Calling repricing from a global component

Question

Hi ,
I want to invoke repricing from my global component,how should i do it.whatever way i found , it required some or other parameters which are not available globally.
Scenario :
In my requirement i need to remove some items from order using global components like Droplets,Processors etc.
I have extended CommerceItemManager's removeItemFromOrder method to suit my needs , the issue is that after remove item from order , i need to invoke repricing (which is automatically invoked when we use form handlers, but here this is not the case ).
i was thinking of calling :
getPurchaseProcessHelper().runProcessRepriceOrder(pPricingOperation, pOrder, pPricingModels, pLocale, pProfile, pExtraParameters, pErrorHandler)
how should i get pPricingModels, pLocale, pProfile, pExtraParameters, pErrorHandler params in my global components.
Note - I dont want to use RepriceOrderDroplet, i want to do it programatically.
Please suggest.
Thanks

This may help you.
================================================================
DynamoHttpServletRequest dynReq = ServletUtil.getCurrentRequest();
OrderHolder shoppingCart = (OrderHolder) dynReq.resolveName(getShoppingCartCompPath());
Profile profile = (Profile)dynReq.resolveName(getProfilePath());
OrderManager orderManager = (OrderManager)dynReq.resolveName(COMPPATH_ORDERMANAGER);
Locale localeVal = getLocale2reprice(shoppingCart.getCurrent(), dynReq);
PricingModelHolder userPricingModels = (PricingModelHolder) dynReq.resolveName(COMPPATH_PRICING_MODELS);
Map<String, Object> parameterMap = new HashMap<String, Object>();
parameterMap.put(PRICING_OP, ORDER_TOTAL);
parameterMap.put(PRICING_MODELS, userPricingModels);
parameterMap.put(LOCALE, locale);
parameterMap.put(PROFILE, profile);
parameterMap.put(ORDER, shoppingCart.getCurrent());
parameterMap.put(COMPNAME_ORDERMANAGER, orderManager);
PipelineResult result = getPurchaseProcessHelper().getPipelineManager().runProcess(repriceChainIdName, parameterMap);
if(pipelineResult != null && pipelineResult.hasErrors()){
Object[] errors = pipelineResult.getErrors();
for (Object currError : errors){
     //you would collect errors here; which can be passed to the invoker
private Locale getLocale2reprice(Order orderVal, DynamoHttpServletRequest dynReq){
Locale locale2reprice = null;
String localeVal = orderVal.getLocale();
if (localeVal == null){
RequestLocale reqLocaleVal = dynReq.getRequestLocale();
if (reqLocaleVal != null && reqLocaleVal.getLocaleString() != null){
localeVal = reqLocaleVal.getLocaleString();
if (localeVal != null){
locale2reprice = new Locale(localeVal);
return locale2reprice;
================================================================
NOTE: The respective profile & order components will be loaded for the logged-in customer.
So, dynReq.resolveName(profile/shoppingCart) will get the right values in the global scoped component.
