this part is in servlet
myData is List<String> myData = get the data from java file
then in the servlet i call the code to show the jsp file which has the following code to recieve the data from servlet

this part is in jsp
List<String> myData = request.getAttribute("myData");
Iterator<String> it = myData.iterator();

but jsp page is now shown
gives this error
Type mismatch: cannot convert from Object to List

Tomcat 5.5 ships with and uses it's own compiler (JDT from the Eclipse group). This compiler is not fully 1.5 compliant yet so, even if you're using a Java 1.5 JDK/JRE, JSPs compiled by Tomcat won't understand all of the 1.5 features.

Yet another reason not to put scriptlets in JSPs.
You can write all the Java 1.5 stuff you like in your servlets, beans, and other Java objects with the current version of Tomcat.
