Re: where is a text/html;charset= ?
You need to submit a valid HTTP request. Yours doesn't have the version at the end of the request line. Try: GET / HTTP/1.0 (Thats a two linefeeds: one marking the end of the request line and one blank line indiating the end of the http headers) You should then see the HTTP response, headers and all. If you want to submit HTTP/1.1 requests you need to submit some mandatory headers (Host and maybe Date) otherwise you get a 400 back. $ telnet telnet> open localhost 8080 Trying 127.0.0.1...

Re: SessionListener invoked sometimes and not others
And possibly a HttpSessionActivationListener object as a session attibute. The sessionDidActivate() method on the object gets called if the session is still valid when tomcat restarts.

Re: precompiling JSPs -- how to resolve references normally resolved by apache?
Unless you have a directory ${TOP}/web/html/jsp/jsp your uribase/uriroot
probably aren't right.

Hi,
I am trying to get our JSPs to be precompiled as part of
our ant build process to catch all syntax errors at compile
time.
The problem I have run into is that we are using apache +
tomcat and we have set the following rules in apache httpd.
conf:
JkMount /servlets/* ajp13
JkMount /jsp/* ajp13
JkMount /controller/* cont
JkMount /cgi-bin/java-rmi.cgi ajp13
Inside some of our servlets and JSPs, they refer to other
jsps using the absolute URL "/jsp/" which works in deployed
environment because apache redirects it. For example, in
one JSP we have <%@ include file="/jsp/Header.jsp" %>
I setup the tomcat-4.1.30 ant jspc task and it was giving a
NPE. Then I tried the Ant Jspc optional task, and it gave
me an error message:
the file '\Status.jsp' generated the following general
exceptionn: org.apache.jasper.JasperExeption:
/Status.jsp(3,0) File "/jsp/Header.jsp" not found
Is there any quick and dirty way to get the JspC to resolve
the "/jsp/*.jsp" urls to "*.jsp" or is there no way?
My alternative is to try to change all the "/jsp/*.jsp"
references to "*.jsp" everywhere we do an <%@ include %> or
or . I think that would be ok
since those directices are handled on the tomcat side. Changing
it would be kind of messy since we have a ton of JSPs in a
large directory hierarchy, so some of those "/jsp/Header.jsp"
references would have to be changed to "../../Header.jsp", etc.
I know I can't get away from the "/jsp" mapping completely
because we have URLs and HTTP redirects which depend on it.
Here is the quick and dirty jspc ant target I created:

Re: FAQ? shutdown.bat not killing java process on Windows
Yep. It's a FAQ, but not in the FAQ. Tomcat not quitting generally means your webapp has started a non-daemon thread which does not exit when the webapp is destroyed. If so, shut them down in a ServletContextListener. If you aren't explicitly creating threads in your webapp then the usual culprits are database connections that haven't been closed (or any other client api to remote services that uses asynchronous messaging and/or keepalive semantics). To see a dump of the threads still active after you've run shutdown.bat do a CTRL-BREAK in the tomcat dos console. HTH, Jon Charles Fineman wrote: I started Tomcat using startup.bat. Everything goes fine. I use shutdown.batto bring it down. The server fields the request and shuts down a bunch of services (as evidenced by the messages I see). Sure enough, the server no longer responds to any requests. Unfortunately, the java process does not die. I have this problem whether I start Tomcat by hand or if I use the Sysdeo Eclipse plugin. This problem has been a thorn in my side for some time but since it only affects my development environment (we use it as a service in production and there are no problems) and I can kill the process by hand, I've not worried about it. It's annoying as heck though and I'm wondering if someone can shed some light. I searched around but (surprisingly!!)

Re: tomcat detecting http header
Of course, you could just call request.getRemoteAddr();
Tomcat is a Servlet Specification container. You don't get headers with
CGI naming conventions.
Check out the api documentation:
http://java.sun.com/j2ee/1.4/docs/api/index.html
It's the packages starting with javax.servlet that will be of most
interest. Specifically, the docs for javax.servlet.ServletRequest give
some info on methods that map to CGI variables.

