MySQL & Tomcat Integration Help

Are there any good samples for using MySQL with Tomcat (JSP or Servlets). I installed Tomcat, MySQL and Connector/J and looking for some sample code....
Help on where to start would be appreciated.

Getting JNDI not found on MySql/Tomcat

Has anyone gotten ADF to work with MySql/Tomcat? I think I finially have the app working in Tomcat but now I'm getting an error with my pool/JNDI lookup. At the tomcat console I get this;
SEVERE: Null component Catalina:type=DataSource,path=/ediweb,host=localhost,class=javax.sql.DataSource,name="jdbc/ediconnDS"
It looks like it can't even create a connection to MySql. My app has a context.xml in the META-INF like this;
<Context>
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<ResourceLink global="jdbc/ediconnDS" name="jdbc/ediconnDS" type="javax.sql.DataSource" />
</Context>
And in my server.xml I have this;
<Resource name="jdbc/ediconnDB" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000" username="root" password="password" driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/freightedi"/>
In my web.xml I have this resource-ref;
<resource-ref>
<description>DB Connection</description>
<res-ref-name>jdbc/ediconnDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
I've tried putting the resource in the context.xml... all kinds of stuff, to no avail.
I tested these connection parameters in Squirrel SQL (java jdbc based SQL tool) and it works?!
Please help :(

Integrated help in Visual Studio

I installed ODP.Net into Visual Studio .Net 2003. Is there any way to integrate the help from ODP into Visual Studios help? I would to get the same type of response when I press F1 for a OPD member as I get for the normal .Net classes.
For instance:
string f = String.Format("00", 1);
If I put the cursor in the word Format and press F1 Studio will show the help for the String.Format Method
If I do the same for a method in any of the ODP classes only the Index for Dynamic help is displayed.
Have I forgotten to install something or is there something else I have missed?
/per

Hi,
Finally someone discovered the integrated help...
1) You have all the namespace imported properly? Add the Oracle.DataAccess.dll as reference?
2) Make sure you have only 1 version of ODP.NET help (check the Add/Remove Program). If not, remove all old version and reinstall ODP.NET
3) For VS.NET 2003, in the case where ODP.NET help is not registered (e.g. you don't see the book in the content section, search OracleXXX only returns MS's doc etc), do this:
Dynamic Help (press f1) -> Installing Help for Visual Studio -> Visual Studio .NET Combined Help Collection Manager -> check ODP.NET help and update. Restart studio.
This is a limitation of the help registration process for MSHelp2 system.

I have downloaded MAMP for Mac and want to use it for working with Wordpress. I had mysql installed before this and would like to uninstall it and use MAMP. It was easy to turn off Apache and PHP but don't know how to uninstall mysql. Please help!!

I have downloaded MAMP for Mac and want to use it for working with Wordpress. I'm on an Imac with Maverick OS 10.9. I had mysql installed before this and would like to uninstall it and use MAMP. It was easy to turn off Apache and PHP but don't know how to uninstall mysql. Please help!!

It depends on how you installed it. You have to shutdown the MySQL service first. If you used the standard, but obsolete Startup Item, you can do that with the Startup Item. If you created a launchd script, you can do it with launchctl. Once MySQL is no longer running, you can delete the Startup Item or launchd script and the rest of MySQL.

you have your driver jar in Tomcat\common\lib?
if so, check your classpath, it could be that.

I had the same "is not a known entity type" error when running under a development environment Eclipse/Tomcat using Toplink. But the almost same code and configuration worked when running under Eclipse as a stand-alone Java app.
Eventually I figured out (actually trial and error), that I had checked the toplink-essentials.jar libraries to be exported under: Eclipse Project/Java Build Path/Order and Export. I was messing around with libraries. Unchecking the export option there fixed the problem.
While its unlikely that this could have been your exact problem, I would check the library order and export configurations. Looking at other message boards about this problem, many seemed to have been caused or fixed by playing with their libraries.

Ergent problem with the jsp file access in tomcat. HELP...

