(How) is it possible to let the user store a file (via save file dialog) on the local harddrive via a java applet?
Is there any workarounds for this or do I have to apply for some sort of certificate somewhere?
For example, when printing from a Java Applet the user gets a dialog asking for permission, is it possible to do something similair in this case?
You have to signe your applet http://java.sun.com/developer/onlineTraining/Programming/JDCBook/signed.html, or you can use the WebStart technology.

I need to upload a file to OneDrive, via the command line. This will be done through a batch file which is distributed to end users.
From searching on Stack Overflow, I find questions like this one which say that you need to register an app and create an app password, using Azure. I don't have the necessary permissions to do this in the organization where I work, nor can I do anything that requires an admin account. So I can't any install software - I have to use what comes with Windows 10. I can't use VBA either as that's blocked.
I've managed to download files from OneDrive without anything like that, using the process described here:
Open the URL in either of the browser.
Open Developer options using Ctrl+Shift+I.
Go to Network tab.
Now click on download. Saving file isn’t required. We only need the network activity while browser requests the file from the server.
A new entry will appear which would look like “download.aspx?…”.
Right click on that and Copy → Copy as cURL.
Paste the copied content directly in the terminal and append ‘--output file.extension’ to save the content in file.extension since
terminal isn’t capable of showing binary data.
Example:
curl https://xyz.sharepoint.com/personal/someting/_layouts/15/download.aspx?UniqueId=cefb6082%2D696e%2D4f23%2D8c7a%2
…. some long text ….

cucg=1’ --compressed --output file.extension
I tried to do something similar after clicking 'upload' on the browser, but didn't find anything useful when trying to filter the requests.
I found these two questions but there is no keyboard shortcut to upload, AFAICT. Also the end user will be uploading a file to a folder I've shared with them from my OneDrive. Opening Chrome or Edge as a minimised window is fine, but I can't just shove a window in their face which automatically clicks on things - they won't like that.
It's just occurred to me that I might be able to use an office application to Save As the file to the necessary onedrive folder, where the keyboard shortcuts are pretty stable, but have no idea how to achieve that via the command line.
The best and more secure way to accomplish this goal I think is going to be with the Rest API for OneDrive.

You still need a Azure AD App Registration (which your admin should be able to configure for you), to provide API access to services in Azure. Coding with the API is going to be far easier and less complicated, not to mention more versatile.
I'm using ajaxfilebrowser on my webapp to browse a webdav folder for each user.
When i use the online update fonctionality, ItHit lunch an applet like this:
I want to remove the name and the editor of the applet and set my custom parameters.
Is this possible?
This dialog provides information about the Java applet, so the user can clearly identify the vendor, name of the applet and where it comes from. It is displayed by the Java machine, you can not modify it freely.
However you can change the applet name and the publisher. To do this you will need to resign the applet with your own Java code signing certificate.
I want to know if this is doable and get some hints about how to achieve this.
I guess at least it would need a confirmation dialog to run the (possibly evil) macro.
I want to produce an OpenOffice document that will upload itself on save to a hardcoded URL.
Is it possible?
What are the rough steps to achieve this?
My guess is:
bind a macro to the save event
have that macro get the current file binary data
have it post this data to a URL
but before researching about how to do this I need to know if this can be done in the first place.
I don't believe you need a macro to do this, instead depending on your OS you can map a FTP or other type of protocol remotely.
For example in windows you can "Map" a FTP as a drive and this would do exactly the same thing as your describing, you open the file from the FTP and upon saving it will then be written to the remote server. FTP is just an example here, there are other platforms you can use.
If you are at all interested in this method then following the instructions below, otherwise disregard.
Mapping a Network Drive in Windows Vista and 7.
Click on Windows start orb and then click on "computer".
Click on map a network drive.
Map a network drive will then open a new dialog box where you can click "connect to a website"
Simply follow that easy to use wizard and click add a new network location (Choose a custom network location)
Type in your FTP address, including username and password.
Finally name your network location to whatever you want.
Just a suggestion, I really don't think you need any macro unless you plan on distributing these files to other people then yes, but they would need to install that macro/plugin on their open office since there is no way to encode the document itself with such features as far as I know.
How do you distribute other files needed by your application that aren't in a jar file? For example, the application at http://www.javabeginner.com/java-swing/java-swing-shuffle-game . The download contains Shuffle.jar, Shuffle.bat, Score.dat, and an images folder with 3 images in it. I can see possibly putting the images directly in Shuffle.jar, but you wouldn't want to put Score.dat in the jar file because it changes. Is there somewhere you could identify this type of file in the jnlp?
The non-java files should be stored as resources. For files that change, you store the original or template file also as a resource in your jar. When the program starts, you have it check the local system to see if that file exists. If not, it creates the local file by copying the template file from the JAR resource. If the file already exists, then it is used as is.
To save files to the local system, even when running in the sandbox (unsigned), you can use the PersistenceService (javadoc / example). If your java application is signed, then you can use the regular File apis to write the file to the local machine, such as in a ".yourgame" subfolder under the user's home folder.
You can put all those files (except the scores file) in your jar file and load the contents using resource loading.
I've just deleted and restarted my reply twice now, changing my answer each time; this is confusing and needs a bit more clarification.
Are you SURE that application is supposed to be a Web Start app? On the site you linked to, it doesn't appear to be. Are you trying to take an application that was not designed as a Web Start application and change it into one that can be Web Start?
If it's not a Web Start app as your tag implies, then this question is open ended. You can distribute it 100 different ways.
If you are indeed trying to convert it into a Web Start app, you can start by packaging the images into the jar and that will alleviate your first headache if you just read them from there instead of from a File(). If it's going to be Web Start, then you need to decide how you want to keep scores. You have to decide what the scoring system is like before you can decide on how to go about it; will all the scores be kept on the web site hosting the Web Start app? Will that part still be local? If you want to get access to the local file system, you need to sign the jar, then you can extract the score.dat to the file system and do whatever you want with it if the end user accepts.
You need to figure out what you want to do before you can do it, or at least clear it up for us if you already know more than we know you know.
I was wondering if anyone knew of a widget that I could use to list/open a local/remote file within the GWT.
I thought I could use the FileUpload object but I can't figure out how to tell it where to browse.
Is it possible to tell the FileUpload object to look somewhere other than the local filesystem?
If not is there a simple widget where I can point it to a directory albeit local or remote via RPC?
Thanks,
C
This isn't a GWT issue, it's an issue of what's possible within a web app. Web apps cannot browse the local hard drive using only JavaScript and HTML, nor can they browse arbitrary remote sites.
You can create a button that when pressed, prompts the user to select a file from their local computer. Your web app then gets access to the path to that one file - but nothing else.
To actually browse local files within your web app, the only solution is to use Flash or Java.
