I have a problem with CKAN 2.0, just installed on a VirtualBox VM Ubuntu 12.04 64Bit.
I followed all steps of the official documentation but when I upload a file CSV into a dataset, the preview don't work because dataviewer use Dataproxy in place of Datastore.
My question is: CKAN 2.x uses only the dataproxy for prevew csv/xls files or I can use the datastore as in the previous versions? Reading here http://docs.ckan.org/en/ckan-2.0/data-viewer.html?highlight=datastore#viewing-structured-data-the-data-explorer is not clear if Datastore is used for all type of file or for all type except CSV/XLS.
Thank you! ;)
If you have the DataStore enabled and the data for that resource (data file) stored in the datastore then the datastore rather than the dataproxy will be used for the preview.
Think of the dataproxy as a fallback that kicks in if the DataStore is not enabled (or you have not stored that data file in the datastore).

I'm running jira in openshift using the basic image from atlassian: https://hub.docker.com/r/atlassian/jira-software
So far most things work fine.
I installed a plugin using the web ui which worked as well.
But now I'm running into an issue when a pod is restarted. The pod uses the image and naturally (as specified) my plugin is not installed anymore. I can install the plugin via webservice calls and register it as an osgi module for jira. But I don't want to do this manually. Building a pipeline or jon for this is quite easy (I'm thinking jenkins or ansible tower). But I so far I didn't find a way to trigger this pipeline after the pod is started (or better after jira is started).
Anyone got an idea how to handle this?
Thanks and best regards. Sebastian
Why not create a custom image based on the Atlassian image with everything you need installed?
As far as I know, there isn't a way to trigger a pipeline when a Pod is started; only Webhook, Image Change, and Config Change triggers are available. You'll need to write a Jenkinsfile to script all of the installation and setup you want, but then that can be triggered in one of the three ways mentioned.
I'm thinking an Image Change trigger would work best for you, so when the latest version of Atlassian's image comes out, you can run your pipeline to set everything up on the latest version.
Also, just curious, but do you have some persistent storage attached to the Jira pod? If not, you'll lose everything in Jira if the Pod dies; that means tickets, boards, comments, everything.
Update:
Looking at this page, it looks like most of the stuff you're trying to persist is stored in jira-home, so maybe mounting that as a persistent volume will be a good solution for you.
You're correct that the tickets are stored in the database, but I'm guessing the database connection settings are getting wiped when the Pod is cycled.
The jira-home directory stores your application and database connection settings, as well as a subdirectory for your plugins.
dbconfig.xml
This file (located at the root of your JIRA home directory) defines
all details for JIRA's database connection. This file is typically
created by running the JIRA setup wizard on new installations of JIRA
or by configuring a database connection using the JIRA configuration
tool.
You can also create your own dbconfig.xml file. This is useful if you
need to specify additional parameters for your specific database
configuration, which are not generated by the setup wizard or JIRA
configuration tool. For more information, refer to the 'manual'
connection instructions of the appropriate database configuration
guide in Connecting JIRA to a database.
jira-config.properties
This file (also located at the root of your JIRA home directory)
stores custom values for most of JIRA's advanced configuration
settings. Properties defined in this file override the default values
defined in the jpm.xml file (located in your JIRA application
installation directory). See Advanced JIRA configuration for more
information.
In new JIRA installations, this file may not initially exist and if
so, will need to be created manually. See Making changes to the
jira-config.properties file for more information. This file is
typically present in JIRA installations upgraded from version 4.3 or
earlier, whose advanced configuration options had been customized
(from their default values).
plugins/
This is the directory where plugins built on Atlassian's Plugin
Framework 2 (i.e. 'Plugins 2' plugins) are stored. If you are
installing a new 'Plugins 2' plugin, you will need to deploy it into
this directory under the installed-plugins sub-directory.
'Plugins 1' plugins should be stored in the JIRA application
installation directory.
This directory is created on JIRA startup, if it does not exist
already.
I am new to cloud foundry. I am currently working on a requirement where I have to upload a CSV file (via JSP UI) into a service deployed in cloud foundry and persists its data in service.
The issue is from UI, I only get a local path of that CSV file and when I am trying to parse that CSV via this path the file is not recognized. I guess the reason is service is already deployed in CF, so it does not recognize this local machine path.
Can you please let me know how can I parse this CSV file in local machine and where to parse this CSV.
Thanks in Advance!
There is nothing specific to Cloud Foundry about how you would receive an uploaded file in a web application. Since you mentioned using Java, I would suggest checking out this post.
How to upload files to server using JSP/Servlet?
The only thing you need to keep in mind that's specific to Cloud Foundry is that the filesystem in Cloud Foundry is ephemeral. It behaves like a normal filesystem and you can write files to it, however, the lifetime of the filesystem is equal to the lifetime of your application instance. That means restarts, restages or anything else that would cause the application container to be recreated will destroy the file system.
In short, you can use the file system for caching or temporary files but anything that you want to retain should be stored elsewhere.

i come from web development where apps can have multiple config files for storing things like db connection strings, remote server endpoints, passwords and so on
so you have files like base.config, development.config, production.config, local.config and so on
according to the environment the app is running in the correct config file is loaded
is there any such system for Windows Phone and Windows Store apps?
if so, how can i define different configs for diffrent runtimes such as debug and production?
i would really like to avoid storing runtime config in code and then using crazy ifs
There isn't a built-in system for this, but it's pretty easy to mock up. Create and read a file with your config information then create different files for the different configurations. Create a pre-build step which copies the appropriate file for the desired configuration.
I'd probably name the files all the same but put them in different directories named for the $(Configuration) then copy from the $(Configuration) dir in my pre-build.
See Pre-build Event/Post-build Event Command Line Dialog Box on MSDN
There isn't an easy way to switch this at runtime since you can't write to the appx package after it's signed and deployed.
Just signed to the free Google cloud account (300$ Credit) to see if it supports exporting VMs in OVF format.
Created a new project and By clicking on the Compute>Compute engine> VM Instance I see below error message:
"The project you requested is unavailable."
There is no extra information provided on the screen.
Google compute engine currently doesn't support exporting VMs in OVF or OVA format. You can use free tools, e.g. VirtulBox to convert GCE images from the RAW format to VMD, VDI, VHD
https://www.virtualbox.org/manual/ch08.html#idp58756992
Here are instructions of how to create a RAW file from an image:
https://cloud.google.com/compute/docs/images#exporting_an_image_to_google_cloud_storage
In order to troubleshoot your GCE "The project you requested is unavailable" issue in developer console, you can login using Incognito window in chrome or use another browser to see if that resolves the issue.
Update: GCE supports OVA and OVF now. Here is how you can import the image.
how to load the mysql server in android emulator
i.e
Class.forName("com.mysql.jdbc.Driver")
i got the exception java.land.ClassNotFoundException in com.mysql.jdbc.Drive
please reply me.
This assumes MySQL is publicly available from internet, but it is never good idea .
Setup public WebService and connect to it from mobile application.
You won't be able to run MySQL server on an Android device.
What you're doing, however, is trying to load the MySQL client library. That isn't included as part of Android so you cannot load it. You'd need to include the relevant JARs in your project, if you really do want to connect to a remote MySQL database from an Android app.
If you do want to store and access data on your Android device, the awesome SQLite database is included by default, including all the APIs you need to create, upgrade and otherwise interact with SQLite databases.
When I did this I created PHP files for the database operations. I sent data in XML and received data in XML all using PHP scripts. I found this to be the easiest way for me...but you need to know PHP of course.
