I am sure, I am very late to post reply for this topic.. but still posting for future references..

WAS stores requested URL in a cookie.. if you want to change the redirect value (say to fixed location abc.sxyz), you just modify the value of the cookie in the authentication filter...

Cookie name can be traced.. and its value can also be changed..

I hope this might help someone in future..

Try opening up your admin console for your profile and remove all application from the admin console.

Always remember if you want to remove any application from WAS.. just go thru proper channel.. un-deploy the application from the admin console.. and then delete codebase/application packages.

If server is not coming up at all, you can try using admin commands to un-deploy these application.

Have you configured welcome file attribute in web.xml and verify that path you have given there is actually exists.

Also try hitting some url like http://<servername>:<portnumber>/<ApplicationName>/<ServletName>;

if you dont specify the servlet name, it will see for the file names mentioned in welcome tag in web.xml

also try to look into the sysout log file for your profile.. what doest it say..

Hi All,

I want to code following java code line using tag library:

I need to use logic:equal tag, that I am clear. Here is something which I can think off.. but I know it wont suffice:


Problem is I need to perform some logical operation on property 'processingInstructions' before comparing it, but I am not sure how I can do it with logic tag.

Any help would be highly appreciated.

Thanks.

All,

I am facing one issue with the iteration. Below here is the part of code:



In this BackendRequestItem are being iterated. There is one more collection contained by BackendRequestItem (getBackendRequestItems()[i].getStatus()). I want to iterate over this collection..

If someone can help me out on this, that would be great.

Thanks,

Thanks both of you for your response.

Well my view is also same as you said. Though you may consider HttpServletRequest and HttpServletResponse as implicit object but its not 100% truth.

Anyways I belive there must be some confusion at counter side

Hi All,

Are there any implicit objects available in servlets..? As for my view is concern there are no implicit objects in Servlet.. But in one of interview I faced recently, interviewer asked me this question and when I said there are no implicit objects available he was not agree with me.

Can any one throw some light on it..?

Thanks both of you for your reply.

It means whenever method selection (for overloaded method), is to be done at that time JVM matches reference type of arguement not exact type of that object. Seems a bit strange to me. [:-(]

Anyways thanks for your prompt response.

Hi All,

Have a look at following code:


Output of this sample is 'Hi'.

Can anyone explain logic behind this behaviour?

I was expecting it to be 'Hello' as object passed was actually of Class B but reference holder was of Class A.

Cheers!!

In this way you can surely make subclass of this class.
But to have only private constructor in class will add discussed feature to the class. I hope you will not get confuse anymore. :-)
This means you cannot subclass.
It shows that this class will behave as final class.

I hop you would have gone through my post. :-)
Hi,

class A{
private A(){

}
private static A a;
public A static getA(){
if(a==null)
a= new A();

return a;

}
}

See this class carefully.

You will find
1. No class can subclass this class means it will behave like final class.
2. Only one object of this class can be created tht means only one. (ie Singleton class).

Hopefully it will give you a brief insight of Singleton pattern.

Cheers
Gaurav
