Java Strikes Again - "Login Error: java.io.IOException: Invalid Http response"

Just a heads up - Java 7 Update 45 has problems and breaks UCSM launching successfully.

You may see one of two errors:

Login Error: java.io.IOException: Invalid Http response

Login Error: java.io.IOException: Server returned HTTP response code: 400 for URL:  http://x.x.x.x:443/nuova

Temporary Workaround: Rollback Java 7 to Update 25 or lower.  A UCSM patch will be released eventually to address this.

Cisco Bug ID: CSCuj84421

Regards,

Robert

Just had this happen in one of our environments, idk if it was a different cause but we got around it by browsing to http:// instead of https:// to get to and launch UCSM.

I got same problem with OSX10.9 Java7u45, and I rollback to Java1.6.0_65, and it still dosnt work.

Any Java7 update 40 or earlier should work. No need to go back to Java6.

I suggest you remove all Java instanses and re-install Java7u40 or less.

Cisco is about time to move away from Java. most of the times there is a java update some cisco application won't work.

is any Cisco developer reading these forums?

Happened to us too, on multiple machines. Rolling back Java did fix it.

Does this imply that a patch for 2.1. is forthcoming?  This is affecting our 2.1(3a) environment as well.

New Member

There will be a fix for 2.1 firmware and 2.2 should be Java 7 Update 45 compatible.

Go to https://tools.cisco.com/bugsearch/bug/CSCuj84421and save the bug to your profile in order to get updates and patch notifications.

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

Has anyone tried "thinapp'ing" the UCS manager + matching Java version? I manage multiple clients with different UCS versions ( 1.4, 2.0 , 2.1)and switching between Java 6 & 7 is a hassle.

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

there appears to be a workarround

enable http and disable https redirection

we found the workarround in this post

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

This workaround is not secure as everything will be sent in clear text.  This will extend threat surface of your UCS environment to anyone or anything on your network.

New Member

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

also there is a ucs update that addresses the issue.

it was just released

if your packet will be sniffed inside your network then you have bigger issues to worry.

till the upgrade, the workarround works fine.

till next java release and here we go again.

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

Hi,

number of my customers reporting same problem, Java 7 update 45 seems to be "unlucky" build. You can solve the problem by uninstalling update 45 and installing java 7 update 25.

Cheers,

Re:Java Strikes Again - "Login Error: java.io.IOException: Inval

Tomek,

UCSM 2.2 was released yesterday and it addresses the issue.

Re: Java Strikes Again - "Login Error: java.io.IOException: Inva

Just started updating from 2.1(3a) to 2.2(1b). Java Update 47 is now supported. But run into big issues after updating the first Fabric Interconnect! created a support case 5 minutes ago.

EDIT: Problem solved (work-around). I know it is off-topic, but worth to share. If you have configure another line-rate setting in your QoS policies you might run into numerous failures when you update you first FI to 2.2(1b). Once I set my the QoS policies settings back to 'line-rate' everthing started working again. This is just a quick reminder for those who want to get rid of the Java incompatibility and start updating.

All,

We are running 2.1.1f in 4 seperate domains, and can successfully log into them with 7 U45, but have noticed that if the http is redirected to https, the login will fail. You can change this under Admin (filter All) communication management > comminication services from witin the GUI, or at the CLI under scope system > scope services disable http-redirect

uninstalling java 1.7 entirely fixed this issue for me, but i agree, Cisco needs to stop using Java for their interfaces. you can get the same level of dynamics in a console that uses no java at all, just look at F5.

So the UCS system I am trying

So the UCS system I am trying to connect to is on 2.1(3a) and I am running Java 8.20 and receive this message:

 

Login Error:

Do you have to reboot UCS to recover?

 

What is the newest Java version that UCSM will work with?

 

.....and please hurry up and get the HTML5 version out!

Pat_devine,

Thnx Kenny.....I went to the

Thnx Kenny.....I went to the 7U25 version mentioned below and was able to access the system.....it is painful to have change versions depending on which Cisco application you are trying to access.....Can't wait for them to get rid of Java for UCSM.

Yes, Robert just mentioned
