Exception creating bean of class org.dhsinfo. content.AddFileForm: {1}'

What could lead to a run-time error such as:

[ServletException in:/frame/content/content.jsp] Exception creating bean of class org.dhsinfo.content.AddFileForm: {1}'

The strange thing is that the application worked without any problem before. I did not touch anything. I re-ran the application a day later and this problem poped up.

It occurred when I tried to display the content.jsp in the browser window. The content.jsp portion is like:

<html:form enctype="multipart/form-data" action="/content/AddFiles">
        <html-el:select property="document">
          <html-el :-o	 ption value="">-Select-</html-el :-o	 ption>
          <html-el :-o	 ptions collection="PageBeans" property="idAndName" labelProperty="name"/>
        </html-el:select>
        <input type="text" name="linkname" size="60" />
        <html:file property="theFile"/>
        <html:submit>Submit Updates</html:submit>
        <html:reset>Reset Form</html:reset>
</html:form>

The action mapping in the struts-config.xml is like:

    <action
        path="/content/AddFiles"
        type="org.dhsinfo.content.AddFiles"
        name="AddFileForm"
        scope="request"
        validate="false"
        input="/do/ContentMgmt">
       <forward
            name="success"
            path=".file.Confirmation"/>
    </action>

and the form-bean in the struts-config.xml is like:

     <form-bean
        name="AddFileForm"
        type="org.dhsinfo.content.AddFileForm">
     </form-bean>

The AddFileForm.java in the org.dhsinfo.content directory is like:

package org.dhsinfo.content;
 
import javax.servlet.http.HttpServletRequest;
 
import org.apache.struts.action.ActionError;
import org.apache.struts.action.ActionErrors;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.upload.FormFile;
import org.apache.struts.upload.MultipartRequestHandler;
 
public class AddFileForm extends ActionForm
{
   protected String document;
   protected String linkname;
 
   protected FormFile theFile;
 
   public String getDocument()
   {
       return document;
   }
 
    public void setDocument( String document )
    {
        this.document = document;
    }
 
    public String getLinkname()
    {
        return linkname;
    }
 
    public void setLinkname( String linkname )
    {
        this.linkname = linkname;
    }
 
    public FormFile getTheFile()
    {
        return theFile;
    }
 
    public void setTheFile( FormFile theFile )
    {
        this.theFile = theFile;
    }
 
}

I tried the same code another day later. The code worked fine again.

It is really a strange problem. What I am worried about is that I cannot have something that works on day 1, does not work on day 2, and works again on day 3. Who knows what is going to happen on day 4.
