• ASP.NET Website Administration Tool: Unable to connect to SQL Server database

  - by MedicineMan

  I am trying to get authentication and authorization working with my ASP MVC project. I've run the aspnet_regsql.exe tool without any problem and see the aspnetdb database on my server (using the Management Studio tool). my connection string in my web.config is: <connectionStrings> <add name="ApplicationServices" connectionString="data source=MYSERVERNAME;Integrated Security=SSPI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" providerName="System.Data.SqlClient" /> The error I get is: There is a problem with your selected data store. This can be caused by an invalid server name or credentials, or by insufficient permission. It can also be caused by the role manager feature not being enabled. Click the button below to be redirected to a page where you can choose a new data store. The following message may help in diagnosing the problem: Unable to connect to SQL Server database. In the past, I have had trouble connecting to my database because I've needed to add users. Do I have to do something similar here?

• Will this increase my Virtual private Server failing rate ?

  - by Spencer Lim

  Will this increase my Virtual private Server failing rate if i :- install Microsoft Window Server 2008 Enterprise install SQL server enterprise 2008 install IIS 7.5 install ASP.Net Mvc 2 install Microsoft Exchange << should live inside MWS2008 ? or standalone without OS? install Team foundation server << should live inside MWS2008 ? or standalone without OS? on one mini VPS with specification of DELL Poweredge R710 shared plan DDR3 ECC RAMs 16GB and -- 1GB for this VPS using DELL PERC 6i raid controller (this thing alone about 1.5k-2k) and the SAS HDD (15K RPM) (146GB) -- 33GB to this VPS each hdd is freaking fast over 300MB read / write possible with proper tuning the motherboard is a DELL and it has twin redundant PSU (870watt 85%eff) its running on Intel Xeon 5502 (Quad Core) x2 so about 8 physical proc (fairly share) is there any ruler to measure for this about one VPS can only install what what what service ? because of my resource is limited =.@ may i know if it is install in this way,maybe it seem like defeat the way of "VPS"... what will happen ? or any guideline on this issue (fully configuring the window server 2008 R2) ?

• Issues with ASP.NET via Apache/mod_mono on Ubuntu.

  - by Matthew Scharley

  I run an Ubuntu test server, and my deployment system is also Ubuntu. I've recently been trying to get ASP.NET to work on my test server so that we can take it live. I managed to get it installed, and configured properly, and my application is installed and running, but I can't get anything to work. The error I keep receiving is below, if anyone has any clue what might be going on, it would be greatly appreciated. Server Error in '/' Application Standard output has not been redirected or process has not been started. Description: HTTP 500. Error processing request.

• 403 Forbidden when Deploying asp.net 4.0 site to IIS 7

  - by Jordan

  So I have an EC2 instance running, the URL NoWeatherSurprises.com I have the DNS pointing there, and I set up a new site in IIS 7 and pointed it to a folder. I used Visual Studios Web Developer 2010 express to publish to this folder. It now has the binaries and such. However if I go to NoWeatherSurprises.com I get the welcome to IIS 7 screen. I'd expect to go to my application If I navigate to http://noweathersurprises.com/weather/ [weather was the folder I published to under wwwroot] I get a 403 forbidden. I have no idea why, I am guessing that it is trying to do a directory listing or something instead of launching my MVC Application. So 2 problems in summary. It is not pointing the domain to the folder directly and I need to add /weather I am getting a 403 forbidden instead of the results of my home controller with the index action. I am new to IIS 7, I had been using IIS 6 and had a lot less trouble setting it up, but I suspect that's my own fault and i am just missing something. Thanks in advance for any help

• IIS7 - how to place application in a folder inside application web site

  - by Nir

  I have a static web site with a blog (an asp.net application), the blog is in a subdirectory of the web site so: example.com/, example.com/Something.htm, example.com/folder/somefile.htm, etc. - are all static files example.com/blog, example.com/blog/categories.aspx, example.com/blog/2011/11/09/post-name.aspx, etc. - all go to the blog app I'm upgrading the static part of the web site to a dynamic site (also an asp.net application) and the blog is incompatible with the new app (the app needs handlers and modules loaded in web.config that don't work with the blog) Also, I have to keep all the old URLs the same - so I can't move the blog to a subdomain or the new app to a folder and the blog generates links based on its folder so clever redirection tricks wouldn't work. Is there a way to place an asp.net application in a folder inside another application (either as a real or virtual folder) so that the root web.config settings don't apply to the application folder? Or some other trick I didn't think of? The system is running IIS7 on Windows Server 2008 64bit, I have full control over the server's configuration. I can't modify the blog's source code but I can edit its web.config and other configuration. I can modify the source of the new application but I can't make it compatible with the blog (most of its usefulness comes from a 3rd party library that is not compatible with the blog). The blog in an asp.net 3.5 webforms application The new root application is an asp.net 4.0 mvc application

• What's the lowest cost, legal, Microsoft server stack you can assemble?

