How to disable PUT, DELETE http methods etc if not using container managed security?
Is there a way to prevent PUT or DELETE http methods if you're not using container managed security? If so, how? I already have this to force the use of https: Protected Context /* CONFIDENTIAL What changes are needed? I tried this but it didn't seem to work: Protected Context /* HEAD <-- PUT<-- DELETE <-- TRACE<-- OPTIONS <-- CONFIDENTIAL Inserting these statements seems to turn off the automatic enforcement of https which was achieved with the first version. Any ideas? Thanks
Re: Arabic encoding
I use oracle 7 database, and the NLS language is American_America.US7ASCII, and it is not easy to change it to utf-8. Beside, the question is, a servlet work fine on tomcat 4.0.6 why it stopped with the new versions, what changes made to the encoding of tomcat?? do I need tomcat-i18n-ar.jar? and if so, from where to get it? I can't determine where is the problem, is it from the new Java or the new tomcat. thanks in advanced - Original Message - From: "Benson Margulies" <[EMAIL PROTECTED]> To: "Tomcat Users List" Sent: Wednesday, February 23, 2005 11:26 PM Subject: RE: Arabic encoding What database?

Interesting... do you have any recommended reading on that, Graham?
Love these urban-legend types of warnings ("don't flash your
headlights...").
I think Graham is referring to a bug in the 1.4.2 line of JVMs where
under certain circumstances, the HotSpot compiler trips over the garbage
collector, and causes mysterious VM aborts. I believe there have been
fixes in 1.4.2_06 and 1.4.2_07, and also in 1.5.0_01.
It's triggered more easily in an HT or MP machine, but the important
thing is that it can also be tripped on non-HT, single-processor
machines (though much more rarely).

JK2 Failover Problem
I'm having trouble with the failover functionality of JK2. I have apache connected to two back-end tomcat engines running on separate machines. The failover works just fine when a tomcat engine dies. The node is not given any requests and the webapp continues to function normally. However, when an individual webapp dies I get problems. Apache continues to send requests to the non-functioning webapp, even if the app is not even deployed on that tomcat instance. I was under the impression that jk2 would take this into account, but it appears that it either doesn't or I don't have it set up to do this. any help would be greatly appreciated.

Parse/read an XML doc with encoding Shift_JIS adds characters (2nd email)
I am using a GetDictionary.jsp script to parse an XML document containing simple Japanese phrases encoded with Shift_JIS. What I observe is that after reading a phrase into a java.util.HashMap bean the phrase becomes longer and modified (really, corrupted). This (corrupted) phrase sent in an HTTP reply, is modified again inside the packet. Example: 1. the original phrase (in binary), from the XML doc: be dd c0 b8 bc c3 b8 c0 de bb b2 2e 2e 2e 2. the phrase (1) logged from a HashMap object: efbf bd efbf bd 38 efbf bd c3 b8 efbf bd de bb efbf bd 2e 2e 2e 3. the phrase (2) in an HTTP reply: 21 29 21 29 38 21 29 21 29 21 29 21 29 21 29 2e 2e 2e It appears as if two transformations were going on, beyond the GetDictionary.jsp control. Interestingly the last three characters 2e 2e 2e (='...') are preserved all the way. Another script Send.jsp that sends a reply has the following page declarations: <%@ page pageEncoding="Shift_JIS"%> <%@ page contentType="text/xml; charset=Shift_JIS"%> The situation is the same bad if only one declaration is in the Send.jsp: <%@ page contentType="text/xml; charset=Shift_JIS"%> Does anyone have a suggestion what am I doing wrong? Especially - while is there a 'transformation' from the XML doc to the HashMap? And then, why is there a second 'transformation' into a packet? Thanks, Jerry. [By the way, the same GetDictionary.jsp works fine if the parsed/read XML document is utf-8 encoded, or ISO-8859-1 encoded, or ascii. The phrase in the HashMap object is binary identical with the original phrase from the XML doc. Then it is the same in the reply packet (sent with a script having declared a corresponding charset).] - 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: Trying to understand exceptions and
Part of the spec says "if no error-page declaration containing an
exception-type fits using the class-heirarchy match, and the exception
thrown is a ServletException or subclass thereof, the container extracts the
wrapped exception..."
So supposing for a minute that Tomcat internals "ignore" any error-page that
has exception-type 'ServletException', it would then proceed to unwrap the
exception to get down to your DAOException. Which you've already proved that
you *can* catch.
I've successfully caught 'all other' exceptions (which I suppose must
include ServletExceptions), by using one error-page declaration that catches
500, and then multiple 's to
catch more specific exception types.
This is all on TC5.0.28 (TC4.x seemed a bit flakey on exceptions and
errorpages, but that could have been PEBKAC)

