Ok, so here's the deal. Let's take crystal reports for example. I have found out how it works. I have found out that you can build repositories on Crystal reports, you can have them use templates so they all adhere to a certain structure per company stds.
What I could not find out was if there's a way to compare diffrent reporting tools like cognos etc. based on single-sign-on related issues. I also don't know how the comparison would go down in terms of providing some built-in security, something that the rest of the product already does, and it needs to be incorporated in the reporting tool. So for eg. if a user may view only certain types of orders, then that check may alerady be a part of the rest of the product, how would one include it the reporting tool so that every report generated adheres to that constraint.
I also need to know how easy or difficult the integration of the tool would be with std java stuff...
would it be benificial to build a tool instead? What if the requirement is to provide the clients with a tool that is similar to the reporting tool in terms of column selection etc. but the repository that they actually report on would not be a database table directly but an abstraction of multiple tables. How do these tools fare in forcing a user through this abstraction layer, if you will, w/o exposing the nitty-gritty of the database. How do they control the access to the repositories themselves and the formulae. What if there are formulae in the repositories that clients may use, but not modify. I want to know how these tools fare in all of these issues, and whether build a tool may be more prudent, in some cases.

Sorry for the really long post.

Hi,
I wasn't sure where this would go, so I am posting it here.
I want to know how one would go about doing some comparitive study. For example if I was to try to figure out which XML parser would be right for me, where would I look?
Or if I wanted to check out crystall reports, vs. some other reporting engine, where would I look for some comparitive study, or some pointers in a direction to look for would be greatly appreciated.

I know that it ensures, that reading the same field twice should always result in the same value being read except when the transaction itself has changed the value.

But what I don't get is why would one want to read the same data twice, vs. reading it once and storing it in some memory location for future use? wouldn't that be faster?

Also, isn't it emplemented through row-level locking? whereas READ_SERIALIZABLE has table locks right? so does this mean that all Isolation levels really provide is different granularity locking?
Here's the thing. Let's say I have a servlet that aacepts some query from the user and runs it against the database, and if I wanted to allow multiple queries to run simultaneously, I don't need to explicitly spawn a new thread right? When a request is sent to the app server, it will automatically spawn a new thread correct? So all I need to be sure of is that the data consistency issues etc. and synchronization is properly handled in my code. Am I correct in assuming this?

Thanks, that was my gut feeling, that one should not be declaring variables in JSP. But since the mechanism was there, I wanted to be sure.
Thanks!

JSP
Hi our J2EE instructor said that variables declared using JSP Declarations, is not thread safe
so <%! private int hitCount = 0;

goes into the Servlet class during translation but not into the _jspService(). SO it's not threadsafe.
So if that is true, is there a reason why one would want to declare variables that way? and is there a way around it?

JSP
Well good, cause I could manage the slang but not so sure about the sunglasses
I thought so. When I looked up in google, I realized that almost all the job related entries with that term were from that same company

Thanks!

Hi I was looking at this Job opening that said one of the requirements was knowledge of extreme multithreading. What exactly is that?
Thanks

I am in a situation, where because Garbage COllection has not run there is a memory problem. Once Garbage COllection runs, the problem goes away. Is there a way to increase priority on that thread or to somehow specify when to run it?

Well, if that's what I've got to do, then so be it
Thanks for all your help.

James, the interrupt() will work only on a thread that is sleeping or waiting, not on an active live thread
I also took a look at the source code provided by Roseanne.
While that looks really great there is one problem. I do not have exactly a loop, and To check a flag at each and every step(or steps of importence) would make the code look really ugly. I can't seem to find a way out
If only there was a way of throwing an exception in the run, it would have been so useful
any help would be greatly appreciated.
I am coming across the same issue, and I can't seem to find a way to kill a thread :-(
I have a complex code, and to check a flag at all places would be an overkill. Any help would be appreciated.
