I'm trying integrate hdiv 2.0.4 with old struts 1.3.8 to maintain old system in security issues. but, when I integrated I got that - hdiv validator in web.xml cannot be cast to servlet filter. Any suggestions for this?
SEVERE: Exception starting filter ValidatorFilter java.lang.ClassCastException: org.hdiv.filter.ValidatorFilter cannot be cast to javax.servlet.Filter at org.apache.catalina.core.ApplicationFilterConfig.getFilter(ApplicationFilterConfig.java:260) at org.apache.catalina.core.ApplicationFilterConfig.(ApplicationFilterConfig.java:107) at org.apache.catalina.core.StandardContext.filterStart(StandardContext.java:4775) at org.apache.catalina.core.StandardContext.startInternal(StandardContext.java:5452) at org.apache.catalina.util.LifecycleBase.start(LifecycleBase.java:150) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1559) at org.apache.catalina.core.ContainerBase$StartChild.call(ContainerBase.java:1549) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745)

It seems you have some classpath problem or duplicated libraries. Similar problem: ClassCastException: MyFilter cannot be cast to javax.servlet.Filter
