I made a text editor in java. It has a FileExplorer class which allows me to read and write to a file. Now I would like to know how I could open said file (text.txt) with my editor application from outside my application. Basically when I double-click on the file (text.txt) it should start my application and pass some variables(like name and path). The application is a .jar file.
I am not going to bother anyone to go through the 2k lines of code, so I won't post it in here. But it is just a JTextPane in a JFrame and a PrintWriter/BufferedReader reading and writing to the file.
PS: should preferably work cross-platform.
Thanks
This question is not about java. It is about mapping files to specific application using you OS tools.
If you are on Windows you have to map extension *.txt to your application. Take a look on this article for details.
Please note that your application must accept file path in command line.
To make association easier I'd recommend you to writer batch file that runs your application and also accepts file name in command line. Then you just have to associate your batch file with *.txt extension.
If you are on Linux association technique depends on your flavor, but you can google it. Obviously you will have to create shell script instead of batch file.
EDIT
Actually your question is mostly about installation process. There are a lot of installation tools that can do this work for you. Some of the tools are even cross platform (I can remember "install anywhere"). There are both commercial and free tools that do this.

My JavaFX program needs to compute a file name path for various user-written files such as the product-specific preferences. For example, "Do you want to open your previous file the next time the program starts" and so on. I have successfully experimented with https://github.com/dlemmermann/JPackageScriptFX and "jpackage" for Windows at least, so it looks like I will shortly need a way to code, in a cross-platform manner, the "correct" path in which to store such files.
Is there a standard API or coding technique that will give me a file path that the program can write using user permissions that is "correct" for these native platforms?
I am not aware of a single piece of software which would do that but I think my answer to this questions Java - Cross-platform filepath may be helpfull for you. It also mentions how the same can be achieved on Android for example.
I have recently discovered the OpenDoPE project. From what I understand from the walkthrough, .docx files must be preprocessed to replace repeatable contents for example.
If I understand well there are 2 ways to do it :
Using docx4j
Using a Macro
I am developing a rails web platform, and I'd prefer the preprocessing to be done client-side, so with the Macro. But then If I can only do it with java, I'll go with it
Problem : when I click the "inject macro" button in the OpenDop Add-in in Word2010, nothing happens :O
So two possible answers :
Explain how I can install this macro in the document
Explain how I can have docx4j to preprocess the document. ie : from a linux terminal, what command with what parameters should I type to preprocess some document.docx file containing repeatable-contents ?
I tried clicking the "inject macro" button in my Word 2010, and it worked, that is:
it prompted me to save a .docm file
when i opened the .docm file in Word, the macro ran
Trying to open the macro in Word's VBA editor though, I couldn't. Seems I obfuscated it :-(
I do have the source files floating around, which I'd be happy to put on GitHub.
Please note however, that it is 4yo unmaintained 'proof of concept' level code (whereas the docx4j code is actively maintained and used by a variety of companies).
For non-interactive processing using Java, see samples/ContentControlBindingExtensions.java
To invoke from a Linux command line, that would need modifying slightly; also you need of course to pass a suitable class path.
The other way you could do it is by installing this simple web app in say Tomcat.
I have a team of users that have read only access to a shared network drive. Sometimes these users will need to deploy their project resources to the drive. I am trying to come up with a secure build process for them to use. Currently I am using a batch file that they can execute from their local system which will do the following...
User starts batch file
Batch file calls a java program (the credentials are 'hidden' and 'encrypted' within the java program)
The java program handles the encryption process and then calls a final batch file that actually runs the NET USE command to map the drive with admin credentials
The final batch file maps the drive, copies the required resources onto the shared drive, and then re-maps the drive with original user credentials (read only).
My major problem is that users will have direct access to the batch files that do this entire process and they could simply remove the #ECHO off command from the final batch file to display all the credentials to the cmd output window.
I'm not sure if there's a better solution to this sort of thing? Any ideas will be greatly appreciated!
Also, all machines are using Windows 7 and using a Windows network drive.
The best solution would be to copy the resources directly in the Java program using the jCIFS library.
A second option would be to map the drive from within the Java program. There's more information in this SO question: How can I mount a windows drive in Java?
There are some .bat to .exe compliers out there. Not sure how well they will work for your particular batch file, but probably worth a look. You can search for them. Here's a couple of them out there

I want to create my own file format for a particular kind of file. When someone downloads this file I want their system to know it should be opened with my application.
For example when I download a .doc file, my computer asks me whether I want to save the file or open it with Open Office. Similarly, If that .doc file is sitting on my desktop, and I double click it, it automatically opens with the correct application.
I believe this has to do with associating the file extension with the application in the context of the underlying OS.
Can any one point me to some good resources about how to do this in java?
Thanks.
Edit:
Sorry I want to clarify. Is there a way I can have my application associate the file type with itself when it is installed?

This source shows how to make a file association in windows:

You will probably have to do it per installer that you make in each OS.

I am a little new to programming so please bear with me. I create a lot of self-extractors that I upload to a ftp site which my clients then download (with the self-extractor putting the files I zipped up to the right spot). I am trying to automate this process on my end since it is rather repetitive.
I think I can figure out how to create the zip and how to upload the file once created but I cannot figure out how to create use winzip se to create a self-extractor from the created zip file. WinZip has a command line interface but WinZIp SE apparently does not.
Any help would be appreciated...I am planning on writing this code in java btw.
Thanks.
According to What are the differences between the full WinZip Self-Extractor and the Personal Edition version?
Self-extracting files can be created from the command line.
That being said, I'm not sure I would use Java to automate the tasks you are describing, it's not the best tool for that IMHO. I'd rather use shell scripting.
Update: (answering a comment from the OP) I'm really not a Windows specialist but I think that Windows PowerShell might be appropriate for the job (and it can be used to query a MS Access database).
If you need to compress and decompress zip archives, just use any other command line utility, which you will call from your Java app. For example zip, and unzip: http://www.info-zip.org/
7-zip is free and can do this on the command line, meaning you can make a batch script. 7za a -sfx MySelfExtractingzip.exe MyFolderContainingFiles/
