Adding artifacts on ClearCase via Java API

Hi,

I am developing a Java Class to automate the asset creation on RAM, using the Java API. The assets are composed by artifacts that are versioned by ClearCase, so I must pass a reference to the artifacts.

I am having problems running the code, specificially at setReference method. The error generated is the follow: "Method is not executable at the client"

The code I am using is this:
RAMAsset asset = session.createAsset("1.0");
asset.setName("Test 5");
asset.setCommunity(session.getCommunity("MyCommunity"));
asset.setAssetType(session.getAssetType("Design"));
asset.setShortDescription("Test");

ArtifactReference artifactRef= new ArtifactReference();
artifactRef.setKind("CC");
artifactRef.setValue("D:/RAM_view/RAM_VOB/Test/src/Test.java");

File file = new File("D:/RAM_view/RAM_VOB/Test/src/Test.java");
LocalFileArtifact artifact = new LocalFileArtifact(file);
artifact.setReference(artifactRef);

RAMFolderArtifact root = (RAMFolderArtifact)asset.getArtifactsRoot();
root.addArtifact(artifact);

Is that a permission problem at ClearCase? Does anybody know?
