DAS ProjectsThis document proves a high-level overview of the Java DAS (Data Access Services) provides information on DAS Java subproject of the Apache Tuscany incubator project. DAS Java Getting Started To get started with Java DAS, follow the downloads link and pick up either a binary or source distribution. If you are working from a source distribution, you can follow the general instructions for building the whole of the Tuscany java projects, or you can follow the intructions within the DAS Java overview to build and explore just DAS java. General DAS DocumentationTitle Description DAS White Paper: The Data Access Service How to access relational data in terms of Service Data Objects JDJ DAS Article How to access relational data in terms of Service Data Objects DAS Java Overview Currently, the project's code base includes an implementation of a DAS RDB (relational database) with following key features : DAS Java Project StructureThe DAS RDB project is divided into three parts: das.rdb contains the DAS interfaces and the RDB (Relational Database) runtime implementation. samples.das provides sample applications based on DAS. distribution.das provides DAS binaries distribution with required dependencies. distribution.das-samples provides DAS samples distribution as a ready-to-deploy war file.

Build Environment Setup Tuscany Build Environment Setup DAS is a subproject of the Tuscany Java project subtree. If you check out and build the whole Tuscany Java project, you will have also built the DAS subproject. If you want to work with the DAS project, without the rest of Tuscany, skip to the next section. To build the whole Tuscany project follow these instructions. DAS Java Build Environment Setup If you want to work with the DAS project alone, without the rest of Tuscany, proceed with the following steps. Show how this can be done
Build DAS subproject Set up your environment using the instructions for building the whole of Tuscany, but only download and install Java 5, Maven and Svn Make sure 'mvn' and 'svn' commands are in your PATH environment variable. Check out the DAS open source projects from Apache. Commands: md <local tuscany dir> cd <local tuscany dir> svn co https://svn.apache.org/repos/asf/incubator/tuscany/java Image Removed Run "mvn" under <local tuscany dir>/java directory to install POM files from the root project to the local repositoryCommands: cd <local tuscany dir>/java/das mvnNotes: If the mvn command completed successfully, you will see BUILD SUCCESSFUL in the output and tuscany-das-rdb-1.0-SNAPSHOP.jar is created under <local tuscany dir>/java/das/rdb/target directory. External resources are at times unavailable. It may be necessary to run "mvn" again at a later time.If you are taking time to reply to firewall prompts, this can cause some requests to Use of Firewall can cause time out. Set up the firewall to permit the action without prompting.
Building Javadoc for DASIn order to build DAS Javadocs, you will need to build the a specific maven profile called "javadoc"Commands: cd <local tuscany dir>/java/das mvn -P javadoc Note: Javadoc will be become available at <local tuscany dir>/java/das/rdb/target/apidocs/index.html. Dependency Jars for DAS.RDBThe DAS.RDB project has a dependency on SDO and requires the following SDO runtime jars to build sdo-api-r2.0.1-1.0-SNAPSHOT.jar - SDO 2.0 Interfaces tuscany-sdo-impl-1.0-SNAPSHOT.jar - SDO 2.0 implementation The SDO.IMPL project have dependencies on the following EMF (Eclipse Modeling Framework - www.eclipse.org/emf) runtime jars to build: common-2.2.1.jar - some common framework utility and base classes ecore-2.2.1.jar - the EMF core runtime implementation classes (the Ecore metamodel) ecore-change-2.2.1.jar - the EMF change recorder and framework ecore-xmi-2.2.1.jar - EMF's default XML (and XMI) serializer and loader xsd-2.2.1.jar - the XML Schema model log4j-1.2.12.jar - log4j logging framework Running DAS Samples DAS provide sample a CompanyWeb scenario where it exposes some of the DAS Features integrated in a J2EE webapp. Follow the steps below to be able to run the samples in a J2EE webserver (in our case Apache Tomcat) From the source repository checkout DAS Sample from SVN repository: md 'local tuscany dir' cd 'local tuscany dir' svn co https://svn.apache.org/repos/asf/incubator/tuscany/java/das Image Removed das use maven to build the CompanyWeb war file: cd das\samples mvn use maven to deploy the CompanyWeb war file to Tomcat mvn tomcat:deploy There are also some sample applications that use a mix of SCA, SDO and DAS. See "Running the Samples" on the Java project page for details. Please check to make sure this is correct From a DAS Sample distribution (starting with M2): Download a das-sample distribution from http://incubator.apache.org/tuscany/downloads.html Image Removed Extract the companyweb war file Follow and follow regular deployment procedures to deploy the war file Running Tuscany DAS Unit Tests DAS is currently providing two sets of unit tests JUnit tests for the core DAS code HTMLUnit tests integrated with Tomcat for DAS CompanyWeb sample applicationBelow we are going to describe how you can exercise these two sets of tests, and we recommend you running them after contributing code/patches for DAS to validate that your new changes are not introducing any regressionsPlease run unit tests as a good practice before submitting your contribution.

Please note that distribution.das-samples provides DAS samples distribution as a ready-to-deploy war file. Following diagram shows the high level class diagram for RDB DAS. Should the following be moved to architecture guide for RDB DAS? Image Added
