England, who have a final warm-up game against France at Henley on Saturday, have named a 26-man squad coached by Nigel Redman and Mark Mapletoft.
The squad includes six of the players who helped England to a best-ever third place at last year's tournament in Dubai - captain Hugo Ellis (London Wasps), Ben Thomas (Saracens), Andy Saull (Saracens), Richard Bolt (Exeter Chiefs), Joe Simpson (London Wasps) and Adam Greendale (Leeds Tykes).
Former Bath, England and Lions lock Redman is looking forward to seeing his players rise to the challenge of improving on last year's performance.
England face group games against Samoa, Argentina and New Zealand before the knock-out stages that climax in the finals day on April 21.
"Going to a World Championship is a big step up from club level as we face five games in three-and-a-half weeks and it'll be fascinating to see how they cope in that situation," Redman said.
England open their campaign against Samoa at Shaw's Bridge on April 5 (7.30pm), then face Argentina at Belfast Harlequins on April 9 (7.30pm) and last year's runners-up New Zealand at Ravenhill on April 13 (5.30pm).
