BBCamundaBootDemo

This is one demo of Camunda (7.8) running on Spring Boot (1.5.10) and Java 8.

Lessons learned

Here are lessons learned doing this demo - it took me considerable time to figure out, and solve "small" problems.

Embedding Forms

When using Spring Boot and embedding forms in Camunda Modeler, Form Key shall be adapted.

From:

embedded:app:forms/<>.html

to

embedded:/forms/<>.html

Using Connector and Spin

To use Camunda Connector and Spin, enable plugins in Engine and put this into your application/configuration Class (I wonder why is this not enabled by default ?)

	@Bean
	public ConnectProcessEnginePlugin connectProcessEnginePlugin() {
	  return new ConnectProcessEnginePlugin();
	}

Cammunda Connector Errors

To handle (technical ?) errors when talking with external web services set Error Code to:

org.camunda.connect.ConnectorException

Use lambdas

To implement JavaDelegates, use lambdas - very short and practical:

	@Bean(name="javaDelegate")
	public JavaDelegate sayHelloDelegate() {
		
	    return execution -> System.out.println("Logging something from javaDelegate... Hello");
	}

EE Camunda

To authentificate access to EE repository, there is a need to adapt (or create) ~/.m2/settings.xml with similar content

	<servers>
		<server>
			<id>Camunda-EE-Repository</id>
			<username>...</username>
			<password>...</password>
		</server>
	</servers>

H2 Database

To se content of H2 in memory database, use following URL in web browser:

http://localhost:8080/h2-console

and following database URL (leave user sa without password):

jdbc:h2:mem:testdb

Demo table is called computers.

SSH execution added

Try to prepare and use docker image as host with SSHD.