Re: Do URL query strings with semi-colons work with TC ?
Aye. It just states for that, amongst others, amphersand and semi-colon are reserved characters within the query string. This got me looking coz I assumed that the structure of the http get query string was defined somewhere in rfc rather than just a convention. I found a few resources saying it was recommended to support ";" as a delimiter; http://www.w3.org/TR/1999/REC-html401-19991224/appendix/notes.html#h-B.2.2 But I also found the likely candidate in TC that does the parsing of the query string: http://cvs.apache.org/viewcvs.cgi/jakarta-tomcat-connectors/util/java/org/apache/tomcat/util/http/Parameters.java?rev=1.15&view=markup Just for my peace of mind does anyone know where the "standard" use of amphersand to delimit name-value pairs in a http get query string is defined? Jon Darryl L. Miles wrote: http://www.faqs.org/rfcs/rfc2396.html section 3.3 seems to be the best reference so far. This RFC only specifies correct URI syntax, it does not mandate how that URI is used under any scheme (like "http:") is to be used. Darryl L. Miles wrote: The reference you cite http://www.faqs.org/rfcs/rfc2616.html (el al) maybe you could also cite the section I should look at. A simple search for "param" or "semi" yeilds no related results. I have spent an hour looking into the issue over the weekend and found the specification that covers the URI scheme for "http:" from this angle it seems to leave the part after the ? to denote the start of a query string vague. Which lead me to a presumption that it was HTTP server dependant on its interpretation, since for example the CGI.pm modules changed over from & to ; as the standard param delimiter with generated URLs, providing the resulting URL talks back to itself (the CGI.pm module) all will be well in the world but if it links to a TC server then there would appear to be a problem. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Do URL query strings with semi-colons work with TC ?
In a URL the semi-colon indicates the start of path parameters (as
opposed to the normal query parameters) as defined in rfc2616 (HTTP1.1
spec) et al.
Thus, you can't tell tomcat to use it as a query string delimiter.
JSESSIONID is a well known path parameter for Servlet 2.2+ Containers.
To use a semi-colon within a url you'll need to url encode it as %3B
To use it in the way you want you'll have to encode and parse the query
string yourself.

Re: http404 error in tomcat5.5.9
I'm not sure the whitespace in your directory structure came out right
so I'll make a few comments:
web.xml should be in myapp/WEB-INF
context.xml should be in myapp/META-INF (or rename it to myapp.xml and
move it to the webapps directory)
Your servlet class should be in a package. Have a look at :

Re: Cannot compile jsp pages with log4j statements -- Tomcat 5.5.9
One major change between the 4.1.x branch and the 5.x.x branch is
packages in generated servlets. In tc4.1.x all the jsps were in the
org.apache.jsp package irrespective of the structure of the site.
From 5 onwards the jsp directory structure is also part of the package
name. So, my guess is agent_report_all_in.jsp is in a different
directory from the one that fails to compile. It works in 4.1 but needs
to be imported in 5.x.x.

Re: sessions dropping with mod_ssl, mod_jk, mod_rewrite rules
I'm pretty sure Tomcat doesn't allow a session to migrate from a secure
(ssl) channel to an insecure one. It does allow the session to be
maintained in the other direction, however.
The rationale for this behaviour is that if the login is supposed to be
secure why allow the session cookie to be snooped on an insecure channel.
Doing a cursory search of the archives I found these threads:

Hi, there. I have a problem whereby tomcat is getting confused with user
sessions due to (I think) some mod_rewrite rules that switch a user in and out
of SSL. The general requirement I have is to only use SSL in certain parts of
our application (login, user administration, etc), and we use mod_rewrite rules
to enforce this. The problem is that while we can correctly make sure a user
login is properly redirected to SSL, when that user clicks on a link following
login (ie: a non-SSL request), they are sent back to the login page. This is
due, I think, to tomcat confusedly thinking the subsequent request comes from a
new, unauthenticated user, possibly because the second request is not over SSL.
When I run an HTTP tracer, I indeed see that there is a new session cookie
placed for the subsequent request.
Below is the relevant portion of our httpd.conf file, followed by the
workes.properties file. I've followed the recommendations I've seen online
regarding connector configuration, but perhaps there is something subtle that
is missing, or our rewrite rules are screwed up. Any insight is appreciated.

