apache Digester: Unexspected NoSuchMethodException on addSetNestedProperties

Question

Hi, I have a problem using Digester and I hope you can help me. I have the following Bean:

public class MyEntry {
   private String entityID;

   public String getEntityID() { return this.entityID; }
   public void setEntityID(final String entityID) { this.entityID = entityID; }
}

And the following XML structure:

<entries>
  <entry>
     <MyID>
        24309LAGH1
     </MyID>
  </entry>
</entries>

I use the addSetNestedProperties(…) method of the digester API:

digester.addSetNestedProperties("entries/entry", "MyID", "entryID");

The following exception occurs:

java.lang.NoSuchMethodException: Bean has no property named MyID

Why is digester searching for a property named “MyID”? I specified “entryID” as bean property accorsing to the digester API

Thanks :)

Best regards QStorm

You do not use the correct rule to perform your task.

Try using this instead:

digester.addBeanPropertySetter("entries/entry/MyID", "entityID");

Tips: activate the log4j in your main by using for instance BasicConfigurator.configure();. The output can be very useful.

[edit]

If you want to use addSetNestedProperties:

public class MyEntry {
   private String entityID;

   public String getEntityID() { return this.entityID; }
   public void setEntityID(final String entityID) { this.entityID = entityID; }
}

and for new Digester().parse(myFile);

digester.addObjectCreate("entries/entry", MyEntry.class);
digester.addSetNestedProperties("entries/entry", "MyID", "entityID");
//your propertyName was not the same as in your Bean Class Fields.

and I presume that your Exception was:

java.lang.NoSuchMethodException: Bean has no property named entryID
