I was interested by this.
So:
private Service service;
@Override
public void init() throws ServletException {
super.init();
service = (Service)
WebApplicationContextUtils.getWebApplicationContext(getServletContext()).getBean("service");
}
protected void processRequest(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
service.logHit(request);
}
is a bad thing?
Could you explain why?
I would assume that a new request object is created each time, and
that while something has a reference to it, it will be fine, and when
logHit has finished with it, it will be eligible for garbage
collection.

Re: Adding a webapp via the API to a running instance
Reading org.apache.catalina.startup.Tomcat.addWebapp(Host, String,
String, String), I don't understand the following:
// prevent it from looking ( if it finds one - it'll have dup error )
ctxCfg.setDefaultWebXml("org/apache/catalin/startup/NO_DEFAULT_XML");
Why is this being used to prevent the code from seeing a web.xml in
the basedir/conf?

That depends on what Service.logHit does. If it only uses the
HttpServletRequest object during the method's lifetime, then everything
is fine. If it retains a reference to the request object, you will
probably end up with a problem.
> Could you explain why?
Tomcat re-uses the same request and response objects for a long time,
and so multiple request processor threads will see the same object over
the life of the server. If any of that code retains a reference to the
request, by the time the object is re-referenced by the same code for
whatever reason, the object will have "moved on" and will almost
certainly be invalid (from the perspective of the code that cached it)
and might /actually/ be invalid (because it is between requests and
Tomcat has actively invalidated it).

A servlet named jsp
This is related to another thread I started, but it's a different question. Some experimentation shows that Tomcat.java disables the default web.xml for a good reason; if I force one back into place, I get a duplicate name error. However, whatever it ends up using does not include a servlet named 'jsp', and then org.apache.catalina.startup.ContextConfig.convertJsps(WebXml) ends up with an NPE with a webapp (in this case solr) that has any jsp servlets.

[cluster] jvmRoute question
Hi, To take a tomcat instance out from a cluster, now I have a no-cluster.xml and in content it is exactly the same as the server.xml, except the tag is commented out. The question is should I also take out the jvmRoute="tc24x" variable from the tag or leave it there. My workers.properties file remain the same whether a tomcat instance is member of a cluster or not, so I incline to leave it there. On the other hand I did testing as this variable was removed and I have not experienced any problem. The hierarchy is Server > Service > Engine > Cluster Any good suggestion is highly appreciated.

I'd say it is not.
Have a look at ourr test suite. It uses the jsp servlet without
programmatically configuring. I'm pretty sure it comes from the global
web.xml. The test suite also logs
... org.apache.catalina.startup.ContextConfig webConfig
... INFO: No global web.xml found
but that doesn't keep it from executing JSPs.
For instance TestAbstractHttp11Processor deploys test/webapp-3.0 and
calls /echo-params.jsp. The basics are in TomcatBaseTest.
So I'd say there's something wrong in your setup.
HTH.

All it does is adding the value of the jvmRoute attribute at the end of each session ID. Usually it is used by load balancers to implement stickyness, e.g. sending follow-on requests for the same session to the node on which the session was generated. If there's no load balancing involved in routing to theis node, then you won't need the jvmRoute - but it won't hurt either.

Re: Adding a webapp via the API to a running instance
Hi, I set up a testcase at

is NOT a 3.0 webapp. I read the code, and the failing path is in the
if statement for 'pre-3.0'. Please have a look at the single Java

Re: Adding a webapp via the API to a running instance
Ranier,
I don't have a problem executing jsps. I have a problem configuring a
webapp with entire servlets defined by jsps. My code works perfectly
fine launching another webapp with jsps in it which are not declared
in elements.

Running an old servlet with Tomcat 7.0.16 embedded API
Ranier,
I've now demonstrated that this is not about 'deferred launch' but
rather about an old servlet failing to be configured with the embedded
Tomcat class.
https://github.com/bimargulies/Tomcat-Solr-Test-Case
has been simplified. It makes the few required calls to set up the
Tomcat object. Then it calls addWebapp for the solr webapp, and it
failed with an NPE, due to the lack of the 'jsp' servlet from the
usual global web.xml.
The test cases you mentioned didn't bear on this case at all, I'll
look for some others.