Re: load on startup
Use a ServletContextListener, they were added to the Servlet 2.3 spec for this very purpose. You set up your object in the contextInitialized(...) method of your implementation and tear it down in contextDestroyed(...). For it to be used you need to add it to your web.xml. The container is free to init and destroy servlets as it sees fit after complying with load-on-startup directives. That's why use of load-on-startup for initialization of application scope objects is prone to error and unforeseen circumstances. my $0.02 and HTH, Jon Nicolas Schwartz wrote: Hi all, I need an object to be instanciated on the startup of my tomcat.

Re: Caching static content -> Bug in Filter implementation?
I think that's expected behaviour: You can't set headers after the response has been committed (more body data has been written to the outputstream than the buffer size). In the case of the 200 response code the call to filterChain.doFilter(...) actually serves the content. Setting of the header after this is too late. Jon [EMAIL PROTECTED] wrote: Hello I do some further analysis in this problem and got following result: Precondition: The filter manipulates the HTTP header when returning a static resource (e.g. image). HTTP 200 In case of a HTTP 200 (OK) result the header is not added when the doFilter method is like following: filterChain.doFilter(request, response); response.setHeader(name, value); In contrast to it works when the code is like following: response.setHeader(name, value); filterChain.doFilter(request, response); In other words: When returning a HTTP 200 (OK) I must set the header before forwarding the request to the next filter. HTTP 304 In this case it doesn't mention whether setting the header is before or after forwarding the request. Any comments?

Re: Implementing my own realm
We've implemented our own realm. The step's are quite easy: 1) Implement your custom Realm, we subclassed RealmBase. 2) compile your Realm class with catalina.jar in the classpath 3) jar up your Realm class and any helper classes 4) deploy realm jar to server/lib The only thing you really need to worry about is classloader issues: try to keep any references to your webapp classes out of the Realm and just deal with standard types like Principal otherwise you could end up deploying half your webapp classes to common/lib.

Interesting question.
The Servlet 2.3 spec says:
"
public boolean isRequestedSessionIdFromURL()
Checks whether the requested session ID came in as part of the request URL.
Returns: true if the session ID came in as part of a URL; otherwise,
false"
I would interpret it this way: if the session id, which should be used
was extracted from the URL, then return true.
If however the cookie contains the same id and was checked first (which
is default I think) then the requested session id came from the cookie!
Imagine what would happen if always both would be checked and URL and
cookie would contain 2 different ids.

Re: Getting DBCP Exception
Ajay, That's a mySQL error message. In the jdbc url you can add parameters to automate reconnection: autoReconnect should the driver attempt to re-connect if the connection dies? (true/false) -> false maxReconnects if autoReconnect is enabled, how many times should the driver attemt to reconnect? -> 3 initialTimeout if autoReconnect is enabled, the initial time to wait between re-connects (seconds) -> 2 If you've already have this set, do you see the Exceptions when/after you bounce the database? I think you can also see this error message if an admin kills a running database query from the processlist - the client thinks the database has gone away. If the above aren't the problem then maybe the communication between the client and mysql server isn't "fast enough". You may have to tweak the client and server connection timeout parameters (in my.cnf in the server). You can also configure DBCP to give a pooled connection a kick to stop it timing out (mysql times out idle connections after, IIRC, 8hrs by default).

Re: JMX implementation - Tomcat 5.0.28
That's because it's hardcoded to look for jmx.jar. One jar, singular.
Sitting on my local dev machine I've got a jmx.jar which is a
concatenation of mx4j.jar and mx4j-tools.jar. It's a bit horrible but it
works.
There are other ways to do it:
1)
Add your jars to the bootstrap classpath by modifying setclasspath.bat
(assuming you're using the scripts not the service to start and stop tc).
2)
According to the release notes you can also change the manifest file in
the bootstrap.jar to point to your own jmx implementations.

