The 19-year-old Neeraj, the current world junior record holder, had carried the hopes of the entire country but failed to make it to the final round.
He could not cleared the automatic qualification mark of 83m. It was compatriot Davinder Singh Kang, who managed to make the cut, becoming the first Indian to qualify for the javelin throw final round in a World Championships.
"I need some time to do that, to improve my technique. I have been taking part in competitions continuously for the last four-five months. Now I want some time for training to prepare myself for future events. I am waiting for the new coach to come," he added.
In the qualification round on Thursday, Neeraj cleared 82.26m in his opening throw, 74 centimeters short of the automatic qualification mark.

"I was confident that I would be able to touch 83m and get the automatic qualification. I made a big effort in the first throw but it was short of 83m mark by a few centimeters. Then in the second throw, I was going for the attack but I was off-balance in the run up and fouled it. The third and final throw also came short," said a dejected Neeraj.
Neeraj came without a coach as former javelin throw world record holder Uwe Hohn of Germany is yet to join the national team. Hohn is still with the Australian team and he is expected to join as India javelin coach later this year.
"After (former coach) Gary Calvert left, I have been mostly doing training all alone. I am waiting for the new coach to come. A person who knows the techniques lets you do a lot of work. So I am waiting (for the new coach).
Athletes are allowed to bring their javelin in the World Championships, which is checked by the IAAF, but Neeraj did not have one as he came straight to London after competing in the Monaco leg of the Diamond League meetings on July 21.
"I came here straight from Monaco after the Diamond League there, so I could not bring my javelin. It is good if you come with your javelin with which you do practice.
