[XPand] Apply oaw to xpand project error [message #930173]

Tue, 02 October 2012 00:39

Eclipse User

Hi everyone,
I'm new to oAW and xpand, I'm trying to apply workflow to my xpand project, can you please to help me this issue?
Here is my xpand code:

«DEFINE main FOR ARRoot::BMD»
«FILE "Hello.h" -»
Number = «this.Example.parameter.value»
«ENDFILE»
«ENDDEFINE»

Here is my workflow:

<?xml version="1.0" encoding="utf-8"?>
<workflow>
	<property name="baseDir" value="./"/>
 	<property name='src-gen' value="${baseDir}/gen" />
 	<!-- load model and store it in slot 'model' -->
    <component class="org.openarchitectureware.xsd.XMLReader">
    	<uri value="./default.arxml"/>
    	<modelSlot value="EPC" />
		<metaModel id="mm" class="org.openarchitectureware.xsd.XSDMetaModel">
            <schemaFile value="${baseDir}/autosar_4-0-3.xsd"/>
        </metaModel>
    </component>
	
    <component class="org.openarchitectureware.xpand2.Generator">
    	<metaModel idRef="mm" />
		<expand value="src::mytemplate::main FOR EPC"/>
		<outlet path="${src-gen}" >
			<postprocessor class="org.openarchitectureware.xpand2.output.JavaBeautifier" />
		</outlet>

	</component>
    
</workflow>

My problem:

7218 INFO  CompositeComponent - Generator: generating 'src::mytemplate::main FOR EPC' => .//gen
7410 ERROR AbstractExpressionsUsingWorkflowComponent - Error in Component  of type org.openarchitectureware.xpand2.Generator: 
	EvaluationException : No Definition 'src::mytemplate::main for autosar403::Autosar' found!
	[23,36] on line 1 'EXPAND src::mytemplate::main FOR EPC'

7410 ERROR WorkflowRunner     - Workflow interrupted. Reason: EvaluationException : No Definition 'src::mytemplate::main for autosar403::Autosar' found!

	No Definition 'src::mytemplate::main for autosar403::Autosar' found! [EXPAND src::mytemplate::main FOR EPC]  in workflow: Generator: generating 'src::mytemplate::main FOR EPC' => .//gen

I think my input at expand tab has problem, but I don't have any ideas to fix it. My model file has 2 parts:
+ BMD: template of parameters
+ EPC: value of parameters
Can you please give a brief direction with this problem?
Thank you

Hi you have to define the entry rule for the root node of your model.
And the paths have to fit: path::file::definition

The qualified value of "expand" must be read as follows: The last segment is the definition within the Xpand file ("main"), obviously correct. The segment before is the name of the template file ("mytemplate" => "mytemplate.xpt"). All segments in front of that are the path to that Xpand file relative to classpath root. And I think here is your problem. I guess that "src" is actually your source folder, and thus the classpath root itself. The template thus lies directly in the classpath root, and the value for "expand" must be "mytemplate::main FOR EPC".

~Karsten

Thanks for all your helps
@Christian Dietrich: How can I define the entry rule for the root node of my model? can you please explain more clearly?
@Karsten Thoms: I changed but it doesn't work, the same issue above

I also try to change classpath in MANIFEST.MF

Bundle-ClassPath: .

with src::mytemplate::main and

Bundle-ClassPath: src/

with mytemplate::main but it doesn't work too

Thanks for your suggest, I try some ways to add <<DEFINE main FOR autosar403::Autosar>> to my xpand code but not effect, it doesn't find 'autosar403::Autosar', I think 'autosar403::Autosar' is just a kind of template for 'main' to follow and it's not in model, and I think I need to connect my model to 'autosar403::Autosar', but I don't know where, sorry because I'm newbie for these, can you give me a more more clearly direction, thanks for your time

Hi Christian, the current metamodel kind of my project is working because I can generate code with it, but oAW doesn't work Sad

, beside when I try to other metamodel kind, I can't generate code anymore, it seem hopeless Sad

Hi,

what do you mean with "i can generate"? i still do not get your point.
the root node of your xml file is an AUTOSAR node and not an BMD root.
so i think you mix up some metalevels here.

so where can i find everything to reproduce the problem.
btw why do you still use good old oaw? and not eclipse xpand.