Re: Tomcat banner
The ability to change the Server header in a filter depends on the connector. The Coyote connector uses the response.addHeader(..., ...) variant so you get your custom header AND coyote's: HTTP/1.1 304 Not Modified Server: IMP/4.1 Date: Tue, 17 May 2005 08:54:10 GMT Server: Apache-Coyote/1.1 A custom Valve may be able to correct this, the RequestDumperValve log shows both values, because it can execute late enough in the response chain. In production we have Apache in front of Tomcat connected using mod_jk2 and the client never sees our custom header. I haven't yet looked into whether the final setting of the header occurs on the apache side or on the tomcat side. (I'm assuming it's the Apache side.)

Re: Overriding the browser language setting?
One solution would be to map a Filter to whichever URLs you wish to override the browser settings. In the Filter wrap the request, using a sub-class of javax.servlet.http.HttpServletRequestWrapper, before passing the request to the rest of the chain. In your wrapper sub-class override the methods getLocale() and getLocales() and you should be set. see: http://java.sun.com/j2ee/sdk_1.3/techdocs/api/index.html HTH, Jon Kurt Overberg wrote: Hi there all!

Re: Trouble with JDBC (I need a little help)
It's a NullPointerException causing all your woes. In the Connect method
of DBConnection you are assigning to a local variable of type Connection
instead of the instance variable. The instance variable is always null,
which causes issues in the QueryDataBase and TotalRows methods.
The code as it stands is rather flaky, I'm afraid.
Look into connection pooling (docs on the tomcat site and many posts
related to it on this list) and defensive programming (checking for null
values etc, etc). Also, Wolfgang's advice is good: always close
ResultSets and Statements after you're done with them (and connections
for that matter).

Re: Servlet Streaming file to client: Can't override file name
What happens in FireFox if you do this:
response.setHeader("Content-Disposition", "attachment;
filename=\"" + theFile.getName() + "\"");
The relevant spec is here:
http://www.ietf.org/rfc/rfc2183.txt
And for the definition of 'value' it references:
http://www.ietf.org/rfc/rfc2045.txt
The filename parameter must be quoted if it contains spaces.

Re: R: Tomcat 5 java.lang.outOfMemory

The best answer is to test whether you actually need more memory or whether you are leaking it somehow. So find a profiler, get it to talk to Tomcat, and then run your JSP and watch the method call tree, heap monitor and hot spots etc... You will need to grab something like JProfiler, JProbe or others ... they usually know how to connect to Tomcat 5 for you, it's not too hard. Also, you may want to upgrade your Tomcat I think 5.0.19 had an issue anyway with memory, and finally you'll want to ensure when dealing with database connectivity that you are freeing up resources like result sets and so on with close() calls (depending on what you are doing).

Re: TC Drops bytes when client uses Chunked Encoding AND specifying Content-Length at the same time.
Section 4.4 of rfc2616 (HTTP1.1 spec) has rules for message-length processing. Rules 2 and 3 seem most pertinent. 2.If a Transfer-Encoding header field (section 14.41) is present and has any value other than "identity", then the transfer-length is defined by use of the "chunked" transfer-coding (section 3.6), unless the message is terminated by closing the connection. 3.If a Content-Length header field (section 14.13) is present, its decimal value in OCTETs represents both the entity-length and the transfer-length. The Content-Length header field MUST NOT be sent if these two lengths are different (i.e., if a Transfer-Encoding header field is present). If a message is received with both a Transfer-Encoding header field and a Content-Length header field, the latter MUST be ignored. Looks like a bug in both TC and the client: TC should ignore the Content-Length as per rule 3. The client shouldn't be sending both headers as the lengths of the entity and transfer are different. Jon Ian Huynh wrote: We are using TC 5.0.28 on JDK 1.4.2 We have a client who POST to TC using header "Transfer-encoding: chunked" and at the same time specify the "Content-Length" header when posting to us. It seems that if the Content-Length is specified, TC is dropping the last few bytes..?? This same customer claims that his code works with the Jetty Servlet (which is the old embedded servlet in JBoss 3.2.1 and earlier). We have done some prelim testing and confirmed that a) if Content-Length is NOT specified and Chunked encoding is used, TC works as specified. b) Jetty works either way (with or without Content-Length). My questions are: 1. what is the correct behavior in HTTP 1.1? I've read through the spec but am unable to ascertain whether or not Content-Lenght should NOT be used when chunked encoding is used. 2. Is this a bug in TC? Unfortunately, our client isn't able to modify the code to NOT include the Content-Length or NOT use Chunk encoding Thanks in advance - 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]

