Siebel thin client cab (class/jar) files

Hi,

We have a very high security operating system environment for our clients using thin client to access Siebel. We used to run predeploy to acquire the needed ActiveX control files for the clients and then create an msi for a silent install. However the problem with that was that some controls were left out so instead we're using the public directory to substract files from there. It has some cab files containing .class and .jar files. Our guess is that these by no means are necessary for the client, since these don't ever get exported using predeploy command. Can anyone
