MakeJar Script for Client JAR Files
JAR Files and Security
Included with Windchill is a MakeJar script that contains the ant task for creating
client JAR files.
From a windchill shell, enter the following command to update the contents of all
client JAR files:
ant -f MakeJar.xml
The JAR class loaders of the bootstrap package guarantee that classes loaded from
cached JAR files are subject to the same security policies as if they were
downloaded from the remote codebase by the normal applet class loader. This is
usually a policy assigned to unsigned code or one associated with the remote
codebase (site).
The local JAR file is merely a substitute for the remote codebase, so that all class
and resources loaded by the class loader can be retrieved quickly without
accessing the remote codebase. In all other respects, including security policies,
behavior is identical to loading from the network. There is no benefit to having
signed classes in the cached codebase JAR file because the classes are treated as if
they were loaded over the network. (This would be the case for users without the
bootstrap loader or a local file that was being ignored).
