JAR file association

Many of my customers have encountered problems with the .jar file extension being hijacked by some other program (usually zip/compression programs). There should be an easy way to restore this association (rather than re-installing Java!).
If anyone has a simple solution please e-mail me ( [email protected] ).
Thank you.

There is. I'm assuming that you're using Windows - just open the Folder Options | File Types, select jar files | Advanced, and restore the open action.
My XP Pro uses this action:
"C:\Program Files\Java\jre1.5.0_01\bin\javaw.exe" -jar "%1" %*Replies are only made here, so that others can benefit.

*.jar file association setting

I use J2Sdk1.3.1_04 with Windows XP professional. I have a problem with the *.jar file association setting and I need someone's help on how to correct this. Anyone?

In Windows Explorer menu: Tools | Folder Options | File Types, select jar file entry, click Advanced, and use what I posted to for the open action.

Making JAR File association under Win32

Hi,
Due to an agressive installation of a software on my system, I have lost my file association with jar files.
May someone help me setting it up again without having to reinstall the jdk by giving the correct parameters. I would appreciate.
Thank you

* open my computer
* select view | folder options
* select file types
* locate entry "Executable Jar File", and select edit
* select actions: open, then press edit
* browse for javaw.exe
* After you have browsed for javaw.exe, append to the end of the path the following: -jar "%1" so it looks something like this:
"C:\Program Files\JavaSoft\JRE\1.3.1\bin\javaw.exe" - jar "%1"
* click OK, and your done.

Associating executable Jar files w/ appropriate program

Hi, I'm kinda new to java but this question is more OS related I think. I made a GUI program that reads / writes files and does some other stuff, I compiled it, then made it into an Executable JAR file. I put the file on my dektop w/ the required resource file (contains the read files) and then I double-click it and lo and behold Win-Ace(R) popps up. I right-clicked on the executable jar file, associated it with JAVAW, double-clicked again and it worked. So i guess my question is, is there a way that it will automatically associate itself with the right program so when I give this program to other people, they won't have to associate it the same way?
Anyhelp would be greatly appriciated!

No, becourse even if java could do that it would make sence becourse to run the jar it must be associated with javaw.
But you could try to create a .reg file (registry file) that associate jar with javaw, when somebody runs the reg file it associate jar with javaw.
But I think you should make different reg files for different windows versions (not sure about that).
I don't have experience with how to write reg files but you just google.
But I should try it out on your own windows, you could install windows on another partion and try it out on that one (first make a image with norton gost or something so if something goes wrong you can fastly get back to the old state).
But you can also export your registry to a file so you can put the old registry back if somethings goes wrong.
Use these tips on you own risk!!!

How to Invoke a main class in a jar file from my project

Hi
I am a new user of the Sun Java Studio enterprise. I would like to know how i can invoke a main method in a jar file associated to the project.
regards
Nisanth

Could you please clarify: do you want to run your project or a project from an independent jar?
In the first case just select Run Project from the project context menu or select a class with main method and click Run File in the class context menu.
Regarding the second case:
- I don't think there is such a feature in the IDE (running third party jars is not an IDE function). Could you explain why you need this?

How can I create a jar file that will run automatically on double click

all the jars I created run only from the command-line.
how can I make it run by double-click on it?

First you will need to associate .jar files with the javaw.exe program in order to just be able to double click on the jar and run it from within a windows explorer application. Next you will need to set the main class attribute of the manifest file. My understanding is that the value of this attribute is used by the launcher to know which class to load. In other words, which is your main application class. To specify this attribute open your manifest file in a text editor. You will find this file located within the jar at META-INF/MANIFEST.MF. Then, add the line,
"Main-Class:<relative path to the main class>" However, remember not to add the .class extension to the end of the class name.
In Windows 2000 you can associate jar files with javaw by finding a jar file in Windows Explorer and right clicking it. This will give you a context menu which should have an Open With... option (if you are not using Windows 2000 and don't see the 'open with' menu item, try holding down the shift button while right click on the file). Select the Open With... option, then, when the dialog appears highlight javaw and select the "Always use this program to open these files" checkbox. When you hit the OK button you should have all your jar files associated with the javaw process.
Once you've done this, you should be able to double click on your jar file and run your application.

