• hosting a webserver locally with apache on windows

  - by user3697598

  I have been searching for a while now and I have not found what i am looking for! I have installed apache on my local server and I have set up port forwarding, but I don't know how to connect my localhost to the internet were everyone can view it. I do have a domain already too. I just need to know how to point it to my local server. If you could tell me or point me in the right direction on what I need to do. It would be much appreciated.

• How to continue copying on error with copyDirectory from FileUtils (Apache Commons IO 2.4)

  - by Exocom

  I am trying to copy files from one folder to another using the FileUtils method "static void copyDirectory(File srcDir, File destDir)" from apache commons io (2.4) with the following code: String srcDir = "/sourceDirectory/examples/"; String destDir = "/tmp/examples/"; try{ FileUtils.copyDirectory(new File(srcDir), new File(destDir)); } catch (IOException e){ e.printStackTrace(); } The file structure looks like the following: examples/ (read access) examples/.subdirectory (NO access) examples/file1.txt (read access) examples/file2.txt (read access) examples/subdirectory2/file1.txt (read access) examples/subdirectory2/file2.txt (NO access) The problem is, that in srcDir there are a few files and one subdirectory I don't have access to. FileUtils.copyDirectory throws an "java.io.FileNotFoundException: .subdirectory (Permission denied)" and aborts. Is it possible to ignore those files I don't have permission to and just copy all the other files I can read?

• linux+apache+sqlite=death?

  - by acidzombie24

  The title is a joke. However it is serious as far as my app is concerned. I am running apache with mod mono and my asp.net app is using mono sqlite as its db. When i refresh the page twice i get the DB is locked error. The folder it is in is chmod 777. The webapp is creating sqlite.db and sqlite.db-journal but it doesnt seem to be able to delete the journal. i'm confused. What permissions do i need to set these? i tried precreating the files using 777 and had no luck.

• Apache - Restrict to IP not working.

  - by Probocop

  Hi, I've a subdomain that I only want to be accessible internally; I'm trying to achieve this in Apache by editing the VirtualHost block for that domain. Can anybody see where I'm going wrong? Note, my internal IP address here are 192.168.10.xxx. My code is as follows: <VirtualHost *:80> ServerName test.epiphanydev2.co.uk DocumentRoot /var/www/test ErrorLog /var/log/apache2/error_test_co_uk.log LogLevel warn CustomLog /var/log/apache2/access_test_co_uk.log combined <Directory /var/www/test> Order allow,deny Allow from 192.168.10.0/24 Allow from 127 </Directory> </VirtualHost> Thanks

• Find hosted directories Jetty/Apache

  - by Paul Creasey

  Hi, Let say I have a directory which is being hosted by Jetty or Apache (i'd like an answer for both), i know the URL including the port and i can log into the server. How can i find the directory that is being hosted by a certain port? I'd also like to go the other way, i have a folder on the server, which i know if being hosted, but i don't know the port so i can't find it in a web browser. How can i find a list of directories that are being hosted? This has been bugging me for ages but i've never bothered to ask before! Thanks.

• Phishing attack stuck with jsp loginAction.do page? [closed]

  - by user970533

  I 'm testing a phishing website on a staged replica of an jsp web-application. I'm doing the usual attack which involves changing the post and action field of source code to divert to my own written jsp script capture the logins and redirect the victim to the original website. It looks easy but trust me its has been me more then 2 weeks I cannot write the logins to the text file. I have tested the jsp page on my local wamp server it works fine. In staged when I click on the ok button for user/password field I'm taken to loginAction.do script. I checked this using tamper data add on on firefox. The only way I was able to make my script run was to use burp proxy intercept the request and change action parameter to refer my uploaded script. I want to know what does an loginAction.do? I have googled it - its quite common to see it in jsp application. I have checked the code; there is nothing that tells me why the page always point to the .do script instead of mine. Is there some kind of redirection in tomcat configuration. I like to know. I'm unable to exploit this attack vector? I need the community help

