Hi,

I am trying to run the "Cat" Quickstart example with TomCat 4.1.27.

I get this exception:
<from browser>
javax.servlet.ServletException: Could not find datasource: Name jdbc is not bound in this Context
at net.sf.hibernate.examples.quickstart.TestHibernateServlet.doGet(TestHibernateServlet.java:48)

at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247)


<from Tomcat console>

19:54:46,916 FATAL DatasourceConnectionProvider:47 - Could not find datasource: java:comp/env/jdbc/quickstart

at org.apache.naming.SelectorContext.lookup(SelectorContext.java:183)

I have add the <Context path="quickstart" docBase="/quickstart"> in my Tomcat server.xml according to the QuickStart Document.

And I check my database connection parameters to make sure they are correct (I use the same parameters in a DB tool and I am able to connect).

Can someone please help me how to resolve this issue?

I am able to get further, now I can't create a connection to the database.

again, I have added the following in my server.xml of Tomcat:
<Context path="quickstart" docBase="/quickstart">
<Resource name="jdbc/quickstart" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/quickstart">
<parameter>
<name>factory</name>

</parameter>

Thats a fascinating new Tomcat/DBCP exception I've seen in the last couple days too! I've never seen it the years before and I'm sure the Quickstart works. I'll check that soon and post an update. I suggest you start with a fresh Tomcat (untar from distribution!) and make sure you don't have any JARs copied to the common/lib, only the single jdbc-driver.jar!

I copy the Jakarta Commons DBCP and Pool (version 1.0) Jar to common/lib of my Tomcat install directory.

But it does not work even when I remove those jars.

Please read my suggestion again. Start with a fresh Tomcat and don't mess around with your broken setup.

Thanks for your suggestion again. I switch a fresh 4.1.24 tomcat, but it still does not work.

I got this exception:

Here is what I add in my tomcat server.xml:
<Context path="quickstart" docBase="/quickstart">

<Resource name="jdbc/quickstart" scope="Shareable" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/quickstart">

I appreciate if you have more suggestion.

I find this IllegalArgumentException in my tomcat log:
java.lang.IllegalArgumentException: Document base C:\JavaSandbox\jakarta-tomcat-4.1.24-LE-jdk14\webapps\quickstart does not exist or is not a readable directory

Do I need to create a directory \webapps\quickstart manually?

It would seem that you should either have docBase="quickstart" or docBase="C:\JavaSandbox\jakarta-tomcat-4.1.24-LE-jdk14\webapps\quickstart" or no docBase. I have not used the JNDI support for MySql in a while but I looked at an old configuration and I used <name>DriverName</name> rather than <name>url</name>. I also use the newer driver rather than the gjt driver, but that is obviously not causing your problem.


[quote="yinglcs"]

Here is what I add in my tomcat server.xml:
<Context path="quickstart" docBase="/quickstart">

I am getting the same error and have tried all the above suggestions. How did you finally fix the issue and what was causing the problem?
