Java 8 and Nolij Web

Java 7 is the only version certified by the vendor to work with Nolij Web.  Nolij Web 6.7 has not been certified to run with Java 8. Java in the browser provides the scanning and file-explorer (ability to drag files from the desktop into Nolij) features.  If you are not scanning or importing files into a student record from your machine, you can safely ignore the nagging Java alert.

Most browsers have disabled the NPAPI plug-in (technology required for Java applets).   This leaves us with Internet Explorer.

If you have accidentally updated and need to scan or upload files from your machine, please open a service desk request to be back leveled. For other issues please see either the Frequently Asked Questions or the common problems page  

Reporting Issues to the Vendor

We can enter questions/issues/enhancement requests.   All our current issues are listed under 'Cases'.

 Multi-page TIFFs incorrectly created when scanning in color
When scanning a color document using CaptureNow Adrenaline, multi-page TIFFs are created instead of single-page TIFFs as expected. As a result, the image file can exceed several megabytes in size.

The following workarounds are available:

  • Scan in black and white.

  • Request a TWAIN or a ISIS license from a CSA to replace the CaptureNow - Adrenaline license.

  • Scan outside of Perceptive Content, and then import the file.

 Batch folder appearing in mailboxes of other workflow

Open Case ID: 01280148

Nolij Web: Batch folder appears duplicated in a non-batch workflow

The bad news:   Neither the PSI support engineer nor his manager could duplicate the issue.  We’ve agreed to close the ticket with a known issue number (bug ID)  logged for the case.   The display of the batch folder in the Student Workflow is clearly just a pointer.   Deleting the folder and documents is definitely not an option.  We do not know how to prevent this from happening again because we do not know how it was done in the first place.  It is not something one of our folks would do intentionally.  This behavior is  "by design" not supposed to be possible.

Mildly good news:  This is being tracked by PSI and we are asked to alert them as soon as we see this behavior again.   Our first response is to pull log files and run queries on the various Nolij Web tables to track the workflow history on any documents/folders “moved” from one workflow into another.

The other good news is that we have a relatively simple means to suppressing the erroneous folder(s) from being seen in the wrong workflow: we need only delete one of the associated entries from the kw_wfhistory table. 

 Nolij Web 6.7 cannot run with current version of Java 8.
Nolij Web 6.7 has not been certified to run with Java 8. If you have accidentally updated, please open a service desk request to be back leveled to 32-bit Java 7. For other Java related issues please see the common problems page. 
 Problem viewing certain document types within the Nolij Document Viewer
If you see a pop-up saying "Document Viewer Unable to Load the Document"  please double-click the document (it might take more than once) to "app activate" and bring the document up outside of Nolij in another tab of your browser or other associated application which you have set as your desktop default for that file type. 

There is a known problem with trying to view a few document types within the Nolij Document Viewer panel, particularly .mht file types and some PDF file types.  The document types that most often have a .mht filename extension are DARS related,  and the PDFs most frequently causing grief are transcripts.   We have an open issue with the vendor -- PSI Case Number: 00940961,  as well as Incident 152290 in our own ITS Service Desk.
 Minimize the Workflow/View area, but the change does not stay in place.

This is an open defect in Nolij Web up through 6.8.  User minimizes the Workflow/View area and File Explorer pane in order to expand the Form pane, but the change does not stay in place.


– PSI Case Number: 00954496 and Incident 1450 in ITS UAD Issue and SR Tracker
 NolijWeb does not load after updating Java to 1.7.0.51.

Java 1.7.0.51 and greater can be used if the slider in the Java Security panel is turned down to medium. 

As a workaround, follow these steps.

  1. Close all internet browsers.
     
  2. Uninstall all versions of Java.
     
  3. Install the Java build of 1.7.0.45 from Oracle's site.

The following may also need to be done to delete the old Java files and to change the security after the re-installation.

  1. After the installation has been completed, open the Java console by going to Start, expand All Programs, click Java, and then click Configure Java.
     
