Anyone know if it is possible?
And got any sample code for this?
Or any other java API that can do this?
The Office 2007 format is based on XML and so can probably be written to using XML tools. However there is this library which claims to be able to write DocX format word documents.
The only other alternative is to use a Java-COM Bridge and use COM to manipulate word. This is probably not a good idea though - I would suggest finding a simpler way.
For example, Word can easily read RTF documents and you can generate .rtf documents from within Java. You don't have to use the Microsoft Word format!
As others have said POI isn't going to allow you to do anything really fancy - plus it doesn't support Office 2007+ formats. Treating MS Word as a component that provides this type of functionality via COM is most likely the best approach here (unless you are running on a non-Windows OS or just can't guarantee that Word will be installed on the machine).
If you do go the COM route, I recommend that you look into the JACOB project. You do need to be somewhat familiar with COM (which has a very steep learning curve), but the library works quite well and is easier than trying to do it in native code with a JNI wrapper.
If you are using docx, you could try docx4j.
See the AddImage sample
Surely:
Take a look at this: http://code.google.com/p/java2word
Word 2004+ is XML based. The above framework gets the image, convert to Base64 representation and adds it to the XML.
When you open your Word Document, there will be your image.
Simple like this:
IDocument myDoc = new Document2004();
myDoc.getBody().addEle("path/myImage.png"));
Java2Word is one API to generate Word Docs using obviously Java code. J2W takes care of all implementation and XML generation behind the scenes.
As far as can be gathered from the project website: no.
POI's HWPF can extract an MS Word document's text and perform simple modifications (basically deleting and inserting text).
AFAIK it can't do much more than that.
Also keep in mind that HWPF works only with the older MS Word (97) format, not the latest ones.
Not sure if Java out of the box can do it directly. But i've read about a component that can pretty much do anything in terms of automating word document generation without having Word. Aspose Words
JasperReports uses this API alternatively to POI, because it supports images:
JExcelAPI
I didn't try it yet and don't know how good/bad it is.

I have been given a Microsoft Word Document, with some tables and spots to fill in automatically. I am not sure if this can be done with JAVA, which is my most preferable language.
I am looking for a way to implement a function which I can give the word file to it, and it fills the required spots for me. Is it possible to do it? A hint or a link to a tutorial would definitely suffice. Thanks.
Newer versions Word store documents as zipped XML. Have you filled out the form manually in Word and done a before/after comparison on the XML? Depending on the extent of the changes you could use the standard Java XML APIs to do the same thing programmatically.
A bit of googling and I found docx4j and Apache POI. I haven't used either personally, but it appears that what you're asking for is certainly possible. See this example from the POI SVN repo on how to manipulate tables.
I need to create a little desktop app in Java that creates for me a .doc file and writes a bit of text into the file. I found an interesting tool called Aspose, but i saw it is not free at all.
Do yoy know what kind of, java API can i use for doing that(for free)?
Is it possible to do that only with the java SE libraries?
What do you think would be the easiest and fastest way to achive this goal?
I suggest you have a look at the Apache POI framework, specifically the HWPF - Java API to Handle Microsoft Word Files:
HWPF is the name of our port of the Microsoft Word 97(-2007) file format to pure Java. It also provides limited read only support for the older Word 6 and Word 95 file formats.
if you are going with .doc then as a learning excercise, open a Word document with some content (ideally similar to what you want to create) then save that as XML, and review the contents.
you will need to do some basic DOM parsing and management in your code to insert the right stuff.
By .doc file, I assume you mean Microsoft Office? Reading and writing Office file formats is something of a black art. Does it have to be a .doc format file specifically? A lot easier would be to write out a Rich Text Format file (.rtf) that Word could load.
And if you don't need to use .doc specifically I would suggest you use .odt, http://www.jopendocument.org/.
By "not depend on automation", I mean that it should not require a Microsoft Office installation to work; let alone interact with a live instance of a Microsoft Office component. One such library is Aspose.Total for Java. Are there any more out there?
