有个人对James .领导的JSR-99.groovy Language specification
进展缓慢非常不满.要求James改进工作方法,并寻找熟悉语言规范文档规范的助手来做.
并对Groovy语言目前竟然没有完全的语言手册大大不满.

JBOSS JAAS 403错误解决问题.
问题描述:
当使用JAAS Login成功后,访问任何页面出现:
HTTP Status 403 - Access to the requested resource has been denied
错误
分析:
当使用JAAS login的时候.在login jsp里包括如下Form:
在conf/login-config.xml包含如下:
<application-policy name = "Demo">
<authentication>
<login-module code = "org.jboss.security.auth.spi.DatabaseServerLoginModule"
flag = "required">
<module-option name = "dsJndiName">java:/MySqlDS</module-option>

</module-option>
<module-option name = "rolesQuery">
Select roleid,roleid as Role from sys_L_UserRole where userid =?
</module-option>
</login-module>
</authentication>
</application-policy>

JBOSS JMX FAQ 1
1.Q:如何给我写的Servlet添加一个JMX的监控组件呢?
A: 在Servlet init() 方法中调用MBeanServer.registerMBean(...)
来注册你的servlet
Code Example:
List srvrlist = MBeanServerFactory.findMBeanServer(null);
MBeanServer server = (MBeanServer)srvrlist.iterator().next();
ObjectName name = new ObjectName("com.wxk:service=mybean");
Mybean emb = new Mybean();
server.registerMBean(emb, name);
2.Q:为什么我发布的sar总是扔出:Class does not expose a management interface :错误:
A:JBoss规则或JMX规范:一个Class的JMX Management Interfact必须是添加后缀MBean
比如你的Class为 x.y那么对应的JMX管理接口的class名字必须为x.yMBean
3.Q:如何得到当前系统的默认MBeanServer?
A:使用MBeanServerFactory.findMBeanServer(null).iterator().next();
要注意必须使用同一个VM/ClassLoader.

WindowSXP 批文件新增强大功能.
SET 变量字符串替换:
/P 命令行开关允许将变量数值设成用户输入的一行输入。读取输入
行之前，显示指定的 promptString。promptString 可以是空的。
环境变量替换已如下增强:
%PATH:str1=str2%
会扩展 PATH 环境变量，用 "str2" 代替扩展结果中的每个 "str1"。
要有效地从扩展结果中删除所有的 "str1"，"str2" 可以是空的。
"str1" 可以以星号打头；在这种情况下，"str1" 会从扩展结果的
开始到 str1 剩余部分第一次出现的地方，都一直保持相配。
也可以为扩展名指定子字符串。
%PATH:~10,5%
会扩展 PATH 环境变量，然后只使用在扩展结果中从第 11 个(偏
移量 10)字符开始的五个字符。如果没有指定长度，则采用默认
值，即变量数值的余数。如果两个数字(偏移量和长度)都是负数，
使用的数字则是环境变量数值长度加上指定的偏移量或长度。
%PATH:~-10%
会提取 PATH 变量的最后十个字符。
%PATH:~0,-2%
会提取 PATH 变量的所有字符，除了最后两个。
set DT=%DATE%_%TIME%
echo %DT%
set DT=%DT: =%
echo %DT%
set DT=%DT:/=-%
echo %DT%
set DT=%DT::=-%
echo %DT%
set DT=%DT:~4%
echo %DT%
set DT=%DT:~0,-3%

