I have a requirement where in i have to develop components using Camel. I know how to do this in pure Java. But i want to utilize Camel, wherever it is applicable. So here is a my requirement
1) Web service method
2) Validate the request data
3) Insert data into DB
4) Export data into CSV File
5) Move the CSV into a FTP location
6) Call a Stored procedure (which takes a INPUT parameter from Request)
7) Call one more Stored procedure (which takes a INPUT parameter from Request)
8) Call a Web Service and I want this Web Service to run within certain time. If it takes more than that, throw out Time out exception.
Can we achieve this using Camel. I just want to know, whether we can do it or not. If you feel it is achievable, can you show me the right direction. Help appreciated.
These are various basic tasks Camel is built to help you with.
Since Camel is well documented by both reference material and examples you can very easily find documentation online. Try it out and come back for detailed and specific questions. See some starting pages for your various tasks.

I have a gatling test for an application that will answer a survey and upon answering this survey, the application will identify possible answers that may pose a risk and create what we call riskareas. These riskareas are normally created in the background as soon as the survey answering is finished. My question is I have a gatling test with ten users who will go and answer the survey and logout, I used recorder to record the test; now after these ten users are finished I do not see any riskareas being created in the application. Am I missing something--should the survey be really answered by gatling (like it does in selenium) user or is it just the urls that the gatling test will touch ?
I am new to gatling please help.
Gatling should be indistinguishable from a user in a web browser (or Selenium) as far as the server is concerned, so the end result should be exactly the same as if you'd gone through the process yourself. However, writing a Gatling script is a little more work than writing a Selenium script.
For performance reasons, Gatling operates at a lower level than Selenium. Gatling works with the actual data that is sent and received from the server (i.e, the actual GETs and POSTs sent to the server), rather than with user-level interactions (such as clicking links and filling forms).
The recorder will generally produce a relaitvely "dumb" script. It records the exact data that was sent to the server, and makes no attempt to account for things that may change from run to run. For example, the web application you are testing might have hidden form fields that contain session information, or the link addresses might contain a unique identifier or a session id.
This means that your script may not be doing what you think it's doing.
To debug the script, the first thing to do is to add checks on each of the requests, to validate that you are getting the response you expect (for example, check that when you submit page 1 of the survey, you are taken to page 2 - check for something that you'd only expect to find on page 2, like a specific question).
Once you know which requests are failing, look at what data was sent with the request, and try to figure out where it came from. You will probably find that there are session ids, view state, or similar, that must be extracted from the previous page.
It will help to enable request and response logging, as per the documentation.
To simplify testing of web apps, we wrote some helper functions to allow tests to be written in a more Selenium-like way. Once you understand what your application is doing, you may find that it simplifies scripting for you too. However, understanding why your current script doesn't work the way you expect should be your first step.
I'm currently looking at building a lightweight integration between PivotalTracker and Salesforce.com. Reviewing this bit of PT documentation, it looks like I can do an update of Salesforce data based on PT activity. Awesome! I can't figure out how to access the XML data that is being posted however.
I can't see anything in ApexPages.CurrentPage() that looks like it will let me get to the XML. Has anyone done anything like this, without the use of an intermediate server?
I think we chatted about this over Twitter last week.
AFAIK there is (somewhat annoyingly) no way to access raw (i.e. not form posted key/values) POST data via SFDC. The Apex REST service support would be the closest thing, but requires authentication and still may not do exactly what you want.
Fairly certain you'll need some sort of middle-man proxy that simply takes the XML data and posts it to VF as a form-encoded key/value pair. That is a fairly trivial thing to do, but it's an unnecessary additional moving part and will require some sort of server resource.
I would probably first investigate if PT supports any other ping mechanism, or a way to write a custom extension to convert the raw POST into a form POST.
I need to create some automated method for checking certain security settings within a given Salesforce org(s). The four big ones are:
IP Restrictions within each profile
Mobile User setting disabled
Mobile Lite disabled
Chatter Disabled
I think the first two can be accomplished through the API (SOQL to get all profiles and check loginIpRanges[] length >0 and SOQL to get all users and check isMobileUser property for each one), but I can't find anything in the API for the other two and wonder if I would have to screen scrape it.
Any suggestions on the best approach to accomplish this? A local Python or other script that connects remotely via the API and a screen scraper or Selenium script for the non-API items? An Apex or VisualForce page that is installed within each org?
I am new to Salesforce and Apex, so before I start down one road and doing it within Salesforce vs via the API I would really appreciate any guidance.
Thank you!
I think you'll have to take a mixed approach to solving this, perhaps wrapped up in some larger python script.
Use the metadata API to get all of the Profile objects and parse for loginIPRanges. You can use Apache ANT and the Force.com migration tool commands to do this. You can also get the SecuritySettings from the same API and method and get a lot of the things in the Security Health Check, if you need them. The results will be returned in XML, which you can easily parse in your python script.
