First of all , I am new to Acceleo and the modeling features of eclipse. What I am trying to do is just to create a simple test file. So for starters, I created a main module:
comment encoding = UTF-8 /]
[module generate('file:/C:/Users/maria/Documents/workspace/org.eclipse.acceleo.module.m2tTransformation/model/PSMMetamodel.ecore')]
[template public generateElement( aServicePSM : ServicePSM)]
[comment #main/]
[file ('test.java', false, 'UTF-8')]
Test
[/file]
[/template]
When i run this I get:
The generation failed to generate any file because there are no model elements that matches at least the type of the first parameter of one of your main templates.
The problem may be caused by a problem with the registration of your metamodel, please see the method named "registerPackages" in the Java launcher of your generator. It could also come from a missing [comment #main/] in the template used as the entry point of the generation.
Also the URI I use is the nsURI attribute value I set to the root of metamodel. I am sure that my input model does contain ServicePSM elements.
What am i doing wrong?
Thanks in advance.
This issue will arise in two cases
You do not have an element of the proper type in your model
The metamodel cannot be resolved
From your message I think we can safely ignore 1. since it seems you have at least one ServicePSM in your model, so we need to address 2.
If you look at your module, you've declared it to generate on metamodel file:/C:/Users/maria/Documents/workspace/org.eclipse.acceleo.module.m2tTransformation/model/PSMMetamodel.ecore. However, EMF rarely, if ever, uses this kind of URIs to refer to its metamodels. If you open your actual model with the text editor (right click > Open With > Text Editor), you can look at the URI that's actually been used to reference the metamodel with the "xmlns" tags at the start.
For example, if I open a model that references OCL elements, I can see xmlns:ocl.ecore="http://www.eclipse.org/ocl/1.1.0/Ecore". You have to make sure you use the same URI in your module file as what you see EMF using in the model file, in this case, it would be http://www.eclipse.org/ocl/1.1.0/Ecore.

I'm trying to create a custom annotation processor that generates code at compilation time (as hibernate-jpamodelgen does). I've looked in the web, and I find custom annotation processors that works with maven, but do nothing when added to the Annotation Processing > Factory Path option. How could I create a processor compatible in this way? I have not found a tutorial that works.
My idea is to, for example, annotate an entity to generate automatically a base DTO, a base mapper, etc that can be extended to use in the final code.
Thank you all
OK, Already found out the problem. The tutorial I hda found out dint't specified that, in order to the compiler to be able to apply the annotation processor, there must be a META-INF/services/javax.annotation.processing.Processor file that contains the qualified class name of the processor (or processors).
I created the file pointing to my processor class, generated the jar and added it to Annotation Processing > Factory Path and all worked correctly.
Just be careful to keep the order of the processors correctly (for example, hibernate model generator claims the classes, so no more generation will be made after it), and change the jar file name each time you want to replace the library (it seems eclipse keeps a cache). These two things have given me a good headache.
Thanks all
I tried to install the EMF plugin inside eclipse but some of the default Ecore diagram and EMF Generator Model projects were not available.
So downloaded a different eclipse installer for modelling i.e. Eclipse Modeling Tools (275 MB ) and found all the relevant model related & diagram based project now.
I have followed the same tutorial http://www.vogella.com/articles/EclipseEMF/article.html .
I was able to create the webpage model diagram & then the webpage.ecore file but then the webpage.genmodel the model generator file was giving errors like the ” names used in the diagrams for the objects are not well formed ” in webpage model diagram .
I googled for these errors which according to me mean that the names are not proper according to the given language for modeling constraints & no resolution to these errors were found.
then tried to ignore the errors and tried Generating the domain classes for java code, java code is generated but then the other following modules Create your model & Edit your model under Run your plugins category does not work further due to the previous errors on this link http://www.vogella.com/articles/EclipseEMF/article.html.
Please help me debug these errors
check if Name property is not null , you need to fill it
http://emftools.tuxfamily.org/wiki/doku.php?id=emfvb:quickstart
You need to set the name of Epackage and also prefix and URI

Does anybody know how to create his own models and controllers in Orchard-based projects? I have an empty project and a pack of screenshots for pages, but I don't know with what to begin. If it is possible, please show an example.
Thanks.
You should start off at the documentation page. There is an 'Extending Orchard' section which walks you through how to create a module, with data access, content parts, and content fields.
Use the command line to generate the module using the code generation module
Documentation here
Then install the Code Generation Extensions from Piotr and follow the instructions on his blog. http://www.szmyd.com.pl/blog/generating-orchard-content-parts-via-command-line
Module adds an Orchard command-line command “codegen part”. It’s
syntax is as follows:
codegen part [/Properties:]
For example:
codegen part Modules.Shop ProductPart /Properties: Name:string,
Price:int
Properties is an optional parameter, so if you’d like to create an
empty part you can just write
codegen part Modules.Shop ProductPart
The command creates a handler, driver, model, record, display and
editor shapes and updates the Placement.info file with default
Content:before placement for your part shape. If you provide
/Properties parameter, the model, record and editor shapes will be
filled with appropriate code accordingly.
I am trying to create Web Services from the Top-Down approach. I downloaded Eclipse and am using the WSDL gui editor in it to build my WSDL files.
I am splitting up my Services based on "modules". The Types I am adding to the WSDLs all need to reference common stuff, such as PersonEntity, AddressEntity, States enumeration (simple type), Countries enumeration (simple type), and AbstractEntity. Since those items are all common I created a seperate WSDL file (named Commons.wsdl) that contains the type information for those types.
I want to "import" that WSDL into my other WSDL files to use:
For example, I have an entity named RegistrationEntity which inherits from AbstractEntity and contains a PersonEntity as well as an AddressEntity. I'm not sure how to do this... I saw that the WSDL spec has "import" and "include" and am not sure which one to use. Also, how do I actually import (or include) the Commons.wsdl file so that I can use the Types defined within it?
Thanks!
Oh, and I'm not sure if I'm supposed to stick this stuff in a seperate WSDL but another type of file such as an xsd or something. I really wanna follow best practices so if that's the proper way to do it then I'd rather do that.
I found out that the problem I had was I was creating a WSDL file for my commons and using an inline scheme for that, rather than creating an XSD file to be imported by my other WSDLs.
So instead I just created an Commons.XSD as my "Common Schema".
I'm trying to run codeanalysis on an assembly that contains an entity model (edmx file). In project properties I have checked the "Suppress results from generated code" option, but I am still getting a lot of CA errors pertaining to the auto-generated EF code.
Has anyone experienced this? And is there a work-around?
Just put the attribute on your class definition.
But how to do it, since your file can get overridden any time. Use a separate file, since all generated classes are partial classes. Open a separate file, and write something like:
[GeneratedCode("EntityModelCodeGenerator", "4.0.0.0")]
public partial class YourEntitiesContextName : ObjectContext
{
}
This will skip code analysis on your particular generated class. StyleCop for instance is more smart and doesn't touch files that have .designer/.generated part in their name or regions that have generated word in their name.
Well, "Suppress results from generated code" really means "Don't look at types with GeneratedCodeAttribute". EF's code generator hasn't added this, historically (though I've suggested it to the team). But you can add it if you use custom T4.
