I would like to get the list of available network printers, and allow users to install (add) a selected printer on their pc using a JButton.
I have searched the net and did find a java api called java printer api but this didn't help me.
Any suggestions ?
As you have probably realized, the standard Java Print service API is for printing documents from a Java application. It works by interacting with an existing printer or print service provided by the host system. It does not address the concerns of setting up or configuring printers or print services.
I would like to get the list of available network printers, and allow users to install (add) a selected printer on their PC using a JButton.
The Java printing APIs don't provide that functionality.
So there is no way to automate the install process? Execute a batch script maybe?
If it is possible to automate printer installation, discovery, configuration (or what have you) using a shell script or batch file that can be run by an unprivileged user, then it is possible (actually simple) to get Java to run the script.
Writing that script is likely the hard part, and it is not a Java programming problem. And if you can't write / find a script to do this, then your chances of doing printer setup from a Java program are about zero. While it may be technically possible to do the task in Java, it is (IMO) not worth the development effort to do it that way.

I have created a Java program that utilizes Chrome Driver, Selenium, and Java Excel API. The program is used to automate a few different processes on Google Chrome. Currently, setting up this automation is more complicated than I would like it to be: the user needs to download a zipped folder, unzip it, download the Java Runtime Environment, and launch the program using the executable.
My goal is to simplify the installation of the automation. Ideally, a user would come to a SharePoint website, fill out a form with the parameters of the automation (potentially upload an Excel Workbook), click an "execute" button, and the automation would run. As a result, the automation would run seamlessly across platforms (Windows and MacOS) without any modifications.
I have researched changing the programming language to achieve this functionality. I concluded that a different language could remove the need for a Java Runtime Environment download, but it would still require some type of installation process. Additionally, I have researched using HTML/JavaScript, but I concluded that this is not possible because the functionality (triggering a web automation from a website) could be used maliciously without the user's knowledge. Finally, I began researching containerization through Docker. This solution seems promising but I do not know enough about it to determine if it is the appropriate solution.
What would be the best route to achieve the results that I am looking for (outlined in the second paragraph)? I have access to enterprise-grade databases that I thought may be useful. Would it be possible to have the form trigger a virtual machine to run the automation on a remote database and then output the result to the user once it has finished?
Thank you in advance for any guidance you can provide. I do not know much about making a Java program into an enterprise-grade application so any information about what to research is extremely useful. Finally, please do not hesitate to correct my logic at any point in this question as I may have drawn the wrong conclusions from my research.

I'm trying to print on a printer full of functionality (Kyocera TASKalfa 5501i), having a mailbox add-on with 7 outputs installed. I want to print to each of those outputs indiviually using Java on a server. Because my application runs on a remote server, Java has no UI available to, for example, open the drivers default preferences-window and select the output-tray there. Until now i got all attributes working, that are in the javax.print.attribute.standard package, but i have no idea how to select the output-tray.
I searched nearly the entire internet for a solution. Does anyone have an idea how to select the output-tray/mailbox or pass, any non-default parameter to the printer without having to implement the complete printing-stack from bottom up?
Kind regards.
I am working on a project for my users to generate HTML pages, JS files, CSS files etc... through dragging and dropping visual elements and by going through a series of wizzards. The goal I am trying to achieve is to create an application in which users selects a runtime, for example tomcat or nodeJS and then be able to create content for that specific runtime in the manner described above. Part of this application would be the preparing of your runtime, and by that I mean installing tomcat or nodeJS for you. so the big question here would be, how do I run installers through program code ? (java 7/8 mainly)
what I have tried:
Using a strategy design pattern to determine the host platform and run a series of command in the terminal to execute an installer, problem here is that some installers start a wizzard and require further user input. and in some cases the host platform would require elevated permission. Is there perhaps a solution where one adds arguments to the terminal commands to skip an installation wizzard ?
Any help on this subject would be greatly appreciated.

Well what I am trying to do, in the long run, is to change some LAN properties when the an ethernet cable is connected to a computer.
I want to run my Java program each time a LAN network is detected. I found a couple questions as to how to do this in C++, but nothing related to Java, specifically. Would this just involve the way I distribute my final application? As in, I could use Jar2Exe Wizard to package my Java program as a Windows service and then just figure out how to run that at startup. But is there any way to do this within the Java program itself?
Don't know what your specific need is but you could try this. This shows how to run windows commands from inside java so you wont have to create an external batch file.

So I'm working on a project where I would like to be able to have the user browse the Active Directory to find a machine or workstation. I already know that you can envoke this directory search in the command prompt by using:
rundll32 dsquery,OpenQueryWindow
I'm using java for my project and I understand how to capture input from a command that I execute in the program but currently, at home, I'm not connected to a domain so I cannot test what the command returns when a user selects a computer or if it even returns anything. Could someone test this for me and tell me what it returns.
Also, if anyone has any better ideas on how to achieve this without relying on window's tools, like maybe a Java API for Active Directory Services?
Instead of calling an API function using rundll32, you should use a Java based LDAP library which will encapsulate the work in front of the Active Directory (so you won't have to parse the results by yourself).
Also, if anyone has any better ideas on how to achieve this without relying on window's tools, like maybe a Java API for Active Directory Services?
Choosing a pure Java library could help you run your application on many platforms (as opposed to using Windows' rundll32 which will limit you to Windows platform)

There are solutions for this kind of testing problems. You should read about mocking: http://en.wikipedia.org/wiki/Mock_object
Good luck!
