Requirement Description: - My web application has a
requirement of using a few rows of data from a .jsp page,
and Merge them into an existing Word template.

I have developed an application using JRun Application/web
server and Struts framework.  I invoke the winword.exe
file from my action class and pass the command line
switches as the document filename and the macro name in
order to do a word merge process.

Runtime rt = Runtime.getRuntime ();
String[] callAndArgs =
strWordExePath,strWordTempName,"/mMacroName"};
Process child = rt.exec(callAndArgs);
child.waitFor();

The placeholders are in the template Word document.  I
have built a Macro, which contains the script for invoking
the merge process with appropriate data source (.xls) file
and saves the merged document in a specific folder in the
server.  Code for macro is as follows:-

Sub AutoExec()
Dim sName As String
   
   Selection.HomeKey Unit:=wdStory
   sName = ActiveDocument.Name
   sName = Left(sName, Len(sName) - 9)
   sPath = ActiveDocument.Path
   
   ActiveDocument.MailMerge.OpenDataSource Name:= _
       sPath & "\" & sName & ".xls" _
       , ConfirmConversions:=False, ReadOnly:=False,
LinkToSource:=True, _
       AddToRecentFiles:=False, PasswordDocument:="",
PasswordTemplate:="", _
       WritePasswordDocument:="",
WritePasswordTemplate:="", Revert:=False, _
       Format:=wdOpenFormatAuto, Connection:="Entire
Spreadsheet", SQLStatement _
       :="", SQLStatement1:=""
   With ActiveDocument.MailMerge
       .Destination = wdSendToNewDocument
       .MailAsAttachment = False
       .MailAddressFieldName = ""
       .MailSubject = ""
       .SuppressBlankLines = True
       
       With .DataSource
           .FirstRecord = wdDefaultFirstRecord
           .LastRecord = wdDefaultLastRecord
       End With
       .Execute Pause:=True
   End With
  ActiveDocument.SaveAs FileName:=sPath & "\" & sName
& ".doc", FileFormat:= _
       wdFormatDocument, LockComments:=False,
Password:="", AddToRecentFiles:= _
       True, WritePassword:="",
ReadOnlyRecommended:=False, EmbedTrueTypeFonts:= _
       False, SaveNativePictureFormat:=False,
SaveFormsData:=False, _
       SaveAsAOCELetter:=False
   ActiveWindow.Close
   ActiveDocument.Save
   ActiveDocument.Close
   Application.Quit
End Sub

The word merge process works fine and I could see the
merged document in the concerned place, provided Jrun is
running as an application (Admin & Default Server would be
invoked from the Start button manually by a user every
time the server starts).

Problem: - When the above process is repeated by making
JRUN as a Service, the winword.exe hangs; instead of
continuing with the request and opening the word document
and running the macro for word merge process.
I can see winword.exe running in the Task Manager though.  
We tried capturing the exception but the control never
returns back and the process never gets complete.

Is there some conflict happening with the two Applications
(JRUN and MS Word 2000) when I start using JRUN as a
service? What exactly changes when I change the Jrun from
being an Application to exist as a service? Is there a
better approach to achieve the above-mentioned objective?

I would greatly appreciate any help in this regard.

Also thanking in advance for all your time and patience in
reading this.

Warm Regards,
Nitin
