First we need to see the UDF logic to suggest you about where you really getting this Null Pointer Exception. When you try to assign or access value from a null object, then you get this exception. You need to check whether you are passing value properly to the UDF input parameters. Also check your coding line by line by debugging. You can use log trace methods to debug the line easily. 

You can add debug statement as below for logging

Example:

container.getTrace().addInfo("your message");

You might also want to check this link for writing log traces using container object in the UDF.

Hi Bhaskara,

Take the source xml from sxmb_moni and put in the test tab on message mapping or/and opertation mapping in order to determine where the error could be. Have you checked that the operation mapping has assigned some kind of mapping?

Hi,

Ur UDF is the culprit so you have to see why it is failing?

Check if u r passing any input to that UDF (copy source payload for which error is coming and then chk the same under mesage mapping) and also what values it expects to behave correctly...so basically a small debugging is required.

Thanks

paste ur UDF code here

You have an error in a UDF. Take a Java environment and debug the program (if you can't find it looking at the code). This is basic knowledge.
