Dreamweaver MySQL recordset connection problem

Hi,
I'm trying to create a recordset for the first time in
Dreamweaver MX but am having problems getting the connection with
the database to work.
I have set up a MySQL database on my server (which I have
checked and is OK), checked that PHP is running and have connected
Dreamweaver to the server successfully ( in "Edit Sites" the
"remote info" & "testing server" tests show a successful
connection).
When I try to connect to the database I get this sequence of
events:
1. Dialigue box: "Retrieving information from public_html"
2. Dialigue box: "Waiting for server" (with progress bar)
3. Dialigue box: "Dreamweaver cannot determine the remote
server time. The Select Newer and Synchronise commands will not be
available."
4. Spinning ball for a few minutes (I'm using Mac OSX)
5. back to "Waiting for server" dialogue box which remains
for ages, eventually I click "cancel"
6. "An unexpected error occurred"
If anyone can shed any light on what I might be missing I
would appreciate it greatly.
Thanks - Zaphodz

I am a newby to databases and am having a similar problem
with asp and my remote sql database. My hosting provider told me to
use this script:
<%
Dim DBName,DBUser,DBPass,objRS,objConn
DBName="cham_members"
DBUser="cham_member"
DBPass="mypassword"
Set objConn=Server.CreateObject("ADODB.Connection")
objConn.ConnectionString="DRIVER={MySQL ODBC 3.51
Driver};Server=localhost;Database="&DBName&";UID="&DBUser&";pwd="&DBPass&";"
objConn.Open
Set objRS=Server.CreateObject("ADODB.Recordset")
%>
Since that code doesn't work with DreamWeaver's Databases
panel Custom Connection String dialogue box I came up with this
one:
DRIVER={MySQL ODBC 3.51
Driver};Server=localhost;Database=cham_members;UID=cham_member;PWD=mypassword;objConn.Ope n
Set objRS=Server.CreateObject(ADODB.Recordset)
It connected but doesn't show my tables. I followed all the
advice I found here;
1. Connect using the "Use passive FTP"
2. Corrected a few illegal hyphens in my database.
3. Tried MySQL 127.0.0.1:3306 which would not connect at all
4. Remove Connection Scripts. No change.
5. I have been running DreamWeaver 7.01 update.
I noticed the database connection names come up in the
"Connections" folder so I opened the file it had just created and
pasted in the script my hosting company gave me. Still no luck. I
am determined to learn to create dynamic websites so I really
appreciate your help.
Thanks, Ann Y.

Mysql, Jboss connecting problem

Hello,
I am having problem with mysql database. I am trying to run AccountEJB application from SUN with mysql as my backend.
PLEASE DO NOT FORGET I AM NOT EXPERT IN JBOSS OR EJB BUT I AM TRYING TO LEAN WITH A EXAMPLE.
HERE IS MY SETUP UP TO THIS POINT.
I am running jboss-3.03.0_tomcat-4.0.3
I am including
1. AccountBean
2. ejb-jar.xml
3. web.xml
4. jboss.xml
6. mysql-service.xml ( I add my database name, username, password and i copy it to ..server/default/deploy dir.)
I only modified mysql-service.xml. Do i have to modify any other jboss files. Some people are saying i have to modify "standardjaws.xml, standardjbosscmp.xml"
My AccountBean code is
Please take a look at "setEntityContext" and "makeConnection" that is where problem comes.

Running a CMP EJB with MySql DB Connection Problem

MySQL database connections problems !!!!!

Hello there,
I hope someone could light the way lol
i'm new to php and i was hoping that DW CS4 could help me with most of the code but...... i can't even connect to MySQL....
DW doesn't seem to be able to see MySQL 5.1 and i have PHP 5.31 ... my server is IIS 7.5 on windows 7 ultimate,,,,
IIS/MySQL/PHP are all running fine i cant test them with hand coded *.php page so the only conclusion i have is that DW CS4
is not compatible with my set-up...
so my question is which version of MySQL and PHP do i have to use ???
I would prefer not to use appache but iff i have no choice.... (took me 2 weeks to configure lol)
Thx
Webgau

Have you uncommented the "extension=php_mysql.dll" line under DYNAMIC EXTENSIONS in your php.ini file? Does the MySQL module show up if you run <?php phpinfo(); ?> ?

