This looks wrong to me:
> errors.add("invoerGetal1",new ActionError("inleg moet tussen de 0 en
1.000.000 zijn !"));
You shouldn't pass an error message in the constructor of ActionError, it
should be the key to a message in a resources file.
You obviously have a resources file because the following lines are what are
set up as default for the <form:errors/>
> Validation Error
> You must correct the following error(s) before proceeding:
The resources is specified in the Web.xml file under the "application" key.
<!-- Action Servlet Configuration -->
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>application</param-name>
<param-value>org.apache.struts.example.ApplicationResources</param-value>
</init-param>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<load-on-startup>2</load-on-startup>
</servlet>
So in the example it is: org.apache.struts.example.ApplicationResources
In your checkForm() method you should code something like this:
errors.add("invoerGetal1",new ActionError("error.big.problem"));
Then in the resources file (in WEB-INF/classes/org.apache.struts.example):
error.big.problem=<li>inleg moet tussen de 0 en 1.000.000 zijn !</li>
Note you need the <li>...</li> round the message because the header/footer
entries in the example are set up with <ul>...</ul> tags. So if you don't
put the <li>...</li> round your message they don't appear.
