JBoss 4.0.4GA don't support java 5.0 new features(generics,

[jk88811]

hello, everyone!

I use this code snippet in welcome.jsp

<%
 Iterator<String> categories = faqs.getAllCategories();
 while (categories.hasNext()) {
 String category = categories.next();
 }
%>

I deploy the .ear file to jboss correctly, but my browser display error message as follows.
then I use Tomcat 5.5 to deploy it stand alone, it just work!!

can anybody tells me how to configure jboss? thank you very much!

Error Message:

An error occurred at line: 12 in the jsp file: /welcome.jsp
Generated servlet error:
The type Iterator is not generic; it cannot be parameterized with arguments <String>

An error occurred at line: 12 in the jsp file: /welcome.jsp
Generated servlet error:
Syntax error, parameterized types are only available if source level is 5.0

Hi,

Look in deploy/jbossweb-tomcat55.sar/conf/web.xml from line 224 on and uncomment the following:

<!-- Uncomment to use jdk1.5 features in jsp pages
<init-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.5</param-value>
</init-param>
-->

I hope that helps.

Thank you, peter!

I carry out what you say, and now everything is good!

thanks again

Is it possible to configure the compilerSourceVM via an application-specific deployment descriptor (something like WEB-INF/tomcat.xml or WEB-INF/jboss.xml? ) rather than the global jboss configuration? I'd like to bundle this setting into my WAR to reduce the workload on the downstream sysadmins who install it. Ideally, this would be in a jboss-specific xml file so that I can bundle jboss config into the WAR without tying the WAR to be JBoss specific.

Thanks!