MySQL Localhost Connecting to Dreamweaver Issue

Hi,
I have just iinstalled and set up MySQL v5 on OS X 10.4.3.
I am using CocoaMySQL as a GUI to add / edit tables and data, this works fine as when I connect to MySQL and a database I don't have to enter a password. I use the following settings...
host: localhost
user: root
password: <empty>
database: test
Everything else is empty.
This works fine. But when I use Dreamweaver 8 to connect to MySQL I get issues. I use the following settings...
Connection name: test
MySQL server: localhost
User name: root
Password: <empty - don't have one>
Database: test
I have also tried using 127.0.0.1 as the MySQL server address.
I get the following errors when I try to test connect the connection...
"HTTP Error Code 404 File Not Found"
So it can't find the MySQL connection? and it brings up an error when I click 'OK' saying that I should have a password.
I think the major issue is not being able to connect in Dreamweaver when I can connect in CocoaMySQL!
Anybody out there got any ideas?!?!

Hi,
I had the same problem, and I think that you should use your public ip to connect to mysql.
I think that this problem comes for some dns issue on which I'm working on.
Try to connect to your server using mysqladministrator you can download for free at mysql.com to see the root privileges or to connect to your mysql daemon using terminal with mysqladmin -command utility.
Read my post about mysql 5 maybe you will find some interesting things...
Good Luck

PHP and MySQL Connection problem

I am trying to make a PHP MySQL on a remote server connection in Dreamwesaver CS3.
When I enter the information (host, user, password, etc.) and hit TEST, I get the following error message.
"Access Denied. The file may not exist, or there could be a permission problem. Make sure you have proper authorization on the server and the server is properly configured."
I know the user, password, etc. work, as I can access the MySQL database with other software.
I checked with my host and they say there are no permission problems on their end.
I have checked the settings on the Test Server page in Site Setup and everything looks correct and works there.
I have not seen this particular problem described in other forum postings (although there are a LOT of postings on this topic!).
Any help would be appreciated.

I thought my testing server was the remote server and is always on as far as I know. I don't know how to turn it on or off.
Is there some other testing server that I should be aware of?

I know you are using remote, but is your testing server on? if not turn that on and see if that does it. it just happened to me working on remote server and could not get mysql conn to work, until I turn on my testing (developer server), then I was able to connect to mysql and the tables that I created in phpmyadmin remotly was downloaded.

DW CS3 to MySql connection problem

I have DW CS3 on Windows Vista. I have installed the Apache
web server and MySql. I've associated the Apache server for testing
and it works fine for page displays, so when I make a change to a
page and hit F12 it is uploaded to the test environment and
displayed in a browser.
MySql is up and running, I can log onto it with the MySql
admin client and see my database (just a testing one).
When I try to test the sql connection I get the message "An
unidentified error has occurred" and I don't have access to the
data.
When I try to test a PHP page it is treated as a file object
and not processed, just loaded for editing.
I don't know what I've set up wrong, any help
appreciated.

Was this issue resolved?
I have the same problem now. DW was working fine the one day and the next when I started it it had this connection problem.
I am testing on my local PC. My sites is at http://localhost/
All my connection are working because if I go to http://localhost/index.php I can see my site and if I go to http://localhost/register.php I can even register a new user. It will include the new user details in the data base and everything is working fine. So there is nothing wrong with the connection.
In DW I do have http://localhost/ on the Local Info screen. As I said, all was working fine on the current setup the one day and the next day it did not want to work.
Seems like a very common problem.
I want to buy CS4 and surely hope that the problem has been fixed by now.

DW CS4 MySQL Connection Problem

I know this one has been covered before but i've been trawling through posts for the past 2 days and still haven't solved my problem.
I remember from using MX Studio and Ultradev that setting up a connection could prove challenging. It seems that CS4 is just as user-unfriendly in this regard. I know that the settings i'm using for the connection must be correct as i'm using them to successfully connect to the database and display its records using a hand-coded page. I've tried disabling Kaspersky and Windows Firewall but to no avail. I noticed one difference between the php script that dw attempted to make and mine is that i'm using mysqli whereas the dw version just refers to mysql. When I click on the Select button to try and select the database i just get "An unidentified error has occurred" - about as much use as a chocolate fireguard - well done to the dw development team for that pearl of wisdom. Is dw trying to find my databse somewhere where it's not located? I noticed that C:/InetPub and its subfolders are marked "read only" but when you uncheck this, it reverts to read only - i don't know if this may have something to do with my inability to set up a connection. I managed to manually set up MySQL, PHP and Apache without problems but this has got me beat. Is it bad design in dw or am i just stupid? Don't answer that! Any help would be greatly appreciated as i know there's a lot of good stuff in dw if i could only make a connection (and i'm on a 30 day trial with this) Why should something that looks so easy be so difficult! Thanks, Mark

