Error while opening the EXCEL Sheet from a Report Program

Hi All,
I am getting an error saying 'SYLK: File Format is not valid' when my program is trying to open an excel sheet. I am using the function module WS_EXCEL to download it to excel sheet.
Following is the code:
Excel download

         c02(20),

a00_excel contains the data that is to be downloaded into the excel sheet. I used the same code in the other program it is working fine. If you see in the type declaration for C5 its 70 characters, i tried putting it as same as others to 20... still it doesnt work.

Generating Excell Sheet using Reports 9i

Hello,
I wanna know how can I do to generate one excell sheet using reports, without
use the option that4s generate text file using tab. I wanna know if someone have
example codes, or library4s.
Thanks,
Paulo Sergio

Here are some notes we created from the demo below. This works great for generating true formated excel output in 9i Reports using 9ias Rel2.
Notes from
http://otn.oracle.com/products/reports/htdocs/getstart/demonstrations/index.html
Output to Excel with Oracle9i Report
1.     Create an Excel template for the report. It should contain generic information such as title, logo and column headers
2.     Cretae a sample line of data in the spreadsheet
3.     Save the Excel spreadsheet as a Web page. File | Save As Web Page
4.     Open the Web page you just created in Reports Builder
5.     Double-click on Web Source node to display the HTML code for the Excel spreadsheet
6.     Note how Excel generated HTML and XML code for the spreadsheet you created. Reports Builder also adds its own JSP tags
7.     Add the Data Source An SQL Query
8.     Modify the Web Source. Now that youve written the query, you can modify the Web source to tell Reports Builder to display your report in Excel.
9.     Click on the Web Source icon in the toolbar.
10.     To force the browser to open MS Excel it is necessary to change the HTTP Content Type to a specific MIME Type:
application/vnd.ms-excel
     Insert the following line immediately before the <rw:report id=report> tag
          <%@ page contentType=application/vnd.ms-excel %>
     (This is a standard JSP directive to set a MIME Type (Content Type) )
11.     To respect Excel format, you should delete the blank lines above the <html> tag.
12.     Now, use Oracle 9i Reports JSP tags to add the data retrieved by your SQL Query to the report.
13.     Search for the sample line of data you added to your Excel spreadsheet
14.     Each line is saved as an HTML Table Row tag ( <tr> ).
15.     Each column is mapped as an HTML Table Data tag ( <td> ).
16.     Using Reports JSP Tags, add a Reports repeating frame tag to loop around the Data Model group.
17.     To help, show the Object navigator next to the Web Source Window. All group information is now visible in the Object Navigator
18.     Enclose the sample line of code in the Web source with the Reports9i JSP repeating tag.
Use from menu Insert | Repeating Frame at beginning of sample
Move the closing repeating tag after the </tr> tag.
Start of the repeating tag would be
<rw:foreach id=foreach src=>
Ending of the repeating frame would be
</rw:foreach>
19.     In the opening of the repeating tag (<for each>), add the name of the group the tags enclose. JSP custom tags require a unique identifier.
For example: <rw:foreach id=gEmpNoId src=G_EMPNO>
20.     Now, map the cells of the Excel spreadsheet to the corresponding field from your data model.
Select on the data value. From menu select Insert | Field. The source of the tag is the name of the field in the query.
21.     Repeat the operation for each field of the report. Note: do not forget to specify a unique identifier for each field.
22.     The code now contains a repeating frame. You have also mapped each cell in the Excel spreadsheet to the corresponding field in the data model
23.     Save the report as a Reports JSP. You can test the report using the Run Web Layout icon in the toolbar
24.     The execution of a Web Layout report from Reports Builder creates a temporary HTML file and launches the browser. The browser does not launch Excel because the document is saved as an HTML file. To launch Excel from the browser you need to test it from Reports Server.
25.     In order to have the report appear inside Excel, you need to execute it with the Reports Server under OC4J. To do this you need to:
First, start an OC4J instance from Oracle 9iDS see How to Execute Reports Services from Oracle 9iDS on OTN. Then, copy the JSP to a directory. For example: $IDS_HOME/reports/j2ee/reports_ids/web/test
26.     Enter the URL to execute the jsp. The JSP is executed from an OC4J instance.
http://reports9iTestServer:8888/reports/test/ListOfEmployees.jsp?userid=scott/tiger@ora901
27. The browser launches Microsoft Excel and displays the data from your report.

Excel sheet listing

Hi!, I'm writing an application, where in I need to list all the sheets in an Excel file. I'm able to read data from a single excel sheet. I need to list all the existing sheets in an Excel file. I would like to know if there is any process using Java API to list all the availablie sheets in an Excel file.
Thanks in advance
Ravi.

