问题：
Access restriction: The type Handler is not accessible due to restriction on required library xxxx.jar
原因：
MyEclipse运行使用的JDK/JRE，与工程的JDK/JRE不同所致
解决方法：
在项目属性中，JDK/JRE设成默认就好啦
VMWare扩展及压缩虚拟磁盘
1、扩展虚拟磁盘
1.1A我的xp虚拟机一共只有10G，我需要扩展到20G（要关虚拟机）
"D:\Program files\VMware\VMware Workstation\vmware-vdiskmanager.exe" -x 20GB "D:\VirtualMashines\VMware\WinXP\WinXP.vmdk"
1.1BVMWare10以后，可以直接在管理工具中
虚拟机-》设置-》硬盘-》实用工具-》扩展
1.2扩展后，开启虚拟机，自己到磁盘管理器中分配空间即可。
2、压缩WinXP虚拟磁盘（vmware-tools）
2.1管理工具（关闭虚拟机）
虚拟机-》设置-》硬盘-》实用工具-》碎片整理
2.2开启虚拟机
系统托盘图标-》vmware-tools-》压缩
3、压缩WinXP虚拟磁盘（vmware-vdiskmanager）
3.1需要到微软官网下载sdelete工具，然后在虚拟机中运行：
sdelete -z
3.2关闭虚拟机，运行：
"D:\Program files\VMware\VMware Workstation\vmware-vdiskmanager.exe" -k "D:\VirtualMashines\VMware\WinXP\WinXP.vmdk"
4、压缩Debian虚拟磁盘：
4.1A在虚拟机中运行zerofree命令，需要将分区挂载为只读模式
apt-get install zerofree umount /etc/home zerofree /dev/sda6
4.1B在虚拟机中运行dd命令，需要将分区挂载为读写模式
dd if=/dev/zero of=/bigemptyfile rm bigemptyfile
4.2关闭虚拟机，运行：
"D:\Program files\VMware\VMware Workstation\vmware-vdiskmanager.exe" -k "D:\VirtualMashines\VMware\Debian8\Debian8.vmdk"
5、压缩FreeBSD虚拟磁盘：
5.1A在虚拟机中运行dd命令，需要将分区挂载为读写模式
dd if=/dev/zero of=bigemptyfile bs=1m rm bigemptyfile
5.1B在虚拟机中运行dd命令，需要将分区挂载为读写模式（适用于影片空闲空间较小）
cat /dev/zero > bigemptyfile;sync;sleep 1;sync; rm -f bigemptyfile
5.2关闭虚拟机，运行：
"D:\Program files\VMware\VMware Workstation\vmware-vdiskmanager.exe" -k "D:\VirtualMashines\VMware\FreeBSD10\Debian8.vmdk"
Axis2 WebService Client
1、Axis2调用WebService一般有两种方法：
a、使用org.apache.axis2.rpc.client.RPCServiceClient自动生成PayLoad
b、使用org.apache.axis2.client.ServiceClient手动生成PayLoad
package com.ats.ws.client;
import javax.xml.namespace.QName;
import org.apache.axiom.om.OMAbstractFactory;
import org.apache.axiom.om.OMElement;
import org.apache.axiom.om.OMFactory;
import org.apache.axiom.om.OMNamespace;
import org.apache.axis2.AxisFault;
import org.apache.axis2.addressing.EndpointReference;
import org.apache.axis2.client.Options;
import org.apache.axis2.client.ServiceClient;
import org.apache.axis2.rpc.client.RPCServiceClient;
import org.apache.log4j.Logger;
import com.ats.db.Person;
import com.ats.db.PersonAddResponse;
public class WSInvoker
{
private static Logger logger = Logger.getLogger(WSInvoker.class);
private static void invokeWebServiceRPC()
{
try
{
RPCServiceClient serviceClient = new RPCServiceClient();
Options options = serviceClient.getOptions();
options.setTo(new EndpointReference("http://localhost:8080/WebService1/services/PersonManager"));
// 调用Action
QName operation = new QName("http://ws.ats.com", "PersonAdd");
// 调用参数类型和参数值
Person p = new Person();
Object req[] = new Object[] { p };
p.setName("HI");
Class[] reqClasses = new Class[] { PersonAddResponse.class };
// 返回结果
Object[] rsp = serviceClient.invokeBlocking(operation, req, reqClasses);
PersonAddResponse r = (PersonAddResponse) rsp[0];
logger.debug(r.getOperationReult());
} catch (AxisFault e)
{
e.printStackTrace();
}
}
public static void invokeWebServiceDocument()
{
try
{
ServiceClient serviceClient = new ServiceClient();
