GWT 2.4.0 version incompatibility issues

[krupali raninga]

Hi All,

Currently, i am migrating an application from WAS6.1 to WAS8 and jdk1.5 to jdk1.6. my project uses gwt-user-1.5.3.jar. when i build the project through maven it gives me the error:
[ERROR] Errors in 'jar:file:/C:/Documents%20and%20Settings/rudro_mukherjee/.m
2/repository/com/google/gwt/gwt-user/1.5.3/gwt-user-1.5.3.jar!/com/google/gwt/em
ul/java/util/Vector.java'
[ERROR] Line 119: The type Enumeration is not generic; it cannot be param
eterized with arguments <E>
[ERROR] Errors in 'jar:file:/C:/Documents%20and%20Settings/rudro_mukherjee/.m
2/repository/com/google/gwt/gwt-user/1.5.3/gwt-user-1.5.3.jar!/com/google/gwt/em
ul/java/util/Collections.java'

I changed the version of the jar to gwt-user-2.4.0 which supports generics but still facing the same issue. Can anyone suggest me what am i missing? i am using jdk1.6, WAS8 and RAD8.

Any help/pointers would be appreciated. Thanks in advance.
