I have a problem in installing activiti I tried to install it in eclipse but I didn't know how to begin using it .can someone  show me how?
second I have tried it by another way by installing apache ant server but when I want to do the dos step to open it (open the program by the server) it gives a wrong error message , my problem is how to save this file in apache server?
can someone show how to install it in steps (activiti 5.9) or give me a good link that gives a good explanation about it , I've tried many links but It didn't all worked with me can someone help?
also can someone show me a good reference that explain it ?

do something like ps -ef | grep -i java

look for java processses that are still running, presumably a tomcat instance or something like that. Then do kill -5 <processid>

You can find hundreds of examples for this kind of stuff with a Google search, there's nothing specific to Activit about it.

The '9092 in use' error refers to the H2 database. This is most likely due to you running 'ant demo.start' without running 'ant demo.stop' first. This means that the H2 instance is still running and you're trying to run a second instance leading to a port conflict.

What's more relevant is that the Tomcat version in your 404 error is 6.0.29, but the version of Tomcat that comes with your Activiti package is 6.0.32
This means that you're not hitting the Activiti Tomcat container with your request, hence the 404.

So, do you have another version of Tomcat installed? If so, are your CATALINA_* variables set to point to this version of Tomcat? That's the problem I had and I fixed it by setting CATALINA_HOME, CATALINA_BASE and CATALINA_TEMP to point to my Activiti Tomcat… things worked fine then.

On a related note, I think this might actually be a common issue and so I've opened a JIRA ticket http://jira.codehaus.org/browse/ACT-1226
