Hi Raghu,

It was working earlier with JDK 1.8 after changing some file but now I uninstalled 1.8 and installed 1.6 which is not working.Please help.

Thanks,

Nithin.

Hi Nithin,

As suggested by raghu did you check the JDK version is [32 bit or 64 bit]?

For ex: If NWDS is only 32 bit and you have windows 64 bit version. when you try to open NWDS it will search for the JDK 64 bit version which will be available in program files and not to program files(X86) folder.

Did you completely un-installed the JDK 1.8 from your system.

Check the java folder in program files as shown below

C:\Program Files\Java\jdk1.8.0_20\bin\javaw.exe"

If you find both the versions 1.6 and 1.8 are available,then completely un-install 1 of them and try again else NWDS does not know to which version to take.

Also follow the below procedure.

Windows --> control panel --> Small icons --> JAVA -->

If you find multiple paths enable only the compatible platform to open NWDS and remove the remaining paths.

Hi Nithin,

You must install 32 bit version of JDK as it is only supported.

https://nwds.sap.com/swdc/downloads/updates/netweaver/nwds/nw/731/doc/prerequisites.html

JDK version

Supported Java Development Kit (JDK) are from SAP AG or Oracle. Note that the JDK you use must be the 32-bit version. You can either use:


JDK provided with the SAP JVM 6 "Windows Server on IA32 32-bit". 
You can start the installation process from here.
JDK from Oracle. 
You need JDK version 1.6 (1.6.0_7 or higher), 32-bit. You can download a JDK from http://java.sun.com/javase/downloads.

Note that for deployable applications, the JDK version of the Developer Studio must be the same as the JVM version of your application server.

Regards,

Praveen.

Hi Bhargav,

Thank u for detailed reply. Please find the attached snippet showing JDK versions installed.

My OS is windows 8 64 bit so I installed 64 bit JDK.When I install 32 bit 1.8 JDK I am unable to launch swing tool ESR & ID.

Thanks,

Nithin.

what error is thrown when you try to open esr and ID?

Keep the same JDK and NWDS 32 should work.
