Help: Context.xml Resource difference between 5.0.x and 5.5.x ?
I'm having trouble moving my webapp from Tomcat 5.0 to 5.5. The dataSource in Context.xml seems to be the issue.
According to the 'JNDI how-to' documentation for 5.0 and 5.5, it looks like the '<ResourceParams>' tag has been removed from the Context.xml and instead you can now supply arbitrary attributes to the <Resource> tag itself.
In 5.0, my Context.xml looked like this and it worked fine:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiResourceLocking="true" docBase="myapp" path="/myapp">
<Resource name="jdbc/db1" auth="Container"
type="oracle.jdbc.pool.OracleDataSource" />
<ResourceParams name="jdbc/db1">
<parameter>
<name>factory</name>
<value>oracle.jdbc.pool.OracleDataSourceFactory</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>oracle.jdbc.driver.OracleDriver</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:oracle:thin:@xx:xx:xx</value>
</parameter>
<parameter>
<name>user</name>
<value>xx</value>
</parameter>
<parameter>
<name>password</name>
<value>xx</value>
</parameter>
</ResourceParams>
</Context>
...note that oracle's factory requires "user", not "username".
Moving to 5.5, I changed it to:
<?xml version="1.0" encoding="UTF-8"?>
<Context antiResourceLocking="true" docBase="myapp" path="/myapp">
<Resource auth="Container"
driverClassName="oracle.jdbc.driver.OracleDriver"
factory="oracle.jdbc.pool.OracleDataSourceFactory"
name="jdbc/db1"
password="xxx"
type="oracle.jdbc.pool.OracleDataSource"
url="jdbc:oracle:thin:@xx:xx:xx"
user="xx"/>
</Context>
...this new Context.xml doesn't work. I get the following:
javax.naming.NamingException: Cannot create resource instance
at org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFactory.java:132)
at javax.naming.spi.NamingManager.getObjectInstance(Unknown Source)
at org.apache.naming.NamingContext.lookup(NamingContext.java:792)
....any ideas? Almost seems as if the "factory" attribute of <Resource> is not being used.
thanks

Solved: Context.xml Resource difference between 5.0.x and 5.5.x?
Posted by TomK <sw...@yahoo.com>.
Solved. Crazy but true.
When using the Oracle factory:
In a Tomcat 5.0 context file, the "url" parameter (name, not the value) must be lower case. In a Tomcat 5.5 context file, the "url" parameter must be UPPER CASE.
Works now. Thanks for the help. Sorry for so many mails...

The docs say that the factory parameter is only needed for entries that

context) and not the standard one used by Tomcat you will need to have the
factory element in place.
See:
http://jakarta.apache.org/tomcat/tomcat-5.5-doc/config/globalresources.html
Under Resource Definitions it says:
"You MUST also define any other needed parameters using attributes on the
Resource element, to configure the object factory to be used (if not known
to Tomcat already), and the properties used to configure that object
factory."
And since Oracle does not use the standard factories that are built into
Tomcat you will need the parameter for factory.
And I could be full of manure and sprouting daisies. But every now and then
I get one right.

The docs say that the factory parameter is only needed for entries that
Tomcat is not "aware" of. Since you had a special factory(in your old 5.0
context) and not the standard one used by Tomcat you will need to have the
factory element in place.
See:

Under Resource Definitions it says:
"You MUST also define any other needed parameters using attributes on the
Resource element, to configure the object factory to be used (if not known

factory."
