I'm sorry, but I must object :-). This isn't how to get init-param's
working with JSP, so it's not a solution -- and I wouldn't even call
it a workaround, because you don't need to do a workaround. What I
said in a previous note should work. I constructed an example to
demonstrate it.
Here's the relevant stuff from the web.xml file (which is located in
<path-to-tomcat>/webapps/blah/WEB-INF/):
<servlet>
<servlet-name>testy</servlet-name>
<jsp-file>testy.jsp</jsp-file>
<init-param>
<param-name>var1</param-name>
<param-value>value1</param-value>
</init-param>
<init-param>
<param-name>var2</param-name>
<param-value>value2</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>testy</servlet-name>
<url-pattern>/testy.jsp</url-pattern>
</servlet-mapping>
I've appended the JSP after my sig.
I used a URL of the form:
http://my.domain.com/blah/testy.jsp
The only thing I had trouble with was where the test.jsp file should
go. I tried it in <path-to-tomcat>/webapps/blah/WEB-INF/classes/, and
it didn't work. I put it in <path-to-tomcat>/webapps/blah/, and it
did work. I'm not sure I fully understand why that is, but at least I
did get the init-param's working.
