MySql Help Needed
Hey all,
I am trying to create a MySQL db to contain song information. I want to create a column for album art (small image of CD) to be displayed with each track. Each track has its own album artwork, so it needs to be dynamic. When creating the db for the songs i have created a field for song_art. My question is: 1.) what type of data field should it be and 2.) how do reference the album artwork from an image file.
Thanks
Matt
if i place all the album art images on the server.. How would i reference them? See heres the thing, this list is going to get extremely long and i need it to be fully automated, the columns are sortable and i need that image to stay with the entry. Is there a way to do this keeping it saved to the disk?
sorry.still new
Matt

I'm a beginner with this PHP/MySQL language, but I'm using
Dreamweaver CS3 to help things along. I've set up my database with
my host (using PHPmyAdmin) and put in a table with some fields.
Then I went into Dreamweaver and set up everything and it saw the
database name perfectly. Then I made a recordset and it saw the
fields just fine. I then made an input page to put the data into
the database and that went off without a hitch. I then made a basic
webpage with nothing but the call to display 2 of the fields in my
database (I did the test in dreamweaver and it saw all the data I
populated my database with perfectly). I then told it to preview in
Firefox and got a blank page... Ok I must have done something
wrong, so I put in some basic text just so I could see if even that
would show up correctly. Then I previewed in Firefox again and not
only did it show up, but the 2 fields showed up as well! Yea! So I
made some changes to the fields I wanted to show and again did a
Preview in Firefox. I was again treated to a blank page. Not even
my basic text was showing up. I went back to Dreamweaver and added
some more text... preview... works perfectly showing everything. I
refresh the page and it's blank. I close Firefox and preview again.
It's a blank page, but for the heck of it I decide to View Source
and lo and behold all the data is there. I close the source and try
reloading the page... blank. I'm at a loss. Any idea why this might
be happening?jays99 wrote:

Sorry, I haven't tested anything on an Intel Mac yet. Testing
everything
on Vista for my new Dreamweaver book has given me enough of a
headache.
However, I'm pretty sure that my editor has an Intel Mac, and
he
followed the instructions in "PHP Solutions" without any
major hiccups.
(They're pretty much the same as in the Flash book.)
Isn't there a MySQL.prefPane icon in the MySQL installation
package? I
have found that MySQL won't start automatically on 10.4 (it
did on
10.3), but as long as you install the prefPane, you should be
able to go
in and start it manually.

Hey Guys... I have a servlet located on the same server as my mySQL database, which is supposed to gather data from the database. Then I have client code, which is supposed to connect to the servlet from some other remote machine, and get the data from the servlet. I had to do it this way because my webhost does not allow remote access to the mySQL database. But my servlet code is not working, no data is being gathered. And I'm betting my client code is incorrect too. I've never had to connect to a servlet from a remote app, I've always connected directly to the database...sooo could you check my code and show me what is wrong and how to do it correctly? (note I XXX'ed out passwords, etc) Thank you...

}Hello kkopacz,
From your code, some of the assumptions seems to appear :
1) You are having Your Servlet Container and MySql on the same machine.
2) You are providing your user name and password in your URL for the MySql Driver.
3) You have mapped the 'ServletTest' class's object by '/servlet/Test' in your Deployment
Descriptor(web.xml).
4) You are assuming at least four records in your MySql database : tsptracker_com [ This should be in fact in your while(rs.next()) loop at least though not checked for rs to be null ]
I would say, try with following changes in your code,
1) insted of 'myConnection = DriverManager.getConnection (url, XXX, XXX);' in ServletTest
only say 'myConnection = DriverManager.getConnection (url)', since you are already giving as a part of dbase URL , uname and pwd.
2) In your ClientTest, try following code
public class ClientTest
public static void main(String[] args) throws Exception
URL url = new URL("http://www.XXX.com/servlet/Test");
// Since http URL and also set content type in response test/html,
// U can use HttpURLConnection object.
HttpURLConnection con = (HttpURLConnection) url.openConnection();
if(con.getContentLength() == -1) {
con.connect();
InputStream in = con.getInputStream();
String buffer = "";
for(int i = in.read(); i != -1; i = in.read()) {
buffer += (char)i;
in.close();
System.out.println(buffer + "");
I hope this should work fine.
Main prob seems to be in your code, is you are giving unmae and paswd again.. and assumption of recod numbers.
Anyway, I think this should work for you.
Cheers

