Persistence data

Former Member · ‎11-16-2006

Hi,

We are developping a persistent application.

The code of our PersistenceMaster is:

We have got two class to store in persistence:

1. MaestroPersistencia.java (is our Persistence Master)

2. MetodosPersistencia.java (is the class with the write/read methods)

The code is:

1. MaestroPersistencia.java

class MaestroPersistencia implements PackagePersistenceMaster, EntityFactory {

static DescriptorRuntime PDR = DescriptorRuntime.getInstance();

static String[] CLASSTYPES = new String[] { Material.CLASSTYPE};

static AttributeDescriptor[] MATERIAL_ATRIBUTOS ;

static LinkDescriptor[] NO_LINK = new LinkDescriptor[] {};

static ClassDescriptor P_CLASS_MATERIAL;

static {

try {

MATERIAL_ATRIBUTOS = new AttributeDescriptor[] {

PDR.createAttributeDescriptor("mat",AttributeType.STRING,1,30) ,

PDR.createAttributeDescriptor("descripcion",AttributeType.STRING,1,40)

};

P_CLASS_MATERIAL = PDR.createClassDescriptor(Material.CLASSTYPE,MATERIAL_ATRIBUTOS);

} catch (Throwable t) {

t.printStackTrace();

System.exit(-1);

}// fin del catch

}// fin de static

MaestroPersistencia() {

}

public String getPackageName() {

return null;

}

public String[] getClasstypes() {

return CLASSTYPES;

}

public PersistableEntity createEntity(PersistenceContainer obj) {

return new Material(obj);

}

public ClassDescriptor getClassDescriptor(String classtype) {

}

public PackagePersistenceMaster getPersistenceMaster() {

return this;

}

2. MetodosPersistencia.java

public class MetodoPersistencia {

private static PersistenceRuntime persistence;

private static PersistenceManager perManager;

private static MaestroPersistencia master;

private static int idCount;

public static void setupPersistenceRuntime()

{

try {

persistence = PersistenceRuntime.getInstance();

master = new MaestroPersistencia();

persistence.registerPersistenceMaster(master);

perManager = persistence.getPersistenceManager(VisibilityType.SEPARATED);

perManager.registerEntityFactory(master);

perManager.beginTransaction(true);

} catch (Exception e) {

e.printStackTrace();

System.out.println("Error during startup");

System.exit(-1);

}

public static void writeEntity(PersistableEntity obj)

{

PersistenceException e = null;

try {

perManager.update(obj, TreeOptionType.SKELETON);

)catch (PersistenceException e1)

e = e1;

e1.printStackTrace();

}

public static void addEntity(String material, String descripcion)

{

PersistableEntity emat = null;

if (material.length() > 0)

{

emat = createMaterialEntity(Integer.toString(idCount));

idCount++;

}

setMaterialAtributos(emat,material,descripcion);

writeEntity(emat);

}

public static PersistableEntity createMaterialEntity(String mat)

{

PersistableEntity material = new

Material(perManager.getPersistedObjectFactory().createPersistedObject(MaestroPersistencia.P_CLASS_MATERIAL, mat));

return material;

}

public static void setMaterialAtributos(PersistableEntity material,String mate, String descripcion){

Material mat = (Material) material;

mat.setValues(mate,descripcion);

}

The problem is that when we call this instruction:

MetodosPersistencia.setupPersistenceRuntime();

MetodosPersistencia.addEntity("example","this is one example");

Throws this exception:
