[Simple-support] NoSuchMethodException on deserializing XML

[Wessam A. R. <wes...@gm...>]

Hi,
I get the following exception when i try to deserialize:

java.lang.NoSuchMethodException:
org.netbeans.erdcore.datamodel.database.<init>()
	at java.lang.Class.getConstructor0(Class.java:2706)
	at java.lang.Class.getDeclaredConstructor(Class.java:1985)

	at org.simpleframework.xml.load.Persister.read(Persister.java:279)
	at org.netbeans.erdcore.GraphSceneImpl.Deserialize(GraphSceneImpl.java:248)

any idea what could be causing it not to see the constructor?

Thanks in advance,
