JBoss have just released
Seam 3.0.0.Final, which includes Alpha 3 of Seam Forge. So I thought I'd improve my
previous blog entry:
- First, download Seam from here
- Unzip to a folder of your choosing
- Run bin\forge
Type the following commands and press
ENTER after each one. Accept any defaults you are prompted for, and remember to use
TAB and
UP ARROW autocomplete:
new-project --named MyApp --topLevelPackage com.myapp
persistence setup --provider HIBERNATE --container JBOSS_AS6
new-entity --named Person
new-field string --named firstname
new-field string --named surname
new-field int --named age
new-field string --named notes
new-field custom --named homeAddress
[type=The qualified Class to be used as this field's type (of type java.lang.String)]: com.myapp.Address
new-field custom --named workAddress
[type=The qualified Class to be used as this field's type (of type java.lang.String)]: com.myapp.Address
new-entity --named Address
new-field string --named street
new-field string --named suburb
new-field string --named state
new-field string --named postcode
scaffold from-entity com.myapp.domain.Person.java
exit
Next:
- Open Eclipse (with m2eclipse installed)
- Choose File > Import > Existing Maven Projects and import the pom.xml at \seam-3.0.0.Final\forge\MyApp\pom.xml
- Right click the pom.xml and choose Run As > Maven package
- Take the WAR it generates under target/MyApp-1.0.0-SNAPSHOT.war and deploy it under JBoss AS 6.0.0.Final
Open your browser at
http://localhost:8080/MyApp-1.0.0-SNAPSHOT/scaffold/person/list.jsf:
Now, let's play around a bit! These are things that soon Forge will be able to do for you, but for now edit
Person.java and add the lines in bold:
package com.myapp.domain;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Lob;
import javax.persistence.Version;
import org.metawidget.inspector.annotation.UiComesAfter;
import org.metawidget.inspector.annotation.UiSection;
@Entity
public class Person
implements java.io.Serializable {
@Id
private @GeneratedValue( strategy = GenerationType.AUTO )
@Column( name = "id", updatable = false, nullable = false )
long id = 0;
@Version
private @Column( name = "version" )
int version = 0;
public long getId() {
return this.id;
}
public void setId( final long id ) {
this.id = id;
}
public int getVersion() {
return this.version;
}
public void setVersion( final int version ) {
this.version = version;
}
@Column
private String firstname;
public String getFirstname() {
return this.firstname;
}
public void setFirstname( final String firstname ) {
this.firstname = firstname;
}
@Column
private String surname;
@UiComesAfter( "firstname" )
public String getSurname() {
return this.surname;
}
public void setSurname( final String surname ) {
this.surname = surname;
}
@Column
private int age;
@UiComesAfter( "surname" )
public int getAge() {
return this.age;
}
public void setAge( final int age ) {
this.age = age;
}
@Column
private String notes;
@UiComesAfter( "workAddress" )
@Lob
@UiSection( "Other" )
public String getNotes() {
return this.notes;
}
public void setNotes( final String notes ) {
this.notes = notes;
}
@Column
private Address homeAddress = new Address();
@UiComesAfter( "age" )
@UiSection( "Details" )
public Address getHomeAddress() {
return this.homeAddress;
}
public void setHomeAddress( final Address homeAddress ) {
this.homeAddress = homeAddress;
}
@Column
private Address workAddress = new Address();
@UiComesAfter( "homeAddress" )
public Address getWorkAddress() {
return this.workAddress;
}
public void setWorkAddress( final Address workAddress ) {
this.workAddress = workAddress;
}
@Override
public String toString() {
return this.getClass().getSimpleName() + "[" + id + ", " + version + ", " + firstname + ", " + surname + ", " + age + ", " + notes + ", " + homeAddress + ", " + workAddress + "]";
}
}
Similarly for
Address.java:
