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.

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 Structure
The 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 project. 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.
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.

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 |
...
Run "mvn" under <local tuscany dir>/java directory to install POM files from the root project to the local repository |
...
Commands: |
...
cd <local tuscany dir>/java/das |
...
mvn |
...
Notes: |
...
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 time out. Set up the firewall to permit the action without prompting. |
...
Building Javadoc for DAS |
...
In 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 available at <local tuscany dir>/java/das/rdb/target/apidocs/index.html. |
...
Dependency Jars |
...
The 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 |
...
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'
...

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 application
Below 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 regressions.