Hi PZ,
You're correct! I just managed to get my connection to work. I looked in my php.ini file and it only had extension=php_mysqli.dll at the bottom of the page (the dll file to which this refers was in the ext folder). So, I just added extension=php_mysql.dll to the end of the php.ini file then downloaded the PHP 5.2.13 zip package from http://www.php.net/downloads.php and then copied the file php_mysql.dll into the ext folder. I got the clue about mysqli not being supported after i'd carried out a Site > Advanced > Remove Connection scripts - that at least gave me a message "Your PHP Server doesn't have the MySQL module loaded or you cant use the mysql(p) connect functions" - before i did this i just got a useless "An unidentified error has occurred" which left me no further forward. Thanks for your help!

Hi!
You can try with this code coz, i worked with this code only and then i can talk to the database.
Connection con;
Class.forName("org.gjt.mm.mysql.Driver";
con = DriverManager.getConnection("jdbc:mysql:///db?user=root&password=");
Try it out!
Queries regarding this is welcome. Either in this forum itself or u can contact in the mail, the id is

PHP MySQL data display problem

I am having trouble getting data to display on my web page.In Dreamweaver CS3, I created a new page.
Selected PHP as the type.
Saved it.
Connected a database and created a recordset (all using Dreamweavers menus. I did not write any code).
NOTE: The database is on a remote server.
The TEST button displayed the records from the recordset with no problem.
On the new page, I then typed some text.
Then dragged some fields from the Bindings tab to the page.
I saved it and then went to preview it in my browser.
The page comes up completely blank. Not even the text shows.
I then saved the page as an HTML page.
When I preview this in my browser, the text shows, but the fields and data do not.
I then tried creating a dynamic table (again, using the Dreamweaver menus.).
A similar thing happens, ie. If I save it as an HTML, the text shows and the column labels and border shows, but no data.
Nothing shows if I save it as a PHP file.
I can view the data online using files created by PHPMagic, so I know the data is there and retrievable.
It is just in pages created in Dreamweaver that don’t work.
What am I doing wrong?

My web server supports PHP. I can disply PHP pages created by other software packages, just not the Dreamweaver ones.

Subject: PHP MySQL data display problem
To view php pages - or pages with PHP code in them - in a browser, the page must be served up by a Web server that supports PHP. You can set up a testing server on your local machine for this purpose. Look for WAMP (Windows), MAMP (Mac), or XXAMP for some easily installed packages.

Dreamweaver 8 SQL Connection errors

Hi.. I am trying to use Dreamweaver 8 to connect to my SQL
Database hosted by Servage.net
When Dreamweaver tries to connect to the database, it puts
files into a folder called _mmServerScripts and uses them to
connect.
When I try to connect to test the database connection,
Dreamweaver gives me a 404 error saying thqat it cannot find the
file htp://www.domainname.com/_mmServerScripts/MMHTTPDB.php that it
has put even though I can see it and a couple of others in the
Online Filemanager and wneh I put the URL into my browser
I have also tried to give the files full (777) rights and
changed the owner to 'Webserver' to see if it was a rights problem
without any luck.
Even though this error pops up during testing, dreamweaver
still shows the database connection in the database window and when
I attempt to connect, it shows no errors but dies not find any
tables within the database and I know that they are there... I can
see them in phpMyAdmin.

Update:
I contacted Servage Support regarding this problem and the
responded with:
"Due to security considerations we do not allow connections
to our mysql server from outside our network. If we did allow this
the security of our systems would be affected."
but as far as I can see it, the SQL database is accessed via
the php pages uploaded to the website.. so as far as I can see, the
database is then connected to loacally (at the server) is this
correct??
is there another way to connect to the database or should I
create the database locally and upload it? or would this cause
linking problems later?

