Apache Poi Excel Question

If I use Apacha Poi to create an xls on a machine that doesn't have excel, can I still read the values using Apache Poi HSSF of the create xls?

yes, POI is independent of Excel being installed.

Using Apache POI 3.2 to create hyperlinks in Excel

Hello,
I am new to Java.
I have written a program that accesses Excel with the Apache POI version 3.2.
All seems to work until I tried to insert a Hyperlink to a file on the local drive.
I followed the quick start guide from Apache POI.
It provides the following code but Java does not appear to find the "createHelper".
//link to a file in the current directory
cell = sheet.createRow(1).createCell((short)0);
cell.setCellValue("File Link");
link = createHelper.createHyperlink(Hyperlink.LINK_FILE);
link.setAddress("link1.xls");
cell.setHyperlink(link);
cell.setCellStyle(hlink_style);
Any ideas on how to insert a Hyperlink into Excel would be appreciated.
Thanks
Chris

This seems to be a class in 3.5 beta jar file. Try downloading and using the 3.5 beta

Excel File Management Apache POI HSSF vs. jxl jar

I've been reviewing Java technologies for managing Excel files, and I'm a little confused about the differences between Apache's POI HSSF implementation and JExcelApi, and utimately what technology it makes sense to use.
They are both open source, although POI is backed by Apache, where JExcelApi seems to be open source developed by Andy Khan. It seem Apache has a little more weight, therefore may be a better option.
Can someone who has exposure to these technologies please provide me with some insight.
Thanks.

Hi
Thanks for your reply,
Now I hav used an alternate approach of using Apache POI.
But.......
I have created simple table in jsp and set content type to
<%@ page contentType="application/vnd.ms-excel" %>
when i navigate to this jsp it is getting displayed in excel format.
I wish if user clicks on to navigate for this jsp, he must get an option to either open, save or cancel the jsp.
Then on selecting save a dialogue gets appeared where he can select path and file name.
Please comment.
Thanks.

Questions about Apache POI

If you have experience with Apache POI, please help me!
(1) HWPF is in POI API documentation (javadoc), but I didn't find the classes in the jar (jakarta-poi-1.5.1-final-20020615.jar). Did I miss something?
(2) Is HDF substituting HWPF?
(3) Is it possible to create Word file with HWPF or HDF? If so, is it possible to create tables in the Word file?
Thanks! I understand there has been lots of discussion of this topic, but I've not been able to find anything substantial, and have to ask questions here again.

The HWPF is in early stages of developement, therefore it is not included into the final distribution. Try poi-scratchpad-2.5.1-final-20040804.jar. Here you will find the classes you need
About creating word documents, it can be done using HWPF, but i suggest you to try itext which will generate rtf (http://www.lowagie.com/iText/docs.html). It's quite simple to create tables.

Hi,
I am dealing with the similer problem but the same error. I am using the latest version of POI 3.0.1 and trying to read the cells which have auto formating enabled for date. I am getting the same error. Please let me know if you come across any solution to read the formatted cells using POI.
Thanks in advance!

Can I process Excel BIFF5 files, or simply abandon Apache POI?

To the experienced:
I am totally new to processing Microsoft Excel files using Java, and embarked on Apache POI. Now it seems I could be completely out of luck because of the Excel files I am to process.
Now looking back, I realize that what I did with the Excel file I first received (a .xls file) was opening it in Excel 2007 and clicked the Save button. And it was all OK learning POI by processing that file. Now after all the work I have done with that file, I trashed it and got a copy of the original Excel file - as is, without first loading it in Excel 2007 and saving it - and run my java program on it. And I got the following error message talking about BIFF5 and BIFF8:
C:\Oracle\Middleware\jdk160_18\bin\javaw.exe -client -classpath
C:\apps11113\JavaExercise\.adf;C:\apps11113\JavaExercise\Basic\classes;C:\java_lib\poi-3.7\poi-3.7-20101029.jar
-Djavax.net.ssl.trustStore=C:\Oracle\Middleware\wlserver_10.3\server\lib\DemoTrust.jks learnjava.ExcelTest2
Exception in thread "main" org.apache.poi.hssf.OldExcelFormatException: The supplied spreadsheet seems to be Excel 5.0/7.0 (BIFF5) format.
POI only supports BIFF8 format (from Excel versions 97/2000/XP/2003)
My program, when put into production, will run on schedule and unattended, and will have to process the file as is. Am I out of luck and have to look for some other APIs that support BIFF5? Are there such APIs?
Many thanks for helping!

