• Selectively allow unsafe html tags in Plone

  - by dhill

  I'm searching for a way to put widgets from several services (PicasaWeb, Yahoo Pipes, Delicious bookmarks, etc.) on the community site I host on Plone (currently 3.2.1). I'm looking for a way to allow a group of users to use dangerous html tags. There are some ways I see, but I don't know how to implement those. One would be changing safe_html for the pages editors own (1). Another would be to allow those tags on some subtree (2). And yet another finding an equivalent of "static text portlet" that would display in the middle panel (3). We could then use some of the composite products (I stumbled upon Collage and CMFContentPanels), to include the unsafe content on other sites. My site has been ridden by advert bots, so I don't want to remove the filtering all together. I don't have an easy (no false positives) way of checking which users are bots, so deploying captcha now wouldn't help either. The question is: How to implement any of those solutions? (I already asked that on plone mailing list without an answer, so I thought I would give it another try here.)

• Customizing the TFS 2008 build sequence to avoid compilation and deploy SSRS

  - by Andrew

  I'm trying to create a CI process for SQL Server Reporting Services. I am fairly new to TFS but quite experienced with MSBuild. In the past I've used a combination of MSBuild with Team City so the whole build process is more or less custom. Here lies the start of my problems, as the solution I am deploying only contains Report Server projects (rds), no compilation is required. I thought that I would override the the first default task that TFS runs (EndToEndIteration) to override the default TFS build sequence and inject my own. The first snag that I have come across is that the build always fails, how can I set the status of the build to success? Currently the EndToEndIteration task is very light and only has a message. Is this the best method to create a custom build process in TFS where compilation is not required? Or should I use the default sequence and override one of the hook tasks mentioned in http://msdn.microsoft.com/en-us/library/aa337604%28VS.80%29.aspx (ie: AfterCompile) The core steps that I'd like to achieve are: Bundle the RDL and datasource files Connect to the host server to register/deploy the reports Re-apply any subscriptions that previously existed Run tests to verify the deployment succeeded and is returning results as expected I have found another article on Report services deployment: http://stackoverflow.com/questions/88710/reporting-services-deployment But it doesn't mention the best practice for customizing the standard build process. Any help would be appreciated.

• how to make war file take up less memory

  - by Myy

  I need help on how to decrease the memory usage of my web app. so I can fit more into my webserver. so I'm building a java web app with JSF 2.0 developing in eclipse helios and running on an Apache tomcat Server. And I have a dedicated virtual server with a tomcat aswell where I deploy these war files. the webApp is about 35MB in size ( it has a lot of jars and such) but when I deploy it to my tomcat webserver, I can see it takes about 300MB of RAM, is this normal? my dedicated server only has 2GB of ram from which normally have 1 to use. so I as soon as I deploy 3 apps I get an OOM error, I've gotten permgen OOM and a out of swamp Memory error; to fix this I upped my MaxPermGen to about a gig and resytarted the server to get back some swamp space. so I tried deploying smaller older apps ( about 15MB) and they take up waay less memory. If I have 1 GB of ram I want to be able to fit more apps into my webserver without getting any OOM Errors. now I found this stack overflow Question, Can that be applied to my case? and if so, which are the common folders in the tomcat server? anyone done this before or have a different more effective, not so complicated approach? Any ideas, and or commets are more than appreciated. Thanks! Myy

• Game engine deployment strategy for the Android?

  - by Jeremy Bell

  In college, my senior project was to create a simple 2D game engine complete with a scripting language which compiled to bytecode, which was interpreted. For fun, I'd like to port the engine to android. I'm new to android development, so I'm not sure which way to go as far as deploying the engine on the phone. The easiest way I suppose would be to require the engine/interpreter to be bundled with every game that uses it. This solves any versioning issues. There are two problems with this. One: this makes each game app larger and two: I originally released the engine under the LGPL license (unfortunately), but this deployment strategy makes it difficult to conform to the rules of that license, particularly with respect to allowing users to replace the lib easily with another version. So, my other option is to somehow have the engine stand alone as an Activity or service that somehow responds to intents raised by game apps, and somehow give the engine app permissions to read the scripts and other assets to "run" the game. The user could then be able to replace the engine app with a different version (possibly one they made themselves). Is this even possible? What would you recommend? How could I handle it in a secure way?

