Trusted-Only AttributeTrusted-Only attribute should be used. No warning dialog will be displayed and an application or applet that loads a jar file containing this attribute will not load any untrusted classes or resources. This attribute prevents a signed application or applet from being re-purposed with unsigned components. You can specify Trusted-Only: true in the manifest file. For example:Manifest-Version: 1.0 Trusted-Only: true Created-By: 1.6.0-internal (Sun Microsystems Inc.)
Trusted-Library AttributeTrusted-Library attribute should be used. No warning dialog will be displayed and an application or applet may load jar files containing untrusted classes or resources. This attribute prevents signed components in an application or applet from being re-purposed with unsigned components. You can specify Trusted-Library: true in the manifest file. For example:Manifest-Version: 1.0 Trusted-Library: true Created-By: 1.6.0-internal (Sun Microsystems Inc.)
Trusted-Only: true or Trusted-Library: truejar cfm jar-file manifest-addition input-file(s)
