Hello All,

I am using NetBeans4.1 to build a simple application to use at my home.

The problem with Java programs ( i used eclipse before too) is that the IDE doesnt provide an exuctable file in the end which really annoys me

I am sure there is a way to make an executable file, but how can this be done ??

Thanx in advance

Jar files are executable if you have java virtual machine is installed. At least you can do a batch file or script which acts like executable, that contains like

java -xvj <name>.jar

Dont remember (xvj) switches exactly it may be different

I didnt fully understand the last part

hwo to combine all the resulting .java files to that JAR file ?

http://java.sun.com/docs/books/tutorial/jar/basics/

simply

To create a JAR file
jar cf jar-file input-file(s)

To view the contents of a JAR file
jar tf jar-file

To extract the contents of a JAR file
jar xf jar-file

To extract specific files from a JAR file
jar xf jar-file archived-file(s)

To run an application packaged as a JAR file (requires the Main-class manifest header)
java -jar app.jar

To invoke an applet packaged as a JAR file
<applet code=AppletClassName.class
archive="JarFileName.jar"
width=width height=height>
</applet>

OK, I managed to make the JAR file but my problem now is with executing it, I read that i must edit the mainfest file to mention the Main class

now my main class is called firstWindow (in a .Java file), and there is another file called firstWindow.frame

so which of them should be considered as the Main class ? and how to edit the manifest file to mention that this is the main class ??

thanx in advance

It should be automatic when creating. After creating jar file you should simply run it by

java -jar app.jar (assuming you have jvm installed)

If you couldnt then what was the error you get?

Or just use NetBeans to create the jar file and manifest.
You can then test it in NetBeans plus edit files and update the jar file plus it's manifest easily.

Just follow sadun's instructions run outside of NetBeans.

here is the error I get

Failed to load Main-Class manifest attribute from
john.jar

prj,

how to do that from NetBeans ?

"Just" create new jar. Use wizard to specify various properties.
Drag all the files into it. Highlight jar in file tree. Compile (F9)
Voila!

You can edit the jar by right clicking on it and changing all sorts of properties.

Ok, I managed to do it from the NetBeans

but i still dont get how to create a new JAR file ??

all i had to do is to right click on the project name on the left and choose build

then the jar file appeared in /dist directory, but it didnt appear in the project tree in the IDE

but another problem arrised, my application is a DB application, when I run it from the jar file it doesnt work with the DB at all, ie when I submit any data or try to retrieve from the DB nothing at all happens !!!!!!!!!!!!!

the DB is with mysql

here is what i get when i try to communicate with the DB

so any suggestions ?

Oops, sorry thats me going back to NB 3.*.
To make changes in 4.1 right click on the project and choose properties.
Then check the nodes shown for various properties.
3.* used to be lovely for this!

For your db its possible but I'm not 100% that you may need to add some library (JDBC?) to your jar, again from the project properties dialogue.
Although I thought you could choose a connection, assuming you've created one, from the runtime listing?

thanx alot

It was an issue of adding the mysql jdbc connector in the JAR file