[OT] Re: wrong time in Java Applications to my location (new Date())
The default timezone of a Sun JVM is determined by user locale settings. If the runtime can't determine a sensible timezone from those it defaults to GMT, which is 3hrs off from Brazilia time, i think. Looking at the source of TimeZone it uses the following system properties: user.timezone user.country java.home If user.timezone is not set then a native call is made using user.country and java.home. I'm not sure what happens for a multi-timezone country like Brazil ;) So you could: 1) pass in the user.timezone system property to the runtime. 2) Set your servers default timezone in code: TimeZone.setDefault(TimeZone.getTimeZone(id)); where id is one of: Brazil/DeNoronha America/Sao_Paulo (probably the one you want or maybe Brazil/East) America/Boa_Vista Brazil/Acre or America/Rio_Branco Are you running Tomcat as a service? If so, you may also want to check that the regional settings for the user running the service are also set to Brazilia. I would also check what is actually being determined by the JVM.

Also from Section 14.36 of rfc2616: The Referer field MUST NOT be sent if the Request-URI was obtained from source that does not have its own URI, such as input from the user keyboard.

It worked when coming from my pages but I then tried going to another page (e.g www.sun.com) and then pasting in the url and it just returned null. Does referer only apply when hyperlink from another page ? Some browsers, including IE, are known to have bugs regarding the referrer header.

You are calling getWriter in your catch clause after you have already

Re: Fw: Internet Explorer Bug under SSL Connection
Tomcat adds (or at least did in the 4.1 branch) certain response
headers, directives to clients and proxy caches to not cache the data,
when it is to serve something within a security-constraint. (log
examples at end of post)
[It seems that] When IE downloads something with a mime-type it thinks
it can handle (probably via a plug-in) it caches the data and then
passes it over to the plug-in. With SSL and the Pragma header set to
no-cache this seems to fail with the error message described in the
original post.
Our entire site is SSL also and we've seen this error (and our hack
resolves it) for csv, excel, pdf files. Downloading with the
content-type set to application/octet-stream doesn't trigger the error
in our experience (we also provide this option on the download pages but
users generally want to see the data directly).

Re: Servlet caching?
One thing you might want to check is that whatever PrintService SPI implementation is looking up your printers doesn't cache the result for the lifetime of the JVM.

If so, you might want to change it so you can: 1) list the printers 2) install the new printer while the app is still running 3) list the printers I just did a (rather noddy) check on my workstation: I brought up the print dialog in JEdit and saw just one printer. I installed a new printer then opened the print dialog again and saw just one printer. I restarted JEdit and voila: two printers. I assume JEdit is using the default PrintService discovery mechanism supplied by the JVM. On my workstation that's sun.print.Win32PrintServiceLookup as defined in META-INF/services. If the default implementation is caching then you are out of luck unless you want to write your own PrintServiceLookup.

Re: method level synchronization doesn't work
I'd be surprised if synchronization was broken. Given one assumption I
think I can explain what you are seeing.
Assumption: The two concurrent requests are handled by two different
instances of a jsp servlet.
If there are two instances then each request will be able to
sucsessfully obtain the monitor when calling the synchronized methods.
So, why does using a synchronized block work? It works because you are
synchronizing on a literal string. Literal strings get interned into a
pool of objects by the jvm. So the mutex reference actually points to
the same piece of memory for both instances of your jsp. Hence the
synchronization works.

Actually, the data that I am modifying requires a transaction and

have to do a select to get the current value, increment the counter, and

time, the counter will not be properly incremented. What's puzzling is that
method level synchronization does not work while synchronizing on a block of
code inside a method works.

am I missing something, but looks like you're trying to build some
kind of web cache. why not use Hibernate or something that already
does caching for you instead?
the only time I can see a need to sync, is if the request contains
data that requires a transaction. Which in that case, you're better
off doing an insert, then a second select query with the same
connection.
or is the scenario a distributed objects setup?

