<div><br></div> All, re-sending this e-mail. Anyone touching .proto files please make sure you follow the instructions bellow to install the protobuf plugin. I will add that to a wiki page.<div><br></div><div> Edson<br>

<br></div> All,<div>
<br></div><div> As we started using Protobuf, it is important to know how you make changes to .proto files and how to compile them. Easiest way:</div><div><br></div><div>1. Download protobuf compiler from: <a href="http://code.google.com/p/protobuf/downloads/list" target="_blank">http://code.google.com/p/protobuf/downloads/list</a></div>
<div><br></div><div>2. Install protobuf-dt eclipse plugin as detailed here: <a href="http://code.google.com/p/protobuf-dt/" target="_blank">http://code.google.com/p/protobuf-dt/</a></div><div><br></div><div>3. Configure the destination directory to generate the java files as detailed in step 2 here:</div>
<div><br></div><div><a href="http://code.google.com/p/protobuf-dt/wiki/IntegrationWithProtoc" target="_blank">http://code.google.com/p/protobuf-dt/wiki/IntegrationWithProtoc</a><br></div><div><br></div><div>Set the "Java Output Directory" to: src/main/java</div>
<div><br></div><div>4. VERY IMPORTANT FOR JBPM: jBPM Flow project has a .proto file that extends the data types defined in the .proto file in Drools Core, so you need to configure the protobuf import path as detailed here:</div>
<div><br></div><div><a href="http://code.google.com/p/protobuf-dt/wiki/ImportPaths" target="_blank">http://code.google.com/p/protobuf-dt/wiki/ImportPaths</a></div><div><br></div><div>Add the following import paths to the jbpm-flow project:</div>
<div><br></div><div>${your drools-core project in eclipse}/src/main/resources</div><div>${your_drools_flow_project}/src/main/resources</div><div><br></div><div> After doing that, when you edit and save the .proto files, eclipse will automatically compile and regenerate the java source code for them.</div>
