My doubt is

In real time , If we need to devlope a JAX-WS webservice ...do we need to generate these supporting binding files and wsdl in commnd prompt by using Wsgen tool and moves those files to corresponding location of eclipse and follow the next steps to devlope complete web service or Is there any other way it will be devloped in real time like tool will l generates these supporting binding files and wsdl automatically rather than command prompt ?

Hi Everybody can someone provide me the Java code for converting seconds into Days ,Hours and Minutes




for example


1 Day 2 Hr 20 Min =24*60*60 + 2*60*60 + 20*60= 94800 Seconds

Similarly if we input 94800, the output should be 1 Day 2 Hr 20 Min

Hi All ,

Please someone provide the javascript code for validation of a input number .


Conditions -

If we input like 0005 ,it should throw error ,but if we input 5 it should not throw any error (It means zeroes are not allowed before any number) .


If we input 0,it should not throw any error (Single zero is allowed ).

It will be very helpful if someone provides validation code with checking zeroes from the beginning with the help of Regular Expression