  2. On the General tab, click Settings, and then click Delete Files.
     
  3. Check all three boxes, and then click OK to delete the old files associated with Java.
     
  4. On the Security tab, change the security level to Medium, and then click OK.
     
  5. Restart the affected machine.
 Java error when logging in to Nolij Web, "(TypeError) $doc.getElementByld..."

When a user attempts to log in to Nolij Web, the following errors occur:

"Nolij Web cannot communicate with a Java applet. Java applets and the features associated with them have been disabled. getChildrenFromApplet failed"

"(TypeError): $doc.getElementById(...).getChildrenFromAppletAsString is not a function..."


Resolution

These errors occur when the internet browser's Java plugin is disabled. Mozilla Firefox blocks some plugins due to security vulnerabilities, which includes many instances of the Java plugin. A list of blocked plugins and their reasons can be found on the Mozilla Blocklist.

To resolve the issue, either manually enable the plugin or install a version of the Java plugin that is not affected by a security vulnerability.

To manually enable the Java plugin, follow these steps for Firefox or Internet Explorer:

For Mozilla Firefox:

  1. In Firefox, press Ctrl+Shift+A to bring up the Add-ons Manager.
     
  2. On the left panel, click Plugins.
     
  3. Find the Java(TM) Platform plugin and click the Enable button. You may need to restart the browser for the changes to take effect.
For Microsoft Internet Explorer:
  1. Click the Tools menu.
     
  2. Click Manage Add-ons.
     
  3. On the left panel, click the drop-down arrow and select All Add-ons.
     
  4. Find the Java Plug-in and click on it to show the details in the bottom panel.
     
  5. On the bottom panel, click the Enable button.
For Google Chrome:
  1. Enter about:plugins in the URL bar.
     
  2. Scroll to the Java section and verify if Java is enabled (if the Disabled link appears, then it is Enabled).
     
  3. Click on the Enable link (if available).
     
  4. (Optional) Select the Always allowed option to stop additional Chrome warnings when running Java content.

 Error message "Java has discovered application components that could indicate a security concern"
When a user logs in to Nolij Web, the following message occurs.

"Java has discovered application components that could indicate a security concern. Contact the application vendor to ensure that it has not been tampered with."

Resolution

This issue has been resolved in Nolij Web Version 6.7.9 and above. The message that appears is due to an increased Java security setting. To increase protection from security threats, Oracle has raised the default security level of Java to High in the latest versions of Java 7 (update 11 and higher).
 Java security warnings for Nolij Web after upgrading Java to 1.7.0.45

After upgrading Java to 1.7.0.45, a security warning appears when launching Nolij Web.

Selecting Do Not Allow prevents the Nolij Web scanning and file-browsing applets from working, where selecting Allow lets Nolij Web run without issue.

 Java Applet Errors -- Info on the pop-up

Information on the Popup message to  " Block Potentially Unsafe Components From Being Run "

This behavior is due to an increased Java security setting. To increase protection from security threats, Oracle has raised the default security level of Java to High in the latest versions of Java 7 (update 11 and higher).

The workaround is to click Don't Block every time the message appears. The message cannot be avoided without turning off Java security, thereby opening up the system to security threats.

How to turn off message (may have to do the 2nd part for pop-up to not appear):

Java Applet Errors

When Nolij Web loads, it requests the browser to load an applet. The browser should either start Java Runtime Engine (JRE), if it is installed on the computer, or prompt you to download JRE.

However, you may receive messages in Nolij Web or from your browser about Java errors, such as problems communicating with Java Applets or RuntimeException errors. This would be because: 

• You may have permanently rejected the prompt to download and install the appropriate version of JRE.

• The browser is configured to reject applets.

• An older version of JRE, incompatible with Nolij Web,  is installed on your computer.  Please contact your Technology Coordinator https://wiki.albany.edu/display/askit/Technology+Coordinators for help installing Java 7
