The type com.sun.java.util.jar.pack.Package is not visible产生的原因？

源程序：
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.File;

import org.apache.struts2.ServletActionContext;

import com.opensymphony.xwork2.ActionSupport;
import com.sun.java.util.jar.pack.Package.File;

public class MyUpAction extends ActionSupport {

public File getUpload() {
return upload;
}

public void setUpload(File upload) {
this.upload = upload;
}

public String getUploadContentType() {
return uploadContentType;
}

public void setUploadContentType(String uploadContentType) {
this.uploadContentType = uploadContentType;
}

public String getUploadFileName() {
return uploadFileName;
}

public void setUploadFileName(String uploadFileName) {
this.uploadFileName = uploadFileName;
}

public String getSavaPath() {
return savaPath;
}

public void setSavaPath(String savaPath) {
this.savaPath = savaPath;
}

private File upload;
private String uploadContentType;
private String uploadFileName;
private String savaPath;
public String getSavePath()throws Exception{

return ServletActionContext.getRequest().getRealPath(savaPath);
}

public String excute()throws Exception{

String fileName=getSavePath()+"\\"+getUploadFileName();

FileOutputStream fos=new FileOutputStream(fileName);
FileInputStream fis=new FileInputStream(getUploadFileName());

byte[] b=new byte[1024];
int len=0;
while((len=fis.read(b))>0){
fos.write(b, 0, len);
}
return SUCCESS;

}
}

出错的地方：
import com.sun.java.util.jar.pack.Package.File;
出错提示内容为：
The type com.sun.java.util.jar.pack.Package is not visible

提问：请问各位高手是什么原因？
拜谢！
