1 SAMPLE ====================================================== This sample demonstrates the new CXF outbound resource adapter. Notice that it does not use the ra.xml file located in <CXF_HOME>/etc directory as does the old outbound sample. Instead, it uses the ra.xml file in the sample's etc directory. You may notice in ra.xml file that the new outbound connect- ion classes have a new package name: org.apache.cxf.jca.outbound. The APIs for new outbound resource adapter use that package name. The src/demo/servlet/HelloWorldServlet.java source file illustrates how to invoke the CXF outbound connector APIs. The RAR deployment descriptor used in this demo is only configured to enable outbound connection for clarity. It is perfectly fine to configure inbound and outbound connector in the same RAR file. The README.txt (this file) provides detailed instructions to run the sample in IBM WebSphere 6.1. However, the cxf.rar and helloworld.war files built by this sample can be deployed to other application servers as well. Please consult application server vendor's documentation for instructions to deploy in other application server environment. In this sample, you will first build a resource adapter RAR file. Next, you will create a web application and compile a WAR file. Upon receiving a request, the web application will make outgoing calls to a CXF web service, gather results, and send responses to the client. The web application is a Servlet that accepts a HTTP request. It then looks up a CXFConnectoryFactory from the application server's JNDI registry. The CXFConnectoryFactory is the entry point to gain access to CXF web service. The application calls the getConnection() method and gets back a CXFConnection. With a CXFConnection, the application can get the web service client by calling the getService() method. The application must close the CXFConnection but the it can continue to use the web service client after the connection has been closed. The sole parameter to CXFConnectoryFactory.getConnection() method is CXFConnectionSpec. The following fields of CXFConnectionSpec are required: serviceName - the QName of the service endpointName - the QName of the endpoint (port name) wsdlURL - the URL of the WSDL serviceClass - the service interface class The following fields of CXFConnectionSpec are optional: busConfigURL - the URL of the CXF bus configuration. If this is provided, it overrides the busConfigURL defined (if any) in the CXFConnectionFactory custom property. (see the next paragraph) address - the transport address The CXF bus configuration can be configured in CXF resource adapter factory's custom property (busConfigURL). More than one factory can be created for each resource adapter. Each factory has a JNDI name and can have different custom property values. The application can choose to (JNDI) lookup the factory (by different JNDI name) it needs and picks up the factory's custom property values. If busConfigURL in the CXFConnectionSpec is specified during the getConnection() call, the value in the CXFConnectionSpec takes precedence over the property value of the connection factory custom property. If no busConfigURL value is set in neither CXFConnectionSpec nor connection factory, default bus will be created. Prerequisite ------------ For IBM WebSphere 6.1, you need to copy <CXF_HOME>/lib/wsdl4j-1.6.2.jar to <WAS_HOME>/AppServer/java/jre/lib/endorsed. If the "endorsed" directory does not exist, create a new one. You need to restart the WebSphere 6.1 server. If your environment already includes cxf-manifest.jar on the CLASSPATH, and the JDK and ant bin directories on the PATH it is not necessary to set the environment as described in the samples directory README. If your environment is not properly configured, or if you are planning on using wsdl2java, javac, and java to build and run the samples, you must set the environment. Building and running the sample using Ant ----------------------------------------- From the base directory of this sample (i.e., where this README file is located), the Ant build.xml file can be used to build and run the sample. Build the common Servlet base jar --------------------------------- (Unix) % cd ../common % ant % cd ../outbound.was (Windows) > cd ..\common > ant > cd ..\outbound.was Build CXF J2C RAR file ---------------------- (Unix) % ant generate.rar (Windows) > ant generate.rar The result RAR file is located in build/classes/lib/cxf.rar Launch the application server ----------------------------- The sample requires an application server (IBM WebSphere 6.1). Make sure you have a running instance of an application server. Enable Tracing CXF messages (Optional) -------------------------------------- To see the full effect of this sample, you will need to enable trace log in your application server. Please consult your vendor documentation on setting tracing and log level. Here are basic instructions to deploy the MDB in WebSphere 6.1. 1. Logon to WebSphere Integrated Solution Console. The default address is: http://<hostname>:9060/ibm/console/login.do 2. Navigate to tree menu: Servers -> Application Servers 3. On the Application servers page, click of the target server (e.g. server1). We will refer the target server as "server1" thereafter. Please subsitute for a suitable server name in your environment. 4. On the next page (Application servers -> server1 in the Configuration tab) and under Troubleshooting, click on Logging and Tracing. 5. On the Logging and Tracking page, click on Change Log Detail Levels. 6. On the next page, click on the Runtime tab. 7. On the next page, check the "Save runtime changes to configuration as well" box. Enter the following in the textbox and then click OK. *=info: org.apache.cxf.*=finest The trace log is located in: <WebSphere install>/AppServer/profiles/AppSrv01/logs/server/trace.log. Please remember to remove the "org.apache.cxf.*=finest" entry in a production environment. Deploy the CXF JCA Connector ----------------------------- The CXF JCA Connector must be deployed to the application server before running the sample. The JCA Connector used in this sample has a unique deployment descriptor (ra.xml) to demonstrate the direct invocation of service implementation resides in the Message Driven Bean. Therefore, the JCA Connector in this sample cannot be used by other JCA samples. Please make sure there is no other CXF JCA Connector deployed into the application server. Please consult your vendor documentation on Resource Adapter deployment. Here are basic instructions to deploy the CXF JCA connector in WebSphere 6.1. 1. Logon to WebSphere Integrated Solution Console. The default address is: http://<hostname>:9060/ibm/console/login.do 2. Navigate to tree menu: Resources -> Resource adapters -> Resource adapters 3. On the Resource adapters page, click the "Install RAR" button. 4. On the Install RAR File page, select the "Local path" radio button if the browser that you are running is on the same machine as the WebSphere server. Otherwise, select the "Server path" radio button. Specify or browse to the path build/lib/cxf.rar file of this sample. Then, click the "Next" button. 5. On the next page, click the "OK" button to install the Resource Adapter. 6. On the next page, click the "CXF JCA Connector" link to edit the Resource Adatper. 7. On the "Configuration" page, click the "J2C connection factories" link. 8. On the next page, click the "New" button to create a new connection factory. 9. On the next page, enter "CXFConnectionFactory" in the Name textbox and click the "OK" button. Notice that the JNDI name is optional. If it is omitted, a JNDI name is created for you as eis/<ConnectionFactory> where Other Apache CXF examples (source code examples)Here is a short list of links related to this Apache CXF README.txt source code file: |
