That is what I need to know: What an I use to read the csv file as input in a java program to produce a report.
I switch to csv as you mentioned it's easier.HEEEEEEEEEEEEEEEEEEEEEEELLLPAnswer the following list where you have spent 30-40 hours a week for each peiod doing the following:
Have you been programming in java at least a year?
Have you programmed in another OO language such as C++, Smalltalk for at least a year?
Have you programmed in another procedural language such as Basic for at least two years?
Have you programmed in SQL (Oracle PSQL, MS SQL Server TSQL) for at least six months?
Have you used a database reports generator such as Crystal Reports for at least a year? (Again note that this means 30-40 hours a week.)
If the answer to all of the above is no then you are not going to accomplish any of the things that you have stated here "quckly".
If you answered yes to some of the above then that gives us a starting point. So post your answers.

How can one read a Excel File and Upload into Table using Pl/SQL Code.

How can one read a Excel File and Upload into Table using Pl/SQL Code.
1. Excel File is on My PC.
2. And I want to write a Stored Procedure or Package to do that.
3. DataBase is on Other Server. Client-Server Environment.
4. I am Using Toad or PlSql developer tool.

If you would like to create a package/procedure in order to solve this problem consider using the UTL_FILE in built package, here are a few steps to get you going:
1. Get your DBA to create directory object in oracle using the following command:
create directory TEST_DIR as ‘directory_path’;
Note: This directory is on the server.
2. Grant read,write on directory directory_object_name to username;
You can find out the directory_object_name value from dba_directories view if you are using the system user account.
3. Logon as the user as mentioned above.
Sample code read plain text file code, you can modify this code to suit your need (i.e. read a csv file)
function getData(p_filename in varchar2,
p_filepath in varchar2
) RETURN VARCHAR2 is
input_file utl_file.file_type;
--declare a buffer to read text data
input_buffer varchar2(4000);
begin
--using the UTL_FILE in built package
input_file := utl_file.fopen(p_filepath, p_filename, 'R');
utl_file.get_line(input_file, input_buffer);
--debug
--dbms_output.put_line(input_buffer);
utl_file.fclose(input_file);
--return data
return input_buffer;
end;
Hope this helps.

RETURN BOOLEAN
IS
n NUMBER;
BEGIN
n := TO_NUMBER(char_in);
RETURN TRUE;
EXCEPTION

you don't need to write ugly text file parsing codeParsing code isn't 'ugly' unless you don't know how to write it.I agree. However, in general people write lot of conditional statements and loops to handle different scenarios while processing text files.
what if the delimiter itself is part of your data?The answer to that is already defined in the CSV format.Agreed, but the complications (I gave one example only) you need to tackle unless you copy or use some existing CSV file parsing code. Moreover, why to bother so much when you have a free and open source sophisticated API.
I can think of a few reasons. At least with POI (not sure WRT to JExcel, but my guess is that this is still a valid statement), you have to build the document in memory. It is only written once all the various components have been specified in memory and then flushed to a stream. Therefore, large workbooks are problematic.
With a CSV, I have no such issues whatsoever. I can process row-by-row with very little memory overhead. For an application, say, generating reports via Excel, this can be a nontrivial issue.
I never said the approach: excel >> CSV >> process text is not a good option.

look in your "jexcelapi_2_5_9" package, in order to print you have to have something that understands the file strucuture of the object you want to print--ie knows what an excel file is.
