Question on IBM's WSDL2RPG tool -- Problem with wsdl2ws.sh and GetQuote sample

(also posted same issue to IBM developerworks RPG forum)

I'm trying to get familiar with consuming webservices using IBM's WSDL2RPG tooling. Tried following the instructions in "Web Services Client for ILE Programming Guide" - Chapter 21, to generate the RPG stub code for the sample GetQuotes operation. When I try the wsdl2ws.sh command in qshell, I get rejected with:

"java.io.FileNotFoundException: /home/MKOESTER/QIBM/ProdData/OS/WebServices/V1/client/samples/getQuote/GetQuote.wsdl (a file or directory in the path name does not exist.)"

Okay, I deviated from the instructions where it said to create a library "MYGETQUOTE". The SysAdmin doesn't go for anyone creating libraries here, so I figured I could use my assigned development library, "MKOESTER" and substitute that into the command for the two occurrences of MYGETQUOTE.

I'll also confess to there being a folder named MKOESTER in the home directory on our IFS, but it seems like the tool generating the pieces and looking for the pieces should keep to its own sandbox.

The command I used in qshell is:
/QIBM/ProdData/OS/WebServices/V1/client/bin/wsdl2ws.sh
-o/MKOESTER/RPG -lrpg -ms256 -ma5
-s/qsys.lib/MKOESTER.lib/wsrpg.srvpgm
QIBM/ProdData/OS/WebServices/V1/client/samples/getQuote/GetQuote.wsdl

(and I tried modifying the o- parameter to -o/qsys.lib/MKOESTER.lib/RPG as well as a few other variations. Same error.) I've confirmed with Navigator that the path to wsdl2ws.sh is correct, as is the path to GetQuote.wsdl.

We've been running 7.1 for a couple months here, and I'm told we're pretty current with PTF's, but no promises there. I've programmed in RPG for a few decades, but have no C++ experience and I'm new to QSH as well. I'd appreciate all insights anyone can offer.
Many thanks.
