I've been trying to get the JavaWorld example located at http://www.javaworld.com/javaworld/jw-03-2005/jw-0307-captcha.html On tomcat v5.5.9 (JDK 1.5) on Linux without any luck. It goes through the authentication process and reports it's assigned the anonymous principle but when I go to access the protected directory again it prompts for the login.jsp page again. Any ideas guys Thanks Ron - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Retry, problems using j2ee JMS in Tomcat 4.x.x
Hi all,
Using win2k, JDK1.3.1, J2ee1.3.1.
I have created a small JMS system to generate pdf files. I created a very
short test servlet.
In tomcat 3.2.3 my queue is found. In tomcat 4.0.4 and 4.1.12 I get the next
error:
NamingException
javax.naming.NameNotFoundException: Name QueueConnectionFactory is not bound
in
this Context
at org.apache.naming.NamingContext.lookup(NamingContext.java:811)
at org.apache.naming.NamingContext.lookup(NamingContext.java:181)

at org.apache.naming.SelectorContext.lookup(SelectorContext.java:183)
at javax.naming.InitialContext.lookup(InitialContext.java:350)
My code is :
protected void handle(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException {
try {
// Create the initial context
Context ctx = new InitialContext();
Hashtable env = ctx.getEnvironment();
Enumeration enum = env.keys();
while (enum.hasMoreElements()) {
String key = (String) enum.nextElement();
System.out.println(key + = + env.get(key));
}
QueueConnectionFactory queueConnectionFactory = null;
Queue queue = null;
try {
// The next definition works in tomcat 3.2.3
queueConnectionFactory = (QueueConnectionFactory)
ctx.lookup(QueueConnectionFactory);
queue = (Queue) ctx.lookup(generatePDF);
// The next definition doesnt work in either tomcat
//queueConnectionFactory = (QueueConnectionFactory)
ctx.lookup(java:comp/env/QueueConnectionFactory);
//queue = (Queue) ctx.lookup(java:comp/env/generatePDF);
System.out.println(Found the queue generatePDF);
}
catch (NamingException e) {
System.out.println(NamingException);
e.printStackTrace();
}
// Close the context when we're done
ctx.close();
}
catch (NamingException e) {
System.err.println(Problem + e);
}
}
And here is my JmsDestination and JmsFactory listing:
D:\jakarta-tomcat-4.0.4\binj2eeadmin -listJmsDestination
JmsDestination
--
JMS Destination : sendPDF , javax.jms.Queue
JMS Destination : jms/Topic , javax.jms.Topic
JMS Destination : jms/Queue , javax.jms.Queue
JMS Destination : generatePDF , javax.jms.Queue

JMS Cnx Factory : TopicConnectionFactory , Topic , No properties
JMS Cnx Factory : jms/QueueConnectionFactory , Queue , No properties
D:\jakarta-tomcat-4.0.4\bin
After running the servlet on 3.2.3 I get 2 errors for loading ejb and
security.properties file, but after that it prints the following for the
enumeration
on the context:
java.naming.corba.orb = com.sun.enterprise.iiop.POAEJBORBa49e0
and for tomcat 4.0.4
java.naming.factory.initial = org.apache.naming.java.javaURLContextFactory
java.naming.factory.url.pkgs = org.apache.naming:com.sun.enterprise.naming
So here is a big difference. The one from 3.2.3 appears to be an instance of
a class
whereas the ones from 4.0.4 are just string representations of classes to
load.
Now how can I activate my Jms system, in order for Tomcat 4.0.4 to find it?
Or what should I do so Tomcat will be able to find my queues and use them?
Re: Retry, problems using j2ee JMS in Tomcat 4.x.x
Thanks for your answer Jean-Francois.
The QueueConnectionFactory indeed isnt defined in my web.xml environment
tags. I will see if I can find a good j2ee list to help me get along on the
road, but thx for tips

Ronald

OK I will give a try. I think you have to define your
QueueConnectionFactory
in your web.xml file in order. Is it the case? Look at the Servlet Spec
for more info:
http://jcp.org/aboutJava/communityprocess/first/jsr154/
Specifically in the DTD section. Also, maybe a j2ee related list might be
the place to have a faster answer ;-)

Asynchronous messages from servlets
Hi, I have the following problem. A simple form submits data to a servlet. The servlet sends a message via JMS to another application (in another JVM). Once the message has been sent, the 'service' method of the servlet ends. After a while, say five seconds, the other application would like to send back a response. How do I show this response to the user? Since the 'service' method has finished after sending the message, I have lost control over the output from the other application. What I need is a way to push the response to the browser. I would like the server to take the initiative in updating the browser window, not the user. Is this possible in any way?

