The reason I think its the index is because if I:
1. Load a file in from XML import under /nodeA in workspace 1.
2. Clone nodeA to workspace2
2. Exit my application.
3. Delete nodeA from workspace 1 and 2
4. Reload a file in from XML import.
5. Do a XPATH query for a node in the imported data I get errors.
BUT if I:
1. Load a file in from XML import under /nodeA in workspace 1.
2. Clone nodeA to workspace2
2. Exit my application.
4. Delete the repository home directory manually
3. Delete nodeA from both workspace 1 and 2
4. Reload a file in from XML import.
5. Do a XPATH query for a node in the imported data I do NOTget errors.
Please advise as I my system is to go to production next week and its an
adminable consumer website for a company which expends a fair amount of
traffic on their site.
My code is below. Please let me know if anything looks weird. I have an
object per session that I lock whenever each of these sessions are modified.
The lock object is an instance variable on a singleton.
private void removeTopLevelNode(String name) {
Session prodSession =
JCRConnectionUtil.getInstance().getProductionSession();
Session previewSession =
JCRConnectionUtil.getInstance().getPreviewSession();
Boolean prodLockObject =
JCRConnectionUtil.getInstance().getProductionSessionLock();
Boolean previewLockObj =
JCRConnectionUtil.getInstance().getPreviewSessionLock();
try {
Node previewRoot = previewSession.getRootNode();
Node prodRoot = prodSession.getRootNode();
Node prodNode = null;
if (previewRoot.hasNode(name)) {
synchronized (previewLockObj) {
Node previewNode = previewRoot.getNode(name);
previewRoot.addMixin("mix:lockable");
JCRConnectionUtil.getInstance().savePreviewSession();
if (!previewRoot.isLocked()) {
previewRoot.lock(true, true);
}
previewNode.remove();
JCRConnectionUtil.getInstance().savePreviewSession();
previewRoot.unlock();
}
synchronized (previewLockObj) {
synchronized (prodLockObject) {
if (prodRoot.hasNode(name)) {
prodNode = prodRoot.getNode(name);
prodRoot.addMixin("mix:lockable");
JCRConnectionUtil.getInstance().saveProductionSession();
if (!prodRoot.isLocked()) {
prodRoot.lock(true, true);
}
if (prodRoot.hasNode(name)) {
if (prodRoot.hasNode(name)) {
logger.info("explicitly removing node");
prodNode.update(ConnectionManager.PREVIEW_WORKSPACE);
prodNode.remove();
JCRConnectionUtil.getInstance().saveProductionSession();
prodRoot.unlock();
JCRUtil.getInstance().listChildrenOfRoot(prodSession, "In PROD SESSION");
}
}
}
}
}
