TechTips - NETAPP SAN JAVA Error - There was an Error While Executing the Application in Java

This is a very common Java error when you are working within the controllers of a NETAPP san via the web browser interface. It's not uncommon and it's easier to fix than you might think. I am not sure why the error occurs but a simple change to Java will fix it 90% of the time and if that doesn't work then we will just uninstall and reinstall Java and this fixes the problem 9% of the time. If neither works then you are the 1% which I have never seen and hope I never have to.

So first let's try the most common fix to the problem, we will want to modify the security settings of Java. To do this follow these steps:

1. Click Start

2. Click Settings

3. Click Control Panel

4. Double Click the Java icon

5. Click the advanced tab

6. Expand the security option by using the plus sign

7. Find Use TLS 1.0 and uncheck the box

8. Click Apply

9. Click OK

10. Close your web browser window and reopen it go to the page that gave you the error and try it again

11. It should work

Now if for some reason the above options didn't fix your problem you might have a corrupt install of Java or it might be an extremely old version. So we are going to uninstall Java and then reinstall it. So first get the most recent version of Java here. Get the latest version, just download it don't install it just yet. Next we will uninstall the old version of Java to do this follow these steps:

1. Click Start

2. Click Settings

3. Click Control Panel

4. Double Click Programs and Features

5. Find Java™ # update #, highlight it and choose uninstall

6. Let the uninstaller do its job, once finished close all windows

7. Double click the java installer where ever you saved it

Let the Java installer go through its process of installation. Once it's done go back and try your application, it should work. If it doesn't work still then I really have no idea what is going on with your application and you will probably want to consult Google or another resource on the internet. Hope this guide help s to get you going again.

This isn't necessarily just a Netapp SAN Java error, I am sure this error occurs in other applications but I found it is most commonly associated with the Netapp SAN user interface. So if you are getting this error elsewhere you can still try this fix to see if it helps.