Re: IE6 and download problem using tomcat java servlet
IE feels the need to cache the content before saving it to the desired
location. You probably have some headers in the response designed to
stop caching. You could comment in the RequestDumperValve to confirm this.
Add to your code:
response.setHeader("Pragma", "public");
We saw similar problems for downloads from urls within our
security-constraint. They went away when we added this header.

Re: How to write a Valve that can inspect the HTTP Body, without damaging the InputStream?
Can't you use a java.io.PushbackInputStream? You could write a Filter instead of a Valve. In the Filter wrap the ServletRequest and provide a custom ServletInputStream which uses the PushbackInputStream around the real ServletInputStream. Once security checks have passed you can push back the used bytes and pass on your wrapped ServletRequest down the Filter chain to the 3rd party servlets. HTH, Jon Betts, Chris wrote: Hi Folks, I want to write a tomcat security Valve that does content checking of the HTTP body, before anything else happens (e.g. 3rd party destination servlets I have no control over are called).

Unfortunately, the data is actually HTTP POST data containing SOAP/XML, otherwise I could use the servlet request parameter methods. Since it is SOAP/XML though, I really have to get the body data directly, as no parameters are set.

Re: explorer can't open protected files but mozilla can
This has come up several times recently. It's all to do with how IE handles content. It seems, whenever a plug-in is used (excel, word, acrobat etc) IE has to download the content to its cache before the plug-in can be passed the content. So, when content is served from a protected area Tomcat adds http headers so that the content is not cached at proxy or browser level. This causes IE problems ;) We've solved this by selectively changing the http headers that go with content served to IE. This solution is detailed in the thread titled 'Tomcat 4.1.30 adding no-cache to http headers' on this list from last week. You'll have to write and deploy a Filter to modify the headers but it's not hard. HTH, Jon Janko Harej wrote: Hi! I have a web application with a protected folder and some files in it.

Re: Tomcat 4.1.30 adding no-cache to http headers
I'm sure I said use a Filter mapped to your download urls ;)
The filter gets executed before tomcat's default servlet serves the
content. The Filter itself would be pretty trivial, just place the code
I posted in its doFilter(...) method and map it to *.doc in your members
context.
Maybe it's more work than you were hoping for but considerably less than
rewriting Tomcat's default servlet or tinkering with the code of the
SingleSignOn feature.
Good luck,

In all places on our site where pdf, excel, word docs etc can be

Is there anyway I can remove these headers for the /members context. I'm basically
using tomcat in place of Apache's .htaccess files, since I need to use tomcat's
single-signon for other *real* applications.
Thanks,

Re: Tomcat error
The 49.0 is a magic number within the class bytecode. This type of error typically means the class was compiled using a newer version of the jdk than the runtime that is interpreting the bytecode. So, did you, say, compile the lawSearch class using jdk 1.5 but are running Tomcat against jdk 1.4? Resolution: recompile lawSearch against jdk 1.4 http://java.sun.com/docs/books/vmspec/2nd-edition/html/ClassFile.doc.html#75883 HTH, Jon Schalk Neethling wrote: Hey there all I get the following line when running my servlet on Tomcat version 5.0.25: java.lang.UnsupportedClassVersionError: org/volume4/searchEngine/lawSearch (Unsupported major.minor version 49.0) What exactly does this mean and how do I go about fixing this?

Re: Rewriting URLs in Tomcat
sendRedirect(...) tells the browser to use a resource in a different location. That location can be same webapp, different webapp, different server. forward(...) is for the same server only. In context: servletContext.getRequestDispatcher(path).forward(...); Out of context: servletContext.getContext(foreignContextName).getRequestDispatcher(path).forward(...); For forwarding to a different context you have to have the relevant permissions or the servletContext.getContext(foreignContextName) call will return null. In tomcat the context doing the forwarding has to be marked as crossContext: http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/context.html Jon PS the chained invocations above are illustrative only, not as I would normally code it ;) Jacob Weber wrote: Tim Funk <[EMAIL PROTECTED]> wrote: At http://funkman.home.comcast.net/ I have a project called ServletUtils.

