Print Service : invoke servlet

[Guillaume]

Hi Sebastian,

Sorry again for yesterday, i'll be less unpleasant.

I'll try to invoke the method in the PrintService first. According your recommandations, I want to extend the class PrintService from HttpServlet and write the method doGet in order to invoke the servlet ExportToImage with an URL.

Am I on the right lane?

Thanks

Guillaume

no ...

okay lets simply summarize the process as again:

1) Client calls add method in PrintServer => returns $hash
2) Client adds the $hash to the URL and requests the servlet as file-download
3) Servlet gets the whiteboard objects identified by $hash
4) Servlet generates SVG from Whiteboard Object List
5) Servlet generates desired Outputformat from SVG and returns it
6) Client receives files and is happy.

...

Yes Sebastian you are very clear on your description and  I understand step 1 3,4,5 and 6 no problem.

But the step 2, how do you request the servlet ExportToImage as file-download ?

I have read your last post and you said :

*but as I have written earlier, you need to invoke this method in the PrintService first, to create
the hash for the servlet. Otherwhise the servlet cannot find out where to get the whiteboard objects
that it should render. *
