Server data in jsp is not displayed properly in table

I have a small program that makes a query to the sql server from which it extracts data, but I can't get it to show me each corresponding data.

The output I get right now is this:

Id Student, Name and phone is fine but the name of the course is the one that I can't make it come out right, the correct output would be:

1. 1, VICTOR, 2212134, FIRST THAT
2. 2, PACO, 984747321, FIRST THAT
3. 3, PEPE, 964321345, SECOND THAT

On the one hand I have a dataStudents.java:

   public class datosAlumnos 
{
Connection miconexion;
String cadsql;

    public datosAlumnos() {
         miconexion=MySQL_Util.Conectar("localhost","root","", "ciclosfp");             
    }
    
    public ResultSet getResultado() {
        
       cadsql ="select a.ID, a.NOMBRE, a.TELEFONO, cursos.NOMBRE from alumnos a, cursos "
               + "where cursos.id = a.CURSO;";
        
        ResultSet rset=
                 MySQL_Util.Sel_Consulta(miconexion, cadsql);
        return rset;
    }
}

And a dataCourses.java:

    public class datosCursos 
{
Connection miconexion;
String cadsql;
private ResultSet rsIDAlum;
private ResultSet rsFCurso;

    public datosCursos() {
         miconexion=MySQL_Util.Conectar("localhost","root","", "ciclosfp");             
    }

       public ResultSet getRsIDAlum() {
        rsIDAlum=MySQL_Util.Sel_Consulta(miconexion, "select * from alumnos");
        return rsIDAlum;
    }

    public void setRsIDAlum(ResultSet rsIDAlum) {
        this.rsIDAlum = rsIDAlum;
    }
    
    
    public ResultSet getRsFCursos() {
        try
        {
        String cadsql2 ="select cursos.nombre from cursos inner join alumnos on cursos.ID=alumnos.ID where alumnos.ID="+rsIDAlum.getString("ID");
            rsFCurso=(MySQL_Util.Sel_Consulta(miconexion, cadsql2));
       
        }
        catch (Exception e)
        {
            rsFCurso=null;
        }
        return rsFCurso;
    }

    public void setRsFCursos(ResultSet rsFCurso) {
        this.rsFCurso = rsFCurso;
    }

}

and the index to display:

    <h1><h:outputText value="Datos de los alumnos:"/></h1>
          
            <h:dataTable border="1" value="#{datosAlumnos.resultado}"
                         var="fila">
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Id Alumno"/>
                    </f:facet>
                    <h:outputText value="#{fila.ID}"/>
                </h:column>  
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Nombre Alumno"/>
                    </f:facet>
                    <h:outputText value="#{fila.NOMBRE}"/>
                </h:column>  
                <h:column>
                    <f:facet name="header">
                        <h:outputText value="Telefono"/>
                    </f:facet>
                    <h:outputText value="#{fila.TELEFONO}"/>
                </h:column> 
                     <h:column>
                    <f:facet name="header" >
                        <h:outputText value="Nombre Curso"/>
                    </f:facet>
                    <h:dataTable value="#{datosCursos.rsFCursos}" var="forma" > 
                        <h:column>
                            <h:outputText value="#{forma.nombre}"/>
                        </h:column>                   
                    </h:dataTable>                            
                </h:column>
            </h:dataTable>
        </body>
    </html>
</f:view>

The thing is that the query of the courses shows the result in the 3 tables of the students and I have tried everything and I cannot make it work. I can't find information on whether aliases can be used in jsp for the tables, since there are two tables that have the same name (name[students] and name[courses]) I can't just put row.name because it takes the name of the students twice.

Update: I have modified the DataCurso.java file since I think this is the correct path but now in Course Name it does not show me any data.
