by passing virtualhost when accessing an app?
Hi, Say I have app deployed as www.myapp.com, for sake of debugging I'd like to access it without the virtual host approach, maybe just http://127.0.0.1:8080~www.myapp.com, possible?

Tutorial for implementing a valve
Dear all,
I'd like to try something in Tomcat 6, and therefore I have to
implement it as a valve.
I know that I have to implement org.apache.catalina.valve, however, I
got no clue where to start.
- In which jar among all the jars delivered with Tomcat do I find the interface?
- Once having the valve created, where do I put it (will
${CATALINA_HOME}/webapps/${myApp}/WEB-INF/lib be ok)?
- Anybody knows about a tutorial or how-two?
TIA
Gregor

Re: by passing virtualhost when accessing an app?
that's what i'm doing now, i was just hoping maybe there are ways without updating the hosts files, reason is, when you ask somebody to try out your app from a certain website and told them to update the hosts file, 9 out of 10 will not do it, of course this happens only during development when the domain is not yet pointed at the app. Gregor Schneider wrote: Why don't you simple add the entry 127.0.0.1 www.myapp.com myapp.com into your /etc/hosts or *sic* in WIndows into C:\WINDOWS\system32\drivers\etc\hosts?

Perhaps you can make the app available as a subdirectory of a domain, (similar as how google does it) that way you can point them to http://example.com/example.org to access the app you would normally access as example.org Hope this helps, Regards, Serge Fonville On Tue, Jan 6, 2009 at 2:04 PM, Angelo Chen angelochen...@yahoo.com.hkwrote: that's what i'm doing now, i was just hoping maybe there are ways without updating the hosts files, reason is, when you ask somebody to try out your app from a certain website and told them to update the hosts file, 9 out of 10 will not do it, of course this happens only during development when the domain is not yet pointed at the app. Gregor Schneider wrote: Why don't you simple add the entry 127.0.0.1 www.myapp.com myapp.com into your /etc/hosts or *sic* in WIndows into C:\WINDOWS\system32\drivers\etc\hosts?

AFAIK catalina.jar is the place to look.
I think that you probably want to extend ValveBase instead of just
implementing the interface too.
In essence, I've found Valves to be quite similar to Filters at the most
basic level. Adding the Lifecycle interface makes things a little more
complicated.
I pulled the AccessLogValve apart when I first played with them.

RE: Configuring a Realm
From: Charl Gerber [mailto:charlger...@yahoo.com] Subject: Configuring a Realm I know I somehow have to configure the login-config to use my new Realm, but how? No, you don't, other than to indicate the authentication mechanism. The presence of the Realm element inside your webapp's Context should be sufficient to cause Tomcat to use it. There is a tag realm-name which looked to be my answer The realm-name here is not related to the configured Realm, at least for BASIC authentication; as I recall it's used primarily for DIGEST authentication to construct the hash key. The datasource works and can be tested from within the application, so it is set up correctly. Are you using the same database for both application usage and authentication? That's odd, but doable. The application's context.xml: Where is the context.xml file located? Context path=/rankings docBase=path.to.file/rankings.war If the context.xml file is in the webapp's META-INF directory, the path and docBase attributes are not allowed - remove them. Is there a conf/Catalina/[host]/rankings.xml file present? If so, it will override the context.xml in META-INF, meaning your Realm element will be ignored. Is there anything in the Tomcat logs pertinent to the use of the Realm? - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.

replacement for useBean directive
OK I know this isn't Tomcat-specific, but my post on Sun Forums didn't get
much of a reply, so I thought I'd try it here.
I'm in the process of translating a series of JSPs into straightout servlets
and I have a question about how I should replicate the functionality of the
useBean directive in my Servlet.
I have a set of Beans that mediate between the JSP and a database (actually
btwn JSP and a class that accesses the db). These beans cache results from
the database, cutting back on back and forth traffic. They timeout after
varying periods of time, flush their memory (hashmaps) and then reload as
needed.
I've used the useBean directive with no problem, it's just that now the
project has grown in complexity to where it needs to be re-written as a set
Servlets.
My solution for replacing the useBean functionality has been a BeanBag class
with the following form:
class BeanBag {
private static AppleBean appleBean = null;
private static BananaBean bananaBean = null;
public static AppleBean getAppleBean() {
if (appleBean == null) {
appleBean = new AppleBean();
}
return appleBean;
}
. and so on
}
In the Servlet code, I just obtain a bean like this:
AppleBean appleBean = BeanBag.getAppleBean();
My question is: where (or if) should I implement the synchronization?
The generated servlets that Tomcat creates for the useBean directive uses
Synchronized Statements, like this:
synchronized (application) {
appleBean = (com.fruitsalad.AppleBean)
_jspx_page_context.getAttribute(appleBean, PageContext.APPLICATION_SCOPE);
if (appleBean == null){
appleBean = new com.fruitsalad.AppleBean();
_jspx_page_context.setAttribute(appleBean, appleBean,
PageContext.APPLICATION_SCOPE);
}
}
But wouldn't making the methods in BeanBag synchronized be a better
approach?
Thanks