Re: Mysterious null pointer exception
Your instance variable conn will always be null.
In your init method you are assigning the result of the
ds.getConnection() to a local variable. Change it from
>Connection conn = ds.getConnection();
to
>conn = ds.getConnection();
and you may be ok.
Of course, conn may also be null if your servlet can't find the
jdbc/empdb datasource...

Re: tomcat hangs, top displays 99%
Just a thought. Does your error page also have header.jsp included? Have you got yourself into an infinite loop of "Session already invalidated" IllegalStateExceptions?

Re: Pass info between Tomcat Valve and Filter
Cool. I guess a Valve is good for that type of thing :) I think Carl and Ralph are right about the ClassClassException being a ClassLoader issue. I've seen similar things before when using custom Realms, JNDI resources etc. Our build process generates a minimal jar for deploying to common/lib which contains all the classes needed by the container classloaders. These classes are excluded from the webapp jars and all is happy. You have to be really careful about dependencies though or virtually all your webapp ends up in common/lib. Try jarring up your info object and putting in common/lib (or common/classes). Or you could use reflection as I've just read in your reply to Ralph ;) Good weekend all, Jon Rui Zhang wrote: Jon, To answer your query, I'm using a custom valve to instrument Tomcat with response time monitoring, as part of the project I'm working on... http://web.comlab.ox.ac.uk/oucl/research/areas/softeng/eWLM/ Cheers, Rui On Fri, 21 May 2004, Jon Wingfield wrote: An invocation of a Tomcat Valve gives you a Request object.

Re: ClassCastException with own Principal interface and implementation
This is probably a classloader issue. The Realm will load classes from the server classloader. Your webapp will also load the same classes in its own classloader. The two types of CrmPrincipal are not assignable so a ClassCastException results. Try placing the CrmPrincipal class in common/lib and removing it from your webapp. HTH, Jon ralf lorenz wrote: hi there, i've written my own realm 'CrmJDBCRealm' which extends the 'JDBCRealm' one of catalina. this realm creates and returns a principal of type 'CrmPrincipalImpl' which extends 'GenericPrincipal' and implements 'CrmPrincipal'. 'CrmPrincipal' has getter for an 'id' and getter and setter for a 'currentRole' field and extends 'Principal' as well as 'GenericPrincipal' does. 'CrmJDBCRealm', 'CrmPrincipalImpl' and 'CrmPrincipal' are packed together into a .jar and placed under %CATALINA_HOME%/server/lib on the other side the application only has the 'CrmPrincipal' included, so it doesn't know about 'CrmPrincipalImpl'. (even if it does nothing changed!) in my application i have a 'ChangeRoleAction' that is supposed to update the 'currentRole' if the user decides to have, only application-wide, another role. again that's nothing to do with the roles of the user that are known by the server via the 'GenericPrincipal'. when i try the following i get an ClassCastException CrmPrincipal principal = (CrmPrincipal) request.getUserPrincipal(); printing out the name of the class the request gives the 'CrmPrincipalImpl' will be stated. so the realm works fine but the cast can't be done. any help? ralf - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

The answer's in the question ;)
Tomcat is not a J2EE Server but an implementation of the Servlet
Specification (which is but a part of the whole J2EE spec).
Tomcat's JNDI lookups are in-process only.
Need an open source J2EE container? Have a look at JBoss...

There's a code snippet.
Context initCtx = new InitialContext();
UserTransaction tx =

Re: Getting Context Parameters from server.xml
Oops. Sent too soon. That code would only work if your parameters were
set up in you web.xml not server.xml
ie
companyName
MyCompany
The original code was looking up the servlet's init parameter, which
should be defined:
param-servlet
com.MyCompany.ParamServlet
companyName
MyCompany
These are portable ways (servlet spec compliant) to pass parameters to
webapps.
The tags within server.xml are related to Resources (Data
Sources etc) and probably not what you want.

