Edit Web application context parameters at runtime

[former_member182374]

Hello Experts,

I've developed a web application on my J2EE.

The web application has some 'context parameters' (see image)

According to the following link:
https://help.sap.com/saphelp_nw73ehp1/helpdata/en/49/78d2d76a5d423ae10000000a421938/content.htm?
frameset=/en/49/78d2d76a5d423ae10000000a421938/frameset.htm₪t_toc=
/en/62/d678c5330a4992bc6fe927e6137c9d/plain.htm&node_id=58&show_children=true#jump58

It's possible to edit parameters at runtime:
"There are two options for configuring Web modules locally:
At runtime, using the SAP NetWeaver Administrator"

I don't want to edit web.xml and deploy the project each time I need to change a parameter...

So how do I change the parameters at runtime? (if I open NWA it's read only)

On version 7.0X it's possible by using Visual Administrator (see image)

J2EE version is 7.31 SP7.

Regards,
Omri

hi,

ServletContext.setAttribute method should do the trick for you..

http://docs.oracle.com/cd/E17802_01/webservices/webservices/docs/1.5/api/javax/servlet/ServletContex..., java.lang.Object)

Hope it helps,
D.

Thanks Daniel,

I'm aware of ServletContext.setAttribute but I want to set the parameters by Administration tool at runtime (like NWA).

The option was available in version 7.0X (see 'contextParameters7.jpg' in my original post).

Omri

hi Omri,

well.. I'm not totally convinced, but once I had the same problem.. I was able to modify this easily in 7.0 but as soon we did go 7.3, NWA was no longer allowing us to modify the context parameters for a web module.

I think using the Visual Administrator (another SAP Admin tool) you can modify them and restart the context in question.. but as far I tried, I was not able to do it using NWA.

sorry about my first response, but the thread subject mentions 'runtime' - I'm not too sure about runtime being the right word to describe what you are trying to do!

Hi Daniel,

I opened an OSS regarding this issue and I'll update the thread.

I don't see the point of init/context parameters if there isn't administration screen to update it.

As far as I know there is no "Visual Administrator" from version 7.1 and upwards (only NWA).

Omri

I got an official answer from SAP:

I have checked the plug-in and it turned out that it has read-only features.
The parameters are not meant to be changed via that plug-in.
You will need to redeploy your application in order to change the
context parameters.