  - by McKAMEY

  Assuming that you have an app infrastructure that generally only requires: ASP.NET MVC / C# / .NET Database or NoSQL data store (must be accessible from C#) Here's the challenge to you server gods: What is the least expensive configuration that will allow you to deploy to production in a way that doesn't break any licensing rules? In what ways does this solution differ from the "standard" Microsoft deployment scenario? Where does this solution's performance break down once the app begins to scale? I'm not concerned about the hardware, only the server software itself. I would love to hear about any solutions you've personally put into production. Especially if they are unique alternatives. For ideas, consider some of the possible variations, a) any Microsoft server solutions where they have lowered the barrier to entry to compete with OSS, or b) any OSS alternatives to Microsoft products which perform at a similar level. An example of a): SQL Server 2008 Express Edition SP1 is a 100% free version of SQL Server which will scale to the needs of many smaller / early stage applications. An example of b): running the Mono Framework on Linux. An example of differing from the "standard" stack: running Mono on Linux will require a completely different server OS familiarity. None of the Windows-based knowledge really transfers. An example of breaking down under scale: SQL Server Express will only scale to 1GB of memory and 4GB of disk storage. After that point, the application will need to move to one of the paid versions of SQL Server.

• Sending Mail from Web App to Google Apps won't work - internal routing? VPS

  - by Charlino

  I've got a web application, www.mysuperwebapp.com, which sends out emails for various reasons - the contact us page is a good example. I am using google apps on the domain and I've setup a google apps group, Support ([email protected]), which I want the emails from the contact us page to go to. But the emails don't seem to be sending... I thought it could be that the groups security is a little tighter than normal email, so I change the contact us email to go to [email protected] - but they still didn't appear. So I'm guessing that it has something to do with internal routing and the messages aren't leaving the server/network at all. Eg Sending an email from the mysuperwebapp.com computer to a mysuperwebapp.com email address. I put an entry into the hosts file for 123.123.123.123 mysuperwebapp.com but that doesn't seem to have helped. Also, there doesn't seem to be anything of interest in the event log. What do I need to do? Or what do I need to get my VPS hoster to do? TIA, Charles Ps. The VPS is a Windows 2008 box with IIS7 and the default SMTP (IIS6?) server. The web app is ASP.NET MVC - not that that should matter.

• Server 2008R2 in Extra Small Windows Azure Instance?

  - by Shawn Eary

  Windows Azure hosting for an Extra Small (XS) Windows VM seems to come out to be about $10 a month right now. I think this XS instance gives you the equivalent of a 1 GHZ CPU with 768MB of RAM. I think the minimum requirements for Server 2008 is 1GHZ CPU with 512MB of RAM. Also, I think the minimum requirements for SQL Server Express is 1GHZ CPU with 256 MB of RAM and that the minimum requirements for Team Foundation Server Express 11 Beta is 2.2 GHZ CPU with 1 Gig of RAM (this 2.2 GHZ part could be a problem for my 1 GHZ XS VM...). Given the performance of the XS Azure instance, would I be able to install: a very basic MVC web site; a free instance of SQL Server Express; a free single user instance of Team Foundation Server Express 11 Beta and run the XS VM instance without serious crashing? I know there are other Shared WebHost providers that can provide these features for me, but those hosting providers have the following disadvantages: They sometimes cost a lot of money after all of the "addons" are in place They probably don't provide the level of security and employee integrity that Microsoft can provide They don't provide the total control that an Azure VM seems to provide

• How can I stop IIS7 (integrated mode) from reporting a 404 before I get a chance to handle it?