Hi!, I'm writing an application, where in I need to

Thanks in advance
Ravi.Ravi:
I use the following code to obtain the number and names of
sheets from an Excel file:
Connection con = null;
con = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Excel Driver (*.xls)};DBQ=d:\\weblogic\\temp\\TestExcelData.xls;DriverID=22;READONLY=true","","");
if (con != null) {
System.out.println(" Connection successfully made \n " + con.toString());
DatabaseMetaData dbMetaData = null;
dbMetaData = con.getMetaData();
if (dbMetaData == null) {
System.out.println(" Unable to obtain database metadata ");
System.exit(0);
ResultSet rsTables = dbMetaData.getTables(null, null, null, null);
while (rsTables.next()) {
System.out.println(" name " + rsTables.getString("TABLE_NAME"));
System.out.println(" Tables are selectable : " +
dbMetaData.allTablesAreSelectable());
ResultSet rsColumns = dbMetaData.getColumns(null, null, "Sheet1%", null);
while (rsColumns.next()) {
System.out.println(" table " + rsColumns.getString("TABLE_NAME") +
" column " + rsColumns.getString("COLUMN_NAME") +
" datatype " + rsColumns.getString("DATA_TYPE"));
String sql = "select roomrate1 from Sheet1$;";
PreparedStatement pstmt = con.prepareStatement(sql);
ResultSet rs = pstmt.executeQuery();
The result from getColumns shows that a table name is Sheet1$,
and column name is roomrate1, but trying to execute the
select statement fails with the exception:
java.sql.SQLException: [Microsoft][ODBC Excel Driver] Syntax error in FROM clause.
I understand you have been able to read data from a work sheet.
Can you tell me what I am doing wrong or share a code snippet as
an example? Thanks.

Generate Excel Sheet using Servlet

Hi all,
I have a HTML page with some fields and a submit button. This HTML page is calling a servlet. When this servlet is called from this HTML, I want the servlet to take the values in the fields of the HTML page and create an Excel Sheet with those values.
Thanks,
Anirvan

Write all the details into an jsp/html as usual...
just change the content type of the response of the servlet before you redirect.
res.setContentType("application/vnd.ms-excel");
res.setHeader("Content-Disposition", "attachment; filename=\"fileName.xls\"");

Generating Excel Sheet from Reports ......

Hi,
I want to generate reports both in Oracle Reports 6.0, as well
as in Microsoft Excel. The simplest solution I thought was to
generate the Oracle Report first and then, give a button on the
report, which when pressed, can scan the data in the generated
report and write it into an Excel file. The writing part to
Excel file, I can do by using the OLE2 automation. I am not able
to find a way to read the data in the generated report
programatically. Is this possible and if yes, then can anyone
suggest me a way to do this. Is there an alternate solution to
this problem.
regards,
Abhilash

Hi ,
Modified your code .
public void generate(IPortalComponentRequest request) throws Exception {
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
HSSFRow row = sheet.createRow(3);
HSSFCell cell = row.createCell((short)0);
HSSFCellStyle cs1 = wb.createCellStyle();

Help required on deleting temporary files through program

I could able to create, write and read from a temporary file. But I am unable to delete it. Can anyone help me to fix this. Here is the code.
Thanks in advance.
import java.io.*;
public class Test {
   File file1 = new File("C:\\temp");
   public static void main(String[] args)throws Exception {
       Test t = new Test();
        t.createTempFiles();
        t.read();
        t.delete();
    public void createTempFiles(){
        try{
            File temp = File .createTempFile( "TempFileName", ".tmp", new File ( "C:\\temp" ) );
            BufferedWriter bufferWriter = new BufferedWriter(new FileWriter(temp));
            bufferWriter.write("Temporary File");
            bufferWriter.close();
         catch(Exception exp){
            exp.printStackTrace();
   public void read()throws Exception{
       File file[] = file1.listFiles();
        for(File obj: file){
        BufferedReader reader = new BufferedReader(new FileReader(obj);
        System.out.println(reader.readLine());
   public void delete(){
      File file[] = file1.listFiles();
      for(File fl : file){
         System.out.println(fl.delete());
}

I think you are unable to delete because you never close the reader, so the operating system reports the file is still in use.

Excel sheet generation through RFC call from a BSP application

Hi,
I am calling a RFC FM ( in R3) in Event handler 'OnInputProcessing' of a BSP application in a SRM server.
That function submits a report program which geneates a excel sheet using download FM . Excel sheet is not getting generated.
But when i am calling this RFC FM (in R3) from a report program ( in srm server)
this is generating an ecel sheet.
I want to have call RFC from BSP application.
I tried the way of submit a program ( which contains RFC call) from BSP application ,but it is also not generating excel sheet.
My ultimate AIM is to generate excel sheet by trigerring CALL or submit from BSP
application.
can any one propose solution for it.
Useful answers will be rewarded.

Hi,
Which FM is it. I guess that the download generated is a SAP gui oriented solution, which will never work in a web environment

thanks in advance

The problem here is, you have setted the content type as excel sheet and you are writing some String content into the output stream. when excel tries to read the String content it will surely throw some error. Lot of excel APIs are available in the market to generate excel sheets.
you can find one in the below URL.
