Re: [lyo-dev] Version clash? OslcCoreMissingSetMethodException

Hi Jan-Patrick & all,

 

I have now updated the instructions to create OSLC4j projects for both 2.4.0 (Wink) & 4.0.0-SNAPSHOT (JAX-RS2.0).

https://oslc.github.io/developing-oslc-applications/eclipse_lyo/setup-an-oslc-provider-consumer-application.html

 

While at it, I also migrated the old Bugzilla workshop to https://oslc.github.io/developing-oslc-applications/tutorials.html

It points to two versions of the tutorial: (1) code walkthrough (2) Step-by-step programming instructions

 

Please note that I tested and made sure the Bugzilla adaptor code builds and runs. But I did not test its functionality, since I do not have Bugzilla installed.

If anyone has tips on how we can improve the tutorial, it would be great.

 

Now that the content is under the stable OSLC Developer Guide, we hope we can maintain it better over time.

 

regards

Good morning 

 

And, the latest Lyo Designer 4.0.0-SNAPSHOT will need to be downloaded from the Edge update site http://download.eclipse.org/lyo/p2/edge/

 

I also realise that the instructions on how to setup an oslc4j project are no longer up to date for 4.0.0-snapshot. 

(as presented on http://oslc.github.io/developing-oslc-applications/eclipse_lyo/setup-an-oslc-provider-consumer-application.html)

 

I will update this page early this week. In the meantime, you can look at the sample projects in this repo (https://github.com/OSLC/lyo-adaptor-sample-modelling/tree/4.0.0-snapshot) for tips, in particular the pom.xml file.

 

 

 Regards

Jad

Lyo 4.0.0-SNAPSHOT is available from maven. I have updated the core README: https://github.com/eclipse/lyo.core/blob/master/README.md#getting-started

Dear Jad,


Ok, I digged a little bit into this, and the problem is that the generated code for my DomainModel looks like this:

...

public HashSet<Link> getStars();
public void setStars(final Set<Link> stars );

...

Because the JenaModelHelper looks in the "createPropertyDefinitionToSetMethods" method for the set Method of this Feature like this: 

final Method setMethod = beanClass.getMethod(setMethodName, getMethodReturnType); 


Since "getMethodReturnType" is "HashSet<Link>", but the method is "Set<Link>" it fails. After I manually changed the HashSet<Link> from the get Methods to Set<Link>, everything works again. Of course this is only a temporary hack...

I really would like to use Maven for dependency management, and I was so happy to lyo there! Will this be supported in feature?


Best regards
JPO

Hi Jan-Patrick,
 
before I dig into this problem, any chance you want to work with Lyo 4.0.0-SNAPSHOT instead? Both for LyoDesigner, and the Lyo SDK. 
 
The biggest difference to consider first though is the fact that Lyo 4.0.0-SNAPSHOT uses JAX-RS2.0 (hence you need to adopt an implementation such as Jersey), while 2.4.0 still uses JAX-RS1.0 (and specifically WINK).

Subject: [lyo-dev] Version clash? OslcCoreMissingSetMethodException
 
Dear all,
 
I recently switched to LYO designer 2.4.0. When I access the generated webapp with my client, I get some OslcCoreMissingSetMethodExceptions
(which are somehow hidden and not printed in stacktrace....). I guess that my client does not "understand" the new get Methods. I already found https://github.com/eclipse/lyo.designer/issues/61
 
To what "client" version do I need to switch? My current maven setup is:
        <dependency>
            <groupId>org.eclipse.lyo.oslc4j.core</groupId>
            <artifactId>oslc4j-jena-provider</artifactId>
            <version>${lyo.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-api</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-log4j12</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>xml-apis</groupId>
                    <artifactId>xml-apis</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <dependency>
            <groupId>org.eclipse.lyo.oslc4j.core</groupId>
            <artifactId>oslc4j-json4j-provider</artifactId>
            <version>${lyo.version}</version>
        </dependency>
        <dependency>
            <groupId>org.eclipse.lyo.oslc4j.core</groupId>
            <artifactId>oslc4j-wink</artifactId>
            <version>${lyo.version}</version>
            <exclusions>
                <exclusion>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-api</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
 
(with lyo.version set to 2.4.0, and I also tested 2.2.0).
Both are from the Eclipse Releases repository (https://repo.eclipse.org/content/groups/releases/).
 
 
Best regards
Jan-Patrick
