required arguments in Flex 1.5 - kills webservice

I am running Flex1.5 with Tomcat 5.0. I dropped the samples.war file in webapps
and everything worked great.

I am planning to use on example, the NamedWebServiceDemo, with mods as my
first application. I simply recompiled the EmployeeManager.java file in
{tomcat}\webapps\samples\WEB-INF\classes\samples\explorer in preparation for
actually changing it a bit. NOW the application fails with the message:

Required parameter 'in0' not found in input argument.

I did find one reference to this error
(http://www.macromedia.com/support/do...migration.html)

message stating that 1.5 enforces arguments. I did not change arguments for
anything and this should still work. I decompiled the included class file and
it is, except for variable names, identical to the file EmployeeManager.java
file that I have.

I am stuck! I do not see how to get around this behavior.
