I am developing a module for Alfresco content services community edition version 6.2.0-ga, I can not create nodes by the NodeService, but I can create nodes by RestAPI and Share.
this is my java code trying to use NodeService to create a dummy node :
public EpicDocument upload(EpicDocument doc) {
logger.info("creating new EpicDocument...");
StoreRef storeRef = new StoreRef(StoreRef.PROTOCOL_WORKSPACE, "SpacesStore");
NodeRef root = nodeService.getRootNode(storeRef);
QName type = QName.createQName(EPIC_NAMESPACE_URI, "document");
Map<QName, Serializable> props = new HashMap<>();
props.put(ContentModel.PROP_NAME, doc.getPath());
props.put(QName.createQName(EPIC_NAMESPACE_URI, "fileName"), "FILENAMEEEEEEE132423");
NodeRef nodeRef = nodeService.createNode(root,
ContentModel.ASSOC_CONTAINS,
QName.createQName(NamespaceService.CONTENT_MODEL_1_0_URI, "myNameIsMehrdad"),
type, props).getChildRef();
ContentWriter contentWriter = contentService.getWriter(nodeRef, ContentModel.PROP_CONTENT, true);
contentWriter.setMimetype(MimetypeMap.MIMETYPE_TEXT_PLAIN);
contentWriter.setEncoding("UTF-8");
contentWriter.putContent(new ByteArrayInputStream(doc.getBytes()));
logger.info("EpicDocument created with NodeRef = {}", nodeRef.toString());
return doc;
}
I get the following error :
Caused by: org.alfresco.service.transaction.ReadOnlyServerException: 04100056 Access Denied. The system is currently in read-only mode.

what is the problem? I have no idea, Am I Missing Something?
update: do I need to calls NodeService method in a transaction (like the sample here)?!
the problem was resolved.
as I had guessed, the problem was related to transactions. I was not calling the upload() within a transaction.
now, I call the method inside a transaction by using RetryingTransactionHelper obtained from ServiceRegistry:
NodeRef nodeRef = serviceRegistry.getRetryingTransactionHelper().doInTransaction(
new RetryingTransactionHelper.RetryingTransactionCallback<NodeRef>() {
public NodeRef execute() throws Throwable {
//do work here...
}
}
);
note: do not forget to create the Security Context for the calling thread by using AuthenticationService 's authenticate() method for example.
