Error in package registration while loading state machine from .uml [message #1732751]

Hi,
I am quite new in this field and it's maybe an awkward question. I have a model that contains two state machines. I need to parse this uml in a standalone application. I believe EMF would save tons of time. So, I read EMF tutorial and wrote this code to load the uml file.


public static void main(String[] args) {
	ResourceSet set = new ResourceSetImpl();
	set.getPackageRegistry().put(UMLPackage.eNS_URI, UMLPackage.eINSTANCE);
	set.getResourceFactoryRegistry().getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);
	Resource.Factory.Registry.INSTANCE.getExtensionToFactoryMap().put(UMLResource.FILE_EXTENSION, UMLResource.Factory.INSTANCE);

	Resource res = set.getResource(URI.createFileURI("resources/model.uml"), true);
	res.getContents().get(0);
}

but it gives me the following error,

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/uml2/types/TypesPackage
	at org.eclipse.uml2.uml.internal.impl.UMLPackageImpl.init(UMLPackageImpl.java:1907)
	at org.eclipse.uml2.uml.UMLPackage.<clinit>(UMLPackage.java:83)
	at mp.m2bt.BTGenerator.main(BTGenerator.java:31)

	at java.lang.ClassLoader.loadClass(Unknown Source)
	at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
	at java.lang.ClassLoader.loadClass(Unknown Source)
	... 3 more

I am using the following external jars

org.eclipse.emf.common_2.11.1.v20160208-0816.jar
org.eclipse.emf.ecore.xmi_2.11.1.v20160208-0816.jar

org.eclipse.uml2.uml_5.1.2.v20160201-0816.jar

I also checked these links but still no luck.

I am not sure what did I do wrong. So, could anybody please help me? Thanks.

Hi

By now you should find many links that tell you that you must call
UMLResourcesUtil.init().

Ed, Thanks for your reply.

 UMLResourcesUtil.init(set);

is throwing this runtime error

java.lang.NoClassDefFoundError: org/eclipse/uml2/types/TypesPackage

I tried refreshing/cleaning the project, but still it's this runtime errror. Any idea?

Hi,

> UMLResourcesUtil.init(set); is throwing this runtime error java.lang.NoClassDefFoundError: org/eclipse/uml2/types/TypesPackage

Your problem seems to be a missing jar in the classpath.

From the list of jars in your previous post it seems you are using
Eclipse UML2 5.1.2

> org.eclipse.uml2.uml_5.1.2.v20160201-0816.jar
>

the missing class org/eclipse/uml2/types/TypesPackage
is in jar

org.eclipse.uml2.types_2.0.0.v20160201-0816.jar

You may also found later that you will need :

org.eclipse.uml2.uml.resources_5.1.0.v20160201-0816.jar

Setting up properly the classpath of an Eclipse UML2 standalone program
requires some time and lot of patience, and unfortunately is not
properly documented as the versions evolve, although you find many
useful discussions in the UML2 newsgroup

My own personal approach is to start with a classpath including ALL the
plugins in the "UML2 runtime" zip, and from there removing jars that I
suspect I don't need (mainly edit and codegen named jars) one by one
until I get the minimal classpath.

To download the runtime zip go to
http://www.eclipse.org/modeling/mdt/downloads/?project=uml2

and select "runtime" in the release 5.1.2 section

or directly

http://www.eclipse.org/modeling/download.php?file=/modeling/mdt/uml2/downloads/drops/5.1.2/R201602010816/mdt-uml2-runtime-5.1.2.zip

Vega,
Great! It solves the issue. Now I am getting some more error. I hope UML2 runtime will fix those.
Thanks a lot.
