Installation

To install these templates into Eclipse/WSAD follow these instructions.
  1. Download the template file and save it in a local directory.
  2. Start Eclipse/WSAD IDE
  3. Select Window/Preferences
  4. Expand Java/Editor/Templates
  5. Click Import
  6. Browse for the downloaded file in step 1 and click OK


Usage
Here is a simple example of how add a couple of Hibernate XDoclet tags to a class file. This will demonstrate how to add a class tag and property tag to a Hibernate class using these templates:

Let's start with a simple class file called Project.
package com.meagle

/**
* This class represents a project
*
* @author MEagle
*/
public class Project {

}
To add the class Xdoclet tags position your cursor inside the class javadoc section and type hib and then press CTRL + SPACE to bring up code completion. Scroll down until you locate hibclass and press the enter key. The more characters that are typed the faster you will code complete. Here is what you will see in the editor:
Notice that the table attribute autopopulated a default table name based on the name of the class. You can accept this entry or override it with your own table name.

Now let's add a property to this class called name. To do this add a new property to the class. Then highlight the field (name) and right click and select 'Source'/'Generate Setter and Getter...'. Then click OK to generate the accessor and mutator methods. Here is what you should see at this point:
package com.meagle

/**
* This class represents a project
*
* @hibernate.class table="Project"
*
* @author MEagle
*/
public class Project {

private String name;
/**
* @return
*/
public String getName() {
return name;
}

/**
* @param string
*/
public void setName(String string) {
name = string;
}
}


Now we need to insert the property tag for the field name. Position your cursor in the javadoc section of getName. Type hibp and press CTRL + SPACE to bring up code completion. Scroll down until you locate hibprop and press the enter key. Here is what you should see now:
package com.meagle

/**
* This class represents a project
*
* @hibernate.class table="Project"
*
* @author MEagle
*/
public class Project {

private String name;

/**
* @return
*/
public String getName() {
return name;
}

/**
* @param string
*/
public void setName(String string) {
name = string;
}
}
Because Eclipse does not provide the return type you will need to manually delete the default @return tag that does not contain the return type. Here is the generated code:
package com.meagle

/**
* This class represents a project
*
* @hibernate.class table="Project"
*
* @author MEagle
*/
public class Project {

private String name;

/**
* @hibernate.property name="getName" column="getName" type="String" not-null="false" unique="false"
*
* @return String
*/
public String getName() {
return name;
}

/**
* @param string
*/
public void setName(String string) {
name = string;
}
}


Unfortunately the Eclipse template builder is not robust enough to get exactly what we need. Notice that the value for the column attribute and the name attribute is 'getName'. Because there is no way to substring this value you will have to manually rename these values to 'name' or another value. I tried to at least populate the attributes as closely as possible. If this is an annoyance you can modify the template(s) to remove this behaviour. Here is what the final code looks like:
package com.meagle

/**
* This class represents a project
*
* @hibernate.class table="Project"
*
* @author MEagle
*/
public class Project {

private String name;

/**
* @hibernate.property name="name" column="Name" type="String" not-null="false" unique="false"
*
* @return String
*/
public String getName() {
return name;
}

/**
* @param string
*/
public void setName(String string) {
name = string;
}
}


From this point you should use Ant and the HibernateDoclet task to generate the Hibernate mapping files from the XDoclet embedded in your .java files.
