Deploying a WAR file to Sun App Server 8.1 PE

Question

So I thought that if I downloaded Sun App Server PE 8.1 and put it on my soon-to-be production machine, it should be pretty easy right?
Nope. So I have JSC update 6 (which includes Sun Application Server 8.0) (God how I wish there was a catchy name like Tomcat or something)
And I have a machine running a good copy, installed and everything, of Sun Application Server 8.1 Platform Edition (another catchy name) up on the production target.
I create a WAR file in JSC, scp it up.
Then try to deploy it - so I get bit by the no DB connection thing.
Ok, but when I copy each of my connection's attributes (the driver (which I did copy up to the lib directory) is MySQL's Connector/J)
I copy the username, password, URL and DriverClass attributes to the connection pool.
I still get a
"Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: Class name is wrong or classpath is not set for : com.sun.sql.datasource.DriverAdapter"
when I try to Ping the ConnectionPool
I have javax.sql.DataSource as the resource type... (same as 8.0 uses)
what JAR file is DriverAdapter in? anyone know?
cheers,

Answer 1

Okay. mysql folks - this works......
here's what happened, on the production server, different from the dev machine....
mysql 4.1.9
sun application server platform edition PE 8.1
connector/j - latest
and on the dev machine: JSC Update 6 and the app works fine on the dev machine.
first, there is a JAR file in ~whatever/Create/SunAppServer/lib/ named
driveradaptor.jar
and it it comtains
com.sun.sql.datasource.DriverAdapter
which 8.1 ain't got
and should be copied up to
/installdir/SunAppServer/domains/domain1/lib/ext/driveradapter.jar
(domain1 is your app svr domain that runs your app.)
your Connector/J JAR needs to go here too. I used:
mysql-connector-java-3.2.0-alpha-bin.jar
downloaded from mysql.com.
and then there is the whole thing about Added Properties in the Connection Pool page inside the 8.1 Admin Console (which is nice work guys). Gawd, I added a bunch of properties and am, frankly, not sure which ones actually work (for the Ping, for the initial connection creation and the eventual successful connection all seem to use different combinations...)
and I found this in the domain's domain.xml once all the admin console page filling was done - but you'll need to add each one as a Property in the connection pool:
<jdbc-connection-pool connection-validation-method="auto-commit" datasource-classname="com.sun.sql.datasource.DriverAdapter" fail-all-connections="false" [blah...]
<property name="Username" value="root"/>
<property name="Password" value="secret"/>
<property name="ValidationQuery" value="SELECT 1"/>
<property name="DriverClassName" value="com.mysql.jdbc.Driver"/>
<property name="LoginTimeout" value="0"/>
<property name="Url" value="jdbc:mysql://localhost/databasename?autoReconnect=true"/>
<property name="User" value="root"/>
<property name="password" value="secret"/>
<property name="PasswordCredential" value="secret"/>
</jdbc-connection-pool>
(and you see how User and Username and username are all the same thing? well, different parts of 8.1 seem to use different attributes...)
Just keep Adding Properties in the connection pool until you get them all....
Oh and, the two key class references for the pool are:
datasource class: com.sun.sql.datasource.DriverAdapter
resource type: javax.sql.ConnectionPoolDataSource
Finally: in the /installdir/SunAppServer/domains/domain1/applications/j2ee-modules/YourAppName/WEB-INF/
your 'sun-web.xml' (don't delete it, like some have advocated, I think that wrong) needs to look like:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sun-web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Application Server 8.1 Servlet 2.4//EN" "http://www.sun.com/software/appserver/dtds/sun-web-app_2_4-1.dtd">
<sun-web-app xmlns="http://java.sun.com/xml/ns/j2ee">
<context-root>/yourcontext</context-root>
<resource-ref>
<res-ref-name>jdbc/Yourname</res-ref-name>
<jndi-name>jdbc/Yourname</jndi-name>
<default-resource-principal>
<name>root</name>
<password>secret</password>
</default-resource-principal>
</resource-ref>
</sun-web-app>
and I think that's all of it. the only Bug I would I would say is that the sun-web.xml should have the right res-ref-name, but then I think the Creator Team knows this and will fix it sometime soon.
