Java Beans Connectivity > Java Beans Classes Drop Down Menu is BLANK!

[Former Member]

I'm trying to add data elements to my report based on my java objects (POJO). I cannot seem to get the Java Beans Classes drop down menu to populate despite following the CRConfig.XML tutorial I found on the SAP site.

http://www.sdn.sap.com/irj/boc/go/portal/prtroot/docs/library/uuid/90f892e8-931e-2b10-81a8-9154b9ee7...

1. I pointed my <JavaDir64> to my sdk/bin
   <JavaDir64>C:\Program Files\Java\jdk1.8.0_31\bin</JavaDir64>
2. <JavaDir32></JavaDir32>
3. Added my <JavaBeansClassPath>
   <JavaBeansClassPath>C:\Users\<username>\git\<app>\target\classes\com\company\project\domain</JavaBeansClassPath>
   
   This folder contains my compiled java classes ie. person.java > person.class
4. Opened CR 2013 (trial version) expecting to see the java beans classes populated but it's still blank.

Has anyone ran into this issue?

Resolved...

I should have read the Java Beans Connectivity pdf more carefully. Crystal Reports Designer expects to see a method return a ResultSet.

It does not work like CR4E where you can simply right click the class and add a POJO to a new report.

Using the com.businessobjects.samples.pojo.* pojo api provided by SAP this worked..

public class MonsterService {

  public ResultSet getAllMonsters() {

  List<Monster> monsters = new ArrayList<Monster>();

  monsters.add(new Monster("Bill", 3l, true));

  monsters.add(new Monster("Ralph", 5l, false));

  monsters.add(new Monster("Cory", null, true));

  monsters.add(new Monster("Stan", 3l, false));

  monsters.add(new Monster("Steve", 5l, false));

  POJOResultSet resultSet = getResultSet(monsters);

  return resultSet;

  }

  private POJOResultSet getResultSet(List<Monster> monsters)

  throws POJOException {

  POJOResultSetFactory factory = new POJOResultSetFactory(

  Monster.class);

  POJOResultSet resultSet = factory.createResultSet(monsters);

  return resultSet;

  }

}

To add.. I've also exported my class into a JAR file and added the absolute path directly to this .jar... As the documentation describes.. It does not work for me. The drop down remains blank.
