  • tomcat resource missing, servlet not running

    - by user2837260
    import javax.servlet.*; import java.io.*; public class MyServlet implements Servlet { public void init(ServletConfig con) {} public void service(ServletRequest req, ServletResponse res) throws IOException,ServletException { res.setContentType("text/html"); PrintWriter out=res.getWriter(); String s="blah"; String s1="blah"; out.println("<html><body>"); if((s.equals(req.getParameter("firstname")))&&(s1.equals(req.getParameter("pwd")))) out.println("passwords match"); else out.println("password and name combo does not match"); out.println("</body></html>"); } public void destroy() {} public ServletConfig getServletConfig() { return null;} public String getServletInfo() { return null;} } this is my java file with the servlet class.its saved with the name MyServlet.java and so is the class file. and here is the xml file: <web-app> <servlet> <servlet-name>demoo</servlet-name> <servlet-class>MyServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>demoo</servlet-name> <url-pattern>/demo</url-pattern> </servlet-mapping> </web-app> i have made the folder as WEB-INF and then classes... WEB-INF also contains the .xml file but when i try to run the servlet , it says resource not found ps- i am already looking for the servlet with the name :demo localhost:8081/s1/demo* s1 is the war file * a html file in the war file seems to run fine on the server though. *

  • Use of select or multithread for almost 80 or more clients?

    - by Tushar Goel
    I am working on one project in which i need to read from 80 or more clients and then write their o/p into a file continuously and then read these new data for another task. My question is what should i use select or multithreading? Also I tried to use multi threading using read/fgets and write/fputs call but as they are blocking calls and one operation can be performed at one time so it is not feasible. Any idea is much appreciated. update 1: I have tried to implement the same using condition variable. I able to achieve this but it is writing and reading one at a time.When another client tried to write then it cannot able to write unless i quit from the 1st thread. I do not understand this. This should work now. What mistake i am doing? Update 2: Thanks all .. I am able to succeeded to get this model implemented using mutex condition variable. updated Code is as below: **header file******* char *mailbox ; pthread_mutex_t lock = PTHREAD_MUTEX_INITIALIZER ; pthread_cond_t writer = PTHREAD_COND_INITIALIZER; int main(int argc,char *argv[]) { pthread_t t1 , t2; pthread_attr_t attr; int fd, sock , *newfd; struct sockaddr_in cliaddr; socklen_t clilen; void *read_file(); void *update_file(); //making a server socket if((fd=make_server(atoi(argv[1])))==-1) oops("Unable to make server",1) //detaching threads pthread_attr_init(&attr); pthread_attr_setdetachstate(&attr,PTHREAD_CREATE_DETACHED); ///opening thread for reading pthread_create(&t2,&attr,read_file,NULL); while(1) { clilen = sizeof(cliaddr); //accepting request sock=accept(fd,(struct sockaddr *)&cliaddr,&clilen); //error comparison against failire of request and INT if(sock==-1 && errno != EINTR) oops("accept",2) else if ( sock ==-1 && errno == EINTR) oops("Pressed INT",3) newfd = (int *)malloc(sizeof(int)); *newfd = sock; //creating thread per request pthread_create(&t1,&attr,update_file,(void *)newfd); } free(newfd); return 0; } void *read_file(void *m) { pthread_mutex_lock(&lock); while(1) { printf("Waiting for lock.\n"); pthread_cond_wait(&writer,&lock); printf("I am reading here.\n"); printf("%s",mailbox); mailbox = NULL ; pthread_cond_signal(&writer); } } void *update_file(int *m) { int sock = *m; int fs ; int nread; char buffer[BUFSIZ] ; if((fs=open("database.txt",O_RDWR))==-1) oops("Unable to open file",4) while(1) { pthread_mutex_lock(&lock); write(1,"Waiting to get writer lock.\n",29); if(mailbox != NULL) pthread_cond_wait(&writer,&lock); lseek(fs,0,SEEK_END); printf("Reading from socket.\n"); nread=read(sock,buffer,BUFSIZ); printf("Writing in file.\n"); write(fs,buffer,nread); mailbox = buffer ; pthread_cond_signal(&writer); pthread_mutex_unlock(&lock); } close(fs); }

  • recursive program

    - by wilson88
    I am trying to make a recursive program that calculates interest per year.It prompts the user for the startup amount (1000), the interest rate (10%)and number of years(1).(in brackets are samples) Manually I realised that the interest comes from the formula YT(1 + R)----- interest for the first year which is 1100. 2nd year YT(1 + R/2 + R2/2) //R squared 2nd year YT(1 + R/3 + R2/3 + 3R3/) // R cubed How do I write a recursive program that will calculate the interest? Below is the function which I tried //Latest after editing double calculateInterest2(double start, double rate, int duration) { if (0 == duration) { return start; } else { return (1+rate) * calculateInterest2(start, rate, duration - 1); } }

