how to enable Tomcat to handle proprietary TCP streams (non-http data)
Hi I'm writing application composed from few loosely coupled components (dependency injection pattern, all compoments written by my team). First of them listens for connections, spawns new thread (serversocket.accept) receives data in proprietary format and then sends data to next component, next component transforms data (optimizes, creates some packages), and next component sends data further (probably using WebServices or WebDAV). Additionally I need to track/monitor whole application/process by external application placed on user computer (connected thru WebServices) I want to put this whole application on Tomcat. It would perfect if tomcat can accept connection (serversocket.accept), spawn new thread (my my code) and pass socket (input/output streams) to it. then my components can handle whole business logic (maybe with Spring help). How to enable Tomcat to receive propertiary TCP stream (i have external library for this), GenericServlet is for http data and I need something for non-http streams. I've searched for solution and found http://www.mail-archive.com/users@tomcat.apache.org/msg12810.html http://marc.info/?l=tomcat-userm=122193433217430w=2 http://marc.info/?l=tomcat-userm=119569480213083w=2 http://marc.info/?l=tomcat-userm=117289842121590w=2 Is this a good place to start?

Separte http connector for 2 apps.
Hi Experts, I have 2 applications call it app1 and app2 deployed on the same tomcat server (6.0.18). The external client use both of these apps. Right now both the apps use same http connector on port 8080. So threads and corresponding thread setting (like maxThreads, acceptCounts etc) associated with connectors are shared between the 2 apps. That means if the traffic increase for app1 and request for it start to queue up, the app 2 request may suffer delay or time out. Going through the documentation, it seems one way of resolving this would be, to declare 2 separate services in service.xml for the 2 apps. Each service will have its on http connector with appropriate maxThread and acceptCount settings. That way high volume on app1 does not starve or timeout the app2 requests. Also we are thinking of restrict maxthread and accept count on app1 to low value, so that it does not hog processing resources etc. Some other reason we cannot put these apps on different tomcat instance. This would ideal solutions but not possible in this case. Please suggest if there is other or better way of doing it. Thanks in advance Shri.
Re: HTTP status 404
webapp -- filename -- WEB-INF-- filename.htm + web.xml + META-INF + classes + lib If I read this right, 'filename.htm' is being stored in webapp/filename/WEB-INF/filename.htm inside your .war file. FWIW, WEB-INF has no special meaning except in the top level of your .war archive A .war archive built like this will most likely deploy as a static html folder and everything in it will be available as static files. HTTP status 404 description the requested resource (/filename/)is not available If you wanted to get filename.htm with the structure I think you are describing, you should be requesting /$WEBAPP/webapp/filename/WEB-INF/filename.htm where $WEBAPP is the context your war file is deployed under. Usually $WEBAPP is the name of the war file. For instance if the .war file is myapp.war, the request path to filename.htm under tomcat would most likely be myapp/webapp/filename/WEB-INF/filename.htm To fix a *lot* of problems right off the bat, your war archive should look more like: filename.htm WEB-INF web.xml classes lib META-INF (what ever lives under here) Then the request path (again assuming the war file is named myapp.war) would be /myapp/filename.htm --David On 12/8/2010 2:39 PM, Lava Saleem wrote: Hi everyone, I have a single page html file with java script embadded in it, I have created a war file for it and deployed it successfully but when I click on the page I get the below error, the structure of my war file is the following webapp -- filename -- WEB-INF-- filename.htm + web.xml + META-INF + classes + lib I did not modify the web.xml since I don't need the servlets do I need to modify anything?

If you want to make a war file, then go to the parent directory and issue the following command from the command line: jar tf Static.war Static Please note that case is important.

