Off Topic? Apache POI

I am experimenting with Apache and have
tried the following with success:
I hope you don't mind my posting here
with an Apache question, the Apache site
seems to be unavailable at the moment, but
then again, it is still Java.
Thanks.
    HSSFWorkbook wb = new HSSFWorkbook();
    FileOutputStream fileOut = new FileOutputStream("C:\\workbook.xls");
    wb.write(fileOut);
    fileOut.close();But the following without success (narrowed down to this line I think).
    XSSFWorkbook wb = new XSSFWorkbook();...this error message.
java.lang.NoClassDefFoundError: org/apache/xmlbeans/XmlException
...tried these imports.
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.xssf.usermodel.*;I don't think it's the path because, as stated above, they both
derive from ss.usermodel.
Anyone have a suggestion?
Thanks,
Jeff.

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.

Help needed to loadjava apache poi jars into oracle database.

Help needed to loadjava apache poi jars into oracle database. Many classes left unresolved. (Poi 3.7, database 11.1.0.7). Please share your experience!

Hi,

It seems to me that the root of the problem is the error:

This class exists in the SYS schema though and is valid. If SYS should be included as a resolver? How to solve this problem?

Apache POI small example request & if it's possible to do...

I'm fairly new to Java, and am interested in creating a dynamic program in swing:
I have a word 2007 document with a number of lines of text and commands from a user manual I have created. I would like to use the Apache POI package to open the document read in each line one by one, and based on what style the line is in (Heading 1 format vs Normal vs Command vs Directory...etc) the program would go through a specific subroutine. For instance if were to have a document down below:
h1. Copy Files Procedure: (heading 1 style)
h2. 1.) Log into the Kermit unix server and change directory to:(heading 2 style)
h4. a.) "$HOME/whatever/" (openSSHwindow style)
h2. 2.) Perform a secure copy to Muppet server. (heading 2 style)
h4. a.) "scp user@server files whatever the command is" (command style)
I would want the program to read in this word doc line by line and spit out in my log file:
"Copy Files Procedure:" is in heading 1 style.
"Log into the Kermit unix server and change directory to:" is in heading 2 style.
"$HOME/whatever/" is in openSSHwindow style.
"Perform a secure copy to Muppet server." is in heading 2 style.
"scp user@server files whatever the command is" is in command style.
...etc
I did some research into Apache POI, but i wanted to know if anyone else here knew a way to do this. All I can find is that there is way to pull out the heading indent level! The problem with is that I'm using custom formats, not just Headings 1-9!
if someone would write a tiny example in java swing showing how to read the line in from a word doc and pull the line content as well as it's line style with a swing method that it invokes if it is a certain that would be SUPER helpful!!!!
The usefulness of this example could allow anyone to use this program to dynamically create an operating console GUI with any properly formatted word doc version of the operators manual!

All I mean with that is one that will create itself based on a word doc and it's styling...So, your program will read a word doc, and then generate Java source code, compile it, and execute it?
I think you're abusing the word "dynamic." It sounds like you mean "a program that takes input and produces output based on that input." This is pretty much what all programs beyond "Hello World" do.

How to Edit Word Document in Oracle ADF Application - Apache POI

Hi All
I was wondering if there is a way to edit and save word documents in Oracle ADF without loosing the Formatting.
I was able to edit and save the word document however the Formatting was lost.
Please let me know if there are any pointers or open source Java APIs that we can use to achieve this.

Refer the Text Formatting section
Apache POI - HWPF - Java API to Handle Microsoft Word Files
HWPF Reads in a Word document with minimum formatting (no lists, tables, footnotes, endnotes, headers, footers)
Apache POI - HWPF - Java API to Handle Microsoft Word Files
The _cbt field in class HWPFDocumentCore contains formatting information.
HWPFDocumentCore (POI API Documentation)
For more advanced text extraction needs, including Rich Text extraction (such as formatting and styling), along with XML and HTML output, Apache POI works closely with Apache Tika to deliver POI-powered Tika Parsers for all the project supported file formats.

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

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

Forum Atom feed and the Off-Topic forum

I'm subscribed via https://bbs.archlinux.org/extern.php?ac … der=posted and I've just noticed I don't get any notification if a new thread gets opened in Off-Topic forum. I haven't yet checked if any other forum is also excluded.
I know that I can subscribe to this forum via 'Subscribe to this forum' but according to http://projects.archlinux.org/vhosts/bb … extern.php the default feed shouldn't miss any subforums, as there are no nfids mentioned.

As I recall off-topic, dustbin, and TGN are log-in so that moderation there can be slightly more lenient, since its guaranteed its only our community in the place (no lurkers)? Not part of the 'main' forums in that sense, then.
EDIT: lurkers and/or bots, which is the main point.
This is correct. We don't want someone to type "Arch Linux" in a search engine and to get, as the first link, an off-topic forum thread about some random absurdities or some TGN rant. The same goes with someone visiting the forum to see what kind of community Arch Linux has before installing it. It's a question of giving a good first impression while still being able to have a good time.

Somewhat off topic, wedding lighting and wireless lav. question

Hello everyone! This question is slightly off topic, but I'm desperate for an answer. I've been doing wedding videos for some time now and it's time to upgrade my setup. I'm currently in the market for a good, reliable wireless lavaliere mic, and a good quality on camera light. I use a panasonic DVX100b for all of my footage. For the light I'd like to spend about $400.00 ish or less, but I will spend more if the price jump dramatically increases the performance. I also have about $600 to spend on a wireless lav. system, again I will pay more if the jump in price brings a considerable jump in quality. Can anyone make any recommendations?
Thanks

Gotta go with the Sennheiser Evolution series as well. Although I can't say that the actual mics they ships with are the best, they're not bad and I've had very few issues with the range and reception.
And if you're shooting solo, aside from the mics, make sure you pick up a 2 or 3 foot XLR cable so that you have enough hose to allow you to hook the receiver on to your belt. Beats clipping it to the handle strap.
You can also get a little adapter for the DVX that will allow you to mount the mics on the camera hot shoe on the top of the handle. I'm sure you can get these for just about and wireless you buy.

