  • JAVA Excel POI API: Problem

    - by Bilal
    Hi All, I am using the Java POI package to access the excel files. I have an excel file for which i am updating the cell values. those values are being used in some other sheets (within the same excel file) however, when i open the file, those values don't updated. when i select the cell text and hit enter then all the remaining sheets get the value. please suggest if I am missing something... Thanks ABH

  • to get columns from Excel files using Apache POI??

    - by posdef
    Hi, In order to do some statistical analysis I need to extract values in a column of an Excel sheet. I have been using the Apache POI package to read from Excel files, and it works fine when one needs to iterate over rows. However I couldn't find anything about getting columns neither in the API (link text) nor through google searching. As I need to get max and min values of different columns and generate random numbers using these values, so without picking up individual columns, the only other option is to iterate over rows and columns to get the values and compare one by one, which doesn't sound all that time-efficient. Any ideas on how to tackle this problem? Thanks,

  • Configuring Seam for Glassfish

    - by Walter White
    Hi all, I am still migrating to Glassfish instead of Jetty for our application servers and am running into some problems. The application starts up fine, the database tables are created by hibernate and data is imported by my database importer, so Seam is alive, running and well. It appears that Seam is not properly bound to any JSF lifecycle as I'm getting no active application scope: INFO: Initializing filter:

  • Upgrading Apache to 2.2.23 on ubuntu 12.04 LTS

    - by Salil P
    We had done a PCI scan on one of our servers running Ubuntu 12.04 LTS with apache 2.2.22. The scan reported a vulnerability in apache 2.2.22 (Apache HTTP Server Zero-Length Directory Name in LD_LIBRARY_PATH Vulnerability).The report states to upgrade the version to the latest stable release of either 2.2.23 or 2.2.24. How do I upgrade to the 2.2.23 to fix the vulnerability or is there a patch available that can fix this and if yes can you let me know how that can be patched.

  • Apache virtual host does not work properly

    - by Jori
    I have read a lot of information all over the Internet regarding this subject, and can not figure out what I'am doing wrong. I'm trying to host two websites under different names locally under Windows 7 with Apaches Virtual Hosting functionality. This is what I have done already: In the httpd.conf file I uncommented the following line, so that the virtual host configuration file will be included in the main configuration sequence. # Virtual hosts Include conf/extra/httpd-vhosts.conf This is how I edited my httpd-vhosts.conf: # # Virtual Hosts # # If you want to maintain multiple domains/hostnames on your # machine you can setup VirtualHost containers for them. Most configurations # use only name-based virtual hosts so the server doesn't need to worry about # IP addresses. This is indicated by the asterisks in the directives below. # # Please see the documentation at # <URL:http://httpd.apache.org/docs/2.2/vhosts/> # for further details before you try to setup virtual hosts. # # You may use the command line option '-S' to verify your virtual host # configuration. # # Use name-based virtual hosting. # NameVirtualHost *:80 # # VirtualHost example: # Almost any Apache directive may go into a VirtualHost container. # The first VirtualHost section is used for all requests that do not # match a ServerName or ServerAlias in any <VirtualHost> block. # #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot "C:/apache/docs/dummy-host.localhost" # ServerName dummy-host.localhost # ServerAlias www.dummy-host.localhost # ErrorLog "logs/dummy-host.localhost-error.log" # CustomLog "logs/dummy-host.localhost-access.log" common #</VirtualHost> # #<VirtualHost *:80> # ServerAdmin [email protected] # DocumentRoot "C:/apache/docs/dummy-host2.localhost" # ServerName dummy-host2.localhost # ErrorLog "logs/dummy-host2.localhost-error.log" # CustomLog "logs/dummy-host2.localhost-access.log" common #</VirtualHost> <VirtualHost *:80> ServerName arterieur DocumentRoot "J:/webcontent/www20" <Directory "J:/webcontent/www20"> Order allow,deny Allow from all </Directory> </VirtualHost> As you can see I commented the Virtual Host examples out and added my own one (I did one for this example). Also am I sure that J:\webcontent\www20 exists. At last I edited the Windows host file located in: C:\Windows\System32\drivers\etc\hosts, now it looks this: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 arterieur Then I restarted Apache with the Apache Service Monitor, and it gave me the following fatal error: The requested operation has failed!, I tried to look at the apache/logs/error.log file but I did not log anything, I guess it only logs the errors after startup. Does anyone knows what I'am doing wrong?

