I use GlassFish 5 with mysql-connector-java-8.0.13.jar
and CLASSPATH values:
C:\Program Files\glassfish5\glassfish\lib
C:\Program Files\glassfish5\glassfish\domains\domain1\lib
C:\Program Files\glassfish5\glassfish\domains\domain1\lib\ext
After several restarts of both the server and the laptop it still gives this error:
Ping Connection Pool failed for MySQL_sakila. Class name is wrong or classpath is not set for : com.mysql.jdbc.jdbc2.optional.MysqlDataSource Please check the server.log for more details.
Properties
The issue is similar to this StackOverflow source but I have applied the answers there and none of them have helped.
What worked for me:
Datasource Classname: com.mysql.cj.jdbc.MysqlConnectionPoolDataSource
Two new "Additional Properties" to the JDBC Connection Pool :
useSSL = false
serverTimezone = UTC (this is not even true in my case, I am UTC+2)
Here one remark : when I installed MySQL instance, I expressly set it NOT to use SSL for the passwords from the option in the installer on the regarding page.
other "Additonal Properties " are :
password = myPass
databaseName = sakila
serverName = localhost
user = root
networkProtocol = jdbc
portNumber = 3306
.. and it succeeded
It worked for me too. Exellente! Although I used the
com.jdbc.jdbc2.optional.MysqlDataSource on Netbeans as my Datasource name but I think setting useSSL= false is real thing.
But I used com.mysql.cj.jdbc.MysqlConnectionPoolDataSource on glassfish server

I am trying to setup Xdebug with PhpStorm. When I try and validate my script, I get the following error:
Specified URL is not reachable, caused by: 'Request failed with status code 400'
The error used to display a 404 status code, but I applied the fix on this page: https://www.jetbrains.com/help/phpstorm/validating-the-configuration-of-the-debugging-engine.html#troubleshooting-validation-results
I haven't seen anything online for fixing a 400 status code.
I have the site setup on a local environment using nginx and an upstream using php-fpm.sock.
upstream site_backend {
server unix:/var/run/php/php7.4-fpm.sock;
}
And here is my xdebug.ini:
GNU nano 4.8 /etc/php/7.4/fpm/conf.d/20-xdebug.ini
zend_extension=xdebug.so
xdebug.remote_enable=1
xdebug.remote_handler=dbgp
xdebug.remote_mode=req
xdebug.remote_host=localhost
xdebug.remote_port=9000
xdebug.var_display_max_depth = -1
xdebug.var_display_max_children = -1
xdebug.var_display_max_data = -1
xdebug.idekey = "PHPSTORM"
The site works, only Xdebug isn't working. PhpStorm is not registering anything from Xdebug.
Not sure what else is needed, let me know if you need anything else.
UPDATE:
Xdebug is version 3.0.4.
In the nginx error log, I saw something that might be helpful:
2021/04/19 10:26:08 [error] 736434#736434: *72 access forbidden by rule, client: 127.0.0.1, server: mysite.localhost, request: "GET /_intellij_phpdebug_validator.php HTTP/1.1", host: "mysite.localhost"
UPDATE 2:
I made the changes at https://xdebug.org/docs/upgrade_guide, still isn't working. Here is the update xdebug.ini:
zend_extension=xdebug.so
xdebug.mode=debug
xdebug.session=PHPSTORM
xdebug.start_with_request=yes
Not sure if it's correct configuration. I also double checked to make sure PHPStorm is listening on port 9003, which it is. I also restarted php-fpm as well.
I got the same issue and I was able to resolve this buy just replacing the default URL assigned (http://127.0.0.1) with my virtual host URL in PHPStorm > Run > Web Server Debug Validation > URL to validation script.
OS: Ubuntu 20.04.3 LTS
PHP version: 7.4.3
XDebug version: 2.9.2
/etc/php/7.4/mods-available/xdebug.ini:
zend_extension=xdebug.so
xdebug.remote_autostart = 1
xdebug.remote_enable = 1
xdebug.remote_handler = dbgp
xdebug.remote_host = 127.0.0.1
xdebug.remote_log = /tmp/xdebug_remote.log
xdebug.remote_mode = req
xdebug.remote_port = 9000 #if you want to change the port you can change
xdebug.mode=debug
xdebug.start_with_request = yes
I got the same problem and I resolved this buy just
changing the value in the php.ini file of the xdebug.start_upon_error from the default "default" to "yes" due too https://www.jetbrains.com/help/phpstorm/configuring-xdebug.html#configuring-xdebug-docker
I got the same issue by using ddev ( = a docker wrapper).
