Which version of cloverETL is needed to invoke webservices? I was looking at the site http://www.cloveretl.com/ and got confused with so many product variations.
how does it compare to oracle ODI ?
WebServiceClient component ( http://doc.cloveretl.com/documentation/UserGuide/index.jsp?topic=/com.cloveretl.gui.docs/docs/webserviceclient.html ) is available in commercial distribution of:
CloverETL Designer
CloverETL Server
CloverETL Cluster
It of course available also in evaluation versions of products above. WebServiceClient is great and simple to use tool for accessing web services, allowing simple request generating and response handling.
In community edition version is available also component HTTPConnector ( http://doc.cloveretl.com/documentation/UserGuide/index.jsp?topic=/com.cloveretl.gui.docs/docs/httpconnector.html ) which can be used for the same purpose. But you need to prepare request and process response by your own.

Our company is in the process of creating an ASP.NET service to accept XML data sent from ERP systems such as Oracle. We have no experience (at all) with Oracle, so please excuse the simplicity of this question.
I see online that Oracle has a tool called JDeveloper that can hook up to WCF Services that use a DataContract/WSDL to send/receive data with relative ease.
Can anyone advise about the situation regarding WebAPI's, where no WSDL or DataContracts exist? Is it simple to craft a POST in Oracle to send to a WebAPI, or is the former option better/easier to work with?
Thanks in advance.
It's simple enough to call web service directly from Oracle:
There are a good support of XML/XSLT/XQuery to construct requests and parse responses (XML DB)
Oracle have an API to work with HTTP/HTTPS requests (UTL_HTTP package).
So if you decide to call web service from Oracle - it's possible and relatively simple for SOAP and REST web-services.
You can find example code in this answer on StackOverflow.
Update - answer on a comment
To make it clear, example above isn't work at a "database query level" because it's implemented on PL/SQL. Oracle Database engine natively incorporates support for two different languages:
traditional SQL, which is ANSI SQL standards implementation (traditionally with some incompatibilities and extensions);
PL/SQL, which is procedural programming language tightly integrated with a traditional SQL.
This two things are really different. Even there are a common questions about performance affected by switching context between SQL and PL/SQL engines and mostly caused by improper procedures design.
PL/SQL as a procedural language can access a rich set of APIs, provided by Oracle as a set of built-in packages. Among others there are a number of packages directly related to network communication protocols and standards: UTL_TCP, UTL_URL, UTL_SMTP, UTL_MAIL, UTL_INADDR, UTL_HTTP, HTP, HTF, DBMS_LDAP.
Needs to be said, that there are a set of APIs, provided to support publishing of PL/SQL code on the web. Set of OWA_xxxx packages supports access through mod_plsql. Another thing is a support for publishing SOAP web services in Oracle XML DB.
If you need to unload data from Oracle to web service on a schedule then look at DBMS_SCHEDULE and DBMS_JOB packages to start unload procedures periodically.
Most of this system packages implemented on Java and it's possible to write your own Java extensions callable from PL/SQL.
P.S. There are a UTL_DBWS package dedicated for implementation of calls to SOAP services from Oracle Database, but seems that it produces more problems than solves and I can't find reference to it in 11g documentation (10g only).
P.P.S. Some statements may be slightly inaccurate or contain exaggerations, but that should be enough to understand the overall picture.
I need to generate custom reports using Sonar sql server database data. The structure of the database is quite confusing me. How can I get below details of my project?
LoC(lines of code)
Rule Compliance %
Comment %
Public Documented API %
Security Violations
Violations (excluding Info)
Duplicated Line %
Once I get these details how can I stucture my report because root data is having many childs.
I think you probably really want to use the web services to extract data, rather than reading from the database. See http://docs.codehaus.org/display/SONAR/Web+Services for documentation.
I don't recommend to directly request database because it's not considered as an API. It deeply evolves over time.
There are currently two reporting plugins that generate PDF :
http://docs.codehaus.org/display/SONAR/Sonar+PDF+Plugin (open-source + commercial edition)
http://www.sonarsource.com/products/plugins/reporting/report/ (commercial)
If you want to generate your own report, then you should implement a plugin or request web services from a dedicated application.
My company needs to migrate data from a Taleo system to a new HR system.
A little research suggests that traditional ETL may not work against the Taleo cloud based system, but I don't know enough about the setup and am trying to learn.
Does anyone have experience migrating HR data from Taleo to another system, and, if so, how did you do it, and was traditional ETL an option?
Thanks
How you access Taleo depends as much on your platform as theirs.
Example: I'm using Windows:
not sure if this is my mistake ~~ vs2010 Add Service Reference fails
Taleo has just released a new version that as has killed a number of companies temporarily.*
Whether your ETL is one time or continous, Taleo provides a .PDF version of their API that works as follows for employee records (I'm only grabbing their employee records). Other records appear to use the same paradigm.
Employee records have two types of fields: fixed and user defined. The fixed fields which I work with in c# are like simple properties of a class and can be accessed with standard .name notation such as taleoItem.ManagerId. The user defined names are in list of "beans" ... for each bean, one looks first at its name ( *foreach (var taleoItem in taleoEmployeeBean.flexValues) ... if (taleoItem.fieldName == "Social Club Member") { ... ). * currently I'm getting zero of the 50+ flexbeans that I normally get and two flexbeans that I've never before seen. as can be expected, until Taleo fixes this breakage, all that I can to is twiddle my thumbs
When Taleo works properly, retrieving data generally works like this.
access a fixed url to get a url for your company;
authenticate via the url retrieved from step 1 to get a session token.
use the session token from step 2 to invoke the various Taleo API methods.
Warning: the Taleo API has documentation errors. Also, the test cases will not necessarily work.
I'm not familiar with Taleo, but according to their website they have features that allow integration via "XML, Web Services, reusable components, and standard APIs". There are many ETL tools on the market that can interface with web services as a source, or you could optionally write your own.
Taleo provides a PDF which described all the calls that can be made. Basically Taleo uses SOAP as web-service for accessing their data.

