Jakarta POI

The problem is that when i open the XLS file that I create using POI the DATE Cells are not formatted as DATE Cells and the code is well.
It's
private void llenarFila(ResultSet rs, HSSFRow row, HSSFWorkbook wb) throws SQLException {
                ResultSetMetaData rsmd = rs.getMetaData();
                //DateFormat df = DateFormat.getDateInstance();
                SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
                HSSFDataFormat format = wb.createDataFormat();
                SimpleDateFormat formatter2 = new SimpleDateFormat("dd/MM/yyyy", new Locale("es"));
                //DateFormat formatter2 = DateFormat.getInstance();
                for(int i = 1 ; i <= rsmd.getColumnCount() ; i++) {
                        int columnDataType = rsmd.getColumnType(i);
                        System.out.println(columnDataType);
                        HSSFCell cell = row.createCell((short) (i-1));                                                                                                                         if(columnDataType == 93) { // java.sql.Types.DATE y oracle.jdbc.driver.OracleTypes.DATE son 91 y no funcionan... de la basde devuelve 93 para DATE
                                try {
                                        Object obj = rs.getObject(i);
                                        if(obj != null) {
                                                String dateString = ((Object)rs.getObject(i)).toString();
                                                java.util.Date date1 = formatter.parse(dateString);
                                                String newDateString = formatter2.format(date1);
                                                System.out.println(date1.toString());
                                                java.util.Date date = formatter2.parse(newDateString);
                                                System.out.println(date.toString());
                                                HSSFCellStyle cellStyle = wb.createCellStyle();
                                                cellStyle.setDataFormat(format.getFormat("dd/mm/yyyy"));
                                                cell.setCellType(HSSFCell.CELL_TYPE_NUMERIC);
                                                cell.setCellStyle(cellStyle);
                                                cell.setCellValue(date);
//.... the rest...
}Any ideas ? Thanks a lot. This is going me crazy since yesterdya.

How to read .doc files using jakarta POI api......

Hi all,
I've googled a lot on reading the file contents of an MS word file. I couldn't get a solution yet. Can you please give some sample codes for using the POI api for extracting only the text contents from an MS word file.
Thanks and Regards,

whenever i click the folders, it's taking
to the internal folders. but there's no
option to download the whole package.Thats because you're looking at a tool which displays the contents of an svn repository through a web site.
What you need is a subversion client (the repository is a subversion repository).
There are several easy to use clients available:
Here's two:
1) subclipse: If you use eclipse. Dammed great tool IMHO. http://subclipse.tigris.org/
2) tortoise svn http://tortoisesvn.tigris.org/
When you've got a client, you'll need to give it a repository URL from which to check out.
For the POI project, that URL is http://svn.apache.org/repos/asf/jakarta/poi/trunk/

Where do I download jakarta-poi-1.5.0-FINAL-20020506.jar from ???
Can anybody help me ???

Hi Friends,
I'm also on the same track. I download the jw-0332-poi from Resources of http://www.javaworld.com/javaworld/jw-03-2004/jw-0322-poi.html
I compile CreateXL.java & ReadXL.java files & got compilation errors like:
"cannot resoleve symbol class HSSFWorkbook
"Cannot reslove symbol class HSSFSheet"
and more error for HSSF package from org.apache.poi
To solve this I download "poi-bin-3.0-Final-20070503.zip" from http://www.apache.org/dist/jakarta/poi/release/bin/
and poi-src-3.0.1-FINAL-20070705.zip files fromApache download mirrors. i put it in classpath & then compile but still I got the same error.
I didn't find jakarta-poi-1.5.0-FINAL-20020506.jar on http://www.apache.org/dist/jakarta/poi/release/bin/
From where should I get the jakarta-poi-1.5.0-FINAL-20020506.jar ?
I would appreciate your help for this topic.

Apache Jakarta JETSPEED and ApEx (Authentication)

Hi everybody!
I would like to integrate ApEx into the Apache Jakarta Java Framework Jetspeed. Therefore I would like to use the usermanagement and and session handling of this framework (authentication in Jespeed is also used for ApEx - no new login necessary).
Does anyone have an idea, how this can be setup in ApEx/Jetspeed? Or does anyone have a ready solution for this question?
Thanks in advance and best regards,
Christian

ApEx is not JSR168 compliant - but that doesn't mean to someone couldn't come up with a way to plug some ApEx content into a JSR168 portlet. When you're doing this kind of thing there are lots of considerations.
Like:
what is the content?
who needs to be able to see it?
who needs to update it, if anyone?
what are the security implications?
One very simplistic approach that could be used to get ApEx content into the Jetspeed portal is to use a standard HTML portlet with an iframe embedded in it that points over to the ApEx content. Obviously, this doesn't include any kind of authentication to ApEx.
You'd probably have to look into some of the SSO stuff that's buit into ApEx.

