Marytts export voice to executable jar

I am currently trying to use marytts in my project. Now I am trying to export my project to an executable jar file. The problem is I always get this error:
java.lang.IllegalArgumentException: No such voice: bits3-hsmm
In IntelliJ everything works fine, the error only occurs when executing the exported jar file. I added the dependencies as shown in this photo
The marytts interface is working correctly only the voice makes troubles. A am using an downloaded version of the voice and marytts and they should be included in my exported .jar file.

This looks like a product of IDEA-240253 (and related IDEA-116209).
IDE should be able to handle this automatically, but currently it isn't implemented.
You may keep separate JAR files and add them to the classpath of your JAR via Class-Path attribute in MANIFEST.MF file.

Exported Jar file throws exception (JDBC)

I have made use of JDBC in one of my projects and it worked flawlessly in Eclipse. I had to add the ojdbc6.jar to Java Build Path to the project BTW. (I have also not included any Class.forName statements in the code since I heard it's optional for JDBC 4 and above)
When I export the project into a jar file, and try to run it, it complains saying "No driver found for JDBC" and so on. I can see that this is because the ojdbc6.jar is missing from the build path now. Can someone please let me know of a solution?
Thanks!

Here is a simple method to export a JAR that uses external jar as libs:
You have to write a manifest file, I named it jar.manifest.
The content in manifest file looks like:
Manifest-Version:1.0
Main-Class:com.enginebai.activity.MyJDBCProgram
Class-Path:lib/ojdbc6.jar lib/some-externam-lib.jar
and make sure to put a blank line under Class-Path, otherwise the JAR won't run. (I have no idea why to put a blank line over there.)
Let's go back to eclipse:
In eclipse, you export your classes and remember to select above manifest file.
Make sure your ojdbc6.jar be in project/lib folder.
Open your terminal and cd to project root directory, enter `java -jar your-jar-name.jar', it should work then.

put ojdbc6.jar on classpath when you run your jar

I have done some research and found a solution that seems to work.
I have exported the project into a "Runnable Jar file" instead of just a "jar file".
This way, I was actually able to repack Jar files from my Build Path into the new Jar file I am exporting my project to. Simple and clean.
You also might want to look at signed Jar files and any other certificates in your existing jar files in the Build Path. They cannot directly be repacked through the export option.

Generate Executable Jar file in LIBGDX

To be clear, i know there is a thread like this on stackoverflow and he uses eclipse while I use Intellij. Creating an executable jar in eclipse and intellij are different. So before downvote kindly consider my scenario. I created a simple java game using libgdx and want to export it in an executable jar. But before doing so, I experimented in creating a jar of the one in the tutorial video of official LIBGDX.This is the jar file Dload it here.. If you execute it opens then close again. But when i ran the project in intellij it runs without error.
This is the image i was expecting if i execute the jar file i created..
What is wrong when i tried to create a jar file?? Anyone?? Thanks

Just open your exported jar file like a zip archive and export your assets folder and libraries beside your jar file then test it again. Hope this helps.

creating and running jar file with source

I write a very simple java program with two classes: Business and Main.
I want to create a jar such that if I email it to someone they can:
run the program (i.e. run the jar)
open the jar to view the source code.
the code can run on mac or windows
I have been using IDEs for so long I have forgotten how to do this.
I am using netbeans 7.x
EDIT:
I found the following way on Netbeans:
properties > packaging > exclude from jar file :: delete **/*.java
But when I try to execute the jar using
java -jar mybusiness.jar
it says
no main manifest attribute, in mybusiness.jar
But note that my jar has a main class. Am I missing a manifest file?

You can export a JAR file that includes the source code using Netbeans:
Right click on the project and select properties
Build -> Packaging
Remove Java files from the excluded files. And select build jar after compiling
It will create the jar file that includes the source code if it successfully compiles.

Well surely an IDE can do this too?. Just make some text files and put the source into them and drag them into the ide's. It's java so it should automatically run on all platforms. I am not sure what the problem is here?

This link explains how do u create manifest file and how do you specify your main class in manifest file as its necessary for executing jar.

Making excutable jar file using eclipse

My project runs fine from Eclipse.
But when I tried to make it into a jar file or executable file it doesn't work.
I used the option "Export-Runnable JAR file"
The following message appears just after the eclipse finished the exporting process
JAR export finished with wornings , see details.
the details were ..
Exported with compile warnings:Mario/src/Map.java
and the same for other classes like
Exported with compile warnings:Mario/src/Player.java
and so on.
So that I used the other option "Export - JAR file"
It works fine and nothing appears while exporting it from Eclipse.
But when I try to open the file it gives me
Couldn't find the main class:Frame.Program will exit
Somebody have any idea about what the problem is?

Your MANIFEST.MF file inside the META-INF dir should have a Main-Class attribute pointing to your main class.

The important thing for executable jar is Manifest. Make sure it exists and points to the correct class with main method
