Extensions on QlikView Server

pere_marti — Mon, 26 Jan 2026 16:26:21 GMT

Hi,

I'm trying to run an extension I have checked on QlikView Desktop using QlikView Access Point. I have copied the extension folder into C:\ProgramData\QlikTech\QlikViewServer\Extensions\Objects but I cannot see the extension.

In order to confirm that it is not a problem of my extension, I have distributed "Extension Examples.qvw" document into my Access Point (and installed the corresponding extensions), but it haven't work. Am I missing any step?

I have read some posts about this topic on Qlik Community, but I haven't found the solution.

Thank you very much!

Activate High verbosity on QlikView server logging. You might find the answer in the logfiles.

Hi Jerry,

Thanks for your help. I have done what you recommended me, but after some "Request received" lines, the only error I have is the following one:

Error

TRANSLATION: The process cannot access the 'C:\ProgramData\QlikTech\WebServer\config.xml' file because it is being used by another process.

Does it make sense to you?

Thanks!

Not really.

Anti virus issue? config.xml being locked by the Anti virus program.

The error on the log file has disappeared, but I still cannot see the extension...

You are using WebView and not plugin?

Sometimes a restart of QVS service is needed for the Extension object to be loaded.

Hi Jerry, we restarted all the services in case, but it didn't work. We are accessing via QlikView Access Point using "Full Browser" option, but it doesn't work.

Is it an Object extension or a Document extension?

We have seen errors in the log files when we have used extensions that didn't exist on the QVS. So it is strange.

Hi Jerry. I am trying to use the extensions I get from QlikView example (Extension Examples.qvw), this is Calendar, Org Chart, Mapping Example and so. I installed the .jar on my Desktop and copied the folders on the server as explained before. I agree with you: it is really strange!
