Louis, I got the following error:
An error occurred between lines: 46 and 47 in the jsp file:
/WEB-INF/jsp/reg/RegForm.jsp
Generated servlet error:
C:\tomcat\work\localhost\test\WEB-INF\jsp\reg\RegForm$jsp.java:263: Method
isReadOnly() not found in class java.lang.Object.
_jspx_th_html_text_1.setReadonly( reg.isReadOnly() );
my code:
<bean:define id="reg" name="reg.form.RegForm" />
<html:html>
...
<html:text property="name" size="40" maxlength="40"
readonly="<%= reg.isReadOnly() %>" />
What is wrong?
