I want to know if there are anyways to automate datapower deployment. I have seen DpAdmin and DPBuddy are available in the market, but is there anyway we can do it ourselves writing some ant scripts and integrating with Jenkins
Yes of course. There is a web service API that you can access most of the features. It's called "SOMA".
An old, but rather good eBook.

More stuff on it here: http://www.ibm.com/developerworks/websphere/library/techarticles/1308_tuli3/1308_tuli3.html
You can setup anything that does HTTPS/POST and send scripted xml files containing the SOAP envelope if you do not wish to make a complete SOAP client.

I want to share the pact file from consumer to bitbucket and then provider can use from the same location.
Does anybody implemented this?
Thanks in advance.
It's worth noting that it's very much a non-standard way of doing it and I would highly recommend you don't do it this way (see https://docs.pact.io/pact_nirvana/step_4/). You're going to have to build a lot of the workflows again, and that will require investment in building tooling and coming up with ideas to evolve the contract. At some point, you'll be rebuilding key features the Pact Broker already has and would be better off just running that or using a hosted service like pactflow.io.
So, without a pact broker, you don't get the can-i-deploy tool, versioning, environment management and all of these powerful workflows.
With that said - if you do want to use bitbucket:
you'll need to create a manual process (i.e. script) to upload (from consumer) and download (provider) from bitbucket
You'll only want to upload from CI, so that's easier to control
For provider verification, you really want to do this on a laptop, so you'll need a standard approach for pulling down the correct contract to verify there and on CI. Every team member will need credentials to read from that repo
Pact doesn't have a mechanism to pull from git protocols, but you could potentially add that feature to the languages you need them for
I have developed an ExtJS 5 + .NET MVC WebAPI RIA for reporting purposes.
Now the client is requesting a feature to subscribe to some reports. The reports (pdf) should be generated automatically and then the server should send them per mail to the user who subscribed a report. It would also be a nice to have that the user can specify the date and time when he will receive the report.
Currently the application has already a PDF export where the user can save these reports. In this case the applications sends the html of the report section to the server and the server is working with wkhtmltopdf to generate the pdf.
For my new feature i have the following questions:
Can i implement this new feature service in my WebAPI (e.g. as a thread which ill start on startup) or should i write an independet service for it.
Would it be appropriate to just load the site on the server with the reports and execute the process which i am already running for my PDF export to get the pdf out of it?
I am thankful for every advice.
A separate process that calls the WebApi makes a lot of sense. Separation of concerns and all that. But whether you include it in the API itself or in a separate mailer portal, I suggest you don't try to write any scheduling yourself. Scott Hanselman has a great post on why you shouldn't and suggests several alternatives. Of those, my favorite solution is Hangfire. I use it in production, and it's pretty easy to set up and use.
And if you need nicely formatted emails, I suggest checking out Postal for their composition.
can any one explain java callout a little help will do.Actually i am having several doubts regarding where to add the expressions and message flow jar and where to add my custom jar.
Can i access the resources/java folder directly and can i use it to store my data?
First, check the docs on apigee at
Customize an API using Java
http://apigee.com/docs/api-services/content/customize-api-using-java
Keep in mind Java Callouts are only supported in the paid, Apigee Edge product, not the free Developer platform.
As you decide how to use Java, you should consider this basic hierarchy of policy management:
Policy Configuration First: Apigee policy configurations are in broad use and therefore tested daily by clients and most performant.
Javascript Callout: For stuff you can't do in a standard policy there is Javascript -- keep in mind this is "Compiled Javascript" which means at the time you deploy your project the JS gets interpreted by the Java Rhino engine and then runs like native code. Very fast, very scalable, and very easy to manage as your code is all in plain text files.
Java: You have to have a pretty compelling reason to use Java. Most common cases are where you have some complex connection that needs to be negotiated with custom encryption schemas or manipulating binary content. While perfomant, it's the most difficult code to manage (you upload compiled jars, so if someone takes over your work, the source code is in a separate place than your deployment bundle), and it's the most difficult to debug in the event of a failure.
