Modifying the Java EE Application

GlassFish Server supports iterative development. Whenever you make a change to a Java EE application, you must redeploy the application.

To Modify a Class File

To modify a class file in an enterprise bean, you change the source code, recompile it, and redeploy the application. For example, to update the exchange rate in the dollarToYen business method of the ConverterBean class, you would follow these steps.

To modify ConverterServlet, the procedure is the same.

Edit ConverterBean.java and save the file.
Recompile the source file.
- To recompile ConverterBean.java in NetBeans IDE, right-click the converter project and select Run.
  
  This recompiles the ConverterBean.java file, replaces the old class file in the build directory, and redeploys the application to GlassFish Server.
- Recompile ConverterBean.java using Maven.
In a terminal window, go to the tut-install`/examples/ejb/converter/` directory.
Enter the following command:
```
mvn install
```
This command repackages and deploys the application.