• Intermittent extrememly long response times when downloading documents

  - by pap

  I have a Java web application running om Tomcat 7 with an Apache httpd 2.2 fronting with mod_jk/AJP. One part of the application is serving files (up to 4mb size). Now, normally this all runs very smooth with stable, low response-times. However, in rare instances (<0.1% of downloads), the downloadtime will go beyond 1 minute. After activating the ThreadStuckValve in Tomcat, I can see that the long responses seem to be stuck at org.apache.tomcat.jni.Socket.sendbb(Native method) i.e network I/O. At most, these long-running downloads take 5 minutes, which I strongly suspect is because of the default 300 second timout in Apache 2.2 (http://httpd.apache.org/docs/2.2/mod/core.html, "TimeOut directive"). To me, this looks like network problems. The Apache timeout (if that is what is kicking in at the 5 minute mark) indicates that ACK packets are not being transmitted correctly. My questions are what could be causing this? Closed browser at receiving end but socket not signaled as closed properly? Packet loss or some other network failure in transit? Where would I start troubleshooting this? We're running Tomcat and Apache on Windows server 2008-R2 in a vmware virtualized server.

• safely hosting a django project over apache using centos

  - by tipu

  Error can be seen at: http://djaffry.selfip.com:8080/ I had a project working great, but I had all the files under /var/www/ and with my limited understanding it's bad, according to django's site: "If your background is in PHP, you’re probably used to putting code under the Web server’s document root (in a place such as /var/www). With Django, you don’t do that. It’s not a good idea to put any of this Python code within your Web server’s document root, because it risks the possibility that people may be able to view your code over the Web. That’s not good for security. Put your code in some directory outside of the document root, such as /home/mycode." So I went to /home/tipu/stuff/ and executed django-admin.py startproject twingle. Then I went to apache and did <VirtualHost *:8080> ServerName tweet_search_engine DocumentRoot /home/tipu/stuff/twingle/ </VirtualHost> <Directory /home/tipu/stuff/twingle> SetHandler python-program PythonHandler django.core.handlers.modpython SetEnv DJANGO_SETTINGS_MODULE settings PythonOption django.root /home/tipu/stuff/twingle PythonDebug On PythonPath "['/home/tipu/stuff/', '/home/tipu/stuff/twingle/'] + sys.path" </Directory> Now I am getting a 403 Forbidden error.. any idea what I'm doing wrong? I'm newer to Linux (CentOS) and django, so I could be over looking some very simple things.

• Apache POI Comment Excel

  - by Marquinio

  I need to add a comment to an HSSF Cell in Excel. Everything works fine the very first time but if I open the same file and run the code again it corrupts the file. I've also noticed that I need to create a Drawing object on a Sheet only once: _sheet.createDrawingPatriarch(); If the line above gets executed more than once comments will not work. So has anyone tried adding comments to Cells, closing the file, opening the file again and trying to add more comments to different cells? The below code works but if I open the file again then comments are not added, plus the file gets corrupted!!! Is there a way to get the existing Drawing object from a Sheet? Any ideas appreciated. Thanks!! _drawing = (HSSFPatriarch) _sheet.createDrawingPatriarch(); Row row = _sheet.getRow(rowIndex_); Cell cell = row.getCell(0); CreationHelper factory = _workbook.getCreationHelper(); HSSFAnchor anchor = new HSSFClientAnchor(0, 0, 0, 0, (short)4, 2, (short)6, 5); org.apache.poi.ss.usermodel.Comment comment = _drawing.createComment(anchor); RichTextString str = factory.createRichTextString("Hello, World "+rowIndex_); comment.setString(str); cell.setCellComment(comment);

• [Apache Camel] Generating multiple files based on DB query in a nice way

  - by chantingwolf

  Dear all, I have a following question. I have to generate many files based on sql query. Let's say for example, I have get from database a list of orders made today and genarate file for each order and later store each file on ftp. Ideally I would like to get follewing. Not quite sure how to get it. from(MyBean).to(Ftp) The problem and main question is how to generate multiple messages by custom bean (for example). I am not sure if splitter EIP is ok in this case because in my case I have not just one message to split, but I just have to generate and send many messages. http://camel.apache.org/splitter.html I hope, someone meet this problem before. If the task will be to generate just one file - everything is quite simple - you need just fill Exchange.OutMessage (or something like this). But what about multiple files - I really can't get, how to manage this situation. P.S. Sorry if this question is stupid. I am novice in Camel (working with it just for coupe weeks). It's a great tool. Actually, that's why I want to use in in the best way. Thanks a lot.

