Hey All:
  Recently,I need to write a program to download file form the alfresco.The following is my code.
  public class download_test {
   //Url(include port)
   protected static final String Url = "http://localhost:8080/alfresco/api";
   //UserName Key
   protected static final String UserName = "admin";
  //PassWord key
   protected static final String PassWord = "admin";
  //Upload SerVice Folder
   protected static final String ServiceFolderName = "GDV/Open";
  /** The store used throughout the samples */
   protected static final Store STORE = new Store(Constants.WORKSPACE_STORE, "SpacesStore");
/**  * @param args */
public static void main(String[] args) throws Exception
{
  // TODO Auto-generated method stub 
  /**Set repository location*/
   WebServiceFactory.setEndpointAddress(Url);
/**Start the session*/
   AuthenticationUtils.startSession(UserName, PassWord);
/** Make sure Service Folder has been created,or download files will be failure */ 
  boolean Success = true;
  String[] ServiceFolderList = ServiceFolderName.split("/");
  String ParentFolder = "/app:company_home";
  String ServiceFolder;
  Reference SAMPLE_FOLDER;
  for(String mServiceFolder :ServiceFolderList) {
     ServiceFolder = ParentFolder+"/cm:"+mServiceFolder;
    SAMPLE_FOLDER = new Reference(STORE, null, ServiceFolder);
   try  {
    WebServiceFactory.getRepositoryService().get(new Predicate(new Reference[]{SAMPLE_FOLDER}, STORE, null));
    } catch (Exception exception) {
    //jmp to /** End the session*/ 
   Success=false;
    break;
    }
    ParentFolder = ServiceFolder; }
   System.out.println(ParentFolder);
    /**Download files,if exception then "Success = False" */ 
   if(Success) {
   // Get the content service 
   ContentServiceSoapBindingStub contentService = WebServiceFactory.getContentService();
  //Search the content int the ServicrFolder
   Content mcontent = SearchContent(contentService,ParentFolder,"1kkk.jpg");  DownLoadFileFromAlfresco(mcontent,"d:/1kkk.jpg"); '
   }
   /** End the session*/ 
   AuthenticationUtils.endSession(); }

    public static void DownLoadFileFromAlfresco(Content content,String destFolder) throws Exception {
       InputStream in=ContentUtils.getContentAsInputStream(content);
      //Output file
     File file=new File(destFolder);
         if(!file.exists()) file.createNewFile();
         FileOutputStream out=new FileOutputStream(file);
         int c;
          byte buffer[]=new byte[1024];
        while((c=in.read(buffer))!=-1)
       {
             for(int i=0;i<c;i++)
           out.write(buffer);
          }
         in.close();
         out.close();
        System.out.println("download ok!");
     }
    public static String modiflyRefenceName(String FileName) {
           if(FileName.charAt(0)>='1'&&FileName.charAt(0)<='9') {
                           String ModifliedName ="_x003"+FileName.substring(0,1)+"_"+FileName.substring(1);
                           System.out.println(ModifliedName); return ModifliedName;
                   }
                           return FileName;
}
public static Content SearchContent(ContentServiceSoapBindingStub contentService, String srcFolder,String FileName) throws Exception {
  String FileRefenceName = modiflyRefenceName(FileName);
  Reference contentReference = new Reference(STORE,null,srcFolder+"/cm:"+FileRefenceName);
  Content[] readResult = contentService.read( new Predicate(new Reference[]{contentReference}, STORE, null), Constants.PROP_CONTENT);
  System.out.println(readResult[0].getUrl());
   for(Content content: readResult) {
       String[] SplitedUrl = content.getUrl().split("/");
        if(SplitedUrl[SplitedUrl.length-1].equals(FileName))
             { return content; }
       }
        return null; }
}
I meet a problem,when the fileName which we will download from alfresco like this "Iberdrola SA (2009-03-24).xls".I got thefollowing exception:
