Hello, All!

I have fought with ZK Studio activation for a few hours, so I want to share found solution with all.

First of all, the environment:
- Eclipse J2EE 3.6 SR2 x64
- ZK 5.0.6
- ZK Studio 1.0.0


How the problem was looked:
I called "ZK Studio Activation" form, typed correct username/password, "Status of Actvation" progress bar appeared BUT no progress had been started and I had to skip process and close form

All Eclipse network parameters are set well - I use remote installations and updates.

In Eclipse log I saw:
"!MESSAGE null
at [org.zkoss.eclipse.services.license.core.LicenseManager]
!STACK 0
java.lang.NullPointerException
at java.lang.String.<init>(String.java:515)
at org.zkoss.eclipse.license.util.LicenseReader.read(Unknown Source)..."

and

"!MESSAGE Unhandled event loop exception
!STACK 0
java.lang.RuntimeException: java.lang.RuntimeException: cannot load any license from environment
at org.zkoss.eclipse.services.ui.ZKRegistrationUIHelper.storeUserProfile(ZKRegistrationUIHelper.java:313)..."

And the solution:
1) locate JRE which is used by Eclipse
2) go to <jre folder>/lib/security, find file java.security
3) in this file the list of security providers is provided, it's elements look like security.provider.<N>=<provider class> where N is just order number
we should add the following provider
security.provider.9=org.bouncycastle.jce.provider.BouncyCastleProvider
9 - it's the next order number in the list
4) copy bcprov-jdk15-143.jar to <jre folder>/lib/ext (you can find this jar inside <eclipse folder>/plugins/org.zkoss.eclipse.services_1.0.0.v201101111416, /lib folder)
5) restart Eclipse and try to activate ZK Studio

Hope it will be helpful!

Alexey

Hi All,

In my case ZK Studio is successfully getting activated but still while working in ZK web application it is giving "The function of ZK studio is disabled,please activate ZK studio".
When I re-try to activate it,its again showing the successful message.
I am using Eclipse Europa on window OS and ZK version is 3.5.2

Any kind of help will be appreciated.