• Debugging a Google Web Toolkit application that has an error when deployed on Google App Engine

  - by gerdemb

  I have a Google Web Toolkit application that I am deploying to Google App Engine. In the deployed application, I am getting a JavaScript error Uncaught TypeError: Cannot read property 'f' of null. This sounds like the JavaScript equivalent of a Java NullPointerException. The problem is that the GWT JavaScript is obfuscated, so it's impossible to debug in the browser and I can't reproduce the same problem in hosted mode where I could use the Java debugger. I think the reason I'm only seeing the error on the deployed application is that the database I'm using on the GAE server is triggering something differently than the test database I'm using during testing and development. So, any ideas about the best way to proceed? I've thought of the following things: Deploy a non-obsfucated version of my application. Despite a lot of Googling, I can't figure out how to do this using the automatic deploy script provided with the Google Eclipse Plugin. Does anyone know? Download and copy my GAE data to the local server Somehow point my development code to use the GAE server for data instead of the local test database. This seems like the best idea... Can anyone suggest how to proceed here? Finally, is there a way to catch these JavaScript errors on the production server and log them somewhere? Without logging, I won't have anyway to know if my users are having errors that don't occur on the server. The GWT.log() function is automatically stripped out of the production code...

• What are simple instructions for creating a Python package structure and egg?

  - by froadie

  I just completed my first (minor) Python project, and my boss wants me to package it nicely so that it can be distributed and called from other programs easily. He suggested I look into eggs. I've been googling and reading, but I'm just getting confused. Most of the sites I'm looking at explain how to use Python eggs that were already created, or how to create an egg from a setup.py file (which I don't yet have). All I have now is an Eclipse pydev project with about 4 modules and a settings/configuration file. In easy steps, how do I go about structuring it into folders/packages and compiling it into an egg? And once it's an egg, what do I have to know about deploying/building/using it? I'm really starting from scratch here, so don't assume I know anything; simple step-by-step instructions would be really helpful... These are some of the sites that I've been looking at so far: http://peak.telecommunity.com/DevCenter/PythonEggs http://www.packtpub.com/article/writing-a-package-in-python http://www.ibm.com/developerworks/library/l-cppeak3.html#N10232 I've also browsed a few SO questions but haven't really found what I need. Thanks!

• PropertyPlaceholderConfigurer vs Filters -- Spring Beans

  - by John

  Hi there. I've got a question regarding the difference between PropertyPlaceholderConfigurer (org.springframework.beans.factory.config.PropertyPlaceholderConfigurer) and normal filters defined in my pom.xml. I've been looking at examples, and it seems that even though filters are defined and marked to be active by default in the pom.xml they still make use of PropertyPlaceholderConfigurer in Spring's applicationContext.xml. This means that the pom.xml has a reference to a filter-LOCAL.properties while applicationContext.xml has a reference to application.properties and they both contain the same settings. Why is that? Is that how it is supposed to be done? I'm able to run the goal mvn jetty:run without the application.properties present, but if I add settings to the application.properties that differ from the filter-LOCAL.properties they don't seem to override. Here's an example of what I mean: pom.xml <profiles <profile <idLOCAL <activation <activeByDefaulttrue </activation <properties <envLOCAL </properties </profile </profiles applicationContext.xml <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer" <property name="locations" <list <valueclasspath:application.properties </list </property <property name="ignoreResourceNotFound" value="true"/ </bean <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close" <property name="driverClassName" value="${jdbc.driver}"/ <property name="url" value="${jdbc.url}"/ <property name="username" value="${jdbc.username}"/ <property name="password" value="${jdbc.password}"/ </bean an example of the content of application.properties and filters-LOCAL.properties jdbc.driver=org.postgresql.Driver jdbc.url=jdbc:postgresql://localhost/shoutbox_dev jdbc.username=tester jdbc.password=tester Can I remove the propertyConfigurer from the applicationContext, create a PROD filter and disregard the application.properties file, or will that give me issues when deploying to the production server?

