Crowd Plugin deployment

[Umesh Kanaujia]

Created the crowd plugin, connecting to Oracla DB using JNDI.

Deployed the plug in code on \atlassian-crowd-3.0.1\atlassian-crowd-3.0.1\shared\plugins & setup the JNDI in \atlassian-crowd-3.0.1\apache-tomcat using this link : https://tomcat.apache.org/tomcat-7.0-doc/jndi-datasource-examples-howto.html

Error

Cannot create JDBC driver of class '' for connect URL 'null'

Can you please advice the approach to deploy plug-in & data source location to configure ?  

Thanks,

Umesh Kanaujia

Thanks Lukasz.

To fix the issue, we performed the following steps:-

Java Code

Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/TestDS");
conn = ds.getConnection();

Configuration

Need to made following changes at this location (${atlassian-crowd-3.0.1}\apache-tomcat\conf) :-

web.xml

<resource-ref>
<description>Oracle Datasource example</description>
<res-ref-name>jdbc/TestDS</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>

context.xml

<Resource name="jdbc/TestDS"
auth="Container"
type="javax.sql.DataSource"
username="testuser"
password="testuser"
driverClassName="oracle.jdbc.OracleDriver"
url="jdbc:oracle:thin:@xxx.amazonaws.com:1521:TestDB"
maxActive="10"
maxIdle="2"
removeAbandoned="true"
removeAbandonedTimeout="30"
maxWait="5000"
logAbandoned="true"
accessToUnderlyingConnectionAllowed="true"/>

Hi Umesh,

Looks like you might be missing the driverClassName attribute on your JNDI resource definition in your context.xml? Please double-check that all the required attributes are set there. The Tomcat documentation has an example in the "Context configuration" section:

  <Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/javatest"/>