Suggestion: General Discussions\Off Topic Section

hi,
it would be great to have an off topic forum/section here for us to interact and have general discussions. almost every forum i'm a member of has an Off Topic section. we can get to know each other much better and share useful information and opinions about various topics, technology and others also. we can do the same through PM's, but getting everyone involved will feel much better.

Newbie wireless question (slightly off-topic)

I didn't want to post this here as it's not entirely an Airport-specific question. I posted this to the iBook forums, but nobody there has answered so my apologies if this is not welcome here. (Any moderators can remove it if that's the case.)
I've been using computers extensively for over a decade, but I'm a total newbie to wifi. I just set up a wireless network in my house and would appreciate some advice/feedback.
My main concerns are whether or not my network is reasonably secure. I know there is no such thing as perfect security, but I don't know if what I've done is good enough or not.
I don't have an Airport base station, but I do have a D-Link Airplus G and an Airport card in my iBook. I have WEP set up on the router and I have enabled MAC filtering, listing only my desktop and my iBook, excluding all others from the network.
I'm fairly certain that nobody in my neighborhood is going to get into my machines this way or be able to sniff my network data stream, but am I right in assuming that nobody can "piggyback" on my Internet connection too? Presumably, if everyone but my own machines are MAC-filtered and kept out, then the Internet connection is also protected. Is that how it works?

WEP and MAC filtering are better than nothing, but you can do better. These are my suggestions:
1. Use WPA with a pre-shared key (PSK) and TKIP encryption on your Netgear router, along with an alphanumeric passphrase of at least eight characters not found in any dictionary. The equivalent setting on your Mac is "WPA Personal". Unlike WEP security (which an expert can crack in under half an hour), WPA security is currently unhackable by any practical means as long as you use a non-dictionary passphrase. One last point - WPA security requires all your wireless Macs to be running MacOS 10.3 or newer.
2. MAC filtering is (these days) essentially useless as a wireless security method. Using "packet sniffing" of traffic on your wireless network to find out what MAC addresses are used by computers on your network, and a PC that allows its MAC address to be cloned so that it is identical to the MAC address of one your own wireless computers (which is possible with most PC wireless network adapters) even an amateur hacker can defeat MAC address filtering in minutes.
By the way - I don't think your posted message here is off topic. In my opinion, the Airport discussion forums are the best place to post any questions related to usage of wireless networks. Questions of this nature are virtually never specific to any Mac model.

Slightly off topic - ATI test demos

Hi,
Slightly off topic question but...
Many years ago a friend of mine (albeit a PC user) showed me a graphics card render demo which was a take on the Lobby Scene from The Matrix, designed to show of his (then) high powered graphics card (this was about 8 years ago)
I was wondering if anyone knew of any websites that had these ATI graphics card rendering demos that would show off the power of the ATI X1900 card - I don't mean the .mov and .avi pre-rendered demo videos that are on ATi's site - I've already checked and the only ones they have are the ones for the older x800, what I'm after are things that are more like applications you run that render the video live. (ATI/AMD do have some but they are very old - when SmartShader 2.0 was released)
Anyone know? or alternatively, any other rendering apps that can show of my 512mb's of graphics card-age?
This is purely for entertainment...
Many thanks!
Regards,
Ben
I hope this makes sense!

Usually push connectors for bare wires are designed for less or up to 200 circles ....
Depending on the number of test performed, mounting time, ... I would ask the push button manufacturers for test fixture connectors . Take the linecard of some distributors (digikey, RS ... ) to find them.
Might not be the cheapest solution on the first run, but for daily use good connectors are always worth the money.

Slightly off topic: JDev + 10g + recommended laptop

Hi gang
This is a slightly off-topic post in the forum. Apologies to the forum moderators up front.
I'm in the process of purchasing a new laptop for development. Among other things I need to run Oracle 10g, + JDev + Solitaire.
My assumption for such a laptop is I'll need a fast hd (7200rpm+) for builds, and lots of memory to run Oracle 10g and memory hogging Java JDev. Also extra screen real-estate would be ideal with the multi-pane JDev.
However without the ability to walk into a laptop supplier, load up the software and do some tests, I'm not sure what would be sufficient. I don't want to go overboard on features in order to save $s, but I don't want something that wont run fast enough without bugging the Hell out of me either.
Does anybody have any recommendations on what laptop they are currently running or what they would buy to run Oracle 10g + JDev? Are my assumptions correct or does anybody run this config with less, happily?
Any help appreciated.
Cheers,
CM.

I have been doing all of my jdev + oracle development exclusively on my PowerBook G4 for over a year now. JDev 9.0.5.2 runs great, and so does the new 10.1.3 preview. I have upgraded the memory on it to 1.5 GB, but even with the stock 512 it ran well. Plus, there are all of the productivity benefits from running Mac OS X. I was skeptical about it at first, as you might be, but once I switched over, I haven't even looked back. The 17 inch screen is beautiful, it works just fine on the Windows network at work, has all of the Unix tools underneath, and for the very few times a windows machine is needed, Virtual PC helps out. Do yourself a favor and check it out.

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.