Another solution I'm considering is to use OpenOffice.org. However, I'm not sure if I'm going to run into the same problems as with Microsoft Office as detailed here.

I have not tried this myself, but Apache usually deliver good libraries
For just Excel: JExcel API for Java
I use this for one application, and it works quite well. May use a fair bit of RAM for larger documents.
One designed specifically to with with the newer XML formats is docx4j: http://dev.plutext.org/trac/docx4j
There are two further answers for this question. Depending on your application.
can borrow from the OpenOffice library code that deals with opening and saving MS Office files. (See: http://www.artofsolving.com/opensource/jodconverter or jOpenDocument )
You might just use OpenOffice itself by scripting or automating that.
I faced this question a while back with a Ruby app and because I was in control of the source document, I got the originator to save things as HTML format and used Tidy to filter the junk. Another option it to find a tool to convert the Office files to RTF which is more generic.
Another to consider ...
LibreOffice looks useful.
jExcelAPI if you just want excel.
Finally there are some opportunities on sourceForge, try this search: http://sourceforge.net/search/?q=java+ms+office
You may find spreadsheets BIG unless you use OpenOffice or MS Office because you need to have a fancy shamancy virtual sparse matrix to do what they do well.
ODF Toolkit - http://odftoolkit.org
I am very new to java. I am trying to fetch some data from a database and the result set is displayed in excel. I am able to inetract with database. But how should I go ahead for inserting data into excel sheet.Its simple Java program and in future I would like to generate files in other format say PDF, doc etc.
I am looking for an approach with lesser load on CPU, faster.
thanks in advance for help.
Just spit out a CSV file. It's lightweight and portable. You can grab a csv writer from Apache commons I think but spending the 10 min it would take to write one might be a good learning exercise as well.
If you want a real solution where you want different outputs (eg excel, pdf, rich text etc) then use a reporting tool. There are plenty of opensource tools like ireport which will let you create a template then write a simple java app that renders that to pdf, excel etc. Otherwise you will end up doing it by hand. It's a bit heavyweight but anything more than trival tabular output will be easier.
Apache POI is for you in this case, but you will find it a little bit overwhelmed if you just need to write/read data from an excel file.
Try jExcel instead, the API is simple and straightforward, you can also manipulate sheets within an excel workbook.
The easiest and standard way of doing this is to use POI library:
http://poi.apache.org/spreadsheet/quick-guide.html
The new xlsx format is based on Open-XML and would provide a method of generating these files without any dependency on Microsoft-office COM libraries -- the same could done for docx and pptx formats later, as well as other open-Xml formats like EPUB.
The Apache POI project looks like it might provide one possible solution. There's also an article on the MSDN interop blog that discusses this in some detail.
The key words you should google for are OLE and DDE.
Though, Java is not the best language for interface Microsoft's software.
for generating excel i think you should try simreport in jsimreport.com. in my opinion, it's quite simple to make an excel report, it uses the excel sheet to generate report so easy to config and visually
How to extract some images from PowerPoint and Word documents, in order to manipulate them, and after that, put the images back in the MS Office files?
Apache has a project called "POI" explicitly made for interacting with MS Office formats from Java. Hopefully that does it for you!
http://poi.apache.org/
Apache POI can handle Word documents via its HWPF module, and extract or insert images from these. Although it's not well documented, check out the POI unit tests for image manipulation within Word (the unit tests seem to be the best documentation for this module).
Failing that, the COM interface is accessible via (say) JACOB. That's probably more work, but will make available APIs not exposed via POI.
In terms of C++, Word exposes a COM API to allow you to manipulate its document format, so as long as you have Word installed on the machine, you can do this in C++ quite easily. Word isn't open source, but you probably have the license anyway.
The company I work for, SoftArtisans, has a product called OfficeWriter that allows you do that, among other things, for Word and Excel (PowerPoint is planned to be added in the future). It is not free or open sourced though.
On the other hand, if you are working strictly with 2007 format (XML based) you can probably use OpenXML.