I use tomcat as my server, I have one JSP file located in :
webapps\abc\war\WEB-INF\jsp\index.jsp
You see my project name is abc, I want to access the index.jsp file, I define another jsp file in the path: webapps\abc callled outside.jsp. I want to use outside.jsp to invoke the index.jsp.
Inside outside.jsp it is :
<html>
<head>
<title>index</title>
</head>
<body>
<%@ include file="war/WEB-INF/jsp/index.jsp" %/>
</body>
</html>
When I open the browser, and access, http://localhost:8080/abc/outside.jsp , the content of index.jsp was shown as expect. But, all the link pages of the index.jsp can not shown (PS: the link pages is located in the same path as index.jsp, they are all jsp files). I guess the problem may be that the <%@ include file="war/WEB-INF/jsp/index.jsp" %/> inside outside.jsp include the index.jsp as a static file. Is there any method to make all the link pages of index.jsp can be shown when call from outside.jsp???HELP

I don't know why your links can't be shown, but I can tell you that your suspect:
I guess the problem may be that the <%@ include file="war/WEB-INF/jsp/index.jsp" %/> inside outside.jsp include the index.jsp as a static file.is wrong, because included jsp is dynamic, not static.

I need to learn how to use all about java & mysql...help me!

I have a situation here, I need to learn how to use java with mysql
. Can I connect to a MYSQL DB with servlets?
how can I build an e-mail server with java (no matter how difficult)
please, I need help, and I really apreciate your help.
thank you very much!!

I have a situation here, I need to learn how to use
java with mysql
. Can I connect to a MYSQL DB with servlets?Yes... documentation to help you connect to any database can be found at http://java.sun.com/products/jdbc. To connect to MySQL, you'll need drivers (sourceforge.net), and the specific connection URL for those drivers will be included in the documentation.
how can I build an e-mail server with java (no matter
how difficult)If you're fairly new to JSP/Servlets, you may be in over your head here, since an email server is no easy application to code. Here's a link to the source code for the JAMES project... Apache's Java email server... maybe you can find some useful information there...

Character Setting Problem ( mysql + tomcat )

Hi all;
I am using mysql dbms and tomcat web server(servlet). But in my web page, the characters are shown broken. I set the character set of the mysql database. They are shown well in the dbms console. And also I set the html code with appropriate character set in the meta tags. Do I need to make any extra setting? Perhaps in the tomcat or anywhere else? What is the problem here?

assumes:
1. using jsp to display the db data
2. db encoding is ISO-8859-1
3. jsp encoding is utf-8
for the very first line of the jsp file:
<%@ page pageEncoding="utf-8" %>before displaying the data:
String str = <data from db>
str = new String(str.getBytes("ISO-8859-1"), "UTF-8");

Get a copy of your ldap server's public certificate. Use keytool to import (and create) that cert into a truststore. Configure the ssl props to use the new truststore.

FILENOTFOUNDEXCEPTION while reading property files in Tomcat 6------Help me

Hi All
I am planning to migrate my web application from iplanet 4.1 to tomcat 6. In this process I need to read the properties files initially.
for eg: i got the property files in a iPlanet:
Config directory---
abc.properties.---
abc.log--
In tomcat I configured them in web.xml saying that.
<servlet>
<servlet-name>ABC</servlet-name>
<servlet-class>com.ijk.abc</servlet-class>
<init-param>
<param-name>Loan</param-name>
<param-value>/WEB-INF/config</param-value>
</init-param>
<init-param>
<param-name>loan.props</param-name>
<param-value>/WEB-INF/config/abc.props</param-value>
</init-param>
<init-param>
<param-name>loan.log</param-name>
<param-value>/WEB-INF/config/abc.log</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ABC</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
I need to read initially all the property files and then proceed.
While configuring in this way, it am getting error saying that
abc.props or abc.log..............(FILE NOT FOUND EXCEPTION)
Can anyone suggest me how to configure them.
Thanks in Advance.

Thanks for your response, Actually we dont have the source code for that because it is very old code, but i m using decompiler in which i can get some informtaion.
OS used for iPlanet is Unix but now I need to deploy this application in tomcat in windows server 2003.

the above is the servlet class and the method which is using to read the property files from root directory in Unix.
ie../opt/mywebapp/loan/abc.props,abc.log
loan is the directory in which two property files are placed.
i just want to where to place property files in tomcat so that its going to read the property files.
Right now, i placing it in the WEBAPPS/MYWEBAPPLICATION/WEB-INF/LOAN/abc.props,abc.logs.
Its giving me errors such as FILENOTFOUNDEXCEPTION or cannot read the property files.
The main problem is ...I donot have the complete source code. while decompiling i m not able view complete source code.
Please help me regarding this.........
Thanks in advance.

