I have cloned 'knowage' BI tool to my local cetnos 7 server and successfully ran the docker containers. My challenge is in connecting to a mariadb database that is in the Host machine! I want the knowage container to access that database in the Host machine. below is my server.xml file for the connection configs used by knowage..
<GlobalNamingResources>
<Resource name="jdbc/datasource" auth="Container"
type="javax.sql.DataSource"
driverClassName="org.mariadb.jdbc.Driver"
url="jdbc:mariadb://ip-addr:3306/datasource"
username="beberu"
password="***********"
maxActive="20" maxIdle="10"
maxWait="-1"/>
<!-- KNOWAGE -->
<Resource auth="Container" driverClassName="org.mariadb.jdbc.Driver" maxActive="20" maxIdle="10" maxWait="-1" name="jdbc/knowage" type="javax.sql.DataSource" url="jdbc:mysql://1$
<Resource auth="Container" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" name="UserDatabase" pathname="$
<ResourceLink global="jdbc/datasource" name="jdbc/datasource" type="javax.sql.DataSource"/>

You have to use the ip address of the docker0 interface in the place of 10.66.110.7.
You can get the ip address using this command.
$ ip addr show docker0
In the result use the ip after, inet.

We have an application provided by a 3rd party vendor that runs on Tomcat 8 and JDK 8 to an Oracle 12 DB with ojdbc7.jar & xdb6.jar driver. The application works, but is slower than expected. When investigating it appears the application is configured to use connection pooling, but it appears the application is creating new connections per query, and not using any of the initially created connections to the Database.
Unfortunately, I don't have access to the code of the 3rd party app. But, hoping for an idea on what I am missing in the Tomcat setting to have pooling work.
I've tried going through Apache's documentation for the older Oracle connections, and trying other options found on the web.
<Resource name="jdbc/DataSource" auth="Container"
type="javax.sql.DataSource"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:#localhost:1521:XE"

initialSize="5" maxTotal="100" maxIdle="-1"
maxWaitMillis="30000"
validationQuery="select 1 from dual"
testOnBorrow="true"
accessToUnderlyingConnectionAllowed = "true"
connectionProperties="defaultRowPrefetch=100"
removeAbandoned = "true"
removeAbandonedTimeout = "30"/>
You can check tomcat docs, mainly use factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
example on how to configure a resource for JNDI lookups
<Resource name="jdbc/TestDB"

you can specify pooling by defining type and factory
type="javax.sql.DataSource"
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
We are using tomcat jdbc pool in our project. The connection pool configuration is
<Resource name="jdbc/cc" auth="Container" type="javax.sql.DataSource" username="xx" password="plain text"
driverClassName="com.mysql.jdbc.Driver" url="jdbc:mysql://localhost:3306/xx?autoReconnect=true&useUnicode=true&characterEncoding=utf8"
maxActive="50" maxIdle="25" minIdle="10" maxWait="10000" testOnBorrow="true"
validationQuery="SELECT 1" factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"/>
We want to use encrypted DB password in configuration rather than plain text. How we can do this, please help me on this. ( we know how to do this if we are using tomcat dbcp, but the same implementation is not working for tomcat jdbc)
I have an application that uses the built-in Tomcat connection pool, and for the most part it works. A problem arises when I'm trying to use another pool to get a different set of connection from the same database, but from a different username/password (It's an oracle database that uses 2 usernames to access different namespaces of tables and function).
The first pool is accepted, but for the second one, I'm getting this error
15:09:47.157 [http-nio-8081-exec-5] ERROR com.applicationname.providers.ConnectionManager - NamingException in MyDataSource

Here is my configuration:

I think you're looking up the second datasource via name "appdb_two", but should be using "jdbc/appdb_two" - it's hard to see from the stacktrace alone, code for lookup would be helpful.
Also check that your web.xml has references to both data sources (<resource-ref> elements).
I am unable to get database connection in Tomcat7. i am using oracle linux as a OS. Below are my DB connection pool configuration.
server.xml
<GlobalNamingResources>
<!-- Editable user database that can also be used by

context.xml
<ResourceLink global="jdbc/weblogin01" name="jdbc/weblogin01" type="javax.sql.DataSource"/>
<ResourceLink global="jdbc/osswebportal" name="jdbc/osswebportal" type="javax.sql.DataSource"/>
i have also define all the db details in tomcat's catalina.properties
resource.osswebportal.url=jdbc:oracle:thin:#test.com:1522:GPSP
resource.osswebportal.username=User
resource.osswebportal.password=password
resource.weblogin01.url=jdbc:oracle:thin:#test2:1522:GSPS
resource.weblogin01.username=User1
resource.weblogin01.password=Password
And also i have placed the jdbc jar in both tomcat's lib directory as well Applications's WEB_INF/lib directory.
put the Driver Jar file in the server lib folder, I think this will solve your issue.
I have a Java RESTful Webservice running on Tomcat7 in Ubuntu.
When I change fields in the Database the Webservice returns the old values.
When i restart the service, it returns the new values.
this is my Context.xml:
<Context>
<Resource name="jdbc/schischule"
auth="Container"
type="javax.sql.DataSource"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://IP:3306/Skischul_DB"
username="admin"
password="pwd"
maxActive="20"
maxIdle="30"
maxWait="-1"
/>
</Context>
Has anyone an idea why Tomcat doesn't refresh the data?
