java - How to write content before and after the output of a JSP -

-

i have jpss represent components. want have these component jsps write html before , after contents of jsp executed.

component.jsp

<@page session="false"> <%= "hello " + "world" %>

when jsp/servlet rendered, want render:

<div class="component"> hello world </div>

i want able create various "wrappers", , depending on jsp, include wrap contents of jsp correct content. if want change/augment wrapper down road, want in 1 place (could 100s of components).

can <@page extends="..."> possibly?

thanks

what want named: tag files. introduced on jsp 2.0

with approach can write jsp tags using jsp, therefore need create folder named web-inf/tags, , create 'normal' jsp within folder.

the tag want create needs have following start instruction: <%@tag description="tag description" %> in order indicate tag.

to use need reference tags want use following instruction: <%@ taglib tagdir="/web-inf/tags" prefix="custom"%>

so, can like: web-inf/tags/mytag.tag

<%@tag description="hello tag" %> <%@attribute name="name" required="false" type="java.lang.string"%> <html><head></head><body> <h1>hello <%=name%></h1> <jsp:dobody /> </body>

index.jsp

<%@ taglib tagdir="/web-inf/tags" prefix="custom"%> <custom:mytag name="my name">this content</custom:mytag>

the result page printing 

<html><head></head><body> <h1>hello name</h1> content </body>

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...
