Resource - Cannot load JDBC driver class 'null'

2003-01-08 Thread afterz 
Hello,
I created a DataSource(jdbc/SAA) through Tomcat
 Administration and put into my web.xml:

resource-ref
descriptionDownload example/description
res-ref-namejdbc/SAA/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref

But when I try to use it I get the following error:

java.lang.Exception: java.sql.SQLException: Cannot load
 JDBC driver class 'null'

Tomcat changed by itself the server.xml with many things
 like:

Context
 className=org.apache.catalina.core.StandardContext
 cachingAllowed=true
 charsetMapperClass=org.apache.catalina.util.CharsetMapper
 cookies=true crossContext=false debug=0
 docBase=D:\java\jakarta-tomcat-4.1.12\webapps\sampleFilters
 mapperClass=org.apache.catalina.core.StandardContextMapper
 path=/sampleFilters privileged=false
 reloadable=false swallowOutput=false useNaming=true
 wrapperClass=org.apache.catalina.core.StandardWrapper
Resource auth=Container description=Download example
 name=jdbc/SAA scope=Shareable
 type=javax.sql.DataSource/
/Context

I searched other lists and found out that many people had
 this problem, but I found no soulution.
Could somebody help me?

Thanks.
Ricardo Costa.

Note that there are no nested elements inside the Context.  That implies
that you created the new data source in the global resources area.  To
make it visible to a webapp, you also need to create a Resource Link
inside the Context, by highlighting this context in the tree and
selecting the add resource link action.
