Welcome to the Tuscany SDO Java subproject. We look forward to your
participation and try to help you get on board. Feel free to ask your questions
on the mailing list.
Here are some general guidelines we use in this project.
* Java SDO sub-project aims to provide uniform access to data from
heterogeneous sources which could be XML, RDB, POJO, SOAP, etc.
* Tuscany Java SDO is not just a reference implementation. We encourage
innovation based on the tenets of SDO. A lot of work we do provides feedback to
the specifications.
* SDO provides both a static (or strongly typed) programming model and a
dynamic (or loosely typed) programming model. This provides a simple
programming model without sacrificing the dynamic model needed by tools and
frameworks.
* It supports a disconnected model and provides Meta-data for easy
introspection of data types.

Setting Development Environment{bgcolor}
The Java SDO project Subversion repository is located at
[https://svn.apache.org/repos/asf/incubator/tuscany/java/sdo].
The repository can also be viewed online at
[http://svn.apache.org/viewvc/incubator/tuscany/java/]
Anyone can check code out of Subversion. You only need to specify a username
and password in order to update the Subversion repository, and only Tuscany
committers have the permissions to do so.
h4. Checking out code from Subversion
Use the command as follows (note that it uses http scheme so if you're a
committer change it to https):
{code}
svn checkout http://svn.apache.org/repos/asf/incubator/tuscany/java/sdo
{code}
h4. Committing Changes to Subversion
Any Tuscany committer should have a shell account on svn.apache.org. Before you
can commit, you'll need to set a Subversion password for yourself. To do that,
log in to svn.apache.org and run the command svnpasswd.
Once your password is set, you can use a command like this to commit:
{code}
svn commit
{code}
If Subversion can't figure out your username, you can tell it explicitly:
{code}
svn --username <name> commit
{code}
Subversion will prompt you for a password, and once you've entered it, it will
remember it for you. Note this is the password you configured with svnpasswd
not your shell or other password.
For more details check [Getting
Source|http://cwiki.apache.org/TUSCANY/getting-source.html]. Also for setup
details check [Establishing a Development
Environment|http://cwiki.apache.org/TUSCANY/set-up-sdo-development-environment.html].
Reference the code structure at [SDO Project Code
Structure|http://cwiki.apache.org/TUSCANY/sdo-project-code-structure.html].
h3. {anchor:Coding Guidelines}{bgcolor:#C3CDA1}Coding Guidelines{bgcolor}
There are a few simple guidelines when developing for JAVA SDO:
* The basic coding style used is described at [Sun Java coding
standards|http://java.sun.com/docs/codeconv/] but the main thing is to be
consistent with the existing code you're updating, so for example, if you're
updating a method that uses the braces on the same line style don't add code
with the hanging braces style.
* Always include the Apache License Headers on all files (both source code
files and resource files such as xml documents)
* Include a descriptive log message for check-ins, for example "fixed such and
such problem".
h4. Naming conventions to increase consistency
*Folder Names:* Please use all lowercases and dashes in folder names (like in
the jar names)
- Maven artifact id = tuscany-<folder name>
*Package names:* Package names within modules should include the module name so
that source code can be located in the source tree easily.
h3. {anchor:Testing}{bgcolor:#C3CDA1}Testing{bgcolor}
Tuscany uses plain junit test cases to perform unit and integration testing.
You can check [Test
Cases|https://svn.apache.org/repos/asf/incubator/tuscany/java/sdo/impl/src/test/]
for some examples.
(on) Note that we use surefire maven plugin to run the unit and integration
tests, and in most cases, they are configured to match a \**/*TestCase.java
file name pattern. Because of this, if your test case has a different file name
pattern, you might execute it from your IDE of choice, but the maven build
won't execute the test.
h3. {anchor:Maven Build Structure}{bgcolor:#C3CDA1}Maven Build
Structure{bgcolor}
_We use the term Module to refer to the leaf of maven tree._
* All poms will use the pom from the parent folder as parent pom
* Group id: org.apache.tuscany.sdo
* Version of our modules will be specified once in java/sdo/pom.xml, child poms
don't need to specify a version as they get it from their parent
* pom names begin Apache Tuscany SDO
* Eclipse projects are generated for all built modules using mvn \-Peclipse
eclipse:eclipse
h3. {anchor:Providing patches}{bgcolor:#C3CDA1}Reporting issues and providing
patches{bgcolor}
You are very welcome to help us develop Tuscany SDO Java. You may have ideas
that you want to pursue yourself or you may wish to pitch in with the design,
coding and documentation. If it's the first of these two then please put
forward your suggestions on the [development mailing list|mailto:[EMAIL
PROTECTED] If it's the latter, then feel free to ask on the
[mailing|mailto:[EMAIL PROTECTED] list or browse the issue tracking.
