Do I need to un-install old JRE versions prior to the new JRE?
Generally no, but there are instances where issues may arise and you may have to reinstall java. If you find yourself in a situation where you need an older version it is advised you install the older version then the newer version(s). Installing java versions in a non-sequential order will cause you issues.

Administrator Permissions: during installation, a Warning window states "This account does not have sufficient privileges to install Java(TM)..." or "When I try to start a responsibility, nothing happens."
The Windows account does not have Administrator permissions or equivalent. Re-logon to Windows as Administrator or equivalent.

All browser windows close after choosing an Oracle responsibility.
An additional symptom is Java Control Panel (within Windows Control Panel) will not open.

There is a Java conflict with an Add-on. This can be difficult to resolve.
Add-ons can be disabled individually in Internet Options, Programs tab, Manage Add-ons button. On one occasion, all Adobe products had to be Uninstalled to resolve the conflict. Reinstalling current versions restored functionality.

Internet Explorer has encountered a problem and needs to close.
Internet Options, Advanced tab, uncheck 'Enable third-party browser extensions'.

What about "Your current security settings prohibit running ActiveX controls on this page. As a result, the page may not display correctly."?
It is recommended to put the IS site in the Trusted Zone (click for directions).
Otherwise ...

Internet Explorer's ActiveX settings may prevent successful operation. To set this in Internet Explorer, first close all Windows applications. Then click on Tools, Internet Options, Security tab, Internet icon, Custom Level button. Set:

"Download signed ActiveX controls" to Enable or Prompt,

"Download UNsigned ActiveX controls" to Enable or Prompt,

"Run ActiveX controls and plugins" to Enable or Prompt.

Upon completion of the installation of Java, the security level for the Internet zone should be reset to the Default, which is Medium. On Internet Explorer menu bar, click Tools, Internet Options, Security tab, Internet zone (the globe), Default Level button, Apply, OK.

Pop-up Blockers can prevent access:
Some pop-up blockers (like the Google & Yahoo Toolbars) have been known to prevent the Java window from starting, thereby denying access. Additionally, pop-up blockers have prevented users from being able to "View Output" and open certain forms.

Some pop-up blockers may be configurable to avoid this problem. For example, the Goggle toolbar can be configured to allow pop-ups from www.virginia.edu pages, yet continue to block pop-ups from other sites.

(XPSP2) Pop-up blocker and how to configure it for IS compatibility.

How to determine the default version of the JRE on Windows:
To determine the default version of the JRE on a system for Windows: Click "Start", Select "Run", Type "cmd" (starts a command-line). At the prompt, type "java -version" (without quotes). Note: This command only determines the default version. Other versions may also be installed on the system.

Enable Java Console:
Enable the Java Console on your PC through the 'Java Control Panel' by clicking on the 'Java' icon within your desktop clients 'Control Panel'. Select the 'Advanced' Tab and expand the 'Java Console' field. Make sure the 'Show Console' option is selected.

Clear Java Cache:
On occasion, it may be required to flush the Java cache (Temporary Internet Files). In Control Panel, select Java, General tab, Settings button, Delete Files button, OK, OK.

By default, the actual location is C:\Documents and Settings\<YourUserID>\Application Data\Sun\Java\Deployment\cache.

Windows Vista JRE Cache Directory: The JRE cache directory can no longer be changed within the Java Control Panel. The Change button has been disabled under 'Java Control Panel' -> 'General' (tab) -> 'Settings' -> 'Location'.

The default cache is set to a low-integrity directory under the users home, i.e. C:\Users\<username>\AppData\LocalLow\Sun\Java\Deployment\cache.

Users wishing to change the cache location must do so through the deployment.properties file. (At the user level, this is located at C:\Documents and Settings\<username>\Application Data\Sun\Java\Deployment\deployment.properties)

For information on updating the deployment.properties file, please reference the 'Deployment Configuration File and Properties' document on the Sun web site at:

Can't View Output:
Symptom: User clicks View Output button and nothing seems to happen.
This can be caused by browser settings blocking downloads. Adding the IS to the Trusted Zone in Internet Options may be a solution. Please see Trusted Zone below.

(2/18/09) The output may not be visible. In Internet Explorer with tab viewing enabled, View Output opens a new tab to display the data, but its not in the active window. To get the new tab to display in the foreground: Internet Options, Tab section (near bottom) Settings button, Check "Always switch to new tabs when created.", OK, OK. You may have to close and restart all browser windows for the setting to be effective.

Can't Export data?
The export function is usually prevented by restriction of the “Automatic prompting for file downloads” being disabled in Internet Options.

Quick workaround for XP users: To circumvent the block, hold down the Ctrl (control) key during the Export process. Specifically, after the File/ Export, a red progress indicator displays. Depress and hold the Ctrl key until the File Download dialog box is displayed.

Adding the IS to the Trusted Zone in Internet Options may be a better solution. Please see Trusted Zone below.

To enable “Automatic prompting for file downloads” only: Close all browsers. Click Start, Settings, Control Panel, Internet Options, Security tab, Internet, Custom Level, scroll down to Downloads/ Automatic prompting for file downloads, click Enable, OK, Yes to changes, Apply, OK.

Automatically Export to Excel?
The Export downloads the file fnd_gfm.tsv. The File Download prompt has Save/ Cancel buttons only if the TSV file is not associated.

If that file type (TSV) is associated with Excel, the File Download dialog box prompts the user to Open/ Save/ Cancel. On that File Download dialog box, there's a check box for "Always ask ..." If that box is UNchecked and you click Save, the subsequent exports will simply open in Excel automatically.
To un-do this and regain the Open/ Save/ Cancel box: start Windows Explorer, Tools, Folder Options, File Types tab, scroll down the Registered File Types list, click to highlight the TSV file type, Advanced button, uncheck and then check the "Confirm Open After Download" box, OK, Close.

If TSV was associated with another program, such as notepad, the association can be changed as follows. In Windows Explorer, navigate to a saved copy of fnd_gfm.tsv, right click, Open with, Choose From a List, choose Microsoft Excel, CHECK the "Always use box", OK.

Can't open attached files.
File Download needs to be enabled. In Internet Explorer, go to Tools, Internet Options, Security tab, click Internet zone, Custom Level button, set Automatic Prompting for File Downloads to Enabled.

Adding the IS to the Trusted Zone in Internet Options has proven to be a solution. See Trusted Zone below.

Adding IS to the Trusted sites?
It is suggested that the Integrated System server be added to the Trusted Zone in Internet Options. This allows for fewer restrictions on the IS site while retaining more restrictions for public Internet traffic. This helps resolve issues with Export failure and file attachment failure.

Add to Trusted Zone: You may need Administrator privileges on the PC to set Internet Options.
Close all browsers. Click Start, Control Panel, Internet Options, Security tab, Trusted sites, Sites button, enter
https://e1prdw2.admin.virginia.edu
in the "Add this Web site" box, Add button. One should also check the "Require server verification (https:) for all sites in this zone" box. OK, Apply.

After adding IS to the Trusted Zone, modify the Trusted Zone security level to Medium-low.
Then click Apply, OK.
