I'm trying to make a method to delete an entry from a table with Java and jsp , but it's giving 405 error. I'll append the codes.

ProductDao.java:

public void remove(Produto produto) {
    em.getTransaction().begin();
    em.remove(busca(produto));
    em.getTransaction().commit();
}

public Produto busca(Produto produto) {
    return em.find(Produto.class, produto.getId());
}

ProductController.java:

@Delete
public void remove(Produto produto){
    dao.remove(produto);
    result.redirectTo(this).lista();
}

lista.jsp:

<div class="row">
    <form action="<c:url value='/produto/remove'/>" method="DELETE">
        <div class="col s4">
            REMOVER PELO ID:<input type="text" />
        </div>
        <div class="col s4 right">
            <input type="submit" class="btn waves-effect waves-light btn-large right" value="REMOVER"></input>
        </div>
    </form>
</div>

And the error that appears is as follows:

HTTP Status [405] - [Method Not Allowed]

Type Status Report

Description The method received in the request-line is known by the   origin server but not supported by the target resource.

What is the path of the controller? From what I've seen, you have to check if the @Path on the controller is correct and the delete method is correct. Try to use @DELETE, it's easier to read.

The method is right. The error was in the JSP form. The correct one is as follows:

<form action="<c:url value='/produto/remove?id=${produto.id}'/>" method="POST">
        <input type="hidden" name="_method" value="DELETE" />
    <div class="col s4 right">
        <input type="submit" class="btn waves-effect waves-light btn-small right" value="REMOVER"></input>
    </div>
</form>

Then I passed the button next to the line in the table, so it would pick up the automatic id. Later I can make an input text to pass the id to remove, but at first I'll leave it like this.
