java - Using JAXB with signatures, encryption and encoding -

-

recently we've been tasked coming xml communication specification our products. few of coworkers have high opinions of jaxb marshalling , unmarshalling xml docs. i've spent time playing around , understand coming from. makes life simple simple xml docs.

now take notch. 1 of things see in our communication model "built in" signature validation people use after me. 1 of problems i'm running validate signature need treat corresponding xml bytes. let's take example...

<toplevel>     <sensitivedata encoding="utf8">         <creditcard>             <number>1234-1234-1234-1234</number>             <expdate>oct 2020</expdate>         </creditcard>     </sensitivedata>     <signatureofsensitivedata algorithm="sha1withrsa">vghpc0lzqvnpz25hdhvyzq==</signatureofsensitivedata> </toplevel>

edit: not passing credit card data. example here.

what great if byte[] (determined encoding) representation of inside of "sensitivedata" tag. wouldn't mind having call "unmarshall" again on byte[].

this opens other doors us. introduce "compression" , "encryption" attributes elements. if treat them byte[] inflate , decrypt them , pass them on unmarshalled again.

side note: think works if base64 encode xml , include in element. forces base64 simple documents , introduce unnecessary bloat our messages.

any ideas solutions this? hope i'm missing basic in jaxb , breeze after that.

thanks!

c# - Copy ObservableCollection to another ObservableCollection -

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
