Is there any way, compatible with computer science rules, to make at list 2 flows in one project like this:
External system 1 -> SOAP endpoint (mule) -> java object -> transformation -> java object -> SOAP endpoint (mule) -> External system 2.
Our non working solution:
single flow
We experience bug [www.mulesoft.org/jira/browse/MULE-5926]. Yes I read [stackoverflow.com/questions/25744541/mule-issue-more-than-one-jaxbcontext].
The solution which has nothing in common with the ESB philosophy but has one major single advantage, it works: looks like looks like this
Some helpful resources:
[www.enterpriseintegrationpatterns.com/patterns/messaging/] - notice please there are separate router and translator components.
Any ideas?
Best Regards, Apologies I can post only 2 links due to my reputation rank.
The reason the last image works is more about what you cannot see. Just visually seeing the Java component on the MuleSoft canvas (screen where you "draw" the flow or integration solution) doesn't provide enough detail as to what the Java component is doing. And, while the icons on the canvas are nice, we generally inspect problems by looking at the XML.
Your question is not clear. The flow that you described in your image can't be discerned into an integration pattern I recognize and the details behind your flow design are vague.
Please provide your Mule config (XML) for the same flow, but first try to edit your question to explain exactly what you are trying to do. Stackoverflow is a place where problems are identified and problems are resolved. It's also a place for the history of what we do. It is up to us to do our homework before we add new questions. Myself or maybe someone else will help you but only after you clearly explain your problem. Yes, other solutions work but there's no way I can compare your flow to the simple one with the Java component without a LOT of background information.

Background:
I noticed this interesting post on Twitter about a Java API for Karate: https://twitter.com/ptrthomas/status/1344290316212342784
I don't have a twitter account so unable to reply - hope you don't mind me asking here instead.
I have used Karate (with the parallel runner, feature files and all) in one work project and it is a joy to use - and a few folks in the workplace are very impressed with the complex JSON assertion. We are achieving a level of JSON response field coverage for that project that is not possible with other frameworks (IMO).
I've now been tasked with improving an older test project which uses JUnit + RESTAssured, but has quite limited field assertions. I am unable to fully convert it to raw Karate (too many tests, not enough time), but I'm keen to explore the possibility of supplementing what is there already with the Karate Java API mentioned in above twitter post.
For example - for an existing test which gets a Response using RESTAssured, it would be nice for me to somehow use the 'contains' method (or any of the methods in Match class) in Karate to assert that response, as it is the best JSON assertion tool I have come across.
Questions:
Off the bat - is this a practice you would recommend for my use case? Let me know if you think this is an anti-pattern. I ask this because the example here (https://github.com/ptrthomas/karate-showcase) is not using RESTAssured to get the response and my use case is a bit different.
If its worth exploring - I assume this stuff will be available in v1.0.0? (I see public methods such as that are on the develop branch, but couldn't see it on the v1.0.0 github thread).
but I'm keen to explore the possibility of supplementing what is there already with the Karate Java API mentioned in above twitter post.
That's very interesting and you have got me also thinking about this potentially interesting way to introduce Karate to legacy projects. I do get this question on how to magically migrate existing RA tests a lot.
I would recommend it. You can expect a 0.9.9.RC3 next week that should have all the assertions you want. And the API has been simplified so you don't need to call isTrue() etc.
We plan to have better examples (maybe you can help) but for now, use this as a starting point (look at the last test / very end of the file): MatchTest.java
If you want to get started now (which I recommend and you can provide more feedback) do take a look at the developer guide: https://github.com/intuit/karate/wiki/Developer-Guide
I've spent the last few days trying to understand if I should use api blueprint, RAML or swagger.
It looks like swagger has the biggest community but the closer I look the more I feel that it greatly lacks in documentation (I was forced to look at the code many times to try and integrate it with my current project), many github issues and stackoverflow questions are unanswered.
Is it possible that I am missing something here?
All I want is a tool to help me write the API documentation and test the endpoints.
Why must swagger become part of the server logic?? If I create swagger files in the editor and then serve them to the UI directly it breaks..
