A class to access disk resident application downloads for the Gateway 50. All binaries seen so far have two version strings at a fixed offset near the beginning. We compare these for a sanity check.

Summary  |  Top

   public GatewayApp(String fn)  throws IOException

Create a reference to a disk resident Gateway application binary.

Parameter	Description
fn	the filename of the binary

   public String getVersion()  throws IOException

Return the version string for this Gateway Application download.

   public String getPath() 

Return the pathname of the application binary.

   public int getXID()  throws IOException

Return the current XID for this Gateway Application download. Support inspecting the SNA XID hard coded into a Gateway 50 application download. This ought to be a configuration option, but it isn't. We select the XID offset based on the version string. The XID is stored twice with different prefixes, so we can sanity check it.

   public void setXID(int xid)  throws IOException

Set the XID for this Gateway Application download. Support changing the SNA XID hard coded into a Gateway 50 application download. This ought to be a configuration option, but it isn't. Until it is, this utility helps in patching the binaries.

Parameter	Description
xid	the new XID

   public static void main(String[] argv)  throws Exception

Command line interface.

Usage: java bmsi.sna.GatewayApp [-xXID] file1 [file2 ...]
	Reports the App ver and current XID for each listed file.
	-xXID	changes the XID of following files,
		XID is a hexadecimal number
