How Do I Publish My Working Project (corresponding dot jar doesn'twork on other's PCs)
 

Hello,

Once my NetBeans project is finalized what do I have to do to create an executable others can execute without having NetBeans directly installed on the computer.

Currently, my project contains a dot jav file which I can run to execute myproject. But, when others try to execute that same dot jar it doesn't work.. (Am I missing something here or should executing the dot jar always work.How should I troubleshoot this problem.)

Thank you,

Maybe a trivial question, but do they have Java installed?

(I mean, they shouldn't need netbeans, but they will need
at least a Java Runtime Environment (jre) to run jar files.)

Java Web Start appears to address this on supported platforms in the
href provided to the version attribute of the j2se tag. I've never
actually tried it, as my platform vendor supplies the JRE.

What type of project did you create in NetBeans? Was it a Java
Application? Only this type of project creates the necessary manifest in
the project jar for it to be run simply by the java -jar project.jar
command. There are also some other constraints which if they are not met
will cause NetBeans to not create an "executable" jar. Offhand I cannot
remember what they are, and I've not had this problem re-occur for some
time.

A NetBeans Java Application should create a dist/ directory containing
the actual project jar, and a dist/lib directory containing any required
additional jars. It should also include an appropriate manifest in the
project jar which makes the jar "executable" (i.e. has a Main-Class
property). It also includes the lib/ directory in the jar Classpath.

Check the contents of your dist/ directory, and the project jar. If it
doesn't include these features then it's not a proper Java "application"
jar. That may mean that you didn't create it correctly, or NetBeans has
cocked up (technical term) the project properties (this does happen). If
this does happen the simplest alternative is to create a new Java
Application project and copy all your sources into it. Fixing it
manually requires dexterous manipulation of, IIRC, project.properties
and build-impl.xml. Creating a new project is simpler, quicker, and less
likely to bite you back in the future.

Not exactly. You can certainly edit the manifest in a normal JAR project or
normal Java project. I haven't worked with the "Java Application" NetBeans
project, but I've seen some complaints about it in this forum. Just set
"Main-Class:"

Read the Oracle site docs about JARs and JAR manifests. Your customers
can run JARs via Java WebStart, as mentioned, or directly by associating
"java -jar" with JAR files (might need "javaw -jar" on Windows platforms).

The manifest's "Class-Path:" header, which specifies paths relative
to the JAR location on the target system.

You don't need to futz with NB-specific files if you edit manifests yourself,
and also you should build from "build.xml", not IDE-specific artifacts.

I like the flexibility NetBeans affords in this area:

For convenience, I can use the stock, NB-generated build.xml, even from
the command line, and hook into it as needed:

<http://stackoverflow.com/q/3955299/230513>

Alternatively, I can add a small number of targets to my custom
build.xml, and NB will happily adopt it in a free-form project:

You can bundle it up into a jar.

You can compile the Java with jet to an exe

Help, all I need is:

(1) the JDK (which one, The jars were created with NetBeans 7.1.2),

(2) put /dist/lib/*.jars" into my classpath environment variable, and

(3) possibly use "java -jar" and "javaw -jar"?

Thank you,

That depends on how you have NetBeans and the particular project
configured.

Which JDK did you configure the project to use?

> (2) put /dist/lib/*.jars" into my classpath environment variable, and

What? Huh?

You shouldn't be messing around with root-level
directories like that.

Put your project directory under your home directory or
in some suitable location like /projects/.

> (3) possibly use "java -jar" and "javaw -jar"?

What do you mean?

The "-jar" parameter to those commands specifies a JAR
file for Java to run, if that's what you're asking.

On NetBeans, how do I determine what JDK I'm using. I forgot which one I loaded.

Thanks,
