webstartservices.installer
Class RuntimeInstaller  

java.lang.Object
  webstartservices.installer.RuntimeInstaller

---

public class RuntimeInstaller

extends java.lang.Object

RuntimeInstaller - This installer starts running before downloading the actual runtime package from our server across http; rather like iesetup. The address of the runtime to download from is supplied by the runtime.url parameter; this in turn was supplied via a RuntimeMapper choice from DownloadService. Advantages over JREInstaller include a quicker popup, the downloaded runtime is stored as a temp file which should automatically get deleted after use (rather than stoge up the users WebStart cache). The runtime dosnt need copying after downloading before we can access it, nor does it need double jar'ing. An unintenional side-effect is that this jar won't need signing; maybe I should revise this issue for security sake). If it has been signed it must be valid or SecurityExceptions will be thrown.

locateRuntime_Win32

protected java.io.File locateRuntime_Win32(java.lang.String version)

Locate the runtime location for the given java vm version. Should work for most default installs -- but isnt a robust solution; certain method would require windows registry access via JNI.