Options opts = new Options();
opts.setTo(new EndpointReference("http://localhost:8080/WebService1/services/PersonManager"));
opts.setAction("urn:PersonAdd");
serviceClient.setOptions(opts);
// 发送请求并并得到返回结果
OMElement res = serviceClient.sendReceive(createPayLoad());
logger.debug(res.getFirstElement().getText());
} catch (AxisFault e)
{
e.printStackTrace();
}
}
public static OMElement createPayLoad()
{
OMFactory fac = OMAbstractFactory.getOMFactory();
// 命名空间
OMNamespace omNsXSD = fac.createOMNamespace("http://ws.ats.com", "xsd");
OMNamespace omNsXS = fac.createOMNamespace("http://www.w3.org/2001/XMLSchema", "xs");
// 指定方法
OMElement method = fac.createOMElement("PersonAdd", omNsXSD);
// 指定方法的参数
OMElement p1 = fac.createOMElement("person", omNsXS);
OMElement personName = fac.createOMElement("personName", omNsXS);
personName.setText("personName");
p1.addChild(personName);
OMElement personid=fac.createOMElement("personid", omNsXS);
personid.setText("");
p1.addChild(personid);
method.addChild(p1);
return method;
}
public static void main(String[] args)
{
WSInvoker.invokeWebServiceRPC();
WSInvoker.invokeWebServiceDocument();
}
}
2、要想看到网络通讯的话，在log4j的配置文件中增加：
<category name="org.apache.commons.httpclient"> <priority value="WARN" /> </category> <category name="httpclient.wire"> <priority value="DEBUG" /> </category>
Axis2 WebService Server
1、发布的几种方式
POJO+axis2-war：
这种方式比较适合简单功能，直接写一个POJO，放到axis2-war下的pojo目录即可
AAR+axis2-war:
这种方式比较适合发布，将服务打成aar包，放到axis2-war下的service目录即可
web+axis2:
这种方式比较适合调试，将axis2集成到web工程，个人比较喜欢这个方式
2、Service组成
a、服务类
PersonManager.java
package com.ats.ws;
import com.ats.db.Person;
import com.ats.db.PersonAddResponse;
import com.ats.db.PersonDAO;
public class PersonManager {
public PersonAddResponse PersonAdd(Person person)
{
PersonAddResponse rsp = new PersonAddResponse();
//PersonDAO dao = new PersonDAO();
//rsp.setOperationReult(dao.InsertPerson(person));
return rsp;
}
}
b、服务描述文件
services/Person/META-INF/services.xml
<?xml version="1.0" encoding="UTF-8"?> <service name="PersonManager"> <description>PersonManagere</description> <parameter name="ServiceClass">com.ats.ws.PersonManager</parameter> <operation name="PersonAdd"> <messageReceiver class="org.apache.axis2.rpc.receivers.RPCMessageReceiver" /> </operation> </service>
c、wsdl
可以自动生成，一般不需要指定
3、Axis2集成到WebApp的方式
a、axis2-web拷贝到project/WebContent下
b、conf、modules、services拷贝到project/WebContent/WEB-INF下
c、所需lib，拷贝到project/WebContent/WEB-INF/lib下
c、web.xml增加下面内容：
<servlet> <servlet-name>AxisServlet</servlet-name> <servlet-class>org.apache.axis2.transport.http.AxisServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet> <servlet-name>AxisAdminServlet</servlet-name> <servlet-class>org.apache.axis2.webapp.AxisAdminServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/servlet/AxisServlet</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>*.jws</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping> <servlet-mapping> <servlet-name>AxisAdminServlet</servlet-name> <url-pattern>/axis2-admin/*</url-pattern> </servlet-mapping>
