Create Class and Package in Web Dynpro

[Former Member]

Hi Buddies,

as a Java Programmer, I would like to create a Package and a Class in a Web Dynpro Application. What I mean is a simnple Class that contains Constants etc. that is independent of the "generated" classes...

Where can I do that and what are the best practices?

Thanks, Johannes

Hi Johannes,

You can create. You need to follow some steps:

1. Goto Web Dynpro Nevigator.

2. Right click on the packages folder and then New->Other-> Java -> Select Class or Package.

You can run java class from NWDS also and able to see the output without deploying the web dynpro application.

Goto Run->Run As->Java application.

Hi,

Switch to Navigator view.

Under the src folder you can create the classes as you do in Java perspective.

To store Constants, is this the proper and common way to do it? Thanks, Johannes

Hi Johannes,

Yeah.

You can create a java class for constant and you can call the java class from Web dynpro by creating its object.

hey guys....thanks all...i thought it wasnt possible to use it that way...however....what could be call as a good practice....create the class within the WD package or create another DC for all utility related classes...since the latter helps in segregation of classess...i think the latter would be a better option....

If you need type-safe access you can define an interface with static final attributes representing the constants, or in JDK >= 5, use enums. Another option would be to use a property file.

In any case make sure to put your files under the src/packages folder.

What about this Interface?

IConstants

Seems to be defined by default in a Web Dynpro Project??

In fact, I was looking for a construct providing key, value pairs.. Is there anything out there?

Hi,

You can do it.

Goto File -> New -> Other -> Java -> Select Class or Package

I dont think that its possible to create a normal java class within a WD 4 JAVA project. However you could create a java project dc and use that dc within a WD dc and then call the classes you need.

My apologies its possible
