Is it possible to use corda node-explorer for cordapps other than cash? Is there any open source project to visualise what's going on in the blockchain for my cordapp?
Node Explorer currently only works for the cash CorDapp.
I don't know of any other open source projects to visualise activity on Corda.
However, it would make for a great project to extend Node Explorer to include other CorDapps, the source is available here https://github.com/corda/corda/tree/master/tools
It is a long back question, but still want to update since someone may need this.
A Beta Release for Node-Explorer was released recently, whose key highlight is:
Node Explorer is able to point to your own CorDapps.

Does Corda node explorer work with Tokens?
I am able to connect to the the stockpaydividend coradapp via Corda node explorer.
Everything seems to be working fine except the Vault Explorer.
When clicking on the vault explorer, I get the following error.
Described type with descriptor net.corda:Ilpg7fRBQWWGmwpkEi3Mtg== was expected to be of type class
com.r3.corda.lib.tokens.contracts.types.TokenType but was class com.r3.corda.lib.tokens.contracts.types.TokenPointer
Thanks
Ideally yes the node explorer doesn't really care about the data types of what's used in flows or states or anything like that.
This looks like it MIGHT be a bug so if you haven't modified the CorDapp it would be worth making an issue on github.

I created a snapshot view using Rational ClearCase explorer.
After creating it, I set the config specs, environmental variables and later tried compiling my code and got an MVFS error which says:
Unable to determine if the current working directory is in MVFS - no such device or address
When I searched the IBM website for the sake of eliminating this error, I found out that a snapshot view does not use the MVFS !
Why am I getting this error when Snapshot view does not use MVFS?
When this issue got triggered: Actually in our project we were using a ClearCase (8.0.0.7 version). We never had problems when we tried to build our code on the 8.0.0.7 version. It was only after upgrading this version to 8.0.0.15 that the build issue has arisen. The legacy of both old and new ClearCases are baseClearcase
Some more specifications regarding the issue:
The server which we are using is a Windows 2003 server. I am creating a snapshot view in H drive (NTFS drive) as C drive is not available for use in our project, cleaning the previously built files by running the shell script clean_view.sh and then compiling our C code with the ClearCase command clearmake.exe all. Previously we used to follow the same procedure where build used to succeed, but now the same has become an issue.
This question is an extension to the question which I have asked previously. I am re-posting this question as a whole thing again in order to give more clarity about the issue and also for more number of ClearCase experts to chime-in. Kindly do not treat this as a duplicate one or force close it as my issue has not yet been resolved. Also please note that this is the first time I am working with ClearCase.
LINK FOR THE PREVIOUS QUESTION: MVFS error in a snapshot view
Recently there was a development in the solution of this issue !! We escalated this issue to IBM with the help of our client. They suggested us to use Dynamic views and we used them. To our surprise it was working fine and we are able to generate the executables. But the fact still remains that we are not able to use snapshot views !!
NOTE: This comment is just to share my knowledge and experience regarding this issue. :)
While a snapshot view isn't in the MVFS, clearmake has MVFS-specific functionality for build auditing.
You mentioned that the "H" drive contained the snapshot view, is H:
A local or network drive?
A drive letter created via SUBST? In this case, is the parent drive local?
Do builds in dynamic views still work?
Does the C drive exist? Is it remapped in a Terminal Server/Citrix environment?
A caveat: Windows Server 2003 is nearly a year past MICROSOFT'S end of extended support. I would recommend updating the server environment as soon as possible.
Truthfully, issues where a process fails, and the ONLY change is the ClearCase version are usually best handled by contacting IBM instead of using this venue. Not trying to shill or anything, but if it's a clearmake bug, it has to go there anyway...
Additional questions:
If the C: drive is inaccessible on the system, which is what "can't even get the properties" in the comment seems to infer, where is the OS installed? Where does %SYSTEMROOT% point?
If it worked on a different drive, what's different between those 2 drives (H: Failed and R: worked)
I wanted to launch an instance with high availability with out having risk factor i.e, an instance will be launched in multiple regions(zones) that to sync the state like database(master-slave). When some applications got installed, same should reflect in another region/zone also(mostly image format). Can we do that?.
I have checked some links based on this. I got a confusion after reading all the docs.

Exactly what is the difference among. VM replication & syncing is possiblein Openstack?
To the best of my knowledge, Open Stack does not support VM replication for now.
There is a component called Remus under the Xen project, which could potentially used by manual configuration as Open Stack supports Xen (https://www.xenproject.org/directory/directory/projects/70-remus.html). But it seems to be slow and unstable.
The newest approach is called reversed virtual machine replication (http://dl.acm.org/citation.cfm?id=2996894&CFID=918229768&CFTOKEN=85577813), this one seems to be very interesting and some critical problems in VM replication is well defined and elegantly solved. However, I did not find the open source project for it.
We use artifactory as a repo manager. We store packages for releases in repo libs-release-local and snapshot packages in libs-snapshot-local.
For example: If we send the war (web app) into test, it should be from libs-snapshot-local and if it is into stage & prod it will be from libs-release-local.
I will say a scenario, where I needed help below:
Once the war is certified good on test server we would send the same code to stage.
We saw a bug after deployed into stage, so we changed the code and again build it, it obviously cannot go to same versioned release(as in artifactory, we cannot override releases).
So,
What will happen if we recognized 10 bug fixes one at a time, after each deployment in stage ?
What if we have realized there are bug fixes after going to prod.
Artifactory will have bulk of folders with so many version names & folders. Is that good practice? Or else anything senses wrong in our procedure?
Thanks!
Suggest to read Binary repository management Refcard first.
You need define your strategy for your folders and wars (web application), it is already good to use different repo for different purpose (snapshot/release)
The process for maintenance is simple
fix the bug and increase the version, send to the libs-snapshot-local for testing
after testing, a.k.a QA passed, the packages are promoted to release/stage repo libs-release-local again for public use again.
In this case, bug fix is the same as normal development procedure.
or you can refine the questions to make your questions more clear.
i am working in Selennium Webdriver2 with IE specific application. i know we can take the screenshots of the execution. similarly, Is there any option to record selenium execution as a video?
There is nothing in WebDriver.
Sauce uses http://www.ffmpeg.org/ to record video's. There are other options like https://code.google.com/p/java-remote-control/.
Generally the answer is that if you want to do it, you are going to have to implement it yourself.
This API helped me in solving the above problem, this is for your reference guys,
Selenium provides us with the feature to run the automation code/suite and record the output as a video and save it on your system. This video can then be shared with anyone who can see what the automation is doing. First of all, to enable video recording, we need to download some important jars. They are freely available to download from Google. Below are the jars to be downloaded. These are the latest version available, any other version can also be downloaded:
ATUReporter_Selenium_testNG_5.1.1 and ATUTestRecorder_2.1
