"No getter method" error

[Dennis Dunn <de...@ppmc.net>]

Hello,

I am working on my first Struts application and  I've run into a problem 
with reading bean properties with the taglibs. I am using the NetBeans 
IDE w/j2sdk 1.4.2 and Struts 1.1.

OK, this is what I see in my browser:

[ServletException in:/tiles/timesheet_viewer.jsp] No getter method for 
property date of bean day'

Here is a chunk of the log file for the Tomcat container:

javax.servlet.jsp.JspException: No getter method for property date of 
bean day
at org.apache.struts.util.RequestUtils.lookup(RequestUtils.java:968)
at org.apache.struts.taglib.bean.WriteTag.doStartTag(WriteTag.java:286)
at 
org.apache.jsp.timesheet_0005fviewer$jsp._jspService(timesheet_0005fviewer$jsp.java:128)
at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:107)
..
..


I've checked the struts-user archives for "no getter method" and a lot 
of those threads were caused by problems with property names and their 
corresponding accessors.  I've double-checked my beans and that doesn't 
seem to be the problem. My getter/setters use the same datatype, I 
reference "date" in the tag and my getter is "getDate()", I haven't 
overridden my accessor methods or provided multiple accessors with 
different signatures....

My next step will be to take a look at RequestUtils.java:968 to see if 
that provides me with a clue as to what I'm doing wrong.


Thanks for your help.

Here is the chunk from the JSP that is using the logic and bean taglibs. 
"week1" is a WeekBean that holds 7 DayBeans.  Each DayBean then has some 
properties that I would like to display:

<logic:iterate name="week1" id="day">
     <tr>
         <td><bean:write name="day" property="date"/></td>
     </tr>
</logic:iterate>

Note that this works fine, the toString() method of the DayBean is 
called and returns the classname:

<logic:iterate name="week1" id="day">
     <tr>
         <td><bean:write name="day"/></td>
     </tr>
</logic:iterate>


Next we've got my beans, I've removed some comments and cruft to make 
this not manageble:

public class DatedTimesheetBean extends Vector {

     /** A string to be used when this bean is displayed. */
     private String date = "";

     /** The total elapsed time (in seconds) of all of the items in this 
bean. */
     private int elapsedSeconds = 0;

     public DatedTimesheetBean() {
     }

     public DatedTimesheetBean(int size) {
         setSize(size);
     }

     public String getDate() {
         return date;
     }

     public void setDate(String d) {
         date = d;
     }

     public int getElapsedSeconds() {
         return elapsedSeconds;
     }

     public void setElapsedSeconds(int s) {
         elapsedSeconds = s;
     }

     public void addElapsedSeconds(int s) {
         elapsedSeconds += s;
     }

     /**
      * Take the elapsed time value (in seconds) and format it
      * for display as HH:MM.
      * @return A String in HH:MM format.
      */
     public String getElapsedTime() {

	<snip>

         return sb.toString();
     }
}


public class WeekBean extends DatedTimesheetBean {

     private static final int SLOTS = 7;

     /** Creates a new instance of WeekBean */
     public WeekBean() {
         super(SLOTS);
         for (int i = 0; i < SLOTS; i++) {
             set(i, new java.util.Vector());
         }
     }

     public void addDay(DayBean day) {
         set(day.getDow(), day);
     }
}


public class DayBean extends DatedTimesheetBean {

     private static final int SLOTS = 8;

     /** The day of the week represented by this DayBean. 0=Sunday, 
6=Saturday */
     private int dow = 0;

     /** Keeps track of the number of slots we have available for events. */
     private int slotCounter = 0;

     /** Creates a new instance of DayBean */
     public DayBean() {
         super(SLOTS);

         for (int i = 0; i < SLOTS; i++) {
             set(i, "00:00");
         }
     }

     /** Set the day-of-week value for this bean. */
     public void setDow(int i) {
         dow = i;
     }

     public int getDow() {
         return dow;
     }

     public String toString() {
         return this.getClass().toString();
     }
}

Re: "No getter method" error [SOLVED]

[Dennis Dunn <de...@ppmc.net>]

Hello,

The tile was choking because I was trying to call a getDate() method of 
a Vector object.  The WeekBean is initialized with Vector()s since I was 
going to iterate throught the contained objects as well as the WeekBean. 
  The first object in the WeekBean was a DayBean but the rest were 
Vectors. When I iterated the WeekBean I was doing OK so lonad a I was 
looking at a DayBean but it choked when I was looking at a Vector.

Challange your assumptions. They are probably wrong.