  • Differences between "apache"'s installations

    - by JustTrying
    Are there any differences between installing Apache httpd using sudo apt-get install apache2 (as the guide of Ubuntu says - https://help.ubuntu.com/12.04/serverguide/httpd.html ) or following the steps on the Apache documentation (http://httpd.apache.org/docs/2.4/install.html#overview)? I tried both ways; in the first case (using apt-get) the server seems to work - I open a browser page and I got it. In the second case I need other packages (apr, apr-util and pcre) and so I abandoned the attempt.

  • Problem to install Apache 2.4.2 in Ubuntu 12.04

    - by Michael
    I followed these steps to install Apache 2.4.2 in Ubuntu 12.04, but it seems Apache is not installed, here's what I did (I followed the steps in this site http://www.discusswire.com/apache-2-4-installation-ubuntu/): sudo apt-get install build-essential sudo apt-get build-dep apache2 wget http://apache.mirrors.pair.com/httpd/httpd-2.4.2.tar.gz tar -xzvf httpd-2.4.2.tar.gz && cd httpd-2.4.2 sudo ./configure --prefix=/usr/local/apache2 --enable-mods-shared=all --enable-deflate --enable-proxy --enable-proxy-balancer --enable-proxy-http --with-mpm=prefork sudo make sudo make install when I tried to start by issuing sudo /usr/local/apache2/bin/apachectl start at terminal, I got the following warning: "AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message" and when I typed top at terminal, the apache is not there. I also tried to go to http://localhost/ or 127.0.0.1 or even 127.0.1.1 it showed "Can't establish connection to server ..." message. ps: I checked the error log and it showed "[Fri Jul 27 15:49:00.703901 2012] [proxy_balancer:emerg] [pid 20781] AH01177: Failed to lookup provider 'shm' for 'slotmem': is mod_slotmem_shm loaded??

  • Oracle Response to Apache Departure from JCP

    - by Henrik Ståhl
    Last month Oracle renominated Apache to the Java Executive Committee because we valued their active participation and perspective on Java. Earlier this week, by an overwhelming majority, the Java Executive Committee voted to move Java forward by formally initiating work on both Java SE 7 and SE 8 based on their technical merits. Apache voted against initiating technical committee work on both SE 7 and SE 8, effectively voting against moving Java forward. Now, despite supporting the technical direction, Apache have announced that they are quitting the Executive Committee. Oracle has a responsibility to move Java forward and to maintain the uniformity of the Java standard for the millions of Java developers and the majority of Executive Committee members agree. We encourage Apache to reconsider its position and remain a part of the process to move Java forward. ASF and many open source projects within it are an important part of the overall Java ecosystem. Adam Messinger, Vice President of Development

  • subdomain/virtualhost problem on unix + apache

    - by Aaron
    Hello, I'm having a strangely difficult time setting up a subdomain (x.example.com). The main site works fine, but I get 404 errors attempting to hit x.example.com no matter how I set up the VirtualHost config. NameVirtualHost *:80 <VirtualHost *:80> ServerName www.example.com DocumentRoot /var/www/example.com/htdocs ServerAlias example.com </VirtualHost> <VirtualHost *:80> ServerName x.example.com ErrorLog /var/logs/x-error-log CustomLog /var/logs/x-access-log common DocumentRoot /var/www/x/htdocs </VirtualHost> As far as I can tell, this is a vanilla set up. Any suggestions would be appreciated.

  • Java POI 3.6 XWPF usage guidelines (reading content of docx file)

    - by Mr CooL
    I assume the following objects should be used to read contents of DOCX file: XWPFDocument XWPFWordExtractor However, somewhere the compiler warns me from not including the correct libraries needed in classpath. I think I'm kinda lost for not knowing which jar file is the right one to include for this since there are so many jar files (POI libraries). My project so far involve in reading doc and docx files as part of the project. I've managed to read the contents of doc file. However, for docx file, I'm still having problem with that. Can anyone show the guidelines in terms of the codes and libraries needed (jar files) to read the content of docx file? I'm trying to limit the libraries need to be added on into project since I need to read doc and docx only. The following works for doc: fs = new POIFSFileSystem(new FileInputStream(fileName)); HWPFDocument doc = new HWPFDocument(fs); WordExtractor we = new WordExtractor(doc); String[] p = we.getParagraphText();

  • How to stop an IOException error using whilst using a combination of jython, pyro and ant?

