In JDeveloper 12c there is a feature called add custom operator in view criteria, default operators are commonly using in many places, in some cases we need to have additional operators.

In sql developer we can use In clause parameter directly which jdeveloper doesn’t have by default.

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.

This is a very interesting issue which totally got me stumped as the application was working perfectly fine in 11.1.1.6 and then migrating the app to 11.1.2.3 resulted in the below error while uploading the file to a blob column.

Cannot create an object of 
type:oracle.jbo.domain.BlobDomain from 
type:weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB with 
value:weblogic.jdbc.wrapper.Blob_oracle_sql_BLOB@114

 Solution is as below.

This is the feature you must have been used to if you had used forms developer and I missed this with the previous version of jdeveloper, specially during the OAF development days.But here is the relief in the 11g version of JDeveloper.I noticed this option while opening the jdeveloper 11g version 11.1.2.3 and came as a tip in jdeveloper.

Lets see how we can use this option.
