I,
I make a Web application with Struts.
In the code of the actionBean I use a ArrayList<generic>.MenuAccess menuAccess = new MenuAccess();
ArrayList<MenuAccess> menuArray = new ArrayList<MenuAccess>();
menuArray.add(menuAccess);
session.setAttribute(“menuArray”, menuArray);
@SuppressWarnings(“unchecked”)
ArrayList menuArray2 = (ArrayList<MenuAccess>) session.getAttribute(“menuArray”);
for (int i = 0; i < menuArray2.size(); i++ ) {
menuAccess = null;
menuAccess = (MenuAccess)menuArray2.get(i);
System.out.println(“ArrayList from session : ” + menuAccess.getName() );
}
after the actionBean, it’s ok the results is correct
09:41:12,031 INFO [STDOUT] ArrayList from session : Inscription
09:41:12,031 INFO [STDOUT] ArrayList from session : InscriptionNext i want get the session in the code of the JSP

MenuAccess menuAccess = new MenuAccess();
@SuppressWarnings(“unchecked”)
ArrayList menuArray = new ArrayList<MenuAccess>((ArrayList<MenuAccess>) session.getAttribute(“menuArray”));
for (int i = 0; i < menuArray.size(); i++ ) {
menuAccess = null;
menuAccess = (MenuAccess)menuArray.get(i);
System.out.println(“ArrayList from session : ” + menuAccess.getName() );
}

Hi,
I find the solution,
Because some parameter of the org.apache.jasper.servlet.JspServlet ar initilized for Java 1.4.
You have to change to parameter in the web.xml
<int-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.5</param-value>
</init-param>
<int-param>
<param-name>compilerTargetVM</param-name>
<param-value>1.5</param-value>
<i/nt-param>Edit ${jboss.home}/server/default/deploy/jboss-web.deployer/conf/web.xml
and add the following params to the “jsp” servlet:<init-param>
<param-name>compilerSourceVM</param-name>
<param-value>1.5</param-value>
</init-param>
<init-param>
<param-name>compilerTargetVM</param-name>
<param-value>1.5</param-value>
</init-param>