HTTP status 404 description the requested resource (/filename/)is not available Hi. Except the 404 error which your are getting, not much above makes any sense at all. So it is better to forget all that, and start new. You really have to learn to walk before you can run. First, consider the directory structure of a standard Tomcat installation : (CATALINA_HOME) (=CATALINA_BASE) | |- bin (tomcat programs and scripts) |- conf (configuration files) |- lib (global library files) |- logs (logfiles) |- webapps (* web applications *) |- ROOT (the special, top-level, default web application) |- app1 (a web application) |- app2 (another web application) |- ... |- lastapp (another web application) In the above, (CATALINA_HOME) represents the top directory of your Tomcat installation, the one under which the rest of Tomcat is found. For example, on your system it may be C:\tomcat or C:\program files\Apache Software Foundation\tomcat6.0 or /usr/share/tomcat6 or /usr/local/tomcat6 or whatever. The webapps sub-directory is what is important for you now. That is where you will put web applications, composed of static html pages (with or without javascript in them), JSP pages (special html pages with embedded Java code), java servlets (compiled java applications), etc.. The ROOT web application is special. It is the default application. When you use a URL like : http://yourserver.yourcompany.com/abc.html Tomcat is going to look for abc.html under the webapps/ROOT directory. The other subdirectories under webapps are each one separate web application. To access for example the application named app1, you will have to use a URL starting with http://yourserver.yourcompany.com/app1/; For example, if you place a html page named xyz.html in the subdirectory (CATALINA_HOME)/webapps/app1, then the URL to call it up will be http://yourserver.yourcompany.com/app1/xyz.html Under such a web application directory like ../webapps/app1, there is also a structure. It looks like this : (CATALINA_HOME) (=CATALINA_BASE) |- webapps (* dir, top of all web applications *) | |- app1 (dir, contains the web application named app1) - public files (html etc..) - WEB-INF (directory) |- files (private) |- web.xml (configuration file for the application) |- classes (dir.) |- compiled java classes, like servlets |- lib (dir) |- java libraries for this webapp - META-INF (dir.) |- context.xml (more settings for the application) Basically everything under app1 is optional. Tomcat will supply a default if needed. Of course, you will want at least one file under there, to make the execise meaningful. What is in the sub-directories WEB-INF and META-INF, can never be obtained directly by a browser. Tomcat will not allow it. So if you enter the following URL in the browser : http://yourserver.yourcompany.com/app1/WEB-INF/something Tomcat will respond with an error, even if something exists. But to start, I suggest that you just - stop tomcat - create a new sub-directory under ../webapps/, for example myapp. - under that subdirectory, place a file called myfile.html - verify that the ownership and permissions of these files are such that the Tomcat user can read them - start Tomcat - in the browser, enter the URL : http://yourserver.yourcompany.com/myapp/myfile.html and enjoy. Now play around with the above : - create another page mypage2.html, place it alongside myfile.html, start Tomcat and call up the new page in the browser. - then stop Tomcat again, and create another subdirectory under webapps, put something there, start Tomcat and call it up with the browser. - then stop Tomcat again, create a sub-directory WEB-INF under one of your webapps, put something in it, start Tomcat and try to call up that file. When you understand exactly how that works, then go read this page (again) : http://tomcat.apache.org/tomcat-6.0-doc/appdev/deployment.html And then you should come back for more questions about how to make .war files and deploy them properly. (tip : a .war file is just a zip file with the same content as the app1 subdirectory above. It has to be named app1.war, and you have to copy it under /webapps/ for Tomcat to understand what you want).

Q: what about a simple front-end proxy, which would take care of the HTTPS part for the externals, and connect internally to Tomcat over standard HTTP ? The internals can go around the proxy and access the application directly via HTTP. A minimal Apache httpd, running on the same box, would do that easily. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Going through the documentation, it seems one way of resolving this would be, to declare 2 separate services in service.xml for the 2 apps. Correct: Connectors are associated with a Service, a Service has multiple Hosts and each host has any number of deployed webapps. In order to have connectors serve separate webapps exclusively, you actually have two options: 1. Two Services, separate Hosts, Connectors, and deployed webapps 2. Single Service, Host, and webapp with two Connectors: each connector must be on a different IP/port combination so you can have users of one webapp use a specific connector. You can enforce the use of a specific Connector by using a Valve or Filter to check the incoming port number and rejecting requests for the wrong webapp. Each service will have its on http connector with appropriate maxThread and acceptCount settings. That way high volume on app1 does not starve or timeout the app2 requests. If you have other shared resources such as a database, you might still have one webapp affecting the other.

