I'm searching for some good tutorials about implementations of uploading and downloading files (of different kind) in Java web services. I'd like to use latest Spring (core, context, web, webmvc), because I'm not into 'playing' with *.xml configuration files all the time ;). Unfortunately I managed to find only examples with writing own servlets. I’ve been told that easiest way for uploading is to use apache commons upload. Still I don't know an easy way for downloading.
I'd appreciate some example code or links to tutorials that would help. Thanks in advance :)
Let me google that for you "spring webservice upload file"

Problem:
I want to host static html pages (+ some imgs), but have them be uploaded to the host programmatically.
Current Solution:
I use github to store my html pages, and push my files to a remote repository using an API called jGit. I can view my website using an online tool that displays html sites from github's raw source code. People told me this is abusing github so I want to move away from doing this.
So I heard about Heroku. Is it possible to upload my files to heroku using jGit? Are there any limitations to this? Are there better/easier alternatives?
Thanks for any guidance in advance.
Heroku is to run your server, If you are just looking for static HTML hosting, explore GitHub Pages/ S3/ netlify
I would recommend GitHub Pages as you are already using GitHub.
I wanted to learn how to make a simple Spring+Hibernate+MySQL CRUD.
I found a tutorial. I wanted to run it on my PC first(to check if it's working and then learn what particular lines do). I downloaded the zip file and changed couple of things like name of the package or name of the database, the Spring/Hibernate version and so on.
Unfortunately the program is not working.
Of course there is a possibility that the tutorial is somewhere wrong but I bet that it's me not the tutorial that screwed something up.
If anybody have some free time I will really appreciate any help :)
This is a link to a github repo where I put code.
I use Eclipse and Tomcat 9.
Thank you in advance!
There is a lot easier way to get started with Spring completly from a scratch.
It's called Spring Boot and it is composed of an embedded servlet engine (Tomcat) and takes care of configuration of almost everything.
It doesn't require XML configuration which is a blessing and makes you feel like 2017, not 2000.
I found this video tutorial a very useful one and I can recommend it to you:

Also, this series of video tutorials is excellent and explains everything about Spring MVC and Spring Boot, but it seems that first video is missing..

How can I upload and download images with spark as our web layer?
I found this example but it heavily relies on Jetty being the container and does not work for Tomcat.
Would love to see a full example.
Why not just use a standard servlet with built in functionality?

I would just like to ask if there is a way to upload files in GWT WITHOUT using the Google App Engine and Apache Commons archives? I've been searching for ways to upload files in GWT but all of the solutions I find all make use of these two. I would just like to know if there is a way, because our app won't work if we use GAE and Apache Commons... Thank you very much!
Yes, the simplest would be (assuming you are saving files to Blobstore):
On GWT side use FileUpload. Here is an example on how to use it.
On GAE side use BlobStore upload handler.
The other option would be to use gwt-upload with GAE upload handler.
GWT does not have such feature. You need to use some existing library or handle multipart form submits by yourself (FileUpload class). There is for example a gwtupload library which I have used and it worked pretty fine (but it is based on commons-upload AFAIR). There are other libs for sure.

I have used Jazzy for web application. You have to these API in your jsp. You can also play with AJAX as well. If you application deployed in single environment and not stable then you have take care of dictionary where Jazzy put words. Because when you add words it will be stored in the file. That kind of difficulty you can face in if an application multiple server. Please find tutorial.
