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 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
This needs to be updated to reflect the new DAS structure which will include LDAP and XQuery
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 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.
Build Environment Setup
...
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
...
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.
[Note: 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 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 become available at <local tuscany dir>/java/das/rdb/target/apidocs/index.html.
Dependency Jars for DAS.RDB
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
...
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)
...
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
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):
...
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
...
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.

DAS RDB Code Structure
Currently, the project's code base includes an implementation of a DAS RDB (relational database) and it is divided into three parts:
1. das.rdb contains the DAS interfaces and the RDB (Relational Database) runtime implementation.
2. samples.das provides sample applications based on DAS.
3. distribution.das provides DAS binaries distribution with required dependencies.
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?