Are there such APIs?I'm pretty sure that OpenOffice will. One test you could do is try to open your 5.0 file in OpenOffice, save it as an Excel 97/2000 file (+don't+ delete your original :-) ) and check to make sure that everything is working as expected, and then see if your POI program can process that.
If it works, you could try downloading the OpenOffice SDK. It's also possible that something like jodConverter could do the job for you (it looks a lot easier to use), but you'd need to check their website.

Pros and cons of jxl api and apache poi of manipulating the excel sheet.

i want a list of pros and cons of jxl api and apache poi of manipulating the excel sheet.
also i need to know which one is better jxl or apache poi.

Hi Ricardo_Lorenzo,
Whether to go for Multiserver instances or Single server, is totally a user requirement based decison. If a user has Single website, or multiple websites (of the same nature, in terms of functionality), usually the part of same domain, then they would go for Single sever installation. One single instance will handle the requests from all the websites (if there are multiple). There would not be a clustering/failover setup within ColdFusion and can use the ColdFusion Standard or Enterprise version.
On the other hand, if a user has multiple websites, all with different functionality and have multiple applications (may or may not) running, then they can go for Multiserver installation. Each website can be configured with individual instances. Clustering can be done within ColdFusion if needed. One would need an Enterprise license of ColdFusion for the same.
Hope this helps.

Anit Kumar

How to read .XLSX files using org.apache.poi.ss.usermodel.* classes

Hello,
I want to read in excel files to a JTable. I was able to read in .xls files, but have problems reading .xlsx files. Maybe there is something i need to add to the following code:
FileInputStream iStream = new FileInputStream(newFile);
POIFSFileSystem fs = new POIFSFileSystem(iStream);
Workbook wb1 = WorkbookFactory.create(fs);
Sheet sheet = wb1.getSheetAt(0);       // get the first sheet data
// Iterate over each row in the sheet
Iterator rows = sheet.rowIterator();
   while(rows.hasNext()) {
      Row row = (Row) rows.next();
      .............The compiler is complaining about the 3rd line: Workbook wb1 = WorkbookFactory.create(fs);
Thanks.

@ejp:
I quite agree with you. It's a runtime exception -
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)I've tried searching before coming here to ask. HSSF processes .xls files only, XSSF processes .xlsx files only while SS is supposed to read both .xls and .xlsx files. Maybe there's anyone that has used it before who can help out.
Thanks

Apache POI Compile Error

So I'm trying to use the Apache POI to write Excel sheets. I downloaded the latest version (3.8) and added it to my project in JDeveloper. I can't get any examples to work. The line:
Workbook wb = new HSSFWorkbook();
give me this error:
Error(22,13): Iterable not found in interface org.apache.poi.ss.usermodel.Row in class org.apache.poi.hssf.usermodel.HSSFWorkbook in class test.PoiWriteExcelFile
Google is no help. Seems like I'm missing something basic. PLEASE HELP!

Which version of JDeveloper you are using
Validate if you are using J2SE older than 1.5

Anyone have a suggestion?

Apache POI Upgrade issue

Hi,
I am working for an ADF application and here we have used POI 2.5 JAR file for the excel reading.
Now we are upgrading to poi-3.8-beta3 VERSION to handle both xls and xlsx versions. But we are getting the following error when trying to execute the below code snippet.
POIFSFileSystem fileSystem = new POIFSFileSystem(inputStream);
HSSFWorkbook workBook = new HSSFWorkbook(fileSystem);
Error Message:
org.apache.poi.poifs.filesystem.OfficeXmlFileException: The supplied data appears to be in the Office 2007+ XML. You are calling the part of POI that deals with OLE2 Office Documents. You need to call a different part of POI to process this data (eg XSSF instead of HSSF)
Is there way to fix this issue without making any code change so that it should support both the excel versions. Please suggest.
Thanks,
Manasa

Manasa,
Well, being that the error message says "you need to use a different part of the API," it appears that you need to make a code change.
This is also not the POI forum/mailing list, so it would be appropriate for you to ask there, not on the JDeveloper/ADF forum.
Also, if you'd have searched this forum, you'd have found out that other people have made the same mistake of asking on the wrong forum and gotten an answer.
Finally, if you Google for "org.apache.poi.poifs.filesystem.OfficeXmlFileException" you'd find even more information

When you "pull" a formula down a column, Excel automatically changes the formula for each row, but because you've fixed both the column AND the row ($A$1), it'll be the same in all cases.
I don't know if POI allows that sort of "auto-generate" for formulas, but if so try something like $A1 instead; otherwise I suspect you'll need a different formula for each row.
