<div class="jive-rendered-content"><p>Hi</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am testing the integration of jbpm 5 with jboss soa platform. So far, i downloaded soa-p-5.3.1.GA.zip and soa-p-5.3.1.GA-jbpm5.zip. Also, according with the instructions in the readme file of the soa-p jbpm 5 file, i downloaded the brms-p-5.3.1.GA-deployable.zip and deployed its content in the soa-p platform server </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am running the soa platform against an oracle database; so i modified all files to use that database.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Also, i created a esb project and deployed to the server. This esb project has a .bpmn file that represents my process definition; i can interact with this process via the esb project, that means, i can start a new instance of the process using the esb command available for that operation</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>But i cannot access the form that i defined for a human task inside the process. It is giving me this problem:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>freemarker.core.InvalidReferenceException: Expression revRequestId is undefined on line 15, column 34 in LoanRevission.</p><p> freemarker.core.TemplateObject.assertNonNull(TemplateObject.java:124)</p><p> freemarker.core.Expression.getStringValue(Expression.java:118)</p><p> freemarker.core.Expression.getStringValue(Expression.java:93)</p><p> freemarker.core.DollarVariable.accept(DollarVariable.java:76)</p><p> freemarker.core.Environment.visit(Environment.java:209)</p><p> freemarker.core.MixedContent.accept(MixedContent.java:92)</p><p> freemarker.core.Environment.visit(Environment.java:209)</p><p> freemarker.core.Environment.process(Environment.java:189)</p><p> freemarker.template.Template.process(Template.java:237)</p><p> org.jbpm.integration.console.forms.AbstractFormDispatcher.processTemplate(AbstractFormDispatcher.java:128)</p><p> org.jbpm.integration.console.forms.TaskFormDispatcher.provideForm(TaskFormDispatcher.java:109)</p><p> org.jbpm.integration.console.forms.FormDispatcherComposite.provideForm(FormDispatcherComposite.java:50)</p><p> org.jboss.bpm.console.server.FormProcessingFacade.provideForm(FormProcessingFacade.java:205)</p><p> org.jboss.bpm.console.server.FormProcessingFacade.renderTaskUI(FormProcessingFacade.java:127)</p><p> sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)</p><p> sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)</p><p> sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)</p><p> java.lang.reflect.Method.invoke(Method.java:601)</p><p> org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:140)</p><p> org.jboss.resteasy.core.ResourceMethod.invokeOnTarget(ResourceMethod.java:255)</p><p> org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:220)</p><p> org.jboss.resteasy.core.ResourceMethod.invoke(ResourceMethod.java:209)</p><p> org.jboss.resteasy.core.SynchronousDispatcher.getResponse(SynchronousDispatcher.java:519)</p><p> org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:496)</p><p> org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:119)</p><p> org.jboss.resteasy.plugins.server.servlet.ServletContainerDispatcher.service(ServletContainerDispatcher.java:208)</p><p> org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:55)</p><p> org.jboss.resteasy.plugins.server.servlet.HttpServletDispatcher.service(HttpServletDispatcher.java:50)</p><p> javax.servlet.http.HttpServlet.service(HttpServlet.java:717)</p><p> org.jboss.bpm.console.server.util.GWTJsonFilter.doFilter(GWTJsonFilter.java:59)</p><p> org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)</p><p style="min-height: 8pt;

but those instances does not show in the business-central console, or when i access the REST api of the business-central-server; i know that these instances exists, because i can see the tasks that are create for a user, and these tasks has an instance id associated with them; but the instances does not appear in the console or via the REST api, why ??</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The other problem i am facing is that, i created a form to start the process, to test if it could be ran without the esb, but when i used this form to start an instance i get this error:</p><p style="min-height: 8pt;
