I would like to be able to customize the output when an exception is thrown with
minimal or no extra overridden classes. My struts config (1.1) config file looks like
this:
....
<global-exceptions>
<exception
key="error.persistence.create"
type="javax.ejb.CreateException"
path="/tmpl_main.jsp?page=/error/syserror.jsp"></exception>
<exception
key="error.http.methodnotsupported"
type="javax.mail.MethodNotSupportedException"
path="/tmpl_main.jsp?page=/error/syserror.jsp"></exception>
<exception
key="error.naming.namenotfound"
type="javax.naming.NamingException"
path="/tmpl_main.jsp?page=/error/syserror.jsp"></exception>
<exception
key="error.servlet.illegalparameter"
type="com.je.servlet.IllegalParamsException"
path="/tmpl_main.jsp?page=/error/syserror.jsp"></exception>
</global-exceptions>
The properties file looks like this:
errors.header=The following system errors occurred:<ul>
errors.footer=</ul>
error.persistence.create=An error occurred attempting to create a database record
error.http.methodnotsupported=This type of request is not supported for this URL
error.naming.namenotfound=Lookup failed with naming service
error.servlet.illegalparameter=A required field or parameter is missing for the request
The syserror.jsp file is simply:
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<TABLE border="0" cellpadding="5">
<TR>
<TD><html:errors bundle="systemerrorbundle" /></TD>
</TR>
<TR>
<TD></TD>
</TR>
</TABLE>
The above does work. But I only get the properties file message printed. I would
like to do something like this:
error.servlet.illegalparameter=A required field or parameter is missing for the
request {0}
so that I can dynamically generate a message specific to the error. In this case I
want to display whatever field is identified by the exception. So if the exception is
thrown like:
throw new IllegalParamsException("fieldXYZ is missing");
I would like to see "A required field or parameter is missing for the request
'fieldXYZ is missing' "
Can I do this 100% in a declaritive manner? Or how can I pull this off.
thanks
