I'm seeing issues when trying to do a "Run" or "Run As". I went
through the HelloWorld tutorial to make sure I'm not missing anything,
and at the end of the tutorial when it says:
To run your application, right-click on your class in the Package
Explorer and select Run As > Java Application. The Console view should
appear at the bottom and display the "Hello, world!" output.
There is only "Open Run Dialog..." when I right click on the class and
hover on "Run As". If I go through and add a configuration under "Java
Application" (and add HelloWorld as the class) or just click the run
button on the toolbar and choose "Java Application", I get the following
error:
Exception in thread "main" java.lang.NoSuchMethodError: main
Error: A JNI error has occurred, please check your installation and try
again
What am I missing?
Timothy,
It appears you do not have a proper main method. You should have the
following method in your HelloWorld.java file:
public static void main(String[] args) {
System.out.println("Hello World!");
}
You would have gotten this when you created your New Class if you asked
it to create your main method (there is a click box).
If you right-click on the java file, you will be offered the option to
run it as a Java Application. If you rename it to main2, for example,
you will instead see "Open Run Dialog" offered. If you try and force
this to be run via the dialog, you will get the error message you are
seeing which is entirely expected.

/ NEW YORK-- Kraft Foods, Inc. announced today that its board of \
| directors unanimously rejected the $11 billion takeover bid by Philip |
| Morris and Co. A Kraft spokesman stated in a press conference that the |
| offer was rejected because the $90-per-share bid did not reflect the |
| true value of the company. |
| Wall Street insiders, however, tell quite a different story. |
| Apparently, the Kraft board of directors had all but signed the takeover |
| agreement when they learned of Philip Morris' marketing plans for one of |
| their major Middle East subsidiaries. To a person, the board voted to |
| reject the bid when they discovered that the tobacco giant intended to |
\ reorganize Israeli Cheddar, Ltd., and name the new company Cheeses of Nazareth. /
