Milestone 5 is +delivered in a state of partial change over to this new emphasis, and hence +this README reflects that hybrid state. + +There are primarily 3 types of sample; those which focus on pure SCA +concepts, those which demonstrate features of Tuscany and the last group +is of samples which give a flavour of more complete, realistic applications. + +The new structure primarily focusses separating contributions from the way that +contributions are launched. The samples demonstrate the way in which contributions are used by +launchers to execute tuscany SCA applications. + +In this way you can explore the samples by chosing which launcher you wish +to invoke which contribution. In the old style of sample this distinction was not clear; +any given sample contained both launcher and contribution, and the set of samples provided +represented a small subset of the combinations possible by the new approach. + +Within the SCA category of samples, most of the calculator samples, have been +migrated to this new structure as follows. + +SCA Samples + binding-rmi-calculator + contribution-calculator-reference + contribution-calculator-service + binding-sca + contribution-calculator + contribution-binding-ws-calculator + contribution-implementation-java-calculator + calculator-sca-client + launcher-command-line + launcher-embedded-jse + launcher-embedded-osgi + launcher-mvn + +Please visit the 2.x documentation in our website [1] to get a better understanding of SCA +and Tuscany 2.x + +Running the New Style samples +----------------------------- + +To run a new style sample there are 3 basic steps + +1) build the contribution: using either the command "mvn", "ant run" or your usual steps to build a + module in your IDE +2) unit test the contribution: if you used mvn or ant in step 1 then you will already have done this; + if you used an IDE follow your usual steps to run the unit test in the contribution's module +3) launch the contribution: go to one of the launcher* subdirectories of the samples root directory + and follow the instructions there to use a launcher to launch your chosen contribution + +I the case where you want to exercise the sample contribution with a separate client program, such as +an application using the SCA client API then there is a 4th step of starting that client application + +[1] http://tuscany.apache.org/documentation-2x/ + +Running the Old Style Samples +------------------------------ +The Apache Tuscany SCA samples are built as part of the main Maven build and +run, using the provided JUnit test cases, as tests in the Maven build. + +In the binary distribution of Apache Tuscany most samples can also +be run using the provided Ant build.xml files. These show the samples running +from a simple main() method without the need for a JUnit test case. + +In these notes text that appears in angled brackets like this <example> means +that you need to make a choice and provide your own text at that point. + +These simple samples have been created with the intention of illustrating the +usage of the SCA API and annotations and certainly not to levels of SCA component +abstraction. In real life situations you should use SCA to assemble real and +usually bigger components, and when you do that you'll get all the benefits of +SCA, bindings, policies, integration in an SOA environment etc.. + +Sample Layout +------------- +Generally sample directories are organized in the same way based on the default +project template provided by Maven. For example, take a look at the calculator +sample; + +calculator/ + src/ - Holds all of the source files for the sample + main/ - Groups together the files that implement the sample + java/ - Java source files + resources/ - Non java resource files such as composte files + test/ - Groups together files that provide sample tests + java - Java test sources files. Usually JUnit test cases + target/ - Holds the files generated when the sample is built + classes/ - For example, Java class files + test-classes/ - classes from src/test and other test files + +Getting Ready To Build +---------------------- +You will need to install the following software before you start. + +J2SE Development Kit (JDK) 5.0 +Apache Ant 1.7.1 - if you are going to use Ant +Apache Maven 2.0.9 - if you are going to use Maven + +Java and Ant and/or Maven binary directories must be present in your PATH so +that their executable programs are available in your environment. You may +find it useful to use a script to set up your environment, for example; + +For UNIX: + JAVA_HOME=/<installation_directory> + ANT_HOME=/<installation_directory>/apache-ant-1.7.0 + MAVEN_HOME=/<installation_directory>/maven-2.0.6 + export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$MAVEN_HOME/bin:$PATH + +For Windows: + set JAVA_HOME=C:\<installation_directory> + set ANT_HOME=C:\<installation_directory>\apache-ant-1.7.0 + set MAVEN_HOME=C:\<installation_directory>\maven-2.0.6 + set PATH=%JAVA_HOME%\bin;%ANT_HOME%\bin;%MAVEN_HOME%\bin;%PATH% + + +Building And Running The SCA Samples Using Ant +---------------------------------------------- +The build.xml files provided with the Apache Tuscany SCA samples are designed +to work with the binary distribution. They rely on the tuscany-sca-manifest.jar +to describe the class path and this jar is only provided as part