Trying to understand exceptions and
With nothing configured for errors, I get a Tomcat error page:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it
from fulfilling this request.
exception
javax.servlet.ServletException: org.xml.sax.SAXParseException: blah, blah...
...
root cause
com.example.DAOException: org.xml.sax.SAXParseException: blah, blah...
...
Caused by: org.xml.sax.SAXParseException: blah, blah...
The code that causes it looks like this:
try {
...
} catch ( Exception ex ) {
throw new DAOException( ex );
}
Can someone explain why, if I put this in web.xml,
javax.servlet.ServletException
/WEB-INF/jsp/error/exception.jsp
it does NOT display the .jsp and instead shows the same thing as above with
all the stack traces?
I also tried configuring it for java.lang.Exception, but no luck there,
either.
I _can_ get a good error page if I configure it for the 'root cause'
DAOException, I'm just confused as to why I can't trap the ServletException.
Thank you,

Service automatically shuts down on Windows Server 2003
I apologize for not doing as much homework as usual before posting a question. Google turned up nothing helpful, the mailing list archive search isn't working right now, and we're (of course) in a hurry. We've had Tomcat 5.0.19 working on a number of Windows machines for a while, running on Win2K and WinXP under j2sdk1.4.2_04 Yesterday we had to install it on a Windows Server 2003 machine, and it's not working as a service. If we run it from the shell, it works fine, but when we try to start it as a service, it starts up and shuts right back down with a Windows message that some services don't stay running if they have no work to do. Is there something obvious I should be doing? Or something less than obvious? Even something obscure? :-) I've never had any Tomcat problems; it's a great tool that has always just worked for me. But that means I don't really even know where to begin looking to solve this. Are others successfully running Tomcat on Windows Server 2003?

SSL Client authentication against MemoryRealm
Hi, The SSL client authentication doesn't work agains MemoryRealm, because the authentication mechanism passes the DN of the client certificate to the realm after validation for role assignement, but the memory realm don't allow usernames that contains "," or "=" characters. Because the DN contains these characters, the user can't get authenticated. I haven't tested this with other Realms, but it's important to fix it on MemoryRealm, used primarily for testing purposes. The tomcat version with I'm using is 5.0.16. Greetings -- Jesus De Oliveira Consultor IT Baysystem Consultores C.A.

Re: Starting up Tomcat when the Linux starts up
There should be an example tomcat5.sh with your distribution of jsvc. If not, download the most recent release from the Commons Daemon project at jakarta.apache.org and get a copy from there. Customize it with the options you use and you should be good to go. Splitting out put between console and log: check your linux man pages for the tee command.

Re: How to send hidden variables to next page
I dont know but looks like you are doing somethings wrong... hidden
fildes are a great choice... better them use GET method...
About the table think... use Iframe and do a submit to it...
Whem you submit you use normal submit button or javascript???
If you are submiting with normal button try to use Javascript is much
better! Example:
function submitform()
{
// FOR LOCAL FORM... where the form name is "myform"
Âdocument.myform.submit();
//OR FOR IFRAME FORM... where the IFRAME name is myframe and the FORM
name is "myform1"
window.frames.myframe.document.myform1.submit();
}
SUBMIT HERE!!!
You can also make MANY variations on it... like pass values in the
function from the external frame to a filed on iframe.
Example:
function submitform(val1)
{
//CHANGE THE VALUE OF A FIELD ON IFRAME... where myfield is the name of
the filed...
window.frames.myframe.document.myform1.myfield.value=val1;
//FOR IFRAME FORM... where the IFRAME name is myframe and the FORM name
is "myform1"
window.frames.myframe.document.myform1.submit();
}
SUBMIT HERE
I make some dynamic tables based on users choies! Works very well.

