    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()); } } }

    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>

    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>