Re: Problem running Tomcat 4.0.4 under JDK 1.4.1
Hello, I've seen the same problem by a colleague. He installed JDK 1.4 next to JDK 1.3 and mixed the standard classpaths of both JDK's. JDK 1.4 uses a new class-file format. JDK 1.4 is backwards compatible, but you must use its own standard classes. So, make sure your old JDK is completely uninstalled. Or rename the directory of the old JDK, so the system doesn't find the classes/programms anymore. Greetings, Ronald.

Re: Problem running Tomcat 4.0.4 under JDK 1.4.1
I can tell you I've Tomcat 4.0.4 and JDK 1.4.1 running. So it does work. And I also use a lot of third-party packages compiled under previous JDK's, so that's not a problem. Just don't mix the base classes and make sure you don't run JDK 1.3 with the JDK 1.4 classes accidently. Windows is a bit non-transparent in where it defines it path's and stuff, so I'm always unsure which application is run. My experience is that the path can be different in a dos-box and from windows self. Ronald. Donie Kelly wrote: I'm doing a good cleanout at the moment.

void doGet(request, response) {
...
// Get request info
...
out = response.getOutputStream();
out.write(htmlbodyHello, everything is ok./body/html);
out.close();
...
// Do the transaction here
...
}
Greetings,
Ronald.

Hi all
I want to run a long transaction which lasts about 2 seconds with tomcat but
after I have gathered the information from the request I want to return 200
OK to user and close the connection to the browser. However, the thread
should continue to process the request and when finished it should return to
the thread pool tomcat has.
I want to set the tomcat pool up as follows in server.xml
Connector className=org.apache.catalina.connector.http.HttpConnector
port=80 minProcessors=5 maxProcessors=5
enableLookups=true redirectPort=443 acceptCount=100
debug=0 connectionTimeout=6/
So basically, I want only 5 threads running at any time and under load
conditions it should cause a backlog of 100 with 5 threads doing the
processing. It is important though that the threads return quickly to the
user.
Thanks for any solutions
Donie

can't display jsp compile errors when using error-page.
Hello, If I use error-page in web.xml, jsp compile and runtime errors are going to the error handler. If you use errorPage='error.jsp' only runtime errors are handled by my error page.

If Jasper throws an JasperException, because of a JSP compile error it is also handled by this page, but there is no exception in the error.jsp page. Because it is probably handled as a '500 Interal Server Error'. How can I get the error/exception of this in my error.jsp?

See javax.servlet.ServletContextListener. A context is destroyed and initialized when Tomcat is reloaded. You can define a context listener in WEB-INF/web.xml: listener listener-classbla.bla.MyContextListener/listener-class /listener Works very well for my applications.

gzip compression in Coyote on 4.1.24
Hello, Sorry if this is send twice, but I think my previous mail got lost in cyberspace somewhere. (Can't even find it in my Sent-box.) I'm trying to use gzip compression with tomcat 4.1.24. And it doesn't work, because it checks if content-type is 'text/html', but this fails if the content-type is 'text/html; charset=us-ascii'. So compression='force' is the only way to use compression, but this also compresses image/gif, etc. Does anybody else use this? I made a bugreport with a (possible) fix. See bug 18073 (made by myself) and 2820 [1]. Greetings, Ronald.

tag and method overloading
Hello,
Is it possible to overload a method of a tag.
In JSP:
String arg1 = bla;
int arg2 = 5;
mytag name=%= arg1 % /
mytag name=%= arg2 % /
In the class:
public void setName(String s) {
...
}
public void setName(int i) {
...
}
I get errors like: can't find setter method for String.
Is this supported? If yes, are their known pitfalls?
Any pointers to docs about this? Already tried google, but didn't find
anything relevant.

Ronald.

The easiest way would be not to call close() on the response's output stream. Is there a reason you need to call close()? The servlet spec says that sendRedirect has the side effect of committing the response and terminating it.

at all.

