I am using Spring to create a web application in which a user can upload a zipped folder containing an index.html file along with all it's resources(pretty much like an Adobe captivate generated webpage). The user should be able to request the uploaded web pages in the form of inner web pages.
I can only go as far as unzipping the folder itself, but I have no idea how to launch the index.html present inside the zipped folder.
How do I achieve this?
Quite honestly Spring has no restrictions or advantages over
displaying your subpages inside another page. However you can use Spring MVC to dynamically serve the web pages from the uploaded folder.
More over you have to play the tricks from browser side. Going with iFrame seems to be the best option from client side, though there are many other options. Please check this thread.
You can write some smart APIs in SpringController which accepts the folder path or folder name as parameter, picks the necessary pages from the requested folder and serves the user.
Another approach could be to use a headless browser for the server side rendering and give the output as screenshots to client. This can render the pages server side. Please check this thread for more details.
I hope this helps you!

Currently using Wakanda 1.1.3 with a mostly Angular4 on client side, yet, a few prototype pages persist from
our initial project. Provided we make the necessary file structure, module, login and syntax changes for v2,
will Wakanda v2.4+ serve our older prototype pages?
If so, is there anything special or unique that we need to do to get a prototype page to load?
You can save the WAF files (JS & CSS) generated by the v1.1.3 runtime for each prototype page.
Open your prototype page in a browser.
Open the browser console.
Save both waf~css and waf~js files.
Hard link these files in your prototype page.
This should be enough to run on Wakanda v.2.6.0
I know this might be a broad question but i recently finished developing a laravel 5.6 app. I deployed it to a free hosting service (000webhosting) because i wanted the client to be able to preview it remotely from where they are without having to sign up for domains and hosting accounts and all that jazz.
I uploaded it by zipping my project folder and putting it in the directory of the cpanel. I put all the public files (including .htaccess) into the public_html folder and put the rest of the project into the parent directory.
Long story short, everything works fine except for ajax. Other non-ajax CRUD is functional but nothing ajax related works. It all produces 404 errors. The other non-ajax functionalities are in the same controller as the ajax methods! so i know the project is talking to itself. I have jquery library linked to on the hosted google libraries page. Is there some sort of convention that i'm missing that is limiting this functionality? do some web servers block ajax requests? It's working perfectly in my localhost wamp environment. What could i possibly look into to resolve this ajax discrepancy? If it comes to it, i'll pay for hosting, but i just want to make sure this isn't a consistent topic with many host providers where ajax needs to be specially configured or something.
github.com/maximus1127/drive ....this is the github repo. the file in question is drive/resources/views/auditor_pages/application_review.blade.php.
To login the browser, go to https://makemedrive.000webhostapp.com/ login with "aa#aa.com" pw "password". Click the instructors tab on the left, then instructor application, then view details. The "save notes", "background check/received" buttons are all the ajax features of this page and none of them work. They all produce 404 errors. Please help!
Thanks in advance!
A user comes to my site and inputs something, and my site generates a file as an output.
Unfortunately i cannot place the generated file on the public directory - as you all now Meteor watches this and restarts every time the public folder content is changed.
so my generated files lives in .meteor/local/build/programs/server/files
so for example i have document.pdf that lives in that directory, I'd like to serve/force/trigger a file download to my client's browser that lets his browser download this document.pdf file.
In general Its not a very good idea to do this. It makes it very hard to scale your app. Node isn't good at serving chunky static files either.
Then also if you have two servers there is a slight chance that the other one's data is requested (e.g if you use a download manager).
I'm not sure but I think Meteor's live code reload doesn't work/is switched off in when in production mode (when using meteor deploy or meteor bundle)
The best thing to do would be to upload your file to S3 and then redirect the user to the file there.
You can also use Iron Router and server side routes to create a dynamic file download.
See Iron Router Server Side docs. Then you set your content type to application/pdf and send back the file directly without saving it to the filesystem. If you need to you can also save it in some other folder and serve it up yourself.
Then have a peek at this answer for an example of reading in and streaming out a file:
Node JS file downloads using a stream.
Since this is a server side route, using express and Iron Router, you shouldn't have to mess with any of the fibers related async issues.
I am using HTML5 offline storage. The goal is to make the whole site available offline. So intuitively, no server requests means all the pages need to be on the client. The only way I know of to accomplish such a task is to make the site into one page then show hide portions with jquery when the user "navigates". Is there a better way?
The html 5 offline spec allows multiple pages to be saved offline so you don't need to put all your content onto one page.
EDIT: link to spec http://www.whatwg.org/specs/web-apps/current-work/multipage/offline.html
Be careful that your jquery does not still point to the cloud. You'll need to save the relevant .js files locally.
N.B. If your whole site can be generated and saved as individual .html files then all you need to do is to save these files in the correct (relative) directory structure.
in my home page I want to display user guide in two different format ( pdf and word) these documents were already created by technical writers and I want to show the download links to these documents in home page after the user successfully logged in. I can achieve this easily by putting these two documents in one folder up to the 'WEB-INF' but it will enable anyone can download these files(without logging in). Could you advise whats the best way to handle this in spring mvc 2.5
I guess you already have some security support, so you can check whether user is logged in inside a controller code.
Then you can put your files into /WEB-INF folder and create a special controller for serving these files to the logged users. This controller will check that user is logged in and then forward a request to the target file. In typical Spring MVC configurations you can forward a request by returning something like forward:/WEB-INF/myFile.pdf as a view name.
Alternatively, if you use some security library, such as Spring Security, you can use its features to secure access to your files. In that case you don't need to put them into /WEB-INF and implement a specifal controller for accessing them.