  • Limit display/session resolution for machines @ VDI environment on RDS 2012

    - by WarP
    I have couple of windows 7 entprise virtual machines in collection as part of VDI environment - so users connecting to them through RDS 2012 web site. Is there any way to fix resolution of remote desktops, that user receives (instead of full screen all time) ? I've tried different group policies, but none of them are worked, probably because all those policies are for RDS sessions and not virtual desktops ... And i don't know how to limit resolution locally on win7 machine itself, so connecting users will receive fixed resolution.

  • Node.js server crashes , Database operations halfway?

    - by Ranadeep
    I have a node.js app with mongodb backend going to production in a week and i have few doubts on how to handle app crashes and restart . Say i have a simple route /followUser in which i have 2 database operations /followUser ----->Update User1 Document.followers = User2 ----->Update User2 Document.followers = User1 ----->Some other mongodb(via mongoose)operation What happens if there is a server crash(due to power failure or maybe the remote mongodb server is down ) like this scenario : ----->Update User1 Document.followers = User2 SERVER CRASHED , FOREVER RESTARTS NODE What happens to these operations below ? The system is now in inconsistent state and i may have error everytime i ask for User2 followers ----->Update User2 Document.followers = User1 ----->Some other mongodb(via mongoose)operation Also please recommend good logging and restart/monitor modules for apps running in linux

  • MySQL mistake with grant option

    - by John Tate
    I am unsure reading the MySQL documentation if creating a user with the GRANT option will give them the power to create users and grant privileges, or change the privileges of other users databases. I have been creating databases for users like this CREATE DATABASE user; USE user; GRANT ALL PRIVILEGES ON *.* TO 'user'@'localhost' IDENTIFIED BY 'password' WITH GRANT OPTION; Is this the best way of doing it or have I just given my users too much control? They are people I am hosting sites for. Thankfully at this point they are trustworthy. I use quotas. Edit: I have realized I have been granting users access to all databases. This is obviously stupid I should be using this: GRANT ALL PRIVILEGES ON database.* to 'user'@localhost' IDENTIFIED BY 'password' What is the simplest way to revoke privileges for every user except root so I can quickly end this catastrophic rookie mistake?

  • Using MongoDB + Redis + Apache on the same server in production?

    - by Dayson
    I intend to launch my web app using a 8 GB VPS. It uses MongoDB + Redis for storage/caching and Apache + PHP-FPM for serving requests. Could there be any issues with running Mongo + Redis + Apache on the same server? Would it make more sense to setup 2 x 4 GB VPS servers and keep Mongo on one and Redis + Apache on another? Should I just start with one server and worry about scaling horizontally later by delegating the existing server to Mongo in the future (due to its large RAM) and moving the web servers on to multiple smaller VPS'?

  • Is it possible to put an 8000 series socket-F Opteron into a dual-socket motherboard?

    - by René Kåbis
    Exactly what it says on the Tin. I have a dual-socket, socket-F motherboard in which I am looking to put two high-end quad-core Opterons, but the 2000 series are nearly double the price of the 8000 series on eBay. Can I just drop in a pair of 8000 series processors and be done with it, or are there processor-critical motherboard features that would be present on a quad(+)-socket motherboard that don’t exist on a dual-socket motherboard? Please elaborate or link to resources that can explain this further, as I am not adverse to research (and I am interested in the technical issues involved) I am probably using the wrong search terms, as Google failed to return anything within the first few dozen results.

  • Can't connect to smtp (postfix, dovecot) after making a change and trying to change it back

    - by UberBrainChild
    I am using postfix and dovecot along with zpanel and I tried enabling SSL and then turned it off as I did not have SSL configured yet and I realized it was a bit stupid at the time. I am using CentOS 6.4. I get the following error in the mail log.

  • Expire windows user (license) after some time according to first login instead of a solid expiration date

    - by smhnaji
    In a project, we have lots of Windows user that have bought licenses for 1 month, 2 month,... 1 year and so... CURRENT SITUATION (WHAT I DON'T WANT): When users are created and added to the OS, a solid expiration date is given. WHAT I WANT: Users' expiration date should be calculated automatically after first login. The user might not need his account right when purchases the license. In another words: When a license is purchased at Jan 1, he should use the license until Feb 1. No matter whether he really logs in or not. He cannot come Feb 5 and begin using his license because that has expired then. What I want is that when he comes at Feb 5 and begins using, the license update until March 5. Environment: Windows Server 2012

  • How can I configure myhostname to work with Postfix?