As far as I can tell it even makes the server slightly slower and forces the existence of many clumsily maintained integrations :p What am I missing here?
We're trying to work a lot on improving the documentation of Swagger. It's a bit more difficult when many of the projects are community-driven and not managed by a single organization.
We actually try to reply to issues on github quickly (we don't always succeed) and we have our own google group for general questions so we follow stackoverflow somewhat less.
The editor you mention is a new tool as part of the work on Swagger 2.0 and it's not final yet. As such, it still have a few bugs and missing features. The UI is also in the process of being adapted to Swagger 2.0 and the same limitations apply to it.
You most certainly don't have to integrate it with your server and you can expose the documentation statically. The advantage of integrating it with the server is that it's easier to maintain if the API changes.
You can try RAML + ramlev + Abao
The steps should be
Write API Spec in RAML with your fav editor, ie. Atom, vim
Validate your RAML with ramlev
Implement the server logic according API Spec
Validate server logic with Abao
I've been strugling with WCF to do REST the way I want it to work. And apparently so has quite a few others. I've heard about the WCF Web Api project, but wrongly dismissed it without looking too closely at it. Sadly, now that I'm looking at it I find that the documentation is rather outdated. Like, this blog post has some nice information, but classes have changed, parameters have changed, in short, design has changed.
So I've been using an old example of how to plug in Json.NET (newtonsoft) as my serializier, only to realize that after I had it working, it wouldn't work for my IErrorHandler. Further I had a problem with how to Deserialize a string from the uri template to an operation Type parameter.
It appears however that I should be able to solve these two problems (and presumably many others that I haven't stumbled over yet) by using the media formatter extension point and what's referred to as Processor<..>s in outdated documentation, which is now HttpOperationHandler<..>s unless I've missunderstood.
My problem is rather basic, I can't figure out how to correctly configure my IIS-hosted app to use my operation handler, assuming I've implemented it correctly. Since it feels rather dumb to ask for instructions on such a basic thing, I'll rather ask where I can find some documentation on how to do this sort of thing? (Explanations are welcome of course.)
I'm not after seing which classes exist, or what their methods are named with what parameters. I can see all that in my object browser. I need documentation for the overall design, and/or examples implicitly describing things like:
How do the different classes in the API fit together?
How can I configure from web.config?
Must I rather do a custom HttpServiceHostFactory?
What and how are you meant to use the framework?
How should I extend to reach what sort of goals?
How should I configure to place the extensions in effect?
From the lack of answers I assume the documentation quite simply isn't ready.
I was looking for it on the codeplex site under the Documentation tab, and found outdated stuff.
However, after familiarizing myself a bit with Codeplex I found out that the good stuff was in this Discussion section. Searching a bit in there helped a lot to be honest.
Concerning config-file configuration, I didn't find anything, so I'm assuming this will be added as the last thing before official release. Meaning I'll use the HttpConfiguration in a custom HttpServiceHostFactory for now.
The trick about the HttpOperationHandlers was twofold: Firstly I was throwing an exception in my operation and hadn't implemented a global HttpErrorHandler yet. (Doh!) Secondly I didn't know that the parameter name of HttpOperationHandler<..>.OnHandle had to match the name of the operation parameter.
Where can I find the code for creating an online rebol console like the one here ?
http://tryrebol.esperconsultancy.nl/
Update: for the sandbox system on the server, can't Rebol manage it itself with some security wrapper and its security options ?
As for console itself, I don't know Ruby so I don't want to use TryRuby and why would I need it ? Can't I mimic Rebol console itself by "remoting" it somehow ? Why RT or Esper Consultancy can't make an opensource version ? There's no value in keeping it closed source. Rebol needs to prove it's more open than in the past.
In my opinion, you should aim higher with something like the already open-sourced Try Ruby. You'd type in expressions and it would guide you. Their showcase site is at tryruby.org and is fairly slick.
I modified TryRuby to work with Rebol and it wound up looking like this:
But I'm not going to run it on my server because I didn't want to belabor the necessary sandboxing/etc. or protections against someone running an infinite loop. I can give you what I've got so far if you want it.