  - by Gary McGill

  I have an ASP.NET MVC 2 application running on IIS7 in integrated mode. I'm trying to do my own 404 handling, but IIS7 seems to be intercepting the error and returning its own 404 message to the client before I get a chance to handle it. I'm not having much luck coming at the problem from a programming perspective over on Stack Overflow, so I wondered if maybe it's a configuration problem. Is there something I have to do to tell IIS to let me handle my own errors? (I'm trying to use Application_Error in my global.asax but it's not even getting there). There is a custom error page defined (at the machine level, I think) for 404 but when I tried removing that it didn't really help - it simply showed a bald one-liner message instead. My code still didn't get a look in. Is it perhaps something to do with the routing? Maybe the "mysite.com/nosuchpage" URL isn't being routed to me and that's why I don't get a chance to intercept it? Do I need to do something so that ALL requests get routed through my app?

• IIS 7.5 fails to open database after computer machine on that database server is working restarts.

  - by Jenea

  Hi. I decided to post this question also here in case the issues we have is related to sql server. There is a problem that bother me for some time. I have an asp.net mvc that uses NHibernate for modeling the database. The infrastructure is the following: Windows 2008 R2 for all virtual machines. IIS 7.5 is working on one virtual machine. Sql Server 2008 is working on another virtual machine. We have couple of databases, two that stores application data and one that registers all unhandled exceptions. Sometimes virtual machine that hosts database server restarts (in the middle of the night, not quite sure about the reason) after that connection to the databases that stores application data is not working and as result there are thousands of unhandled exceptions that get registered in the third database. Important to mention that databases are accessible from Management Studio. The problem is solved by resetting IIS. Connetion are handled via NHibernateUtil class which opens and closes session at each request.

• 32bit dll not loading with Enable 32 Bit Applications on IIS 7.5

  - by Jon

  I have a MVC 3 Web Site referencing a 32 bit DLL. The OS is Windows 2008 R2 x64. The website is in the ASP.NET 4 App Pool. I have turned on Enable32Bit but it doesn't work. I get a Bad Image Exception but can't find out to turn this level of logging on in IIS. I have setup up a page that outputs whether it's running 32bit or 64bit and when I turn on/off the Enable32Bit on the AppPool I get the correct output. The website is also in Full Trust. I'm at a loss to try and and get it to work. I do know that it works on Win7 32bit. Can you suggest some things to try? UPDATE: I have just written a simple Windows Forms App with a button on it which calls my DLL. This was built with target of x86 and it worked fine so there is an issue with IIS or ASP.Net I think. UPDATE 2: Does it matter if the ASP.Net Pipeline is Clasic or Integrated? I've tried both but same problem but thought it was worth asking UPDATE 3: I found this question trying to do the same thing and he gave up which isnt too helpful!!

• Which default Database Systems come installed in Microsoft VS2010 Express?

  - by Tonygts

  Appreciate all advice 0n the following questions Which database systems (Ms SQL 2008, MS SQL Compact, or others) comes installed with VS2010 Express edition. SQL Server 2008 R2 Express is free, can we install and integrate with VS2010 Express? How to uninstall those database already come installed? I have installed VS2010 express on Windows 7; just VS2010 components (VB, C#, C++ and Web Developer) and without installing any other things like SQL Express. In the Console Panel-Program & Features' window, the installed list is shown below: Microsoft SQL Server 2008 Setup Support File Microsoft SQL Server 2008 Browser Microsoft SQL Server VSS Writer Microsoft SQL Server Database Publishing Wizard 1.4 Microsoft ASP.NET MVC2 - VWD Express 2010 Tools Microsoft SQL Server 2008 Management Objects Microsoft SQL Server Compact 3.5 SP2 ENU Microsoft SQL Server System CLR Types Microsoft Silverlight 3 SDK Microsoft ASP.NET MVC 2 Microsoft Visual Studio 2010 ADO.NET Entity Framework Tools Visual Studio 2010 Tools doe SQL Server Compact 3.5 SP2 ENU Web Deployment Tool Microsoft Visual Web Developer 2010 Express - ENU Microsoft Visual C++ 2010 Express - ENU Microsoft Visual C# 2010 Express - ENU Microsoft Visual Visual Basic 2010 Express - ENU Microsoft SQL Server 2008 As you can see, Microsoft SQL Server 2008 (last line) and near the top, Microsoft SQL Server Compact 3.5 SP2 ENU and many of their related SQL components such as Microsoft SQL Server 2008 R2 Management Objects are also installed. These are actually installed by installing VS2010 Express, but I have no idea how to use them or verify their valid existence from VS2010. Also, do I have to uninstall them before I install SQL Server 2008 R2, which is the latest version I believe? And what tool is needed to manage and create data source and tables?

