Error with Java certificate

Do you got this error:
"Caused by: net.sourceforge.jnlp.LaunchException: Fatal: Application Error: Cannot grant permissions to unsigned jars."

and also like this:
net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize application. at net.sourceforge.jnlp.Launcher.createApplication(Launcher.java:644) at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:418) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:725) Caused by: net.sourceforge.jnlp.LaunchException: Fatal: Application Error: Cannot grant permissions to unsigned jars. at net.sourceforge.jnlp.runtime.JNLPClassLoader.setSecurity(JNLPClassLoader.java:216) at net.sourceforge.jnlp.runtime.JNLPClassLoader.(JNLPClassLoader.java:170) at net.sourceforge.jnlp.runtime.JNLPClassLoader.getInstance(JNLPClassLoader.java:249) at net.sourceforge.jnlp.Launcher.createApplication(Launcher.java:634) ... 2 more Caused by: net.sourceforge.jnlp.LaunchException: Fatal: Application Error: Cannot grant permissions to unsigned jars. at net.sourceforge.jnlp.runtime.JNLPClassLoader.setSecurity(JNLPClassLoader.java:216) at net.sourceforge.jnlp.runtime.JNLPClassLoader.(JNLPClassLoader.java:170) at net.sourceforge.jnlp.runtime.JNLPClassLoader.getInstance(JNLPClassLoader.java:249) at net.sourceforge.jnlp.Launcher.createApplication(Launcher.java:634) at net.sourceforge.jnlp.Launcher.launchApplication(Launcher.java:418) at net.sourceforge.jnlp.Launcher$TgThread.run(Launcher.java:725)


If you are using Ubuntu, than you have to upgrade your Java to "sun-java6-jdk".

root@saktilubis:~# aptitude install sun-java6-jdk
