RE: [Mav-user] Model doesn't get initialized?

2003-02-20 Thread Eelco Hillenius 
If you want to use property test, TestController should have that property:

public class TestController extends ThrowawayBean2
{
  private String name;
  private String test;

  public String getname() { return this.name; }
  public void setname(String s) { this.name = s; }

  public String Perform()
  {
test = blah;
return success;
  }

  public String getTest() { return test };
}

or just try c:out value=${model} / to see if your model was set
properly.

Subject: [Mav-user] Model doesn't get initialized?


Hi there!

I am trying to create a simple example application, using the friendbook as
an example. The framework seems to work fine, including LOG4J. I do have a
lot of problems when I try to get a controller to work. I have something
like this:

package com.maverick.controllers;
import org.infohazard.maverick.ctl.ThrowawayBean2;

public class TestController extends ThrowawayBean2
{
  private String name;

  public String getname() { return this.name; }
  public void setname(String s) { this.name = s; }

  public String Perform()
  {
return success;
  }
}

In the maverick.xml I have something like this:

command name=submitname
  controller class=com.maverick.controllers.TestController /
  view name=success path=testform.jsp/
/command

In my testform.jsp I try to read the value from the model like so:

c:out value=${model.test} /

...and now for the weird part (and also my question)

NOTHING comes out of the model! Am I overseeing something or doing something
wrong?? I spent an entire evening trying to figure out how to get this to
work, no success. I even tried to explicitly fill the model in the
controller using the setModel method nothing happens I have
absolutely no clue ... can anybody help me?

Thanks in advance!

Stephan.

Try setting a breakpoint in:

public void go(ViewContext vctx)  throws IOException, ServletException
{
// Should we put the null in the collection?
if (vctx.getModel() != null)
this.setAttribute(vctx);

// Call the aggregated view now handles the JSP rendering now that

Ok.. I got a bit further now (it actually works) but I am still confused...

I did the following to my example-code:

- Added to the perform method:
this.setName(this.getCtx().getRequest().getParameter(first_name));

Now, I discovered that in my class I actually have a private String Name

From the JSP I can get to the value through c:out value=${model.name}/

RE: [Mav-user] Model doesn't get initialized?

2003-02-20 Thread Schnitzer, Jeff 
Yep, that's exactly right.  The JavaBeans spec says that for a property
nameOfBeer, the setter is:

public void setNameOfBeer(String value)

and the getter is:

public String getNameOfBeer()

The case matters.  However, some templating languages (like Velocity)
will compensate for you (JSTL doesn't).

It gets a little weirder.  If you have a boolean value, say lightBeer,
there are two possible getters:

public boolean getLightBeer()
public boolean isLightBeer()

Since it's possible to have both of those methods on a class, one of
them takes precedence over the other (I don't remember which offhand).

Re: [Mav-user] Model doesn't get initialized?

2003-02-20 Thread Eelco Hillenius 
Stephan,

To be short, the basic idea for JavaBeans is that if you have a property, it
starts with a (usually) private or protected defined field. In order to
grant access on your 'bean' to the outside world, It should have a 'getter'
and/ or a 'setter'; resp. to allow reading and writing of the field. The
standard says that a getter be of form: 'getXxx' where where the Xxx stands
for the name of the property, the first character (right after 'get') being
capitalised. An exception to 'getXxx' is the reading of a boolean value,
which should have the form 'isXxx'. This is the only exception. The setters
take form: 'setXxx'.

As '$model.name' tries to find property name, JSTL will look for the method
.getName() in your class. If it's not there it will fail (I don't know and
actually don't care about the case when your field is declared public).

Read more about it: ftp://ftp.javasoft.com/docs/beans/beans.101.pdf

Another thing to know about Java are the code conventions:

Subject: RE: [Mav-user] Model doesn't get initialized?


 So, if I understand you correctly, I should expect the following
behaviour:

 I have a controller class Foo with a String Name and in a JSP that gets
 activated as a view I have to use $model.name (with lowercase name i.s.o.
 Name as defined in the class) ??

 If the JavaBean specs (which I'm sorry I'm not familiar with) state this
 behaviour as standard I't fine by me. Still, I find it pretty confusing...

 Stephan.

 Also Java seemed to be case sensetive ... :-).

  Do you know about the JavaBean spec? This is pretty standard Java
stuff...

  Ok.. I got a bit further now (it actually works) but I am still
 confused...
 
  I did the following to my example-code:
 
  - Renamed Perform() to perform() (wh!!)
  - Added to the perform method:
  this.setName(this.getCtx().getRequest().getParameter(first_name));
 
  Now, I discovered that in my class I actually have a private String Name
  (mind the capital N!)
 
  From the JSP I can get to the value through c:out
value=${model.name}/
  and NOT through c:out value=${model.Name}/. is that behaviour I
  should expect?
 
  Anyway, it works now and for the time being I'll just keep all my fields
  lowercase to not get mixed up with the $model references from the
 JSP's
 
  Stephan.

  try
  c:out value=${model.name} / in the .jsp file

  Hi there!
 
  I am trying to create a simple example application, using the friendbook
 as
  an example. The framework seems to work fine, including LOG4J. I do have
a
  lot of problems when I try to get a controller to work. I have something
  like this:
 
  package com.maverick.controllers;
  import org.infohazard.maverick.ctl.ThrowawayBean2;
 
  public class TestController extends ThrowawayBean2
  {
private String name;
 
public String getname() { return this.name; }
public void setname(String s) { this.name = s; }
 
public String Perform()
{
  return success;
}
  }
 
  In the maverick.xml I have something like this:
 
  command name=submitname
controller class=com.maverick.controllers.TestController /
view name=success path=testform.jsp/
  /command
 
  In my testform.jsp I try to read the value from the model like so:
 
  c:out value=${model.test} /
 
  ...and now for the weird part (and also my question)
 
  NOTHING comes out of the model! Am I overseeing something or doing
 something
  wrong?? I spent an entire evening trying to figure out how to get this
to
  work, no success. I even tried to explicitly fill the model in the
  controller using the setModel method nothing happens I have
