Where database configuration files are stored? - jasperserver

I"m trying to find database connection configuration files inside JasperReports Server. If you can tell me where JR Server stores database configuration files then it will be great help

Internal DB configuration
You can find JasperReports Server (JRS) internal DB configuration at <tomcat>\webapps\jasperserver\META-INF\context.xml file.
The sample of this configuration file (of my local JRS deployed on Tomcat):
<Context path="/jasperserver" reloadable="false">
<Resource name="jdbc/jasperserver" auth="Container" type="javax.sql.DataSource" maxActive="100" maxIdle="30" maxWait="10000"
username="jasperdb" password="password" driverClassName="org.postgresql.Driver" accessToUnderlyingConnectionAllowed="true"
validationQuery="SELECT 1" testOnBorrow="true"
url="jdbc:postgresql://127.0.0.1:5432/jasperserver?useUnicode=true&amp;characterEncoding=UTF-8&amp;autoReconnect=true&amp;autoReconnectForPools=true"
factory="com.jaspersoft.jasperserver.tomcat.jndi.JSCommonsBasicDataSourceFactory"/>
<Manager pathname=""/>
</Context>
As you can see the username and password stored as just an unencrypted text: username="jasperdb" password="password".
And the db connection string is storing like this: url="jdbc:postgresql://127.0.0.1:5432/jasperserver
I used this credentials for DB connect with pgAdmin (my local JRS is using Postgres):
Where datasources are stored
The table jijdbcdatasource contains information about jdbc based datasources.
For example, I created the new datasource like this:
The all parameters were placed at new row of jijdbcdatasource table:

DB2 driver settings in Websphere Liberty

I have application running in Websphere Liberty and uses DB2 in Z/oS. I have set the db2 driver proerties in DB2JCCConfiguration.properties .How can make sure that the server has picked up properties I have set .I am not sure how to verify the trace to see if the properties are applied to server
To configure a datasource (for any backend DB) with Liberty, you can add configuration like this to your server.xml:
<featureManager>
<feature>jdbc-4.2</feature>
</featureManager>
<library id="driver-library">
<fileset dir="/path/to/driver/dir" includes="*.jar"/>
</library>
<dataSource id="DefaultDataSource" jndiName="jdbc/myDB">
<jdbcDriver libraryRef="driver-library"/>
<properties.db2.jcc serverName="example.db.hostname.com" portNumber="50000"
databaseName="myDB"
user="exampleUser"
password="examplePassword"
currentSchema="xyz"
fullyMaterializeInputStreams="true"/>
</dataSource>
To test if your configuration is correct and that your Liberty server can connect to your DB2 database, add the following configuration:
<featureManager>
<feature>appSecurity-3.0</feature>
<feature>restConnector-2.0</feature>
<feature>jdbc-4.2</feature>
</featureManager>
<!-- Any security mechanism can be used, <quickStartSecurity> is the simplest -->
<quickStartSecurity userName="admin" userPassword="admin"/>
And then go to: https://localhost:9443/ibm/api/validation/dataSource/DefaultDataSource
(this assumes your <dataSource> id is DefaultDataSource)

How to enable failover for a postgresql jdbc data source

I have a data source defined in a Liberty application server for postgresql
<dataSource jdbcDriverRef="PostgreSQLDriver" ...>
<properties password="..." user="admin" serverName="server" portNumber="2020" databaseName="dbname" ssl="false"
</dataSource>
I see that I can enable failover on a jdbc connection by specifying a url like:
jdbc:postgresql://host1:port,host2:port,host3:port/dbname
Is there any way that this failover url can be provided to a application server datasource?
Yes, you can specify any key/value pair on the <properties> element and Liberty will supply it to the vendor data source class. In this case, the property would be URL="jdbc:postgresql://host1:port,host2:port,host3:port/dbname"
Also, note that in more recent versions of Liberty, there is a properties.postgresql which is specific to Postgres and better documents the available settings for it.
Here is an example,
<dataSource jdbcDriverRef="PostgreSQLDriver" ...>
<properties.postgresql password="..." user="admin" URL="jdbc:postgresql://host1:port,host2:port,host3:port/dbname" ssl="false"
</dataSource>

