This tutorial learn to you create XML component with XML model. It is able to generate a Java UserBean class with XML mapping Hibernate. Template used has doc parameter type of XML (the Hibernate mapping).
You can find next sample into usecases-catalog/Components/Model/XMLToJavaClass.akgncpt.xml catalog.
With XML mapping Hibernate :
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd" >
<hibernate-mapping>
<class
name="net.sourceforge.akrogen.bean.UserBean"
table="T_USER"
>
<id
name="id"
type="java.lang.Integer"
column="USR_ID_N"
>
<generator class="identity" />
</id>
<property
name="name"
type="java.lang.String"
column="USR_NAME_C"
not-null="true"
length="100"
/>
<property
name="lastName"
type="java.lang.String"
column="USR_LASTNAME_C"
not-null="true"
length="100"
/>
<property
name="birthday"
type="java.util.Date"
column="USR_BIRTHDAY_D"
length="23"
/>
</class>
</hibernate-mapping>
We wish genrate class Java :
package net.sourceforge.akrogen.bean;
public class UserBean {
private java.lang.Integer id;
private java.lang.String name;
private java.lang.String lastName;
private java.util.Date birthday;
public java.lang.Integer getId() {
return this.id;
}
public void setId (java.lang.Integer id) {
this.id = id;
}
public java.lang.String getName() {
return this.name;
}
public void setName (java.lang.String name) {
this.name = name;
}
public java.lang.String getLastName() {
return this.lastName;
}
public void setLastName (java.lang.String lastName) {
this.lastName = lastName;
}
public java.util.Date getBirthday() {
return this.birthday;
}
public void setBirthday (java.util.Date birthday) {
this.birthday = birthday;
}
}
By using this Wizard page :
Steps of this tutorial are :
Here Freemarker template used to generate UserBean Java class :
<#assign classElement = doc["hibernate-mapping"].class />
package ${package};
public class ${className} {
<#list classElement.id as item>
private ${item.@type} ${item.@name};
</#list>
<#list classElement.property as item>
private ${item.@type} ${item.@name};
</#list>
<#list classElement.id as item>
public ${item.@type} get${item.@name?cap_first}() {
return this.${item.@name};
}
public void set${item.@name?cap_first} (${item.@type} ${item.@name}) {
this.${item.@name} = ${item.@name};
}
</#list>
<#list classElement.property as item>
public ${item.@type} get${item.@name?cap_first}() {
return this.${item.@name};
}
public void set${item.@name?cap_first} (${item.@type} ${item.@name}) {
this.${item.@name} = ${item.@name};
}
</#list>
}Template has 3 parameters :
Here XML component which we must use :
<?xml version="1.0" encoding="UTF-8"?>
<component>
<models>
<!-- This component requires selection of XML File which is used into
Template context (Output) -->
<model type="xml" key="doc" useIntoOutput="true" omitDocumentType="true" />
</models>

Here explanation about this XML component :
Model element define model to use into template (useIntoOutput="true"). You can use this model to generate XUL Dynamic Wizard page (with useIntoInput="true").
Here model is file type of type="xml" (Hibernate mapping) which is putted with key key="doc".
omitDocumentType="true" omit document type (DTD, Schema) linked to XML file when this document must be loaded. So you can load it without having DTD,... and without loading it of Internet (the XML loading is optimized in this case).
input/page element describes Wizard page eclipse :
Refresh catalog View. XMLToJavaClass must be appear into catalog.
Double click on XMLToJavaClass component to open Wizard page. This Wizard page is displayed before displaying XML component, because it required XML file (Hibernate mapping) :
Select Hibernate mapping XML file and click on Next button to display XML component Wizard page :
Fill fields of Wizard page :
Click on Finish button. Userbean class is generated into src folder.
Fill Output base dir and Output file name can be given boring when JAVA class is generated :
The next tutorial explains how add scripts in order to manage this problem.
