RSA Error: alt + / does not work

In Rational Software Architect (RSA) 7.5, I create a web project. And I would like to use alt + / hot key.

Root Cause
I update eclipse.ini to change RSA's language from Traditional Chinese to English. And the hot key had been changed to ctrl + after I changed RSA's language. But the hot key has conflict with my 輸入法.

How to Query Columns' Comments from Database

I would like retrieve comments from each column. The database is Oracle.

select table_name, column_name, comments 
from user_col_comments 
where table_name like 'NIGT%';


Utilize JDeveloper and SchemaSpy to maintain database schema & document

1. I need to change database schema frequently, and add comments for each column (it does not have any comments originally).
2. I have to deliver the up-to-date schema document to customer.

1. Use JDeveloper to maintain database schema and add comments for each column.
2. Use SchemaSpy to generate the up-to-date database schema [Concerning SchemaSpy, please refer to]


1. Download JDeveloper from

2. Launch JDeveloper after you installed it

3. JDeveloper workspace

4. Setup database connection

5. Check the connection in Database Navigator

5.Create a new Project

6. Choose "Generic Project", and click OK

7. Click Finish

8. Project had been created

9. Create Database Diagram from project

Before change

I have 80+ tables in my system, and need to deliver class diagram before deadline. Even worse, the schema keep changing. I need to find an automation approach to resolve this problem.

1. Create table in database
2. Use NetBeans to create entities and DAOs.
3. Import into RSA, and create entities/DAOs UML symbo from Java classes
(If schema change in the future, just repeat step2 and step3)


Create database connection in NetBeans

1. Create connection

2. Add jdbc jar file and click OK

3. Provide connection information

4. Assign schema name

5. Done

Use code generation from NetBeans