    - by John Kelly Ferguson
    I'm going through the process of setting up a Discourse forum on my server (Ubuntu 12.04 x64) and am getting stuck at the point where I have to configure mailers. I'm following Discourse's instructions and am stuck trying to configure postfix for Mandrill. It is says to check my fully-qualified domain name by typing hostname -f When I enter in hostname -f, I get localhost. As far as I know, entering in hostname -f should return mydomainname.com. When I just enter in hostname, I get mydomainname which is correct because that is what I set my hostname to in /etc/hostname. Looking at some of my other settings, my /etc/hosts file reads: 127.0.0.1 localhost mydomainname # The following lines are desirable for IPv6 capable hosts ::1 ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters And in my /etc/postfix/main.cf file, I have myhostname set like this: myhostname = mydomainname.mydomainname.com (Should this be myhostname = mail.mydomainname.com instead?) And mydestination is the following: mydestination = mydomainname.com, localhost, localhost.localdomain, localhost I'm not that familiar with configuring hostnames. I've been reading Postfix's instructions, but haven't been able to figure it out yet. Any help on how to get this to work would be greatly appreciated. Thanks.

  • Should I be using www. when setting up virtual hosts on apache?

    - by MAZUMA
    Does it matter whether or not I include the www. sub-domain when creating new virtual hosts on apache? So is this? /etc/apache2/sites-available/www.example.com better than this? /etc/apache2/sites-available/example.com I would assume I'd need to a2ensite either www.example.com or example.com. Depending on whichever method used? This might be a a fairly basic question But, I have no one else to ask. And, want to do it right.

  • Get IP or MAC addresses of Windows Multipoint Server 2012 stations?

    - by user1454265
    Is it possible to programmatically retrieve the IP or MAC address of a station assigned to a Windows MultiPoint Server 2012 host, using PowerShell or any other .NET or Windows API? Background: I'm developing a application to help set up USB-over-Ethernet zero clients in a WMS 2012 setup, bridging the PowerShell "WmsCmdlets" module (Microsoft.WindowsServerSolutions.MultipointServer.PowerShell.Commands.Library.WmsStation) and a third-party vendor API for configuring zero client IP address, etc. So far, I do not know any means of matching up the "stations" of the WmsCmdlets with the zero client objects in the vendor's API. Finding out the IP or MAC associated with a WMS station would do nicely, since I have this on the zero client API side. However, I haven't found any information I could use in the PowerShell WmsCmdlets module, such as Get-WmsStation which returns the following: Id : 1 Name : <my station name> IsAutoLogOn : False IsSplit : False CollabId : 0 RemoteConnectionServerName : VirtualMachineName : VirtualMachineId : AutoLogOnUserName : AutoLogOnPassword : DeviceTypes : {DT_Mouse, DT_Keyboard, DT_Audio, DT_MassStorage...} DeviceCounts : {2, 2, 0, 0...} ComputerName : <my WMS host server name> SessionId : 4294967295 SessionHostServer : <my WMS host server name>

  • Is it possible to create a self-signed intermediate CA for ssl?

    - by limilaw
    I am trying to create my own SSL hierarchy like: MyRootCA --MyIntermediateCA ----MyCert I have installed MyRootCA and MyIntermediateCA, but windows points out that MyIntermediateCA doesn't have the right to issue certs. Therefore it invalidates MyCert. i.stack.imgur.com/XDtXp.png i.stack.imgur.com/rZNQZ.png I am using sign.sh from mod_ssl package, which utilizes openssl ca command. I wonder if there is any parameter/option that grants MyIntermediateCA the right to issue sublevel certs?

  • How do I tunnel an HTTPS proxy through a virtual machine (VMWare)

    - by Kyle
    I have a personal setup at home using VMWare Workstation. I also have a set of Virtual Private Machines that run Squid, and therefore provide me HTTPS proxy tunnels. Using Proxifier, I can tunnel all traffic for given applications through these tunnels. However, I also have a few virtual machines for dev/staging/experimentation/etc. I generally just use NAT to provide Internet access to the machines, and if I need to use these proxies, I can just setup Proxifier (or a Linux equivalent) to pipe the traffic through them. No problem. But... I got to thinking: Wouldn't it be great if I could assign these proxy tunnels to a virtual machine, so that when I start up the VM, it has instant-on access through the tunnel and not my local connection? (EDIT: Of course, it would USE my local connection, but it would tunnel traffic through the proxy.) To be more clear: I want a solution that binds the proxy to a VM, so that when I start the VM, I don't have to use a proxy client to connect to the tunnel - I am already piping all traffic from that VM through that proxy. I did a bit of searching, and the closest thing I could find was this: How to route public static IP to a virtual machine on a vmware ESXi host? Which wasn't all that applicable. The proxies are protected by user/pass but do not filter by IP. Again, they are HTTPS proxies setup through Squid. Any ideas on how to make this happen? Thanks a ton.

