Walker, who was in Milwaukee over the weekend for his first annual charity softball game, told reporters that no progress has been made between Rosenhaus and the Packers.
"There's been nothing in response," Walker said. "Their attitude is they're going to do something when they're ready."
Walker has two years remaining on the $7.485 million rookie contract he signed in 2002, which paid him $4.3 million in guaranteed money and calls for him to receive base salaries of $515,000 this year and $650,000 next year.
The wide receiver said Saturday he was unsure whether he would be at the Packers' next mini-camp, which begins June 1, but he is hopeful a deal will be reached before training camp begins in late July.
He skipped a mandatory minicamp last month due to the salary dispute.
"Like I said, I want to be here. I don't want to go nowhere," Walker said at his Celebrity Softball Slam at Miller Park Saturday, which drew 13,447 fans.
Walker went to his first Pro Bowl last season after catching 89 passes for for 1,382 yards and 12 touchdowns during the 2004 regular season.
He received a mix of boos and cheers from the fans at the softball game Saturday.
Walker spoke to the fans during the softball game. His All Stars lost to the Hitters, captained by Packers linebacker Nick Barnett, 9-8. He pleaded with Packers fans to understand that the contract situation was just the business side of the NFL.
"It's not about the person," Walker said.
"I'm here for the charity. The people are why I am here today. If it wasn't for them, no one would know who Javon is. I'm not a guy who is going to hide. The fans are the ones who are buying the tickets," he said.
Walker continues to say that he doesn't want to be traded and wants to finish his career in Green Bay. He is hoping to get the contract dispute resolved by the start of training camp.
"I don't think it will get that ugly. I want to be here, I don't want to go nowhere," Walker said. "My situation is different than a lot of guys out there. I don't think it will ever get that ugly. I don't want it to get that ugly just for the simple fact that I love the state of Wisconsin.
"I'm looking at the turnout of this game and I'm telling myself, people are showing up at this event for me. I consider myself not going anywhere, continuing to do this event every year. Hopefully it will get bigger."
Rosenhaus declined to speak of Walker's contract situation, but he did play in the softball game and was booed loudly by the fans. When he grounded out in his only at bat, Miller Park erupted with cheers.
