I dont think I can understand your reply. I am able to understand the sections from the sun's website. From where did you get the

"the specification core, persistence e simplified wich makes a EJB 3 Specification."

Thanks
Sri

What does the section refers? Are they the objectives given in the sun.com website

Which book you are referring here? Even I am looking for something like this

Sorry not sure about the exact forum to post this question.

a specified period of time or when I log in for the first time. when I try to re login immediately after I get this exception it works fine. The environment I am running my application is

unix platform
tomcat 6.0.18
mysql 5.0.67
mysql-connector-java-5.1.7-bin is the jdbc connector I am using.


My connection pool defined in tomcat context.xml:


<Resource name="jdbc/MYDB1" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="root" password="xxxx" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/mydb?autoReconnect=true"/>
I have set the permission:

view plaincopy to clipboardprint?

1. GRANT ALL ON mydb.* TO 'root'@'%' IDENTIFIED BY 'xxxx';

GRANT ALL ON mydb.* TO 'root'@'%' IDENTIFIED BY 'xxxx';

And When I execute

view plaincopy to clipboardprint?

1. Show Create Procedure mydb.myproc;

Show Create Procedure mydb.myproc;

I am able to see the entire body of the procedure.

And one more point is I get this exception only when i run my application on my remote server which runs on unix platform and not on my local machine which runs on windows.

Any help or suggestion would be appreciated.

Thanks

Hello ranchers

I am new to struts and I have zero knowledge about it. I recently finished my SCWCD 5.0 certification. Can anyone suggest me good book for understanding struts 2.0 and which has practical examples. There are many books in the market so I dont know which one to buy. So please help me.

Thanks
Srividhya

I practiced for 2 months. I think SCJP questions were more tricky. Here are my scores....

Whizlabs

86%
75%
71% - Fail
75%
76%

Enthuware

91%
81%
90%
86%
87%
91%
86%

And I took marcus green mock exam, javabeat and Peabody Design Pattern notes.

Srividhya

I studied HFSJ then took whizlabs and enthuware mock exam. Enthuware mock exam was more helpful. Thats all.

Srividhya

Hello ranchers

Thanks for your support. Today I cleared SCWCD exam with 94%.

Cheers
Srividhya

Thanks christophe. These questions are from HFSJ mock exam 2nd edition. Is there any errata for this edition.

And I have a doubt in a topic not related to this post. Can a request dispatcher be used to forward a request to a file in another web application. I am taking my exam tomorrow so in a hurry. Sorry.

Srividhya

Hello ranchers

Is it valid for more instances of <auth-constraint> to exist within the single <security-constraint> tag?

Srividhya

Given:
1. <%@ taglib prefix="c" uri="http://java.sun.com/jsp/
jstl/core" %>
2. <%@ taglib prefix="tables" uri="http://www.javaranch.
com/tables" %>
3. <%@ taglib prefix="jsp" tagdir="/WEB-INF/tags" %>
4. <%@ taglib uri="UtilityFunctions" prefix="util" %>
What about the above taglib directives would cause the JSP to not function?
A. Line 4 is wrong because the prefix attribute must come before the
uri attribute.
B. Line 3 is wrong because there is no uri attribute.
C. Line 4 is wrong because the uri value must begin with http://
D. Line 3 is wrong because the prefix jsp is reserved for standard actions.

Correct answer: C. I think option C is wrong and right answer should be option D. Help me to find the correct answer.
