Could not determine type for: java.util.Set, at table:

Front-end
#1

Olá pessoal,

Estou há varios dias tentando a solução para meu problema e gostaria da ajuda de todos vocês.
Tenho estudado java pelo livro Java para a web e estou no capítulo 6, aplicando segurança ao sistema (Spring Security) e me deu com um erro no console do Tomcat.

Erro do console Tomcat:

A tabela usuario_permissao deveria ter sido criada no banco mas ele não determina tipo da coluna permissao.
Parte do código da classe Usuario.java:

@ElementCollection(targetClass = String.class)
	@JoinTable(
			name = "usuario_permissao",
			uniqueConstraints = {@UniqueConstraint(columnNames = {"usuario","permissao"})},
			joinColumns = @JoinColumn(name = "usuario"))
			@Column(name = "permissao",length=50)
	private Set<String> permissao = new HashSet<String>();

Oi amigos,

O problema foi resolvido através da atualização das lib’s e que provavelmente havia alguma delas corronpidas.

Valeu pela ajuda!