• svn+apache per directory access control: weird permissions issue (403 Forbidden error)

  - by gveda

  Hi, I had a perfectly working svn+apache install where I was using per directory access control to restrict access to various parts of the repository. In particular, no one had access to the top level in the repository [/]. People had access to folders like [/www] etc. I was specifying these permissions in a file (svn-access-file). I had to move to a new machine. So I installed subversion-1.6.3 and httpd-2.2.11 on it, and modified the conf file to mimic the conf file on the old machine (and I copied the svn-access-file and the svn-auth-file). Then I took an svn dump and did a load to put stuff back in the new repository. Now I can check stuff out, modify stuff, and commit. However, as soon as I try to do an 'svn up' on an already checked out copy of some sub-folder [/www/people], I get the following error: svn: Server sent unexpected return value (403 Forbidden) in response to OPTIONS request for 'https://[servername]/svn' It seems the problem is that it is trying to access the top level directory [/] even though really it should only be trying to access [/www]. If I temporarily give the user access to [/], it works. Can someone please tell me how to fix this? Everything worked on the old machine. Thanks! Gaurav

• 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] Creating rewrite rules for multiple urls in the same folder

  - by DavidYell

  I have been asked by our client to convert a site we created into SEO friendly url format. I've managed to crack a small way into this, but have hit a problem with having the same urls in the same folder. I am trying to rewrite the following urls, /review/index.php?cid=intercasino /review/submit.php?cid=intercasino /review/index.php?cid=intercasino&page=2#reviews I would like to get them to, /review/intercasino /submit-review/intercasino /review/intercasino/2#reviews I've almost got it working using the following rule, RewriteRule (submit-review)/(.*)$ review/submit.php?cid=$2 [L] RewriteRule (^review)/(.*) review/index.php?cid=$2 The problem, you may already see, is that /submit-review rewrites to /review, which in turn gets rewritten to index.php, thus my review submission page is lost in place of my index page. I figured that putting [L] would prevent the second rule being called, but it seems that it rewrites both urls in two seperate passes. I've also tried [QSE], and [S=1] I would rather not have to move my files into different folders to get the rewriting to work, as that just seems too much like bad practise. If anyone could give me some pointers on how to differentiate between these similar urls that would be great! Thanks (Ref: http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html)

• Apache mod_rewrite - forward domain root to subdirectory

  - by DuFace

  I have what I originally assumed to be a simple problem. I am using shared hosting for my website (so I don't have access to the Apache configuration) and have only been given a single folder to store all my content in. This is all well and good but it means that all my subdomains must have their virtual document root's inside public_html, meaning they effectively become a folder on my main domain. What I'd like to do is organise my public_html something like this: public_html/ www/ index.php ... sub1/ index.php ... some_library/ ... This way, all my web content is still in public_html but only a small fraction of it will be served to the client. I can easily achieve this for all the subdomains, but it's the primary domain that I'm having issues with. I created a .htaccess file in public_html with the following: Options +SymLinksIfOwnerMatch # I'm not allowed to use FollowSymLinks RewriteEngine on RewriteBase / RewriteCond %{REQUEST_URI} !^/www [NC] RewriteRule ^(.*)$ /www/$1 [L] This works fairly well, but for some strange reason www.example.com/stuff is translated into a request for www.example.com/www/stuff and hence a 404 error is given. It was my understanding that unless an 'R' flag was specified, mod_rewrite was purely internal so I can't understand why the request is generated as that implies (to me at least) redirection. I assumed this would be a trivial problem to solve as all I actually want to do is forward all requests for the root of www.example.com to a subdirectory, but I've spent hours searching for answers and none are quite correct. I find it difficult to believe I'm the only person to have this issue. I apologise if this question has been answered on here before, I did search and trawl but couldn't find an appropriate answer. Please could someone shed some light on this?

• What is the simplest way to map a folder on the file system to a url in Tomcat?