package com.myapp.domain;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.Version;
import org.metawidget.inspector.annotation.UiComesAfter;
@Entity
public class Address
implements java.io.Serializable {
@Id
private @GeneratedValue( strategy = GenerationType.AUTO )
@Column( name = "id", updatable = false, nullable = false )
long id = 0;
@Version
private @Column( name = "version" )
int version = 0;
public long getId() {
return this.id;
}
public void setId( final long id ) {
this.id = id;
}
public int getVersion() {
return this.version;
}
public void setVersion( final int version ) {
this.version = version;
}
@Column
private String street;
public String getStreet() {
return this.street;
}
public void setStreet( final String street ) {
this.street = street;
}
@Column
private String suburb;
@UiComesAfter( "street" )
public String getSuburb() {
return this.suburb;
}
public void setSuburb( final String suburb ) {
this.suburb = suburb;
}
@Column
private String state;
@UiComesAfter( "suburb" )
public String getState() {
return this.state;
}
public void setState( final String state ) {
this.state = state;
}
@Column
private String postcode;
@UiComesAfter( "state" )
public String getPostcode() {
return this.postcode;
}
public void setPostcode( final String postcode ) {
this.postcode = postcode;
}
}
Then tell
metawidget.xml we'd like to use
RichFaces:
<htmlMetawidget xmlns="java:org.metawidget.faces.component.html">
...
<widgetBuilder>
<compositeWidgetBuilder xmlns="java:org.metawidget.widgetbuilder.composite" config="CompositeWidgetBuilderConfig">
<widgetBuilders>
<array>
<overriddenWidgetBuilder xmlns="java:org.metawidget.faces.component.widgetbuilder"/>
<readOnlyWidgetBuilder xmlns="java:org.metawidget.faces.component.html.widgetbuilder"/>
<richFacesWidgetBuilder xmlns="java:org.metawidget.faces.component.html.widgetbuilder.richfaces"/>
<htmlWidgetBuilder xmlns="java:org.metawidget.faces.component.html.widgetbuilder" config="HtmlWidgetBuilderConfig"/>
</array>
</widgetBuilders>
</compositeWidgetBuilder>
</widgetBuilder>
<layout>
<tabPanelLayoutDecorator xmlns="java:org.metawidget.faces.component.html.layout.richfaces" config="TabPanelLayoutDecoratorConfig">
<layout>
<simpleLayout xmlns="java:org.metawidget.faces.component.layout"/>
</layout>
</tabPanelLayoutDecorator>
</layout>
</htmlMetawidget>
And tell
web.xml the same
(update: this can be done using the richfaces-forge-plugin, see the comments below):
<web-app >
...
<filter>
<display-name>RichFaces Filter</display-name>
<filter-name>richfaces</filter-name>
<filter-class>org.ajax4jsf.Filter</filter-class>
</filter>
<filter-mapping>
<filter-name>richfaces</filter-name>
<servlet-name>Faces Servlet</servlet-name>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>
<servlet>
<servlet-name>Faces Servlet</servlet-name>
<servlet-class>javax.faces.webapp.FacesServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Faces Servlet</servlet-name>
<url-pattern>*.jsf</url-pattern>
</servlet-mapping>
</web-app>
And finally
pom.xml too
(update: this can be done using add-dependency, see the comments below):
<dependencies>
...
<dependency>
<groupId>org.richfaces.ui</groupId>
<artifactId>richfaces-ui</artifactId>
<version>3.3.3.Final</version>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.richfaces.framework</groupId>
<artifactId>richfaces-impl</artifactId>
<version>3.3.3.Final</version>
<scope>compile</scope>
</dependency>
</dependencies>
Then redeploy your app and hit
http://localhost:8080/MyApp-1.0.0-SNAPSHOT/scaffold/person/list.jsf again:
Of course, Seam Forge is still in alpha so not everything works yet. But hopefully this has whetted your appetite for things to come!
Version 1.15 of Metawidget, the Object User Interface Mapping tool (OIM) is now available! This release includes the following enhancements:
The next release of
