Re: Urgent : Can we restrict access to a directory in tomcat
The other way to do it would be to check the referer page, this seems to be quite a common trick and will confound most people trying to link directly to your images (which is what I imagine you're trying to prevent). There may be a more elegant way of doing it, but you could create a servlet that is mapped to your /images mount point which inspects the referer field in the request and, assuming it is valid, returns the appropriate content from a directory outside of your web application. As all requests would go through the servlet you have access control. Tom Shapira, Yoav wrote: Howdy, That one's tricky (and strange). When you have a servlet or JSP, the output the user sees is HTML. In HTML, you have img tags. The browser will request those images normally in HTTP requests. So from the server's perspective, the request is the same whether the user types in the image URL or you embed it in one of your pages. Would something like using a mangled images directory name ($KF_%# or something) be sufficient? A name that's hard for users to guess and use directly?

Re: Proper way to deal with serialization of session attribute withLogger attribute
Make the logger static? Effectively the same as you're creating it from the class name anyway, and avoids attempts to serialize it as it's not attached to an object of any kind. Tom Karr, David wrote: I'm using JDK 1.4.1, and Tomcat 4.1.24. I was seeing a strange situation where some cactus/ant tests of mine would succeed on one run, and then fail on the next, and alternate in that pattern continuously. After looking carefully at the Tomcat logs, I discovered that a class that is instantiated and then put into the session has a Log4J Logger object. Tomcat tries to persist that session, but it fails because Logger is not serializable. If I want to allow objects of this class to be serialized and deserialized, how do I deal with the contained Logger object? The class presently defines it's logger instance variable like this: protected final Logger logger = Logger.getLogger(this.getClass()); Do I instead have to make this transient and change all the references to the logger instance variable to call an accessor which tries to initialize the value first if it's null? Or perhaps do I have to add writeObject() and readObject() methods where the writeObject() method specifically writes all the fields but this one, and the readObject() method reads all those fields, and then manually sets the logger value? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: System user accounts required to use manager in 4.1.12?
I find it unlikely that a path like that ever worked on any system. You're sending parameters to a server, so the code that needs to read the .war file is running remotely. There is no way that the remote server will understand your 'C:/path/.../foo.war', it simply doesn't exist there. You need to put the war files onto an HTTP server somewhere, quite possible using IIS or Apache on your win2k machines, have the users copy the war files into their web space and then access them by HTTP from the manager application (i.e. use the http://my.workstation/~me/mywebapp.war rather than a local file path).

Re: Can two tomcats back each other up on one machine?
Brandon Cruz wrote: I am running tomcat 3.2.4 (I know it's old, but it works great!). We typically have around 50 database connections and twice as many sessions going at any given time. I would like to set up another tomcat, or find a solution to restart without having to kill everyone's session. Is there anyway I can set up this up so that if one tomcat goes down for restart the sessions can automatically be transferred over to the other tomcat? After I restart the first, then I can restart the second the same way. The problem is that we usually add two or three virtual hosts per day and need those changes to be recognized. Has anyone done anything like this before or run into the same problem? Not sure about exactly how you do what you're describing, but another solution is as follows. 1) set up a redirector with sticky session management, so requests are routed through to whichever container their session is bound to 2) when you want to update your services, you don't shut down either container, you simply prevent new sessions being created on one or the other. 3) when all active sessions have cleared from the unreachable container, you can shut it down and reconfigure it 4) repeat in the obvious fashion for the other It may be possible (well okay, it's possible, it may be easy) to automate this, and similarly it scales to multiple instances quite nicely. It's trivial if you have good hardware redirectors, but they're not exactly cheap bits of kit so it's entirely likely you don't.

Re: Problem with doPost() method executed twice in parallel
[EMAIL PROTECTED] wrote: And suddenly, whereas the code is executing in an extern method, the traces situed at the begin of doPost() method are displayed a second time !!! It looks like if doPost() method was executed a second time IN PARALLEL of the first doPost() (because the external methods issued from the first doPost() continue to execute). This is correct. The servlet container will create a single instance of the servlet class that you have written, calling the init() method at the time of creation. After this, each request to your servlet will map to a separate thread, all of which run through the same object (your servlet). If you are accessing external objects as part of this process, you must ensure that either your external resources are created per-access, so created and referenced within the doPost() method, or that they are thread safe, as you have no control over when they are accessed. Exactly why you are getting two invocations of your doPost() call is unclear, it depends on what is trying to access it, but this kind of behavior is common and intentional.

Take a look in the catalina.out logfile, it would tell you whether this is happening (you'll get complaints about an invalid web.xml file) To make a file visible to all webapps should just be a question of telling the other webapps where on the file system the xml file is located surely? If you're accessing through HTTP you could set up a dummy context with access restricted to localhost that contains your configuration files.

Re: log analyzer?

You could take a look at awstats, if you have tomcat-4 and set the log format to 'combined' then this works just fine out of the box, otherwise it's sufficiently configurable that you could probably get it to read the tc3 access logs. It's located at http://awstats.sourceforge.net, I'm running it fine on tru64 unix and win32 with activeperl. HTH.

Re: Is this the way to do it?
Järkeborn Joacim wrote: HI Magnus, Make use of the simple datatype 'boolean' instead of the object 'Boolean' or... : boolean BoolDans = (new Boolean(request.getParameter())).booleanValue(); The Boolean class has a String constructor that returns Boolean.TRUE if the string is not null and equal to true and Boolean.FALSE otherwise. The 'booleanValue' creates a primitive type from this. BTW - 'new Boolean(false)' is not all that good an idea, use 'Boolean.valueOf(false)' instead, as this avoids the overheads of object creation etc. Tom Oinn
Re: Destination Port for mod_jk
David Smith wrote: I believe it's the same as a conversation between your web browser and Apache. When Apache makes a request of Tomcat, it uses the first available port on the local machine to open a connection to Tomcat. In a linux box, check /proc/sys/net/ipv4/ip_local_port_range for the range of available ports. Tomcat will reply back on the same port. If you really want firewall security that tight, you might want to check into stateful inspection on the Apache server. There, the ports are opened based on outgoing requests and closed when the connection is closed. I believe iptables supports this using the state match extension module, but you'll have to check the docs since I've never tried it. My thoughts on the subject -- anyone else? Assuming that each machine can reasonably trust the other, you could add a completely isolated network interface to each machine, and set up the apache and tomcat to use this interface, effectively you have no security constraints on the interfaces between the two servers and all your firewalling goes on on the machines' primary interfaces to the rest of the world. We have a similar system with tomcat / oracle machines and it seems simple and secure enough.

I am using ajp13 to connect the two machines, and am trying to configure an iptables firewall on the apache machine (the tomcat machine will be next). The roadblock that I'm running into is that I don't know which ports will be used as the destination ports on the apache machine when tomcat replies. The ports that I set up in server.xml and in workers.properties are the source of my replies... Looking at my syslog log file, I see that I'm getting information sent to ports 32769 up through 32792 (and maybe even more, I haven't looked through them that much yet).

Or, does anyone know which ports I need to be leaving open? Thanks very much for any help! Sincerely, Scott

Recently, I was looking for a good admin tool for MySQL. All I found was MyAdmin, which is written in PHP. I don't want any PHP on my server, so I decided to write my own software, and here it is - the first version of OurSQL. What it can do? Right now - you can log in to any MySQL database (local or remote) and execute any queries you want, viewing results. The goal is, of course, to make easy any frequent operation. Tell me what do you think, any suggestions, etc. Yes I know the current version sucks. Think of it as an interactive demo.