Jakarta POI Excel97-2000 (Excel 2003?)

Hi All
I need to read data from Excel 2003 spreadsheet using my java program.
I looked at Jakarta POI, and JDBC-ODBC bridge options.
POI says Excel97-2000
Creating system DSN does not show Excel 2003 options. It shows Excel97-2000, Excel 3.0 etc
My environment is Windows XP 2002.
Can I read Excel 2003 documents using POI?
If I deploy this program on a machine which has earlier versions of excel on it will it be able to read.
I just have plain text in excel spreadsheet.
Please let me know.
Thanks
bib

Hard to answer this question definitively because it very much depends upon exactly what is in the file. If you have saved a complex, formatted document that makes extensive use of features that were introduced into Excel for version 2003 then you will face problems. If the file contains simply plain text, then you should be fine. Most of the API authors base their product on an earlier version of the BIFF8 format to ensure compatibility with as wide a range of Excel versions as possible. That is why they all mention that the API will handle files that are based upon a specific version of Excel. Hopefully, you will be fine distributing the application onto machines that run earlier versions of Excel.
By the way, have you also considered JExcel? It handles a few things differently to HSSF (POI) and you may prefer the way it approaches parsing an Excel spreadsheet file and exposing it's contents.

Jakart POI HWPF

I am trying to create/edit a Word document using a pure Java approach. So far the most succesful approach has been using JIntegra (which claims that can do everything that you can do with VBA). However, JIntegra has a commercial license. So, I am trying to look into Jakarta POI which has been in development for ever. It seems to have some functionality that I can use as far as creating/editing word documents but one big fuctionality that I need is inserting images, which so far I haven't been able to figure out.
Any body out there has been succesful at implementing an application using POI HWPF, if so, I will really appreciate your input.
Regards,
Paul

I have the same problem. Right now, we're using libraries from the JACOB project
(http://danadler.com/jacob/), but I haven't been able to find any really helpful documentation. If anybody
has another solution, I'd be thrilled to hear about it also.

Jakarta --POI doubt

I am using a servlet to create an xls file using Jakarta-POI.Rt now i am saving the file to the server,then copy to the client s/m which accesses the servlet
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("export");
FileOutputStream fileOut = new FileOutputStream("test.xls");
wb.write(fileOut);
fileOut.close();
This code directly saves the file to the server.
Can i write the workbook directly to client's s/m using any buffering?
bcoz my boss told me this will create sme security issues .....
Anybody plz help me..
Thanks in advance

Don't a different stream, like the servlets output stream?!

Problems in Using Jakarta POI in Jserv- NoClassDefFound

Hi,
I'm trying to deploy an application on Jserv which used the Jakarta's POI API. I placed the Jar file in the server folders and specified the same path in the file Jserv.properties.
But then when trying to access that folder it gives the error NoClassDefFound for the poi's packages meaning its not picking up the classes under this jar.
I restarted the Jserv several times after mentioning the path.
Can anybody help me on this in pointing out wat i have missed here.
Thanks in advance,
Vijay

hello,
i'm also having problems using poi. I've copied the poi jar to tomcat/lib and also to the lib directory of the systems jdk. I've done the same with the commoms-logging.jar.
Within a jsp is import these things:
<code>
<%@ page
     buffer="128"
     import="java.util.*,
          org.apache.poi.hssf.usermodel.*,
          org.apache.poi.hssf.util.*"
%>
</code>
But when calling the url of the page i get:
Package org.apache.poi.hssf.usermodel not found in import.
Why, it is in the import? Whats wrong there?
Thank you,
Hava a nice day,
Nico

5.POI do not provide password capability for the spreadsheet.
6.POI consumes lot of heap memory when we write data to excel sheet which causes outofmemory error.JExcelAPI also does not offer support for passwording a spreadsheet. Even if it did, breaking the password on a spreadsheet only takes seconds with the right tool.
JExcelAPI, until recent versions, has been known to consume memory as well. Changes have been made to the code which greatly improves it's memory usage.
Having used JExcelAPI for nearly 3 years now I would highly recommend using it. Here are some links to help:

The forum is active as well, myself and others are always there to help.

JavaDB / Apache Derby equivalent to the SQL Server IsNull and Oracle nvl

Firstly, if questions for JavaDB are supposted to go somewhere else, sorry for posting in the JDBC section, but I couldn't find a specific section for it.
I'm trying to add support for Apache Derby to a piece of software that already has support for Oracle, SQL Server and MySQL. There is a lot of DB specific coding involved to get the best performance possible. Several of these queries involve checking to see if a nested query returns a value and substituting 0 if no rows are returned.
In Oracle the function is called: nvl
In SQL Server the function is called: IsNull
In MySQL the function is called: IfNull
I can't find an equivalent for Derby. Does one exist?
