Symptom

The ICA Client for Java is always deployed for users connecting with a Safari Web browser.

See Page 83 of the Web Interface 3.0 Administrator’s Guide.
See Page 77 of the Web Interface 4.0 Administrator’s Guide.

Cause

This is by design, in order to maintain compatibility with Mac OS X ICA Clients prior to v7.00.407; Web Interface restricts users to only use the Java Client when connecting with Safari.

Workaround

This Workaround is in two parts.

Mac OS X ICA Client version 7.00.407 or above to be installed on the Client platform.

1. Changes are made to Web Interface to allow the native Mac OS X ICA Client to be used with Safari. (Note that there are separate workarounds for Web Interface 3.0 and Web Interface 4.0 on ASP and JSP platforms).

Workaround for Web Interface 3.0

The following applies to Web Interface 3.0 ONLY, for Web Interface 4.0 see the next section.

For IIS

1. To disable safari from defaulting to the ICA Client for Java, edit the Embed.cs file. This file is in the Metaframe/site/include/serverscripts directory on the IIS Web server.

2. Use Notepad to open the Embed.cs file and locate the following piece of code:

//Only allow applications to be launched with the Java client on Mac and Safari.

if (sClientInfo.osMac() && sClientInfo.isSafari()) {

validClient = "ica-java";

}

3. Change

validClient =“ica-java”

validClient=“ica-local”

4. Save the change.

5. After making this change, users are directed how to launch a connection through Web Interface.

6. To display the client install caption on Safari, edit line 80 of MetaFrame\site\include\messagecenter.inc, which reads:

if (!sClientInfo.osWinCE() && !sClientInfo.isSafari()) {

Change this line to:

if (!sClientInfo.osWinCE()) {

7. Save and close file.

On the JSP (Unix) Platform

1. Edit MetaFrame\serverscripts\include.js

2. Comment out or delete lines 841, 842 and 843, which are:

if (clientInfo.osMac() && clientInfo.isSafari()) {

validClient = "ica-java";

}

3. Save and close this file

4. To display the client install caption on Safari, edit line 82 of MetaFrame\include\messagecenter.inc, which reads:

if (!sClientInfo.osWinCE() && !sClientInfo.isSafari()) {

to read

if (!sClientInfo.osWinCE()) {

To Display the Client Selection part of the Settings Dialog

(Instructions apply to Windows & UNIX)

Edit line 331 of appsettings.inc (in the 'include' directory),

if (bShowClients && !(sClientInfo.osMac() && sClientInfo.isSafari())) {

to read

if (bShowClients) {

Workaround for Web Interface 4.0

The following applies to Web Interface 4.0 ONLY, for Web Interface 3.0 see the previous section.

For IIS

1. To allow the use of the native client with Safari, edit the file MetaFrame\site\serverscripts\include.cs , and locate the following section:

} else if (sClientInfo.isSafari() || autoFallbackToJICA()) {

2. Replace with:

} else if ( autoFallbackToJICA() ) {

3. Edit the file MetaFrame\site\serverscripts\embed.cs and comment out the following section by preceding each line with two forward-slashes ( // ).

if (sClientInfo.osMac() && sClientInfo.isSafari()) {

result = MPSClientType.JAVA;

}

4. To display the client install caption in the Message Center, edit MetaFrame\site\serverscripts\install.cs and locate the following section:

if ((! sClientInfo.osWinCE()) && (! sClientInfo.isSafari())

5. Replace with:

if ((! sClientInfo.osWinCE())

6. To display the client selection in the settings dialog, edit the file MetaFrame\site\serverscripts\appsettings.cs and locate the following section:

&& (! sClientInfo.isSafari()) && (! sClientInfo.osPocketPC());

7. Replace with:

&& (! sClientInfo.osPocketPC());

8. Also edit the file MetaFrame\site\serverscripts\clientsettings.cs and locate the following section:

&& (! sClientInfo.isSafari()) && (! sClientInfo.osPocketPC());

9. Replace with:

&& (! sClientInfo.osPocketPC());

For the JSP (Unix) Platform

1. Edit the file site/serverscripts/include.js and locate the following section:

} else if (sClientInfo.isSafari() || autoFallbackToJICA( request, response,

2. Replace with:

} else if (autoFallbackToJICA( request, response,
