java.lang.IllegalAccessError - Hibernate2.1 final

Ricardo · **Posted:** Fri Dec 12, 2003 2:15 pm

I downloaded Hibernate2.1 final.

When I add the UsuarioRegraVO.class in the Configuration the following exception is being thrown!
java.lang.IllegalAccessError

cfg.addClass(UsuarioRegraVO.class);
where UsuarioRegraVO has a composite-id

what's the problem?

thanks :-)

Ricardo,

Can you post your code, and your mapping? It would make things a bit more easier ;-)

I have 25 mapping files, but the error only occurs with this:

The application was working fine with the Hibernate 2.0.1, and when I updated to 2.1 final, that error occurred.

thanks

Ok,

Can you also post the VO, and the PK classes as well?

I generated the code with the Hibernate CodeGenerator..

Code:

package net.wasys.crea.model;

import java.io.Serializable;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;

/** @author Hibernate CodeGenerator */
public class UsuarioRegraVO implements Serializable {

    /** identifier field */
    private net.wasys.crea.model.UsuarioRegraPK id;

    /** full constructor */
    public UsuarioRegraVO(net.wasys.crea.model.UsuarioRegraPK id) {
        this.id = id;
    }

    /** default constructor */
    public UsuarioRegraVO() {
    }

    public net.wasys.crea.model.UsuarioRegraPK getId() {
        return this.id;
    }

    public void setId(net.wasys.crea.model.UsuarioRegraPK id) {
        this.id = id;
    }

    public String toString() {
        return new ToStringBuilder(this)
            .append("id", getId())
            .toString();
    }

    public boolean equals(Object other) {
        if ( !(other instanceof UsuarioRegraVO) ) return false;
        UsuarioRegraVO castOther = (UsuarioRegraVO) other;
        return new EqualsBuilder()
            .append(this.getId(), castOther.getId())
            .isEquals();
    }

    public int hashCode() {
        return new HashCodeBuilder()
            .append(getId())
            .toHashCode();
    }

}

Code:

package net.wasys.crea.model;

import java.io.Serializable;
import org.apache.commons.lang.builder.EqualsBuilder;
import org.apache.commons.lang.builder.HashCodeBuilder;
import org.apache.commons.lang.builder.ToStringBuilder;

/** @author Hibernate CodeGenerator */
public class UsuarioRegraPK implements Serializable {

    /** identifier field */
    private String usuario;

    /** identifier field */
    private String tiporegra;

    /** full constructor */
    public UsuarioRegraPK(java.lang.String usuario, java.lang.String tiporegra) {
        this.usuario = usuario;
        this.tiporegra = tiporegra;
    }

    /** default constructor */
    public UsuarioRegraPK() {
    }

    public java.lang.String getUsuario() {
        return this.usuario;
    }

    public void setUsuario(java.lang.String usuario) {
        this.usuario = usuario;
    }

    public java.lang.String getTiporegra() {
        return this.tiporegra;
    }

    public void setTiporegra(java.lang.String tiporegra) {
        this.tiporegra = tiporegra;
    }

    public String toString() {
        return new ToStringBuilder(this)
            .append("usuario", getUsuario())
            .append("tiporegra", getTiporegra())
            .toString();
    }

    public boolean equals(Object other) {
        if ( !(other instanceof UsuarioRegraPK) ) return false;
        UsuarioRegraPK castOther = (UsuarioRegraPK) other;
        return new EqualsBuilder()
            .append(this.getUsuario(), castOther.getUsuario())
            .append(this.getTiporegra(), castOther.getTiporegra())
            .isEquals();
    }

    public int hashCode() {
        return new HashCodeBuilder()
            .append(getUsuario())
            .append(getTiporegra())
            .toHashCode();
    }

}

To me, exception stack trace would be helpful.

Take a look at the FAQ, at first glance your problem looks very popular http://www.hibernate.org/74.html#A3
