Hi Experts,

I have installed the Java Web Dynpro server on my computer and Web Dynpro Development Studio.

I then started the sever and created a Java Web Dynpro program. When I try the deploy and run the application, it prompts a message as follow:


Deloying projects 'Test' (Time of error: July 24, 2008 12:43:26 PM EDT)
Reason:
Can't determine deploy mechanism.
Please check if there is a correct default system specified in SAP System
Registry preference page and if this SAP System is currently up and running.

Thanks in advance for your help.

Hey, thanks to your help.

I could create Java Web Dynpro program and deploy and run the program last week.

However, it suddenly generate the following error message since yesterday. As I have installed several different

versions of Java in my computer, I have uninstalled all the other versions and only kept JDK 5.0 update 16 in my computer.

I then reinstalled the Web Dynpro Development Studio. Unfortunately, I still get the error message.

Can online experts help me? Your help is greatly appreciated.

Hi,

please check that the JDK compliance level is at 5.0

Window->Preferences->Java->Compiler->Compiler compliance level set this to 5.0

Set the installed JRE to the one you have mentioned JDK 5.0 update 16

Window->Preferences->Java->Installed JRE's->

Click on the add button to select the path of your JDK.

once completed click on the check box next to it.

Regards

Ayyapparaj

Anna,

Register your system under 'Window->Preferences->SAP AS Java' with correct instance number. Mark this system as 'default' as well. To check for correct instance number, open 'sapmmc' on your server and look for the node with ICM under it. It should work after that.

Hope it helps.

Vishwas.