Re: tomcat4.1 for windows,pl
I just looked at the code you posted. I think it's a
NullPointerException within line 33 of your LoginServlet
int kode = Integer.parseInt(request.getParameter("kode"));
This will throw an NPE if the "kode" parameter is not set...
Is your MIDLet TextField empty when you get this error?
If not, check that your MIDLet code is properly generating an HTTP POST
request (you're not setting the content-length header, there needs to be
a blank line between http headers and the body etc). Turn on the
RequestDumperValve in your tomcat's server.xml to check what tomcat
receives...

When I checked the web descryptor of the example

Re: webapps\ROOT\WEB-INF\classes
I'm fairly certain classes deployed to \WEB-INF\classes have to be in packages. So your Fruit class should be deployed to \WEB-INF\classes\com\stevensons if the Fruit class is in the com.stevensons package. In your jsp you also MUST import the class you want to use. eg: <%@ page import="com.stevensons.Fruit" %> see the following (non-exhaustive) list for more details: http://jakarta.apache.org/tomcat/tomcat-5.0-doc/appdev/index.html http://www.jcp.org/aboutJava/communityprocess/final/jsr154/ HTH, Jon Colin McKinstry wrote: I've tried setting the class_path to \webapps\ROOT\WEB_INF\classes in the Windows environment variables, but that hasn't improved matters :-( Anyone got any ideas? -Original Message- From: Wendy Smoak [mailto:[EMAIL PROTECTED] Sent: Wednesday, 10 March 2004 8:57 a.m. To: Tomcat Users List Subject: RE: webapps\ROOT\WEB-INF\classes From: Colin McKinstry [mailto:[EMAIL PROTECTED] The only thing I've done configuration wise is define CATALINA_HOME & base.

Re: The purpose of WEB-INF\classes ?
WEB-INF/classes takes precedence over WEB-INF/lib in the servlet spec: 2.3fcs, section "SRV.9.5 Directory Structure". If WebLogic 6.1 behaves differently then it's another spec violation ;) Jon Justin Ruthenbeck wrote: To you (the end-user), there's no purpose for it other than convenience. One thing to keep in mind is that classes in the /classes directory take precedence over those in jars found in the /lib directory (in Tomcat -- is this a spec thing? I'm assuming not as WL61 at lease doesn't do this), which is an important distinction that makes the difference more useful. As for why it's useful, if you're developing an app and are constantly compiling and testing, why should you have to jar them up each time you compile the classes? Just stick them in the /classes dir. On the other hand, releasing and versioning code is much easier as a jar. Give people flexibility and they'll come up with new and wonderous things... justin At 05:45 PM 3/1/2004, you wrote: This is not a question to fix a problem other then one in my head. I am not sure what the difference is putting a jar in a \WEB-INF\lib and setting up a \WEB-INF\classes. Since a jar usually just includes class files if we put a jar in the webapp's \WEB-INF\lib what would be the purpose of setting the tree of classes expanded in WEB-INF\classes? Let me give an example. In Tomcat 4.1.30 there is a server folder. Under this exists webapps. And then under this are two folders admin and manager. Looking at the admin webapp you will find its WEB-INF and under that it has a lib and a classes folder. The lib folder contains just one jar, ie: struts.jar. But the classes folder contains the tree of what looks to me is the structure of a jar ie; org | apache | webapp | admin| ... I am not sure if this is just an expanded struts.jar but it looks to be. If not struts.jar then likely some other jar. So my question is what is the purpose of having an extracted jar structure under a classes folder? I have made my own webapp but I do not have a classes folder under that because I have yet to come across the purpose of when it is necessary?

Re: IOException while loading persisted sessions continued..
Did you read as far as the NotSerializableException bit? ;) If you don't want to make MyLinks serializable but want Tomcat to serialize sessions you could (amongst other things) implement a HttpSessionActivationListener. Add this object to the session at the same time as your MyLinks object. When tomcat serializes the session to disk the sessionWillPassivate() method will be called. In that method you could remove the MyLinks object from the session. When the session is restored you could re-init MyLinks in the sessionDidActivate() implementation. HTH, Jon Allistair Crossley wrote: It says "Classes that do not implement this interface will not have any of their state serialized or deserialized" So, to me that means I do not have to put Serializable if I do not want my MyLinks class to be persisted.