  - by Simon

  Here's my problem... I have a small prototype app (happens to be in Grails hosted on AWS) and I want to add the ability of the user to upload a few (max 10) images. I want to persist these images on disk on the server machine, in a folder location which is outside my WAR. I realise that there is probably a super-scalable solution involving more web servers and optimised static asset serving, but for the approximately 100 users I am likely to get, it's really not worth the effort and cost. So, what is the simplest way I can have a virtual folder from my url map to a physical folder on disk? I sort of want... http://myapp.com/static to map to a folder which I can configure e.g. /var/www/static so I can then have in my code... <img src="/static/user1/picture.jpg"/> I don't particularly mind whether the resulting physical folders are directly browsable. Security will eventually be an issue, but it isn't at the start. So, what are my options? I have looked at virtual hosts on the apache site, but it feels more complicated than I need. I don't want to use the Grails static rendering plugins.

• AIX 6.1 unable to build apache module

  - by user3715581

  In Aix 6.1/ Apache version 2.2.8 packaged as part of IBM WebSphere. We should have had mod_dumpio for this version but for some reasons IBM did not include it. So we are trying to build this module(in few many ways) but none of them worked. 1) Using apxs:- Failed with the "xlc_r" not found as compile option for libtool. So based on an article online, we changed to "gcc" and we have to remove -qmaxmem and -qHALT to make it work. Result we see a .lo created but LoadModule fails(unable to find .loader section). 2) Using gcc:- Command "gcc -fpic -DSHARED_MODULE -I -c mod_dumpio.c" After running this command, we can see .o file created and then we tried to execute "ld -Bshareable -o mod_dumpio.so mod_dumpio.o" whereas AIX complaining about -Bshareable so we tried using this command "gcc -shared -I -o mod_dumpio.so mod_dumpio.o" whereas the error was "libgcc_s" not found. Then we added -static-libgcc to the above command and it was not resolving .h file functions (Unknown symbols). From IBM AIX site, libgcc_s costs around $2k. We think our second approach may work but we dont know how to instruct gcc to look for .h files while building .so from .o. Any help is appreciated.

• Configure main domain and sub domain with diffrent resourcs in apache server

  - by Ritesh Patadiya

  I have an issue to creating a sub domain in apache server. Normally we can do that by following way. <VirtualHost *:80> ServerName www.maindomain.com ServerAlias *.maindomain.com DocumentRoot "/home/abc/xyz" <Directory "/home/abc/xyz"> AllowOverride All Allow from All </Directory> </VirtualHost> In above example both main and sub domain share same Directory. But my requirement is main domain have its own resource and rest of sub domains have other resource. I want to do something like this. <VirtualHost *:80> ServerName www.maindomain.com DocumentRoot "/home/abc/xyz" <Directory "/home/abc/xyz"> AllowOverride All Allow from All </Directory> </VirtualHost> <VirtualHost *:80> ServerName xyz.maindomain.com ServerAlias *.maindomain.com DocumentRoot "/home/ghi/pqr" <Directory "/home/ghi/pqr"> AllowOverride All Allow from All </Directory> </VirtualHost> Above thing didn't work for me

• Can't reinstall apache2

  - by Oetzi

  I recently was messing around with my apache config and wanted to reinstall so I could start from fresh. I followed some forum posts about resintalling apache2 and this ended up deleting my /etc/apache2 apache2 folder. Now matter how many thing I try I can't seem to do a full wipe of the apache install and then reinstall. sudo apt-get install apache2 or reinstall doesn't do anything. I can't seem to remove from synaptic either. Is there anything I can do to have a fresh apache install on my computer again? UPDATE: I now have files back but I can't start/restart apache. I get the error: ".: 49: Can't open /etc/apache2/envvars". Does anyone have a default set of apache settings or something similar that I could nick? Or is there something else I can do.

