WebNow/eForms - Java Error: Missing required Permissions manifest attribute in main JAR

posted Jan 15, 2014, 1:02 PM by John Brown   [ updated Aug 25, 2014, 7:31 AM ]

Note: Patches applied to WebNow and eForms on 8/23/14 have corrected this issue. Users should no longer be getting the Security Exception related to the Permissions Manifest Attribute. It is no longer necessary to follow the steps below to add sites to the Java security exceptions list.

Issue: Java 7 Release 51 has introduced additional security settings that block applications without an up to date "Permissions manifest attribute." The version of WebNow currently maintained by the University of Maine System does not have this attribute set. Due to this, any user with Java 7 Release 51 or later installed will be unable to access WebNow, receiving an error message referring to the "Permissions manifest attribute," as seen below. This issue also impacts any ImageNow eForms that are in use.

WebNow Error



Resolution: As a workaround, it is possible to add the WebNow URL to a list of sites with exceptions. This will tell Java that WebNow is a safe application to load. Below is the process to do this.

NOTE: If you do not see the same security options in the Java Control Panel as appear below, you may need to still update your version of Java to Release 51. This can be done through www.java.com. 
  1. Navigate to the Java Control Panel and open it
    • Windows/Mac - Open your system control panel or System Preferences and choose Java
    • Linux - Run the jcontrol command
  2. Click the Security tab:


  3. Click on Edit Site List
  4. Click on Add
  5. Enter the WebNow URL - http://webnow.unet.maine.edu:8080/webnow/ - into the Location field, as shown below:


  6. Click Add and then enter the MaineStreet WebNow URL - http://webnow.its.maine.edu:8080/webnow/ - into the Location field, just as in the previous step


  7. Click Add and then enter the ImageNow eForms URL - http://imagenow.unet.maine.edu:8080 - into the Lcoation field, just a in steps 5 and 6


  8. Click OK, and the following prompt will appear. Click Continue on that prompt.


  9. Back on the Security tab, the Exception Site List section should like like it does in the image below. If it does, click OK and relaunch WebNow. Otherwise, repeat the above steps to get the WebNow URL added to the Exception Site List.


ImageNow 6.7 - Unable to access a document in workflow in a Working state

posted Aug 15, 2013, 1:22 PM by John Brown

In the 6.7 version of ImageNow, connections to ImageNow are tracked by sessions, and not user ID. As explained in an upgrade status update this means that users can be logged into the system from two separate workstations with the same user ID. However, this does cause a new issue - if you are accidentally logged out or disconnected from the ImageNow client while working on a document in workflow, your open document will be stuck with a status of working and may not be accessible to you. Here are the key points regarding this change:
  • Users with a queue lead or manager level access to the queue with the affected document can right-click on the document and select Workflow > Mark Item as Idle. Unfortunately, this ability will only work in regular queues, not in super-queues (those queues with an additional queue name starting with SQ in parentheses).
  • Documents in this state will automatically get their status reset to Idle after a timeout period - this is currently set to 1 hour
  • If neither of the above are options and a document needs to be accessed immediately, UMS ITS application support staff can reset the document's status for you. Please contact us at insupport@maine.edu.

ImageNow 6.7 - Unable to Create File Error or Program Freezes when Logging In

posted Aug 5, 2013, 9:11 AM by John Brown   [ updated Aug 5, 2013, 9:12 AM ]

Problem:
When launching ImageNow 6.7 for the first time, you may experience one of the following issues:
  • The program appears to freeze after putting in your user ID and password and trying to sign in
  • The program generates the following error message when trying to log in:

Cause:
In both cases, the issue appears to be caused by administrator privileges on the computer. This only occurs with Windows Vista, 7, or 8. Windows XP appears to be unaffected.

Resolution:
  • Right-click on the ImageNow desktop icon and left-click on Run as Administrator
  • Log into the client as you normally would
  • Log out and close the client
  • Open the program as you normally would, without clicking on Run as Administrator and log in again
The first step of running as administrator should only need to be run the first time you launch the program after the upgrade installation. The ImageNow client is attempting to create a file it needs to run, but due to security limitation it is unable to do so. Once the file is created, the program will run as it normally should.

ImageNow 6.7 - Toolbar Warning

posted Aug 1, 2013, 8:18 AM by John Brown

Changes to the toolbar settings between versions may cause customized toolbars to reset. The first time a document is viewed after upgrading the ImageNow desktop client to version 6.7, the following message may appear:


If you do see this message, just click on Yes and proceed as normal. If a customized toolbar was used before, it may need to be reconfigured.

WebNow/eForms Certificate Expiration Error

posted May 31, 2013, 11:56 AM by John Brown   [ updated Aug 9, 2013, 8:31 AM ]

NOTE - This issue is now fixed with the upgrade of ImageNow to the 6.7 version.

The trusted site certificate for WebNow and eForms will expire on 6/14/2013. Starting on 6/15/2013, users will receive a certificate warning when accessing WebNow or a form created through eForms.

Important information on this message:
  • The WebNow and forms sites are still safe, and will not compromise the security of your computer if accessed
  • Clicking Run will launch the WebNow site or form as normal
  • Clicking Cancel will stop the site from launching
  • The warning will display, regardless of browser
  • The warning will show regardless of how WebNow is accessed - via the direct address, or through a link in MaineStreet
  • Clicking on the "Always trust content from this publisher" option will prevent the warning from displaying on future visits to the WebNow site or form (see image below)
    • On Macs running OS X, the option is labeled as "Do not show this again for apps from the publisher and locations above"
    • To remove the permissions given for trusting content from a publisher, follow the directions found here
  • The certificate will be updated with the upgrade of ImageNow/WebNow to version 6.7 this summer

WebNow and Java 7

posted May 17, 2013, 11:56 AM by John Brown   [ updated Aug 9, 2013, 8:32 AM ]

NOTE - This issue is now fixed with the upgrade of ImageNow to the 6.7 version.

Over the past few months we have seen a noticeable increase in issues with WebNow, primarily with printing. These issues have been due, in large part, to the installation of Java 7 on the affected workstations. Currently, WebNow does not fully support Java 7. Unfortunately, Oracle is pushing out updates to move users from Java 6 to Java 7, which is leading users to automatically update their system to the newer version. Oracle officially ended support for Java 6 in February of this year. It is our understanding that Perceptive Software, the vendor for ImageNow/WebNow, will be providing an update to WebNow soon that will support Java 7. 

In the interim, we are advising WebNow users, especially those who need to print from WebNow, to not upgrade to Java 7. If you find that this has already happened and you are running into issues with pages printing blank, etc., you will need to uninstall Java 7 and re-install Java 6. This should be something that your local IT support can help you with if you are not comfortable doing this yourself. Note that this issue is only with WebNow and that users of the ImageNow client should be unaffected by the Java update.

I have included a couple of links below which should help with this process. The first is to a tool that will let you check which version of Java is installed on your computer - 6 or 7. The second is a direct link to download Java 6 if you need to re-install it. Please let us know if you have any questions or concerns.
