can call 1 ejb3 session bean (statless/statefull) method other method in same session bean ? state of members save between calls ? yes, can. use @resource sessioncontext inject instance, , use getbusinessobject (or getejbobject or getejblocalobject depending on view want); see javadoc methods. for stateless beans, invocation on new bean instance. depending on you're trying do, can simpler use @ejb yourinterface directly inject proxy rather using sessioncontext. for stateful beans, state of bean "preserved" because you'll invoking same underlying bean instance.

i trying see via reg ex if user gave correct input(user should give complex number), , dependent on input program should give action. so far have 3 reg expressions comparison: @"([-]?[1-9][0-9]*[+|-][1-9][0-9]*i)+" @"([-]?[1-9][0-9]*)+" @"([-]?[1-9][0-9]*[i])+" in case want see if complex number given correctly, use first reg ex. if not given correctly want use other 2 expressions see if user used abbreviations input. the problem if user gives 3i in program real number, because of reg ex. reg ex testing if part of string correct, , want know if entire string correct. for example if type 3i3 , if use third expression, result true, , want true 3i. if want make regex matches entire string, add ^ , $ anchors it: @"^([-]?[1-9][0-9]*[+|-][1-9][0-9]*i)+$" @"^([-]?[1-9][0-9]*)+$" @"^([-]?[1-9][0-9]*[i])+$" ^ @ beginning means match must start @ beginning of input string $ @ end means there must no ch...

how define optional characters in group? i trying match following... kg kilo kilos kilogram kilograms g gram grams i know can put them individually in group, wondering if fancy this... (kg|kilo?g?ram?s?) problem match s? or none of second alternation match 0 length. i start enumerating of possible match conditions , paring down there see if there more efficient solution: kg|kilo|kilos|kilogram|kilograms|g|gram|grams the plural 's' obvious redundancy: kg|kilos?|kilograms?|g|grams? g , kg can collapsed: k?g|kilos?|kilograms?|grams? we can collapse units kilograms: k?g|kilo(?:s|grams?)?|grams? are ok 6 character duplication of "grams?" :)
