also make sure the jsp file compiles ..you should see the java file show up in %TOMCAT_HOME%\work\Catalina\localhost\webapp\org\apache\jsp\index_jsp.java
A crude way to precompile your jsp is to invoke the JspC class directly as in java -cp %TOMCAT_HOME%\common\lib org.apache.jasper.JspC NameOfJsp.jsp Maybe David or someone else can make a recommendation on alternative jasper compilers (and of course make sure you have read permission to those files.)
