今天我已将我的应用程序从JBOSS 4.2迁移到JBOSS 7.1。服务器已成功启动，没有任何错误消息。但是，当我尝试提交任何表格，其中有＆＃34;日期来自＆＃34;和＆＃34;约会到＆＃34;我收到了这个错误：

org.virc.spack.spring.SpringAccessFilter.doFilter(SpringAccessFilter.java:43)有趣的是，如果我输入＆＃34; 日期来自＆＃34;和＆＃34; 约会＆＃34;字段，例如（2014-05-01和2014-05-05）并提交表单，我不会收到任何错误。但是，如果我将其中一个字段留空（例如，我将＃34; 日期的空字段留给＆＃34;）我得到错误。
在Jboss 4.2版本中，JAVA 1.5 JDK一切运行良好，但在迁移到Jboss 7.1和Java 1.7 JDK后，我遇到了这些错误。有谁知道任何解决方案？
告诉我您是否需要有关使用哪种类型的库等的更多信息。