• SVN marking file production ready

  - by dan.codes

  I am kind of new to SVN, I haven't used it in detail basically just checking out trunk and committing then exporting and deploying. I am working on a big project now with several developers and we are looking for the best deployment process. The one thing we are hung up on is the best way to tag, branch and so on. We are used to CVS where all you have to do is commit a file and tag it as production ready and if not that code will not get deployed. I see that SVN handles tagging differently then CVS. I figure I am looking at this and making it overly complex. It seems the only way to work on a project and commit files without it being in the production code is to do it in a branch and then merge those changes when you are ready for it to be deployed. I am assuming you could also be working on other code that should be deployed so you would have to be switching between working copies, because otherwise you are working on a branch that isn't getting mixed in with the trunk or production branch? This process seems overly complex and I was wondering if anyone could give me what you think is the best process for managing this.

• mvn deploy to AWS (ssh via distributionManagement)

  - by Dexter

  I am working on deploying the WAR file to AWS using Maven. I am planning to use 'mvn deploy' for the same which would ssh the war file to AWS. I am following http://maven.apache.org/plugins/maven-deploy-plugin/examples/deploy-ssh-external.html.

• Converted PowerBuilder to ASP.Net browsing Errors

  - by user493325

  I had a powerbuilder application which i converted to web application in the format of ASP.Net (aspx) files. after deploying and publishing the converted web application (copy it and add ASP.Net and network Service AND IUser permissions to enable users to access it) in IIS V6.0 over Windows server 2003 and The ASP.Net version is 2.0 The error messages I get when I browse default.aspx web page are as the following:- Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a tag within a "web.config" configuration file located in the root directory of the current web application. This tag should then have its "mode" attribute set to "Off". <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="Off"/> </system.web> </configuration> Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect" attribute of the application's configuration tag to point to a custom error page URL. <!-- Web.Config Configuration File --> <configuration> <system.web> <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/> </system.web> </configuration> Another error message appears on the server is:- Server Error in '/' Application. Configuration Error <roleManager enabled="true"> <membership> </roleManager> Thanks in Advance...

• Why am I getting a permission denied error on my public folder?

  - by Robin Fisher

  Hi all, This one has got me stumped. I'm deploying a Rails 3 app to Slicehost running Apache 2 and Passenger. My server is running Ruby 1.9.1 using RVM. I am receiving a permission denied error on the "public" folder in my app. My Virtual Host is setup as follows: <VirtualHost *:80> ServerName sharerplane.com ServerAlias www.sharerplane.com ServerAlias *.sharerplane.com DocumentRoot /home/robinjfisher/public_html/sharerplane.com/current/public/ <Directory "/home/robinjfisher/public_html/sharerplane.com/public/"> AllowOverride all Options -MultiViews Order allow,deny Allow from all </Directory> PassengerDefaultUser robinjfisher </VirtualHost> I've tried the following things: trailing slash on public; no trailing slash on public; PassengerUserSwitching on and off; PassengerDefaultUser set and not set; with and without the block. The public folder is owned by robinjfisher:www-data and Passenger is running as robinjfisher so I can't see why there are permission issues. Does anybody have any thoughts? Thanks Robin PS. Have disabled the site for the time being to avoid indexing so what is there currently is not the site in question.

• How to update maven local repository with newer artifacts from a remote repository?

  - by Richard

  My maven module A has a dependency on another maven module B provided by other people. When I run "mvn install" under A for the first time, maven downloads B-1.0.jar from a remote repository to my local maven repository. My module A builds fine. In the mean time, other people are deploying newer B-1.0.jar to the remote repository. When I run "mvn install" under A again, maven does not download the newer B-1.0.jar from the remote repository to my local repository. As a result, my module A build fails due to API changes in B-1.0.jar. I could manually delete B-1.0.jar from my local repository. Then maven would download the latest B-1.0.jar from the remote repository the next time when I run "mvn install". My question is how I can automatically let maven download the latest artifacts from a remote repository. I tried to set updatePolicy to "always". But that did not do the trick.

