HI Reji,

Ant is installed in
C:\work\ant\apache-ant-1.7.1

POI  is unzipped into
C:\work\poi-3.5-FINAL

In step 2 below, what is the top level directory? Is this the top level
directory where POI is installed? In my case would that be
C:\work\poi-3.5-FINAL?

Yes.

I do not see a build.xml file in the C:\work\poi-3.5-FINAL directory or am
I looking in the wrong place?

It should be there. Did you download the source distribution (poi- src-3.5-FINAL-20090928.zip) from http://poi.apache.org/download.html?

Here is what I see in "the top level directory"

lightning:POI-3.5-FINAL dave$ ls -1

build
build.xml

Hi,

I just rewrote this page: http://poi.apache.org/howtobuild.html  You
probably read this already.

Here is what you need to do.

(1) Make sure ant is in your path:

PATH= ... /apache-ant-1.7.1/bin

(2) While in the same top level directory with the file "build.xml"
type in this at command:

ant compile jar

(3) Find the jar files in build/dist/.

build/dist/poi-3.5-FINAL-20091123.jar

Regards,
Dave

I have a need to read an excel file from a java application. Here is
what I
have done so far.
I have unzipped the poi-3.5.-FINAL zip file and downloaded the 1.7
version
of ANT

My java runtime version "1.6.0_14

I added the jar file poi-3.5-FINAL-20090928.jar file to my project
and run
some some test code in a java application. I get the following
message.

Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/apache/poi/poifs/filesystem/POIFSFileSystem (Unsupported
major.minor
version 49.0)

Is this because I need to rebuild the code using my jdk 1.6. This is
where I
am not sure how to proceed. I am a beginner in using ANT, so some
detailed
instructions would really help. Thanks in advance for your help.
