Hello
I have a jsp and a bean :
----------------------------------------------------------------
jsp
----------------------------------------------------------------
<jsp:useBean id ="test" scope="page" class="test_tbe" />
<jsp:setProperty name="test" property="name" param="p_name"/>
<jsp:setProperty name="test" property="email" param="p_email"/>
<jsp:setProperty name="test" property="age" param="p_age"/>
<HTML>
<BODY>
<BR><BR>
Hello
<BR>
please enter your name and your email ...
<FORM METHOD="GET">
Name :
<INPUT TYPE="text" name="p_name">
<BR> Email :
<INPUT TYPE="text" name="p_email">
<BR> Age :
<INPUT TYPE="text" name="p_age">
<BR><BR>
<INPUT TYPE="SUBMIT">
<% if ( request.getParameter( "p_name" ) != null ) { %>
<BR> <BR>
Nom :
<jsp:getProperty name="test" property="name" />
<BR>
Age :
<jsp:getProperty name="test" property="age" />
<% } %>
</FORM>
</BODY>
</HTML>
----------------------------------------------------------------
bean
----------------------------------------------------------------
import java.util.*;
public class test_tbe
{
private String name=null,email=null;
private int age;
public test_tbe()
{
}
public String getName()
{
return email;
}
public int getAge()
{
return age;
}
public void setName(String p_name)
{
name = new String(p_name);
}
public void setEmail(String p_email)
{
email = new String(p_email);
}
public void setAge(int p_age)
{
age = p_age;
}
}
It's work but when I enter a String for the age, its generates an error.
So I change the code in the bean with :
public void setAge(String p_age)
{
try {
age = Integer.parseInt(p_age);
}
catch(Exception e)
{
age=24; // by default
}
}
it seems to be correct but when I try this example, I have this error :
org.apache.jasper.JasperException: Can't find a method to write property
'age' in a bean of type 'test_tbe'
