If you attempt to generate the sample JSP™ test client using the Web Services Wizard in Rational® Application Developer (RAD) with an array class defined in the input, the array is not understood as an input.
The sample JSP client generated by the RAD Web Services Wizard cannot handle flexible types such as arrays as operation inputs, but it can handle arrays as operation outputs.
Resolving The Problem
To work around this issue, you can edit the generated sample JSP test client and write code to render forms that better handle your particular use of array inputs and outputs.
