Hi the list, First sorry for my last post... It was not the right mailing list. At the end I solved my problem using an Arraylist and making this change :
Index: connectors/util/java/org/apache/tomcat/util/IntrospectionUtils.java =================================================================== --- connectors/util/java/org/apache/tomcat/util/IntrospectionUtils.java (revision 382065) +++ connectors/util/java/org/apache/tomcat/util/IntrospectionUtils.java (working copy) @@ -945,7 +945,8 @@ public static Object convert(String object, Class paramType) { Object result = null; - if ("java.lang.String".equals(paramType.getName())) { + if ("java.lang.String".equals(paramType.getName()) + || "java.lang.Object".equals(paramType.getName())) { result = object; } else if ("java.lang.Integer".equals(paramType.getName()) || "int".equals(paramType.getName())) { It's quite useful. It permit to use the function add from a collection of objects on a text. Without this change, the digester can't convert the String object to an Object and that's why it can't call the add function. I'm not relly sure that I'm sending this patch on the right mailing list... Anyway I got an other doubt. I don't understand why the Loader class (representing the classloader) is on the Wrapper class (representing a servlet) and not on the Context class (representing the web application) in Catalina. Can't it be different between two servlets for the same web application ?