J2SE 5.0 New Features.
J2SE 5.0新操作符含义
1. Generics(泛型)
,读做:” of Type”,比如Collection c读做”Collectioin of String c
2. for-loop:
Colon( : ) 冒号,读做: for each typeObject t in c.”
比如:
for (TimerTask t : c) 读做: for each TimerTask t in c
3. varargs(变元),声明参数个数不确定的方法或接口.
三个点(…)；
public static String format(String pattern,Object... arguments);
public static String format(String pattern,Object... arguments)
{
String temp="";
for(Object t:arguments)temp+=t;
return pattern+":"+temp;
}
4. enum 枚举声明
简单enum:
enum Season { WINTER, SPRING, SUMMER, FALL }
Examples:
//Test for enum simple
for (Season rank : Season.values())System.out.println("Enum:"+rank);
复杂enum:
可以包含数据,行为
public enum Planet {
MERCURY (3.303e+23, 2.4397e6),
VENUS (4.869e+24, 6.0518e6),
EARTH (5.976e+24, 6.37814e6),
MARS (6.421e+23, 3.3972e6),
JUPITER (1.9e+27, 7.1492e7),
SATURN (5.688e+26, 6.0268e7),
URANUS (8.686e+25, 2.5559e7),
NEPTUNE (1.024e+26, 2.4746e7),
PLUTO (1.27e+22, 1.137e6);
private final double mass; // in kilograms
private final double radius; // in meters
Planet(double mass, double radius) {
this.mass = mass;
this.radius = radius;
}
private double mass() { return mass; }
private double radius() { return radius; }
// universal gravitational constant (m3 kg-1 s-2)
public static final double G = 6.67300E-11;
double surfaceGravity() {
return G * mass / (radius * radius);
}
double surfaceWeight(double otherMass) {
return otherMass * surfaceGravity();
}
}
Example:
//Test for complex enum Planet
for (Planet p : Planet.values())
System.out.printf("Your weight on %s is %f%n",
p, p.surfaceWeight(8));

ERM BOM
物料清单(BOM)，又称为产品结构表或产品结构树；在某些工业领域，可能称为“配方”、“要素表”或其它名称。在ERP系统中，物料一词有着广泛的含义，它是所有产品、半成品、在制品、原材料、配套件、协作件、易耗品等等与生产有关的物料的统称。BOM作用于计算机识别物料、接受客户定单、编制计划、配套（装配）和领料、加工过程跟踪、采购和外协、成本计算、报价参考、物料追溯、改进产品设计等等。系统可以采用多种方法描述物料清单，如单层法、缩进法、模块法、暂停法、矩阵法以及成本法等等。
BOM（Bill of material ）物料清单；
PP（Production Planning）生产计划大纲；
MPS（Master Production Scheduling）主生产计划；
RCCP( Rough Cut Capacity Planning）粗能力需求计划；
MRP(Materiel Requirements Planning) 物料需求计划；
CRP(Capacity Requirements Planning) 能力需求计划；
PAC(Production Activity Control) 车间作业管理；
IM(Inventory Management) 库存管理；

如何用Linux下Sendmail把所有的近来的Email全部转发到另外一个Sendmail Server上呢?
这种模式叫做:smart Host模式.
在/etc/sendmail.cf里,找到DS关键词.
在后面加入你要转发到的Senmail server的名字
必须是名字,如果用IP可能不能成功.同sendmail版本有关.
1.在/etc/hosts加入一行
10.2.5.1 MailGW
2.在/etc/sendmail.cf里加入
# "Smart" relay host (may be null)
DSMailGW
就可以了.然后可以用.
mail -v 来跟踪一下发送过程

问题:为什么Linux启动的时候在Sendmail就停在那里,非常慢?
原因:可能的原因是修改了网卡IP.
你必须在/etc/hosts
把localhost加在IP不是127.0.0.1的那行
如下:
10.2.5.240 localhost SZSE199

JBOSS如何在Web加如虚拟目录
I made the following changes. Not all of them may be required. You can try one at a time.
1. jboss/server/default/conf/jboss-service.xml
Code:
<server>
<!-- Load all jars from the JBOSS_DIST/server/<config>/lib directory. This
can be restricted to specific jars by specifying them in the archives
attribute.
-->
<classpath codebase="lib" archives="*"/>
<!-- Set the virtual directory to be used by the application

JbuilderX如何把任意类型的文件都打包到War或Jar里?
以Jbuildx为列
1.选择Tools/Prefefences/Browser..File Types
2,选则Module的老鼠右键选择properties..
入图:
3.还有一种最简洁的方法,假如Filters
加入Include型的Filter,Module的老鼠右键选择properties/Content/Filter,加入*.*类型的过滤.

