forum : http://www.jboss.org/index.html?module=bb&op=viewtopic&t=159875

two points I noticed :

1/
http://docs.jboss.com/jbpm/v4.0/userguide/html_single/#deployingaprocess

the given example is :
"
long deploymentDbid = repositoryService.createDeployment()
.addResourceFromClasspath("org/jbpm/examples/services/Order.jpdl.xml")
.deploy();
"

but in fact deploy() returns a String

could someone correct it ?

2/
same kind of inaccurracy : the id in table 5.1 and 5.2 has a format like

{key}:{version} (with : between key and version)
whereas the text above states :
"The id will have format {key}

-

{version}

with a dash between key and version"
and paragraph 5.6.2 seems to use this "dash" format too

if I may insist doc quality really matters...

a third point :

3/ in § 6.2.3.1. Decision conditions there should be an image with url
http://docs.jboss.com/jbpm/v4.0/userguide/html_single/images/process.decision.png

but there is nothing at this URL, so that the image does not show. I suppose the correct URL would be :
http://docs.jboss.com/jbpm/v4.0/userguide/html_single/images/process.exclusive.png

idem with the two follwing images

4/ Figure 6.20 is not accurate eithet, I'd say

5/ Figure 6.24 also not correct

6/ in the listings and comments §6.5.1. Event listener example there is
"LogListener will maintain a list of logs in a static member field:"
but it is obviously not a static field. But those comments may be confusing, because the concept of process variable is new for most reader, I think. Plus it is wrong
