Re: [email] Dynamic attachments in mailer taglib 2 using JavaBean
That's what I can't understand. Should my call to the bean be a valid
non-static code to get that value? I am new to java javabeans. The
statement you wrote is exactly my statement in the JSP:
yourbeanname.getTempFilePath()
Is the same as:
RadTicketsFileDownloadForEmailAttachmentBean.getTempFilePath()
How else do I make this statement in a non-static way?

Re: [email] Dynamic attachments in mailer taglib 2 using JavaBean
No Ferindo. What he's saying is you are calling the class not an instance of
the class.
You can only call a class if the method is stactic.

[email] Dynamic attachments in mailer taglib 2 using JavaBean
I've written a javabean that connects to a database, downloads a file,
and one of the getter methods returns the complete file path to the
file.
The problem I have is: when the JSP runs and gets to the part where it
gets the file path to pass to the taglib, I get an error message that
is typical of a reference to a nonstatic variable. This concerns me as
I thout getter methods in javabeans would inherently returns values