of the +binary distribution. + +The binary distribution of SCA also includes precompiled versions of each sample. +If you look in the target directory of each sample you will see this jar file. To +run a sample based on all of the precompiled artifacts all you have to do is: + +cd <sampledir> +ant run + +Check each <sampledir>/README file as some samples require that two progams are +run to get the desired result, for example, the two samples that show how +to build extensions are run from their associated application samples. + +If you want to rebuild a sample, for example, if you have changed it, do the +following: + +cd <sampledir> +ant compile + +Once the sample is built you have the option of running the sample in whatever +way best suits you. Two alternatives are provided in the ant build files. + +The compile target builds the class files and then builds the jar so you can use +the same command as before: + +ant run + +This will use the generated jar to run the samples. The command line version of +this is: + +on Windows + +java -cp ..\..\features\tuscany-sca-manifest.jar;target\<sample jar file> <sample runnable class> + +for example : java -cp ..\..\features\tuscany-sca-manifest.jar;target\sample-calculator.jar calculator.CalculatorClient + +on *nix + +java -cp ../../features/tuscany-sca-manifest.jar:target/<sample jar file> <sample runnable class> + +for example : java -cp ../../features/tuscany-sca-manifest.jar:target/sample-calculator.jar calculator.CalculatorClient + + +You can use the compiled classes directly using + +ant run-classes + +The command line version of this is: + +on Windows + +java -cp ..\..\features\tuscany-sca-manifest.jar;target\classes <sample runnable class> + +for example : java -cp ..\..\features\tuscany-sca-manifest.jar;target\classes calculator.CalculatorClient + +on *nix + +java -cp ../../features/tuscany-sca-manifest.jar:target/classes <sample runnable class> + +for example : java -cp ../../features/tuscany-sca-manifest.jar:target/classes calculator.CalculatorClient + +The class specified on the command of course depends on which sample you want to +run. In the examples we have used we are running the CalculatorClient from the calculator sample. + + +Building And Running The SCA Samples Using Maven +------------------------------------------------ + +The Maven build process will work from both source and binary distributions. +To build and test all of the Apache Tuscany SCA sources, including the samples, +do the following. + +cd sca +mvn + +This will take a little while to complete. Experience with Maven tells us that +sometimes there are problems downloading the dependencies that Apache Tuscany +SCA requires. If Maven reports that it cannot download required dependencies +try running the Maven build again. + +Once you have all of the source built you can build and run each sample +independently if required. + +cd <sampledir> +mvn + +When using Maven the samples are run within JUnit test cases and so you will +sometimes not see any test output. You will always see an indication of test +success or failure. + +Using The Samples In An IDE +--------------------------------------------- +The easiest way to use the samples in an IDE is to use Maven to generate all +of the IDE project files for you automatically. This works best if you +generate IDE projects for all of the Apache Tuscany modules. You can then +include the ones you are interested in working with in you IDE. + +To build IDE project files for all of the modules in Apache Tuscany SCA; + +cd sca + +If you are an Eclipse user do the following + +mvn -Peclipse + +If you are an IDEA user do the following + +mvn idea:idea + +These commands generate project files for each module in Apache Tuscany SCA. +The modules you are interested in can now be included in your IDE, for example, +in Eclipse, if you create a new Java project and use the option to "create a +new project from existing source" you can specify an SCA module directory, +which includes the generated project files, and Eclipse will treat it like any +other Java project. + +Using The Samples In An IDE Without Maven +----------------------------------------- +We don't provide any IDE project files with our distributions so you will have to +import the sample files into your IDE manually. Here's an example of how it can be +done using Eclipse. + +In a new or existing workspace + Create a new java project to represent the sample you want to work on, e.g. + launcher-embedded-jse + Import all of the sample code and resources into this project, e.g. + File, Import and then select tuscany-sca-1.0-incubating\samples\launcher-embedded-jse from the filesystem + Configure the source path to include + src/main/java + src/main/resources + Configure the output folder to be + target + Configure the build path to include the manifest jar tuscany-sca-manifiest.jar provided in + features + For here you have run; + the unit test (loads a sequence of contributions and runs them) + SampleJSELauncher (you'll need to add the name of the contribution to run as a parameter) + build.xml (you'll need to set tuscany.home to point to distribution\all\target\apache-tuscany-sca-all-2.0-SNAPSHOT.dir\tuscany-sca-2.0-SNAPSHOT) + +The details of how to do this for other development environments will +vary but the process will be similar. + + |
