Just wondering, when did Sun changed from 72 question format to 60 questions total? I believe passing remains same as 58%.

Hi all,
I am using WSAD5.1 and DB2 UDB7.2.
db2 driver path is: c:\db2client\SQLLIB\java12\db2java.zip

When I run one of my client apps(ejb,classes) some of the classes are calling stored procedures then I get the following exception on my wsad test server console:

com.bis.common.base.MyException: Base executeCallableStatement() failed.:
[IBM][CLI Driver][DB2/NT] SQL1109N The specified DLL "DB2I..my_stored_proc" could not be loaded.

I am getting this error only when a program trying to call stored procedures other than that it is fine retrieving the database records and stuff like that.

WSAD DSN for driver and JNDI mapping looks good to me...I tried to re install my db2 client but still same problem...
Would you guys please help me in this regard....that am I missing anything to configure in WSAD or DB2???

there is no need to use any componenets for creating calendar functionality.sheduling and reminders are must and should use stored procedure concept.and calendar you can use logical program

But my database is MySQL which I guess does not support stored procedures..right??

Can you guys shred some light, how we do accomplish the calendar functionality like outlook in the web application. Like add events, scheduling, re occurrence of the events using jsp, servlets and database.. Is there any component that we can use of it for this purpose.

On the one hand you seem to have made a lot of technical decisions (please explain how/why you have already chosen JSP, Tomcat, MySQL and NetBeans, for example).

--> Because they are all free/open source..costs or less money

On the other hand, you tell us nothing at all about what the application is actually supposed to do! For you or us to try and make any design decisions or offer advice without knowing what is being designed is a sure road to misunderstanding and probable failure.

--> This is just Web application 100 or so concurrent users..may be less then.. not known at this time..

All we know about the application so far is that it has a web interface. I'm guessing this means a HTTP interface, rather than applet(s). The only sensible way to "talk" HTTP from Java is using servlets, so your solution will likely involve one or more servlets.

--> Yes, you are absolutely correct.. no applets..

How you produce your servlet(s) (hand written, or produced using code-generation tools such as JSP etc.), how you produce the HTML for the web pages (JSP, custom tags, templates, raw HTML in Java etc.), and how you manage the interaction between the HTML data and the "business logic" is still open.

--> Servlets are going to be hand written.. for the web pages I will be using JSP's. I wanted to use the Conroller Servlet to call the appropriate class/bean to make the data base calls.

I'm particularly worried that you seem to be leaping to potentially complex solutions (JSP, struts, XML, EJB etc.) with no evidence of need. I'm also having a hard time imagining a system that really has 70-100 entirely different kinds of pages and how you plan to make a usable, testable and maintainable application using this approach.

-->Yes you are correct... I might over stated the pages.. they might be around 50+ jsp's and htmls collectively..not sure though.. wanted to make jsp's as simple as possible..

Please tell us more about why you have made the decisions you have so far, and some idea of what this application is for, in real customer terms. Thanks.

--> I haven't made decision so far.. wanted to use struts (advanced tech..)...to reduce more scriplets in the jsp and make use of JSTL... this is just a typical web site... not involed any critical data processing..just data retrieval to web page and data posting to database..not many concurrent hits..looking for portability for future migration to different database or different app server not yet known...can't able to give more specifics..This site is not for commercial usage though..hope this helps!!!
Give me some broad ideas for design standards..
Thanks.

Hi,
I have a small to medium range web based project(product) to design... I need your help to design the project using best, advanced practices in our Java community..
Here are the expected static's and environment of the project.
1) 100 concurrent users..possible increase in the long run..
2) 70 to 100 JSP pages for presentation possible increase..
3) Moderate user interaction with the forms (not so much complicated...)
3) Tomcat server, MySQL database, Linux environment.
4) NetBeans IDE with Java1.4 and Poseidon UML tool..
Would you guys please provide me some help in designing the system using latest Java technologies..since I am new in designing..
I have some ways in my mind using MVC..I wanted to use XML and Struts must be in any design... correct me if I am wrong..
1) Using Servlets, JSP, Struts, XML ... how feasible this way??
2) Using Servlets, JSP, Java Beans, XML
3) Using EJB, JSP, XML
any issues, pros,cons and online resouces will help!!
Thanks a bunch..

Hanumanth,
1) To pass this exam, what shold be the level that one should have in related subjects?
2) How your book helps to reach that lever?
3) What are the required topics needed to this exam and is your book covers all of those?
Thanks,
Srini.