• How do I manage dependencies for automated builds on my build server?

  - by Tom Pickles

  I'm trying to implement continuous integration into our day to day workings. In our team, we're moving from just building our code in Visual Studio on our workstations and deploying, to using MSBuild.exe and automating on our build server (which is Jenkins) without the use of Visual Studio. We have external dependencies to references such as Automap in our projects. Because the automap (for example) dll isn't on the build server, the msbuild execution fails, for obvious reasons. There are other dll's which I need to be part of the build, I'm just using automap as an example. So what's the best way to get any dependencies onto the build server as part of the automated build? I've seen references to using a 'lib' folder, but I don't really understand where I should be putting it (in my project, filesystem, SVN ...?), and how the build server will get to it. I've also read that NuGet can do something with dependencies, but my build server isn't connected to the internet, and I don't understand how I can get my build to pull a NuGet package I may have created, and how it works together. Edit: I'm using subversion and we cannot use TeamCity as we would have to buy it and there's zero chance of funding.

• If the dependency is a unique snapshot version and install is called, what does maven select?

  - by chrsk

  Imagine two projects. The first is the framework-core project which is in version 1.1.0 and has several snapshot builds. The other is the example-business project which has the following dependency to framework-core on the build-iteration number 9. <dependency> <groupId>org.example</groupId> <artifactId>framework-core</artifactId> <version>1.1.0-20100518.134928-9</version> </dependency> What happens if mvn install is called on the framework-core? I found out that the artifact is copied to the folder and is named to *.1.1.0-SNAPSHOT.jar (as expected). This lead me to the assumption that this version is only used if even this 1.1.0-SNAPSHOT version is defined as dependency and not the precise build. To test something local without deploying it to the maven repository: call mvn install, change the dependency to 1.1.0-SNAPSHOT -- and the artifact just installed is used? Or is it possible to overwrite the specific build (with using the install lifecycle phase)?

• How do you prevent Git from printing 'remote:' on each line of the output of a post-recieve hook?

  I recently configured an EC2 instance with a Git deployment workflow that resembles Heroku, but I can't seem to figure out how Heroku prevents the Git post-receive hook from outputting 'remote:' on each line.

• Looking for a RESTful or SOAP pipeline between WordPress and InterWoven TeamSite

  - by deanpeters

  I've been Googling my brains out trying see if there's a simple way to bridge content to and from WordPress to and from TeamSite. I'm coming at this from the perspective of a WordPress developer. I see in the book "The Definitive Guide to Interwoven TeamSite" (http://bit.ly/d3z4wI) mention of objects for the Interwoven LiveSite product: com.interwoven.livesite.external.impl.RSS com.interwoven.livesite.external.impl.SOAP If I understand the above objects correctly, these allow me to instantiate objects of these data types, which after populating them via various method calls, allow me to render content using com.interwoven.livesite.external.ExternalCall ... but I'm not sure. Nor do I think this approach provides me the 2-way street I seek. As it stands now, from my limited understanding, it appears that the least path of resistance is deploying Interwoven's LiveSite with the existing TeamSite implementation so content can be both consumed and rendered via RSS ... an channel which WordPress can produce and consume; the latter with plugins such as wp-o-matic and/or feedpress. So the question is, does anyone out there have experience with a SOAP or RESTful API approach to InterWoven's TeamSite? If so, can I get some direction on documentation? Or is the addition of LiveSite + RSS the most feasible 2-way channel?

• What are Sharepoint(MOSS 2007) Developement/Deployment best practices.