    - by Kelso
    So the wonderful low down on this doozie of a problem: short version: We are building a distribution system for this item of software we're using. Basically we take out build artifact, store it on an ftp server which passes it to multiple clients which execute scripts to patch their servers. Long version: 1 distribution server multiple client servers software: jython 2.5.1, ant 1.8.0, pyro 3.10 The distribution server has an FTP server and a PYRO client running on it. Each client server has a PRYO server running on it. When the PYRO client is told to start the patch procedure then it reads a machine list which contains a list of all the client servers. Then connects to each of the PYRO servers one by one and execute the patch procedure. The procedure is: getPatch (gets the latest patch for that server), StopServer (stops the software that may or maynot be accessing what needs to be patched), Apply patch, StartServer. Each of the processes calls an ANT script that passes with some folder names and other config passes around. The fun part happens when you go to apply the patch. See below for error log. I had to remove the folder names because of NDA reasons. This is where it gets interesting. Running each section of the procedure individually. i.e. running getPatch, StopServer, etc. one at a time manually. This bug doesn't happen. Physically goign to the machine and running the processes it doesn't happen. Only when we call all 4 of the processes one after the other. It occurs during the ApplyPatch phase when an ANT replace script is called on multiple files. We think it might have something to do with the JVM keeping hold of the file for a split second or 2. however this is meant to have been patched according to the bug notes on ant. so in short: distribution server == jython == pyro connection == client server == jython == ant script Error Log: <*snip>\ant\deploy.xml:12: IOException in <*snip>\bin\startGs.sh - java.io.IOException:Failed to

  • HTTP requests and Apache modules: Creative attack vectors

    - by pinkgothic
    Slightly unorthodox question here: I'm currently trying to break an Apache with a handful of custom modules. What spawned the testing is that Apache internally forwards requests that it considers too large (e.g. 1 MB trash) to modules hooked in appropriately, forcing them to deal with the garbage data - and lack of handling in the custom modules caused Apache in its entirety to go up in flames. Ouch, ouch, ouch. That particular issue was fortunately fixed, but the question's arisen whether or not there may be other similar vulnerabilities. Right now I have a tool at my disposal that lets me send a raw HTTP request to the server (or rather, raw data through an established TCP connection that could be interpreted as an HTTP request if it followed the form of one, e.g. "GET ...") and I'm trying to come up with other ideas. (TCP-level attacks like Slowloris and Nkiller2 are not my focus at the moment.) Does anyone have a few nice ideas how to confuse the server and/or its modules to the point of self-immolation? Broken UTF-8? (Though I doubt Apache cares about encoding - I imagine it just juggles raw bytes.) Stuff that is only barely too long, followed by a 0-byte, followed by junk? et cetera I don't consider myself a very good tester (I'm doing this by necessity and lack of manpower; I unfortunately don't even have a more than basic grasp of Apache internals that would help me along), which is why I'm hoping for an insightful response or two or three. Maybe some of you have done some similar testing for your own projects? (If stackoverflow is not the right place for this question, I apologise. Not sure where else to put it.)

  • is it really necessary to run Apache as a front-end to Glassfish/JBoss/Tomcat?

    - by Caffeine Coma
    I'm primarily a Java developer, and I come to you with a question that straddles the divide between developers and sysadmins. Years ago, when it was a novel thing to run Tomcat as an app server, it was customary to front it with Apache. As I understand it, this was done because: Java was considered "slow", and it was helpful to have Apache serve static content directly. Tomcat couldn't listen to ports 80/443 unless run as root, which was dangerous. Java is no longer considered slow, and I doubt adding Apache to the mix will actually help speed things up. As for the ports issue, there are probably simpler ways to connect app servers to ports 80/443 these days. So my question is- is there really any benefit to fronting Java Webapps with Apache these days? If so, is Apache still the way to go? Should I look at Nginx? Instead of Tomcat I'm using Glassfish, if that matters.

  • Excel workbooks produced by POI don't work when linked

    - by Eric Nicolas
    Here is what I'm doing : Create a workbook in memory (book = new HSSFWorkbook(), ...) Save it to disk (book.write(...)) Open in Excel (ok) Create another workbook in Excel, which links to the first one (=PoiWorkbook?xls!A1) Close Excel Then everytime I open the second workbook again, all the links are #N/A, unless I also open the POI-generated workbook at the same time. I never saw this behaviour with standard workbooks created in Excel. Anyone has seen this and found a workaround ? Thanks.