• Linux Distro - GUI similar to Windows

  - by DeaconDesperado

  I am in the process of refurbing several older laptop machines for use by a couple college guys we have in training to learn basic web development in python. These are students who intern at my company and are hoping to do some work when the summer comes building simple client-oriented webapps (learning the basics of OOP, MVC webapp design in flask, etc.). We're trying to function as the "practical" side of their education. I would like to get them set up on these machines we have sitting about, but I'd like to use a linux distro that would have a gui that closely approximates what they are being compelled to use at school (windows.) I don't really have much of a preference as far as GUI goes since much of what we'll be learning together is accomplished on the command line. I just see this as an easier adjustment for them while they are still reliant on a graphical environment. In the past I'd go straight for Ubuntu, but since they started using the Unity GUI the responsiveness overall can be pretty clunky on older machines, especially since these machines (there are four of them) run the gambit on specs (though all are at least 1.0Ghz and none have anything better than basic integrated video.) Has anyone had to setup a similar working environment in Mint, bare Debian or Zorin? Thanks.

• RewriteRule causes POST data to get dumped before I can access it

  - by MatthewMcGovern

  I'm currently setting up my own 'webserver' (a Ubuntu Server on some old hardware) so I can have a mess around with PHP and get some experience managing a server. I'm using my own little MVC framework and I've hit a snag... In order for all requests to make it through the dispatcher, I am using: <Directory /var/www/> RewriteEngine On RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule . HomeProjects/index.php [L] </Directory> Which works great. I read on Stackoverflow to change the [L] to [P] to preserve post data. However, this causes every page to return: Not Found The requested URL <url> was not found on this server. So after some more searching, I found, "Note that you need to enable the proxy module, and the proxy_http_module in the config files for this to work." The problem is, I have no idea how to do this and everything I google has people using examples with virtual hosts and I don't know how to 'translate' that into something useful for my setup. I'm accessing my webserver via my public IP and forwarding traffic on port 80 to the web server (like I'm pretending I have a domain/server). How can I get this enabled/get post data working again? Edit: When I use the following, the server never responds and the page loads indefinately? LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so <Directory /var/www/> RewriteEngine On RewriteCond %{HTTP_REFERER} !^http://(.+\.)?82\.6\.150\.51/ [NC] RewriteRule .*\.(jpe?g|gif|bmp|png|jpg)$ /no-hotlink.png [L] RewriteCond %{REQUEST_URI} !\.(png|jpg|jpeg|bmp|gif|css|js)$ [NC] RewriteRule . HomeProjects/index.php [P] </Directory>

• Xamp on ubuntu serves php source for root url only

  - by mazaryk

  Hey, Okay, so installed xamp on my ubuntu machine, started it up and everything worked. Apache ran my php app just fine (including requests to the root url "/"). However, after the first reboot since installing, when I request "http://localhost/" apache serves up the index php page as a phtml source file. All other urls (like "http://localhost/login") work as expected. Backgound: The only modification I made to xamp was to setup a vhost for my app. The app uses an .htaccess file where I define some rewrite rules (the app is an MVC framework and all urls are rewritten to a single entry point php file). I'm using Xamp because I need php = 5.3.0. I know apache will serve up the source of a php file when it doesn't know to process php files. But the config does indeed have "AddType application/x-httpd-php .php" and as I said, the app works for all urls except the root "/" (and only since I've rebooted). The .htaccess file does contain a DirectoryIndex directive. xamp 1.3.7a Ubuntu 9.10 Any ideas?

• SSL configuration issue. SSL/IIS7 not loading all scripts/CSS on user's first visit

  - by Chris

  Hi all, Hopefully this isnt a tricky one. I've got a web app that doesn't load all javascript/css/images on the first visit. Second visit is fine. After approximately 2 minutes of inactivity the problem reoccurs. These problems only started occuring after the customer requested SSL be applied to the application. Ajax requests stop working after 2 minutes of activity despite a successful page load of all javascript elements. Application timeout is 30 minutes - like I said, everything was fine before SSL was applied. All javascript and CSS files use absolute URLS - e.g https://blablabla There appears to be no pattern as to why certain files arent loaded. The firebug Net output shows the status for the failed elements as 'Aborted'. For example, site.css and nav.css are in the same folder, are declared after each other in the head tag yet one is loaded and the other is not. Both will load fine after refreshing the page (unless roughly two minutes have passed). An Ajax request also shows as aborted after two minutes. However, if i do the request again the Ajax request will succeed. Almost as if the first request woke something up. None of these problems occur in Chrome Any ideas? FYI this is a .Net 4 C# MVC app running under IIS7 but I'm not sure its relevant since it works in Chrome. Everything worked fine before SSL was applied. Originally posted on stackoverflow but recommended to list here. Can provide additional details if necessary.