To your specific question: All Apigee variables are available in Java and Java gives you pretty much god-like powers on the local server where the code is executed. Keep in mind, Apigee's physical architecture is distributed -- your jar may run on different servers for different API calls, so any persistent data (that you might want to store locally) should really be put into Key Value Map and read as needed. Keep your API development as stateless as possible.
Hope that helps.
I am creating basic .NET webpages as a UI, to invoke WCF service and display the result. I feel many web developers must have come across this situation, earlier.
Is there any existing tool out there, which could take WSDL as input and generate input fields either in HTML or .NET webpages.
There is also a tool named storm that I read about but I don't have direct experience with.
http://storm.codeplex.com/
Testing a service from a web page is definetely a bad practice.
Depending of your service, there are many tools available like WcfTestClient, soapUI, WCFStorm, ... but is also a bad usage.
From my point of view, you will never find any better tool than your favorite unit test framework. The test client, nor soapUI will create a test that can run in a Continuous Integration scenario.
Let me start off by stating that I am a novice developer, so please excuse the elementary nature of my question(s).
I am currently working on a Flex Application, and am getting more and more confused about when to use server side scripting, and when to develop web services. For most of the functionality I am working on, I am taking various files from the user (client), uploading to the server for processing/conversion, then sending back to client in new format.
I am accomplishing most of this using asp.net generic handlers (ashx) files, but not very confident this is best practice. But at the same time, does making web services make any more sense? What would be considered best practice for this? Any suggestions would be greatly appreciated.
The way I look at it is as follows:
Web Services mean Established Best Practice.
For most of our development, we don't need to create "Web Services", or what I'm thinking when I think REST, SOAP, and the Twitter API. You only need to start doing that once you've got something you're going to be using every day for years.
Clean and DRY code will Lead you to Creating a Web Service
If you spend the time to clearly define the parts of your upload-process-render Architecture, and you find that it can be applied to almost everything you are doing, then all you need to do to make it a Web Service is define a clear, 1-2-3 set of rules for using the system (GET/POST data, etc.). As long as you are consciously building an architecture the whole way, you'll end up creating a Web Service if it's worthy. Otherwise there's no need.
It sounds like you have a clear workflow going, I don't know anything about asp.net though.
As far as it being confusing sometimes, and best practices, I suggest the following:
Create a Flex Library Project for your "generic ashx file handling" Flex classes. Give it a cool, simple name.
Create a .NET Library Project that encapsulates all the logic for your server-side file processing. Host it online and make it open source. I recommend github. Test it as you go, and document it, its purpose and the theory behind it.
If you don't have to do anymore work at this point, and it's just plug and chug, then you've probably arrived at something that might become a Web Service, though that's probably a few years down the road.
I don't think you should try to create a Web Service right off the bat. Just make some clean and reusable code, make a few examples, get it online and open source, have others contribute and give feedback, and if it solves a specific problem, then make it a web service. You can just use REST for now probably, and build your system around that. RestfulX is a great library for that.
Best,
Lance
making web services without any sense make no sense ;)
Now in the world of FLEX as3 with flash version 10, you can easily read local files, modify them with whatever modifcation algorithm and save local files without pinging server.
You only have to use webservices if you want to get some server data or to send some data to server. that's all.

Flash / Flex uses a simple HTTP POST approach for file uploads, so trying to do that using SOAP web services will be problematic. Your approach of using ASHX here sounds reasonable to me.
To send / receive data that isn't file based (e.g. a list of files the user has uploaded previously), I would recommend looking at the open source Fluorine FX library. Fluorine uses AMF which is a highly performant way of doing data transfer with Flash. It's also purely configuration-based, which means you don't need to code against any of its APIs, just configure Fluorine to expose your .NET service classes. You could easily add attributes to those same classes to expose them as SOAP web services via WCF if you need that in the future. I would not recommend using SOAP with Flex however, due to the performance losses and also because the Flex implementation of SOAP has a history of bugs and interoperability problems.