Tomact behind ISA server - session problem
Hi, I have a Tomcat installed behind ISA server. It is properly(?) published, so I can reach it from outside world, as from LAN also. But, when I access my Tomcat application from LAN, all session attributes are fine, the app works as I want it to. When I access it from outside world, something is wrong with session. For example, I access the app from Firefox, exit Firefox, and start IE - the same session(!). On the other hand, I have a Java class as a session object, but sometimes I can not modify it, and sometimes I can. I must emphasize that everything works nice when I access the app from LAN.

Re: Tomact behind ISA server - session problem
My first thought is some kind of caching proxy server. If you aren't the local IT admin, you might want to check with them what might exist on the border between the LAN and WAN. Tomcat itself doesn't treat the local LAN any different than the outside world. From it's perspective, a client is a client regardless of network location. --David Boban Jankovic wrote: Hi, I have a Tomcat installed behind ISA server.

Re: replacement for useBean directive
Thanks Chuck, just one more question: do I really need synchronization at
all?
These Beans basically work like this:
getApple(int appleID) {
purgeIfTimeout(); //calls appleMap.clear() if we've timed out
if (appleMap.containsKey(String.valueOf(appleID)) {
return (Apple)appleMap.get(String.valueOf(appleID);
} else {
Apple a = FruitDB.getApple(appleID); //this is where the database
interaction takes place
if (a != null) appleMap.put(String.valueOf(appleID), a);
return a;
}
}
Is synchronization really called for here, either around the getITEM()
methods inside the beans or around the methods in BeanBag that return the
bean?

Linux 4 Update 7 and Tomcat
Hey Guys, Happy New Year! Being a novice in the world of Apache, I have a quick question regarding Tomcat and Linux 4 Update 7. We are currently running Tomcat version 5.5.23 on Red Hat Linux OS Linux 4 Update 5. Our server team is planning to upgrade Red Hat Linux 4 to version 2.6.9-78.0.8.ELsmp (Red Hat Enterprise Linux 4 (Nahant Update 7)). I was wondering if you are aware of any known incompatibility issues with this mix of Tomcat and Linux or is there something else we should be aware of when upgrading. Any advice would greatly be appreciated. Thank you for your time Thank you, Rob Gonzales Programmer Analyst Limited Brands Technology Services Office 212*884*0840 Mobile 917*796*9018
RE: replacement for useBean directive
From: Jonathan Mast [mailto:jhmast.develo...@gmail.com]
Subject: Re: replacement for useBean directive
do I really need synchronization at all?
Short answer: yes.
Is synchronization really called for here, either
around the getITEM() methods inside the beans or
around the methods in BeanBag that return the
bean?
Yes to both. Your example getApple() shows use of some form of Map, most forms
of which require external synchronization. Even if such Map objects
implemented internal synchronization, the logic that checks for the existence
of the key then retrieves the corresponding value requires that the state of
the Map not change between the containsKey() and get() calls.
BTW, you're creating a ton of throw-away objects by doing String.valueOf(int)
here; you may be better off to keep appleID as a String or Integer throughout.
Also, you don't need the containsKey() call, the get() will return null if the
key isn't present.
synchronized Apple getApple(int appleID) {
purgeIfTimeout(); //calls appleMap.clear() if we've timed out
Apple a = (Apple)appleMap.get(String.valueOf(appleID));
if (a != null) return a;
a = FruitDB.getApple(appleID);
if (a != null) appleMap.put(String.valueOf(appleID), a);
return a;
}
Also, your appleMap should be declared as HashMapString, Apple or
HashMapInteger, Apple (or whatever Map type you're using) so you can get rid
of the casting.
Your BeanBag class methods also need synchronization to close the window
between testing a field for null and then allocating an object for it. Failure
to do so runs the risk of two threads both seeing the field as null, and both
creating beans for the same item type.

RE: Configuring a Realm
No, you don't, other than to indicate the authentication mechanism. The presence of the Realm element inside your webapp's Context should be sufficient to cause Tomcat to use it. That's what I thought, but my Realm is just ignored and the one that is present by default when installing Tomcat is used instead. Are you using the same database for both application usage and authentication? That's odd, but doable. Yes, same datasource. Won't go into the details, but perfectly valid reason for doing so. If the context.xml file is in the webapp's META-INF directory, the path and docBase attributes are not allowed - remove them. Yes, in the META-INF. I removed the path and docBase attributes, but still no joy. Is there a conf/Catalina/[host]/rankings.xml file present? no. Is there anything in the Tomcat logs pertinent to the use of the Realm? No, that was going to be my next question. I see no authentication logging whatsoever. Not even of the default Realm, which has debug=0. I'm baffled.

