When I make my desktop Java clients, I copy the entire lib folder that I use for compiling to the same location as my jar file (so that I see the lib folder there and all the jars are in it except the project jar. Try that.

Does the client work when run inside Eclipse?

Does the client use loadAndConnect? If so then it needs to have the settings.xml file where it can find it.

If you double-click on the jar for the Java client for SimpleChat (ElectroServer_5_3_3\code_examples\SimpleChat\clie nt\java\bin\SimpleChat.jar), does that work? If not then you need to tell your operating system that the .jar extension needs to be associated with "Java Platform SE Binary".

I've made quite a few Java desktop apps, but I used NetBeans.

Rereading the original post, the bug is definitely that Java isn't finding the ES5 Java api jar.

I already built jar file by Netbean or using ant file. I run it on eclipse is okie. But using eclipse to buit it is error. Thank you so much!

If I understand you correctly, your project works just fine if you build using NetBeans or using Ant. It runs from inside Eclipse just fine. Eclipse just doesn't build the correct jar for you that will work on your desktop.

If this is correct then the problem is with Eclipse or with the project settings in Eclipse, not with ES5. Googling turned up a suggestion on StackOverflow to check your Eclipse run configurations to see if something is set correctly in running from the IDE but not in running outside the IDE.

That's about all I can help you with on this, since it's not an ES5 issue and since you already have two workarounds available (using NetBeans, using Ant).
