Hi,
I think I have run into a bug with tomcat, but wanted to check with
the user list to make sure it is a bug before I file it.
Background:
I am using the tomact jdbc pool over the dbcp pool and I am embedding
tomcat as part of an application that clients install on their data
centers.
1) delete the lib\tomcat-dbcp.jar from the tomcat\lib
2) Configure a jdbc connection pool in server.xml in the GlobalNamingResource
<GlobalNamingResources>
<Resource
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
auth="Container"
type="javax.sql.DataSource"
jdbcInterceptors="StatementFinalizer;ResetAbandonedTimer"
name="jdbc/testDB"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://127.0.0.1:5432/tes"
username="test"
password="test"
maxActive="20"
maxIdle="10"
maxWait="-1"
/>
</GlobalNamingResources>
3) Add a resource ref to the web.xml
<resource-ref>
<description>Test Datasource</description>
<res-ref-name>jdbc/testDB</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
4) do an a lookup for the data source
try {
InitialContext ctx = new InitialContext();
Object object =
ctx.lookup("java:/comp/env/jdbc/testDB");
System.out.println(object.getClass().getCanonicalName());
} catch (NamingException e) {
e.printStackTrace();
}
5) Tomcat throws an exception java.lang.ClassNotFoundException:
org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory full stack trace
below.
It is not clear why it would be looking for dbcp DataSource when i
have my data source defined using
factory="org.apache.tomcat.jdbc.pool.DataSourceFactory"
Interestingly if the resource is defined in context.xml in META-INF
for the war there are no exceptions it just works.
Any thoughts on whether this is a bug or not?
Cheers,
