• How to display Google Online Spreadsheets in browser using Servlets

  - by Javenerd

  I am looking for a solution on how to display Google spreadsheets in web page using Servlets. Something like this: user logs into the application and then opts to create a new google spreadsheet. I just want to know how to display google spread sheet in web application using servlets. I don't want to create a spreadsheet in my account and then make it shared and publish the URL in my web application. This does not fit my requirement. Can anyone help me how and where to start with this? PS: Same question asked in the below forums: http://www.google.com/support/forum/p/apps-apis/thread?tid=184ba3b87a181ac8&hl=en http://forums.sun.com/thread.jspa?threadID=5433760

• Include params/request information in Rails logger?

  - by Dan Hill

  Hi everyone, I'm trying to get some more information into my Rails logs, specifically the requested URI or current params, if available (and I appreciate that they won't always be). However I just don't seem able to. Here's what I've done so far: #config/environments/production.rb config.logger = Logger.new(config.log_path) config.log_level = :error config.logger.level = Logger::ERROR #config/environment.rb class Logger def format_message(level, time, progname, msg) "**********************************************************************\n#{level} #{time.to_s(:db)} -- #{msg}\n" end end So I can customize the message fine, yet I don't seem to be able to access the params/request variables here. Does anyone know if this is possible, and if so how? Or if there's a better way to get this information? (Perhaps even something Redis based?) Thanks loads, Dan

• Linq to SQl over WCF Timesout after several calls

  - by Redeemed1

  I have a L2S Repository class which instantiates the L2S DataContext in its constructor. The repository is instantiated at run time (using Unity) in a service hosted in IIS with WCF. When I run up the client MVC applicaton the calls to the backend WCF service work for a while and then timeout. I suspected perhaps a database issue as I was depending on IIS garbage collection to dispose of unused DataContext instances in the IIS host but when I checked the characteristics of the problem I notice the following: The client makes the call to WCF but the WCF service does not respond. Next, the client times out Some time later (several minutes) the service actually executes the request by instantiating the repository and servicing the call. I have checked both client and server traces logs and only the client shows WCF errors (the timeout error). Where should I look? Is it something in WCF or is L2S possibly blocking with unfreed conenctions, resources etc.? Many thanks Brian

• Legacy application with JDBC and JNDI REALM authentication

  - by KB

  Hello All, My application currently relies on JDBC realm authentication. Recent needs have forced us to think about having LDAP authentication as well. We are thinking about using Active Directory for both authentication as well as authorization (roles). As a standalone test, I was able to authenticate my application with AD. But here is the confusion I have going forward. If the user chooses LDAP authentication when he logs in, I authenticate the user with AD, get the user's roles and do I replicate(create a new) windows user in my database?. I have to have the user in the database, because many parts of the application is designed to retrieve the user from database If the users chooses local login, I still should have JDBCRealm somewhere that I should use to authenticate the user. Is it possible to have multiple realms in tomcat? (I sort of know it is possible, but havent seen much documentation around it) Any thoughts, comments, suggestions would immensely help me Thanks K

• Can't get Logback Eclipse plugin to display output

  - by Zombies

  I followed these instructions here: http://logback.qos.ch/consolePlugin.html I have the correct and found logback.xml, it is set up correctly, and the port is listening. Nothing shows up with logger.error("Test"); It logs to sysout fine when I remove logback.xml, which shows to me that the logback is working fine. I installed the plugin on linux by moving it to /usr/lib/eclipse/plugins ...The window shows up, but no logging events are showing up. I also added a catch all ACCEPT filter like on that link. Perhaps this is a linux permission issue?

  - by Samuh

  I am trying to open a remote Stream of a JPEG image and convert it into a Bitmap object: BitmapFactory.decodeStream( new URL("http://some.url.to/source/image.jpg") .openStream()); The decoder returns null and in the logs I get the following message: DEBUG/skia(xxxx): --- decoder->decode returned false Note: 1. the content length is non-zero and content type is image/jpeg 2. When I open the URL in browser I can see the image. What is that I am missing here? Please help. Thanks.

• Firefox session cookies

  - by meandmycode

  Generally speaking, when given a cookie that has no expiration period, modern browsers will consider this cookie to be a 'session cookie', they will remove the cookie at the end of the browsing session (generally when the browser instance closes). IE, Opera, Safari and Chrome all support this behavior. However firefox (3.0.9 latest proper release) appears not to follow this rule, from what I can tell it doesn't expire the cookies when the browser is closed, or when the user logs off or restarts the OS.. So, why does firefox refer to these as session cookies, when they last aparently indefinitely? Does anyone know how Firefox handles session cookie expiration?