I started a tutorial script here that no one seemed interested in helping me with, so I wandered off to other tasks:
http://www.rebol.net/wiki/Interactive_tutorial_script
I'm not sure what exactly you want. You mention you want a remote REBOL shell instead of a tutoring setup, but that's what the Try REBOL site is. There are several reasons it's not open source:
It's in heavy development. I'm currently changing the code regularly.
So it's not in a release state. Preparing it for release, documenting and publishing it would take a lot of extra work, as with most projects.
It's written in my CMS that's also in heavy development. Even if the Try REBOL site were open source, it wouldn't run. The CMS is not planned to be open sourced soon.
It's not meant as a generic REBOL remoting tool, but as a one-off demo site. If that site is running, what's the use of more of them?
As others have answered, there are many generic solutions for remoting that you could use. Also, most parts of the Try REBOL site are readily available as open source:
Syllable Server, produced and published by us.
The Cheyenne web server.
The HTML source of the web client can be viewed, including my simple JavaScript command service bus.
Syllable Server is an essential part of the site, as the sandboxing is not done with REBOL facilities (except some extra limits in the R3 backend), but with standard Linux facilities.
A truly air tight (do I mean silica tight?) sandbox is close to impossible with R2.
R3 (still in alpha) is looking a lot more promising. The deep technical discussions in flight right now (see Cure code and AltME/REBOL3 Proposals regarding unwinds and protect and even occasionally mentioning sandboxes should lead to an excellent sandbox capability.
Right now, the big advance R3 has that makes Kaj's tryREBOL possible is R3's secure policy settings which make it possible (with some careful wrapper code) to construct an alpha/demo sandbox.
To answer your precise question("where can I find code...", you could try asking Kaj for his :)
I'm new to StackOverflow. I'm not sure if this is going to end up as a reply to your comment, or as a new answer.
The somewhat common idea that any project can be open sourced and contributed to by others is a naive view. In the case of my Try REBOL site, it makes no sense. It's not just in heavy development; it's written in a CMS that's also in heavy development. Basically noone could contribute to it at this point, because I'm the only one who knows my CMS. Or in any case its newest features, which I develop by developing Try REBOL, and other example sites. So developing Try REBOL means developing the CMS at the same time, and by definition, I'm the only one who can do that.
More generally, my projects are bleeding edge, innovative technology with a strong vision. The vision is mine, and to teach it to others, I have to build it to show how I intended it to work. So there's a catch 22: to enable others to contribute, I have to finish my projects first, because people typically don't understand them until I show them how they work.
There certainly are other projects where mass contribution makes more sense. Still, only the top projects get the contributors. We found that out the hard way. We created Syllable Desktop and Syllable Server with surrounding infrastructure for contributions. These are fairly classic, well understood operating systems that many people could work on in parallel. However, despite years of begging, we get very few contributions.
So, if you feel a burning need to contribute to our projects, please pick one of the many tasks in Syllable to execute. :-)
I've been recommended the Click framework from Apache. But I can't find any forums talking about benchmark, reviews, advantages, disavantages, usefulness, ease of implementation, etc.
I've been asked to use it to develop a web site, but I'm completly in the dark about its strengths and weaknesses.
And its damn name isn't helping !! Click ? Hey Apache ! Call your next framework "the" just for fun. I dare you.
So can anyone comment on his experience with Click ?
What I personally like about the Click framework is that it is fairly close to HTML/HTTP and the Servlet API. There is no huge abstraction to get familiar with. You have a Page class, a Form class, ... If you need to preserve state across invocations you put it in the session or you pass it through the URL... This makes it easy to start using it. It is also straightforward to control the HTML pages being generated. It may sound like it is a very basic framework but the simplicity is actually one of it greatest strengths.
Other frameworks (e.g. Seam) are more suitedr to create a very large web application with lots of reusable components and complicated pageflows but the learning curve is much steeper. So for me Click works well for small to medium sized websites.
It's an apache incubator project but that does not mean the project is not stable, rather it reflects that it is in transition to the Apache project model.
Click is Apache's version of a component based web framework equivalent to JSF (other component base Java Frameworks are Tapestry and Wicket)
