When I change in my domain model type Integer to BigInteger, hibernate xdoclet ant task fail with error : (TemplateEngine.invokeMethod 573 ) Invoking method failed: xdoclet.modules.hibernate.HibernateTagsHandler.ifHasCompositeId, line=107 of template file: jar:file:C:\java\projects\excom2lib\xdoclet-1.2\lib\xdoclet-hibernate-module-1.2.jar!/xdoclet/modules/hibernate/resources/hibernate.xdt


If I use f.e. Long instead of Integer, everything works ok (both cases, Integer and Long).

Can you help me anybody?
Thaks in advance.

Please show your class with the XDoclet Tags

package com.domainmodel;

// import packages

import java.math.BigInteger;

/**
* @hibernate.class table="WEEK_NON_WORKING_DAY_TBL"
*/
public class WeekNonWorkingDay implements java.io.Serializable {
public BigInteger weekNonWorkingDayId;
public BigInteger calendarId;
public Calendar calendar;
public BigInteger day;

public void setWeekNonWorkingDayId(BigInteger weekNonWorkingDayId) {
this.weekNonWorkingDayId = weekNonWorkingDayId;
}

/**
* @hibernate.id generator-class="native" length="5"
*/
public BigInteger getWeekNonWorkingDayId() {
return weekNonWorkingDayId;
}

public void setCalendarId(BigInteger calendarId) {
this.calendarId = calendarId;
}

public BigInteger getCalendarId() {
return calendarId;
}

public void setCalendar(Calendar calendar) {
this.calendar = calendar;
}

/**
* @hibernate.many-to-one column="CalendarID" class="com.domainmodel.Calendar"
*/
public Calendar getCalendar() {
return calendar;
}

public void setDay(BigInteger day) {
this.day = day;
}

/**
* @hibernate.property length="1"
*/
public BigInteger getDay() {
return day;
}
public WeekNonWorkingDay() {
super();
}
}

have you tried setting type="java.lang.BigInteger" in your xdoclet tag. However there currently is no builtin Hibernate type which maps to a BigInteger. Are you sure this works out of the Box? Does it work when storing and loading your BigInteger properties?

OK, I fixed this error in XDoclet Hibernate in sources (in class HibernateTagsHandler.java), but problem is also in hibernate (as you said). BigInteger is not supported type.

Question for Gavin: Will be java.lang.BigInteger supported in near future?

Use a custom type

Emmanuel, I am afraid that custom tag will not work with XDoclet hibernate.id in the same way as BigInteger is.


Now I am trying something like this, but it is still not working:

package com.domainmodel;

// import packages

import java.util.Date;
import java.sql.Time;
import java.math.BigDecimal;
import java.math.BigInteger;

/**
* @hibernate.class table="WEEK_NON_WORKING_DAY_TBL"
*/
public class WeekNonWorkingDay implements java.io.Serializable {
public java.math.BigInteger weekNonWorkingDayId;
public java.math.BigInteger day;

public void setWeekNonWorkingDayId(java.math.BigInteger weekNonWorkingDayId) {
this.weekNonWorkingDayId = weekNonWorkingDayId;
}

/**
* @hibernate.id generator-class="native" type="java.lang.Integer"
*/
public java.math.BigInteger getWeekNonWorkingDayId() {
return weekNonWorkingDayId;
}

public void setDay(java.math.BigInteger day) {
this.day = day;
}

/**
* @hibernate.property type="java.lang.Integer"
*
*/
public java.math.BigInteger getDay() {
return day;
}
public WeekNonWorkingDay() {
super();
}
}

I don't get you. I was pointing 5.2.4. Custom value types.

With custom type it works:

public class CustomBigInteger implements UserType {
private static final int[] TYPES = {Types.INTEGER};

public CustomBigInteger() {
}

public int[] sqlTypes() {
return TYPES;
}

public Class returnedClass() {
return java.math.BigInteger.class;
}

public boolean equals(Object o, Object o1) throws HibernateException {
if (o == o1) return true;
if (o == null || o1 == null) return false;
return o.equals(((java.math.BigInteger) o1));
}

public Object nullSafeGet(ResultSet resultSet, String[] strings, Object o) throws HibernateException, SQLException {
Object retO = Hibernate.INTEGER.nullSafeGet(resultSet, strings[0]);
Object bd = null;
if (retO != null) {
bd = new java.math.BigInteger(retO.toString());
}
return bd;
}

public void nullSafeSet(PreparedStatement preparedStatement, Object o, int i) throws HibernateException, SQLException {
String s = null;
if (o != null) {
s = o.toString();
}
Integer intg = new Integer(s);
Hibernate.INTEGER.nullSafeSet(preparedStatement, intg, i);
}

public Object deepCopy(Object o) throws HibernateException {
Object oCpy = null;
if (o != null) {
oCpy = new java.math.BigInteger(o.toString());
}
return oCpy;
}

public boolean isMutable() {
return true;
}
}
