Ana Sustic :
I am getting the following error String cannot be cast to javax.jcr.Value when I try to set a properties for the JCR node using the following code.
The javax.jcr.Node.setProperty(String name, Value value) expects value for the "value" parameter but the casting does not work.
// using for-each loop for iteration over Map.entrySet()
for (Entry<String, Object> entry : map.entrySet()) {
try {
//fetch the value of uuid mapped to the key "jcr:uuid"
String uuid= (String) map.get("jcr:uuid");
//get the JCR workspace session value for website
Session session = MgnlContext.getJCRSession(RepositoryConstants.WEBSITE);
//get the JCR node specified by the given identifier
Node node = session.getNodeByIdentifier(uuid);
//verify if the value for the specific value is of type HashMap
//this means we have a nested map which denotes another node
if (entry.getValue() instanceof HashMap ) {
System.out.println("New node: " + entry.getKey());
//Creates a new node at relPath of the specified node type
node.addNode(entry.getKey(),NodeTypes.Page.NAME);
//initializes a new map that points to the nested map
HashMap<String , Object> newmap = (HashMap<String, Object>) entry.getValue();
//recursion happens here
loadMap(newmap);
} else {
//Sets the single-value property for all entries to the specified value.
node.setProperty(entry.getKey(), (Value)entry.getValue()); ---> *error here*
System.out.println("Key = " + entry.getKey() +
", Value = " + entry.getValue());
}
} catch (ItemNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (RepositoryException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Here is the solution thanks to @Ducaz035
String value= (String)entry.getValue();
node.setProperty(entry.getKey(), value);
Ducaz035 :
I believe you can use javax.jcr.Node#setProperty(java.lang.String, java.lang.String) directly. In fact, it accepts String as a value.
The problem in your code is not about String or Value but you try to insert Object, maybe cast Object to String and then set the property
