[opencms-dev] Impossible to use jsp declarations ?

[Alexander Kandzior]

Nicolas,

you can't mix JSP declarations <%! ... %> with JSP output like <%= xxx
%>. This is so in all JSP, and it is not related to OpenCms. 

If your really need to write to your JSP inside your method, you must
pass the "out" object from the JSP to your method on calling. It would
look like this on your JSP:

<% listFilesAndFolders(out, cms, uri); %>

In your method, you need to use 

out.println("something");

Best Regards,
Alex.