  • Locating memory leak in Apache httpd process, PHP/Doctrine-based application

    - by Sam
    I have a PHP application using these components: Apache 2.2.3-31 on Centos 5.4 PHP 5.2.10 Xdebug 2.0.5 with Remote Debugging enabled APC 3.0.19 Doctrine ORM for PHP 1.2.1 using Query Caching and Results Caching via APC MySQL 5.0.77 using Query Caching I've noticed that when I start up Apache, I eventually end up 10 child processes. As time goes on, each process will grow in memory until each one approaches 10% of available memory, which begins to slow the server to a crawl since together they grow to take up 100% of memory. Here is a snapshot of my top output: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1471 apache 16 0 626m 201m 18m S 0.0 10.2 1:11.02 httpd 1470 apache 16 0 622m 198m 18m S 0.0 10.1 1:14.49 httpd 1469 apache 16 0 619m 197m 18m S 0.0 10.0 1:11.98 httpd 1462 apache 18 0 622m 197m 18m S 0.0 10.0 1:11.27 httpd 1460 apache 15 0 622m 195m 18m S 0.0 10.0 1:12.73 httpd 1459 apache 16 0 618m 191m 18m S 0.0 9.7 1:13.00 httpd 1461 apache 18 0 616m 190m 18m S 0.0 9.7 1:14.09 httpd 1468 apache 18 0 613m 190m 18m S 0.0 9.7 1:12.67 httpd 7919 apache 18 0 116m 75m 15m S 0.0 3.8 0:19.86 httpd 9486 apache 16 0 97.7m 56m 14m S 0.0 2.9 0:13.51 httpd I have no long-running scripts (they all terminate eventually, the longest being maybe 2 minutes long), and I am working under the assumption that once each script terminates, the memory it uses gets deallocated. (Maybe someone can correct me on that). My hunch is that it could be APC, since it stores data between requests, but at the same time, it seems weird that it would store data inside the httpd process. How can I track down which part of my app is causing the memory leak? What tools can I use to see how the memory usage is growing inside the httpd process and what is contributing to it?

  • Apache Process question about RAM usage

    - by Andrew Fashion
    So everytime I load a new page, I notice a new HTTPD process opens, every time I click a page, and each process says it's using anywhere from 2-4.5% of memory. Does that mean every single process is running at that time using 2-4% of RAM? It's a brand new server and I'm the only one on the server at the moment. Or does it mean all the other processes are dying, and only the new one is active. Because 4% of my 2048MB of RAM is already 82MB for just one process!?!? Let me know, because I am trying to determine what I need to beef my server up in order to handle high loads of traffic. I'm expect to get 20,000 uniques per day on launch. I am currently running a Dual Quad Xeon server, with only 2GB of ram, I will upgrade to 8GB or more shortly. Let me know what you suggest! thank you [root@D18634 log]# top | grep 'httpd' 11315 apache 15 0 362m 82m 24m R 12.3 4.1 0:03.00 httpd 11310 apache 16 0 322m 41m 21m S 5.7 2.1 0:02.98 httpd 11315 apache 15 0 362m 83m 25m S 24.3 4.1 0:03.73 httpd 11319 apache 16 0 324m 42m 20m R 1.0 2.1 0:01.85 httpd 11319 apache 16 0 362m 82m 23m R 78.5 4.1 0:04.21 httpd 11321 apache 16 0 323m 44m 23m S 35.3 2.2 0:04.13 httpd 11319 apache 15 0 361m 82m 23m S 8.3 4.1 0:04.46 httpd 11321 apache 15 0 323m 44m 23m S 35.9 2.2 0:05.21 httpd 11313 apache 15 0 324m 41m 19m S 48.6 2.1 0:03.23 httpd 11322 apache 16 0 354m 72m 20m R 11.0 3.6 0:05.11 httpd 11322 apache 16 0 354m 72m 20m S 23.9 3.6 0:05.83 httpd 11314 apache 16 0 355m 75m 22m R 18.3 3.7 0:04.64 httpd

  • Optimizing apache server load

    - by Jevgeni Smirnov
    We have an issue with a dedicated server load. We have 16 processors with 4 core @ 2.40GHz, if I understood correctly cat /proc/cpuinfo output. Unfortunately, I don't have access to free -m or vmstat. But from top I got that we have 24 GB. And snapshot from top about processes: As far as I see, memory is not used at all. But the cpu is used heavily. Apache consumes most of CPU. Another useful piece of information: Every 1.0s: ps u -C httpd,mysqld,php Tue Mar 27 10:48:19 2012 USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND root 7476 0.0 0.1 446808 37880 ?

