Tag elements of a sequence diagram in an emx file (UML2) [message #1805198]

Hi ,
I have a .emx file containing a sequence diagram and a class diagram. The sequence diagram represents traces that i got while executing a J2EE application.
I want to know what the different tags represent. For example : <ownedOperation> , <ownedParameter> , <packagedElement xsi:type="uml:ReceiveOperationEvent"> , <packagedElement xsi:type="uml:Class"> ...
I attached an emx file and included a little sample here.
To give you guys an idea of what I'm trying to do, i'm trying to parse the sequence diagram using java to transform it into a JSON file in order to create a call graph.

example :

<packagedElement xsi:type="uml:SendOperationEvent" name="getLocale284"/>
  <packagedElement xsi:type="uml:ReceiveOperationEvent" name="getScreens287" operation="//com.sun.j2ee.blueprints.petstore.control.web.ScreenFlowManager/getScreens.1"/>
  <packagedElement xsi:type="uml:SendOperationEvent" name="getScreens288" operation="//com.sun.j2ee.blueprints.petstore.control.web.ScreenFlowManager/getScreens.1"/>
  <packagedElement xsi:type="uml:ReceiveOperationEvent" name="getScreens292"/>
  <packagedElement xsi:type="uml:SendOperationEvent" name="getScreens293"/>
  <packagedElement xsi:type="uml:Class" name="com.sun.j2ee.blueprints.petstore.control.web.Screen">
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
    <ownedOperation name="getParameter">
      <ownedParameter name="arg1" type="//java.lang.String"/>
      <ownedParameter type="//com.sun.j2ee.blueprints.petstore.control.web.Parameter" direction="return"/>
    </ownedOperation>
</packagedElement>

Hi

Your *.emx file appears to be a 'standard' UML 2.3 file using the Eclipse UML form of the UML metamodel. You should be able to load that using the corresponding Eclipse (MDT) UML2 tooling and get an equivalent EMF Java model instance. No need for you to write a parser.

However UML 2.3 was a long time ago. UML 2.4 removed the MessageOccurrenceSpecification::event association used extensively by your model, so it fails to load on the current UML 2.5 support.

The migration guide [1] refers to [2] which explains that OccurrenceSpecification::event was removed in UML 2.4 8 years ago since events were generally unnecessary and just required artificial bloated pseudo-events.

You should therefore eliminate and use a modern Eclipse, or live with them and continue to use the seriously vintage Eclipse, UML and Java.

Either way, your file should load without trouble.

Regards

Thanks for the clarification. I have managed to upgrade the emx file to 2.4.1 using IBM Rational software architecture. and i have started reading the documentation corresponding to that version of UML. And about the Eclipse (MDT) UML2 , not writing a parser would absolutely save me a lot of time. I will definitely look into that. do you have any tips on where to start? Thanks.