Oracle database calling the web app?
Is it possible to set up a callback like situation so that a trigger in an Oracle 10g database can call a method in a currently running webapp that's running in Tomcat 6? My situation is that I want to cache some infrequently changed database data in memory but when that data does change in the database, I want the web applications, running on multiple servers, to immediately pick up the change. Right now, one idea I have for this is to have the database trigger create a file in a file system that's shared by the database server and the application servers and have the web apps check for the existence of this file to know whether to update the cache. It feels ugly and means hitting a networked file system a lot but it seems like it should work and it seems like it should not be as bad as hitting the database constantly for something that doesn't change very often.

Re: Oracle database calling the web app?
Whoops, hold that. This is ok for outbound.

RE: j_security_check with https
Howdy, First, to clear an incorrect point made... There is a point of switching back to HTTP after HTTPS. From a server load perspective having to perform SSL computations for every single HTTP request can be a serious performance bottleneck. As for the security aspect, transmission of the username/password should be done over HTTPS, as this is considered private/confidential data and can be used to establish future authenticated sessions, however unless you are in a location where eavesdropping attacks are a risk, there is no need for encryption as the session ID is either a hashed string in a cookie, or the servlet is making use of URL re-writing, both of which are only temporary passes until the HttpSession has been invalidated. Second, to answer the question regarding actions redirect to HTTP... The reason the redirects are not going to HTTPS is because of the RequestDispatcher. When Tomcat sees that you are trying to access a resource for which login is required, it FOWARDs the request to the login form. The security constraints defined in web.xml are for when requests are made directly for those resources. What this means is that your configuration to make sure that the login pages use SSL only come into affect when the browser requests them directly. Requests that have been FORWARDed by the RequestDispatcher totally bypass the SSL constraints. What is the solution? Create a Filter subclass with the sole purpose of having its doFilter method call sendRedirect on the HttpServletResponse object. Map this Filter to the same URL pattern you use for SSL and make sure to use the dispatcher tags for FORWARD, INCLUDE, ERROR, and whatever other RequestDispatcher operations you want to ensure use SSL. Hope this helps.

From a server load perspective having to perform SSL computations for every single HTTP request can be a serious performance bottleneck. Of course - everyone recognizes that. Serious sites will offload the SSL processing to a separate box or NIC card for that very reason. however unless you are in a location where eavesdropping attacks are a risk, Such as pretty much anywhere on the Internet? If eavesdropping attacks were not a risk, there would be no point in encrypting the security credentials.

Re: Tomcat and problems with languages

I've a problem with a web application developped with struts and which uses different languages with properties files (so if the brower's setting is english the application will display texts in english, if it's italian twxts will be italian and so on..) On a tomcat 5.5 on a windows workstation everything goes fine: when you change the browser's language the application's language will change too. The same application on tomcat 5.5.15 on a linux workstation causes some problems: if we restart the server the application will respond with a mix of the browser language (italian) and the default (english) and the only way to make it go well again is to restart again the server. I've no idea at what tomcat setting see and change. what way can I try take to solve this problem? Any hint? Thank you very much.

Dear Leon, i'm performing a jmap -histo:live on a tomcat which froze because of full (8GB) old space gen, and my top 10 looks like: num #instances #bytes class name -- 1: 19268009 2655683368 [C 2: 17410092 1392807360 org.apache.tomcat.util.buf.MessageBytes 3: 17411294 1114322816 org.apache.tomcat.util.buf.ByteChunk 4: 17410562 974991472 org.apache.tomcat.util.buf.CharChunk 5: 19275640 771025600 java.lang.String 6: 8697280 626204160 javax.servlet.http.Cookie 7: 8699584 417580032 org.apache.tomcat.util.http.MimeHeaderField 8: 188 134247456 [Lorg.apache.tomcat.util.http.MimeHeaderField; 9:198645 114493776 [Ljava.lang.Object; 10: 21303 30450504 [B So how did I manage to get almost 9 million of mimeheaderfields and cookies and 17 millions message bytes and chunks. During normal operation mode the number of the above doesn't increase except before the gc freeze. You can try to generate a heap dump and analyse it using jhat. Trouble is, jhat requires insane amounts of memory. So for you 8GB dump you'd need something in the order of 32GB RAM for jhat. If that is feasible, you could lower the memory limits on your machine, run the tests again to get a smaller dump with (hopefully) the same characteristics. -- Kees Jan http://java-monitor.com/forum/ kjkos...@kjkoster.org 06-51838192 The secret of success lies in the stability of the goal. -- Benjamin Disraeli - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
