Can you please upload a sample test case?

I have attached a tar with a sample project.
You will find a README.txt at the root, after untar.
It contains further instructions to launch the rcp application. Let me know, If 
anything is missing.

Attached is a patch that can be applied in the javacef directory. I will commit 
it after I test it on other platforms. The main reason is that rcp uses osgi 
class loader rather than the default class loader, and it couldn't find 
"org.embedded.browser.Chromium" when FindClass() is called in jni. This patch 
saves a reference of the class so it does not need to find it again. I think 
your code might still work without this patch if you can set up class path and 
plugins correctly.

Thanks a lot!.

The patch works. I have not verified the other approach you have suggested 
(fixing the classpath)

Thank you once again.

Looks like, there are multiple points, where such class-lookup fixes have to be 
made.

@ShiQuan1128, are you using Windows CEF 1750? Maybe the fix in 
https://code.google.com/p/javacef/source/browse/cef3/java/src/org/embedded/brows
er/ChromeWindow.java#44 is not enough. Can you try the 3.1547 branch?