• What are the right questions to ask when deciding whether to use Chef or Puppet?

  - by John Feminella

  I am about to start a new project which will, in part, require deploying many identical nodes of approximately three different classes: Data nodes, which will run sharded instances of MongoDB. Application nodes, which will run instances of a Ruby on Rails application and an older ASP.NET MVC application. Processing nodes, which will run jobs requested by the application nodes. ALl the nodes will run on instances of Ubuntu 10.04, though they will have different packages installed. I have some familiarity with Chef from previous projects, though I don't consider myself an expert. In an effort to do due diligence, I have been investigating alternative possibilities. We have a number of folks in-house who are long-time Puppet users, and they have encouraged me to take a look. I am having trouble evaluating both choices, though. Chef and Puppet share many of the same domain terminology -- packages, resources, attributes, and so on, and they have a common history that stems from taking different approaches to the same problem. So in some sense they are very similar. But much of the comparison information I've found, like this article, is a little outdated. If you were starting this project today, what questions would you ask yourself to decide whether you should use Chef or Puppet for configuration management? (Note: I don't want answer to the question "Should I use Chef or Puppet?")

• Maven error: Unable to get resource / Server redirected too many times

• eclipse tomcat debug mode slow - pegs cpu

  - by andersonbd1

  Running Tomcat through eclipse works fine in non-debug mode, but not in debug mode. When I try to start the Tomcat server in debug mode, the console output looks fine for a while, but then starts slowing down and eventually just stops, pegging the cpu at 100%. I don't think it's relevant, but just in case - here's the console output right about when it starts slowing down and eventually stopping (by stopping I mean no more console output, but still 100% cpu). 2009-09-02 14:35:30,859 INFO NONE org.springframework.context.weaving.DefaultContextLoadTimeWeaver:72 - Found Spring's JVM agent for instrumentation 2009-09-02 14:35:49,562 INFO NONE org.springframework.beans.factory.support.DefaultListableBeanFactory:414 - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@ed889d: defining beans [... 2009-09-02 14:37:31,031 INFO NONE org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean:221 - Building JPA container EntityManagerFactory for persistence unit ... I tried everything I could think of to fix it: cleanesd tomcat working directory restarted eclipse restarted Windows refreshed/cleaned all projects I first had this problem last week using eclipse ganymede. I had been running fine in debug-mode for several months prior to this issue. I didn't make any significant changes to our project that would cause this. Eventually, I upgraded to eclipse galileo which solved my problem. Now 2 days later, I'm having the same problem in galileo. Like I said it works fine in non-debug mode. Any help is much appreciated. I should add that other things work in debug mode - for instance junit tests, so it is something specific to tomcat.

• Error 404: No target servlet configured for uri

  - by Aman

  Hi Experts, I just got done with a new Web module built with Spring Framework. Till now I was testing all the pages on my local machine using Tomcat. Today after I moved the application to Websphere, I am getting the following error: Error 404: No target servlet configured for uri is there anything I need to do in web.xml or somewhere?

• Android RestTemplate Ok on emulator but fails on real device

  - by Hossein

  I'm using spring RestTemplate and it works perfect on emulator but if I run my app on real device I get HttpMessageNotWritableException ............ nested exception is java.net.SocketException: Broken pipe Here is some lines of my code(keep in mind my app works perfect on emulator) ............ LoggerUtil.logToFile(TAG, "url is [" + url + "]"); LoggerUtil.logToFile(TAG, "NetworkInfo - " + connectivityManager.getActiveNetworkInfo()); ResponseEntity<T> responseEntity = restTemplate.exchange(url, HttpMethod.POST, requestEntity, clazz); ............. I know my device's network works perfect because all other applications on my device are working and also using device browser I'm able to connect to my server so my server is available. My server is up and running and my device is able to connect to my server so why I get java.net.SocketException: Broken pipe ?!!!!!!! Before I call restTemplate.exchange() I log NetworkInfo and it looks ok -type: WIFI -status: CONNECTED/CONNECTED -isAvailable: true Thanks in advance. Update: It is really weird Even if I use HttpURLConnection, it works perfectly on emulator but on real device I get 400 Bad Request Here is my code HttpURLConnection con = null; try { String url = ....; LoggerUtil.logToFile(TAG, "url [" + url + "]" ); con = (HttpURLConnection) new URL(url).openConnection(); con.setRequestMethod("POST"); con.setRequestProperty("Connection", "Keep-Alive"); con.setDoInput(true); con.setDoOutput(true); con.setUseCaches(false); con.connect(); LoggerUtil.logToFile(TAG, "con.getResponseCode is " + con.getResponseCode()); LoggerUtil.logToFile(TAG, "con.getResponseMessage is " + con.getResponseMessage()); } catch(Throwable t){ LoggerUtil.logToFile(TAG, "*** failed [" + t + "]" ); } in log file I see con.getResponseCode is 400 con.getResponseMessage is Bad Request

