creating executable jar [message #465968]

Hi,

I am trying to create an executable jar from my SWT project. In Eclipse
I exported the project and created the jar file. I also created
directory lib and put three jars in there:
org.eclipse.core.runtime_3.1.0.v20051027.jar, rg.eclipse.jface_3.2.0.jar
and swt.jar.

My MANIFEST.MF file looks like this:

Manifest-Version: 1.0
Main-Class: com.kwi.gui.WidgetWindow
Class-Path: ./lib/org.eclipse.core.runtime_3.1.0.v20051027
../lib/org.eclipse.jface_3.2.0 ./lib/swt.jar

------------------------------------------------------------ -------------------------------------------

and .classpath:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
<classpathentry kind="src" path=""/>
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
<classpathentry sourcepath="./lib/org.eclipse.jface_3.2.0.jar"
kind="lib" path="./lib/org.eclipse.jface_3.2.0.jar"/>
<classpathentry kind="lib"
path=./lib/org.eclipse.core.runtime_3.1.0.v20051027.jar"/>
<classpathentry kind="lib" path="./lib/org.eclipse.swt/swt.jar"/>
<classpathentry kind="output" path=""/>
</classpath>

However, if I double-click on application jar, I get error: "Could not
find the main class", but if I execute the jar on command line I get
different error:

Exception in thread "main" java.lang.NoClassDefFoundError:
org/eclipse/jface/window/ApplicationWindow

Which I guess means that it can't find external jars that I am including
where ApplicationWindow class lives.

And finally this is my folder structure:

clientSQL
|
------ com
|
------ lib
|
------ .classpath
|
------ .settings
|
------ .project
|
------ clientSQL.jar
|
------ MANIFEST.MF
|
------ swt-awt-win32-3139.dll
|
------ swt-win32-3139.dll

Also, one more dumb question. If I describe all my jar dependencies in
MANIFEST.MF file, what's the function of .classpath file?

Any help is greatly appreciated.

thanks!
Alex
