Re: Problem for access webtools from internet explorer or firefox with JRE 1.7!

Open the java.security file which is located in your client machine's Java/JRE installed directory (jre/lib/security/java.security).

Look for this line:

jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024

Change 1024 to 256 and save.

 

That worked for me.

Put the following, instead of what you have,  in the java.security file:

 

jdk.certpath.disabledAlgorithms=MD2

Re: Problem for access webtools from internet explorer or firefox with JRE 1.7!

I tried all of the above and none worked but his did from this blog http://www.richardnichols.net/2012/08/arrrggh-java-security-cert-certificateexception-certificates-does-not-conform-to-algorithm-constraints/

 

JDK7 changed the default Java security settings to disable MD2 algorithm to sign SSL certificates.
BUT this can be re-enabled by editing JDK_HOME/jre7/lib/security/java.security and commenting out the following line:

jdk.certpath.disabledAlgorithms=MD2

... becomes ...

#jdk.certpath.disabledAlgorithms=MD2

Re: Problem for access webtools from internet explorer or firefox with JRE 1.7!

Thanks all for the detail on security that was already a first step to resolving my issues.

But now that I can access it it take about 3 to 7 minutes to open a webtool with JRE1.7 when it take about 30sec in JRE 1.6

My switch are still running 6.4.3d but got same behavior to 7.1.1 and running BNA 12.0.3

 

Anyone did get same issue ?

Or did you found a way to force BNA to use the older version of JRE and not its own 1.7 version ?
