Adapter module to read excel file -java code required for PI 7.1

Question

Hi PI experts,
I am working on PI 7.1 SP 08.
I am trying to develope an adapter module to read excel file
http://wiki.sdn.sap.com/wiki/display/ABAP/AdapterModuleToReadExcelFilewithMultipleRowsandMultiple+Columns
but here in this wiki , given java code is for pi 7.0 and it is using jar file from PI 7.0
I tried with using corresponding PI 7.1 files
com.sap.aii.af.lib.mod.jar:
sap.comtcloggingjavaimpl.jar:
com.sap.aii.af.svc_api.jar:
com.sap.aii.af.cpa.svc_api.jar:
com.sap.aii.af.ms.ifc_api.jar:
jave program is not throwing any error in NWDS but After deploying file on server.
i am getting this errot in communication channel
2009-12-15 15:47:08 Information AO: Now calling the Convert Method to convert Excel to XML.

since i am not a JAVA expert so i am unable to resolve this error
if some one has already deployed this module for PI 7.1, then please provide me java code for PI 7.1

hi,
please try this:
obj = inputModuleData.getPrincipalData();
msg = (Message) obj;
amk = new MessageKey(msg.getMessageId(),msg.getMessageDirection());
XMLPayload xpld = msg.getDocument();
Workbook wb = Workbook.getWorkbook((InputStream) xpld.getInputStream());
xmldata ="<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n\n"+ "<ns0:"msgType" ""xmlns:ns0=\""nameSpace+"\">";
Cell[] cells ;
Cell[] cellNames ;
cellNames = wb.getSheet(0).getRow(0);
for(int j=1;j<wb.getSheet(0).getRows();j++)
xmldata = xmldata+"<Record>";
cells = wb.getSheet(0).getRow(j);
for(int i=0;i<wb.getSheet(0).getColumns();i++)
xmldata = xmldata"<"cellNames<i>.getContents()">"cells<i>.getContents()"</"cellNames<i>.getContents()+">";
xmldata = xmldata+"</Record>";
xmldata = xmldata"</ns0:"msgType+">"; 
wb.close();
byte byt[] = xmldata.getBytes();
xpld.setContent(byt);
inputModuleData.setPrincipalData(msg);
Thanks,
Mayank