如何用XML-RPC来传递汉字参数.
我这里使用的是xml.apache.org的实现.
关键的一点:改变字符集合可以使用:org.apache.xmlrpc.XmlRpc.setEncoding("UTF-8");
这会影响对传递的数据的encode.
下面用一个简单的Client/Server/Handler来说明XML-RPC的实现:
package home.wxk;
import org.apache.xmlrpc.*;
import java.util.Vector;
public class RpcClient {
public RpcClient() {
}
public static void main(String[] args) throws Exception
{
//org.apache.xmlrpc.XmlRpc.setEncoding("UTF-8");
XmlRpcClient xmlrpc = new XmlRpcClient ("http://localhost:8080");
Vector params = new Vector ();
// params.addElement (new String(" 123".getBytes(),"UTF-8"));
params.addElement(new String("这时候汉字的未来xmlrpc123".getBytes(),"ISO-8859-1"));
// this method returns a string
String a="";
// try
// {
a=(String)xmlrpc.execute("hello.sayHello", params);
System.out.println("........"+a);
// }catch(Exception e)
// {
// System.out.println("异常：......."+a);
// }
}
}
package home.wxk;
import org.apache.xmlrpc.*;
public class RpcServer {
public static void initServer() {
// XmlRpc.setDriver("org.apache.xerces.parsers.SAXParser");
//start the server
System.out.println("Starting XML-RPC Server......");
org.apache.xmlrpc.XmlRpc.setEncoding("ISO-8859-1");
WebServer server = new WebServer(8080);
//register our handler class
server.addHandler("hello", new HelloHandler());
server.start();
System.out.println("Now accepting requests......");
}
public static void main(String[] args){
initServer();
}
}
package home.wxk;
public class HelloHandler {
public String sayHello(String name) throws Exception
{
System.out.println("I am come ing..."+name+new String(name.getBytes("UTF-8")+new String(name.getBytes("ISO-8859-1")+new String(name.getBytes()))));
String echo="Hello 你好";
//String returnstr=new String(name.getBytes(),"ISO-8859-1");
return new String(name.getBytes(),"iso-8859-1");
}
}

服务器端的实现
package home.wxk;
import org.apache.xmlrpc.*;
public class RpcServer {
public static void initServer() {
// XmlRpc.setDriver("org.apache.xerces.parsers.SAXParser");
//start the server
System.out.println("Starting XML-RPC Server......");
org.apache.xmlrpc.XmlRpc.setEncoding("ISO-8859-1");
WebServer server = new WebServer(8080);
//register our handler class
server.addHandler("hello", new HelloHandler());
server.start();
System.out.println("Now accepting requests......");
}
public static void main(String[] args){
initServer();
}
}
Handler的实现
package home.wxk;
public class HelloHandler {
public String sayHello(String name) throws Exception
{
System.out.println("I am come ing..."+name+new String(name.getBytes("UTF-8")+new String(name.getBytes("ISO-8859-1")+new String(name.getBytes()))));
String echo="Hello 你好";
//String returnstr=new String(name.getBytes(),"ISO-8859-1");
return new String(name.getBytes(),"iso-8859-1");
}
}
Groovy Beta 8 的一个bug
Beta 8修改了GroovyClassLoader在反复运行大量小脚本的情况下会泄露内存的问题.但是又把GroovyShell.execute的默认行为给修改了.
execute在beta 7中,会首先判定才cache中是否有同名的scriptText,如果有,则运行Cached的脚本.但Beta 8却扔出了一个:duplicate class definition:

回复到:
"Hello William,
In CVS Head, there should be a fix that solved your problem.
When beta-9 is released, could you please check if this issue is still
present? Thanks in advance."
当然,我在Beta 9 released的时候,会检查这个问题是否纠正了.
我的Payroll系统Groovy这可是核心的技术了.
