replace - How to use the new image replacement technique by Scott Kellum -

i practicing using various image replacement methods , came across couple articles discussing new, supposedly more efficient method scott kellum. original website article regarding new method it seems , practice using it, not sure html , css should be. in example below, have h1, example logo text inside. added class of .hide-text h1 , styled css. used photoshop logo image made , set background image....the image has width of 203px , height of 57px. question 1: when tested code in browser, seems working fine, usage of mr.kellum's image replacement technique correct? question 2: should target h1 in css , declare width , height or okay include width , height directly in hide-text class in example below? <style> .hide-text { background: url(images/mylogo.jpg) 0 0 no-repeat; text-indent: 100%; white-space: nowrap; overflow: hidden; width: 203; height: 57px; } <body> <h1 class="hide-text">mylogo text</h1>

java - Axis - Response class extends AxisFault and is thrown instead of returned? -

i have generated java class files using axis1 (axis-1.4.jar). have ws method call (i can see generated java code too). say method call accepts requesta parameter , returns object of type responsea. problem have responsea extends axisfault (i can see in generated java source file responsea). axisfault on own turn extends remoteexception. as result of this, responsea object returned not returned me thrown to/at me remoteexception. so when this try { responsea x = call(y); // y requesta } catch (exception ex) { ex.printstacktrace(); } in client code, flow of control goes catch block , catching should getting in x variable (i.e. ex x be). any idea makes axis generate responsea class subclass of axisfault? also, in general, when class generated axis, generated subclass of axisfault? i think current problem. think in weird situation response succesful ws method call not returned me instead thrown to/at me. many in advance. package com.test.fulfillme
