My own (particularly uninformed) opinion is that most scripting languages that have wanted to get into JVMs/app servers have simply built their own technologies to handle everything, so it doesn't run through JSP itself. For example, Lucee[1] is a CFML implementation in Java, but it doesn't (always) use JSP. They have a separate "interpreter" for it instead of building huge tag libraries to fit it into JSP. (I say "interpreted" because I don't know if they actually interpret the files each time on demand, or if there is a compilation step at some point. It doesn't really matter either way.) I haven't looked at it in depth, but I believe this is also what Apache JGroovy[2] does. - -chris [1] https://lucee.org/ [2] https://groovy-lang.org/ -----BEGIN PGP SIGNATURE----- Comment: Using GnuPG with Thunderbird - https://www.enigmail.net/ iQIzBAEBCAAdFiEEMmKgYcQvxMe7tcJcHPApP6U8pFgFAl2ePvcACgkQHPApP6U8 pFjuVw//YHtKewJlqmJWTG4raTCOyXMCJLpCcdrkfkWADXsNncVgdY6vPn0csy0d 7eFYLC9oo6XqnLPJDmHZusRiFCcCTNaQTqJts1tvwWnTi79+eR8tupyWCfD9UQGR Ozkil81G1ABtv81ILGbMjiiXVWgiXZERE7i7PMhrR++zR/T1CiC/FTA3q+kDsTtd 6lKzrsXmjoovDts69czovZulO4jMz7A53Ejs8L3Cubx+CO7UIRyH21pEY9CkvfgW DhBjpiSiVNuixoMLHLQakuarxvSFY7+u7s9kollu4JbLalplDc4wgZx7DEn6SGzo i0QZsGPnybkKHMnTUDTOuFozPFYkCuWccJ+SiP+VaEv6B5IlPg53Kq5SfvpcAS5l Tslu/a9yI27AXCmawkD8uX7cFk/B0hK3QBHAWfu4WbvGEvZZjg5QQY4ztHNL4KyC eBBayPpw0z6hf/sP28YjCEPt4s/Z1tqY1UDFKn3zcbiou8j85PsKmwcdC3tpwkLE q3zqTcGStAU9lp41cnT4XXohnjJ0UKFae6ZE+f/TIDbkusc+ToKFEw2Xo3VbImBN 3Qvi1CHIfPMYMzgYBsmddfnWlJwZcfyfhvSXuajI5ogqeZfRJ7aa/HvU101Irzek BEu6A/FZG6woIlkRJ4wVrtddyds1MpCWq31F7XG7WiTzzV8pFH8= =i23J -----END PGP SIGNATURE----- --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