Slower start with Tomcat 7.0.14 and higher
Start up takes around 20 seconds longer with Tomcat 7.0.14 and 7.0.16 than it did with 7.0.12. This appears to be due to time spent scanning jars for annotations, etc. We have a number of /very /large jar files in both the base classloader for Tomcat (which we're embedding) and in our web apps. This raises 2 questions: 1. Was jar scanning not working for such uses cases in 7.0.12, e.g. was the scanning incomplete? 2. Did something change to make the performance of the scanning perform much worse in 7.0.14 /and /7.0.16 than in 7.0.12? * The release notes suggest that 7.0.14 had an issue and that it was resolved in 7.0.16, but we're seeing both 7.0.14 and 7.0.16 being approximately equally slow to start up. Clearly the answer to both questions could be "yes". If only #2 is a "yes", then I'd really like to get this resolved and get back to the previous performance. If, however, #1 explains much of the degradation, then I'll need to look into excluding jars from scanning, etc. -- Jess Holle

It should have improved for the majority of use cases in 7.0.14 but at the price of making it worse for JARs in CATALINA_[HOME_BASE]/lib. 7.0.16 should have returned scanning of JARs in CATALINA_[HOME_BASE]/lib to the pre 7.0.14 performance levels. > * The release notes suggest that 7.0.14 had an issue and that >it was resolved in 7.0.16, but we're seeing both 7.0.14 and >7.0.16 being approximately equally slow to start up. > > Clearly the answer to both questions could be "yes".

Tomcat6/7 virtual hosting - yet again
This is my 4th day trying to setup virtual hosting on Linux-Debian; even trying Tomcat6 after failing on Tomcat7. Yes I have read everything that I can find in Tomcat documentation - including the obtuse: http://tomcat.apache.org/tomcat-7.0-doc/virtual-hosting-howto.html what I found on this forum for March: http://mail-archives.apache.org/mod_mbox/tomcat-users/ as well as all as many, many well intended explanations located on the Web. Please acknowledge my stupidity, but help anyway. This is long indeed. On purpose. I believe we need a detailed description how to do it correct. Note, I do NOT use WAR-file deployment. [It is not clear to me whether that is relevant ...] I test using a windows XP box which allows to create a bogus domain in the file: C:\WINDOWS\system32\drivers\etc\hosts It has the line: 206.41.127.116 www.testzzz.com Using a browser (on that box) to access that bogus domain www.testzzz.com "works" but gives an unexpected response: Index of / [ICO] Name Last modified Size Description Apache/2.2.9 (Debian) Server at www.testzzz.com Port 80 The site, apparently, was able to get to the right place, but ... I expected to access an index.html file under a ROOT directory, see below. Here the testzzz directory structure: /home/ddc/test /home/ddc/test/ROOT /home/ddc/test/host-manager /home/ddc/test/manager /home/ddc/test/ROOT/index.html /home/ddc/test/ROOT/WEB-INF /home/ddc/test/ROOT/WEB-INF/web.xml No, there are no errors in catalina.out. That log does have a line showing that ROOT.xml is activated: INFO: Deploying configuration descriptor ROOT.xml I do NOT see deployment of www.testzzz.com. Under webapps/ I see auto generated directories for: ROOT, docs, examples, host-manager, manager In logs, I see empty logs for: manager host-manager localhost testzzz access log I expected that the testzzz log would grow. Here is what I have in server.xml (pruned): Under .../Catalina: www.testzzz.com www.testzzz.com/ROOT.xml www.testzzz.com/manager.xml www.testzzz.com/host-manager.xml Inside ROOT.xml: Now what?

Christopher, and also Konstantin and Martin, thank you for your postings on this. As it happened, my original code that crashed, and from which I derived the demo code that I posted, had a bug. I do put a reference to the response into an instance, in order that I can give my main processing method all the data it needs (including the response) as one single parameter. But I'd intended to put the response into this instance every time my JSP is accessed, and not merely the first time. Until you pointed it out, I didn't notice that I wasn't, even with my simplified code. So thanks for that. That said, I think I was expecting that it wouldn't matter, since the response "ought" to be the same instance on each processing cycle anyway.

Is this correct behaviour or some bug?

Setting SSL for login pages
So guy, I want the user to be redirected to HTTPS once he hits an authenticated page. So I think it would be natural something like this: SSL login /login/* CONFIDENTIAL FORM MyRealm /login/login.jsp /login/error.jsp The problem is the FormAuthenticator Valve uses a forward, so the URL used is the one of the target page, not the login page. That means that the /login/login.jsp URL is never requested and the security constraint is never applied. The same way an Apache HTTPD proxy can't know whether the request resulted in a login page or not. As I see, the way it is, all authenticated pages must be set to CONFIDENTIAL also (in case the user is not authenticated and ends up in the login page). But if the user IS authenticated he is forced to use HTTPS too, and that I was trying to avoid. Am I missing something? -- Rafael Liu +55 61 9608-7722 http://rafaelliu.net

No problem.
If you need all your data from scratch, anyway, why bother caching
anything at all? If your data is always ephemeral, these issues
evaporate and your code (often) becomes cleaner, too.

