Create a .qvd with Java

Hello,

It's possible to create .qvd files with java, or other APIs ?

How/Where can I find some informations about it ?

Usually you can find such things in the APIGuide.qvw, in the Automation Reference or in the Java API - Documentation, all downloadable

You could use ExportEx. VBScript-Example in a.m. API-guide:

set obj = ActiveDocument.GetSheetObject("CH01")
obj.ExportEx "C:\test.qvd", 4

Don't know whether this function is also implemented for Java; but perhaps one could use the Java-To-Com bridge if it needs must be Java.

I find how it is possible to export data from application using Java, but I don't find where I can create qvd files from java generated data.

I'm afraid I don't quite understand what you mean by "Java generated data". Can you give an example?

i would like to use a simple java function to insert row by row, new data in a qvd file.

/*Open/Create qvd-file

loop tab n

qvd-file.insert(tab(n))

end loop;

save qvd-file;*/

This is not java, but this kind of stuff.

AFAIK that's NOT possible. Creating QVDs is only possible through QlikView, it's a special proprietary format, it's not just like writing to text files. You could as said by "controlling" th QlikView-API by Java, which would only be possible (so I think) as mentioned by a Java2Com-bridge.

how do we then integrate with any application.

For an ex: I have java app and I need to call qlkview functionality from my app.

You can have a load script that reads the data from a text file (the text file can be created by your Java application) and writes the data into a QVD..

Using Automation APIs, you can access your QlikView document, initiate a reload and trigger the process of reading a text file and writing a QVD.

I have a feeling that you are over complicating your need by trying to do everything in Java and call distinct QlikView finctions, instead of using QlikView in a more "complete" way...

Hi Ermance,

I'm working on a Java project to read/write QVD files:
