UCF Session Wait Time Out

UCF Session Wait Time Out

Recently I faced this issue. This was the consequence of the some update patches done on the server. As a result the compatibility issues raised between IE and Java versions.

Due to update in patches by Java each time when these update takes place, default settings override the existing settings in IE. As a result the Java get unregistered with the browser, result, Documentum shows message during applet operation - your browser don't support Java, UCF Wait Timeout or just a blank window with no progress bar shown and you are stuck forever.

However, there are few configuration thorugh which you can get rid of this -

1) Ensure you have latest Java version installed on your server and client

2) Ensure you have latest IE browser version installed on your client machine

2) Check your Internet Options for Java Applet

3) Verify that your Java Plugins are enabled properly

4) Check that next generation java plugin is disabled

1. Latest Java Version

Latest Java version will ensure maximum security updates and any new enhancements in java framework. All Java versions have backward compatibility to their previous versions for minimal impact. To Install Latest Java, just go to the java site. You can Google it out on internet. The java site will automatically check for the version of java you have installed on the computer or you can opt for the executable download for the another computer, in case you are not downloading it on your target machine.

2. Latest IE Browser

Browser is your window to the world. Keep your browser updated whenever possible. Most of the companies keep on updating their browser version through security patches, fixes, new functionality. Latest browser version means improved performance, faster response, safety from latest potential threat etc.

3. Enabling Java Applet for your browser

Sometimes having latest version of Java and browser is just not enough. You have to enable certain configurations in order to use them. These can be found in Tools-> Internet Options... ->Security Tab. You can set custom level for each of the internet, local intranet, trusted sites and restricted sites by enabling ActiveX to atleast prompt for your action. Further, set the advanced options in 'Advanced' Tab enable use of JRE under Java(Sun) heading, if it is not there, probably your JRE is ot properly installed.

4. Manage Add ons

Add-on are like extensions or additional features that extend the functionality of your browser. These are DLL files which can be enabled or disabled based on the requirement and frequency of use. Open your browser Add-ons by Clicking on Tools->Manage Add ons...

Verify that the Java related plugins are enabled if not enable them.

5. Disabling Next Gen Option

This is a new option added in JRE 1.6.0_10 onwards. Follow the steps below to disable it -

1. Go to Control Panel->Java

2. Under Advanced tab, disable the next generation java plug-in under Java Plug-In

Clear any cache of browser and delete any temporary files.

Delete this documentum folder mostly found on location: C:\Documents and

Settings\USER_ID\Documentum, or take backup.

Kill java process

Kill javaw process.

Restart browser and login webtop application.

Hopefully, the next time you open your applet window, you won't see the incompatibility issue.
