Bonita

Since Camel 2.19

Only producer is supported

Used for communicating with a remote Bonita BPM process engine.

URI format

bonita://[operation]?[options]

Where operation is the specific action to perform on Bonita.

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

The component level is the highest level which holds general and common configurations that are inherited by the endpoints. For example a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

Configuring components can be done with the Component DSL, in a configuration file (application.properties|yaml), or directly with Java code.

Configuring Endpoint Options

Where you find yourself configuring the most is on endpoints, as endpoints often have many options, which allows you to configure what you need the endpoint to do. The options are also categorized into whether the endpoint is used as consumer (from) or as a producer (to), or used for both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders, which allows to not hardcode urls, port numbers, sensitive information, and other settings. In other words placeholders allows to externalize the configuration from your code, and gives more flexibility and reuse.

The following two sections lists all the options, firstly for the component followed by the endpoint.

Component Options

The Bonita component supports 2 options, which are listed below.

Name Description Default Type

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

boolean

Endpoint Options

The Bonita endpoint is configured using URI syntax:

bonita:operation

with the following path and query parameters:

Path Parameters (1 parameters)

Name Description Default Type

operation (producer)

Required Operation to use.

Enum values:

  • startCase

BonitaOperation

Query Parameters (6 parameters)

Name Description Default Type

hostname (producer)

Hostname where Bonita engine runs.

localhost

String

port (producer)

Port of the server hosting Bonita engine.

8080

String

processName (producer)

Name of the process involved in the operation.

String

lazyStartProducer (producer (advanced))

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

password (security)

Password to authenticate to Bonita engine.

String

username (security)

Username to authenticate to Bonita engine.

String

Body content

For the startCase operation, the input variables are retrieved from the body message. This one has to contains a Map<String,Serializable>.

Examples

The following example start a new case in Bonita:

from("direct:start").to("bonita:startCase?hostname=localhost&amp;port=8080&amp;processName=TestProcess&amp;username=install&amp;password=install")

Dependencies

To use Bonita in your Camel routes you need to add a dependency on camel-bonita, which implements the component.

If you use Maven you can just add the following to your pom.xml, substituting the version number for the latest and greatest release (see the download page for the latest versions).

<dependency>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-bonita</artifactId>
  <version>x.x.x</version>
</dependency>