Deploying Runnable JAR Files

I recently started working with Java 8. I have been doing Java development on and off since the early 1990's. Most recently I have been doing all my current work in Java 6. I decided to "take the plunge" and to start getting involved with Java 8. I have an imaging application for geologic research I started working on in Java 6 and Swing, and I am now continuing that development under Java 8. It was a pleasant surprise that to find that all of my code built without any changes (I'm using Eclipse Luna and just deleted the Java 6 runtime and added the Java 8 runtime after downloading it). The application launches fine from inside Eclipse.
However I ran into a problem when exporting the application from Eclipse to a runnable JAR file and then trying to launch it. After creating the runnable JAR I was not able to launch it by simply double clicking. A command line box would open for a second, then close and the application window would never open. To upgrade from Java 6 to Java 8 I only downloaded the Java 8 runtime environment, not the Java 8 JDK. I am working in Windows 7 and tried updating the JAR file associations and experimented with various path entries in my environment variables. No mater what I did I could not simply double click the runnable JAR to launch it.
Then I deleted all my Java downloads and started over. This time all I did was downloaded the Java 8 JDK and installed it. I then pointed Eclipse to the Java 8 runtime environment that was installed with the Java 8 JDK. My code built and executed perfectly in the Eclipse environment. Then I exported the the Eclipse project as a runnable JAR again and tried to launch it. This time it worked as expected. Double clicking the runnable JAR launched the application!
So my question is if I want to give this application to someone to run (i.e. deploy it) that is not a developer, do I have to have them install the Java 8 JDK? I assumed that all someone would need to run the application as a runnable JAR is the Java 8 runtime environment, not the JDK. However, when I had only the Java 8 runtime environment installed I could not launch the runnable JAR. With the Java 8 JDK I was able to run the runnable JAR as expected, with no problem.
Am I missing something?
Thanks,
Mike

Unable to create an executable jar file

Hi,
I am unable to create an executable jar file,

Your jar is perfectly generated, but your machine has a problem with .jar file associations.
You have two options:
1. Play with the registry. Dangereous if you are not used to.
2. Reinstall the jre.
Just to verify my theory, open a command prompt and the command:
reg query HKCR\jarfile\shell\open\command
What does it say? I have executed your command , here is the output
HKEY_CLASSES_ROOT\jarfile\shell\open\command
(Default) REG_SZ "C:\Program Files\Java\jre6\bin\javaw.exe" -jar "%1" %*I am not getting anything from this command, can you please explain clearly.

Double click on jar file but does not launch

My PC has windows7 operating system
The jar file was working fine, everytime I double click it would launch, no problems
Somehow the .jar file association was changed to open with winrar so now when I double click it does not launch and run like before, winrar opens it
How can I change the file association back to java?

How do I install a JAD & associated JAR file on a ...

Hi all,
I have a Nokia 6288 which I would like to install a signed application in the form of a signed JAD and accompanying JAR file.
I need the JAD because it is a signed application, and I need the phone to recognise this because the application accesses user data from the memory card.
I have tried:
1. Using PC Suite. It does not recognise JAD files.
2. Copying the signed JAD & the JAR file onto my memory card. The phone does not recognise JAD files. I can use the JAR file fine but it isn't fully functional.
3. Installing the JAD file from a WAP service by pointing my phones web browser directly to the JAD file online. It downloads and installs, but again, fails to be fully functional.
So at the moment I am stuck as although I can install the JAR by itself, the application is then not signed, and will not work because it cannot access the memory card.
Basically, how would I install a signed application (JAD & JAR) onto my Series 40 handset?

Since my last post I have been discussing this issue with commercial application developers and have been experimenting with various applications.
Firstly, let's make the JAR/JAD situation absolutely clear. Some, but not all, applications unquestionably require the JAD file as a part of the installation process. If the application is a "signed" application then the security authorisation is contained within the JAD file, not the JAR file. The JAD file is created from the JAR file and contains security verification information that is separate from the JAR file and which enables the application to signed as kosher.
The Nokia PC Suite Application Installer does not need to show you the JAD file. The JAR file is sufficient. If you install the application from a folder on your PC that contains both the matching JAR and JAD files then Application Installer will correctly install the application from both the JAR and JAD files. If the folder ONLY contains the JAR file then it will only install from the JAR file. I have proved this.
So, if you cannot get the application to work then the reason is not the installation process. The reason is far more likely to be that you are trying to install the application on a branded handset rather than on a standard Nokia handset. Some service providers heavily modify the base standard software that Nokia installs on its vanilla handsets and these modifications may well include changes to security authorisation rules that will prevent many applications working on handsets that they sell.
I am in dispute with one such as we speak. I will not name them right now but if I am unable to achieve a satisfactory outcome then be assured I will let EVERYONE know. Thank God for YouTube.

