NullPointerException: while trying to invoke the method in java mapping sap pi

[Former Member]

Hi Experts,

I created Java mapping to convert XML to Excel but while executing in SAP PI 7.4 I am getting errors. my PI version is 1.6_45, I compiled class and created jar file in java 1.5version. while testing  in operation mapping and end to end testing we are getting errors. Below I provided error information and attached source data and java code .

please provide your valuable inputs to resolve this error.

Runtime error:

Transform: failed to execute the transformation:

Hi Seshagiri,

From the exception trace it looks like this line is where the error is getting triggered in your mapping:

if(nodeValue != null && nodeValue.equals("<EOF>"))

The part that doesn't make sense here is if this code matches your deployed mapping then a NullPointerException should never occur because the if statement will short circuit when nodeValue == null.  I'd double check the deployed code to make sure that the check on the null condition exists in your mapping.

Regards,

Hi All,

   we fixed the null pointer exception using some code changes now mapping working fine. We generated another code using sax parser that's also working fine. End to end testing also its working fine.

  thanks all for your inputs.

Thanks,

Seshagiri.

Try to change UTF-8 to ISO-8859-1 and repeat the test. I guess that in your xml there are non UTF-8 characters.

Use for instance <?xml version='1.0' encoding='ISO-8859-1'?> instead of <?xml version='1.0' encoding='UTF-8'?>

Hi Seshagiri,

I have checked your mapping code and there is nothing wrong in it. You are getting null pointer exception because of fields missing in last record in input xml payload. Try to remove marked incomplete record and test it again.

[Former Member]

Hi All,

thanks for your inputs we resolved this mapping runtime error now we are able to create excel file but file contains some junk value along with data. please suggest solution.

[Former Member]

Hi Seshagiri,

When I test this as standalone java program with Main() method I am getting proper excel sheet without any junk values.find below screenshot

[Former Member]

Could be related to Excel version?

[Former Member]

Hi Seshagiri,

If you want, u can add below marked code in your java mapping. This allows you to update the number of fields present in the incoming xml payload into the Excel.

[Former Member]

Hi Rao,

standalone its working fine.its resolved actually when file placed in target directory by default file opening with notepad that's why we got junk values.

Thanks,

Seshagiri.

It is afterall java compiler error.

Google it more, you will get many hits.

I feel it is encoding issue.

Hi mate,

    Maybe you can try a soft workaround using PI.

Good luck, I can't help more i guess
