#58 JWebBrowser Applets in JAVA 7

[Rodney]

Java Applets are ignored in JWebBrowser running JAVA 7. Running with JAVA 6 is successful.

System: Windows 7 x64
Java x86: JDK 1.7.0_05 and JDK 1.6.0_33

java -version:1.6 -jar DJNativeSwing-SWTDemo.jar
java -version:1.7 -jar DJNativeSwing-SWTDemo.jar

Tested using the Simple Example JWebBrowser from the demo. The Applets run fine when loaded directly in IE9.

Hi,

Applet support requires a certain number of conditions at the SWT level. DJ Native Swing sets up some of the required conditions (like classpaths) but some external conditions are still applicable:
http://www.eclipse.org/swt/faq.php#browserapplets

Things like "the Next Generation Java Plug-in enabled" or "The application is launched with the same JRE that provides the installed Java plug-in" may not be respected?

[Rodney]

I have verified the Java Plug-in is enabled and the same JRE is used.

I noticed when it is ran in 1.7 that the XbootClasspath is not set.

When I run the Demo through the JNLP, it uses java 1.7 and the java console displays the following stacktrace:
