Wiki Page: java.lang.SecurityException: Missing required Permissions manifest attribute in main jar:

With java 7 update_51 web to host sessions receive a SecurityException Errror. Web to host up to version 6.5 have been tested up to version 7 Update_29. Version 6.6 will work with Jva update_51. The workaround for older version of Web to Host to work with the latest Java 7 updates will be to put the url in the secure zone of the java client.
