Hi
I'm trying to go through complete installation. Would you help me ?

What doesn't work with the application in multi-user mode:
I open the Protege.exe file. In the Essential Viewer tab, I enter the information.
See image_1 (attached document)

I click the Publish Repository button and it crashes.
Rendering repository...
Sending repository snapshot...
Checking for access...
Sending XML snapshot...
Exception encountered during send
Failed to send snapshot to the Report Service:
No response from the Report Service at this URL.

So by default, the application tries to take a snapshot in Essential XML mode and it doesn't work.
I go to the Essential Snapshot tab and select Essential XML and it crashes again:
See Image_2 and IMage_3

Caused by: java.lang.ClassNotFoundException: com.enterprise_architecture.essential.xml.XMLRenderer at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) ... 38 more
I decompile the module and extract:
C:\logiciels\Essential\Protege_3.5\plugins\com.enterprise_architecture.essential.snapshot
I see that the code calls a module that doesn't exist in the plugins:
import com.enterprise_architecture.essential.xml.XMLRenderer;

See image_4 and Image_5

Hi,

Did you apply the required memory configuration?

Let me know if this helps?

Hi,

Can you also confirm you are using Java 8?

Thanks