RE: Tomcat Realm Authentication + Storing Objects In The Session
My biggest unknown right now is, because the server handles the creation of the session, what would it take to make the server grab a user object from the database and store it in the session after the user logs in? Can't you use an HttpSessionListener for this? It is called right after a session is created (and when it's destroyed again). I'm not sure though whether there's enough information in the HttpSession object for you to be able to grab something from the database at the time HttpSessionListener.sessionCreated() is called.

RE: redirect and request´s attributes doubts
Hello dudes, i´m trying to set some attributes to a request in my servlet, that´s pretty easy as you know, but after i must use redirect to a JSP page and when i try to recall those attributes created before they doesn´t appear in JSP´s request object. Even thought i set a request´s attribute and use redirect i cannot get it again, can i? The attributes you add to the request are added on the server. There is a request object on the server that you add attributes to. If you use sendRedirect, the client (browser) receives a redirect response from the server (status code 3xx), with the location to redirect to. The client then creates a _new_ request for the new url and sends it to the server. The server creates a new HttpServletRequest object for you that has nothing to do with the old object.

Dear folks, How could i dump HTTP Response and Request headers. Im using Apache 1.3 and Tomcat 4.0 MOD_JK.

RE: Setting page content Type
I have been experiementing with jsp:directive.page contentType=... / @ page contentType=... / but none of them seem to be able to take a variable value for contentType, These constructs will indeed not work (and they never will work in future versions either). The constructs you use are directives (the first one in XML syntax, the second in JSP syntax). Directives are interpreted at page translation time. The tags you attempt to use are not executed at page translation time but at page execution time (when a request is received for the page). Directives can not have variables as attributes, since the value of these variables can never be known at the time the page is translated to a servlet.

RE: Passing init params to a listener?
G'day, I assume from this that init parameters can only be accessed by a listener if they have been declared globally within the applications context and not from within the scope of the listener itself? Hm You can not specify initialization parameters for individual listeners. The syntax you use is even illegal. I do not really see why this should not be possible, since all other web components (servlets, filters) can be parameterized, but that may be something for a future specification.

RE: Filters and load-on-startup
Hi, Do filters get loaded before servlets regardless of load-on-startup value? I don't think so: as filters can be mapped to servlet-name, servlets must be loaded first. (Although I suppose you could read web.xml, so you have the servlet info, then instantiance filters, then instantiate servlets, but tomcat doesn't do this). I wouldn't rely on this order unless you had to, however, as it's not mandated either way by the Servlet Specification. Actually, it is. SRV9.12 mandates the following load order: listeners, filters, servlets (Servlet Specification 2.4). So any filters should be loaded before any servlets, regardless of load-on-startup value.

RE: caching static objects
We are running Tomcat-standalone and are having some caching issues. It appears to be a browser issue, but there's got to be some workaround. We've got the headers set to pragma nocache, but it continues to cache objects, such as charts that are created dynamically. I suppose this wouldn't be an issue if the code worked with Apache. Also, creating unique identifiers for each object has been shot down. Does anyone know of a way to get server.xml to set each object not to cache? Thanks. The 'Pragma' header you use is from HTTP/1.0. Most caches, including browser cache, by now use HTTP/1.1, where cache control is achieved differently. You should use 'Cache-Control' headers (although it never hurts to also use 'Pragma' headers, in case you encounter an older HTTP/1.0 cache). For more information you can look at the HTTP/1.1 RFC at: ftp://ftp.isi.edu/in-notes/rfc2616.txt and search for the text 'Cache-Control'.

upload file with non-ascii characters in name

When I run Tomcat on Windows and upload (with IE)a file with non-ascii characters in the filename it goes well.But when I run Tomcat on Linux and do the same upload it doesn't recognize the non-ascii characters and prints them as squares or question mark.

