java - Access image file inside a Jar file dynamically -


i have java project,exported jar file (desktop application) generates html file output. output html file, needs read 1 image file, page's logo. jar application in x folder. target html file placed dynamically anywhere. how make html,residing in someother location, access image, inside jar file.

in short, how determine path below code, above scenario.

java.net.url url = getclass().getresource("image.jpg"); fw.write("<tr><td><b>"+csname+"</b></td><td> <img src = "+url.tostring()+"'>/td></tr>");

works fine, when run in eclipse. not when exported jar resultant html file,in other folder has code

<img src="rsrc:com/demo/dirapitoword/image.jpg">

you need read image stream classpath, e.g.:

inputstream in = getclass().getresourceasstream("image.jpg");

and write stream out file known place on disk. there lots of ways this, if you're using java 7 or above, try:

file out = new file("image.jpg"); files.copy(in, out.topath());

then, src attribute can use relative location chose display image in html, without having worry jar compatibility in browser / client.
