Error generating code from an entity extending Pojo<type>

In the project a Pojo class was created that receives the type of the serializable variable for indexing and treating the convert in a generic way:

Pojo.java:
    {...}
    public abstract class Pojo<T extends Serializable> implements Serializable {
      private static final long serialVersionUID = -519803732136444707L;
      public abstract T getId();          
      public abstract void setId(T id);
    }

When creating a class in the Domain package and extending it, the declaration line looks like this:

Empresa.java:
    {...}
    public class Empresa extends Pojo<Long> implements Serializable{
    {...}

Then we run Nimble for crud generation of the same, I’m using a custom template, based on JSF2(primefaces 3)CRUD. When manipulating the code generation class, groovy shows the following error:

        java.io.FileNotFoundException: C:[...]\src\main\java\br\com\djsystem\

va:43)(continua...)

The same error occurs when I use in my entity a compound attribute whose class also extends the Pojo, under annotations Manytomany, Manytoone etc... In this second case the error occurs in the generation of select / Picklist. I also found that it only occurs when groovy commands are used, as . vm files are normally generated.

Someone who once had this problem could help me find a solution?

Standard class

    @Entity
    @Table(name = "Cliente", uniqueConstraints = {
        @UniqueConstraint(columnNames = {"cnpj"})})
    public class Cliente extends Pojo<Long> implements Serializable {

        private static final long serialVersionUID = 1654193767247607000L;

        @Id
        @Column(name = "id", columnDefinition = "serial")
        @GeneratedValue(strategy = GenerationType.IDENTITY)
        private Long id;

        @Column(name = "razao_social", nullable = false, length = 80)
        private String razaoSocial;

        @Column(name = "cnpj", nullable = false, length = 14)
        private Long cnpj;

        @Column(name = "fantasia", nullable = false, length = 60)
        private String fantasia;

        public Cliente() {
            super();
        }

        public Long getId() {
            return id;
        }

        public void setId(Long id) {
            this.id = id;
        }

        public String getRazaoSocial() {
            return razaoSocial;
        }

        public void setRazaoSocial(String razaoSocial) {
            this.razaoSocial = razaoSocial;
        }

        public Long getCnpj() {
            return cnpj;
        }

        public void setCnpj(Long cnpj) {
            this.cnpj = cnpj;
        }

        public String getFantasia() {
            return fantasia;
        }

        public void setFantasia(String fantasia) {
            this.fantasia = fantasia;
        }

    }

  • Due to the error: java.io.Filenotfoundexception the file was not found. you can post the custom template and the full pojo classes?

  • @Thank you for your reply. The Pojo.java class is as described above, below an example of a class I made, which presents the error, with respect to the custom template the error is reproduced when using the default Demoiselle template(JSF2(primefaces 3)CRUD).

I identified it as a bug of the tool, because of the Generics of the POJO class. If you can register on the project bugtrack we thank you: http://tracker.frameworkdemoiselle.gov.br

Soon a version should be released to contemplate the templates of version 2.5.0 of Demoiselle, and this should be corrected.

  • Thanks for the reply @Saito. and I have registered in the tracker, but I do not have yet permission to post.

  • Michel, Jira has changed the registration policies and so it is always necessary to manually authorize the project. But now we did it. You can check.
