java - How do you redirect to another URI and access an object from the previous modelAndView -

i have next code. want access booleanvalueobj on nextpage.jsp. how done? object not available nextpage() method on every request, requestparam seems it's not appropriate.

@requestmapping(method=requestmethod.post) public modelandview sendemail() { modelandview modelandview = new modelandview(); modelandview.addobject(booleanvalueobj, true); modelandview.setviewname("redirect: /nextpageclass"); homecoming modelandview; } @requestmapping("/nextpageclass") public class nextpagecontroller { @requestmapping(method = requestmethod.get) public modelandview nextpage() { modelandview modelandview = new modelandview("/nextpage"); homecoming modelandview; } }

you can't pass booleanvalueobj redirected page. if booleanvalueobj boolean value, seems appropriate passed /nextpageclass thru request parameters.

@requestmapping(method=requestmethod.post) public modelandview sendemail(httpservletresponse resp) { resp.sendredirect("/nextpageclass?booleanvalueobj=true"); homecoming null; } @requestmapping("/nextpageclass") public class nextpagecontroller { @requestmapping(method = requestmethod.get) public modelandview nextpage(httpservletrequest req) { modelandview modelandview = new modelandview("/nextpage"); boolean booleanvalueobj = null; string booleanvalueparam = req.getparameter("booleanvalueobj"); if (booleanvalueparam != null) booleanvalueobj = boolean.parse(booleanvalueparse); modelandview.addobject("booleanvalueobj", booleanvalueobj); homecoming modelandview; } }

actionscript 3 - Flex: moving a point with rotation doesnt change the point XY? - i have follow issue : i have point setted @ border on component, changed transform point center of component in order match component rotation. the of import part when seek point xy after rotation - remains same before rotation. how xy, after rotation ( changeing point.rotation property specific degrees of rotaion ) if want point after rotation, cos(r) * x, sin(r) * y easiest way. if want point after transformations, should able utilize displayobject.transform.transformpoint(x, y) . there's displayobject.localtoglobal . in case phone call localtoglobal(x, y) , localtoglobal(0, 0) , calculate difference. see transform livedocs , displayobject livedocs flex actionscript-3
