[jbpm-issues] [JBoss JIRA] Updated: (JBPM-2619) couldn't deserialize object

[ https://jira.jboss.org/jira/browse/JBPM-2619?page=com.atlassian.jira.plug... ] Robin Thomas updated JBPM-2619: ------------------------------- Description: I have set a bean object as process instance variable. Say Employee which has getter and setter methods for all the fields. Map<String,Object> variables =new HashMap<String,Object>(); variables.put("employee",new Employee("dfdf","dfsd","","sdfsd")); ProcessInstance processInstance = executionService.startProcessInstanceByKey(processDefKey, variables); while retriving using the below code : TaskService taskService = processEngine.getTaskService(); Set<String> a=taskService.getVariableNames("107"); taskService.getVariables("107",a ); gets the following error: Exception in thread "main" org.jbpm.api.JbpmException: couldn't deserialize object at org.jbpm.pvm.internal.type.converter.SerializableToBytesConverter.revert(SerializableToBytesConverter.java:65) at org.jbpm.pvm.internal.type.Variable.getValue(Variable.java:104) at org.jbpm.pvm.internal.model.ScopeInstanceImpl.getVariable(ScopeInstanceImpl.java:183) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.hibernate.proxy.pojo.javassist.JavassistLazyInitializer.invoke(JavassistLazyInitializer.java:197) at org.jbpm.pvm.internal.model.ExecutionImpl_$$_javassist_4.getVariable(ExecutionImpl_$$_javassist_4.java) at org.jbpm.pvm.internal.model.ScopeInstanceImpl.getVariable(ScopeInstanceImpl.java:188) at org.jbpm.pvm.internal.cmd.GetTaskVariablesCmd.execute(GetTaskVariablesCmd.java:53) at org.jbpm.pvm.internal.cmd.GetTaskVariablesCmd.execute(GetTaskVariablesCmd.java:35) at org.jbpm.pvm.internal.svc.DefaultCommandService.execute(DefaultCommandService.java:42) at org.jbpm.pvm.internal.tx.StandardTransactionInterceptor.execute(StandardTransactionInterceptor.java:54) at org.jbpm.pvm.internal.svc.EnvironmentInterceptor.execute(EnvironmentInterceptor.java:46) at org.jbpm.pvm.internal.svc.RetryInterceptor.execute(RetryInterceptor.java:55) at org.jbpm.pvm.internal.svc.TaskServiceImpl.getVariables(TaskServiceImpl.java:194) at com.test.AppClient.main(AppClient.java:89) Caused by: java.lang.ClassNotFoundException: com.mbrdi.travelservice.client.TestBO at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Unknown Source) at java.io.ObjectInputStream.resolveClass(Unknown Source) at java.io.ObjectInputStream.readNonProxyDesc(Unknown Source) at java.io.ObjectInputStream.readClassDesc(Unknown Source) at java.io.ObjectInputStream.readOrdinaryObject(Unknown Source) at java.io.ObjectInputStream.readObject0(Unknown Source) at java.io.ObjectInputStream.readObject(Unknown Source) at org.jbpm.pvm.internal.type.converter.SerializableToBytesConverter.revert(SerializableToBytesConverter.java:63) was: I have stored a bean object (Employee)as process variable.
