Subject RE: Problem confinguring MySQL JNDI Datasource RH Linux 7.2
Date Fri, 01 Aug 2003 11:15:24 GMT
Well, at first glance it appears that you are using an incorrectly named
parameter for the DataSource implementation that you are now using.  The
link you provided states that you need to provide a parameter named "user";
however, you are still using the "username" parameter that I provided in my
example.  Try changing this to "user".

Thanks,

Scott,

I tried your suggestion and I am still getting the same error.

Below is the log from the context DBTest, which I setup to use the
datasource.

I tried another suggestion from following URL:

http://www.java-internals.com/code/resourcefactory/readme.html

which also defined the datasource <GlobalNamingResources> section and got a
little further.

The java-internals suggestion uses a different resource type and added a
factory parameter that references a jar file that I had to install in
$CATALINA_HOME/common/lib/

After tryig their suggestion I following error:

java.sql.SQLException: Invalid authorization specification: Access denied
for user: 'nobody@127.0.0.1' (Using password: YES) error
at com.mysql.jdbc.MysqlIO.doHandshake(MysqlIO.java:659)
	at com.mysql.jdbc.Connection.createNewIO(Connection.java:1562)

	at

	at foo.DBTest.init(DBTest.java:23)

Doesn't look like my user and password parameters are getting processed

Here are the sections I updated:

<ResourceLink name="jdbc/MySQLConnectPool"
	                      global="jdbc/MySQLConnectPool"
 
type="com.mysql.jdbc.jdbc2.optional.MysqlConnectionPoolDataSource" />

                    </parameter>

You certainly can define your MySQL JNDI Datasource within the
<GlobalResourceParams> node in server.xml.  This is how I have it set up
currently and everything works fine (I am running Tomcat 4.1.24).  I sent
the following out the other day in response to a different thread, but it
applies here as well:

    The global DataSource definition
    --------------------------------

        <!-- Global JNDI resources -->
        <GlobalNamingResources>

            <!-- Editable user database that can also be used by JNDI
DatabaseRealm to authenticate users -->
            <Resource name="jdbc/MySQLConnectPool" 
                      auth="Container" 
                      type="javax.sql.DataSource" />

            <ResourceParams name="jdbc/MySQLConnectPool" >
			
                <parameter>
                    <name>username</name>
                    <value>????????</value>
                </parameter>

                <parameter>
                    <name>password</name>
                    <value>????????</value>
                </parameter>

                <parameter>
                    <name>driverClassName</name>
                    <value>com.mysql.jdbc.Driver</value>
                </parameter>

                <parameter>
                    <name>url</name>
                    <value>jdbc:mysql://<your IP here>:3306/<your DB name
here>?autoReconnect=true</value>
                </parameter>
				
                <parameter>
                    <name>removeAbandoned</name>
                    <value>true</value>

                <parameter>
                    <name>removeAbandonedTimeout</name>
                    <value>60</value>

                    <value>true</value>
                </parameter>
				
                <parameter>
                    <name>maxActive</name>
                    <value>200</value>
                </parameter>
				
                <parameter>

                    <value>30000</value>
                </parameter>

                    <name>maxWait</name>
                    <value>100</value>
                </parameter>
				
            </ResourceParams>

        </GlobalNamingResources>


    Realm definition using global DataSource
    ----------------------------------------

        <Realm  
            className="org.apache.catalina.realm.DataSourceRealm" 
            dataSourceName="jdbc/MySQLConnectPool"
            userTable="customers" 
            userNameCol="customer_username" 
            userCredCol="customer_password"
            userRoleTable="roles" 
            roleNameCol="role" 
            debug="0"
        />


    Context reference to global DataSource
    --------------------------------------

        <ResourceLink name="jdbc/MySQLConnectPool"
                      global="jdbc/MySQLConnectPool"
                      type="javax.sql.DataSource" />
						  

Hope this helps!!

Thanks,

Scott Stewart

Is that server.xml snippet in <GlobalResourceParams> or its own
<Context>? It needs to be in its own <Context>. Also, where are your
username and password defined? I'm using 4.1.24, and I get a message in
catalina.out if I leave those out (they should be defined in the
<ResourceParams> as parameters). According to some other questions I've
seen about this, that error often comes up due to a permissions problem
with MySQL - does the user you're using have access rights (in MySQL)
for the db?
