JRE's prior to 1.4.2_01 were less restrictive with respect to JavaScript > Java communication, therefore the Java Viewer functiond without explicit security changes. As a result, permissions granted for the applet codebase in the java.policy file, as a default found at $JAVA_HOME/lib/security, are not honored in a JavaScript > Java call.
#Jre 1.4.2 code#
Since the origin of JavaScript code cannot be verified, Java code called from the JavaScript is not considered to be from the same codebase. With JRE 1.4.2_01 and later versions, Sun introduced new security restrictions for JavaScript > Java calls. : :Īccess denied( modifyThreadGroup)Īt .(Unknown Source)Īt .IMSMap.enableFunction(Unknown Source)Īt (Unknown Source) : access denied ( modifyThreadGroup)Īt (Unknown Source)Īt (Unknown Source)Īt (Unknown Source)Īt (Unknown Source)Īt (Unknown Source)Īt .(Unknown Source)Īt .(Unknown Source)Īt .ui.(Unknown Source)Īt .ui.(Unknown Source)Īt .IMSOverviewMap.redraw(Unknown Source)Īt 0(Native Method)Īt (Unknown Source)Īt (Unknown Source)Īt .invoke(Unknown Source)Īt .invoke(Unknown Source)Īt .invokeImpl(Unknown Source)Īt $2.run(Unknown Source)Īt (Native Method)Īt .invoke(Unknown Source) Verify one of the following errors appears in the Java Console: The Java Console should start in a separate dialog window.Ħ.

Otherwise, the user should see either a shared library error If the output from the command is "Hello World!!", BBjServices should run. In BBj 6.0 a utility was added to verify that a 1.4.X JVM could be run

This corrects the "NoClassDefFoundError" described above.Ģ) The security problem may be resolved by either of the following methods.Ī) The SE Linux security can be disabled.ī) Install the "selinux-policy-targeted-1.25.2-4.noarch" package.