MySQL Select Statement Help Required

I am trying to generate a report in VS 2008 (C#) using a mysql select statement but cannot get it right.
I have groups that meet on a weekly basis on different days. I want to generate a report that shows me all the members that have not attended their group where they have missed 3 meetings in a row.
Below is the select statement I have tried but it does not give me the results I am looking for. I have tried to look at all the meetings in a 4 week period but would prefer to look at the last 3 meetings that are recorded. Some groups might not record a meeting every week. So I want to look at the last 3 recorded meetings and count each members attendance and only report on the members with more than 3 meetings missed.
SELECT COUNT(`groupattendance`.`Attended`) AS Attendance, `smallgroupform`.`MeetingDate`, `userinfo`.`FirstName`, `userinfo`.`Surname`, `smallgroup`.`GroupName`, `groupattendance`.`Attended`, `groupattendance`.`UserID`, `groupattendance`.`GroupID`
FROM ((`anatomy`.`groupattendance` `groupattendance`
INNER JOIN `anatomy`.`smallgroupform` `smallgroupform` ON `groupattendance`.`FormID` = `smallgroupform`.`FormID`)
INNER JOIN `anatomy`.`userinfo` `userinfo` ON `groupattendance`.`UserID` = `userinfo`.`UserID`)
INNER JOIN `anatomy`.`smallgroup` `smallgroup` ON `groupattendance`.`GroupID` = `smallgroup`.`GroupID`
WHERE (`smallgroupform`.`MeetingDate` >= DATE_SUB(CURDATE(),INTERVAL 4 WEEK) AND `smallgroupform`.`MeetingDate` <= CURDATE()) AND `groupattendance`.`Attended` = 'False'
GROUP BY `userinfo`.`UserID`
HAVING Attendance >= 3
Thanks,
Garth.

Hi Garth,
Seems no one can help you directly. Try googling your SQL request. Someone may be able to help you. At this point its not really a Cr problem.
One option is to get all the data and add filtering using the record selection formula.
Thank you
Don

Wierd performance in tomcat/java: help consult

hello
after to test my project in tomcat 5.5.23 and jdk 5 update 12
in network(intranet-only until now with 2 clients) i see that this is fast, after of a some time i can see a wonderful exception
related with java heap exception thrown by the tomcat
after to search in google, i found the solution for windows
(server works with windows XP SP2) related to give some values
for memory ram values to the tomcat5w.exe
http://computerlabsolutions.com/supp...hp#performance
i only did the second step
according to this
>
Click on the Java tab, and enter 128 in the Initial Memory Pool, and 350 or 400 in the Maximum Memory Pool.Leave the other field blank.
so my values are
128 in the Initial Memory Pool
400mb Maximum Memory Pool
the point is that the server is a intel dual core with 3ghz for each , and has DDR2 512 MB of ram
ok, its works, the point is that after to restart the server, the system is fast again,
but then again after of some time the performance go to very slow
if i do ctrl+ alt+ del to see the performance of the pc related with the ram
i taked a picture when start the wierd performance
my ram go to 645MB and swap 46200KB
i thought if i stop to use the system/application(5 minutes),
i can give the chance to the java or tomcat to get and free
some resources
well not the ram go to 640MB and swap to 45276KB
of course if i shutdown my tomcat
i have now these values
RAM 319MB and swap 44564KB
is normal this?,
i dont think so
some important suggestion/advice by our members??
BTW: i am using pool connections related with the db area
thanks so much for advanced

I suspect you are paging. You've allowed the Java object heap to grow to 400MB, but you need physical memory for other things (the executable, thread stacks, the operating system, etc.) I think what you are seeing is that performance is good until you start to page the Java virtual machine, at which point performance probably hits a wall. And having things slow down can cause queues to back up, retransmissions to happen, etc, increasing your memory load and making things worse.
Either buy more memory, or try tuning that 400MB down to a level that your machine can sustain. If you have GC logs, you can tell how much live data you have, which could help you choose an appropriate value for the maximum memory pool.
