Instructions for Cognos ReportNet Windows
Back up your environment.

Change directory to the install directory for Cognos ReportNet. (eg. cd c:\Program Files\crn\).

Under the CRN_ROOT directory change directory to the bin\jre\1.3.1\lib\ext.

Within the ext directory, verify if the file jce1_2_1.jar exists.

If it exists, it must be removed from the ext directory (note that renaming will not be sufficient, copying the file to another directory is acceptable) and replaced with jce1_2_2.jar.

Update the JCE by downloading the compressed file and copy all four of the uncompressed files to the <ReportNet_Home>\ bin\jre\1.3.1\lib\ext directory.

for metrics designer look in the \pd1\bin\jre\1.3.1\lib\ext directory.

restart your application(s) and everything works as normal

Not sure what this post is saying. Did you have a problem with your CRN environment and this was the fix? Does this problem happen to many people based on the date you give?

More info please.

In response to your questions, Yes and Yes.

Trying to load ReportNet's web page when you experience this problem results in a

HTTP Status 500 - The server encountered an internal error () that prevented it from fulfilling this request

error page being displayed and it gives you a whole heap of errors about classes not being found.

This could potentially affect anyone's ReportNet environment - its a problem with an expiry of the java JCE certificate shipped with ReportNet.

JCE uses a signed jar verification routine to vet any cryptographic providers. The JCE version 1.2.1 does not allow legitimate providers to load after July 27, 2005. JCE version 1.2.2 addresses this

Sorry Dave,

here is some more info from the cognos site:

Expiry of JCE Certificate May Cause Run-time Failure
in Cognos ReportNet and Cognos Metrics Designer
Advisory Reference: ADVCRN04_0405
Updated: July 15, 2005

Impact: Possible fatal run-time error in Cognos ReportNet and Cognos Metrics Designer



Product(s) Affected
Cognos ReportNet 1.02
Cognos ReportNet 1.1
Cognos ReportNet 1.1 MR1
Cognos ReportNet 1.1 MR2
Cognos Metrics Designer 2.2
Cognos Metrics Designer 2.2 MR1
Cognos Metrics Designer 2.2 MR2
Description
Cognos ReportNet
Existing Cognos ReportNet product for Windows shipped version 1.3.1 of Sun’s Java Runtime Environment (JRE). In addition, Cognos ReportNet for Windows shipped version 1.2.1 of Sun’s Java Cryptographic Provider (JCE 1.2.1). For Cognos ReportNet UNIX, JCE 1.2.1 was provided with instructions to copy to the customer installed JRE, but it was not installed during the Cognos ReportNet installation process.

JCE uses a signed jar verification routine to vet any cryptographic providers. The JCE version 1.2.1 does not allow legitimate providers to load after July 27, 2005. JCE version 1.2.2 addresses this.

Additional information on this issue



To avoid this issue, JCE 1.2.2 must be installed in any JRE 1.3.1 environment. To determine if you are affected by this issue, you must determine if you are using JCE 1.2.1 in JRE 1.3.1 and if so, replace JCE 1.2.1 with JCE 1.2.2. Verify all machines, including Cognos Framework Manager installations.

Cognos ReportNet version 1.1 has fixed this issue in Hot Site kits 1.1.414.36 and above.



Cognos Metrics Designer
Cognos Metrics Designer may also encounter this issue if using ReportNet packages as sources for Cognos Metrics Manager. To determine if you are affected by this issue, you must determine if you are using JCE 1.2.1 in JRE 1.3.1 and if so, replace JCE 1.2.1 with JCE 1.2.2.

Cognos Metrics Designer version 2.2 Windows has fixed this issue in 2.2.100.10.



Suggested Action(s)
To minimize the potential of a fatal run-time error in Cognos ReportNet or Cognos Metrics Designer, we strongly recommend that you determine if your Cognos ReportNet or Cognos Metrics Designer installation relies on JCE version 1.2.1 and if so, download and install the updates for the product applicable to you. Cognos will not be liable for any loss or damages arising from the failure to implement these recommended directions.



Instructions to Determine if JCE 1.2.1 is Installed in Your JRE Environment
To determine if you have JCE 1.2.1 installed in your JRE environment do the following:


Instructions for Cognos ReportNet Windows
Back up your environment.

Change directory to the install directory for Cognos ReportNet. (eg. cd c:\Program Files\crn\).

Under the CRN_ROOT directory change directory to the bin\jre\1.3.1\lib\ext.

Within the ext directory, verify if the file jce1_2_1.jar exists.

If it exists, it must be removed from the ext directory (note that renaming will not be sufficient, copying the file to another directory is acceptable) and replaced with jce1_2_2.jar.

Update the JCE by downloading the compressed file from the link below and copy all four of the uncompressed files to the <ReportNet_Home>\ bin\jre\1.3.1\lib\ext directory.
Instructions for Cognos Metrics Designer Windows
Back up your environment.

Change directory to the install directory for Cognos Metrics Designer.

(eg. cd c:\Program Files\pd1\).

Under the install directory change directory to the bin\jre\1.3.1\lib\ext.

Within the ext directory, verify if the file jce1_2_1.jar exists.

If it exists, it must be removed from the ext directory (note that renaming will not be sufficient, copying the file to another directory is acceptable) and replaced with jce1_2_2.jar.

Update the JCE by downloading the compressed file from the link below and copy all four of the uncompressed files to the Pd1\ bin\jre\1.3.1\lib\ext directory.
Instructions for Cognos ReportNet Unix
Back up your environment.

Determine the JRE used by Cognos ReportNet.

This may be pointed to by the JAVA_HOME environment variable.

Determine the version of this JRE.

If it is version 1.4 and above your installation is not affected by this problem. If you are running version 1.3.1 then proceed to step 4.

Change directory to JAVA_HOME/lib/ext.

Within the ext directory, verify if the file jce1_2_1.jar exists.

If it exists, it must be removed from the ext directory (note that renaming will not be sufficient, copying the file to another directory is acceptable) and replaced with jce1_2_2.jar.
Instructions for Cognos Metrics Designer Unix
Back up your environment.

Determine the JRE used by Cognos Metrics Designer.

This may be pointed to by the JAVA_HOME environment variable.

Determine the version of this JRE.

If it is version 1.4 and above your installation is not affected by this problem.

If you are running version 1.3.1 then proceed to step 4.

Change directory to JAVA_HOME/lib/ext.

Within the ext directory, verify if the file jce1_2_1.jar exists.

If it exists, it must be removed from the ext directory (note that renaming will not be sufficient, copying the file to another directory is acceptable) and replaced with jce1_2_2.jar.
Update the JCE by downloading the compressed file from the link below and copy all four of the uncompressed files to the JAVA_HOME/lib/ext directory.

Alternatively, download the following program to the Cognos ReportNet or Cognos Metrics Designer bin directory and run it. It will display the version of JCE used. This program will identify the JCE version even if the file name has been changed in the ext directory. Note that version 1.2 will be displayed if JCE version 1.2.1 is installed.



JCE Version Display Program
UNIX | Windows



If you have JCE 1.2.1 installed in your JRE environment, you must download and install version 1.2.2. Download the compressed file from the link below and copy all four of the uncompressed files to the appropriate directory.



For Windows platforms, copy the files to the <Cognos_product_Home>\ bin\jre\1.3.1\lib\ext directory. For UNIX platforms, copy the files to the JAVA_HOME/lib/ext directory.
