    jbpm web application development in tomcat

    yogeen honnavar Newbie

      Dear users,

       

      We are primarily working with tomcat. now we have installed jbpm in tomcat. although this provides the jbpm console in tomcat. we would like to know what is the way to develop a new web application in tomcat that uses jbpm. can anybody suggest suitable links, pointers to this.

       

      regards

          Hi Yogeen,

           

          The easiest way to do this, use run ant "create.user.webapp" on the build file present in install folder it gives u a user-webapp structure created (normal web app structure) with dependency library copied in WEB-INF/lib folder.

           

          This means you are using jBPM as just another library in your web-app. If you are integrating it with Spring you will get lots of help. And its easy to integrate it with Spring.

           

          You can use sample applicationContext.xml file present in jbpm-4.3/install/src/cfg/spring/ folder. Once you have processEngine bean you can go ahead and build all the services like repository, execution, management, etc... and inject them wherever you need them.

           

          also use spring.jbpm.cfg.xml (available at install/src/cfg/jbpm) for configuring your jbpm.

           

          Ping back if you need further help.

           

          Cheers!

            can you pls give some hints regarding using the jbpm engine within tomcat after we have created a webapp using ant "create.user.webapp". is there any documentation/turorial available ?

              Hi Yogeen,

               

              No Spring is not the only way to create jBPM process.

               

              1. You can use jBPM in your standalone application using plain POJO

              2. Use OpenEJB plugin for tomcat to get EJB container support in Tomcat since tomcat is mainly JSP/Servlet container.

              3. Use Spring (Standalon/Webapplication)

              4. Use jBPM in servlets.

               

              So it all depends on you how u want to access jBPM.

               

              I would rather ask you to refer the User Guide & Develop Guide to understand how you can build processes and deploy them. You can deploy processes as a archive or through your POJO/Spring Bean/EJB... using its repository service.

               

              User Guide Link: http://docs.jboss.com/jbpm/v4/userguide/html_single/#introduction

               

              It explains different ways to build & deploy processes.

               

              Once you go through this document you will be more comfortable.

               

              Basic Steps:

               

              1. Create process engine

              2. Get required services reference

              3. Deploy process if not yet done

              4. Start Process Instance

              5. Signal waiting states if any

              .... so on

               

              You can carry out steps in whichever manner you like.

               

              Important:

               

              1. Explains you how to create process graphically & deploy it. http://docs.jboss.com/jbpm/v4/userguide/html_single/#graphicalprocessdesigner

              2. Explains about services, which you can use inside you code to create/deploy/manage processes. http://docs.jboss.com/jbpm/v4/userguide/html_single/#processdefinitionprocessinstanceandexecutions

               

              Try it.
