Hey

I wrote a little test programm for different databases. now I want to add cassandra, but I get an Error with one field.

Code:

The Entity with the problematic property:

Code:

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "LogEntry", namespace = "http://www.rohde-schwarz.de/schemas/types/logEntry", propOrder = {
      "id", "log_index", "code", "date", "level", "activity",
      "component", "resource", "parameters", "serverErrorCode", "userName", "objectName", "parametersList"
})
@Entity
// @Table(name = "HISTORY_LOG")
@Indexed
public class LogEntry {



   public enum LEVEL {
      error,
      warning,
      info;
   }
   

   public static final String TYPE_NAME = "LogEntry";
   public static final String DEFAULT_USERNAME = "SYSTEM";
   public static final String AVHE_CONTROL_USERNAME = "AVHE_CONTROL";
   

   @XmlElement(required = true)
   @Id
   private String id = "GUID_FOR_EMPTY";

   @XmlElement(required = true, name = "index")
   @Field(analyze = Analyze.NO)
   private long log_index = 0;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String code;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private long date;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   @Enumerated(EnumType.STRING)
   private LEVEL level;


   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String activity;
   
   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String resource;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String component;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String serverErrorCode;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String objectName;

   @XmlElement(required = true)
   @Field(analyze = Analyze.NO)
   private String userName = DEFAULT_USERNAME;

   @XmlElement(required = true)
   @Transient
   private Map<String, String> parameters = new HashMap<>();

   @OneToMany(cascade = CascadeType.ALL)
   @IndexedEmbedded
   private Set<Parameter> parametersList;

   
   public LogEntry() {
      for (Entry<String, String> entry : parameters.entrySet()) {
         parametersList.add(new Parameter(log_index, entry.getKey(), entry.getValue()));
      }
   }


//Getters and Setters,hashcode, toString and so on

   

}

I use a maven project, mongoDB, mySQL and PostgreSQL work fine...
does anybody know what I did wrong?

edit: i started my trial and it seems that the problem is the newer core I use. because since I use 4.2.0 the problem appears for mongoDB, too.
But for using the cassandra driver I need core 4.2.0 any hints?

Hi,

I tried to reproduce the issue using your LogEntry entity but it works as expected for me. It's really odd, of course there is support for String. Just to be sure, maybe you accidentally import another "String" type rather than java.lang.String? It's unlikely, but the only explanation coming to my mind. If you can provide a minimal example project (small Maven project, just the concerned entity and code using it) and attach it to an issue in our tracker (https://hibernate.atlassian.net/browse/OGM) I can try and take a closer look.

Cheers,

--Gunnar

Thank you for your answer Gunnar,

I am back in office on thursday. I will try to reproduce the error in a smaller project and attach it.

cheers
Ruth
