The error you are getting is the JSP parser mistaking the data "<%=
application.getInitParameter(" as the value for the driver parameter of the
sql:setDataSource tag. Then it reports a parsing error as the next parameter
is sees is jdbc.driver with no '=', and hence no value, after it.
If you really want to set up a datasource this way try:
<sql:setDataSource
driver='<%= application.getInitParameter("jdbc.driver") %>'
url='<%= application.getInitParameter("jdbc.url") %>'
user='<%= application.getInitParameter("jdbc.username")" %>'
password='<%= application.getInitParameter("jdbc.password")" %>'
var='db' />
Note the single quotes. This should work as there's nothing wrong with how
you are accessing the init params.

Subject: error accessing a context-param from web.xml
Hi,
I am fairly new to using Tomcat. I am attempting to use a centralized
location to define the MySQL access configuration info. It is my
understanding that the /WEB-INF/web.xml is the best location to store
this info.
I have defined a set of JDBC parameters such as the driver info shown
below in my web.xml file for the web app:
<context-param>
<param-name>jdbc.driver</param-name>
<param-value>com.mysql.jdbc.Driver</param-value>
</context-param>
...
Within a JSP file, I attempt to get the parameter via the implicit
application variable:
<sql:setDataSource
driver="<%= application.getInitParameter("jdbc.driver") %>"
url="<%= application.getInitParameter("jdbc.url") %>"
user="<%= application.getInitParameter("jdbc.username")" %>"
password="<%= application.getInitParameter("jdbc.password")" %>"
var="db" />
Unfortunately, I receive the following error:
org.apache.jasper.compiler.ParseException:
/search-all-cables.jsp(10,56) Attribute jdbc.driver has no value
at
org.apache.jasper.compiler.JspReader.parseAttributeValue(JspReader.java:563)
...
FYI, I am using Tomcat 4.0.4 with J2SDK 1.4.0_01.
Thank you,
Michael
