javax.servlet.jsp.JspException : No getter method available for property 异常

Question

我在 jsp 文件中有这个并且它有效:

<display:column property="certificacion.estado"
                title="CERTIFICACION"
                sortable="true"/>

但我想显示一个 html:像这样选择:

<display:column title="CERTIFICACION"
                sortable="true">
   <html:select property="certificacion.estado" >
      <html:options property="id_estado"
                    labelProperty="estado"
                    collection="listaEstadosCertificacionDTO"/>
   </html:select>
</display:column>

但不起作用，错误说:

No getter method available for property certificacion.estado for bean under name org.apache.struts.taglib.html.BEAN

谢谢!

好的伙计们，我终于可以做到了，就像这样......

<display:column title="CERTIFICACION"  sortable="true">
   <html:select property="certificacion.estado" name="row">
      <html:options property="id_estado"
                    labelProperty="estado"
                    collection="listaEstadosCertificacionDTO"/>
   </html:select>
</display:column>

我添加带有值行的标签名称

"The attribute name of the bean whose properties are consulted to determine which option should be pre-selected when rendering this input field. If not specified, the bean associated with the enclosing tag is utilized. [RT Expr]" look here
