Deploy / Update / Undeploy with NWDS

[Former Member]

Hi all,

I'm developping a webdynpro java application. To test the application i deployed it on the netweaver server using the NWDS (netweaver developer studio) : application-->Deploy new archive and run.

Questions :

1 - If i update one page in my application, i need to deploy a new archive again, does this deploiement replace the previous one ?

2 - Should i undeploy the application when i don't need it anymore. For example the applications i deployed while testing ? if so, how to do so on NWDS ?

3 - Should i use this way of deploiement when we pass to production ? or is it just for developpement ?

Thanks.

Hi Maya,

When you deploy & run your webdynpro java application in NWDS , you have come to the following doubts,

1 - If i update one page in my application, i need to deploy a new archive again, does this deploiement replace the previous one ?

Ans. -> When you update one page in your application ,Afcourse, you need to deploy your application again, and it will surely replaces the previous one, as whenever you deploy and run the application, everytime J2EE server, makes a new class file. in it's workspace.

2 - Should i undeploy the application when i don't need it anymore. For example the applications i deployed while testing ? if so, how to do so on NWDS ?

Ans. -> Don't need to undeploy the app.

3 - Should i use this way of deployment when we pass to production ? or is it just for developpement ?

Ans.-> This is just for development purpose.

Hi,

For your first three questions answers are already given.

Regarding sap test id-

It is just a test id generated by server. it shows that you are testing the application on server. Once you use the application in portal this will not come. You can change the id to anything like 15,20 and run it directly from browser, it will work.

Thank's a lot evryone for your helpful answers.

Conlusion :

- In development :

- i deploy the application using the NWDS.

- the new version replaces the last version

- no need to undeploy the application not used

- In production :

- i deploy the application using the deploy tool on the J2EE server

hi

Its depends how to replace the version that is if

u upgrade the version then no need to deploy again

but if u r replacing the new version u need to deploy again

beacuse u class file is not available in the new version.

hi

*u neeed to deploy again . because once u deploy your class file will automatically created in the j2ee serveer so u need to diply again.

• local means you r creating application in your workspace that is within the system.

i hope your problem will solve

thanks

Hi,

Thanks for you quick answers.

When i deploy the application my URL looks like this :

.../webdynpro/dispatcher/local/....?SAPtestId=12

what does local mean ?

why does it have a counter SAPtestId = 1...12 ?

does this means anything special ?

if i deploy the application using the NWDI, shall i still have these parameters ?

thanks.

Hi Maya,

Local means simply within your system and SAP test ID is a special counter ID ,it comes in URL when u try to run your application.

Hi

.../webdynpro/dispatcher/local/....?SAPtestId=12

what does local mean ?

Here /local/ means that your deployment is local to your server. You can find this .jar file in directory path of you server as follows:

\usr\sap\J2E\JC01\j2ee\cluster\server0\apps\local\<ProjectName>

Hi,

1. You need to deploy the application once again if you make some changes to your application. It will replace the existing application with the new one.

2. If you want to remove the application then you need to undeploy it using the remoteGUI or from Visual Admin.

3. For a real time scenarios you should go for NWDI.

Hope this answers your question.