How to configure Read Only Datasource in Jboss teiid

I have configured a Redshift Datasource in Jboss teiid. I want to know how to make my Datasource Read Only. I know how make Read Only resources on VDB level using Dataroles (Ref:- https://github.com/teiid/teiid-quickstarts/blob/master/vdb-dataroles/src/vdb/portfolio-vdb.xml). But this would allow to create new VDBs which are not Read Only which is a vulnerability in my case. I want to do this in Datasource configuration level in domain.xml. Is there any guidance on how to do this.
I am not using teiid Designer and I configure Datasources editing the domain.xml file. I add the fallowing Datasource under the Datasources sub element in the domain.xml file
<datasource jndi-name="java:jboss/datasources/redshiftDS" pool-name="redshiftDS" enabled="true" use-java-context="true">
<connection-url>jdbc:redshift://***********.com:5439/schema</connection-url>
<driver>redshift</driver>
<security>
<user-name>${user_name}</user-name>
<password>${pw}</password>
</security>
<pool>
<!--min-pool-size>
10
</min-pool-size-->
<max-pool-size>
5
</max-pool-size>
</pool>
</datasource>
Is there any way I can configure the Datasource to be read only here. For an example adding something like
<access-permission>
read-only
</access-permission>
The simplest alternative from a Teiid perspective is to add a data role for any authenticated for all schemas that you don't users to have write access to:
<data-role name="read-only" any-authenticated="true" allow-create-temporary-tables="true">
<description>read only access</description>
<permission>
<resource-name>schema name</resource-name>
<allow-read>true</allow-read>
<allow-execute>true</allow-execute>
</permission>
</data-role>
There was a flag on translators to set them as immutable - but support for that was removed.
Mark all your tables as non updatable. If you are using designer there is property on table or columns or you can do same using DDL too.

Single Connection String with Multiple Entity Framework Models(Data First)

I have 3 different project having their respective EF entity data model pointing to same database.I don't want to save connection string in each of these project's app.config file but want to share it between my models.
I see this link on stackoverflow How to share a connection string between multiple entity data model.
But the problem with it is if I will update the EF model it will overwrite the code in EF Model's context and it will inherit from DbContext not from BaseContext.
Please help how can I resolve this.
You have to move your connection string in a separate config file:
ConnectionStrings.config
<?xml version="1.0" encoding="utf-8" ?>
<connectionStrings>
<add name="connectionString"
connectionString="Integrated Security=SSPI; Persist Security Info=False; Initial Catalog=DbName; Data Source=.\SQLExpress;"
providerName="System.Data.SqlClient" />
</connectionStrings>
Modify the connection string so that fit your requirement.
Then you can share it with all your projects like that:
1) Open your App.config (This file found in your project)
2) Add this line code somewhere behind </configSections>
...
<connectionStrings configSource="ConnectionStrings.config"/>
...
The trick in configSource:
"Gets or sets the name of the include file in which the associated configuration section is defined, if such a file exists."
https://msdn.microsoft.com/en-us/library/system.configuration.sectioninformation.configsource(v=vs.110).aspx
What will happened:
ConnectionStrings.config must be first copied
All YourApplicationName.config will reference the shared connection string config file.
If the project does not have any App.config then just add it! or you can also loaded manually with ConfigurationSettings.
This is the best way to share the database configuration between the app.configs and when you change for example the Sql Server name, then you have only to modify the ConnectionStrings.config and not all App.configs!
It resolved as connection string always picked from MVC project and all other class library projects are referencing it automatically.

