How to read/write Excel sheets using java

Hello,
I have downloaded poi-2.5.1-all-bin and it has
poi-2.5.1-final-20040804 , poi-contrib-2.5.1-final-20040804, poi-scratchpad-2.5.1-final-20040804 jar Files
i am unable to configure POI which i have downloaded, when i do
import org.apache.poi.hssf.usermodel.HSSFSheet;
import org.apache.poi.hssf.usermodel.HSSFWorkbook;
it gives error while compilation saying cannot find Sheet class, Workbook class
should i use ant to build it or which jar file path should i specify in the classpath, because i have downloaded the POI package on to my desktop and included the specified the entire path of all the jar files in the classpath but still the same problem.
Please guide me.

Either it isn't in your class path or you are using the wrong names. Simple as that.
Just as a possibility since you didn't import a "Sheet" class but rather a "HSSFSheet" that certainly suggests something is wrong.

JoveIf I understand your question correctly you need to know the format of a .csv file for use in an Excel spreadsheet. A .csv file is a comma-delimited file so all that you need to do is write your data elements to the file with commas in between them. Having done something similar in the past, let me warn you that when Excel is reading your file, it uses some characters other than commas as field delimiters. for example, / : and ; are treated as commas. To defeat this, you will need to surround fields containing those characters in double quotes.
Hope that helps

How to lock excel sheets using java

hi,
i have developed a web page using JSP which has to open an excel sheet and display the databese information in it.
but the prblem is the excel sheet has to be locked such tht the clients accessing it can only read the data but not change it.
can it be done thru programming it in java ?
kindly help.

the excel file is client side and JSP is server side
so how can you access it?
in other words, your JSP IS NOT opening an excel file, it's only facilitating the upload
POI from Apache is what we use as well, and it will allow you access to the data AFTER the excel file is transfered to the server

How to read an excel sheet in java

hi all!
i want to read data from an excel sheet.could U plz send me the code from scratch.
thanks in advance

Look for jxl.jar (http://www.andykhan.com/jexcelapi/) or jexcel. Worked fine for me. And as for the code: see the example programs and documentation....
Sample:
     private ArrayList procesExcelFile(File file){
          logger.info("Processing XSL file ("+file.getAbsolutePath()+")");
          ArrayList result = new ArrayList();
          Hashtable xlsRow = null;
          int row;
          try{
               // Open sheet
               WorkbookSettings wbs = new WorkbookSettings();
               wbs.setInitialFileSize( (int) file.length());
               Workbook workbook = Workbook.getWorkbook(file,wbs);
               Sheet sheet = workbook.getSheet(0);
               // Init XML tags on 1st header
               this.readTagLine(sheet.getRow(0));
               // Read sheet row by row, skip first & empty rows
               for(row = 1; row < sheet.getRows(); row++){
                    xlsRow = this.convertRowToTable(sheet.getRow(row));
                    if(!xlsRow.isEmpty()){
                         result.add(xlsRow);
               logger.info("Processed XSL file, " + result.size() + " rows found (excl. header)");
          catch(IOException ioe){
               logger.error("Error reading XLS file", ioe);
               succes = "false";
          catch(BiffException be){
               logger.error("Could not get workbook from XLS file", be);
               succes = "false";
          catch(OutOfMemoryError oome){
               logger.fatal("Not enough memory for processing XLS file", oome);
               succes = "false";
          return result;
     }now gimme them Duke Dollars ;)

Can we create Multi Tabbed excel Sheet using Crystal Reports 2008

Hi,
We want to create a Crystal Report which will export the output as multiple Tab's ( we can use sub reports). Can we create a Multi Tabbed excel Sheet using Crystal Reports 2008 ( not Crystal reports Basic 2008). Please share any information/links on how to do that.
Also if it is not supported please let us know which version supports it.
Thanks,
Vasu

At least one of the 3rd-party Crystal Reports Desktop Scheduling tools listed at: http://www.kenhamady.com/bookmarks.html provides that functionality. It allows you to burst a single report so that each Group at level 1 becomes a separate tab. You can control the tab names (and tab colors) via fields/formulas inside the report.
You can also automate the process of exporting to (and also replacing or appending to) specified tabs inside existing workbooks.
