参数传递问题
我想通过以下语句传递一个参数到一个Action中，并在Action中得到它，但是遇到了问题，让我不知怎么办，很郁闷啊！<html:link action="/deleteforumAction.do?postTime=<%=ff.getPostTime() %>">删除</html:link>
通过以下语句得到参数，但得到的是个空值还抛出了异常：
String postTime=request.getParameter("postTime");
错误提示：
2008-4-17 8:19:54 org.apache.tomcat.util.http.Parameters processParameters
警告: Parameters: Character decoding failed. Parameter skipped.
