<div class="jive-rendered-content"><p>Hi,</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Looks like you have a problem with the installation of the eclipse plugins for the BPMN Editor. I suggest you try out the following 2 methods :</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><strong style="text-decoration: underline;">Using the BPMN2.0 Editor</strong></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. Clean up to ensure that you start from fresh ( $ ant clean.demo )</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2. Start with a clean eclipse installation ( Indigo SR2 version mentioned in the build script ). Ensure that your eclipse home is properly set</p><p>     to your downloaded location.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>3. Ensure that eclipse drools JBPM plugin and eclipse GEF plugin  are downloaded and installed into the appropriate locations as mentioned in the</p><p>     build script. The build takes care of these but you have to ensure that it is done properly by cross-checking it</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>4. Set your eclipse home to point to the eclipse home directory where you downloaded eclipse in the build.properties file</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>5. Then follow Chapter 9 in the JBPM5.2 user guide for installing the graphiti and BPMN Editor plugins into eclipse</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>   They have sugested Grpahiti 0.7.1 and BPMN2.0 but did not work for me. There were some compatibility issues.</p><p>    So I installed Graphiti version 0.8.1 and BPMN2.0</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>6. Now start your demo and things should work fine and you should be able to use the BPMN editor to create the diagrams</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>   $ ant start.demo</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="text-decoration: underline;"><strong>Using the Designer</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>You can also create BPMN diagrams using the designer. The designer has got a nice user interface. And you can save revisions into the </p><p>Drools Guvnor. You can later on import these artifacts into eclipse. The basics of the Designer is explained in Chapter 10 of the JBPM5.2 user guide.</p><p>That should be sufficient to start off with the designer. Here are the steps :</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>1. Ensure that your JBOSS App Server is up and runing. Ensure that the H2 database is started as well. You can see these printed when you run</p><p>    </p><p>    $ant start.demo</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>2. Access the Drools Guvnor using the folowing link</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span>    </span><a class="jive-link-external-small" href="http://127.0.0.1:8080/drools-guvnor" target="_blank">http://127.0.0.1:8080/drools-guvnor</a></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    It should open up the Guvnor application. The Guvnor is a repository for storing artifacts. You can use one of the logins mentioned </p><p>    in the users.properties file in the auth folder ( like krisv, mary, john etc. )</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>3. The designer is invoked through the Guvnor application.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    Using the create -> new you can create a new BPMN drawing and then you can save it in the guvnor. You can save it either as part</p><p>     of the default package or storage space.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>4. This can be imported into eclipse using File -> import -> Guvnor -> Package -> Your BPMN diagram</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Here are some links to useful docs :</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><strong style=": ; font-size: 10pt; font-family: 'Book Antiqua', serif; text-decoration: underline;">JBPM5.2 User Guide  </strong></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="font-size: 10pt; font-family: 'Book Antiqua', serif;"> </span><a class="jive-link-external-small" href="http://docs.jboss.org/jbpm/v5.2/userguide/">http://docs.jboss.org/jbpm/v5.2/userguide/</a>  </p><p><span style="font-family: 'Book Antiqua', serif; text-decoration: underline;"><br/></span></p><p><span style="font-size: 10pt; font-family: 'Book Antiqua', serif; text-decoration: underline;"><strong>Drools Guvnor Manual</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="color: #0000ff; text-decoration: underline;"><a class="jive-link-external-small" href="http://docs.jboss.org/drools/release/5.3.0.Beta1/drools-guvnor-docs/html_single/index.html"><span style="font-size: 10pt; font-family: 'Book Antiqua', serif;">http://docs.jboss.org/drools/release/5.3.0.Beta1/drools-guvnor-docs/html_single/index.html</span></a></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The designer is a very powerful tool and I believe we can also use it to create forms which we may need for human tasks.</p><p>You can also validate your BPMN process using the Designer. I am also a newbie and yet to explore the designer completely. </p><p>So I have just shared whatever I know about the Designer.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p><span style="text-decoration: underline;"><strong>Article on JBPM Designer</strong></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p lang="zxx"><span style="color: #000080; text-decoration: underline;"><a class="jive-link-external-small" href="http://surdilovic.wordpress.com/" target="_blank">http://surdilovic.wordpress.com/</a></span></p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Hope this helps.</p></div>