Hi,
I'm using Artop, that bases on eclipse and work with AUTOSAR model, xpand, and generate code, sorry for missing information. I can normally generate code with my xpand code and arxml model file above on Artop, I want to apply workflow to my project for fast generating code. I found homepage of oaw and install ver 4.3.1 for my Artop, do you mean it's better to use ver 5.x? In my project properties xtend/xpand has
+ ECU Configuration Typesystem (checked)
+ EMF Metamodels (checked)
+ oAW-Classic Metamodel
+ Sphinx-managed EMF Metamodel
+ JavaBean Metamodel
My project also has openArchitectureWare properties with
+ EMF Metamodels (checked)
+ oAW-Classic Metamodel (checked)
+ XSD Metamodels (checked)
+ JavaBeans Metamodel
+ RSA/RSM profiles
+ UML2 profile
By the way, I just install all model plugin on http://download.eclipse.org/releases/indigo
Thanks for your time

Hi I do not know atop but if they come with an own type system you
should maybe use this one instead of xsd. Maybe they do an internal
model2model transformation too. Therefore you should ask the artop
guys what they internally do and which kind of metamodel to use and
how to read the model.

I mean you should use eclipse xpand instead of law xpand.

Hi Christian, thanks for you help I found that they use autosar_4-0-3.xsd to read metamodel and xml.xsd to read model file .arxml, maybe in xtend/xpand properties, I don't have XSD Metamodels so it doesn't work, how can I add it to xtend/xpand properties. Thanks you very much

Hi Christian, I changed to <<DEFINE main FOR autosar403::Autosar>> and workflow worked, but I face other issue that I can't access parameters in my modelwith 'this' pointer, example with «this.Example.parameter.value» it can't see 'Example', I try «this.ARRoot.EPC.Example.parameter.value» but it can't access too, can you give me suggestion?

Maybe I haven't connect right between my model and the file to read the model. Anyway workflow worked, here is my xpand code

«DEFINE main FOR autosar403::Autosar»
«FILE "Hello.h" -»
this = «this»
«ENDFILE»
«ENDDEFINE»

Here is my output

this = org.eclipse.emf.ecore.impl.DynamicEObjectImpl@1e36c93 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@14b93f (name: Autosar) (instanceClassName: null) (abstract: false, interface: false))

My other problem is code completion disappeared, I find solution by check javabean metamodel in xpand/xtend properties but it doesn't work, can you please suggest me some solutions for these issues?
Thanks

Hi,

you have to select XSD Metamodel in the properties.
(you may have to add the xsd to a source folder too)

Hi, I also copy autosar403.xsd and xml.xsd to my source, check XSD metamodel in the project xpand/xtend properties, here is my xpand/xtend properties:
+ECU Configuration Typesystem (checked)
+EMF Metamodels (checked)
+Sphinx-managed EMF metamodels (checked)
+XSD metamodels (checked)
+oAW-Classic Metamodel
+UML2 profiles
+Javabeans Metamodel
Maybe my problem that I have 2 .xsd files to read model file arxml, so the way to access parameters in my model is different from the normal way

Hi Christian,
I think my problem is xsd schema cannot read model, it just see the root one. Follow output of root node above

this = org.eclipse.emf.ecore.impl.DynamicEObjectImpl@1e36c93 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@14b93f (name: Autosar) (instanceClassName: null) (abstract: false, interface: false))

Beside, I find some other schema like autosar40.ecore and autosar40.genmodel, maybe I have to use emf metamodel to load autosar40.ecore and read my model, but my model is xml, so I just don't know to solve this issue.
Thanks

Hi,

i just gave it a try:
the problem is. autosar.xsd has notthing todo with *.arxml

here is what works
(use javabeans metamodel in xpand and required deps to the project.

<workflow>

	<bean class="org.eclipse.emf.mwe.utils.StandaloneSetup" platformUri="..">
		<registerGeneratedEPackage value="autosar40.util.Autosar40Package" />
		<extensionMap>
			<from value="arxml" />
			<to value="autosar40.util.Autosar40ResourceFactoryImpl" />
		</extensionMap>
	</bean>
	
	<component class="org.eclipse.emf.mwe.utils.Reader">
		<modelSlot value="model" />
		<uri value="platform:/resource/test/default.arxml" />
	</component>
	
	
	<component class="org.eclipse.xpand2.Generator">
		<expand value="test::main FOR model" />
		<outlet path="src-gen" />
		<metaModel class="org.eclipse.xtend.type.impl.java.JavaBeansMetaModel" />
	</component>

</workflow>

«DEFINE main FOR autosar40::autosartoplevelstructure::AUTOSAR»
«FILE "test.txt"»
«this»
«ENDFILE»

Hi,
I need generate header .h, and need access parameters in my model, get its value and its name, ex: In my model haves 2 part BMD and EPC, BMD contains definition of 'parameter'(name; type int, enum, string..; range; description), EPC map and set value for it. This model is result when I create by AUTOSAR project in Artop
In my opinion, model is structure of some things insist of its definition and its value and xpand or acceleo is template that can access to these things and organize them follow the way we want(header file, html file ...). Do I misunderstand any important point?

The point you miss is that you have to walk over the model according

Hello Jack

I am also new to Xpand and also needing to generate what you were trying.Did you manage to generate code by accessing the values from .arxml file ? Do you have a more complete project now that you can share ?