Re: enforcing SSL only for external clients
Aggarwal, Ajay wrote: Most of the application will be over SSL for external clients. There is one part where the clients may upload or download a huge file over HTTP which I don't want to go through SSL. I am thinking uploading/downloading these huge files over SSL will create lot of stress on the server. Let me be constructively critical and provide my 2 cent : If we are talking about a standard web application using a standard html interface and standard browsers, then such an upload would be triggered by a POST from a html form with a input type=file in it, right ? If the upload URL (target of the form) is not within the HTTPS protected part, then anyone could access it and post a huge file to your site, no ? That may cause more stress on your server than doing this via HTTPS ever would. Or else, how are you going to ensure that any client uploading a huge file to your server is entitled to do so ? Plus, you may need to know who is doing this, just to know what to do with the file. So you would need a form of authentication that starts under HTTPS, but is valid also when posting the form under HTTP. Not necessarily evident, and in any case not evident with any of the standard Tomcat authentication methods, as Christopher pointed out. Note that there can be ways to achieve a reasonable level of security for doing this kind of thing (reasonable being a flexible concept dependent upon your precise context). But running most of the site under HTTPS except for that upload portion seems leaky to me. Better and cheaper maybe to get a bigger server. You run the risk otherwise to spend more than the difference, trying to find out ways to do this securely, which is what HTTPS provides as a matter of fact. I would run a test, uploading the same file over HTTP and over HTTPS, and measure the system's reaction, to determine really what overhead this causes, percentage-wise, for the server. Decryption should be 99.9% CPU, and in my experience that is a facet where modern servers are rarely overloaded. With huge files, your communication bandwidth is more lilely to be the limiting factor. And if it really overloads the server, then again the solution may be with a front-end which takes care of the HTTPS part. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Naive suggestion : how about some global flag which the legitimate shutdown paths set (and the others don't know about), and which the hook in question checks ? Other naive suggestion/question : something somewhere already intercepts a System.exit(), if i judge by the shutdown messages of the Connectors. How about making the flag a code or string, which would indicate which legitimate agent triggered it, and which the things which print the Connector shutdown messages obtain and duly add to their shutdown message ? The absence of ditto (or the initialisation content of it) would be a telltale sign. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
deploy log4j
Hello
I have an app that work perfectly in my IDE(JBuilder05, yes I know but it work
fine), but on deployment I believe it is not reading the log4j with this error:
java.lang.NullPointerException
at java.util.Properties$LineReader.readLine(Unknown Source)
followed by
log4j:WARN No appenders could be found for logger
I am loading the prop file with this(that works in the IDE)
java.util.Properties props = new java.util.Properties();
try {
props.load(getClass().getResourceAsStream(/log4j.properties));
}
catch (IOException ex) {
}
PropertyConfigurator.configure(props);
//ver03_lfj.setLevel(Level.DEBUG);
ver03_lfj.debug(yippie);
Re: deploy log4j
You don't say the following:
Tomcat version
JRE/JDK version
Platform (OS and version)
That being said, I use log4j (with or without Apache commons logging) for
nearly
every web application I run on Tomcat.
Short answer: You don't manually read in your properties file with log4j.
Read a tutorial on log4j for a more complete explanation.
What follows below is an overview. Please refer to the log4j documentation, the
log4j javadocs, and tutorials around the Internet for a more complete
discussion.
Code:
In each class that you want to use logging, add the following:
package foo; // replace with your package name
import org.apache.log4j.Logger;
public class MyFoo { // replace with your class name
private static final Logger log = Logger.getLogger(MyFoo.class); // note 1
/*
* rest of class including log.(message) where is a level
*/
}
note 1: While it is traditional that one uses getLogger(MyFoo.class), which is
shorthand for getLogger(clazz.getName()), you can also name your loggers with
any legal string. See the javadoc for more information.
Properties File:
In your properties file, you'll need appenders as well individual lines for
non-default logging levels for each logger name.
### direct messages to file foo.log ###
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=${catalina.home}/logs/foo.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# default logging level
log4j.rootLogger=warn, file
# logging for foo.MyFoo - name matches the logger name
log4j.logger.foo.MyFoo.type=info
Since there is only a file listed in the appenders, then that's where the
logging will go.
Note that ${catalina.home} was used for logging. This should probably
be ${catalina.base} just in case more than one copy of Tomcat is run from a
base
installation (see RUNNING.txt). This is a handy way of storing log files.
If you're doing some in-IDE testing where ${catalina.home} or ${catalina.base}
is not set, then hopefully your IDE will let you pass in a Java parameter. Just
set
-Dcatalina.home=some-place (or -Dcatalina.base=some-place) while testing.
Application Structure:
Properties file
Package up the application so that log4j.properties gets placed in
WEB-INF/classes/log4j.properties. Log4j looks for the properties file in the
classpath. Placement in your IDE's project depends on how your IDE packages
files.
Log4j library
Package up the application so that log4j-1.2.15.jar (or whatever version you
are
using) gets placed in WEB-INF/lib/log4j-1.2.15.jar. Placement in your IDE's
project depends on how your IDE packages files.
. . . . just my two cents.

uniqueId of StaticMember
Hello, What exactly the uniqueId of StaticMember class? How is it being used in implementation? Can multiple static nodes have same uniqueId? Any pointers? Thanks,

There is no trivial easy way to perform this trivial function. The defaultServlet is great for the utterly trivial but if you want anything marginally more sophisticated then it is no longer a simple case of droping in your content.
