java - How do JTA Transaction Managers deploy at runtime? -

-

trying wrap head around jta , have arbitrarily chosen bitronix impl because documentation easier (as opposed atmikos makes sign-up , register in order @ src/docs/jars/etc.).

if want use bitronix jta implementation (using tomcat & glassfish), basic architecture (which may basic architecture of jta itself)? is transaction manager actual server/runtime connect (like jms broker)? or api can configure , hit whenever need transaction?

my understanding of jta there is:

  • your code
  • a resource manager - adaptor acid-compliant persistence (like datastore or message broker)
  • a transaction manager - manages transaction api calls between code , resource manager

is bitronix transaction manager , if separate application, separate jar/war has deployed alongside yours, or run "embedded" inside app? in advance!

it runs embedded inside tomcat, , accessible through jndi, other jta transaction managers. whole process of embedding bitronix tomcat described here.

note there no reason use bitronix glassfish, since glassfish full-stack java ee app server , has jta transaction manager.

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...