Re: Tomcat for FreeBSD
If you have installed the FreeBSD ports collection (which you probably have), than do this: cd /usr/ports/www/jakarta-tomcat5 make make install make clean The 'make' command wil show some settings, which may be readable depending on how fast your computer scrolls text.

bug in JDBCStore in 4.1.27
Hello, Is anybody interested to fix BUG# 19034 (InvalidClassException in StoreBase.java)? http://nagoya.apache.org/bugzilla/show_bug.cgi?id=19034 It is still in there and generates a lot of errors if I update my web-application.

mail.jar and activation.jar in Tomcat 4.1.29
Hello, Why is mail.jar and activation.jar added in Tomcat 4.1.29 in common/lib? My webapp uses it's own mail.jar (1.3.1 in stead of 1.2) and activation.jar and everything doesn't work anymore. I think this is a major 'API' change for a minor release. For what are these api's used by Tomcat? I can't think of anything that a webserver does with mail. Greetings, Ronald.
RE: mail.jar and activation.jar in Tomcat 4.1.29
I have made handlers for multipart/related, etc. for use in a web based mailclient. This gives a lot of trouble with ClassLoaders. Removing mail.jar and activation.jar from common/lib solves the problem. And I'm 100% sure, that I've never had to do that before 4.1.29. Greetings, Ronald.

Re: RE:how to set encoding parameter in Tomcat4...
I set request.setCharacterEncoding(...) before handling the request. My Tomcat-5 doesn't pick up the content-type of the request from a browser, because browsers do not send content encoding as http headers. Maybe xmlRPC does the same. I recommend you to use a network sniffer for looking what bytes are really send over the wire between the application and the server and tomcat and the database.

Yes, I understand that, but I was wondering if there is more experience with using a cluster under load. I am thinking about timeout settings? Or maybe something else.

Re: Running lots of virtual hosts on tomcat
RJ, I think with a filter we can do our own version of mod_vhost. But for reloading the classes/jsps it needs two instances of Tomcat (maybe on the same machine) with a loadbalancer to update one without interrupting the user. Or is the compiler build into Tomcat 5.5 fast enough (and without memory leaks enough) to run it on a production machine. Ronald.

Re: maxPostSize and file upload
After rereading the docs I understand that the maxPostSize if for FORM URL parameter passing. I think they mean the parameters in the form key1=val2key2=val2... So it is not for file upload I think, only for regular posts. Unfortunately I don't have time to look in the source, but if somebody knows about this maybe the docs can be updated to be more verbose about this. Ronald.

Additionally, I have no ajp.html file in my Tomcat-5.0.16 distribution, that's strange, 'cause online site has it. Try to set maxPostSize to 2Mb explicitlyto see if it will work. It was a long time ago when I read one article on PHP file upload where it was said that you can't determine a size of uploading data before it at least reaches defined limit, furthermore an error only arised when upload is finished regardless of its actual size (will it be 100Mb or even 100Gb).

Anybody using compressableMimeTypes?
Hello, I'm using the Connector options compression=on and compressableMimeTypes=text/html,text/xml,text/plain,text/javascript,text/css. But it looks like Tomcat is just using its defaults for compressableMimeTypes. Does anybody experience the same thing? I filed a bugreport on this earlier this week, but am looking for more info. I'm using Tomcat 5.0.25 in a standalone environment (no apache in front of it). Greetings, Ronald.
Re: Wildcard virtual hosts help
You can use a default host if I remember correct. All hosts which don't have there own mapping will be handled by the default host. Ronald.

Re: Changing session-cookie(JSESSIONID) name in tomat

I mean can we have a different cookie name to store sessionid? If yes how I can configure it in tomcat. I have two applications running on different tomcats in the same physical box.

At any time there should be only one user logged in with the same user name. Though both these use the same mechanism they are 2 independent application but for some weird reasons should run on the same box. Now we understand that the problem is with the cookie-name JSESSIONID. Since both the applications are having the same cookie name(JSESSIONID) if one user logs on into app1 and an other one is logged on to app2(diff tomcat) with the same username the earlier one is kicked out. We are facing this problem only when 2 tomcats are running on the same box. When they are running on different boxes it works fine but we have to run them on the same box for other reasons. Can someone please point me to a different solution (if available) in case JSESSIONID cannot be changed? Any help is greatly appreciated. Thanks, Dinesh.

Re: AW: ThreadPool: Pool exhausted with 100 threads
Hi Matt,
Another option is this. If you do 'kill -QUIT process-id' on Linux or ctrl-break on
Windows in the dosbox running Java (if this is how you run Tomcat) it will print all
stacktraces of all threads. Very helpfull to track down lost Threads.
And another 'trick' I use is the following filter.
doFilter(request, response, chain) {
Thread currThr = Thread.currentThread();
String oldName = currThr.getName();
try {
currThr.setName(request.getRequestURI());
chain.doFilter(request, response);
} finally {
currThr.setName(oldName);
}
}
The jsp with the threadlist than displays the URL's which are being processed. Very
helpfull. But as far as I now Tomcat 3 doesn't support filters.
Greetings,
Ronald.

