GWT + Spring hosted mode not working

I have a following problem, probably somebody can help me?

I had an Spring MVC application, quite basic one, with a few simple jsp pages.

Also I had an Spring Security integrated with it.

Now I need to add some GWT widget to one page. No problem so far, I've added <div> to the page, added GWT module, all all needed GWT logic.

When I compile GWT and then deploy application to tomcat - everything works perfectly, I open app, login into it, open my page and see GWT UI components.

Now I want to open my application in hosted mode. There problems begin.

When I start hosted mode, Jetty starts, Spring framework initialize, and then my jsp (translated as .htm) open without hosted mode param ?gwt.codesvr=127.0.0.1:9997. After opening my page I see nothing if I delete compiled gwt code.

When I manually add "?gwt.codesvr=127.0.0.1:9997" hosted mode start and GWT module begin to load. This is when I get an error:

Do you use eclipse ?. If so you need rearrange your exported modules as JDT classes causes problems with the GWT compiler. See comment #7 in this GWT issue about pushing GWT dependencies above others, so that they are picked up first by the compiler.
