NoSuchMethodError net.sf.ehcache.Cache.

同事配置Spring security 2，使用Ehcache 缓冲时出现如下错误
Caused by: java.lang.NoSuchMethodError: net.sf.ehcache.Cache.<init>(Ljava/lang/String;ILnet/sf/ehcache/store/MemoryStoreEvictionPolicy;ZLjava/lang/String;ZJJZJLnet/sf/ehcache/event/RegisteredEventListeners;Lnet/sf/ehcache/bootstrap/BootstrapCacheLoader;I)V

Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.userdetails.jdbc.JdbcUserDetailsManager#0.caching': Cannot resolve reference to bean 'userCache' while setting bean property 'userCache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userCache' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Cannot resolve reference to bean 'userEhCache' while setting bean property 'cache'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userEhCache' defined in ServletContext resource [/WEB-INF/spring-security.xml]: Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: net.sf.ehcache.Cache.<init>(Ljava/lang/String;ILnet/sf/ehcache/store/MemoryStoreEvictionPolicy;ZLjava/lang/String;ZJJZJLnet/sf/ehcache/event/RegisteredEventListeners;Lnet/sf/ehcache/bootstrap/BootstrapCacheLoader;I)V
 
原因:使用ehcache-1.3.0.jar或者ehcache-1.5.0.jar替换 ehcache-1.2.3.jar
还需 backport-util-concurrent-3.1.jar
不然会报：java.lang.ClassNotFoundException: edu.emory.mathcs.backport.java.util.concurrent.Exe cutionException
backport-util-concurrent-3.1.jar 下载地址。

StrutsUtils 未定义

同事遇到“StrutsUtils 未定义”错误
struts2.1.6
s:optiontransferselect
没有加载 Struts2 js

已加 <s:head />
源文件生产：
<script src="/xxxx/struts/utils.js" type="text/javascript"></script>

原因：
web.xml中
Struts没拦截js文件,需加如：

<filter-mapping>
 <filter-name>struts2</filter-name>
 <url-pattern>*.js</url-pattern>
</filter-mapping>

JBPM4 4.0 使用问题 -- 2: jbpm 4 在Tomcat 6.0上 运行问题
have different Class objects for the type javax/el/ExpressionFactory used in the signature

使用Tomcat发布时,需将jurl.jar,jurl-engine.jar,jurl-impl.jar替换Tomcat安装目录lib下的el-api.jar
并且项目中不能有这3个包。
Or you can still use Tomcat 6.0, but you must replace el-api.jar with juel.jar. And don't forget to remove juel.jar from your app lib(A duplicate import, ...

JBPM4 4.0 使用问题 -- 1:结合Sqlserver使用问题

惊叹JBPM的更新速度
项目要使用工作流引擎
谈需求时JBPM 4.0还是beta版，现在我们需求谈好，JBPM 4.0也已经出到GA版
JBPM 4与3的差别相当大......，看来JBPM自己已经抛弃了3，我们项目也没必要犹豫了，选4吧~
下载地址：
http://downloads.sourceforge.net/project/jbpm/a%29%20jBPM%204/jbpm-4.0/jbpm-4.0.zip?use_mirror=nchc

1:JBPM 4  DB 里 居然没有 Sql server ，难道不支持Sqlserver。
因为JBPM 4使用Hibernate，不支持Sqlserver可能性不大，所以自己写相应的create.sql drop.sql 及 hibernate配置文件。
测试可以通过。

但还是遇到些许问题..
A：org.hibernate.exception.ConstraintViolationException: could not insert: [org.jbpm.pvm.internal.history.model.HistoryProcessInstanceImpl]
Caused by: java.sql.SQLException: 当 IDENTITY_INSERT 设置为 OFF 时，不能为表 'JBPM4_HIST_PROCINST' 中的标识列插入显式值。
JBPM4_HIST_PROCINST ： DBID_ bigint not null IDENTITY, 改为 DBID_ bigint not null
经查系改Sql时没看仔细,该表非IDENTITY id。

B：org.hibernate.exception.ConstraintViolationException: could not insert: [org.jbpm.pvm.internal.model.ExecutionImpl]
Caused by: java.sql.SQLException: 违反了 UNIQUE KEY 约束 'UQ__JBPM4_EXECUTION__7D8391DF'。不能在对象 'dbo.JBPM4_EXECUTION' 中插入重复键。

