--------------------------------------------------------------
Hi,
i tryed to make the
https://community.jboss.org/people/bpmn2user/blog/2011/09/21/jbpm5-web-ex... bpmn2user
JBPM5 Web Example running in eclipse and tomcat 6.0.35 (before deploying its war directly
in the tomcat webapp directory)
i thought that i just had to execute it on maven (mvn eclipse) and then import(**) and
run it after setting the bitronix configuration(***) to the server as written in the web
page example but i actually have had alot problems :
1)- a classloading problem as servlet .java files were under the src/main/java, i fixed
this by changing servlet's packages location to the WebContent/WEB-INF.(i wish to know
if i can keep the example builld path show in the example webpage without having that
problem but i dont know how..now i still not sure about the right project layout), here is
my current layout :
https://community.jboss.org/servlet/JiveServlet/showImage/2-740498-18720/...
https://community.jboss.org/servlet/JiveServlet/downloadImage/2-740498-18...
2)- alot of missing jars which i had to add to the tomcat/lib directory (i think it s
weird that i had to add these same jars whose maven's dependancies were all(or most of
them ) written in the pom project file.. tomcat cannot directly use the maven local
repository ?!! why tomcat doesn t refer to the pom of the webapp?) here is my current
tomcat lib directory (but i still have a NoClassDefFoundError: org/slf4j/LoggerFactory to
solve and i may change it again):
https://community.jboss.org/servlet/JiveServlet/showImage/2-740498-18719/...
https://community.jboss.org/servlet/JiveServlet/downloadImage/2-740498-18...
3) i also have a "cvc-complex-type.2.4.d: Invalid content was found starting with
element 'param-name'. No child element is
expected at this point" on the web.xml which i failed to solve (maybe it doesn t
really matter to keep it and run the application )
please, , i would like to know more details on these required jars on the tomcat/lib . i
wish to find a video tutorial about this interesting example !!
Thanks.
_______________________
(**) i set the dynamic web module 2.5 and java 1.6 as project facets in this step.
(***):the bitronix configuration needs the native library and the APR which was too hard
to build with visual studio c++ as it need knowledges on it, the easy solution was to
install tomcat from the binary installer.

i ve fixed the project folders layout like this and now i ve the index.jsp displayed :
https://community.jboss.org/servlet/JiveServlet/showImage/2-740647-18722/...
https://community.jboss.org/servlet/JiveServlet/downloadImage/2-740647-18...
i also have resolved slf4j problems (refering to http://www.slf4j.org/manual.html
http://www.slf4j.org/manual.html) and my current tomcat/lib look like this :
https://community.jboss.org/servlet/JiveServlet/showImage/2-740647-18723/...
https://community.jboss.org/servlet/JiveServlet/downloadImage/2-740647-18...
finally i ve these problems :

The solution was to add all jars declared on the project pom to the tomcat/lib...i really
wonder why they have been declared in the pom if not to be used by the server!!!
