This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Hello, I have a class the purpose of which is to grab the HTML from a given URL or set of URLs that I hardcode in it. I have a JSP that I was given that already does this. I was told that I need to put it in a normal Java file so I can run it and test it and my code can be put where it belongs by another developer. So far I've worked a lot of the kinks out but I'm a little confused by what I got on another forum. Below is my code:
It is giving me some errors on pageContext, session, Globals, Constants, and out saying they cannot be resolved or cannot be resolved to a variable and I was told by extracting a delegate class to do the work you avoid pageContext and session and for the most part you avoid Globals and Constants. They said I would need to create some new methods for this but didn't give much more information to which I asked:
I know I'll need multiple methods. I guess the thing that confuses me are things like:
Should pageContext be a method and therefore this would be an object of that method?
For this what should session, Globals and Constants be? Should they also be separate methods and therefore I'm calling objects?
The various contexts request, session, etc are part of the servlet specification and available to the JSP because the JSP is compiled to/runs as a servlet. Glancing at your code, I suggest you remove those values (comment out) to see if thd code does what you want. Ultimately you'll want to isolate your code into methods on a class so you could invoke them from a JSP or anywhere else. You may need to work with the line 27 (indication of entry from index page) to see if there is a parameter on the URL you can set for this one.

Thank you so much after like 3 days it looks like it's working. Any tips on how I can get this to save the HTML file to a location?