As I monitor our systems the number of threads slowly

instead they seem to hang out until the 100 mark is

In effort to avoid this, it looks like we'll be

Regards, Steffen X-Forwarded-For contains the IP address of the client, so Tomcat can return that in ServletRequest.getRemoteAddr() in stead of the IP of the proxy server. I understand this is a security risk if you didn't close your firewall. It is possible to add an option trustProxy=true|false to the config. X-Forwarded-Host and X-Forwarded-Server contain the server name from the request. This can override the setting proxyName.

5.0.19 docs about new clustering config?
Hello, Are there (up-to-date) docs about the new clustering config in 5.0.19? Some attributes are not in the example config (like 'name') and the documents arn't very clear if it's still needed or not. Greetings, Ronald.
Re: Do servlet threads ever die?
On Tue Mar 02 04:02:30 CET 2004 Christopher Schultz [EMAIL PROTECTED] wrote: Ken, Problem: I call native code (Tcl) from my servlet. Tcl's thread model forces me to run Tcl only on the thread that created the Tcl interpreter. So now how do I cleanup these interpreters? The cleanup code needs to be run on the creating thread. Guh. I highly recommend against running native code from an app server. There are lots of reasons I could enumerate if you ask. Number one reason: crashed native code = crashed server. :( Is there a way you can call the Tcl code through a socket or by invoking another process and communicating with it via stdin/stdout? (see java.lang.Process) Do servlet threads ever die besides during shutdown? If not, I may have no problem. AFAIK, Tomcat never retires threads unless something horrible happens (or tomcat is shutting down). Can I register a listener to be invoked on the thread before it shuts down? I don't think you can do this to a thread. You might be able to hack Tomcat's thread pool so that you can cleanup after a thread if it's going to be retired. I don't have any good ideas. Sorry I couldn't help more. -chris Hello, I use a webstart app with JINI for these things. Very easy. I can start a server on any host by webstart and it automaticly connects to the webserver by JINI. You can also create a Thread of your own in the Tomcat server, which you control yourself, but indeed. If you native code crashes, your server crashes. Ronald.

There is a June 2002 mail thread that discusses "How to list all Threads in the JVM?".

Fatal: Stack size too small. Use 'java -Xss' to increase default stack size.
Hello, My Tomcat logs this in catalina.out. Fatal: Stack size too small. Use 'java -Xss' to increase default stack size. I don't see a stack trace, so I can't figure out what is really going wrong here. My current setup is jdk 1.4.2_08 on linux 2.6.x with Tomcat 5.0.28. We are using these parameters to start Java/Tomcat: -Xmx1024m -Xms1024m -Djava.awt.headless=true -Dsun.net.inetaddr.ttl=60. Tomcat is clustered with 3 nodes. Is this a known problem for anybody? Does increasing -Xss solve the problem or does it only make it happen less often? We are running a heavy webapp with 2500 users logged in for 8 hours a day (so sessions live long). Ronald.
Re: Can a client recapture a session in Tomcat 4.1
Yes. You only have to sent the right cookie header to the server. And if the browser exits the right header info is lost. So, if you create a browser which doesn't loose cookie info, you are done. This has nothing to do with which server you are running. For php, asp or anything else it works the same. Ronald.

Would this be a browser-specific thing? After all, I guess I'd need to tell the browser to persist the session cookie or some such thing. Or would it work browser-independently using URL-rewriting? If there is such a mechanism, does it pose any security concerns (e. g. through Tomcat reusing a session-id for a totally different session?) We're on Tomcat 4.1. Would the answer be any different for Tomcat 5.0?

Re: Urgent: how to detect client has closed connection
What Writer are you using? If you do response.getWriter() you will get a PrintWriter and the docs tell you that PrintWriter doesn't throw exceptions, so your app keeps printing to the writer after an error. (A closed connection is an IOException.) If you use the default out property of a jsp page you get a JspWriter which does throw exeptions on error. Ronald.
