Why do you need hundreds of c:imports in the same page? That suggests to me that your architecture is not particularly efficient. I would imagine you are using mostly local imports. The JSTL spec says that for internal resources, RequestDispatcher.include should be used. If you are seeing an explosion of threads, then there is either a bug in the JSTL implementation or you are observing unrelated behavior. The servlet spec states that a request will be handled by a single thread from start to finish -- that includes (ha!) includes. I'm pretty sure that Tomcat will not allocate another thread to handle an include, so I wonder if the JSTL is making a bad decision. Are you using only local imports? Whose JSTL implementation are you using, and what version? If you are using external imports, you may have a problem. The JSTL spec states that URLConnection should be used to fetch those resources. URLConnection uses InputStream and OutputStream to handle input and output. IIRC, each stream requires a thread, which means that all your connections are creating lots of threads to manage input and output. Since everything is still in scope (one giant _service method in your JSP), the resources aren't cleaned up as the page executes. In this case, I wonder if splitting a large page into smaller pages might allow these resources to be freed a little more progressively. Let's see what that thread dump shows... - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkgXK0AACgkQ9CaO5/Lv0PCbwwCgvz38DJgs3U9NNjq2yQpfNOaa b0MAoJnS4hBfStGbpj6aqBJNDUAZi38n =vTRQ -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
