hey buddies
i'm a newbie to the JSP arena.... i've just come to custom tag
development.... i'm getting mad in deploying a sample app.... btw i'm using
tomcat 3.2.1 server...
is there any strict naming convention for the tld file if so plz specity
it....
i'm providing u source for web.xml, tld file ,tag handler(.java) and jsp
file with this..
the directory structure which i'm having now is as follows:
sample web application context path is : /gen
tld file is in : /gen/Meta-Inf/GenTag.tld
web.xml file is in : /gen/Web-Inf/web.xml
tag handler class file is in : /gen/Web-Inf/classes/GenTag.class
jsp file is in : /gen/test.jsp
btw context path adddr is : <server-root>/webapps/gen
hte error which i'm getting is::
org.apache.jasper.compiler.CompileException:
C:\Jakarta\jakarta-tomcat-3.2.1\webapps\gen\test.jsp(0,0) Unable to open
taglibrary FirstTag : C:\Jakarta\jakarta-tomcat-3.2.1\webapps\gen\FirstTag
(The system cannot find the file specified)
all i want is this sample app should work... what ever u say i'm ready to
accept!!!!
