I have a CFC I wrote that has many spool file functions in it, one of
which reads a spool file and returns it as text. Well, my issue is that
the byte reader is incredibly slow for 50 - 100+ page documents. I see
a few other stream file read methods in the java api, but I cannot
figure out how to invoke them properly. Has anyone else done this
before, or have a function that uses Java to read a spool file? Here is
my function to read currently (which is way too slow).
<cffunction name="getSpoolFile" returntype="any" hint="Returns a
formatted spool file from the AS400 - required the getSpoolFileList
function be executed first!">
<cfargument name="index" required="true" type="numeric"
hint="Index of the spool file to be retrieved">
<cfset var spoolData = '' />
<cfset var buffer = '' />
<!---// Set my print parameters based on incoming
arguments.format //--->
<cfset
PrintParameterList.setParameter(PrintObject.ATTR_WORKSTATION_CUST_OBJECT
, "/QSYS.LIB/QWPDEFAULT.WSCST") />
<cfset
PrintParameterList.setParameter(PrintObject.ATTR_MFGTYPE, "*WSCST") />
<!---// Load spool file into memory as an object //--->
<cfset spoolObj =
SpooledFileList.getObject(numberFormat(arguments.index)) />
<!---// Return a transformed input stream //--->
<cfset spoolFile =
spoolObj.getTransformedInputStream(PrintParameterList) />
<cfset savechar = 1 />
<cfloop condition="savechar neq -1">
<!---// Read one byte from our file //--->
<cfset savechar = spoolFile.read() />
<cfif savechar eq -1>
<cfbreak>
</cfif>
<!---// This will format the save file to be
printed properly from the web //--->
<cfswitch expression="#savechar#">
<cfcase value="32">
<cfset buffer = buffer & ' ' />
</cfcase>
<cfcase value="12">
<cfset buffer = buffer & '<p
style="page-break-after: always"></p>' />
</cfcase>
<cfdefaultcase>
<cfset buffer = buffer &
chr(savechar) />
</cfdefaultcase>
</cfswitch>
</cfloop>
<cfset spoolData = buffer />
<cfreturn spoolData />
</cffunction>
