[lyo-dev] Problems with oslc-java-client 2.0.0
|
Hello!
I am having problems with oslc-java-client in version 2.0.0.
So far I was using OSLC4J 2.0.0 libraries in my implementation and everything worked fine.
Suddenly, when I want to use the client library with one of my providers, I get the following exception.
Full details see at [1].
Exception in thread "AWT-EventQueue-0" java.lang.NoClassDefFoundError: org/eclipse/lyo/oslc4j/core/OslcGlobalNamespaceProvider
I checked out the dependency I am retrieving from https://repo.eclipse.org/content/repositories/lyo-releases/:
<dependency>
<groupId>org.eclipse.lyo.clients</groupId>
<artifactId>oslc-java-client</artifactId>
<version>2.0.0</version>
</dependency>
Internally the oslc-java-client in version 2.0.0 is depending on the following libraries (why in version 2.1.0?):
oslc4j-jena-provider 2.1.0
oslc4j-json4j-provider 2.1.0
In the end it turned out that I am missing oslc4j-core 2.1.0 for jena-provider and json4j-provider in the oslc-java-client.
Is that a correct intended behavior to mix the versions 2.0.0 and 2.1.0?
I end up having version problems because the dependency on oslc4j-core is resolved via
my own other libraries, but in version 2.0.0.
Which implicates Lyo 2.0.0 as such can't be used be used anymore, if you mix providing and client functionality in one application.
Solution was to switch all my implementations to Lyo 2.1.0.
No problems there.
Best regards,
Stefan Paschke
