Java error : Unable to launch the application when trying to open up DELL iDRAC console !

I updated java on my machine today since one of the web application demanded the update. Post java update, the web application started working (sigh). I was happy that, I don’t have to deal with java again.

After a while, for some maintenance activity, I connected DELL iDRAC ( Integrated Dell Remote Access Controller ) through web browser and wanted to access remote console.

Viola ! an error popped up saying ” Unable to launch the application.” Wow, Another java problem ! Java at its best ! ;-)

java error


I tried to delete java ‘trace and log files’ and ‘Cached Applications and Applets’ from java control panel but in vain.

I even removed and re-installed java but in vain.

What finally saved my day was, changing ‘Network Settings’ in java control panel.

Instead of ‘Use browser settings’, I selected ‘Direct Connection’. Bingo ! when I reinitiated remote console access, it worked like a charm :-)

java error 3  java error 4

By the way, Java Control Panel can be accessed through

Start / Control Panel / Java

java error 5

Hope this info will help someone.

    I had also to change the security level for medium. Tks

  4. Excellent post! It’s been a while since I’ve been on my remote system through my DRAC. Thank you!

    Like Eduardo, I had to set my security settings to medium… The high setting still suppressed the window. Thank you Eduardo!

    First off, thanks to Santosh for this post. I had the same problem and this post resolved it for me. Similar to Eduardo and Darin, switching the network setting to a direct connection wasn’t enough as the security level was an issue.

    I didn’t want to switch the security setting down to medium though. What I did instead was add an exception to the exception site list for the iDRAC card’s site/IP address. I have my Java client security level set to Very High and with the exception set on the list, it works just fine. Might be a better choice than to lower your Java client’s security level to medium?

    Thanks again for everyone’s input on this post!

    Thanks, Eduardo, for your post. That made the difference in my case too. Hope we all remember to reset it to high once we’re done …

    I have the same problem -> Solution: Go to control panel -> Java -> Security tab -> Edit site list -> add url from application error form (the extention is .jar) -> Ok
