Habari Client libraries release 2015.02

Habarisoft released new versions of Habari Client libraries for Delphi and Free Pascal application integration with free open source message brokers.

Tested with current message broker versions

  • Apache ActiveMQ 5.11.0
  • Apollo 1.7
  • HornetQ 2.4.0.Final
  • Open MQ 5.1 b09
  • RabbitMQ 3.4.3

Fixes

  • The throughput test application uses the subscribe.receipt=true connection parameter to ensure that the broker is ready before the producer starts sending messages

Improvements

  • Connection factory – As a preparation for further code streamlining between library versions, a new API compatible factory class TBTConnectionFactory is included in this version which will replace TBTJMSConnectionFactory in the next major release
  • Password logging – If Log4D logging is enabled, the passcode header value will be not be logged but replaced with *** in the log output
  • Optional units – Several units which are not covered by basic support have been moved to the source/optional directory (BTMessageTransformer*, BTStreamhelper, SSL support units)
  • Refactorings – Refactorings reduce unit dependencies and hard type casts in several places
  • Cleanup – Removed unused procedure TBTStompClient.Connect(const AURI: IURI)
  • Documentation – More documentation improvements and streamlining between library versions

Habari Web Components with JclDebug stack trace support

The upcoming release of Habari Web Components 2.9 introduces experimental support for stack trace output with JclDebug, part of the open source Jedi Code Library, in addition to the already included support for madExcept stack traces.

Exception stack traces are available in development stage mode, and require linking with detailled map information. Please note that these experimental features are not covered by the standard basic support scheme for Habari Web Components and not guaranteed to work with all versions of Delphi / Free Pascal.

The screenshots below illustrate the output on screen and in the Log4D logging output:

Open source REST client libraries for Delphi

delphi-oop

delphi-oop includes a REST client to consume RESTful web services using your own annotated class (similar to JAX-RS). It supports Google OAuth 2.0 authentication. The library is mostly tested with Delphi XE and hosted on Google Code at https://code.google.com/p/delphi-oop/

Code example: (more examples on the project page)

TODataNorthwindClient = class(TSvRESTClient)
  public
    [GET] [Path('/Customers')] [Consumes(MEDIA_TYPE.JSON)]
    function GetCustomers(): TCustomers; virtual;
  end;

delphi-rest-client-api

This library by Fabricio Colombo to consume RESTful web services supports two implementations, using Indy 10 and WinHTTP. The API was tested in Delphi XE, XE2 and XE3 and is hosted on Github at https://github.com/fabriciocolombo/delphi-rest-client-api

Code example:

var
  vPerson : TPerson;
begin
  vPerson := RestClient.Resource('http://localhost:8080/java-rest-server/rest/person/1')
                     .Accept(RestUtils.MediaType_Json)
                     .Get<TPerson>();

Open source SAX parsers for Delphi and Free Pascal

SAX (Simple API for XML) provides a mechanism for reading data from an XML document that is an alternative to that provided by the Document Object Model (DOM). Where the DOM operates on the document as a whole, SAX parsers operate on each piece of the XML document sequentially.

SAX is supported by several libraries for Delphi and Free Pascal, some open source libraries are:
