we are calling a java service and receiving message embeded in response as
“String index out of range: -1”
but the same service when invoked from other servers with same input gives us correct response.
any ideas please

thanks,

One likely possibility is that something is trying to locate a specific character in a string (something other than the input data), and then doing a substring. The find isn’t finding the character and so is returning -1. Then the code isn’t checking that result, and is trying to do a substring of the string. Which fails.

Search for uses of pub.string:indexOf and/or pub.string:substring to help you zero in on the offending code.