• JPA/JDO entity to XML XSD generator.

  - by h2g2java

  I am using JDO or JPA on GAE plugin in Eclipse. I am using smartgwt datasource, accepting an xsd. I would like to be educated how to generate an XSD from my jdo/jpa entity, vice versa. Is there a tool to do it? While datanucleas does all its magic enhancing in the Eclipse background, would I be able to somehow operate in a mode that would generate XSDs for me? Can Hibernate operate in an offline mode, to solely help me generate XSDs which I could use in GWT without deploying hibernate with my web-app? Can Hibernate even be capable of generating XSDs from entities, vice versa? Currently, I am about to write a utility to generate an xsd, given an entity class - but I am hoping I don't have to reinvent the wheel if it already exists. I am hoping people here could educate me on any available tools to ease my XSD generation. But btw, I am very wary of anything that uses Maven, because most people (like Spring) who write the Maven scripts and pom don't have the expertise to write it in a way that would spew out messages and verbosity appropriately to make it easy for me to locate model errors.

• AbstractMethodError when invoking createArrayOf, with postgresql 8.4 jdbc4 and JBoss 5.1GA

  - by Francesco

  Hi, when using this method public List<Field> getFieldWithoutId(List<Integer> idSections) throws Exception { try { Connection conn = this.getConnection(); Array arraySections = conn.createArrayOf("int4", idSections.toArray()); this.log.info("Recupero field"); List<Field> fields = this.getJdbcTemplate().query(getFieldWithoutIdQuery, new Object[] {arraySections},ParameterizedBeanPropertyRowMapper.newInstance(Field.class)); /*if (!conn.isClosed()) conn.close(); */ releaseConnection(conn); return fields; } catch (Exception e) { e.printStackTrace(); throw new Exception("Errore."); } } I have an exception at conn.createArrayOf("int4", idSections.toArray());. The exception is: javax.ejb.EJBException : Unexpected Error java.lang.AbstractMethodError: org.jboss.resource.adapter.jdbc.jdk5.WrappedConnectionJDK5.createArrayOf(Ljava/lang/String;[Ljava/lang/Object;)Ljava/sql/Array; postgresql-8.4-701.jdbc4.jar is in jboss/server/all/lib dir. Application is spring based with ejb3. When working locally with the same setup everything is fine. This only happens on a preproduction environment. Only difference is locally I have jboss run in default mode, in the other case there are 2 jbosses in all configuration. I can't track down the cause of this error. Could someone help me please?

• OLAP Web Visualization and Reporting Recommendations

  - by Gok Demir

  I am preparing an offer for a customer. They proide weekly data to different organizations. There is huge amount data suits OLAP that needed to be visualized with charts and pivot tables on web and custom reports will be built by non-it persons (an easy gui). They will enter a date range, location which data columns to be included and generate report and optionally export the data to Excel. They currently prepare reports with MS Excel with Pivot Tables and but they need a better online tool now to show data to their customers. Tables are huge and need of drill-down functionality. My current knowledge Spring, Flex, MySql, Linux. I have some knowledge of PostgreSQL and MSSQL and Windows. What is the easiest way of doing this project. Do you think that SSRP (haven't tried yet) and ASP.NET better suits for this kind of job. Actually I prefer open source solutions. Flex have OLAP Data Grid control which do aggregation on client side. JasperServer seems promising but it seems I need enterprise version (multiple organizations and ad hoc queries). What about Modrian + Flex + PostgreSQL solution? Any previous experience will be appreciated. Yes I am confused with options.