Please help setting up Mysql ASP connection on a Mac DW8

Dear All
I have posted previously but I still have not solved this
problem, and really need anybody with a mac DW setup to give some
advice. I have spoken to Adobe and trawled the net looking for a
solution to getting ASP and DW working on a mac. I know I need a
windows machine and a local network which I have. I have a real
issue making a database connection from within dreamweaver.
Please help anybody with experience.
Many thanks in advance
Graham

I don't know how you can define the MySQL database connection
string in DW,
because I only use DW for layout purposes (HTML + CSS). But I
have an
ASP/VBscript site running against a MySQL database, and it
successfully uses
the following connection string:
"DRIVER={MySQL ODBC 3.51 Driver};SERVER=" & myDBhost
& ";DATABASE=" &
myDBname & ";USER=" & myDBuserid & ";PASSWORD="
& myDBpassword &
";OPTION=3;"
Hope this helps.

An unknown error occurred when Dreamweaver tried to connect to this Contrib

Hello all,
I just started having a Dreamweaver problem that's perplexing me...
I have 2 machines, a G4 and a G5 both running Dreamweaver ( I have MX2004 and 8 on both machines, this problem effects both versions on the G5 only).
Everything was humming along just fine until the other day when suddenly I was receiving error messages on my G5 stating
"An unknown error occurred when Dreamweaver tried to connect to this Contribute site".
Then my local folder containing the website that I was working on would go gray (in Dreamweaver) and lose it's folder icon. It would still look like it was there, just no icon. When I would click on the drop down triangle it would state, " The local root folder, (and the folders name), does not exist. Please select a new local folder by clicking the Manage Sites button".
I then ran a couple of tests on the G4 and it connected fine, I was able to edit, upload/download, everything as usual. I then attempted to connect to the site with Transmit on the G5...no problem.
In the site definition I remembered that it may be set up to work with Contribute sites, but this was not the case, the box was unchecked.
I then had the idea to export the site key from the G4 and grab it onto the G5 and import it into Dreamweaver...I did this AND IT WORKED! Once...after that back to the 2 usual errors.
I found a work around for now...do my editing/site building in Dreamweaver, and upload with Transmit...this works fine...I've found that the errors only happen AFTER I've connected with the site(s). I've tried this with the other sites I maintain and it was the exact same thing.
Are there any similar experiences out there? This has really got me stumped... can't imagine what it is.
Any help would be greatly appreciated.
thanks

Java DB connectivity problems

I need troubleshooting techniques how to deal with database connectivity problems.
I am using netbean6m10, Java6.0_1b6 and my program reads these properties before opening the database.
lsfbvol.db.url="jdbc:derby:/etsdDB/ds8300DB;create=yes"
lsfbvol.db.driver=org.apache.derby.jdbc.EmbeddedDriver
For debugging purposes, I printed the driver to ensure it was read properly and it was.
DB Driver=org.apache.derby.jdbc.EmbeddedDriver
Below is the captured exception. Please advice.
Thanks

Thanks for the response.
This is a working program under MySQL and modified for a good practice to learn the new Java DB included in jdk6. Actually, all I changed was my property file which contained all the properties for URL and Driver for the DB.
My URL was pointing to my working-directory which happend to be my flash-card. I changed it to my C drive but still is having same problem.
About my driver not being loaded. My understanding was under jdk6 there was no need to load the driver for embeded Java DB because was already included into the system.
Not sure what to try next. Please advice.
Thanks. Arsi

MySQL gateway connection

Looks like plenty of folks here have similar problems getting the dg4odbc gateway working for MySQL. Hope someone that's tackled this can help me out.
Our configuration is such that we have our gateway machine separate from our Oracle database, and the MySQL machine is yet another server. We have installed and configured the gateway along with the unixODBC gateway and the MySQL connector. Running ./isql from the gateway successfully connects to the MySQL database and returns rows from specified tables.
Our difficulty is with setting up the listener.ora (on the gateway) and tnsnames.ora (on the Oracle host). Here are the contents of those files:
listenter.ora:
SID_LIST_LISTENER =
    (SID_DESC =
      (PROGRAM = dg4odbc)
      (ORACLE_HOME=/db01/app/oracle/product/gateways)

      (ADDRESS = (PROTOCOL = TCP)(HOST = gw_host)(PORT = 1521))
    (CONNECT_DATA = (SID= myodbc3))
    (HS=OK)
)Listener status on the gateway is:

I logged into sqlplus and create a public database link:

P.S. tnsping from the Oracle database to the gateway gives this:

Maybe it is sufficient to get the part where the libodbc.so library is loaded, so check where you'll find it in the strace file and provide this info until the error is visible in the traceHopefully this is what you wanted from truss.