ID_ ASC
Note that SQL Server doesn't allow multiple null values in a column with
a unique constraint (JBPM4_EXECUTION.ID_).
忍痛去掉该约束~

2：待续~

RMI其实发布成功了...
为什么开始有错呢？
查看源代码发现：其实是Spring的Debug log
他会先看有没rmi注册

org.springframework.remoting.rmi.RmiServiceExporter.testRegistry(RmiServiceExporter.java:411)
没有log下再
Could not detect RMI registry - creating new one
所以屏蔽该Log4j配置文件中加如：
log4j.logger.org.springframework.remoting.rmi.RmiServiceExporter=INFO

What's new in DWR v3
What's new in DWR version 3
View more presentations from Joe Walker.
在我看来最有用的要属:Reverse ajax 反转Ajax的变更了.
DWR2 时,一般这样使用:
ScriptBuffer script = new ScriptBuffer();
script.appendScript("alert(1)");
ServerContext sctx = ServerContextFactory.get(servletContext ); //FIXME WCTX
if(sctx!=null)
{
 Collection<ScriptSession> pages = sctx.getScriptSessionsByPage("/HustMes/pages/menu/pbsZoneLayoutAction.action");
 );  
 for (ScriptSession session : pages)
 {
  session.addScript(script);
 }
}

并且如果是非页面调用的话 要给类注入 servletContext

现在简单多了,不管页面调用还是其他如WebService调用只需:
String page = ServerContextFactory.get().getContextPath() + "xxx.jsp";
 Browser.withPage(page,new Runnable() {
         public void run() {
      ScriptSessions.addScript("alert(1)");
         }
});
其他方法的使用,请参照API..

Spring Aop 注意...

在使用Spring Aop的时候,有时会拦截不到希望拦截的方法...

有时2.0可以但2.5却不可以~

Spring Aop 代理 有两种:Java动态代理和Cglib代理

一般我用的是Cglib代理..<aop:config proxy-target-class="true">

 

只要在被spring拦截的方法中再调用其他被代理的对象的方法就可以实现嵌套拦截,

如果调用自己对象的方法（包括继承的）,

只是普通对象的方法调用（这时自己是被剥去了代理的壳的原始对象）,

是不能被拦截的。

 

Debug下,看一下是不是proxy的类,被proxy的才有可能被拦截..

 

另外: 使用groovy时,不能对注入groovy Bean的java类进行AOP.(接口编程)

会报以下错误:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'messenger': BeanPostProcessor before instantiation of bean failed; nested exception is org.springframework.aop.framework.AopConfigException: Could not generate CGLIB subclass of class [class $Proxy74]: Common causes of this problem include using a final class or a non-visible class; nested exception is java.lang.IllegalArgumentException: Cannot subclass final class class $Proxy74

 

<lang:groovy id="messenger" refresh-check-delay="5000" script-source="classpath:groovy/Messenger.groovy">
        <lang:property name="message" value="I Can Do The Frug" />
</lang:groovy>


<bean id="testPageAction" class="cn.edu.hust.mes.test.TestPageAction">
  <dwr:remote javascript="test"></dwr:remote>
  <property name="messenger" ref="messenger"></property>

Myeclipse7 安装不上 GroovyEclipse Plugin 原来...

在网上下了 Groovy Eclipse 插件

但怎么都不出来～

Groovy Eclipse 官网显示支持Eclipse3.4

后来发现：

org.testng.eclipse,5.7.0.1,file:/E:\Genuitec\kimplug\GroovyEclipse\plugins\org.testng.eclipse_5.7.0.1\,4,false

 

这句 Myeclipse 自带testing ng......

将这句删掉OK了 ......

好用的工具 nc httpwatch6.0.14

以前使用的Web开发监视工具，

今天要用怎么都找不到了，

只有在网上下了，

这些工具不太好下，一不小心就会中毒

传在空间里备用。

具体使用网上很多不多做介绍了

附上软件及经典使用的Flash视频，Flash可用暴风影音全屏拖动观看
