Subject: double clicking on Netware

Hi,

I saw your problem (on Info-Mac) about double clicking files and not being
able to launch application on the server.

We have had that problem on some of our macs.  Not all of them though.  I
recently got the latest NetWare client files for the Mac.  On the disk is a
file called Extension Mapper.  I read the ReadMe file on the disk.  Here is
what it says:

( I appologize, this is long.  But I thought all of it would be of interest
to you).


Extension Mapper 1.0 Read Me 

NOTE: The Extension Mapper application works only with NetWare servers
running NetWare for Macintosh 4.0. 
 

== About Extension Mapping ==

Extension mapping associates Macintoshr application information with filename
extensions. The Extension Mapper utility on the Macintosh allows a user to
create and configure his or her own lists of mappings. The same file can be
associated with different icons; users can therefore double-click an icon for
the same file and launch different applications. For example, one Macintosh
user can view a file created with WordPerfectr on a DOS PC as a Microsoft
Wordr file, while another can view it as a MacWriter file.

When using the Extension Mapper, keep these points in mind:

* Extension mapping does not alter the contents or formatting of a file. The
application associated with the file must understand the format of the file
being launched.
  
* Both DOS and Macintosh files are mapped. In the case of a Macintosh file,
the existing Type and Creator is overridden in the Finder TO THE TYPE AND
CREATOR OF THE MAPPING.
 
* Extension mapping does not alter DOS files in any way. However, extension
mapping may cause Macintosh files to have their Type and Creator permanently
changed by the Finderx, or by writing the file.

* The Extension Mapper application provides predefined default extension
mappings. These defaults are listed in the section "Default Extension
Mappings," below. If you double-click a file and the default application
associated with the file is unavailable, the Finder informs you that the
application that created the file cannot be found.

* For the Extension Mapper to work with files stored on server volumes, you
must enable extension mapping at the server with the AFPCON utility. If you
start the utility before extension mapping is turned on at the server, you
must exit the application and restart it in order to see the mappings.
 
* A file named MY.DOCUMENT in the Macintosh name space will have the name
MY.DOC in the DOS name space. As a result, the Extension Mapper interprets
the filename extension as .DOC and maps the filename to the application
associated with the .DOC filename extension. So, you should keep in mind that
a file renamed for the DOS name space may have unexpected mappings.


== Default Extension Mappings ==

These are the default applications and file types associated with each
filename extension:

.XLW: Microsoft Excel 3.0 Template file


== Using Different Versions of the Same Application ==

Different versions of the same application may support different file types.
For example, older versions of TeachText do not support the PICT file type,
but newer versions do. If different versions of the same application exist on
any mounted volume, including a hard drive, SCSI volume, NetWare volume, or
AppleSharer volume, the Extension Mapper looks for the file type associated
with the first version of the application it finds. This situation may cause
confusion if the user creates a mapping to a file type not supported by that
version of the application. For example, if the user creates a mapping
between TeachText and the file type PICT, and the version of TeachText found
does not support this file type, the utility informs the user that no file
type PICT exists. 

To solve this problem, try not to keep different versions of the same
application on your system. Or, you can keep the correct version on a volume
that the Finder searches first. The Finder searches the startup volume first,
and then searches the mounted volumes in the order in which you mounted them.
For example, suppose Excel 3.0 exists on a SCSI drive, and that filename
extension .XYZ is mapped to Excel 4.0, located on the startup volume. When a
user double-clicks a file with the .XYZ extension, Excel 4.0 is launched. 


== Changing Extension Mappings ==

If you change an existing extension mapping, you may need to refresh the
Finder before the change becomes active. For example, if the extension .XYZ
is mapped to Microsoft Word and you want to map the extension to WordPerfect
instead, you may need to refresh the Finder and possibly wait a few minutes
before the proper icon appears. To refresh the Finder, either log out of the
NetWare 4.0 server, or quit the Finder. To quit the Finder under System 7.x,
press Control+Option+Command and then press Esc. Be aware, however, that if
you quit the Finder you will disconnect from other services you may be using.


If the server is using the Finder Accelerator Cache, you may need to wait for
the cache entry for your particular folder to age and be refreshed. The time
this operation takes can vary according to usage of the system and the
percentage of free memory allocated to the cache, but it will usually be
negligible. You can also disable the cache at the server by using AFPCON.   

Tip: Closing and reopening the folder window is usually sufficient to refresh
both the Finder and the Finder Accelerator Cache.

=============================
You may be able to find the new client files at Novell's FTP site.  If not, I
can send you the Extension Mapper in BinHex format via e-mail.

Hope all this helps.
