Errors on saving to JCR

[Clive_Stewart]

In my local jcr I have

content/item

In a bundle I have the following code fragment : On saving or creating nodes I get the following results from the string I created, debugmessage

debugMessage = Server Response = line 127:: got root node doesSpecialsExist it.hasNext() = true line142:: content/specials does exist so specialsRoot = content.getNode("specials"); Just finnished session.save();1 line 127:: got root node doesSpecialsExist it.hasNext() = true line142:: content/specials does exist so specialsRoot = content.getNode("specials"); line 152 :: Inside for (Items item : itemsArrayList) Failed on specialsRoot.addNode Failed to resolve path TimeStamp1417390151359Alla07\12\201 /content/specials line 152 :: Inside for (Items item : itemsArrayList) Failed on specialsRoot.addNode Failed to resolve path TimeStamp1417390151359Alla07\12/specials Just

Looking at your code -- the issue looks like its around naming of the node:

TimeStamp1417390151359Alla07\12\201

In the persisting article - that you based this one:

Persisting CQ data in the Java Content Repository

we named the nodes based on simple string concatenations. For example, firstname, last name, etc. 

We do not use any other chars in the node name.  Try renaming the nodes with simple strings. See:

Thank you,

Your advice was perfect. Thank you for the link about naming.

Best regards
