But, unfortunately I don’t have any knowledge on JBMP. So, I would like to clarify with you guys. The queries are given below:</span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><strong style=": ; font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif'; text-decoration: underline;">The proposed architecture</strong></p><ol style="list-style-type: decimal;"><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">1. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">The architecture is </span><span style="font-size: 10.5pt; font-family: Wingdings;">à</span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';"> Our JBoss based Web App will call JBPM thru java call. </span></li><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">2. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">And we will not use JBPM user interface (GUI) but we use our Bboss application’s UI.</span></li><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">3. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">>From the JBoss UI’s button click (Submit/Approve etc), JBoss app calls JBPM to </span><ol style="list-style-type: decimal;"><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">a. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">create workflow process instance.</span></li><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">b. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">Move process instance from one stage to another stage.</span></li></ol></li><li><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">4. </span><span style="font-size: 10.5pt; font-family: 'Arial Narrow','sans-serif';">Meaning, we have Maker/Checker (Authorization) functionality exists.
