#15756 — JAR file association on Windows 7 broken

I have somehow managed to break the file association between JAR files and 
Java on Windows 7 such that I can no longer double click on an executable 
JAR file.  How can I fix it?  Reinstalling the JRE has not helped.

I can right click on a JAR file and select Open With and then select 
java.exe but there doesn't seem to be a way to specify that that java.exe 
needs the -jar command line option to run them and so this doesn't work.  It 
correctly changes the JAR file icon to the Java icon but they still won't 
open on double click.

I think it should be javaw and not java.

And you need to get the command line right.

Thanks Arne but unfortunately they didn't solve my problem.  The first link 
doesn't apply to Windows 7 and both the utility and command in the second 
link made no difference (so maybe they don't work in Windows 7 either).  So 
I still cannot double click on executable JAR files.  I think once you have 
chosen "Open with..." it sets the association in concrete.  In my case it 
has remembered an incorrect command and I cannot see any way of overriding 
it.

This is a Windows question, not a Java question. Windows has the ability to 
associate command lines with an extension, including options. Look up how.

"Open with..." is only the common-case shortcut. You need to dig into 
control-panelish options to go beyond it.

You are such a hard task master Lew.  This question may not be directly 
related to Java _programming_ but it is related to getting Java to work on 
my machine which is necessary if I want to continue as a Java programmer.

Anyway, my Google skills must be a little lacking because I cannot locate 
any link which tells me how to do this in Windows 7.  The File Types tab in 
Windows Explorer has been removed in Windows 7 and the file type 
associations option in Control Panel doesn't seem to allow you to specify a 
command line.

That's not the point, and I'm not a task master at all. I'm simply pointing 
out that your question is specific to knowledge of Windows, and that this 
forum is not optimal for that topic.

Just because it's related to Java doesn't mean that Java skills will solve it. 
In this case it takes Windows skills.

I am so very deeply sorry to speak simple truth here. I assure you that I did 
not do it to offend your sensibilities but to suggest a more propitious approach.

I don't know if this'll help or not, but if Windows knowledge doesn't solve 
your problem sure as Hell is an icy place the cross-platform, independent 
viewpoint of Java isn't going to do you a spit of good.

But since you seem all bent out of shape that I profess not to be an expert in 
Windows 7 and that a Windows 7-specific forum might improve your chances of a 
good answer, I felt bad and decided to Google on your behalf. Again, I'm no 
Windows expert so maybe these links won't help as much as I most abjectly and 
sincerely hope they will.

<http://izt.name/soft/types/>

Based on the screenshots at
<http://www.winvistaclub.com/t19.html>
it looks like Types gives you access to the command line for the association.

I apologize but my abjectness and desire to help only extended to five minutes 
of Internet search on "windows 7 set file associations", but I noted that many 
of the links from that search seemed quite promising.

No worries and thanks for the links.  I am not at all "bent out of shape" 
and thankfully I have solved the problem by hacking the registry after 
reading Stefan's post.  As markspace also indicated, I am surprised that a 
simple reinstall of the JRE did not resolve the issue.

I am actually very glad you aren't upset.

I seriously do think that utility to which I linked shows promise, modulo my 
ignorance of Windows 7.

This does not allow you to specify a command line in the association.  It 
seems to be just another way to get to "Open with...".

Then back to the command line.

assoc and ftype do exist in Windows 7.

C:\>ver

Microsoft Windows [Version 6.1.7601]

C:\>assoc jarfile
jarfile=Executable Jar File

C:\>ftype jarfile
jarfile="C:\Program Files (x86)\Java\jre7\bin\javaw.exe" -jar "%1" %*

  On my page

http://www.purl.org/stefan_ram/pub/jar

  , I find:

jar.reg =

REGEDIT4

[HKEY_CLASSES_ROOT\.jar]
@="jarfile"

[HKEY_CLASSES_ROOT\jarfile]
@="Executable Jar File"

[HKEY_CLASSES_ROOT\jarfile\shell]

[HKEY_CLASSES_ROOT\jarfile\shell\open]

[HKEY_CLASSES_ROOT\jarfile\shell\open\command]
@="\"C:\\Programm Files\\Java\\jre1.7.0\\bin\\javaw.exe\" -jar \"%1\" %*"

  . To use this, you need to be proficient in the Window
  registry: only use it if you understand every detail and can
  assess all the risks involved, backup everything before use
  and use it entirely on your own risk. I also do not claim
  that it will solve your problem.

---------------------------------

Thank you!  That solved my problem nicely :-)

That's weird to me that a reinstall doesn't help.  You may have to clean 
out your registry.  (Maybe: uninstall, clean, then reinstall?)

But anyway, this link seems to describe how you can set file 
associations with command line parameters:

I consider that a bug.  See
http://mindprod.com/jgloss/jar.html#ASSOCIATION
-- 
Roedy Green Canadian Mind Products
http://mindprod.com
Why do so many operating systems refuse to define a standard 
temporary file marking mechanism? It could be a reserved lead character
such as the ~ or a reserved extension such as .tmp.
It could be a file attribute bit. Because they refuse, there is no 
fool-proof way to scan a disk for orphaned temporary files and delete them. 
Further, you can't tell where the orhaned files ame from. 
This means the hard disks gradually fill up with garbage.

That doesn't sound like the right approach.

You normally don't want to put anything into Java's own lib/ folders.

putting the jar in the ext dir would effectively put the jar on the
classpath, I it would not do anything to make

xxx.jar

on the command line execute the jar.  Windows  still would not know
jars are executable or what executable can process them.

Why do so many operating systems refuse to define a standard 
temporary file marking mechanism? It could be a reserved lead character
such as the ~ or a reserved extension such as .tmp.
It could be a file attribute bit. Because they refuse, there is no 
fool-proof way to scan a disk for orphaned temporary files and delete them. 
Further, you can't tell where the orhaned files ame from. 
This means the hard disks gradually fill up with garbage.