I would actually expect something different: that Tomcat always gives me
a brand new, never-before-used and never-to-be-used-again object. The
fact that Tomcat plays some tricks to reduce heap churn (that is,
allocating/initing/deallocating lots of "temporary" objects) should be
entirely transparent to the webapp if it's playing by the rules. The
servlet spec clearly states that the request and response objects are
only valid during a particular transaction.

Ignorance of the spec will certainly cause a lot of "surprises" :)
I'm not convinced that this should be surprising, anyway.
If I write a method like this:
public void foo(Bar bar)
{
...
}
Why should the method foo() expect that each invocation will always have
the same Bar object passed-into it?
By extension:
public void doGet(HttpServletRequest req, HttpServletResponse rsp)
{
...
}
Should this one be treated any differently?
If the object is always going to be the same, why bother having it as a
parameter instead of part of the object's state?

Think about it: if the secure traffic is only for the login page, anyone could access the not-really-protected pages by sniffing the sessionid used on the unsecure connection - you would have no security. - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

I see the same behavior with this simple JSP in Tomcat 6.0.32:
<%
response.setHeader("Last-Modified", "Tue, 15 Nov 1994 12:45:26 GMT");
response.setHeader("X-Test-Header", "12345");
response.setHeader("Connection", "close");
response.setHeader("Content-Location", "http://www.google.com/";);
response.setHeader("Vary", "Content-Length");
response.setHeader("Expires", "Tue, 21 Jun 2011 12:00:00 GMT");
response.setHeader("Cache-Control", "foo");
response.setStatus(304);
%>
Neither Last-Modified nor X-Test-Header come back to my browser, though
I was able to set the Connection, Content-Location, Vary, and Expires
headers.
> Is this correct behaviour or some bug?
Looks like httpd is following the spec while Tomcat is not:
http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5
Specifically:
"
If the conditional GET used a strong cache validator (see section
13.3.3), the response SHOULD NOT include other entity-headers. Otherwise
(i.e., the conditional GET used a weak validator), the response MUST NOT
include other entity-headers; this prevents inconsistencies between
cached entity-bodies and updated headers.
"
Read that very carefully: basically, no entity-headers other than those
explicitly mentioned in that section (Date, ETag, Content-Location,
Expires, Cache-Control, Vary) "RFC SHOULD" be returned under any
circumstances, and, in most circumstances entity-headers other than
those "RFC MUST NOT" be sent.
If anything, I'd say that Tomcat was out-of-spec by allowing those
additional headers to get through.

RE: Setting SSL for login pages
Good point Chuck. I agree with you, the webapp wouldn't be all secured. But there are 2 different things here: * the issue with the plain password * the issue with session hijacking The first one first gives the hacker a private information about the user (which can even the used by the user somewhere else). The hacker will have the actual user's credentials, and will be able to login at will. The second one doesn't necessarily exposes user's informations. The hacker can pretend to be the user, but only for the time of the session. Even tho there are tricks to keep the session alive [almos] forever, this is essentially different from having the user's credential. I see them at different levels of security. Using the same logic, one can say that there's no point in using DIGEST authentication if there's still room for session hijacking. Much like BASIC / DIGEST or CONFIDENTIAL / INTEGRAL provides different levels of security, I think the two cases mentioned also do.Giving these kind of options to the webapp can make NFR (like performance) easier to meet and infrastructure easier to configure (like rewriting on Apache). What do you think?

Here's a reasonably detailed description for the Tomcat part (using Tomcat 6.0.26 on Fedora and Windows). http://wiki.apache.org/tomcat/TomcatDevelopmentVirtualHosts I've not written up how to map this to Apache HTTPD virtual hosts, but basically that should just be placing the right JkMount directives in the correct Apache HTTPD virtual hosts. As other people have pointed out, if you want to access your web sites on port 80, you'll either have to use something like mod_jk, mod_proxy_ajp, or mod_proxy_http with Apache HTTPD. Or you can shut down your Apache web server and change Tomcat to run on port 80.
