Auditing Code in JDeveloper 11g August 8
The 11g release of JDeveloper includes a utility to perform code audits without having to install additional plugins. While the information it provides out of the box is minimal, for some violations you can also ask JDeveloper to fix the code automatically.
The metrics it provides:
NOS: Number of Statements in the construct.
V(G): Cyclomatic Complexity, a metric that captures the number of branches that can be taken through a method.
DIT: Depth of Inheritance Tree, this metric describes how far a class is from it’s furthest ancestor, or really, how many classes has it inherited from.
You can run audit reports on your projects pretty easily.
1. Select the project node in the Application Navigator.
Select the Project to Audit
2. Select Run from the main menu bar.
3. Select Audit Project.jpr
4. Choose All Metrics
View Audit Reports in JDeveloper
5. View the report in the log window
You can also run audit reports on rules violations. You can easily modify which rules you would like to include and which you wouldn’t along with which available metrics you’d like to include.

A couple things to keep in mind as you view the metrics:
1. The V(G) of RowImpl classes is going to be high because of the case statement within the getAttrInvokeAccessor method. This is normal for ADF.
2. The DIT is going to be above the default threshold for some of your Impl classes also, for instance, any Application Module Implementation. This is the class you need to extend is already so far down in the chain.
There are only a couple metrics that can be run from the audit tool built into JDeveloper and I’m sure there are ways to integrate other code auditing tools in JDev, but at least it’s a start.
One tool I was hoping to see which I imagine is a long way off is some type of auditing tool for ADF itself. Since so much of it is declarative and new, no existing tools are going to work on it, but it’d be nice to be able to audit the declaritive part of ADF projects for best practices.
