modify a mounted JSP / FSResource from a servlet

Hi,

to work with a JSP in Sling I mounted it to the Sling resource tree 
using "<Sling-Initial-Content>", "<mountByFS>true</mountByFS>" and so on 
in the pom.xml [1].
Now I would like to modify that JSP [2] using a servlet [3].
The servlet gets called and there I can modify the JSP content by 
changing and saving the corresponding node.
But the change doesn't end up in the JSP. Do I use the right approach?
I only found one [4] documentation about that. Is there more that I 
haven't seen yet?

One reason might be, that I use
`Resource contentResource = resource.getChild("jcr:content");`
in PUT.java:72 to get the resource and do the subsequent change because
´resource.adaptTo(Node.class);´ in line 75 returns null.

Does somebody have an idea on how to change the JSP using the servlet?

Any hint is appreciated!

Best,

Sandro

Hi,

the file resource provider which mounts the JSP does not handle changes,
it's right now read only. Therefore if you want to do something like this,
you either need to implement Create/update for the provider or directly
modify the file on the file system
