hi sir iam new to web methods,how 2 convert all student names to Upper case?
here
i invoke a service,and declare an array names ,it initializes all de values,but in output array it shows null values,can u help me how it is?

i guess you are using a Java service to do that. regardless; the supported data types can be found at the end of the developer_user_guide.pdf ( in my case its 7.1.1) .
debug the “array” value in the “java” code itself then you can go to pipeline and compare what datatype you defined and compare values ( string list, document list, or object list)

hope this help.

If you are interested you can attend one of the coaching courses provided by us:
Integration Server - flow service, pub sub , webservices , java services

Duration : 1 hr
Delivered one on one via webex live session.

Please email me if you are interested.

Here’s sample code for a Java service that takes a String List named “in”, converts all values to upper case, and outputs the result in another String List named “out”

Good luck,
Percio