  • How can I "filter" postfix-generated bounce messages?

    - by Flimzy
    We are using postfix 2.7 and custom SMTPD (based on qpsmtpd) in highly customized configuration for spam filtering. We have a new requirement to filter postfix-generated bounces through our custom qpsmtpd process (not so much for content filtering, but to process these bounces accordingly). Our current configuration looks (in part) like this: main.cf (only customizations shown): 2526 inet n - - - 0 cleanup pickup fifo n - - 60 1 pickup -o content_filter=smtp:127.0.0.2 Our smtpd injects messages to postfix on port 2526, by speaking directly to the cleanup daemon. And the custom pickup command instructs postfix to hand off all locally-generated mail (from cron, nagios, or other custom scripts) to our custom smtpd. The problem is that this configuration does not affect postfix generated bounce messages, since they do not go through the pickup daemon. I have tried adding the same content_filter option to the bounce daemon commands, but it does not seem to have any effect: bounce unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 defer unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 trace unix - - - - 0 bounce -o content_filter=smtp:127.0.0.2 For reference, here is my main.cf file, as well: biff = no # TLS parameters smtpd_tls_loglevel = 0 smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache smtp_tls_security_level = may mydestination = $myhostname alias_maps = proxy:pgsql:/etc/postfix/dc-aliases.cf transport_maps = proxy:pgsql:/etc/postfix/dc-transport.cf # This is enforced on incoming mail by QPSMTPD, so this is simply # the upper possible bound (also enforced in defaults.pl) message_size_limit = 262144000 mailbox_size_limit = 0 # We do our own message expiration, but if we set this to 0, then postfix # will try each mail delivery only once, so instead we set it to 100 days # (which is the max postfix seems to support) maximal_queue_lifetime = 100d hash_queue_depth = 1 hash_queue_names = deferred, defer, hold I also tried adding the internal_mail_filter_classes option to main.cf, but also tono affect: internal_mail_filter_classes = bounce,notify I am open to any suggestions, including handling our current content-filtering-loop in a different way. If it's not clear what I'm asking, please let me know, and I can try to clarify.

  • vsftpd with pam_winbind.so

    - by David
    I'm trying to setup vsftpd to use logins from our domain. I want the ftp users to be able to login using their active directory username/password and have be able to have full access to /media/storage/ftp/username. I setup pptp using winbind and it is working fine, so I belive the issue is with vsftpd and pam. The ftp server runs and gives 530 for the login. I turned on debug for the pam module, but I see nothing in the syslog. Vsftp only logs a wrong login in its log. /etc/pam.d/vsftpd auth required pam_winbind.so debug /etc/vsftpd.conf listen=YES listen_ipv6=NO connect_from_port_20=YES anonymous_enable=NO local_enable=YES write_enable=YES xferlog_enable=YES idle_session_timeout=600 data_connection_timeout=120 nopriv_user=ftp ftpd_banner=Welcome to Scantiva!

  • Ubuntu upstart hangs on interactive start & stop

    - by danorton
    How do I get Ubuntu upstart to not hang on interactive start & stop? I have created many upstart scripts that work fine during init, but often hang when I enter them at the console. If I CTRL+C out, all that happens is that the job changes state. The script is never run. I’m running Ubuntu Lucid on a Xen virtual server with a Linux 2.6.39 kernel. Below is merely a representative example of many scripts that behave this way: description "apache2" start on local-filesystems \ and (net-device-up IFACE=lo) \ and (runlevel [2345]) stop on runlevel [016] respawn respawn limit 10 5 expect daemon script . /etc/apache2/envvars /usr/sbin/apache2ctl start end script

  • Left click and enter not working

    - by user1981338
    Sometimes when I turn on my homemade desktop computer (running 64-bit Windows 7), the left mouse click and enter key doesn't work. They work well in BIOS, as well as on the Windows 7 BCD and login screen. Usually, restarting the computer solves the problem. Why does this keep happening? I've tried: Using other USB ports Refreshing, repairing and reinstalling drivers Changing mouse settings Refreshing mouse profiles My keyboard is a Logitech G510, and my mouse is a Razer Lanchesis 5600. Both work without problems in Ubuntu 12.04 and Windows 8.1 Preview, and I've been using both on my 64-bit Windows 7 homemade desktop without problems for about a year and a half. I encountered the problems yesterday.
