edit-on Pro Technical FAQ
|
3.16 Since Java Update 1.6_19 I get a Security Warning when starting edit-on Pro.
After installing Java 1.6 Update 19, a warning dialog (see below) is displayed when starting edit-on Pro which might cause end user confusion. This dialog appears even though edit-on Pro only contains signed code and no unsigned code (thus it does not contain mixed code). This behavior is a bug in the Sun Java VM which has been fixed in Java 1.6 Update 20, see: http://java.sun.com/javase/6/webnotes/6u20.html. Therefore we recommend to update to Java 1.6 Update 20 as soon as possible.
Depending on your specific integration and configuration of edit-on Pro, the dialog may still appear after updating to Java 1.6 Update 20 in the following cases: 1) When loading a custom DTD that is not included a signed JAR file. 2) When loading a custom icon that is not included in a signed JAR file. 3) When loading a custom dialog that is not included in a signed JAR file. The dialog is no longer displayed in the first two cases as of edit-on Pro version 5.3.246.217. Starting with this version of edit-on Pro, custom Java classes (such as custom Java dialogs or custom Java clean-up classes) must be packaged in a JAR file. If custom Java classes are not packaged in a JAR file, they can not be loaded as they can no longer automatically be retrieved on demand from the code base. Furthermore, if Java version 1.6.0u19 or newer is used on the client system, the JAR file containing the classes should be digitally signed to prevent the Java "mixed code" warning dialog from being displayed. To prevent the warning dialog from being displayed when using custom dialogs, the dialog implementation and resources have to be packed in a JAR and digitally signed by you with a valid code signing certificate. Alternatively, to prevent this dialog from appearing, it is possible to deactivate the "Mixed Code Verification" feature in the Java preferences. To do so, open the Java Control Panel on the client computer, and select the "Enable - hide warning and run with protections" option in the "Security" category (see below).
For more information about the new "Mixed Code Verification" feature please visit the Java website at:http://java.sun.com/javase/6/docs/technotes/guides/jweb/mixed_code.html. |