  • Problem with using APACHE-POI to convert PPT to Image

    Hi all, I got a problem when I try to use Apache POI project to convert my PPT to Images.My code as follows: FileInputStream is = new FileInputStream("test.ppt"); SlideShow ppt = new SlideShow(is); is.close(); Dimension pgsize = ppt.getPageSize(); Slide[] slide = ppt.getSlides(); for (int i = 0; i < slide.length; i++) { BufferedImage img = new BufferedImage(pgsize.width, pgsize.height, BufferedImage.TYPE_INT_RGB); Graphics2D graphics = img.createGraphics(); //clear the drawing area graphics.setPaint(Color.white); graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, pgsize.height)); //render slide[i].draw(graphics); //save the output FileOutputStream out = new FileOutputStream("slide-" + (i+1) + ".png"); javax.imageio.ImageIO.write(img, "png", out); out.close(); It works fine except that all Chinese words are converted to some squares.The png image I got is like following image: Then how can I fix this?Thanks in advance!

  • Issue reading in a cell from Excel with Apache POI

    - by Nick
    I am trying to use Apache POI to read in old (pre-2007 and XLS) Excel files. My program goes to the end of the rows and iterates back up until it finds something that's not either null or empty. Then it iterates back up a few times and grabs those cells. This program works just fine reading in XLSX and XLS files made in Office 2010. I get the following error message: Exception in thread "main" java.lang.NumberFormatException: empty String at sun.misc.FloatingDecimal.readJavaFormatString(Unknown Source) at java.lang.Double.parseDouble(Unknown Source) at the line: num = Double.parseDouble(str); from the code: str = cell.toString(); if (str != "" || str != null) { System.out.println("Cell is a string"); num = Double.parseDouble(str); } else { System.out.println("Cell is numeric."); num = cell.getNumericCellValue(); } where the cell is the last cell in the document that's not empty or null. When I try to print the first cell that's not empty or null, it prints nothing, so I think I'm not accessing it correctly.

  • Apache VERY high page load time

    - by Aaron Waller
    My Drupal 6 site has been running smoothly for years but recently has experienced intermittent periods of extreme slowness (10-60 sec page loads). Several hours of slowness followed by hours of normal (4-6 sec) page loads. The page always loads with no error, just sometimes takes forever. My setup: Windows Server 2003 Apache/2.2.15 (Win32) Jrun/4.0 PHP 5 MySql 5.1 Drupal 6 Cold fusion 9 Vmware virtual environment DMZ behind a corporate firewall Traffic: 1-3 hits/sec avg Troubleshooting No applicable errors in apache error log No errors in drupal event log Drupal devel module shows 242 queries in 366.23 milliseconds,page execution time 2069.62 ms. (So it looks like queries and php scripts are not the problem) NO unusually high CPU, memory, or disk IO Cold fusion apps, and other static pages outside of drupal also load slow webpagetest.org test shows very high time-to-first-byte The problem seems to be with Apache responding to requests, but previously I've only seen this behavior under 100% cpu load. Judging solely by resource monitoring, it looks as though very little is going on. Here is the kicker - roughly half of the site's access comes from our LAN, but if I disable the firewall rule and block access from outside of our network, internal (LAN) access (1000+ devices) is speedy. But as soon as outside access is restored the site is crippled. Apache config? Crawlers/bots? Attackers? I'm at the end of my rope, where should I be looking to determine where the problem lies?

  • Apache Not Accepting a Path in My Home Folder

    - by Promather
    I have trying to set up an Apache site to use a folder in my home folder without any success. I exactly followed the steps in this page: https://help.ubuntu.com/community/ApacheMySQLPHP yet I did not succeed; I keep getting error 403, which says that the server doesn't have permission to access the requested page. I searched forums and many suggested changing the permission of the folder. I went straight away and set the permission to 777, but that didn't solve the problem. I made another search and somebody gave me a clue, which is that it could be because my home folder is encrypted. I believe this could be the problem, but: What is the relation between encryption and Apache? I suppose Apache server is requesting the file from the system, rather than trying to access the file bytes! Is there anyway to solve this problem? I don't want to move the folder to /var/www because I am using this Apache for testing, so I want whatever change I make to be immediately reflected, rather than having to copy files which is error prone.
