<div class="jive-rendered-content"><p>I have downloaded the new jbpm-5.1.0.Final-installer-full from JBoss website, and I have started studying jBPM.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I want my Java application to start a process and during process life cycle I want to read the variable data. Quite simple requirement, right?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Well I have defined a variable during process design and I use the following code to start a process instance:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Map<String, Object> params2 = new HashMap<String, Object>();</p><p>params2.put("valor", 20000);</p><p>ksession.startProcess("com.ims.teste.requisicao", params2);</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Then I use the following code to "see" all process instances running(I started other several instance using the code structure):</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>ArrayList<ProcessInstance> a = (ArrayList<ProcessInstance>) ksession.getProcessInstances();</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>And I can get all instances correctly.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Well, now how can I access the variable programatically through the same java application?? I could not find any "get" method that look like a "getVariable" or something like that.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Looking at documentation the best I could find was in jBPM 3 docs using ContextInstance. But it doesn't work with jBPM 5.1. </p><p><span>Link here: </span><a class="jive-link-external-small" href="http://docs.jboss.org/jbpm/v3/userguide/context.html" target="_blank">http://docs.jboss.org/jbpm/v3/userguide/context.html</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>How can I do this in 5.1?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Thank you very much.</p></div>
