In WebInstance.zip, we have included a .txt file with the instructions to install it on WebCenter.
If you have any doubts on the installation of this patch after reading the included instructions, please contact Esko Customer Support.
What happens if you don’t use the patch?
On WebCenter (12.0) you won’t be able to open the collada viewer and the workflow applet. The reason of this problem is the new Java version (version 7 update 21) which affect PC and Mac. If you try to open this features without this patch you will see the following error message: "Error in building: access denied ("java.lang.RuntimePermission" "accessClassInPackage.com.sun.org.apache.xerces.internal.jaxp")"
For Lion and Mountain Lion, Chrome no longer supports Java applets on Mac 10.7 & 10.8. For more information about the collada viewer, see (from esko.com):
