I need to render an entire javadocs filestructure which is in plain html.
I need this to render the files using permissions. The user needs to be logged in in order to view the files.
I got a folder with .js .html and some other folders as well. I need these to be viewed by a user, but only if this user is logged in.
How do I allow Play! to return a set of these specific files, without having to modify them?
Googled quite a lot but to no avail.
Thanks in advance
You would have to create your own version of the assets controller that will enforce the auth-requirement, you could probably get it to work by just wrapping the built in Assets controller. If the javadoc is not packaged with play you could take a look at the ExternalAssets controller which can server arbitrary files from the filesystem.
If you do not already have a play app that you are including this in it would probably be easier to do this with a webserver, apache would for example allow you to do this with only configuration.

I'm new to Java and new to compiling. What are the pro's/con's of sharing java code that is compiled vs not compiled?
Normally you'd put the code in a source repository of some kind and that's how you share the code.
If you want the share the finished product, well, if it's a standalone app, build it into a full executable entity (using build systems, launch4j, etc – this gets a bit complicated to produce a fully stand-alone thing any end user with no knowledge of programming and nothing installed can just install and use) – and share that. If it's a webapp, host it someplace and share the URL.

I do program to parse html pages and store images. But I ran into a problem. This page is dynamically generated by JavaScript, it means when I download the source code of the page and there are links to pictures. Can you please advise how to bypass it? Alternatively, some příkalad to be in Java. thank you
Downloading page:

That is not as easy as it seems to be at first glance. You need a headless browser engine like PhantomJS or the like that runs the Javascript and returns you the generated HTML.
See this answer to get more information on that topic.

I've seen examples on how to download files programmatically, but they all use direct links, ending with .txt .mp3 .jpg, whatever. However, the link to the file I want to download isn't a direct link: it doesn't end with .extension. How can you download the file in this case?
When downloading over HTTP, the file name is usually set by the server in Content-Disposition header. If that is not present, it is up to the client to choose the file name (based on the URL or some other strategy). The extension can often be derived from the Content-Type response header. See this for some of standard content types http://en.wikipedia.org/wiki/Internet_media_type
Very stupid answer: You can just download it as all other files. Download it the same way as you do with urls with extensions.

I am trying to run simple static website through Jar file but not having too much luck.
The reason I want to run the website through Jar because I don't want end users to access my pages directly. For example, they should not have access to index.html page directly without actually starting my program which is built using java swing.
Things I tried:
Jar application works if I am running on the same machine where I created Jar using Eclipse because index.html page is fetching the page from local directory. which i know is wrong.
If I try using different laptop or desktop then my swing application does not open any kind of index.html through my browser.
So any suggestions?
Also, I was using Desktop.open(), Desktop.browse, getClass().getResources().getURL() .. stuff that I seen on other pages.
You need to copy your data or use a server like tomcat, jboss etc.

Whenever I want to export from my plug-in xml, it gives the following error:
How can I solve this??
Check, if the file D:\fastcode_new\plugins\org.fastcode_1.3.0\icons\sample.gif exists and isn't write protected.
It tries to delete the file samlpe.gif (in D:\fastcode_new\plugins\org.fastcod_1.3.0\icons directory). If the file is open in another program that can cause this problem.
Sometimes you might not think it is held open, but if you did open it in a program before and upon closing the .gif program did not release it properly, it still counts a being held open. In this situation the only thing you can do is close all programs thay you ever used to open the file previously.