The absolute path to my project is /var/www/html in ddev.
I had to write /var/www/html as the absolute path to my project in the phpstorm settings at php>servers.
I'm using grails 2.5.0 and mysql 8.0.13
dbCreate = "create-drop"
url = "jdbc:mysql://localhost/bet?serverTimezone=UTC"
driverClassName = "com.mysql.cj.jdbc.Driver"
username = "root"
password = "pepito"
For example, if I save a "Product", it's work, but if I change some code in any controller I got this error:
The type registry TypeRegistry(id=334490881,loader=groovy.lang.GroovyClassLoader) does not know about type id 1839.
Stacktrace follows:
Message: The type registry TypeRegistry(id=334490881,loader=groovy.lang.GroovyClassLoader) does not know about type id 1839
Spring Loaded: Cannot reload new version of com.bet.controller.AgentController
Reason: Interfaces changed from [org/codehaus/groovy/grails/orm/support/TransactionManagerAware, groovy/lang/GroovyObject] to [groovy/lang/GroovyObject]
Y tested in sql server and it's work
In that situation, I normally restart the application. When we change a lot in a controller, the application could not load the latest updated version of the compiled class according to that controller in some cases.
I want to build a simple app that connects to remote MySQL server. However, I can't make it work.
import ballerina/io;
import ballerina/jdbc;
import ballerina/mysql;
endpoint jdbc:Client jiraDB {
host: "jdbc:mysql://DB-SERVER:3306/jira",
username: "jira",
password: "PWD",
poolOptions: { maximumPoolSize: 5 }
};
type Domain record {
string domain,
string jira,
};
function main(string... args) {
var ret = jiraDB->select("SELECT * FROM `domains`", ());
table domainTable;
match ret {
table tableReturned => domainTable = tableReturned;
error e => io:println("Select data from domains table failed: " + e.message);
}
while(domainTable.hasNext()) {
var domain = <Domain>domainTable.getNext();
match domain {
Domain d => io:println("Domain: " + d.domain);
error e => io:println("Error in get employee from table: "
+ e.message);
}
}
}
The structure of MySQL is not really important. I think it has to do with missing / wrongly used JDBC/MySQL library.
Do you please have any ideas how to make it work on Mac OS X ?
$ ballerina run hello.bal
error: ballerina/runtime:CallFailedException, message: call failed
at ..<stop>(hello.bal:5)
caused by error
at ballerina/jdbc:stop(endpoint.bal:66)
I'm using latest Mac OS X with:
$ ballerina --version
Ballerina 0.980.1
First, the latest ballerina version is 0.981.0. It would be great if you could use the latest version since it would include latest bug fixes and improvements.
In Ballerina, there is a generic jdbc client which can be used to connect to any database which has a jdbc driver. In addition, for mysql and h2 there are two clients implemented specifically for those two databases.
When connecting to mysql, you could either use the generic jdbc client or the mysql specific client. The recommendation is to use the mysql specific client.
In your code snippet, I can see you are using jdbc client. As Anoukh mentioned above, the endpoint configuration is incorrect.
Following is a sample configuration for generic jdbc client endpoint.
endpoint jdbc:Client testDB {
url: "jdbc:mysql://localhost:3306/testdb",
username: "user1",
password: "pass1",
poolOptions: { maximumPoolSize: 5 }
};
And following is a sample configuration of mysql client endpoint.
endpoint mysql:Client testDB {
host: "localhost",
port: 3306,
name: "testDB",
username: "user1",
password: "pass1",
poolOptions: { maximumPoolSize: 5 }
};
In order to use either of the clients, you need to copy the mysql jdbc driver to ${BALLERINA_HOME}/bre/lib.
Even after correcting your configuration and copying the driver, if you still face the issue, please check whether file named ballerina-internal.log is created where you are running your bal file and share. Also please share the mysql database and driver version you are using.
Have you copied the MySQL JDBC driver to the BALLERINA_HOME/bre/lib folder?
You can find the ballerina home using which ballerina command.
