Newcomer to Alfresco and Web Development here, so bear with me. I've so far installed Alfresco and was able to use the Maven AMP archetype to create my own custom content model for the data I need to store in it. Now I need to access this data from an external site by querying the Alfresco repository.
I've followed what I can find on CMIS and was able to execute a query using curl and get the results I expect in a large XML stream. My colleague was having an uphill battle trying to interpret these results using Coldfusion. Now I searched around, and understand that to interpret these results and make the process a bit easier, it is better to use some kind of client like Open CMIS (or Chemistry, I'm still a bit confused on the terminology here).
We've so far tried the the PHP client, but received some errors from the xmlLoad function not reading 'nbsp' characters. PHP seemed like the easiest version to implement, though we're considering moving to Java if that works better. However, we've seen very scarce documentation on either end. Are there some better examples that we may have missed or maybe some other way to do this? Seems like this should be simple to implement, yet it's given us quite the stall due to the brick wall that Alfresco and CMIS seem to be.
If you don't want to use a library, the CMIS Browser Binding might work better for you. It returns JSON instead of XML.
Try:
http://<host>/alfresco/api/-default-/public/cmis/versions/1.1/browser?cmisselector=query&succinct=true&q=SELECT * FROM cmis:document
Shouldn't be a brick wall at all. Here are some resources:
The custom content types tutorial has a section on CMIS,
including CMIS queries which may be helpful to you even if you do not need custom types
The CMIS & Apache Chemistry book from
Manning is a good resource (disclosure: Florian and I co-authored it
along with another colleague, Jay Brown)
There are some Java examples on Google Code
There are additional resources and helpful links on the Alfresco CMIS page
I'm writing a web app in Scala using the Play framework. I'd like to be able to push some binary data to my web server from another machine I'm using to do number crunching. I'd like to do this over http. Can anyone suggest the best way to do each side? Ideas that have occurred to me so far are:
Send the data up as a file upload via the usual play form processing. Nice on the (web) server side, but I'm not sure what libraries to use for pushing the data up from the (number crunching) client. In C/C++ I'd consider using Curl.
Send the data up as raw POST with the binary attached and encoded appropriately. Not sure how to do either side.
I've done each of the above on several occasions in Python and C++ (although not recently enough to remember how!), but am not a web dev (but a more general sw engineer) and have only ever had control of one side before - so have no idea what the best way to do this is.
Any thoughts appreciated.

It depends what platform (and language) you're already using for the number-crunching client part. If that 'client' is also using the Play framework (or at least has access to the libraries), then there are some very helpful tools for accessing web services; (see here also).
I'm trying to (HTTP) upload a binary file programmatically from within VBA. I intend to put an ASPX page on the server to accept the file and certain additional parameters.
I know there are lots of nice ways to do that (e.g. use web service instead of aspx), but my constraint is that it must run in VBA (in an excel file), and that I cannot install any additional components on the client.
So I guess I'll use WinHTTP, and I've found several examples to post form data, but not to post a binary file. I probably need to base64 the file contents?
So my questions are:
Do I need to do the encoding manually or can I make WinHTTP do that?
Is there a better utility to use than WinHTTP? (Remember I don't want to install any additional software, it must be shipped with WinXP Pro, Office 2007 or a .NET framework, e.g.)
Is there a better way to go, e.g. using ASP.NET web services?
Thx, chiccodoro
You may use base64 but typically writing binary is easier.
The hurdle you have to leap is constructing a valid multi-par/form POST. This is completely possible using WinHTTP, although I have not done it in years and am not tooled to provide sample code, it is not trivial.
You can reference the following articles for examples of how to do this with C# HttpWebRequest. The WinHTTP api is a bit different of course but the salient points to take away from the articles is the structure of the POST body.
C# File Upload with form fields, cookies and headers (by yours truly)
UploadFileEx: C#'s WebClient.UploadFile with more functionality (a bit more procedural and may be easier to suss out the format)
Typically I provide sample code, but as I said, I do not have any stone-age tools set up right now ;-).
HTH
I'm in a project that loads a lot of XML from web services and I need to send the correct one and get the one I am expecting, a part that run the web app in Debug mode and add a breakpoint after getting the XML String, what can I have as a free plugin or even a trial program to let me see what XML is sending by my web application and what XML is been received by it?
Hope that I make sense.
I'm not sure what protocols you are using but Wireshark should show you for free :-)
Wireshark's most powerful feature is
its vast array of display filters
(over 80000 as of version 1.0.5). They
let you drill drill down to the exact
traffic you want to see and are the
basis of many of Wireshark's other
features, such as the coloring rules.

So Google Analytics does not have an API that we can use to get our data, so is there an efficient way to programaticly fetch the data collected by Google, without logging it locally?
Edit:
I would prefer a Python or PHP solution but anything will work.
Google just announced that they're making available a data export API for Google Analytics. It sounds like that's exactly what you're looking for.
Per their announcement, the feature's currently in private beta, but I figure it'll be rolled out to all accounts in coming weeks/months. Depending on your needs, you may just want to wait, instead of building a short-term hackish solution.
If you're interested, I presume that the functionality's being rolled out first to members of the Google Analytics Trusted Tester program.
Also, I forgot about this: I never actually completely implemented this for a client because the deal fell through...
But you can customize the dashboard to include the sections of Google Analytics that your report might need and have a scheduled email. If the reports do not need to be too detailed and if Google already aggregates the data in the way you need it, then this might work for you.
The Google Analytics API is now open to everyone and looks like it contains the full data set
Well, it depends on what you want to do with the data. If you only want to process part of it, then I don't think it is difficult.
Here's a basic web search with a hit explanations from Google and someone else:

There is a completely programmatic way to access the data using greqo(PHP), but the analytics class is in beta. Check it out here.
If beta is not acceptable, you can use a mixture of the XML and Yahoo Pipes to get what you need.
Basic Method
Obtain the tracking data in a usable
format – We can schedule Google
Analytics to email this as an XML file
on a regular basis.
Make the XML file accessible online –
By emailing an attachment to Google
Groups, the file is automatically
given a public URL.
Work out the URL of the most recent
report – Since Google Groups provides
RSS/Atom feeds for all messages, we
can easily find the URL of the most
recent message and therefore work out
the URL of the XML report.
Prepare the data for use – We need to
manipulate the XML and massage it into
a handy JSON format that we can use on
our blog, which can all be done using
Yahoo Pipes.
Taken from here.
I implemented a solution where we scheduled the analytics report to be emailed to a gmail account each day and I pulled the report on demand via POP3. It's pretty easy and works fast. I've heard Epic1 will do this for you as well. I'm researching that now.
If you're using Python, Pandas io is also very helpful. Pandas has an interface on top of the Google Analytics API. It's pretty simple to get up and running and integrates with Pandas so you get the aggregation, time series features, and other data analysis library features.

Its been a while since I had to deal with this, but Google Analytics has an XML output type, so you can parse that to get the data in your own system. However, I believe that there is no way to get the xml file programatically, so someone still has to go in and generate the file and feed it to your app.
Good question though, I'd love to see if there is a 100% automated solution.
We just released a product - Megalytic - that makes it very easy to create custom reports using data from the Google Analytics API. You can email these reports to others without sharing your Google Analytics account. Also, create links to reports, download as PDF, etc.
