But I followed through this thread of discussion, I just want to let you know that there is a now a better search tool for the technical discussions. Nabble has a large archive of many technical mailing lists, including for example, all Apache lists and Eclipse lists, check out All Apache: http://www.nabble.com/Apache-f90.html Tomcat: http://www.nabble.com/Tomcat-f303.html Eclipse: http://www.nabble.com/Eclipse-f2159.html Unlike a typical mailing list archive such as Gmane or mail-archive, where you can only search one list at a time, Nabble allows you to search all the lists within a project, for example, Tomcat has 2 lists, Eclipse has 30 lists, Apache has 300 lists. You don't have to go to each site to searrch each list, you can simply search from the Nabble software archive: http://www.nabble.com/Software-f94.html - then narrow the result by the projects. You can view the search result in the context of a thread of discussions instead of in an isolated post page. Even if you don't find an answer directly, you could at least find the people who have discussed the issue before, you can then reply or sent private emails to those users and hopefully they will respond like on this list. By the way, Nabble uses Apache Lucene for search, this means you have access to full set of query syntax such as wildcard search, fuzzy search, and grouping of search queries, etc. See this Lucense syntax page: http://lucene.apache.org/java/docs/queryparsersyntax.html You can design and enter a complex query string to pin-point your search on Nabble. In contrast, Google's search has to appeal to the non-technical majorities. -- Sent from the Tomcat - User forum at Nabble.com: http://www.nabble.com/RE%3A-Generic-Types-support-in-Tomcat--t334942.html#a987796

Well, just to clarify, JSPs *can* run Java5 idioms - if you provide Tomcat with a JSP/Java compiler that will undestand them. Servlets are compiled by you and will have no problems running on the desired JVM. OTOH, having Java code in JSPs is evil and should be moved to Servlets or Struts Actions or whatever is the equivalent in Java ServerFaces. JSP are for displaying only. Having said that, I must contradict myself here. I have found that sometimes having a bit of Java code in JSP can clarify things, but it can also bring in a nightmare, especially with JSF. Keep Java code in JSPs to the minimum and if you have to use it, use it for presentation logic only. Business logic should be elsewhere.

To be honest, I never tried it with 5.5.9 I just concluded it from the release notes and other posts on this mailing list. AFAIK, tomcat uses the Eclipse JDT compiler by default to compile JSPs.

Tomcat 5.5.10 has an update JDT compiler from Eclipse 3.1. This understands
Java 5.
You can also configure that you compile with the sun compiler.

Hi All,
Easiest part of this question is simply does tomcat (5.5.7) support
using generic types in JSP files? I searched release notes, FAQ, etc
and found no mention either way. Does some erudite soul have the
answer?
Secondly, if it's supposed to support it, why then would it have
difficulty with the following:
In Part.java (a valid java object, visible from the jsp):
public static ArrayListPart listParts() {/* code */}
In TestPart.jsp (specifically line 4):
% ArrayListPart parts = Part.listParts(); %
Attempting to access TestPart results in:

Generated servlet error:

It's clearly puking on the ObjectName generic type syntax; so, is
it actually supported?

Re: Generic Types support in Tomcat?
Thanks Chuck, I definitely wouldn't have noticed that without the pointer. Oh well, I guess I'll stick to casting and iterators for a few more months ;) On 8/8/05, Caldarale, Charles R [EMAIL PROTECTED] wrote: From: Patrick Thomas [mailto:[EMAIL PROTECTED] Subject: Generic Types support in Tomcat? Easiest part of this question is simply does tomcat (5.5.7) support using generic types in JSP files? Some pertinent paragraphs from: http://jakarta.apache.org/tomcat/tomcat-5.5-doc/jasper-howto.html --- The servlet which implements Jasper is configured using init parameters in your global $CATALINA_BASE/conf/web.xml. # compilerSourceVM - What JDK version are the source files compatible with? (Default JDK 1.4) # compilerTargetVM - What JDK version are the generated files compatible with? (Default JDK 1.4) The Java compiler from Eclipse JDT in included as the default compiler. It is an advanced Java compiler which will load all dependencies from the Tomcat class loader, which will help tremendously when compiling on large installations with tens of JARs. On fast servers, this will allow sub-second recompilation cycles for even large JSP pages. This new compiler will be updated to support the Java 5 syntax as soon as possible. --- I don't know when as soon as possible might be. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