I'm trying to connect to mysql using jconnector on a W2k box. Here are my settings:
Path
C:\Sun\AppServer\jdk\bin;C:\Sun\AppServer\jdk\jre\lib\ext\mysql-connector-java-3.0.14-production-bin.jar
If create a CLASSPATH aswell then I cannot use javac. If I use CLASSPATH with the settings above mentioned the following still applies:
Here is the test prog:
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
public class JdbcExample2 {
public static void main(String args[]) {
Connection con = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
con = DriverManager.getConnection("jdbc:mysql:///test",
"NAME", "PASSWORD");
if(!con.isClosed())
System.out.println("Successfully connected to " +
"MySQL server using TCP/IP...");
} catch(Exception e) {
System.err.println("Exception: " + e.getMessage());
} finally {
try {
if(con != null)
con.close();
} catch(SQLException e) {}
Here's my result:
C:\Sun\Java_Progs\src>java JdbcExample2
Exception: com.mysql.jdbc.Driver
Any ideas?I've just done this:
CLASSPATH:
C:\Sun\AppServer\jdk\bin;C:\Sun\AppServer\jdk\jre\lib\ext\mysql-connector-java-3.0.14-production-bin.jar
But still no luck. I get this:

Any ideas? -
Multiple ethernet network adaptors + MySQL/php5: configuration help needed
I would be grateful if someone could give me some advice on how to configure multiple ethernet adapters under OS X 10.5.6
I have set up my system to work nicely with two ethernet network adapters, each with its own fixed IP. This bit works just fine. The machine supports two separate servers - a mail server and the OS X Apache2 server. I have configured the mail server to only listen to one of the IPs, and the Apache2 server to listen to the other (via httpd.conf). The system also has MySQL and php5 installed / enabled, and these services are only used by the Apache2 server.
The problem I have is that when I start the machine, initially the php5 system cannot connect reliably to the MySQL database system. The fix I have found is to temporarily make the ethernet adapter connected to the mail server 'inactive'. While this is so, the php5/MySQL connection to Apache2 works. Curiously, once an initial connection between php5 and MySQL has been made, subsequently I can make the mail server's ethernet adapter active again without further problems.
I initially thought this might be due to 'service order' issues - but changing the service order (e.g. putting the Apache adapter 'above' the mail adapter in the service order does not help. The fix only works by making the mail adapter inactive temporarily.
I suspect that there is some configuration change I can make to clarify the setup I have. The MySQL and Apache installations only need to talk to the Apache server - but I am not sure how to record this configuration in the OS X system.
Thanks in advance for any assistance that you can provide.

MySQL has run out of memory ::Help needed::
::Help needed::
I've created a PHP web application in Dreamweaver, which uses a MySQL database, containing 14 tables.
On one page, I use a an SQL query to select data from 10 of the tables in the database.
However, when I try to preview the page in a browser, a PHP warning stating that the MySQL engine has run out of memory.
Is there a way of increasing the Memory Cache of the engine, or a way to optimize the performance?Is this happening locally?
If it is, try rebooting your system and see if this fixes the problem. If not then you have a problem with your code. If it works locally but not on the server, then you know it's not something in your code causing the issue, so you can confidently go to your host support and have them sort it out.
With any such situation, testing locally first is a vital debugging step.
Hope this gives you a path to follow.

Help needed for using BASIC authentication through JDBCRealm
Help needed.
Hello,
I am doing a degree project, so far it works fine in my local machine, I need to try it on my virtual hosting (as it is a live server).
My project requires JDBCRealm, that is BASIC authentication loading access data from mysql database. Normally this setup can be done in Server.xml file, because my Tomcat hosting is a virtual one, I only have permission to access the web.xml file.
My question is: is it possible to get it done in an alternative way? In web.xml? Some properties file maybe?
Thank you very much.You can set this up for your context using META-INF/context.xml instead of working with server.xml.
Make a directory called META-INF under your webapp ( it'll be at the same level as WEB-INF ). Under this, add a context.xml with all your context specific configuration including the realm. A sample is below
<?xml version="1.0" encoding="UTF-8"?>
<Context path="/myApp" reloadable="true">
<Realm
className="org.apache.catalina.realm.JDBCRealm"
driverName="com.microsoft.jdbc.sqlserver.SQLServerDriver"
connectionURL="jdbc:microsoft:sqlserver://127.0.0.1:1433;DatabaseName=myDB;SelectMethod=Cursor;"
connectionName="username" connectionPassword="password"
digest="MD5" userTable="users" userNameCol="userid" userCredCol="userpassword"
userRoleTable="user_roles" roleNameCol="rolename"
/>
</Context>Hope this helps.