Correct way to make datasources/resources a deploy-time setting

I have a web-app that requires two settings:
A JDBC datasource
A string token
I desperately want to be able to deploy one .war to various different containers (jetty,tomcat,gf3 minimum) and configure these settings at application level within the container.
My code does this:
InitialContext ctx = new InitialContext();
Context envCtx = (javax.naming.Context) ctx.lookup("java:comp/env");
token = (String)envCtx.lookup("token");
ds = (DataSource)envCtx.lookup("jdbc/datasource")
Let's assume I've used the glassfish management interface to create two jdbc resources: jdbc/test-datasource and jdbc/live-datasource which connect to different copies of the same schema, on different servers, different credentials etc. Say I want to deploy this to glassfish with and point it at the test datasource, I might have this in my sun-web.xml:
...
<resource-ref>
<res-ref-name>jdbc/datasource</res-ref-name>
<jndi-name>jdbc/test-datasource</jndi-name>
</resource-ref>
...
but
sun-web.xml goes inside my war, right?
surely there must be a way to do this through the management interface
Am I even trying to do the right thing? Do other containers make this any easier? I'd be particularly interested in how jetty 7 handles this since I use it for development.
EDIT Tomcat has a reasonable way to do this:
Create $TOMCAT_HOME/conf/Catalina/localhost/webapp.xml with:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiResourceLocking="false" privileged="true">
<!-- String resource -->
<Environment name="token" value="value of token" type="java.lang.String" override="false" />
<!-- Linking to a global resource -->
<ResourceLink name="jdbc/datasource1" global="jdbc/test" type="javax.sql.DataSource" />
<!-- Derby -->
<Resource name="jdbc/datasource2"
type="javax.sql.DataSource"
auth="Container"
driverClassName="org.apache.derby.jdbc.EmbeddedDataSource"
url="jdbc:derby:test;create=true"
/>
<!-- H2 -->
<Resource name="jdbc/datasource3"
type="javax.sql.DataSource"
auth="Container"
driverClassName="org.h2.jdbcx.JdbcDataSource"
url="jdbc:h2:~/test"
username="sa"
password=""
/>
</Context>
Note that override="false" means the opposite. It means that this setting can't be overriden by web.xml.
I like this approach because the file is part of the container configuration not the war, but it's not part of the global configuration; it's webapp specific.
I guess I expect a bit more from glassfish since it is supposed to have a full web admin interface, but I would be happy enough with something equivalent to the above.
For GF v3, you may want to try leveraging the --deploymentplan option of the deploy subcommand of asadmin. It is discussed on the man page for the deploy subcommand.
We had just this issue when migrating from Tomcat to Glassfish 3. Here is what works for us.
In the Glassfish admin console, configure datasources (JDBC connection pools and resources) for DEV/TEST/PROD/etc.
Record your deployment time parameters (in our case database connect info) in properties file. For example:
# Database connection properties
dev=jdbc/dbdev
test=jdbc/dbtest
prod=jdbc/dbprod
Each web app can load the same database properties file.
Lookup the JDBC resource as follows.
import java.sql.Connection;
import javax.sql.DataSource;
import java.sql.SQLException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
/**
* #param resourceName the resource name of the connection pool (eg jdbc/dbdev)
* #return Connection a pooled connection from the data source
* associated with resourceName
* #throws NamingException will be thrown if resource name is not found
*/
public Connection getDatabaseConnection(String resourceName)
throws NamingException, SQLException {
Context initContext = new InitialContext();
DataSource pooledDataSource = (DataSource) initContext.lookup(resourceName);
return pooledDataSource.getConnection();
}
Note that this is not the usual two step process involving a look up using the naming context "java:comp/env." I have no idea if this works in application containers other than GF3, but in GF3 there is no need to add resource descriptors to web.xml when using the above approach.
I'm not sure to really understand the question/problem.
As an Application Component Provider, you declare the resource(s) required by your application in a standard way (container agnostic) in the web.xml.
At deployment time, the Application Deployer and Administrator is supposed to follow the instructions provided by the Application Component Provider to resolve external dependencies (amongst other things) for example by creating a datasource at the application server level and mapping its real JNDI name to the resource name used by the application through the use of an application server specific deployment descriptor (e.g. the sun-web.xml for GlassFish). Obviously, this is a container specific step and thus not covered by the Java EE specification.
Now, if you want to change the database an application is using, you'll have to either:
change the mapping in the application server deployment descriptor - or -
modify the configuration of the existing datasource to make it points on another database.
Having an admin interface doesn't really change anything. If I missed something, don't hesitate to let me know. And just in case, maybe have a look at this previous answer.