Without reinventing the wheel, what I can use to manage user sessions in a web application and being able to respond with JSON to ajax requests?
Is there some framework (made for example with Indy components or something like this)?
Note for bounty:
in practice it is enough for me to have a reply with a clear example of a server application that serves json. Somehow a Delphi example of the php example mentioned HERE. (without the DB part, I want to see the basics of what does it mean to send JSON. I have basic knowledge of TIdHTTPServer.)
You can take a look at our Synopse SQLite3 Framework, which was just updated to version 1.11.
It serves the data in pure JSON, ready to be used in any AJAX application.
You can also easily create Services, more precisely Client-Server JSON RESTful Services. In this case, you can even not use SQLite3 for your data storage.
This framework is pure Open Source, compiles/run/is tested for Delphi 6 up to XE, is Unicode ready for all versions of Delphi (it uses UTF-8 internally).
By using this framework, you could be able to create easily also Delphi clients, using JSON data from the same server.
There is no internal User session handling yet. Because there are several way of implementing them, and, since our framework is RESTful, it's therefore stateless: no session is needed.
If you need it, I could easily add HTTP sessions using Cookies. What about the User authentication you are expecting?
Maybe this can help you:

DelphiMVCFramework does this
Some notable features:
RESTful (RMM Level 3) compliant
Can be used in load balanced environment using Redis (http://Redis.io) [dev]
Fancy URL with parameter mappings
Specialied renders to generate text, html, JSON
Powerful mapper to map json to objects and datasets to objects
Can be packaged as stand alone server, apache module (XE6, XE7, XE8) and
ISAPI dll
Integrated RESTClient Works with XE3, XE4, XE5, XE6, XE7
and XE8 Completely unit tested
There is a sample for each functionlities
There is a complete set of trainings about it, but the
samples are included in the project Experimental support for IOCP
[dev]
Server side generated pages using eLua (Embedded Lua) [removed soon]
Specific trainings are available (ask me for a date and a place)
Messaging extension using STOMP (beta)
Community driven (Facebook group https://www.facebook.com/groups/delphimvcframework)
Simple and documented
There are books that talk about the framework
Project web site: https://github.com/danieleteti/delphimvcframework
N.B. I'm the main developer
I would suggest Delphi on Rails, it is an open source REST/MVC/StateLess web framework.
http://code.google.com/p/delphionrails/
It use:
superobject JSON parser
UIB/Firebird JSON driver
Cairo for SVG, PDF, PNG rendering
LUA for scripting/template ...
It is able to serialize automatically Delphi data structures to JSON using the new RTTI introduced in Delphi 2010 & XE.
I would recommend Super Object Toolkit.
http://www.progdigy.com
Example Code:
procedure Share(ARequestInfo: TIdHTTPRequestInfo)
var
ReturnObject: ISuperObject;
begin
ReturnObject := SO();
ReturnObject.B['success'] := false;
AResponseInfo.ContentType := 'application/json';
AResponseInfo.ContentText := ReturnObject.AsJSon();
end;
Daraja HTTP Framework, which uses Indy internally and adds a high level API for "web application contexts" and request mappings, loosely inspired by the Servlet API.
If you already have experience with TIdHTTPServer, you can directly access and adjust the server component according to your needs.
For JSON, you may use the built-in JSON support in newer Delphi versions or a third-party library (e.g. JsonDataObjects).
Disclaimer: I am the developer of the framework
My company is looking into writing a custom application that will need to perform many list item queries across multiple site collections. It will need to run for WSS 3.0 and it 'would be nice' if it worked on WSS 2.0 as well. It won't be designed for MOSS/SPS but again it 'would be nice' if it worked on these platforms. There is no restriction on which .NET version should be used for the solution.
For this type of application, what would be better: the object model/API or SharePoint web services? The primary factor I'm considering is performance, followed by features and functionality. Thanks!
Object model is better as you can gain access to additional features and the full detail of the list items, such as the version history.
The object model is also better for performance (as long as you dispose() your spsite and spweb objects properly).
The Sharepoint object model has some differences between 2 and 3, but if you look at the reference for v2 then it will also work fully with v3.
The web services have not changed at all between v2 and v3, which explains why they do not have any new features of v3.
The reason the object model will win on performance is that you will not be serialising the data as Xml and then transmitting a large chunk of Xml, and then deserialising the Xml. The object model spares your memory and bandwidth.
The first thing to consider is "will my code run on a sharepoint server or remotely ?"
If it's running remotely, you don't
have any choice, use web services
If it's running on a sharepoint
server, I would suggest using object
model, as performance will be
better, you'll have access to more
API and authentication will be
easier (=automatic).
+1 to the other posters.
If you decide to go the OM route then you can compile for both WSS 2.0 and WSS 3.0 from the one source. These should get you started.

Can the OM be used inside an Infopath form? Currently I'm using the web services to pull in the list data I want but I would rather use the OM.
