I have an applet java displaying images from folder ,i cant run this applet using html i have this error :
The error you are getting is because your applet is trying to read a file from a directory in the local system where it is getting downloaded. This is a standard security feature. This of this way, you go to a website which downloads an applet and read a file or executes an .exe in your local system. Naturally this should not be allowed for an applet / javascript or code served from a server.
You need to create a signed applet. Please go through the following link to accomplish your need :

I am using Selenium and I need to upload an image to instagram. But at the time the windows file selector opens I could not get it to search for the image and upload it automatically
Up to this point my application opens well, when it goes to the point of selecting the file it does not do it automatically
I tried using the following codes without success
driver.findElement(By.className(name)).send_keys('C:\\path-to-file\\file.jpg')
But it gives me back the value of the second photo, that is, it generates a file selector from the main folder and not the one that I pass through as a parameter
I am using the following versions:
Java: 8
Selenium: 3.14
ChromeDriver: 76
Normal browsers don't allow JavaScript any access to the local disk. This is basic security. Imagine what would happen if you visit some site and it reads your local password file or any other important data without asking you.
If you want to upload files, take some standalone application or write a small utility that will do that. For instance, try instapy, you can find it pypi.org or on github. It is a matter of taste, the other can prefer other tools. Just try several tools and see which fits your need better.
The window opened for file explorer is not part of the browser and therefore it can not be interacted with via selenium. The solution to this is a software called AutoIt. Use the following link for a guide on how to use AutoIt for file uploads : Link
I'm running a Java web application using Tomcat and I've got my Java classes and .jsp files rendering the web. I am trying to implement a feature where you search for key words within files and then return the files so the user can download them from the webpage.
I want to store the files within a local directory, as the server will eventually be running off a local Linux machine. However, I am unable to get the path to the file to work on the HTML side. In Java I can easily do :
final File file = new File("/home/user/resources");
Which will find the files in there. However, in HTML I've been trying various URL's, including:
a href="/home/user/resource" download>"Name"</a>
However it cannot find the file, I gather this is because it's looking within the web application.
So, my question is. How can I get the HTML side to find the same files, in the same location as Java? If it's not possible without storing the files within the web app, is there a way to serve up the file from the Java side and make it available to HTML?
Also, the files I'll be storing will most likely be Word files, .doc and .docx.
Thanks for your help in advance.
Let me know if you need any more info.
EDIT : Updated download link within the .jsp file and within <% %> tags.
<a href="file:///home/simon/resources/clientInfo/" + entry.getValue() + "\" download>" + entry.getValue() + "</a>
Chrome complains of a network error.
You can do it with file scheme. Without the file scheme the browser assumes that your file is relative to the webpage and tries to resolve the file by making a request to your webapp.The file or link needs file:/// added before the your jsp's <%=path%> variable, so that the browser knows it needs to open a local file on the user's machine.

I have an application that uses a "signed" applet which is packaged inside a jar that does the following things:
Checks whether the file exists in the directory while uploading a file and opens a form for details.
An applet is included in JSP and checks the file exists in local system by getting storage path while uploading.
Checks whether the applet is active and downloads the file to local system.
Add files to application that will be stored as local copy in file system.
As the support for applets is getting removed, I would want to migrate from applets. I would like to know is Java Web Start the best option for replacing applets in terms of "security, trusted code" and signature. Are there any other technologies that comes useful for my application in the above areas?
Also found that
Migrate Java Applet to what/where?
Replace Applet in downloading and executing a file
Any suggestions on this?
I have created a simple Java application containing buttons, text fields and so on. I have created the JAR file and also the JNLP file for it and had it signed by Jarsigner.
Now I want to be able to run the java application (Java Web-Start) from a Google App Engine project. I used:
< a href="/.../mycode.jnlp">Launch application< /a>
This would work on a normal html page but does not work on my Java App Engine project which uses JSP pages. If I click the link on App Engine, it just downloads the JNLP file and doesn't run the java program.
I have searched for solutions to this to no avail. Any help would be appreciated!
I would like to load remote applets into my own applet.
For example, lets say I want my applet to download and display a game from this site within my java applet:
http://www.java4k.com/index.php?action=home
How do I do that?
You can use a signed applet to access the local file system and bypass the same-origin policy.
The LWJGL java library has developed an "applet loader" you can modify and reuse.
http://lwjgl.org/wiki/doku.php/lwjgl/tutorials/applet
Here is an example use in the wild: http://www.paulscode.com/demos/SoundSystem/09AUG2009/Helicopter.html
Basically, the applet_loader downloads a bunch of file, write them on the disk, add them to the classpath, instantiate the target applet, and then proxies Java methods call on it to the target applet (Applet.start, Applet.stop, etc..).
