[john von]

could it be something as simple as file permissions?

[john von]

You think so?
In the book, it uses Struts1.1 but what i have is Struts2.2. I couldn't find in jakarta site of the older version. I couldn't move on in my study because of these errors.

Anymore help who had this book?

Thanks!

Hi,

I found this list of common struts errors. It contains an error similar to the one you are getting.

Looks like SearchForm does not extend ActionForm
OR
the form bean entry in struts-config.xml for search form is using ActionForm instead of SearchForm.

Thanks for the link but i still couldn't find an answer. Ive checked the 2 probable cause you mentioned but they're set as right.

Anybody?

Try enabling logging.

Got this from the struts site.

The simplest way to enable logging is to create two files in WEB-INF/classes:
commons-logging.properties
org.apache.commons.logging.Log=org.apache.commons.logging.impl.SimpleLog
simplelog.properties
# Logging detail level,
# Must be one of ("trace", "debug", "info", "warn", "error", or "fatal").
org.apache.commons.logging.simplelog.defaultlog=trace

You should now be able to see trace statements on your server console. This might help in debugging. Post the ones just before the stack trace for us to have a look.

[Edit] The error seems to be generated from the <html:form> tag in search.jsp