Help needed to run JSTL 1.1 in Tomcat 6.0.16
Hi All,Help needed to run JSTL 1.1 in Tomcat 6.0.16. I am trying to run the example given in http://tomcat.apache.org/tomcat-6.0-doc/jndi-datasource-examples-howto.html The example tries to connect to MySQL database from JSP using JSTL and JNDI Datasource.I am running the example using Eclipse 3.4.2 using Sysdeo plugin to start and stop Tomcat server from Eclipse IDE.
My web.xml file has <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">
</web-app>
and test.jsp has proper taglib directives
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
I have placed the jstl.jar and standard.jarof the jakarta-taglibs-standard-1.1.2.zip under E:\Deepa\workspace\DBTest\WebContent\WEB-INF\lib directory also placedcontext.xml file under E:\Deepa\workspace\DBTest\WebContent\META-INF and the content of context.xml is as below
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"

username="deepa" password="mysql" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest?autoReconnect=true"/>
</Context>
Now while running the example, Eclipse creates one DBTest.xml file under C:\Program Files\Apache Software Foundation\Tomcat 6.0\conf\Catalina\localhost
which has the following line:
<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest" workDir="E:\Deepa\workspace\DBTest\work" />

When running the same example, by creating a local server in Eclipse(creating new Server connection pointing to same Tomcat 6.0 installation) it runs fine without any error.Hi evnafets,
Wow, very helpful information, great insight into working of Eclipse. Thanks a lot.
I have one more question. I have a context.xml file under {color:#0000ff}E:\Deepa\workspace\DBTest\WebContent\META-INF{color} folder and that has the Resource element to connect to MySQL database:

{color:#0000ff}</Context>{color}As usual when running application in local Tomcat server of Eclipse, this data source works fine. But when I run the application on Tomcat, by starting Sysdeo plugin from Eclipse, the DBTest.xml file created in C:\Tomcat 6.0\conf\Catalina\localhost has the context entry as<Context path="/DBTest" reloadable="true" docBase="E:\Deepa\workspace\DBTest\WebContent" workDir="E:\Deepa\workspace\DBTest\work">

Having trouble with SQLServer 2008 (not MySQL) and my database connection in Dreamweaver CS6. My document type is set as .asp using VBScript. I can list the table information but cannot use the insert wizard to add new records. I don't get any errors after creating the insert form, but no records get inserted. I'm not a VBScript expert, but do I have to manually write some code to insert records? How do I attach it to a button?
Thanks for the quick reply. I won't be back in the office for a few days, but I'll try to post it when I get back in. It's pretty much the code generated from the Dreamweaver Insert Record wizard. I see where the submit button is created and the value is set but the action on the form is set to MM_insert, so I don't see where the submit code is actually called.

good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --PradeeshWell I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say. -

Hi all help needed I have a canon 40D. I am thinking of buying a canon 6D.
But not sure that my lenses will work.
I have a 170mm/ 500mm APO Sigma.
A 10/20 ex Sigma HSM IF.
And a 180 APO Sigma Macro or do I have to scrap them and buy others.
ALL Help will be greatly received. Yours BRODIEIn short, I love it. I was going to buy the 5DMark III. After playing with it for a while at my local Fry's store where they put 5DMII, 5DMIII and 6D next to each other, using the same 24-105L lens, I decided to get the 6D and pocket the different for lens later.
I'm upgrading from the 30D. So I think you'll love it. It's a great camera. I have used 5DMII extensively before (borrowing from a close friend).
Funny thing is at first I don't really care about the GPS and Wifi much. I thought they're just marketing-gimmick. But once you have it, it is actually really fun and helpful. For example, I can place the 6D on a long "monopod", then use the app on the phone to control the camera to get some unique perspective on some scenes. It's fun and great. GPS is also nice for travel guy like me.

Help needed! Raid degraded again!
Hi!
Help needed! I hava made bootable RAID with two S-ATAII 250Gb HDD and its not working! Every now and then at bootup I get a message RAID -> DEGRADED... Must be seventh time! Rebuild takes its own time!
What am I doing wrong!
T: Ekku
K8N Neo4 Ultra
AMD 64 4200+
2 Gb RAM
2 x 250 Gb HDD (Maxtor)
nVidia RAID (in mb)
P.S. I wery SORRY with my poor language!I'm going to blame the nVRAID because I've seen issues with it in the past. If your motherboard has another non-nVidia RAID solution, use that instead. Using the nVidia SATA ports as BASE or JBOD is fine and dandy but RAIDing always had issues. It's not even a driver issue I think it's just instability. Latest drivers and even boxed drivers never helped. Granted, some will report success with their rig. But on a professional level I've seen nForce issues on different motherboards and different hard drives that had RAID disaster stories.
Good luck and if you don't have another RAID solution, my suggestion would be to buy a dedicated RAID controller card.

Get over it mate !
I find it easy t read CAPS...and if you dont like it ...DONT READ IT!
And why bother to reply...some people have nothing better to do.
Yes there chep and easy to come by...Ive already got a new one.
All I wanted was to make a diagram of whats inside the bloody thing...it was a simple question and required a simple answer.
NO NEED TO A WANKA !!
I feel a bann comming up.
Have you tryed Google ? really.. your question is inrelevant. No need to reply indeed.
Why do you come here asking this question anyway ? is it becouse you have a MSI gfx card ? and the adapter has nothing to do with this ?
You think you can come in here yelling.. thinking we have to put up with it and accept your style of posting. This is not a MSI tech center.. it's a user to user center.. Your question has nothing to do with MSI relavant things anyway's.
Google = your friend.
