It also demonstrates how a simple +Java CORBA Client application invokes the SCA Application's services +exposed as CORBA objects. + +The README in the samples directory (the directory above this) provides +general instructions about building and running samples. Take a look there +first. + +If you just want to run it to see what happens open a command prompt, navigate +to this sample directory and do: + +ant run + +OR if you don't have ant, on Windows do + +java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-corba-service.jar calculator.CalculatorCORBAServer + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-corba-service.jar calculator.CalculatorCORBAServer + +Now you have the server running you need to open another command prompt, navigate +to the calculator-corba-reference sample directory and do: + +ant run + +OR if you don't have ant, on Windows do + +java -cp ..\..\lib\tuscany-sca-manifest.jar;target\sample-calculator-corba-reference.jar calculator.CalculatorClient + +and on *nix do + +java -cp ../../lib/tuscany-sca-manifest.jar:target/sample-calculator-corba-reference.jar calculator.CalculatorClient + +Sample Overview +--------------- +This sample extends the calculator sample by replacing the local service +binding with a CORBA binding. A Java client can use CORBA client code to +call the service exposed by the SCA application. The name service which is +used in CORBA communication is provided by the Tuscany CORBA hosting module +(maven dependency: tuscany-host-corba-jse-tns) - see the binding.corba reference +on the Apache Tuscany website for details. + +This sample adds a number of classes to the basic calculator sample: + +calculator-corba-service/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - as calculator sample + CalculatorServiceImpl.java + AddService.java - as calculator sample + AddServiceImpl.java + SubtractService.java - as calculator sample + SubtractServiceImpl.java + MultiplyService.java - as calculator sample + MultiplyServiceImpl.java + DivideService.java - as calculator sample + DivideServiceImpl.java + resources/ + CalculatorCORBAServer.composite - the SCA assembly for this sample + test/ + java/ + calculator/ + CalculatorCORBAServerTestCase.java - JUnit test case + idl/ - contains files generated + from the IDL file.

As this test creates and uses local network connections you may need to +configure your firewall, if you are running one, to allow the test to run +successfully. + +Building And Running The Sample Using Ant +----------------------------------------- +With the binary distribution the sample can be built and run using Ant. Two +build files are used to support client and server functions. + +The server starts the SCA runtime and loads the SCA calculator application +which exposes a CORBA service. Start a new console and use the following +commands. + +cd calculator-corba-service +ant compile +ant run + +This will run up the server and display the following. + +run: + [java] Calculator CORBA server started (press enter to shutdown) + +The client is very similar to the calculator sample + +It locates the CORBA service that the SCA runtime is exposing and calls each of +the calculator operations. Start a new console and use the following commands. + +cd calculator-corba-reference +ant compile +ant run + +You should see the following output from the run target. + +run: + [java] 3 + 2=5.0 + [java] 3 - 2=1.0 + [java] 3 * 2=6.0 + [java] 3 / 2=1.5 + +If you now return to the console window running the server and press enter the +server should stop. + +Building And Running The Sample Using Maven +------------------------------------------- +With either the binary or source distributions the sample can be built and run +using Maven as follows. + +cd calculator-corba-service +mvn + +You should see the following output from the test phase. + +------------------------------------------------------- + T E S T S +------------------------------------------------------- +Running calculator.CalculatorCORBAServerTestCase +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 5.819 sec + +Results : + +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 + +This shows that the Junit test cases have run successfully. |