  - by Satish

  We are deploying sharepoint MOSS 2007 at our work. I'm trying to come up with a sharepoint development and deployment methodology. We have Dev/QA/Prod environments and I need a way, preferably automated to deploy changes from Dev to QA and from there to prod. We are creating site collections web parts etc. Some of it is done directly within sharepoint, some through Sharepoint designer or visual studio. I'm looking for a way to extract this and deploy it to other enviornments. I tried stsadm backup/restore import/export etc but they all move the data along with it as well. I just need the structure deployed. Content deployment paths and jobs does the same thing as well. We use MSBuild & Curisecontrol.net for other .net projects to automate build/deployment process. I'm looking for something similar with sharepoint if possible. What are your best practices for this? Since my team is learning we don't have a defined process and we are open to change our development process if needed.

• Worklight console app, update

  - by jarkko

  We're using Worklight 6.1.0.0 / WebSphere 8.0.0.2 (ND/aix). This seemed pretty close to my question too, but for version 6.0. I've successfully done uninstall/install to our worklight console war package. However, there is some extra work on re-deploying adapters and such. I was looking for a way to just update the console. Among the ant tasks there is a target 'minimal-update', which sounds like what I'm looking for (is it?). However when all other pieces fell into place, I have an error for mapping the datasources: ADMA0007E: A validation error occurred in task Mapping resource references to resources. The Java Naming and Directory Interface (JNDI) name is not specified for resource reference jdbc/WorklightDS in module Worklight with EJB name . Contents of the 'minimal-update' task is pretty much the same as for 'install'. I tried that as update from websphere admin console (but i should use the ant task - right?), that gave me a wizard screen to map jdbc/WorklightDS from package to jdbc/WorklightDS on server. This left me wondering how could I tell this using the ant task.

• Incremental deploy from a shell script

  - by WishCow

  I have a project, where I'm forced to use ftp as a means of deploying the files to the live server. I'm developing on linux, so I hacked together a bash script that makes a backup of the ftp server's contents, deletes all the files on the ftp, and uploads all the fresh files from the mercurial repository. (and taking care of user uploaded files and folders, and making post-deploy changes, etc) It's working well, but the project is starting to get big enough to make the deployment process too long. I'd like to modify the script to look up which files have changed, and only deploy the modified files. (the backup is fine atm as it is) I'm using mercurial as a VCS, so my idea is to somehow request the changed files between two revisions from it, iterate over the changed files, and upload each modified file, and delete each removed file. I can use hg log -vr rev1:rev2, and from the output, I can carve out the changed files with grep/sed/etc. Two problems: I have heard the horror stories that parsing the output of ls leads to insanity, so my guess is that the same applies to here, if I try to parse the output of hg log, the variables will undergo word-splitting, and all kinds of transformations. hg log doesn't tell me a file is modified/added/deleted. Differentiating between modified and deleted files would be the least. So, what would be the correct way to do this? I'm using yafc as an ftp client, in case it's needed, but willing to switch.

• Deploy to web container, bundle web container or embed web container...

  - by Jason

  I am developing an application that needs to be as simple as possible to install for the end user. While the end users will likely be experience Linux users (or sales engineers), they don't really know anything about Tomcat, Jetty, etc, nor do I think they should. So I see 3 ways to deploy our applications. I should also state that this is the first app that I have had to deploy that had a web interface, so I haven't really faced this question before. First is to deploy the application into an existing web container. Since we only deploy to Suse or RedHat this seems easy enough to do. However, we're not big on the idea of multiple apps running in one web container. It makes it harder to take down just one app. The next option is to just bundle Tomcat or Jetty and have the startup/shutdown scripts launch our bundled web container. Or 3rd, embed.. This will probably provide the same user experience as the second option. I'm curious what others do when faced with this problem to make it as fool proof as possible on the end user. I've almost ruled out deploying into an existing web container as we often like to set per application resource limits and CPU affinity, which I believe would affect all apps deployed into a web container/app server and not just a specific application. Thank you.

• How to access a web service behind a NAT?