  ActiveMQ 5.7.0 In the activemq.log, I'm seeing this exception every 2 seconds: 2013-11-05 13:00:52,374 | DEBUG | Transport Connection to: tcp://127.0.0.1:37501 failed: org.apache.activemq.transport.InactivityIOException: Cannot send, channel has already failed: tcp://127.0.0.1:37501 | org.apache.activemq.broker.TransportConnection.Transport | Async Exception Handler org.apache.activemq.transport.InactivityIOException: Cannot send, channel has already failed: tcp://127.0.0.1:37501 at org.apache.activemq.transport.AbstractInactivityMonitor.doOnewaySend(AbstractInactivityMonitor.java:282) at org.apache.activemq.transport.AbstractInactivityMonitor.oneway(AbstractInactivityMonitor.java:271) at org.apache.activemq.transport.TransportFilter.oneway(TransportFilter.java:85) at org.apache.activemq.transport.WireFormatNegotiator.oneway(WireFormatNegotiator.java:104) at org.apache.activemq.transport.MutexTransport.oneway(MutexTransport.java:68) at org.apache.activemq.broker.TransportConnection.dispatch(TransportConnection.java:1312) at org.apache.activemq.broker.TransportConnection.processDispatch(TransportConnection.java:838) at org.apache.activemq.broker.TransportConnection.iterate(TransportConnection.java:873) at org.apache.activemq.thread.PooledTaskRunner.runTask(PooledTaskRunner.java:129) at org.apache.activemq.thread.PooledTaskRunner$1.run(PooledTaskRunner.java:47) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Due to this keyword InactivityIOException, the first thing comes to my mind is InactivityMonitor, but the strange thing is MaxInactivityDuration=30000: 2013-11-05 13:11:02,672 | DEBUG | Sending: WireFormatInfo { version=9, properties={MaxFrameSize=9223372036854775807, CacheSize=1024, CacheEnabled=true, SizePrefixDisabled=false, MaxInactivityDurationInitalDelay=10000, TcpNoDelayEnabled=true, MaxInactivityDuration=30000, TightEncodingEnabled=true, StackTraceEnabled=true}, magic=[A,c,t,i,v,e,M,Q]} | org.apache.activemq.transport.WireFormatNegotiator | ActiveMQ BrokerService[localhost] Task-2 Moreover, I also didn't see something like this: No message received since last read check for ... or: Channel was inactive for too (30000) long Do a netstat, I see these connections in TIME_WAIT state: tcp 0 0 127.0.0.1:38545 127.0.0.1:61616 TIME_WAIT - tcp 0 0 127.0.0.1:38544 127.0.0.1:61616 TIME_WAIT - tcp 0 0 127.0.0.1:38522 127.0.0.1:61616 TIME_WAIT - Here're the output when running tcpdump: Internet Protocol Version 4, Src: 127.0.0.1 (127.0.0.1), Dst: 127.0.0.1 (127.0.0.1) Version: 4 Header length: 20 bytes Differentiated Services Field: 0x00 (DSCP 0x00: Default;

• Eclipse Dynamic Web Project fails to load under WTP

  - by Cue

  When trying to run an Eclipse Dynamic Web Project under a Tomcat setup using WTP, it fails with the attached stacktrace. Checklist At the project properties, under "Java EE Module Dependencies" I have checked the "Maven Dependencies" At the wtp deploy directory, under lib indeed all dependencies are present (esp. struts-taglib-1.3.10.jar) On the other hand, if I package with maven and copy the war file under the webapps directory everything is working as normal. Specification Eclipse JEE Galileo SR2 (with WTP 3.1.1) Tomcat 6.0.26 Java(TM) SE Runtime Environment (build 1.6.0_17-b04-248-10M3025) Java HotSpot(TM) 64-Bit Server VM (build 14.3-b01-101, mixed mode) stacktrace org.apache.jasper.JasperException: Unable to read TLD "META-INF/tld/struts-html-el.tld" from JAR file "file:/Users/cue/Development/workspace/eclipse/.metadata/.plugins/org.eclipse.wst.server.core/tmp2/wtpwebapps/ticketing/WEB-INF/lib/struts-el-1.3.10.jar": org.apache.jasper.JasperException: Failed to load or instantiate TagExtraInfo class: org.apache.struts.taglib.html.MessagesTei at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:51) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:409) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:181) at org.apache.jasper.compiler.TagLibraryInfoImpl.<init>(TagLibraryInfoImpl.java:182) at org.apache.jasper.compiler.Parser.parseTaglibDirective(Parser.java:383) at org.apache.jasper.compiler.Parser.parseDirective(Parser.java:446) at org.apache.jasper.compiler.Parser.parseElements(Parser.java:1393) at org.apache.jasper.compiler.Parser.parse(Parser.java:130) at org.apache.jasper.compiler.ParserController.doParse(ParserController.java:255) at org.apache.jasper.compiler.ParserController.parse(ParserController.java:103) at org.apache.jasper.compiler.Compiler.generateJava(Compiler.java:185) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:347) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:327) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:314) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:589) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:313) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:260) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:298) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:852) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:588) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:489) at java.lang.Thread.run(Thread.java:637)
