Re: [Simple-support] PersistenceException: constructor not matched for class error when deserializing XML file

You need to annotate the constuctor arguments.

Hi,

I'm using Simple to create an XML file called BackupInfo.xml from this class:

@Root
public class BackupInfo {
    @Attribute
    private String backupName;
    @Element
    private int numberOfFiles;

    @ElementList 
    private ArrayList<FileInfo> files;
    @Element
    private Date date;
}

@Root 
class FileInfo{
    @Attribute
    public String fileName;
    @Element
    private String path;

    @Element
    private long fileSize;
    
    public FileInfo(String name, String aPath, long size) {
        fileName = name;
        path = aPath;
        fileSize = size;
    }
    
    public String getName(){

        return fileName;
    }
    
    public String getPath(){
        return path;
    }
}    

When I serialize it I get a XML file that looks like this:


-    <backupInfo backupName="1">
   <files>
      <fileInfo>
         <fileName>sms.xml</fileName>

         <path>/sdcard/sms.xml</path>
         <fileSize>2807</fileSize>
      </fileInfo>
      <fileInfo>
         <fileName>calllog.xml</fileName>
         <path>/sdcard/calllog.xml</path>

         <fileSize>1611</fileSize>
      </fileInfo>
      <fileInfo>
         <fileName>contacts.xml</fileName>
         <path>/sdcard/contacts.xml</path>
         <fileSize>1679</fileSize>

      </fileInfo>
   </files>
   <date>2011-01-21 16:55:15.63 GMT+00:00</date>
   <numberOfFiles>3</numberOfFiles>
</backupInfo>

Then I try to deserialize using:
     serializer = new Persister();
     File info = new File ("/sdcard/BackupInfo.xml");
     BackupInfo bi = serializer.read(BackupInfo.class, info);

At this point, I get the PersistenceException: Constructor not matched for class com.data.FileInfo


How do I solve this error? I searched everywhere (tutorial, google, this mail list) but couldn't find an answer.

Thx,
Thalisson
