<div class="jive-rendered-content"><p>I have done a Jbpm 4.4 Spring 3.0.5 integration in a webapp.. So I am your man <span> :) </span> .. believe me it is tricky.. </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Before you start to integrate stuff you need couple of files ready .</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I am assuming you are using hibernate .. because jbpm itself uses hibernate for data persistance..  (The version to use will be 3.5 , 3.6 wont work )</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. jbpm.cfg.xml  - check atttachment - default attached. Keep it in the src directory of your project.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2. jbpm.hibernate.cfg.xml - See attached,  again keep it int the src directory (notice the custom written hibernate dialect , for some reason hibernate was messing up type mappings for oracle 10g in my case) , jbpm.hibernate.cfg.xml file is auto picked by the jbpm api (check jbpm.tx.hibernate.cfg.xml - this file includes jbpm.hibernate.cfg.xml , so jbpm.tx.hibernate.cfg.xml had to be included in jbpm.cfg.xml ), hence no need to mention jbpm.hibernate.cfg.xml in any cfg files you create.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>3. jbpm4-context.xml - See attached,  again keep it in the src directory</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>4. Create your normal hibernate.cfg.xml to do application specific db operations.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>5. jbpm specific hibernate operations are kept in jbpm.hibernate.cfg.xml (mentioned in point number 2)</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>6.
