Hello,
So I am currently using Struts, including an action that has a fileUpload Interceptor that checks for files that are too large and certain allowable file types. Right now if either of these conditions are met, the system will throw a generic HTTP 500 error up. What I am wondering is how to customize this. in the docs: http://struts.apache.org/2.0.6/struts2-core/apidocs/org/apache/struts2/interceptor/FileUploadInterceptor.html i found these messages that i can supposedly customize. however, the doc does not specify WHERE i am supposed to put these error messages at, and furthermore, after looking at the source code for FileUploadInterceptor, I found that these messages are printed to the log file, and it doesn't look like it prints to the actual HTML. * struts.messages.error.uploading - a general error that occurs when the file could not be uploaded * struts.messages.error.file.too.large - occurs when the uploaded file is too large * struts.messages.error.content.type.not.allowed - occurs when the uploaded file does not match the expected content types specified The doc says that these error messages originate from struts-messages.properties. I'm guessing that's in the struts.jar itself because I don't see it anywhere else, so am I supposed to modify that directly? I'm a little bit iffy about doing that. So, in a nutshell, how do I catch an Interceptor error and make it redirect to a nice page instead of the generic HTTP 500 page? Actually, what would be better is to redirect to an action while passing into it a parameter "message" that will contain error messages. Then, in the JSP i want to do <s:property ...> to grab that message. thank you!