• log4net versus TraceSource

  - by Paul Stovell

  In this thread many people have indicated that they use log4net. I am a fan of TraceSources and would like to know why log4net is used. Here is why I like trace sources: Pluggable listeners - XML, TextFile, Console, EventLog, roll your own Customisable trace switches (error, warning, info, verbose, start, end, custom) Customisable configuration The Logging Application Block is just a big set of TraceListeners Correlation of activities/scopes (e.g., associate all logs within an ASP.NET request with a given customer The Service Trace Viewer allows you to visualize events against these activities individually All of it is configurable in app.config/web.config. Since the .NET framework internally uses TraceSources, it also gives me a consistent way of configuring tracing - with log4net, I have to configure log4net as well as TraceSources. What does log4net give me that TraceSources don't (or that couldn't be done by writing a couple of custom TraceListeners)?

• To stop returning through SSH using Pexpect

  - by chrissygormley

  Hello, I am trying to use pexpect to ssh into a computer but I do not want to return back to the original computer. The code I have is: #!/usr/bin/python2.6 import pexpect, os def ssh(): # Logs into computer through SSH ssh_newkey = 'Are you sure you want to continue connecting' # my ssh command line p=pexpect.spawn('ssh [email protected]') i=p.expect([ssh_newkey,'password:',pexpect.EOF]) p.sendline("password") i=p.expect('-bash-3.2') print os.getcwd() ssh() This allows me to ssh into the computer but when I run the os.getcwd() the pexpect has returned me to the original computer. You see I want to ssh into another computer and use their environment not drag my environment using pexpect. Can anyone suggest how to get this working or an alternative way. Thanks

• Container Options in AWS Elastic Beanstalk

  - by Sangram Anand

  We have deployed a java webapplication in Elastic Beanstalk with the minimum instance count 1 and max instance count 2 for Autoscaling. The custom AMI we are using is c1.medium with Sun JDK 6. The environment status changed to yellow and then red. After checking into the log file from the snapshot logs we found a exception - Caused by: java.lang.OutOfMemoryError: Java heap space. Assuming this could be one of the possible reason for the Environment failure. The settings that we have configured in the Environment Container option are Initial JVM Heap Size (MB) - 256M Maximum JVM Heap Size (MB) - 512m The maximum heap size the java virtual machine will ever consume, specified on the JVM launch command line using -Xmx. Maximum JVM Permanent Generation Size (MB) - 512m Should i increase the Heap size from 512m to more or is it fine.

• jquery-Ajax call on tornado handlers waits for pervious ajax call to return

  - by harshh

  Hey All. I recently started testing TornadoWeb for a home-project, which uses jquery getJSON function to call my tornado handlers. And found something strange, which i seek an explanation for. I fire an ajax request for Handler1 on tornado, and in some cases request for Handler2 is initiated before Handler1 returns. It appears from development-server logs, and firebug console-debugging, that Handler2 request waits for Handler1 request to finish, and then return. So basically, XHR call is waiting for earlier XHRs. They are supposed to be asynchronous/non-blocking right?? Or am i missing something. You can check the test-case environment called testtornado at http://github.com/harshh/Harsh-Projects/ with main.py as server triggering file. I would appreciate help from anyone who can throw some light on this.

• How to calculate bandwidth consumption for a Hosting Account using C# in ASP.Net Application?

  - by Steve Johnson

  HI all, I am working on SaaS Hosting Software. a large number of sites are hosted on the server. I am trying to calculate bandwidth consumption, (bytes transferred in and out) using C#, described Here using the MS Log Parser. In the above case, if the log files are deleted by the user or any administrator even, the bandwidth calculation will not be possible. Q1: *What is the standard way to measure the Bandwidth for various Hosting accounts (of websites) on a single server?* Q2: *If Log parser mechanism (as described above) is used, then how to take care of the security issue? Is there some system directory or event viewer logs or something which cannot be deleted except by the System account and contains bandwidth data?* Please point me in the right direction. Thanks

• PHP Session when using desktop app

  - by Jonathan

  In this question I asked how to POST to a php file form a vb.net app: http://stackoverflow.com/questions/2615335/post-to-webpage-in-vb-net-win-forms-desktop-not-asp-net So now I've logged in the user user by posting their username and password to the php file, the php file then does security/checks they exist/etc and if both username and password are correct is stores the user ID in a session variable. Now if the vb.net app tries to download data off a page which needs the user to logged in, it checks this by doing: if (!isset($_SESSION['uid'])) { header("Location: index.php"); } However after having logged correctly in the app the session variable is not set. How does session work with a vb.net app like this? When the user logs in successfully should I download the user id and keep it in the vb.net app and then post it to each page that requires authentication?

• ASP.NET FormsAuthentication Cookie Problem

  - by Niels Bosma

  We use FormAuthentication to manage logins and I have a case where a customer complains where he can login from one computer but to from another. I can see in my logs that his authentican is successfull but he gets bumped back to the login page. I can reproduce the symptons by disabling cookies so I asked the customer to test if cookies are enabled on http://www.tempesttech.com/cookies/cookietest1.asp, but this came out positive. What have I missed? Is there any antivirus/security software that can mess up (ASP.NET) cookies? The user is using IE7 and claims to have F-secure installed.

I only need to get the exact results of l_counts. Thank you Jordan Pagaduan

• Changing database structure at runtime with Entity Framework?

