How to use subversion with jdeveloper for Oracle ADF development Part 1

It is a very rare sight that a project team with more than 2 developers doesn’t have any source control in place while working on an Oracle ADF development project.If you don’t have source control for Oracle ADF development, then your project needs a better project manager and architect :).

I had created a small project to demonstrate source control with Oracle ADF jdeveloper’s native support for subversion(SVN).We will use the code.adfapps.com for our subversion project hosting.

Below are the high level steps..

1) Create a manual connection to subversion repository from Jdeveloper

2) Click on the Application menu and say version application.

3) Select the repository connection and choose whether to version control to trunk,tags or branch(Put it in Trunk for the first time)

4) That’s it.. We are done with source control..No, there are lot of challenges still.We will cover them one by one in the 5 part series.

For now, let us look at the above steps in detail.

value:weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB@114
