生成xorg.conf文件

Posted on 2012/11/04 by neohope — No Comments ↓

1、生成xorg.conf文件

#如果有必要，停止gdm3
service gdm3 stop
#生成空白文件
Xorg -configure
#移动文件
mv ~/xorg.conf.new /etc/X11/xorg.conf
#修改文件，增加需要的分辨率
#如果有必要，开启gdm3
service gdm3 start

2、xorg.conf.new文件

Debian6 Squeeze修改Terminal分辨率

Posted on 2012/11/03 by neohope — No Comments ↓

试了不少方法，要么参数不支持，要不设置了没有用。

好吧，简单暴力一些。

编辑/boot/grub/grub.cfg，在启动参数前，增加两行：

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os {
	#第一行>>>>>>set gfxpayload=1024x768x24
	#第二行>>>>>>load_video
	insmod part_msdos
	insmod ext2
	set root='(hd0,msdos1)'
	search --no-floppy --fs-uuid --set a600ccdc-3768-464b-9b19-29ec051f93e5
	echo	'Loading Linux 2.6.32-5-amd64 ...'
	linux	/boot/vmlinuz-2.6.32-5-amd64 root=UUID=a600ccdc-3768-464b-9b19-29ec051f93e5 ro  quiet text
	echo	'Loading initial ramdisk ...'
	initrd	/boot/initrd.img-2.6.32-5-amd64
}
menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64 (recovery mode)' --class debian --class gnu-linux --class gnu --class os {
	set gfxpayload=1024x768
	insmod part_msdos
	insmod ext2
	set root='(hd0,msdos1)'
	search --no-floppy --fs-uuid --set a600ccdc-3768-464b-9b19-29ec051f93e5
	echo	'Loading Linux 2.6.32-5-amd64 ...'
	linux	/boot/vmlinuz-2.6.32-5-amd64 root=UUID=a600ccdc-3768-464b-9b19-29ec051f93e5 ro single 
	echo	'Loading initial ramdisk ...'
	initrd	/boot/initrd.img-2.6.32-5-amd64
}
### END /etc/grub.d/10_linux ###

修改后为：

### BEGIN /etc/grub.d/10_linux ###
menuentry 'Debian GNU/Linux, with Linux 2.6.32-5-amd64' --class debian --class gnu-linux --class gnu --class os {
	set gfxpayload=1024x768x24

Debian6报错mptctl模块丢失

Posted on 2012/11/03 by neohope — No Comments ↓

1、查看设备是否存在

#执行发现设备不存在
ls /dev | grep mpt
mpt-status
#新建设备
mknod /dev/mptctl c 10 220

2、手动加载模块

modeprobe mptctl
lsmod | grep mpt

3、自动加载模块
编辑/etc/moduels，增加一行

mptctl

4、重启搞定

MyEclipse Access restriction

Posted on 2012/10/31 by neohope — No Comments ↓

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

Posted on 2012/10/30 by neohope — No Comments ↓

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

Posted on 2012/10/22 by neohope — No Comments ↓

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

Posted on 2012/10/22 by neohope — No Comments ↓

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>
