I would like the contents of what I put in here to save after I click a save button, how would I go about that? Anything I have tried finding online doesn't answer my question.

Search for a CRUD application, there're several good tutorials on CRUD apps, this is my favorite:

And please, node.js/electronjs and javascript are languages totally different from java.

I'm working on a web project and I am required to write some functionality that will
allow a user to upload images/videos, then display them. The problem is that when I start doing some research for how to accomplish that task, I hear a lot of people saying that I should not
save the images in my database, but rather to an external server then just upload the file path
in the form of a string to the database.
Now this concept is completely new to me so I don't even know where to look or how to start. I am
programming in Java and I am using springboot, and hibernate. Could someone please point me in the
correct direction, as I have been googling for hours and I have found nothing that shows me how to
accomplish this.
Thank you very much.
We are trying to develop a website for tracking the progress of pipeline and assets. I want to link progress data entered from forms developed in Java to GIS. We will be capturing all the lat and longs of pipeline stretch and lat and log of progress of work.
I need help in developing shapefile dynamically based on the progress and also to view that shape file in my webpage
The javascript API does have functionality for uploading shapefiles form your desktop into the browser, but you will need another tool to create those shapefiles based on the progress.
For uploading the shapefiles, see the example here: https://developers.arcgis.com/javascript/3/jssamples/portal_addshapefile.html
There may be more examples available at https://developers.arcgis.com/javascript/3/.
For creating the shapefiles dynamically, you could use ArcMap or ArcPro if you have those, or one of many python libraries to help write shapefiles. There may even be some Java libraries to help with this as well but I only work on the front end so I cannot help you there.
For something simple in context, the complexity of what kind of workflow to best suite your needs can range depending on these questions (and probably others I'm not thinking of):
Do you absolutely need to create a shapefile for this? Why can't you just push the form to a spatial database (e.g. PostGIS) and then return the XYs of the points or the string of XYs for line features, etc.?
Where is the source of the data & what is the format? Is it a PDF, text on an HTML page, a .csv file downloadable from a page, etc.? You may need to implement scraping (from a site) or download and update, or your data could be live streaming - these are all different workflows and you need to establish these boundaries before setting up your workflow.
If your end game are points, all you need is XYs in a table format to display in GIS software. If they are lines or polygons, it'd be a little different. Again - what output type are they and what are you trying to do with it (e.g. import into QGIS)?
Without these answers, it doesn't make sense for anyone to suggest something to you that could be totally impossible for you to execute. Please answer these and think through your workflow from beginning to end and/or visa versa.

Today I want to know how to get image URL from webSite,
I already read some questions and answers but they're not quite perfect for me.
The problem is, when I enter the site, there are some images. It's pretty easy that I get image URl by UI, But, it's really hard that I get image URL by Java Servlet and jsp. Sometimes, some image url is in only networks!
For example, http://map.daum.net/ <-- this site.
Enter the site, and see 'RoadView'. When you see Codes in Chrome(F12), there are no image sources in jsp codes. Only you can see in Networks!
How can I get image URL(source)? Is it possible?
ps. I can get image source using mouse and right click, but I want to get image source using java automatically :), so please do not write user's perspective.
ps2. I'm not very well using English, so there are so many mistakes and something like rude. I apologize for that.
So, what you want to do is to scrape a dynamic content of the page to extract some dynamically loaded data (an image url) from it. You did not tell us what programming language or environment you want to use. However, similar questions have been asked before, for instance this one: How to scrape ajax loaded content with jsoup. There are two frameworks named in the answers to this question: PhantomJS and CasperJS. Both are JavaScript frameworks.
i'm not going to post any code here because i don't know how to start doing it. Actually I need your help...
I am working with java (using netbeans, btw) and I have a database with multiple urls in a table (MySQL), and i want to get a screenshot of every url listed there, save it to my pc and then insert that screenshot (jpeg) in the url table. I was looking here on stackoverflow but i had no answer (not an automatic one, because i have to open a web browser and the aplication is supposed to be a standalone app) (The other option i found in this article -> (this) is unavailable.
In the same article i've read about the Flying Saucer Project, and maybe is the best option, but i have no idea of how to use it and i don't want to waste valious time reading every single thing that the project can do... so i'd appreciate a quick tutorial of how to use it.
Please, if u can post some code here would be great, but at least i'd like an answer of how to do this, or mambe some suggestions, that would be nice too. THANKS EVERYBODY.
You should take a look at CutyCapt:
CutyCapt is a small cross-platform command-line utility to capture WebKit's rendering of a web page into a variety of vector and bitmap formats, including SVG, PDF, PS, PNG, JPEG, TIFF, GIF, and BMP. See IECapt for a similar tool based on Internet Explorer.
Just execute the application from within your Java application. See Running Command Line in Java. The result would be something like::
p = Runtime.getRuntime().exec(String.format("./CutyCapt --url=%s --out=%s",
url, path));
I need to know how to perform the procedure, you already have read in the title.
You'll upload an image (e.g. a piece of text, an article) and on server-side the text will be recognized via OCR and stored into a database.
Which would be the best programming language for it? It should be a browser application.
I found the ocropus project, but how can I combine it to common web scripting languages like PHP? Is it possible at all? Didn't have worked with Python yet.
Or a totally different approach..? Java Enterprise?
Let's rock that,
Chris
maybe you can use this php library i use for recognize text from images and store the text readed into database
http://www.phpclasses.org/browse/package/2874/download/targz.html
download the rar package and run example.php and then example1.php to see how it works
here you have an image upload example:

hope this helps