How to make file associations in my java apps

I am making a Graph maker in Java. Just give x = 1,2,3,4,5 and corresponding y = f(x) and get the discreate graph.
The graph can then be saved as a file of extention .grf (say) on the hard disk, and can be opened in my graph maker software for editing, viewing e.t.c.
Now my problem is that I want that when I dubble click on a file xyz.grf my graph maker should open automatically with this file opened in it, like other applications on windows say Notepad - dubble click on xyz.txt it will automatically launch Notepade with this file.
In other way I want that any .grf file gets associated to my graf maker.
Please help me and tell me the way, how should I proceed and how can I do this.

But now I want some thing more,(hand to forehead) They always want more. ;)
(a) There is a splash screen in my app. but JNLP always show its own splash screen, ...Webstart splash screens work differently to those of plain Jar files (which is unfortunate). A webstart splash screen has to be not included in the Jar, but available as a separate resource. The splash is defined in the JNLP launch file. For further details see the [JNLP File Syntax|http://java.sun.com/j2se/1.4.2/docs/guide/jws/developersguide/syntax.html].
<quote>
The optional kind="splash" attribute may be used in an icon element to indicate that the image is to be used as a "splash" screen during the launch of an application. If the JNLP file does not contain an icon element with a kind="splash" attribute, but does contain another icon tag, Java Web Start will display a splash screen consisting of the image specified by the icon element on the left and the application's title and vendor on the right.
The first time an application is launched following the addition or modification of the icon element in the JNLP file, the old splash image will still be displayed. The new splash image will appear on the second and subsequent launches of the application.
</quote>
The 'ignored first time' is because the webstart client is more focused on getting the app. downloaded, cached and launched, than showing splashes. Once the app. is on-screen, it will download the splash in the background.
One other 'gotcha' of splash screens is that the JNLP file must define a href in the JNLP element for the splash to be used. The webstart client assumes that a JNLP with no href is dynamically generated, and will not be the same twice. Because of that it ignores the splash!
Edit 1:
Unfortunately, I do not have any direct examples of using splash screens A splash is usually on my 'To Do' list for projects, but it is a very low priority.

Rashmi,
Following observations from the error log:
a) DC temp/jxljar1 is External Library DC; if I am not wrong.
b) Once the J2EE DC is deployed; automatically jxljar1 should also be loaded in server
Coming to the issue you are facing; plz let us know following points:
a) Are you trying to transport the content from one landscape to the other i.e. development to QA?
b) During what operation and in which unit(DTR/CMS/CBS);you are facing the issue?

Using loadjava utility to load a 3rd party jar file

Hi Folks,
    I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
    In order to connect to SQLite I'm using the the jar file sqlite-jdbc-3.7.2.jar that I got from https://bitbucket.org/xerial/sqlite-jdbc/downloads
    Then I tried to load the jar file into Oracle Database using the command:
    loadjava -resolve -user system/xpto@tm014_23 -schema novacap sqlite-jdbc-3.7.2.jar
    The result is a series of error messages with the error code ORA-29533.
    Ex: - Attempt to overwrite class or resource org/sqlite/Codes while defining or compiling SYSTEM.org/sqlite/Codes
    Can you guys help me?
Thanks,
Luis

I need to validate if a java class, stored into an Oracle Database, is able to connect to a SQLite database.
You need to explain that a little more.
How could a java class within Oracle connect to a SQLLite database if the driver it needs isn't already loaded into Oracle.
The fact that you have to load the driver jar file tells you that the class will not be able to connect to SQLLite.
The recommended way to develop with 'Java in the database' is to first write and test the code OUTSIDE the database. Then when it works load it in the databse.
So use a copy of the Java class and test it outside the database to see if it can connect.
Also since 11g you could just load that jar as a 'database resident' jar file. If you don't do that then Oracle just extracts all of the files in the jar and tries to load them one at a time. So using 'resolve' won't work because Oracle isn't going to load the classes in the proper order.
See 'database resident jars' in the Java Dev Guide
http://docs.oracle.com/cd/B28359_01/java.111/b31225/chtwo.htm#BEJCBAHI
Database Resident JARs
Starting with 11g release 1 (11.1), when you load the contents of a JAR into the database, you have the option of creating a database object representing the JAR itself. In this way, you can retain an association between this JAR object and the class, resource, and source objects loaded from the JAR. This enables you to:
Use signed JARs and JAR namespace segregation in the same way as you use them in standard JVM.
Manage the classes that you have derived from a JAR while loading it into the database as a single unit. This helps you to prevent individual redefinition of the classes loaded from the JAR. It also enables you to drop the whole set of classes loaded from the JAR, irrespective of the contents or the continued existence of the JAR on the external file system, at the time of dropping it.
In order to load a JAR into the database, you have the following options of the loadjava tool:
-jarsasdbobjects
-prependjarnames
For more information regarding the loadjava tool options, refer to "The loadjava Tool" section.
