The solutions to the problem:ClassNotFoundException: org.hibernate.hql.ast.HqlToken

When I run the example provided by the Hibernate 3.1.3 package, "ant eg", I got the error: "ClassNotFoundException: org.hibernate.hql.ast.HqlToken.
The solutions have two which I tried and succeeded.
1: place the antlr-2.7.6rc1.jar into the jdk.xxx/jre/lib/ext directory of jdk package.
2: set the "hibernate.query.factory_class" to "org.hibernate.hql.classic.ClassicQueryTranslatorFactory" in the "hibernate.properties" file.
3: Or add the following sentence into the hibernate.cfg.xml file: org.hibernate.hql.classic.ClassicQueryTranslatorFactory

To run Hibernate example, We must put log4jXXX.jar into the "ext" directory of JDK

To run Hibernate example successfully, We must place log4jXXX.jar into the "jre/ext" directory of JDK (like: JDK1.5.0_06). for example, we can run the example provided by Hibernate package: "ant eg".
otherwise, it will have an error:
java.lang.ExceptionInInitializerError at......
....
Caused by: org.apache.commons.logging.LogConfigurationException: org.apache.commons.logging.LogConfigurationException: No suitable Log constructor

安装struts的注意事项

1：copy "struts.jar" and "servlet-api.jar" to the directory, something like: E:\jdk1.5.0_06\jre\lib\ext. 注意拷到 jre 之下, 其中 servlet-api.jar 是由应用服务器，如tomcat提供的。这样用javac在编译beans才能通过

使用html:link tag 传递带空格的参数所产生的问题

我有上面的语句，其中dishNameForUrl的值带有空格，如：chicken curry .
这时产生的url为: "xxxx/dish.do?dish1=chichen+curry" . 其中空格自动转换成了“+“符号。如果想保留空格，或者成为"xxxx/dish.do?dish1=chichen%20curry" 请问该如何处理？ 我知道用“a href...<%=... %> />“或许能解决这个问题. 但如果只用 html link tag能解决这个问题吗？
