I'm looking to write a java program that looks at the asset with the given UID, takes the lastest version, clones it then removes all "Depend on" relationships and all the content and replaces both the given set of "Depend on" and the new content.
4 answers
public static void main(String[] args) {
RAMSession session = new RAMSession("http://localhost:8080/ram.ws", "admin", "admin");
session.setWebServiceTimeout(10000);
// Get an asset with GUID/ latest version
// Assumption here that version is in the form of digit.digit.digit .... else, use search on the GUID
RAMAsset asset = session.getAsset(new AssetIdentification("{0C972087-F35B-2907-8505-8A8EA00EF600}", "*"));
// Create a new version (this asset is duplicated, with a new version)
RAMAsset newVer = session.createAssetNewVersion(asset, "5.0", new RAMStatusMonitor());
// over here you play with the new versioned asset
Relationship[] curRel = newVer.getRelationships();
for (int i = 0; i < curRel.length; i++) {
// remove dependent on relationships
if ("dependency".compareToIgnoreCase(curRel[i].getRelationshipTypeName()) == 0)
newVer.removeRelationship(curRel[i]);
}
// upload/create the new version to the repository
// Make sure to create the asset with its artifacts, before removing things off
session.put(newVer, new NullProgressMonitor());
// Remove artifacts
RAMFolderArtifact top = (RAMFolderArtifact)newVer.getArtifactsRoot();
Artifact[] artifacts = top.getChildren();
// Remove all artifacts from prev. version
for (int i = 0; i < artifacts.length; i++)
top.removeArtifact(artifacts[i]);
// Put new content, relationships, categories ....
// upload/create the new version to the repository
session.put(newVer, new NullProgressMonitor());
session.release();
}

Thank you, Gili. So what was missing is that the new version must be committed before its content can be modified. This overall works now. The only issue I'm having is that the content for the new version comes from a zip file.
// Remove artifacts
RAMFolderArtifact top = (RAMFolderArtifact)newVer.getArtifactsRoot();
Artifact[] artifacts = top.getChildren();
// Remove all artifacts from prev. version
for (int i = 0; i < artifacts.length; i++) {
println artifacts[i]
top.removeArtifact(artifacts[i]);
}
// upload new content
File file = new File(assetContent);
LocalArchiveFolderArtifact artZip = new LocalArchiveFolderArtifact(file);
top.addArtifact(artZip)
This does uploads the content of the zip into the new version of the assets. However, it also creates an empty folder with the same name as the name of the zip file.
Also, while putting the new version, I get the following error:
Exception: com.ibm.ram.common.data.exception.RAMRuntimeException: Unknown exception while submitting asset: Failed to submit asset - Publish Asset Test - ID#F77F4063-132F-6C6F-2405-2A1760D0A1F5 Version#1.0.0.29 - Prefix string too short
Any idea what this means?
Thanks
We'll need the stack trace from the host ramdebug.log for the actual failure.
Richard, how can I get the log to you?
Thanks
All we need is the stack trace that includes the error on the host. So just cut/paste from your ramdebug.log to here in the forum. It shouldn't be too big.
Make sure you get the entire stack trace, including the "Caused by:" traces if any.
// Remove artifacts
RAMFolderArtifact top = (RAMFolderArtifact)newVer.getArtifactsRoot();
Artifact[] artifacts = top.getChildren();
// Remove all artifacts from prev. version
for (int i = 0; i < artifacts.length; i++) {
println artifacts[i]
top.removeArtifact(artifacts[i]);
}
// upload new content
File file = new File(assetContent);
LocalArchiveFolderArtifact artZip = new LocalArchiveFolderArtifact(file);
top.addArtifact(artZip)
This does uploads the content of the zip into the new version of the assets. However, it also creates an empty folder with the same name as the name of the zip file.

I don't think you need to commit it first. You should be able to remove the artifacts BEFORE the initial submit, at the same time you removed the dependencies.
This is actually a bug in the definition. All of the zip contents are supposed to be under that folder that had same name as the zip file. It isn't supposed to be the contents of the zip file under Top folder. I know that would you are expecting makes more sense, but that is not how the code is actually structured. The bug is that it should of put the zip contents under the folder instead of leaving the folder empty.
What we should of have instead of LocalArchiveFikderArtifact is a LocalArchiveArtifact which can then be added to a folder artifact and expanded right there instead.
Since you are already writing this as API, you can just extract the Zip yourself and add the directory structure. .... yes, need more disk space :-( / time, but from code point of view, it is quite small/simple.
Thanks, Gili. I'll try that. In the meantime, as a workaround, I upload the zip and them remove the directory with the same name as the zip file, just clean up. It seems to work.

Interesting. That happens because you have a file that has less than three characters before the '.' (period). We're trying to create a temp file based on this name. I didn't know Java had a restriction that for temp file the part before the '.' needs to be at least three characters.
1) Please open a defect
2) For a workaround, recreate the original asset, and the replacement asset so that there are no file names that have less than 3 characters before the '.'.
