本文介绍了Eclipse插件开发及调用Web Service的方法。先建立Eclipse插件，在plugin.xml里添加运行调用Web Service所需jar包；接着建立调用Web Service类；然后修改Action类的run方法；最后进行调试，启动Axis服务器和运行时工作台，点击新增按钮调用Webservice并返回结果。

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">

</plugin>
2 建立调用Web Service类，该类实现调用Axis的WebService。

*/
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。