  - by Teddy

  Hi. I have to write a solution that uses different databases with different structure from the same code. So, when a user logs to the application I determine to which database he/she is connected to at runtime. The user can create tables and columns at any time and they have to see the change on the fly. The reason that I use one and the same code the information is manipulates the same way for the different databases. How can I accomplish this at runtime? Actually is the Entity Framework a good solution for my problem? Thanks in advance.

• Are there tools that would be suitable for maintaining a changelog for a Cabal Haskell package?

  - by Norman Ramsey

  I'm working fast and furiously on a new Haskell package for compiler writers. I'm going through many minor version numbers daily, and the Haskell packaging system, Cabal, doesn't seem to offer any tools for updating version numbers or for maintaining a change log. (Logs are going into git but that's not visible to anyone using the package.) I would kill for something equivalent to Debian's uupdate or dch/debchange tools. Does anyone know of general-purpose tools that could be used to increment version numbers automatically and add an entry to a change log?

• Finding new IP in a file

  - by Gary

  Hello. I have a file of IP addresses called "IPs". When I parse a new IP from my logs, I'd like to see if the new IP is already in file IPs, before I add it. I know how to add the new IP to the file, but I'm having trouble seeing if the new IP is already in the file. !/usr/bin/python from IPy import IP IP = IP('192.168.1.2') f=open(IP('IPs', 'r')) #This line doesn't work f=open('IPs', 'r') # this one doesn't work for line in f: if IP == line: print "Found " +IP +" before" f.close() In the file "IPs", each IP address is on it's own line. As such: 222.111.222.111 222.111.222.112 Also tried to put the file IPs in to an array, but not having good luck with that either. Any ideas? Thank you, Gary

• Jabber integration into site and multiple domains

  - by Jamie

  Hi all, I'm creating a centralised web product, i.e. a customer gets assigned a personal domain, for example company1.example.com or company2.example.com and can then use our service. I'm planning to integrate a jabber service into the website. I have already found a decent jabber client library which I can use for the site. I know that jabberd2 uses mysql, which is perfect because I want to use the web interface to add users, delete users, view message logs etc. However, my problem is when I have two companies or more. I would like a jabber server which can host multiple domains, i.e. jabber.company1.example.com, jabber.company2.example.com Do you have any experience of this? And do you know of a good jabber server which will do this? Any help would be hugely appreciated!

• Admob ads will not display when placed inside a tabview

  - by smith324

  I've been trying to get my ads to display in this type of layout. Tabs - LinearLayout - ListView - header. The header is set via addHeaderView and is displaying normally. If I were to move the ads anywhere else they display normally (so its not a setup issue). Using ads in the header of a listview works fine in my other projects. So this seems to be a very specific problem, the ads simply refuse to display when placed in the header of a listview inside a tabhost. My logs show no activity from admob at all. There is either a bug here or limitation of the sdk. Does anyone have any experience or insight into this issue? EDIT I found the solution. It actually had to do with padding that was in the root of my Tabview. For more checkout my answer here

• How to prevent a javascript/backbone.js cloned model from sharing attributes

  - by user540727

  I'm working with backbone.js models, so I don't know if my question is particular to the way backbone handles cloning or if it applies to javascript in general. Basically, I need to clone a model which has an attribute property assigned an object. The problem is that when I update the parent or clone's attribute, the other model is also updated. Here is a quick example: var A = Backbone.Model.extend({}); var a = new A({'test': {'some': 'crap'}}); var b = a.clone(); a.get('test')['some'] = 'thing'; // I could also use a.set() to set the attribute with the same result console.log(JSON.stringify(a)) console.log(JSON.stringify(b)) which logs the following: {"test":{"some":"thing"}} {"test":{"some":"thing"}} I would prefer to clone a such that b won't be referencing any of its attributes. Any help would be appreciated.

• ETW tracking from .net, user mode and driver

  - by Jack Juiceson

  Hi everyone, We have an application that parts of it are in .net, c++ usermode and C++ drivers. The application is divided into several executables that run on demand and communication with each other using LPC(the processes run in different sessions(winlogon)). Currently We have a home written logging service to which .net and c++ usermode communicate by sending LPC messages. The driver uses DbgPrint and is not always enabled, as it causes the code to run 30% slower(we have lots of logging). I want to have all the logs written in one place and preferably not writing the logger myself(I love log4cpp and log4net). The requirement is to write from all the executables and drivers into one place and to have minimal overhead. I have read that ETW is way to go, however I wasn't able to find already written logger that uses it like log4cpp or log4net. So basically my questions is, do you know if there is already implemented ETW appender for log4cpp and log4net I can use ?

• Best practice for storing global data in PHP?

  - by user281434

  Hi I'm running a web application that allows a user to log in. The user can add/remove content to his/her 'library' which is displayed on a page called "library.php". Instead of querying the database for the contents of the users library everytime they load "library.php", I want to store it globally for PHP when the user logs in, so that the query is only run once. Is there a best practice for doing this? fx. storing their library in an array in a session? Thanks for your time
