1 建立Eclipse插件

File->New->PRoject->Plug-in development的Plug-in project->Next,填写Project名,Next, 填写内容,Next,选择Create plug-in using one of the templates,选择Hello,World,Finish。

在视图可看到plugin.xml,在<Runtime>里加上运行调用Web Service所需jar包。内容如下:

<?xml version="1.0" encoding="UTF-8"?>
<?eclipse version="3.0"?>
<plugin
  id="colimas_plugin"
  name="Colimas_plugin Plug-in"
  version="1.0.0"
  provider-name="nova"
  class="colimas_plugin.Colimas_pluginPlugin">

  <runtime>
   <library name="colimas_plugin.jar">
     <eXPort name="*"/>
   </library>
   <library name="lib/activation.jar">
     <export name="*"/>
   </library>
   <library name="lib/axis.jar">
     <export name="*"/>
   </library>
   <library name="lib/commons-beanutils.jar">
     <export name="*"/>
   </library>
   <library name="lib/commons-discovery-0.2.jar">
     <export name="*"/>
   </library>
   <library name="lib/commons-logging-1.0.4.jar">
     <export name="*"/>
   </library>
   <library name="lib/jaxrpc.jar">
     <export name="*"/>
   </library>
   <library name="lib/xalan.jar">
     <export name="*"/>
   </library>
   <library name="lib/xerces.jar">
     <export name="*"/>
   </library>
   <library name="lib/saaj.jar">
     <export name="*"/>
   </library>
   <library name="lib/mail.jar">
     <export name="*"/>
   </library>
  </runtime>

  <requires>
   <import plugin="org.eclipse.ui"/>
   <import plugin="org.eclipse.core.runtime"/>
  </requires>

  <extension
     point="org.eclipse.ui.actionSets">
   <actionSet
      label="Sample Action Set"
      visible="true"
      id="colimas_plugin.actionSet">
     <menu
        label="Sample &Menu"
        id="sampleMenu">
      <separator
         name="sampleGroup">
      </separator>
     </menu>
     <action
        label="&Sample Action"
        icon="icons/sample.gif"
        class="colimas_plugin.actions.SampleAction"
        tooltip="Hello, Eclipse world"
        menubarPath="sampleMenu/sampleGroup"
        toolbarPath="sampleGroup"
        id="colimas_plugin.actions.SampleAction">
     </action>
   </actionSet>
  </extension>

</plugin>


2 建立调用Web Service类,该类实现调用Axis的WebService

/*

*
* TODO To change the template for this generated file go to
* Window - Preferences - java - Code Style - Code Templates
*/
package com.nova.colimas.plugin.eclipse;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import javax.xml.namespace.QName;
import java.io.*;
/**
* @author tyrone
*
* TODO To change the template for this generated type comment go to
* Window - Preferences - Java - Code Style - Code Templates
*/
public class SendFileClient {

private Call call;
/**
 * The constrUCtor.
 */
public SendFileClient() {
 try{
  Service service= new Service();
  call  = (Call) service.createCall();
 }catch(Exception ex){
  System.out.println(ex.getMessage());
 }
}

public void saveFile(){
 try {
  String endpoint =
  "http://localhost:8080/axis/services/DocumentFileManagement";
  System.out.println("start web service");
  call.setTargetEndpointAddress( new java.net.URL(endpoint) );
  call.setOperationName(new QName("http://soapinterop.org/", "saveFile"));
  File fp=new File("D:\\MyProject\\colimas\\colimas_plugin\\lib\\mail.jar");
  BufferedInputStream in=new BufferedInputStream(new FileInputStream(fp));
  int len=in.available();
  byte[] contents=new byte[len];
  in.read(contents,0,len);
  System.out.println("begin run");

//开始调用Web Service:DocumentFileManagement的saveFile方法

  String ret = (String) call.invoke( new Object[] {fp.getName(),contents} );
  in.close();
 } catch (Exception e) {
  System.err.println("error"+e.toString());
 }
}

}


3 修改Action类的run方法

Action类的run方法里的内容是Eclipse插件真正要做到事

package colimas_plugin.actions;

import org.eclipse.jface.action.IAction;
import org.eclipse.jface.viewers.ISelection;
import org.eclipse.ui.IWorkbenchWindow;
import org.eclipse.ui.IWorkbenchWindowActionDelegate;
import org.eclipse.jface.dialogs.MessageDialog;

import com.nova.colimas.plugin.eclipse.*;
/**
* Our sample action implements workbench action delegate.
* The action proxy will be created by the workbench and
* shown in the UI. When the user tries to use the action,
* this delegate will be created and execution will be
* delegated to it.
* @see IWorkbenchWindowActionDelegate
*/
public class SampleAction implements IWorkbenchWindowActionDelegate {
private IWorkbenchWindow window;
/**
 * The constructor.
 */
public SampleAction() {
}

/**
 * The action has been activated. The argument of the
 * method represents the 'real' action sitting
 * in the workbench UI.
 * @see IWorkbenchWindowActionDelegate#run
 */
public void run(IAction action) {
 SendFileClient client=new SendFileClient();
 client.saveFile();
 MessageDialog.openInformation(
  window.getShell(),
  "Colimas_plugin Plug-in",
  "Colimas Connected");
}

/**
 * Selection in the workbench has been changed. We
 * can change the state of the 'real' action here
 * if we want, but this can only happen after
 * the delegate has been created.
 * @see IWorkbenchWindowActionDelegate#selectionChanged
 */
public void selectionChanged(IAction action, ISelection selection) {
}

/**
 * We can use this method to dispose of any system
 * resources we previously allocated.
 * @see IWorkbenchWindowActionDelegate#dispose
 */
public void dispose() {
}

/**
 * We will cache window object in order to
 * be able to provide parent shell for the message dialog.
 * @see IWorkbenchWindowActionDelegate#init
 */
public void init(IWorkbenchWindow window) {
 this.window = window;
}
}


4 调试

首先启动Axis服务器,然后选择Eclipse的Run菜单的Run As -〉Run time workbench。


这样会启动另一个Eclipse workbench,在这个workbench里你会看到toolbar里新增了一个按钮,

点击按钮就会调用Webservice并返回控制台结果。