You can download the mysql jdbc driver from http://central.maven.org/maven2/mysql/mysql-connector-java/5.1.6/mysql-connector-java-5.1.6.jar
The issue might be in the jiraDB endpoint configurations. As per the API docs, the config for the URL of the database is to be given as url instead of host.
I was not able to connect to Mysql and I faced a driver instance error. I solved it! I'm not sure to post my answer at the good place but I think it will be a good resource to fix some problems with Mysql connections issues in Ballerina.
In my terminal : echo $BALLERINA_HOME
/Library/Ballerina/ballerina-0.990.2
Copy the good jar in the right place !
Go to : http://central.maven.org/maven2/mysql/mysql-connector-java/
I have downloaded the latest stable version (at the time of writing 8.0.15).
Copy the jar in $BALLERINA_HOME/bre/lib/
I had an error with a prior version.
Be careful that your jar have the right extension (the .jar not the repository with the same name).
Also be sure to have fulfilled the recommandations (see the doc of Oracle when installing a jar, i.e setting the classpath)
In your terminal, set the class path :
export CLASSPATH=$CLASSPATH:/Library/Ballerina/ballerina-0.990.2/bre/lib/mysql-connector-java-8.0.15
Then it will work !
I have a spring boot application that currently has a "mysql" profile that sets the following properties:
spring.datasource.url =
spring.datasource.username =
spring.datasource.password =
in /resources/application-mysql.properties file.
This is working great. When I run the mysql profile it connects to the local mysql database. When I don't run the mysql profile it uses the default h2 database. Next I want to get rid of the application.my-sql.properties and pass those values in via the command line. From the documentation here I would expect something like the following to work. But strangely, it never gets these properties and runs the h2 database instead.
java -jar myapp-0.0.1-SNAPSHOT.jar --spring.application.json='{"spring": {"datasource": {"url":"jdbc:mysql://localhost:3306/db", "username":"user","password":"pw"}}}'
I can confirm that this does work. As Vaelyr pointed out in the comments, setting it as system argument worked:
-Dspring.application.json='{"spring":{"datasource":{"username":"yourusername","password":"yourpassword"}}}'
I have a strange problem that recently popped on my Debian Squeeze server.
I've had Exim4 configured to use SMTP-AUTH with encryption setup and running on this box for a long time, but now it doesn't work.
At first I thought it was maybe my certificates expired, but that wasn't the case, they're good for several more years.
It appears that the server isn't listening on port 25 any longer.
If I try to telnet to port 25 it times out.
If I run netstat -tulpen on the server nothing is listening on port 25.
I'm using the splitconf for Exim4.
In conf.d/main I'm enabling MAIN_TLS_ENABLE=true
In conf.d/auth/30_exim4-config_examples I have the following
# Authenticate against local passwords using sasl2-bin
# Requires exim_uid to be a member of sasl group, see README.Debian.gz
plain_saslauthd_server:
driver = plaintext
public_name = PLAIN
server_condition = ${if saslauthd{{$auth2}{$auth3}}{1}{0}}
server_set_id = $auth2
server_prompts = :
.ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}
.endif
#
login_saslauthd_server:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
# don't send system passwords over unencrypted connections
server_condition = ${if saslauthd{{$auth1}{$auth2}}{1}{0}}
server_set_id = $auth1
.ifndef AUTH_SERVER_ALLOW_NOTLS_PASSWORDS
server_advertise_condition = ${if eq{$tls_cipher}{}{}{*}}
.endif
On the server if I run this command:
swaks -a -tls -q HELO -s localhost -au A_USER_NAME -ap '<>'
I get this ...
=== Trying localhost:25...
* Error connecting 0.0.0.0 to localhost:25:
* IO::Socket::INET: connect: Connection refused
Can someone point me to some more advanced debugging techniques?
OK. I figured it out.
Comcast blocks port 25. I don't know why this is coming up now, unless they've recently started blocking it.
I had to change a line in /etc/default/exim4
From this
SMTPLISTENEROPTIONS='-oX 25 -oP /var/run/exim4/exim.pid'
To this
SMTPLISTENEROPTIONS='-oX 465:25 -oP /var/run/exim4/exim.pid'
I also added this to /etc/exim4/conf.d/main/03_exim4-config_tlsoptions
tls_on_connect_ports=465
It's odd that this just popped up, unless a Debian package updated the /etc/default/exim4 file. It's confusing, but it's working. Hopefully this will be helpful to someone in the future.
Cheers.
