Take a look there +first. + +If you just want to run it to see what happens open a command prompt, first +navigate to the calculator-corba-service sample 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 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-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 wired +connections with CORBA bindings. Instead of local add, subtract, multiply and +divide components, a CORBA service implementation now provides the +add, subtract, multiply and divide interfaces and is hosted as an CORBA object. +References specified in the .composite file include a CORBA binding which targets +this CORBA object. The name service which is used in CORBA communication is +provided in the test case class - CalculatorCORBAReferenceTestCase.java. + +This sample adds a number of classes to the basic calculator sample: + +calculator-corba-reference/ + src/ + main/ + java/ + calculator/ + CalculatorService.java - as calculator sample + AddService.java - as calculator sample + SubtractService.java - as calculator sample + MultiplyService.java - as calculator sample + DivideService.java - as calculator sample + CalculatorClient.java - as calculator sample + CalculatorServiceImpl.java - calls the CORBA service + that provides the target for the + CORBA bindings in the composite + resources/ + CalculatorCORBAReference.composite - the SCA assembly for this sample + test/ + java/ + calculator/ + CalculatorCORBAReferenceTestCase.java - JUnit test case + CalculatorCORBAServant.java - CORBA service implementation + idl/ - contains files generated + from the IDL file. Files are + used to create a CORBA object which + will be consumed by SCA references. + _CalculatorCORBAServiceImplBase.java + CalculatorCORBAService.java + CalculatorCORBAServiceOperations.java + resources/ + CalculatorCORBA.idl - IDL description for CORBA object + pom.xml - the Maven build file + +Note. 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. + +The calculator-corba-service sample provides a CORBA server that acts as a target +for the SCA CORBA binding. 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 starts the SCA runtime +and calls each of the calculator operations. In doing this the CORBA binding +makes calls out to the CORBA server you started in the previous step. 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-reference +mvn + +You should see the following output from the test phase. + +------------------------------------------------------- + T E S T S +------------------------------------------------------- +Running calculator.CalculatorCORBAReferenceTestCase +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 5.308 sec + +Results : + +Tests run: 1, Failures: 0, Errors: 0, Skipped: 0 + +This shows that the Junit test cases have run successfully. |
