Hello,
I'm very new to Seam. I Have successfully created sites using JSP and Tomcat
however.
I have seam CR2 deployed with 4.0.5GA using eclipse. I would like to be able to
have a standard java beans created that is used as temporary object in my
application to initialize some entity beans and then commit to the database.
Take for example a very simple UserName and Password combination. My database
password takes a byte[] for the password (sqlserver 2000). I can't change that.
When I generate my entities the User Entity bean has a public void
setPassword(byte[] password) method. Therefore I want a very simple POJO
similar to the Greeter example that is not backed by the DB. I want to create
this object as follows:
package com.foo.web.bean;
|
| import java.io.Serializable;
|
| import org.jboss.seam.annotations.Name;
| import org.jboss.seam.annotations.In;
| import org.jboss.seam.annotations.Out;
|
| @Name("Greeter")
| public class GreeterBean implements Serializable
| {
| /**
| *
| */
| private static final long serialVersionUID = 1L;
| private String name = "";
| private String password = "";
|
| @Out
| public String getName()
| {
| return name;
| }
|
| @Out
| public String getPassword()
| {
| return this.password;
| }
|
| @In
| public void setName(String name)
| {
| this.name = name;
| }
|
| @In
| public void setPassword(String password)
| {
| this.password = password;
| }
| }
|
And then use it in a form as follows:
<div id="sidebar">
| <fieldset>
| <div>
| <h:outputLabel for="name">Login
Name</h:outputLabel>
| <h:inputText id="name"
value="#{Greeter.name}" style="width: 175px;" />
| </div>
| <div>
| <h:outputLabel
for="password">Password</h:outputLabel>
| <h:inputSecret id="password"
value="#{Greeter.password}" style="width: 175px;" />
| </div>
| <div class="errors"><h:messages
globalOnly="true"/></div>
| <div class="buttonBox"><h:commandButton
action="#{Login.login}" value="Account Login" class="button" /></div>
| <div class="notes"><h:commandLink
action="register">Register New User</h:commandLink></div>
| </fieldset>
| </div>
Inside my stateless LoginAction class, I have an @In Greeter variable and I
will use it to extract the bytes from the password to login my user. However,
when I do this I get the following error:
javax.faces.el.EvaluationException: /home.xhtml @25,77 value="#{Greeter.name}":
Exception getting value of property name of base of type :
