Hi folks,
Sorry to bring back this issue.... I still cannot make my connection
pooling to work... arrrgghh...
I got the configuration as stated in email below.. except my path is
empty ("").
I created a simple java test and inside the main(), I just call the
DatabaseOperation class
and it should initialize all the connections. The error I got as
follows:
javax.naming.NoInitialContextException: Need to specify class name in
environment
or system property, or as an applet parameter, or in an application
resource file:
java.naming.factory.initial
at javax.naming.spi.NamingManager.getInitialContext(Unknown Source)
at javax.naming.InitialContext.getDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.getURLOrDefaultInitCtx(Unknown Source)
at javax.naming.InitialContext.lookup(Unknown Source)
at com.maxis.app.DatabaseOperation.initialConnection
I've specified the <name>driverClassName</name> in server.xml. Isn't
this value
loaded in my environment/system property? What is application resource
file?
Any ideas/suggestions?
BTW, if I use Class.forName("com.mysql.jdbc.Driver");
DriverManager.getConnection("....") coding, that works fine..
I can connect to database.
Thanks,
--Kawthar

If I could see the error it would help but I don't think your
datasource is
getting loaded correctly into JNDI. The full name of the jar in
common/lib
works fine.
Here is the context.xml I used based on the HOW_TO and it works
great. If this file doesn't work, it is most likely a location or
alternate
error.
<Context path="/DBTest" docBase="DBTest"
debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger"
prefix="localhost_DBTest_log." suffix=".txt"
timestamp="true"/>
<Resource name="jdbc/TestDB"
auth="Container"
type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/TestDB">

Yes, I have the latest connector inside my /common/lib.
mysql-connector-java-3.0.11-stable-bin.jar
I even tried naming this without the word "stable" in it, and still
not
working.
In my log file, I can see the following:
Creating JNDI naming context
Resource parameters for jdbc/mySQLDatabase =
ResourceParams[name=jdbc/mySQLDatabase,
parameters={url=jdbc:mysql://localhost:3306/ecpa?autoReconnect=true,
serverName=localhost, maxActive=100,
drvierClassName=com.mysql.jdbc.Driver, removeAbandoned=true,
username=root, factory=org.apache.commons.dbcp.BasicDataSourceFactory,
password=xxx}]
ResourceRef[className=javax.sql.DataSource, factoryClassLocation=null,
factoryClassName=org.apache.naming.factory.ResourceFactory, .....<same
info as above>]
Do you see anything strage? The factoryClassLocation is NULL.. is
this
a problem?
Thanks,
