How to trace java.lang.NullPointerException error.

Can someone please tell me how to debug java.lang.NullPointerException errors? I have an automated solution written in groovy and every so often in the error log I get the line: ERROR:java.lang.NullP...

If you run one more time, it may show up as Script3 and so on.

Hi thanks for the replies.

 

I have *never* received an error message like yours where it clearly shows the line number responsible for the error. I've been using SoapUI Pro since around September 2014.

 

I run my tests via a Groovy script. The main script runs on a loop that is on a timer of one hour. Each time that script executes it calls a driver script that runs all the test steps in turn for each test case. It is automated. Even running the scripts manually I never get a line number for the errors and never have done. It's really frustrating.

 

Regards

    Hmm. May you want to try the same example that was shown in the screen shot to see atleast that shows same error as above?

    Hi Rao,

     

    Thank you for your continued interest in helping me and your assistance.

     

    I was able to reproduce the example you showed easily:

     

    err_001.png

     

    By looking at your earlier post I was also able to determine that the error I receive earlier is indicating line 11 of the script is responsible (thank you for helping me find this). However, looking at line 11 in *all* scripts does not reveal a use of the variable mentioned. It only mentions 'Script 1' as the cause and line 11 of this script. Since I have no idea what Script 1 refers to I had to check all my scripts. As I said previously I have done a Find to see where the variable is being used but it is not found in any script I am using. I am totally puzzled. If a variable is not longer in use (as it cannot be found by a Find & Replace) then why does SoapUI keep complaining about it. It doesn't even appear to cause any problems but it is exceptionally irritating to see this in the error log all the time.

     

    Regards

    That's fine.
    Just to confirm that you were able to proceed, right?

    Hi,

     

    Yes I can proceed as it doesn't seem to cause any visible problems and I get the correct results. My issue is why the error log is reporting an error with a variable I no longer use. It isn't found in *any* script I have. It undermines my confidence in the product when it reports false problems.

     

    I have discussed this and various other issues with my line manager and we have decided to switch to using JMeter instead so we are no longer going to be using SoapUI Pro and therefore this will cease to be a problem.

     

    Thank you so much for the time you have spared me on this issue, it was really appreciated.

     

    Regards

     

    Gary.
