Recycle Bin feature:

Recycle Bin is a new application in the CMC. When the user deletes an item from the BOE system, it is moved to the Recycle Bin, where it is temporarily stored until the Recycle Bin is emptied. This gives the user the opportunity to recover accidentally deleted reports/folders and restore them to their original locations.

With the Recycle Bin application, the administrator can:

Initiate restoration of any deleted item (such as reports and folders)
Permanently delete items from the Recycle Bin
Perform auto-cleanup of the Recycle Bin

If Recycle Bin is enabled, you can recycle the following infoobject types:

Personal folder content
Events
Calendars
Public folder content
Universes
Connections
Public categories
Personal categories
Inboxes
Profiles
Custom roles

In CMC novigate to CMC -> Recycle Bin (listed in Manage column in Home page of CMC).

Enable Recycle Bin using JAVA SDK:

Code to check Recycle Bin enabled or disabled.

Recycle Bin management using JAVA SDK:

Create Enterprise Session using Java SDK:

import com.crystaldecisions.sdk.framework.CrystalEnterprise;
import com.crystaldecisions.sdk.exception.SDKException;
import com.crystaldecisions.sdk.framework.IEnterpriseSession;
...

IEnterpriseSession basicLogon() throws SDKException
{
  ISessionMgr sessionManager = CrystalEnterprise.getSessionMgr();
  IEnterpriseSession enterpriseSession = sessionManager.logon("username", "password", "<cms>:<port>", "secEnterprise");
  return enterpriseSession;
}

List all objects in Recycle Bin:

import com.crystaldecisions.sdk.framework.IEnterpriseSession;
import com.crystaldecisions.sdk.exception.SDKException;

	 String queryString = "SELECT * FROM CI_INFOOBJECTS WHERE SI_KIND = '" +IRecycleBinObject.KIND+"'";

	 IInfoObjects infoObjects = infoStore.query(queryString);

	 Iterator infoObjectsIter = infoObjects.iterator();
	 while(infoObjectsIter.hasNext()) {
		 IRecycleBinObject rbObject = (IRecycleBinObject) infoObjectsIter.next();
	     System.out.println(rbObject.getTitle());
	 }
	 return infoObjects;
 }

	 System.out.println(rbObject.getTitle());
	 System.out.println(rbObject.getMainRecycledObjectType());
	 System.out.println(rbObject.getOwner());
	 System.out.println(rbObject.getKind());
	 //........
 }

Permanently delete objects from recycle bin:

...

void deleteRecycleBinObject(IEnterpriseSession enterpriseSession) throws SDKException
 {
	 IInfoStore infoStore = (IInfoStore) enterpriseSession.getService("InfoStore");
	 String queryString = "SELECT * FROM CI_INFOOBJECTS WHERE SI_KIND = '" +IRecycleBinObject.KIND+"'";

	 IInfoObjects infoObjects = infoStore.query(queryString);
	 IRecycleBinObject rbObject = (IRecycleBinObject) infoObjects.get(0);
	 System.out.println(rbObject.getTitle());
	 rbObject.deleteNow();