Use the API and a SOQL query to check for the isMobileUser permission, use python to parse/output results. Beatbox is a good library for connecting to the standard API.
For the last two, I think you'll need to go with some screen scraping/browser automation and parsing. Hopefully someone has a better answer for this, as I'm not familiar enough to help with how to accomplish this aspect. The screens are in standard locations so it should be repeatable as long as future updates don't move things.
Ideally you'll be able to combine these into one large script that fires off beatbox, then fires off ant/migration tool, and some browser automation script.
I'm stumped and need some ideas on how to do this or even whether it can be done at all.
I have a client who would like to build a website tailored to English-speaking travelers in a specific country (Thailand, in this case). The different modes of transportation (bus & train) have good web sites for providing their respective information. And both are very static in terms of the data they present (the schedules rarely change). Here's one of the sites I would need to get info from: train schedules The client wants to provide users the ability to search for a beginning and end location and determine, using the external website's information, how they can best get there, being provided a route with schedule times for the different modes of chosen transport.
Now, in my limited experience, I would think the way to do that would be to retrieve the original schedule info from the external site's server (via API or some other means) and retain the info in a database, which can be queried as needed. Our first thought was to contact the respective authorities to determine how/if this can be done, but this has proven to be problematic due to the language barrier, mainly.
My client suggested what is basically "screen scraping", but that sounds like it would be complicated at best, downloading the web page(s) and filtering through the HTML for relevant/necessary data to put into the database. My worry is that the info on these mainly static sites is so static, that the data isn't even kept in a database to build the page and the web page itself is updated (hard-coded) when something changes.
I could really use some help and suggestions here. Thanks!
Screen scraping is always problematic IMO as you are at the mercy of the person who wrote the page. If the content is static, then I think it would be easier to copy the data manually to your database. If you wanted to keep up to date with changes, you could then snapshot the page when you transcribe the info and run a job to periodically check whether the page has changed from the snapshot. When it does, it sends an email for you to update it.
The above method could also be used in conjunction with some sort of screen scaper which could fall back to a manual process if the page changes too drastically.
Ultimately, it is a case of how much effort (cost) is your client willing to bear for accuracy
I have done this for the following site: http://www.buscatchers.com/ so it's definitely more than doable! A key feature of a web scraping solution for travel sites is that it must send you emails if anything went wrong during the scraping process. On the site, I use a two day window so that I have two days to fix the code if the design changes. Only once or twice have I had to change my code, and it's very easy to do.
As for some examples. There is some simplified source code here: http://www.buscatchers.com/about/guide. The full source code for the project is here: https://github.com/nicodjimenez/bus_catchers. This should give you some ideas on how to get started.
I can tell that the data is dynamic, it's to well structured. It's not hard for someone who is familiar with xpath to scrape this site.
How would one create a REST web service to write a row into a databse table. Use the follwoing scenario:
The table is called Customer - the
data to be inserted into the row would
be the name, addresss, telephone
number, email.
I think its impossible to describe the whole thing end to end in Java or C#, and I would never expect that, but here are the questions I have popping into my head as I prepare for coding:
How the URI would look (eg. if you use this URL - http://www.example.com/)?
What info would go into the HTTP envelope?
Would I use POST when writing to the database in this way?
Do I use a resource to store the posted data from the client? Is this even necessary if the data is being written to a database anyway?
When the data to be writeen into the db is recieved by the server - how do I physically insert it into the database - do I call some method on the server to actually write the data (in Java)? - this doesn't seem to fit with truely REST architecture - shunning RPC calls.
Should I even be bothering writing to a DB - should I be storing my data as a resource?
As you can see I need a few issues clearing in my head. Any help much appreciated.
First of all, I'm not either java nor c# expert and I don't exactly know what means do these languages have to support REST design, but in general:
http://www.example.com/customers - customers is a collection of resources and you want to add a new resource to this collection
It depends on various things - you should probably set the content-type header (according to the data format in which you are sending the representation) and set some authentication headers if you need it.
Yes, you always use POST to create a new entry in a collection of resources.
I don't fully understand this question, to be honest. What do you mean by "inmediately writing data into the database"?
REST is primarily just a style of communication between server and a client. It doesn't say anything about how you should handle the data received by using it. The usual way how modern web approaches (MVC style frameworks) solve it, is by routing every REST action to a method of some class (usually a controller instance) where you handle the received parameters (eg. save them to the database) and generate a response to be sent back.
For a very brief and very clear introduction to REST have a look at this short video.
RESTful Web Services, published by O'Reilly and Associates, seems to fit the bill you're looking for.
As far as doing it in Java, Sun has a page on it.
