Defining custom properties in the application panel - how to get the value in the code?

Question

In the IBM WebSphere Web Admin Console, you can go to Applications → WebSphere Enterprise Applications, select the application, and click the Custom Properties link. A page will be added to add key-value pairs. How do you access these values ​​from code? It seems that the properties do not fall into the properties of the system or in the ServletContext.

Answer 1

I have never seen it used during my 7 year career with IBM WebSphere Application Server. I think that if he ever used it so rarely that I would call this feature the left version of the previous version of IBM WebSphere that supported it.

For application configuration options, I highly recommend web.xml for web applications or @Resource annotation for web applications and other application types.

Answer 2

I tested this on WAS ND 8.5. Adding a custom property to the application adds it to the deploy.xml file.

I updated \ DefaultApplication.ear with the property name = "testprop" value = "true". Updated here:

C: \ WASNEW85 \ WebSphere \ AppServer \ Profiles \ Dmgr01 \ Config \ cells \ cell01 \ applications \ DefaultApplication.ear.ear \ deployments \ DefaultApplication.ear

The value shows:

 <properties xmi:id="Property_1424805152486" name="testprop" value="true" description="test-forum" required="false"/> 

Hope this helps.

Answer 3

This answer will not be entirely relevant, but it can solve the problem of defining and setting configuration properties for web applications managed by WebSphere.

The easiest way to define configuration settings for a web application in WebSphere:

• Define the parameters of the web application using the servlet initialization parameters:

web.xml

 <servlet> <servlet-name>my-servlet</servlet-name> <servlet-class> my.servlet.ClassName </servlet-class> <init-param> <param-name>someConfigurationPropertyName</param-name> <param-value>This Value Can Be Set</param-value> </init-param> </servlet> 

2. The value of these servlet parameters can be changed using the web administration console, you will find and can change them in Enterprise Applications > your-web-application-name > Initialize parameters for servlets
