Gurvinderpal Narula [http://community.jboss.org/people/groovenarula] created the discussion "Error accessing 'Process Overview' menu in jbpm-console." To view the discussion, visit: http://community.jboss.org/message/633720#633720 -------------------------------------------------------------- I'm evaluating jBPM for an upcoming project. I'm evaluting jBPM 5.1.Final on Mac OS X 10.7.2 on jdk 1.6.0 (build 1.6.0_26-b03-383-11A511). Executing 'ant start.demo' launching jboss and even launches eclipse successfully with the console output as follows : Buildfile: /Users/gnarula1/Documents/projects/jbpm-installer/build.xml download.h2.check:      [echo] Checking h2 download ... download.h2: start.h2: start.jboss: start.eclipse: start.human.task:     [mkdir] Created dir: /Users/gnarula1/Documents/projects/jbpm-installer/task-service/target     [javac] /Users/gnarula1/Documents/projects/jbpm-installer/build.xml:500: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds     [javac] Compiling 1 source file to /Users/gnarula1/Documents/projects/jbpm-installer/task-service/target     [javac] /Users/gnarula1/Documents/projects/jbpm-installer/task-service/src/org/jbpm/DemoTaskService.java:49: warning: [unchecked] unchecked cast     [javac] found   : java.lang.Object     [javac] required: java.util.Map<java.lang.String,org.jbpm.task.User>     [javac]         Map<String, User> users = ( Map<String, User> ) eval( reader, vars );       [javac]                                                             ^     [javac] /Users/gnarula1/Documents/projects/jbpm-installer/task-service/src/org/jbpm/DemoTaskService.java:54: warning: [unchecked] unchecked cast     [javac] found   : java.lang.Object     [javac] required: java.util.Map<java.lang.String,org.jbpm.task.Group>     [javac]         Map<String, Group> groups = ( Map<String, Group> ) eval( reader, vars );         [javac]                                                                ^     [javac] Note: /Users/gnarula1/Documents/projects/jbpm-installer/task-service/src/org/jbpm/DemoTaskService.java uses or overrides a deprecated API.     [javac] Note: Recompile with -Xlint:deprecation for details.     [javac] 2 warnings      [copy] Copying 2 files to /Users/gnarula1/Documents/projects/jbpm-installer/task-service/target      [java] SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".      [java] SLF4J: Defaulting to no-operation (NOP) logger implementation      [java] SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.      [java] Task service started correctly !      [java] Task service running ...

If this issue is caused because of running on a Mac, then please let me know and I'll try a different platform.
