JNDI and Spring configuration - jee:lookup - spring

Question

I wanted to use JNDI to publish my class as one of the resources. In context.xml of Tomcat I have
<Resource
name="jdbc/dialect"
type="pl.meble.taboret.utils.SQLiteDialect"
auth="Container"/>
in my web.xml
<resource-ref>
<description>sqlite dialect</description>
<res-ref-name>jdbc/dialect</res-ref-name>
<res-type>pl.meble.taboret.utils.SQLiteDialect</res-type>
<res-auth>Container</res-auth>
</resource-ref>
and in one of the Spring configuration files:
INFO : org.springframework.beans.factory.support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory#18706f6: defining beans
djfdoigjdoijfdsofjsdoij//the message added at the end of no-parameter constructor of SQLite dialect class

I added printing to the end of no-parameter constructor, and it seems that the object is constructed, so I don't know why it complains about Invocation of init method failed

Answer 1

I am pretty sure you need to use a driver not a dialect (this is my setup for MySQL, just change driver for your specific sql impl).
<Resource name="jdbc/myname" auth="Container" type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="user" password="pass" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://url/db"/>
and then
<resource-ref>
<description>The JNDI Database resource</description>
<res-ref-name>jdbc/myname</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Application</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
I think you will want to set your hibernate.dialect to pl.meble.taboret.utils.SQLiteDialect instead of what you are doing.

Answer 2

Try the following:
<Resource
name="jdbc/dialect"
type="java.lang.String"
value="pl.meble.taboret.utils.SQLiteDialect"
auth="Container"/>
<resource-ref>
<description>sqlite dialect</description>
<res-ref-name>jdbc/dialect</res-ref-name>
<res-type>java.lang.String</res-type>
<res-auth>Container</res-auth>
</resource-ref>
then perform your JNDI lookup, cast the value as a String and feed it to Class.forName() method.
