A problem with prototypes for Java wrapper

I have a java program that I'd like to wrap with RPG. This is the first attempt I have made at something like this (including placing prototypes in a separate member and /copying them in). So there may because something obvious here that my ignorance is covering. When I compile the module, I get the following (V5R3M0):

A d d i t i o n a l D i a g n o s t i c M e s s a g e s Msg id Sv Statement Message text *RNF7535 30 000181 The type and attributes of parameter 9 do not match those
of the prototype. *RNF5406 30 000178 The call passed fewer parameters than the prototype
indicates are required.
I know what it is saying but looking at my code and the /copy member I don't see the mismatch.

Here is the relevant /copy:

*--------------------------------------------------------

* RPG Wrapper for RRGenerator_iPrintReport

D rrg_iPrintReport...

D prHost like(jString)
D prLibList like(jString)
D prUserID like(jString)
D prPassword like(jString)
D prReportName like(jString)
D prReportOut like(jString)
D prRepParam like(jString)
D prOutFormat like(jString)
D prCompile 1N value

*+++++++++++++++++++++++++++++++++++
D RRGenerator_iPrintReport...

D .Generator'
D :'iPrintReport')
D host like(jString)
D libraryList like(jString)
D userID like(jString)
D password like(jString)
D reportName like(jString)
D reportOutput like(jString)
D reportParam like(jString)
D outputFormat like(jString)
D compileFirst 1N value
The call is here:

P rrg_iPrintReport...
P B EXPORT
D rrg_iPrintReport...
D PI 1N
D peHost like(jString)
D peLibList like(jString)
D peUserID like(jString)
D pePassword like(jString)
D peReportName like(jString)
D peReportOut like(jString)
D peRepParam like(jString)
D peOutFormat like(jString)
D peCompile 1N value
D success s 1N
D

/free

success = RRGenerator_iPrintReport(peHost: peLibList: peUserID: <-- Line 178
pePassword: peReportName:
peReportOut: peRepParam:
peOutFormat: peCompile); <---Line 181

return success;
/end-free

As I count/compare parameters and types it looks good to me. What I am I missing?

Thanks,