  - by jr

  We have a product we are deploying to some small businesses. It is basically a RESTful API over SSL using Tomcat. This is installed on the server in the small business and is accessed via an iPhone or other device portable device. So, the devices connecting to the server could come from any number of IP addresses. The problem comes with the installation. When we install this service, it seems to always become a problem when doing port forwarding so the outside world can gain access to tomcat. It seems most time the owner doesn't know router password, etc, etc. I am trying to research other ways we can accomplish this. I've come up with the following and would like to hear other thoughts on the topic. Setup a SSH tunnel from each client office to a central server. Basically the remote devices would connect to that central server on a port and that traffic would be tunneled back to Tomcat in the office. Seems kind of redundant to have SSH and then SSL, but really no other way to accomplish it since end-to-end I need SSL (from device to office). Not sure of performance implications here, but I know it would work. Would need to monitor the tunnel and bring it back up if it goes done, would need to handle SSH key exchanges, etc. Setup uPNP to try and configure the hole for me. Would likely work most of the time, but uPNP isn't guaranteed to be turned on. May be a good next step. Come up with some type of NAT transversal scheme. I'm just not familiar with these and uncertain of how they exactly work. We have access to a centralized server which is required for the authentication if that makes it any easier. What else should I be looking at to get this accomplished?

• RMagick transparent_color deprecated? What's the alternative?

  - by user315975

  I'm developing an app that does a fair amount of generating transparent pngs on the fly. These are used as overlays, to show areas of interest in a graphic, so they have to have transparent backgrounds. I am developing in Ruby on Rails, deploying on Heroku. What works fine in development is not working in production. I get this error when I call a drawing routine using RMagick: NotImplementedError (the `transparent_color=' method is not supported by ImageMagick 6.2.4): /usr/local/lib/ruby/gems/1.8/gems/rmagick-1.15.17/lib/RMagick.rb:1691:in `transparent_color=' I'm using RMagick version 2.12.1 on the development machine, but I'm not exactly certain how to discover the version of ImageMagick that it's running, so I'm not sure if this is a case of my local code being behind or ahead. I'm hoping behind, because perhaps then there'll be a replacement for this call. Does anyone know what the fix is here? What's required to generate a transparent background, if not the call I'm using? I can't find this in the documentation: in fact, it was on a third-party site that I found mention of this capability.

• What's the state of PHP unit testing frameworks in 2010?

  - by Pekka

  As far as I can see, PHPUnit is the only serious product in the field at the moment. It is widely used, is integrated into Continuous Integration suites like phpUnderControl, and well regarded. The thing is, I don't really like working with PHPUnit. I find it hard to set up (PEAR is the only officially supported installation method, and I hate PEAR), sometimes complicated to work with and, correct me if I'm wrong, lacking executability from a web page context (i.e. no CLI, which would really be nice when developing a web app.) The only competition to I can see is Simpletest, which looks very nice but hasn't seen a new release for almost two years, which tends to rule it out for me - Unit Testing is quite a static field, true, but as I will be deploying those tests alongside web applications, I would like to see active development on the project, at least for security updates and such. There is a SO question that pretty much confirms what I'm saying: Simple test vs PHPunit Seeing that that is almost two years old as well, though, I think it's time to ask again: Does anybody know any other serious feature-complete unit testing frameworks? Am I wrong in my criticism of PHPUnit? Is there still development going on for SimpleTest?

• Can I share code & resources between Android projects without using a library?

  - by Tom

  The standard advice for sharing code & resources between Android projects is to use a library. Personally I find this works poorly if (a) the shared code changes a lot, or (b) your computer isn't fast enough. I also don't want to get into deploying multiple APK's, which seems to be necessary when I use dependent projects (i.e. Java Build Path, Projects Tab). On the other hand, sharing a folder of source code by using the Eclipse linked source feature works great (Java Build Path, Source tab, Link Source button), but for these two issues: 1) I can't use the same technique to share resources. I can create the link to the resources parent folder but then things get wonky and the shared resources don't get compiled (I'm using ADT 21). 2) So then I settle for copying the shared resources into each project, but this doesn't work because either. The shared code can't import the copy of its resources because it doesn't know the package name of the project that uses it. The solution I've been using is to access the resources dynamically, but that has become cumbersome as the number of resources grows. So, I need a solution to either (1) or (2), or I'll have to go back to a library project. (Or maybe there is another option I haven't thought of?)
