I can't connected to postgres server by my jsp. I have an error:
root cause
java.net.SocketException: Permesso negato (connect failed)
java.net.PlainSocketImpl.socketConnect(Native Method)
java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:350)
I connect to postgres server with phpPgAdmin and with my drupal sites?
Why I can't connect with my jsp??
I have this error in this line
connection = DriverManager.getConnection("jdbc:postgresql://localhost/tpinet.it", "postgres","xxxx");
I have jdbc driver in the correct path and I have installed 4 drupal sites that use this database and they are online.
Why in the jsp i have this error?

Trying to add a Postgres database on Metabase via SSH tunneling I ran into an error giving me the following error message: "Server error encountered"
My logs are very similar to #williamjacksn 's logs on the post:
http://discourse.metabase.com/t/ssh-tunnel-failure/2469
I am certain that my credentials are OK since I use the same for a Postico SSH connection as well as a DBeaver connection.
I already checked the following fix: https://github.com/metabase/metabase/pull/6970
Howerver I have no idea how to use it as i cannot find the ssh.clj file on my machine.
Would there be a fix for this ?
Extra info:
Install via the .jar file. Working on Firefox 58.0.2 | Mac OSX 10.10.5
Thanks in advance

I already checked the following fix: https://github.com/metabase/metabase/pull/6970 Howerver I have no idea how to use it as i cannot find the ssh.clj file on my machine.
To try out the ssh.clj changes proposed in the pull request you need to get the source code from GitHub, then build Metabase yourself from source code. I just happen to have described the steps over on the Metabase discussion forum for someone in a similar situation (though needing a different PR for a different purpose):

I was trying to follow some EJB tutorial, most of them started talking about JNDI, and I am having trouble to get the service running on the JBOSS AS.
I have tried both the community and EAP version of JBoss in Eclipse, but both fails.
So now whenever I run lines like BeanRemote beanRemote = (BeanRemote) context.lookup("somecontext"); it throws these error.
javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]

well of course it is caused by the port not opened, but I think its because the Jboss server is not providing the service, although its web port and admin port 8080 and 9990 is working fine.
I am using eclipse Oxygen 4.7.0, I have downloaded the Red Hat JBoss developer Studio. I added the server via the "New Server" wizard, then downloaded the server runtimes within the wizard. However there just seems no way to configure jndi, nor can I find any file that is related to jndi or jnp in the downloaded path. The XML configuration showed that only Management 9990 and Web 8080 port is open.
I don't understand why is this not enabled by default, and I don't know what to do. Is JNDI configurable somewhere in the management console? please help
Turns out method of linking to jndi changed in EAP 7 from EAP 5
this articles shows the correct method.
jndi.properties has been changed to jboss-ejb-client.properties, and the standard config now becomes
endpoint.name=client-endpoint
remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED=false
remote.connections=default
remote.connection.default.host=yourhostaddress
remote.connection.default.port = 8080
remote.connection.default.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS=false
and context lookup string has been changed to
ejb:<app-name>/<module-name>/<distinct-name>/<bean-name>!<fully-qualified-classname-of-the-remote-interface>
i'm trying to connect my spring boot app to a remote mongodb database.
When i run my app i got this error:

By default MongoDB only binds to the loopback interface which makes it only accessible from localhost. To change that you need to edit this line in mongod.conf file;
you can change it to allow LAN and local connections or you can remove or comment out that line bind_ip = 127.0.0.1 to allow all connections.

I am not able to shutdown jboss server with the below command.
Command :
JBOSS_HOME/bin/jboss-cli.sh --connect controller=$SERVER_IP_ADDRESS:$SERVER_PORT command=:shutdown
Each time I was killing the server to restart which is not a good process to do. as we are moving to PROD environment we should use shutdown command to stop the server instead of killing
I am getting the below error. Please help.

The JBoss CLI is attempting to connect to the native management endpoint for the running JBoss and send a shutdown command. It looks like it's trying to send to 10.0.15.162:8080 which is not the right port (most likely).
Take a look in your bin/jboss-cli.xml file which should contain the host and port to connect to. For example:
<default-controller>
<host>localhost</host>
<port>9999</port>
</default-controller>

I am able to connect to the DB through the application deployed in BlueMix.
How are you populating the connection credentials? The application will have access the VCAP_SERVICES when run on Bluemix, but unless you have specifically copied that environment variable to your Eclipse environment, that information will not be available to your application.
The error indicates that the connection was refused. This most likely means that the host and port combination you've entered is incorrect. You'll want to ensure that you can connect to the host.
You can check that your local system can connect by doing nc -vz xxxxx.dblayer.com 10000 where xxxxx.dblayer.com is the full hostname provided to you within the variable and 10000 is the port, also provided.
It seems as though your syntax/configuration may not be correct as a connection being refused would indicate that it cannot connect however it's not clear from your post what hostname/port it's actually trying to connect to.
