17. Andreas Martin - Page 17 camunda BPM – Java EE service 5. Process Layer @Named @Stateless public class CustomerService { @Inject @ProcessVariable public Object customerId; @Inject private BusinessProcess businessProcess; @EJB CustomerEJB customerEJB; public void loadCustomer() { Customer customer = customerEJB.findCustomerById(Long .valueOf((String) customerId)); if (customer != null) { businessProcess.setVariable("customerFirstName", customer.getFirstName()); businessProcess.setVariable("customerLastName", customer.getLastName()); } } }
18. Andreas Martin - Page 18 camunda BPM – HTML forms 5. Process Layer <form class="form-horizontal"> <div class="control-group"> <label class="control-label">Customer ID</label> <div class="controls"> <input form-field type="string" name="customerId"></input> </div> </div> <div class="control-group"> <label class="control-label">Amount</label> <div class="controls"> <input form-field type="number" name="amount"></input> </div> </div> </form>
19. Andreas Martin - Page 19 Hands-on 5 BPM CDI WEB APPLICATION 5. Process Layer
20. Andreas Martin - Page 20 Hands-on 5 2. Derive use cases from workflow graph. 3. Extract service model from use case model. 5. Process Layer 1. We are going to implement the “Loan Approval” process.
21. Andreas Martin - Page 21 Hands-on 5 4. Import “hands-on-5” project. 5. Model the execution graph using the workflow graph as blueprint. 6. Implement the services as modelled in service model. 7. The project already contains HTML forms – inspect them. 8. Add the service calls to the BPMN model and make sure that process model is executable. 9. Add the form references and conditions to the BPMN model. 10. Deploy and run the workflow. 5. Process Layer

23. Andreas Martin - Page 23 Database Connection …will be used for the next hands-on  Modify the MySQL_premscis-xa-ds.xml file:  When using a Web Project in Eclipse, it is possible to deploy a datasource using a JBoss datasource file (…-ds.xml)  This file must be placed under: Project +---src\main\webapp\WEB-INF ¦ faces-config.xml ¦ jboss-web.xml ¦ MySQL_premscis-xa-ds.xml  Choose another student ‘number’ (DatabaseName) to avoid overwriting.  When using Camunda BPM in a Java EE environment you have to implement a “xa-datasource” 5. Process Layer <?xml version="1.0" encoding="UTF-8"?> <datasources> <xa-datasource jndi-name="java:jboss/datasources/MySQL_premscis_xa" pool-name="MySQL_premscis" enabled="true" use-java- context="true"> <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> <xa-datasource-property name="PortNumber">80</xa-datasource-property> <xa-datasource-property name="ServerName">mature.iwi.wirtschaft.fhnw.ch</xa-datasource-property> <xa-datasource-property name="DatabaseName">premscis</xa-datasource-property> <driver>mysql-connector-java-5.1.32-bin.jarcom.mysql.jdbc.Driver_5_1</driver> <security> <user-name>premscis</user-name> <password>premscis</password> </security> </xa-datasource> </datasources>
