Creator App Tomcat Deployment Problem

Question

I am trying to connect to a datasource in Tomcat and then access that datasource with my webapp here is the entry in server.xml
SERVER.XML
<Context path="/Login" docBase="Login"
        debug="5" reloadable="true" crossContext="true">
    <!-- maxActive: Maximum number of dB connections in pool. Make sure you
         configure your mysqld max_connections large enough to handle
         all of your db connections. Set to 0 for no limit.
         -->
    <!-- maxIdle: Maximum number of idle dB connections to retain in pool.
         Set to -1 for no limit.  See also the DBCP documentation on this
         and the minEvictableIdleTimeMillis configuration parameter.
         -->
    <!-- maxWait: Maximum time to wait for a dB connection to become available
         in ms, in this example 10 seconds. An Exception is thrown if
         this timeout is exceeded.  Set to -1 to wait indefinitely.
         -->
    <!-- username and password: MySQL dB username and password for dB connections  -->
    <!-- driverClassName: Class name for the old mm.mysql JDBC driver is
         org.gjt.mm.mysql.Driver - we recommend using Connector/J though.
         Class name for the official MySQL Connector/J driver is com.mysql.jdbc.Driver.
         -->
    <!-- url: The JDBC connection url for connecting to your MySQL dB.
         The autoReconnect=true argument to the url makes sure that the
         mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
         connection.  mysqld by default closes idle connections after 8 hours.
         -->
  <Resource name="jdbc/MySQL" auth="Container" type="javax.sql.DataSource"
               maxActive="100" maxIdle="30" maxWait="10000"
               username="jasonwpalmer" password="788721" driverClassName="com.mysql.jdbc.Driver"
               url="jdbc:mysql://localhost:3306/ElegantMailing?autoReconnect=true"/>
</Context>JARS
I have uploaded the appropriate .jars to tomcat5/common/lib
Jakarta-Commons DBCP
Jakarta-Commons Collections
Jakarta-Commons Pool
Connector-J
(When I looked at the .properties file it looked like all .jars in this directory are automatically added to classpath so I don't think the problem is with the classpath.
Now here is where I thnik I might have the problem, here is the code in my app to make the connection...
private void _init() throws Exception {
        loginRowSet.setDataSourceName("jdbc:mysql://localhost:3306/ElegantMailing");
        loginRowSet.setCommand("SELECT * FROM login");
        loginRowSet.setTableName("login");
        loginDataProvider.setCachedRowSet((javax.sql.rowset.CachedRowSet)getValue("#{SessionBean1.loginRowSet}"));
    }I'm thinking maybe I have the url wrong, but i really don't know. Here is the exception...
System Messages Cannot read LOGIN database: java.sql.SQLException: JdbcRowSetXImpl (connect): (JNDI) Unable to connect: Name jdbc:mysql: is not bound in this Context
Anybody Please Help I'll gladly give up 5 Duke Stars to the person that helps me out.

Answer 1

No the name of the database is ElegantMailing and from what I have learned we need to set a database url, not a url leading to the MySQL server. But if you thought I named my database MySQL then that would make sense, but I was making the same mistake. I was having such a hard time hooking my app up to datasource in Tomcat and that was one route I tried, changing the url in my app 999 times, this is a mistake, Creator does it right by default and all you have to do is set the datasource up in Tomcat Admin.
Make sure that you have the right driver installed in...
<Tomcat Install Dir>/common/lib
I used latest Connector/J with DBCP Connection Pooling.
Then you need to deploy your app to Tomcat I used the Tomcat/manager/html to deploy (if you have a hosting company that doesn't give you your own VPS with your own instance of Tomcat to configure however you like then get one because your on your own with this one(Search Eapps Hosting they're awesome, they even went so far as to install a .jsp that connected to MySQL for me!!!!!!!)).
After you deploy, do not launch app. Launch Tomcat Admin and then go to the left hand menu bar click the little goofy looking thing next to Service (Catalina) (For 3 days I didn't even know that goofy thing opened up more options, I read a post that said install your datasource right under the app in Tomcat and it took me forever to figure out this is what they were talking about) then you'll see the goofy thing for Host (click the goofy thing) and then you'll hopefully see the context/ for your app - you'll know what I mean when you see it- then you'll see resources, datasources, etc., click datasources. Here's the getcha gotcha, if you see an entry in datasources JNDI Name and JDBC Driver Class both with the names of your datasource and driver, then you're in business, if you don't, then don't bother going any further, something you have done this far is wrong. But, if you see the datasource, then you can click on it and fill in the data here is an example for the latest connector J
Property Value
JNDI Name: jdbc/ElegantMailing
Data Source URL: jdbc:mysql://localhost:3306/ElegantMailing?autoReconnect=true
JDBC Driver Class:
User Name:
Password:
Max. Active Connections:
Max. Idle Connections:
Max. Wait for Connection:
Validation Query: select * from login
This is only an example and if you are not using connector j then the ?autoReconnect=true part will probably be omitted. Also you need to know that there are 3 supporting jars for the connection pooling for connector j they are:
Jakarta-Commons DBCP
Jakarta-Commons Collections
Jakarta-Commons Pool
It is important to mention that I read a post that said after you configure datasource go back out to main menu and do it again in the root menu datasources, I do not know if this is necessary, but I did it just in case. Make sure you use the same entries.
If you follow these directions it really should work, here is a Tomcat link that walks you through everything I just explained. This is really hard if you never did it before, but believe me the first time this works and it all comes together, you're gonna feel like a million bucks. Hope this helps!
