How do I produce an excel file using java code

How do i produce an excel file using java code.
If it is possible would ne one have ne source code as an example.

Dear All,
There are three ways for achiving excel operations using java including excel to xml etc.
1. There is a very effective tool available for this operation is "jexcel". You can find it at http://www.andykhan.com/jexcelapi/index.html
2. Jakarta site has provided a very good tool by name jakarta poifs. one can find at jakarta site.
3. One can develop a very effective tool by combining these above tools togather.
The operations that can be performed are read, write, convert etc for excel. The major attraction of Jexcel is excel to xml conversion.

hi,

el file use java.i can use .csv input the date to
excel.but i want to know how to format it.
thanks
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 modify an existing xml file from java code.

Hi
I have worked on creating a new xml file from java code using xmlbeans.But if i try to modify an already existing file using java code I am unable to get errorfree xmlfile.
For example if xml file(studlist.xml) is as below:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
Now suppose i have set name to victor using student.setName,
and set age to 20 using setAge from javacode,
the new xml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<StudentList xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="D:\kchaitanya\xmlprac1\abc\Studlist.xsd">
     <Student>
          <Name>ram</Name>
          <Age>27</Age>
     </Student>
<Student>
          <Name>sham</Name>
          <Age>26</Age>
     </Student>
</StudentList>
<Student>
          <Name>victor</Name>
          <Age>20</Age>
     </Student>
As observed this is not a valid xml file.But how can i modify without any errors?

I know it's an old post, but I found this while doing a google search for something else, and don't like to leave it un-aswered
Just in case anyone has a similar problem... In this case the new elements have been appended outside of the root element
What you need to do is first get the root element and then append the new children to that, there are several ways of getting the root element, which depend on what you want to do with the elements you get back here's a simple (incomplete) way.
// gets the root element of the specified file (code not shown)
Element rootElement= new SAXReader().read(file).getRootElement();Then just append the new elements as below (this is non-generic code and would need to be modified for your situation)
// write a new student element
Element student = document.createElement("Student"); // creates the new student
rootElement.appendChild(student); // ***appends it to the root element***
Element name = document.createElement("Name"); // creates the name element
name.appendChild(document.createTextNode("Fred")); // adds the name text to the name element
student.appendChild(name); // appends the name to the student
Element age= document.createElement("Age"); // creates the age element
age.appendChild(document.createTextNode("26")); // adds the age text to the age element
student.appendChild(age); // appends the name to the studentThen flush ya buffers or whatever and write the file

How can I open/save .xlsx file using java

Hi
I have a jsp whose contenttype of response is application/vnd.ms-excel.
When I am saving the file as .xlsx and opening from disk it displays error message.
How can I save and/or open the file as .xlsx?
Any advice will be appreciated.
Thanks

Checkout the Apache POI XSSF API or the OpenXML4J API's to create xlsx files and use a servlet to write it to the outputstream.
