iframe loading from a local directory is restricted in most of the modern browsers. It is a security feature which you must toggle off to view the contents.

You can use relative path instead.

My suggestion would be to get rid of that iframe if you are developing a modern web app and explore latest ways of dynamic content loading.

If I were you, I would have used JQuery in my webapp to fulfill the remote loading

Here is a sample code

In place of '/remotesite/result.xml' , you can give the url of the xml hosted in the third party server.

Note: JQuery is one of the many options available.

When you are loading the xml response from a third party server, what is the need to load it from the local file?
You can write the response and store it in the local file for record purpose but can't you use the response object from the server as it is to display?

If you want to display the XML contents as it is with all the nodes, you can use the text function in jquery. Replace the script tag with this

Checkout this tutorial on how to access files from the local file system.

Note: I haven't tried that myself.

What is the point of writing the XML to disk? Can't you keep the data in memory? It sounds like it would be used pretty much right away, yes?

Time to rethink about your approach.

Having a servlet write a file, only for the JSP to read it, is bad. Not only because JSPs should not do any I/O, nor perform any kind of processing, but also because this is what request attributes are for. The servlet should perform all processing, and then set request attributes with the results, so that the JSP only creates the view, but not do any processing.

(I am assuming, of course, that the request gets forwarded from the servlet to the JSP. You haven't said one way or the other, so let us know if it's not the case.)
