Have you tried using a Vector as a parameter instead? In the book ADVENCED JAVA SERVER PAGES by David M Geary, there are good examples, but don't have the time right now to look for one.
Sorry. -----Mensagem original----- De: cbarnes [mailto:[EMAIL PROTECTED]] Enviada em: quinta-feira, 21 de março de 2002 09:13 Para: [EMAIL PROTECTED] Assunto: attributes for custom tags I am writing a custom tag where one of the attributes required is a String array. I know I'm being awkward but I want to be able to create this string array within the custom tag line. I imagined that I would be able to do something like the following <prefix:mytag myattribute="<%= new String[] {item1, item2, item3} %>" /> However, tomcat wants to translate the type into something.class, but gets muddled up because of the []. I then thought I could change the String array into a String of comma separated items, and allow the custom tag to convert this into a string array using a StringTokenizer. However, the problem here is that each of the items in the list is an expression. I had imagined that if I did something like the following <prefix:mytag myattribute="<%= item1 %>, <%= item2 %>, <%= item3 %>" /> that each expression would be evaluated. But it doesn't. It recognises the first <%= and the last %> and tries to evaluate everything in between as one expression. If I change it to <prefix:mytag myattribute="<%= item1, item2, item3 %>" /> the expressions don't get evaluated and it doesn't consider it as one quoted string anyway. Can anyone suggest how to get either of these 2 approaches to work, or suggest a different approach to set a custom tag attribute that is a list of expressions?
