Cfx_ExcelQuery

Does anyone have any experience using the cfx_ExcelQuery
custom tag which is part of the OpenXCF project?
I installed the tag and wrote a simple program to test the
functionality.
If I call the custom tag w/ no arguments
<cfx_ExcelQuery> CF throws an error indicating missing
attributes, well & good.
But when I pass the attributes - I get a JRun Servlet Error
500 org/apache/poi/poifs/filesystem/POIFSFileSystem
org/apache/poi/poifs/filesystem/POIFSFileSystem
The error text appears to be coming from within the tag
itself as I am running on a Windows server and what appears to be a
directory path isn't related to anything on that server.
I originally tried passing the entire directory path to the
file I'm trying to read, then moved that file to the same directory
containing the test program, but same results either way.
Thanks in advance for any insights,
Ken

Cfx_ExcelQuery: specify sheet?

I installed the cfx_ExcelQuery custom tag which is part of
the OpenXCF project and with the help of this forum have been able
to successfully read data from an Excel file.
Does anyone know if there is a way to specify a specific
worksheet to read by name? By trial and error I discovered that a
specific sheet can be accessed by passing an index number
(sheet="0") but haven't been able to get it to take a sheet name.
If not - no big deal, it's just that the program I'm working
on originally used ODBC and required the user to specify the name
of the sheet with the pertinent data.
Thanks in advance,
Ken

The tag only accepts a number. You could use POI to get the
sheet number.
<cfscript>
fis = createObject("java",
"java.io.FileInputStream").init("c:\yourFile.xls");
wb = createObject("java",
"org.apache.poi.hssf.usermodel.HSSFWorkbook").init(fis);
sheetNumber = wb.getSheetIndex("Sheet1");
fis.close();
</cfscript>
<cfx_ExcelQuery action="read" file="c:\yourFile.xls"
sheet="#sheetNumber#" variable="myQuery" />

POI-Apache ERR

What is the solution people ?
The file exist in c drive with 2 sheets in excel file called
"As-Built and Design"

What happens when you dump the value of sheetNumber before
you call your CFX tag? Also, if the excel file is called "As-Built
and Design", why are you trying to open template.xls? If
sheetNumber is set to a java NULL value, that could explain some
funky behavior by CF.

Apache POI

Hi,
I have installed cfx_excelQuery [ into web-inf\lib\ ], and
registered the tag then extracted the zip[ poi-2.5.1-final-20040804
] into \web-inf\lib\ ...Then restarted the CF service ..still I am
getting this...I am using CF server 6,1,0,63958 on windows 2000
server..
Object Instantiation Exception.
Class not found: org.apache.poi.hssf.usermodel.HSSFWorkbook
The error occurred in D:\CFusionMX\wwwroot\1.cfm: line 12
10 : <cfscript>
11 : fis = createObject("java",
"java.io.FileInputStream").init("c:\template.xls");
12 : wb = createObject("java",
"org.apache.poi.hssf.usermodel.HSSFWorkbook").init(fis);
13 : sheetNumber = wb.getSheetIndex("Sheet1");
14 : fis.close();

poi-2.5.1-final-20040804 is usually distributed as a jar. Put
this jar in cfusionmx/lib or on j2ee version put in
WEB-INF/cfusion/lib and restart. No need to expand the jar
contents. Alternately put the jar in any directory outside the cfmx
structure and specify the path in the jvm.config classpath
including the filename.

Installing java custom tag

I'm trying to install a custom tag written in java
(cfx_ExcelQuery) and am not having any success.
The tag was in a .jar file which I downloaded to the server
and extracted to the /classes subdirectory. The actual .class file
ended up in a subdirectory several levels below.
I registered the tag as ExcelQuery and wrote a test program
to call the tag according to the specs.
I got a CF error indicating the tag didn't exist until I
added the directory path containing the .class file (the exact
subdirectory). Now I get an internal server error instead (progress
I guess).
I have no experience installing/using java custom tags so I
may be missing something that would be obvious to someone else.
If anyone has any ideas please let me know.
Thanks,
Ken

I got this error:

Hi em,
I tested your cfscript with poi-2.5.1-final-20040804.jar
installed as follows:
in cfusionmx\lib - code works
in cfusionmx and added to classpath in jvm.config - code
works
in cfusionmx\wwwroot\WEB-INF\lib - code works
I followed up with expanding the jar into WEB-INF\lib and the
code failed, just as with yours. So, install the jar without
expanding its contents and you should be good to go.