The best advice I can offer -- have a javascript
that does the submit
for you on the event the drop-down changes state.
Then let a servlet
handle storing your form data in the session and
passing updated data to
the next page. Outside of something like that, I
think you'll need to
incorporate a submit button.

Multiple mappings to same servlet query
Hi I know that if I have multiple mappings to the same servlet, then I get two seperate objects instantiated. However, where does the engine instantiate the copy from? For example, I want to run two copies of the same servlet with different URLs, one in test mode, one in live mode. I was planning on configuring a different set of parameters for the two cases in my web.xml file but I need to be sure that I will get two instances, each with its own set parameters rather than the engine "cloning" a copy of the servlet it has already loaded.

For the table issue you need to use DHTML along with Javascript.
there will be some sample code available in the net.

Tomcat 5.5.7 using builtin JDBC connection pool, can't access 'real' connection - accessToUnderlyingConnectionAllowed=true
Hi there,
did anybody manage to access the underlying 'real' database connection?
I have got to use the PostgreSQL LargeObject API and therefore I need access to
the delegated connection.
But after several hours of trial and error I lost my motivation ... It seems
like:
- doesn't do anything:
- always returns 'false':
org.apache.tomcat.dbcp.dbcp.PoolingDriver.isAccessToUnderlyingConnectionAllowed()
.
- doesn't do anything:
org.apache.tomcat.dbcp.dbcp.PoolingDriver.setAccessToUnderlyingConnectionAllowed(true);
- also doesn't do anything:
dataSource.setAccessToUnderlyingConnectionAllowed(true)
At last I found some kind of workaround, which is indeed not really desirable
...
Accessing an org.postgresql.PGConnection via a statement works ...
Maybe someone can help me.
Bye,
Bernd.
code snippet:
import org.apache.tomcat.dbcp.dbcp.PoolingDriver;
import org.apache.tomcat.dbcp.dbcp.BasicDataSource;
import org.apache.tomcat.dbcp.dbcp.DelegatingConnection;
import org.apache.tomcat.dbcp.dbcp.DelegatingStatement;
import org.postgresql.PGConnection;
...
logger.debug("PoolingDriver.isAccessToUnderlyingConnectionAllowed:
"+PoolingDriver.isAccessToUnderlyingConnectionAllowed());
PoolingDriver.setAccessToUnderlyingConnectionAllowed(true);
BasicDataSource dataSource = (BasicDataSource)envContext.lookup("jdbc/website");
logger.debug("dataSource.isAccessToUnderlyingConnectionAllowed:
"+dataSource.isAccessToUnderlyingConnectionAllowed());
dataSource.setAccessToUnderlyingConnectionAllowed(true);
logger.debug("getting delegating connection");
DelegatingConnection connection =
(DelegatingConnection)dataSource.getConnection();
logger.debug("getting 'real' connection");
logger.debug("connection.getDelegate(): " + connection.getDelegate());
logger.debug("connection.getInnermostDelegate(): " +
connection.getInnermostDelegate());
// for some reason this works:
DelegatingStatement stmt = (DelegatingStatement)connection.createStatement();
PGConnection pgCon = (PGConnection)stmt.getDelegate().getConnection();
stmt.close();
logger.debug(pgCon);
..
corresponding output:
"PoolingDriver.isAccessToUnderlyingConnectionAllowed: false"
"dataSource.isAccessToUnderlyingConnectionAllowed: false"
"getting delegating connection"
"getting 'real' connection"
"connection.getDelegate(): null"
"connection.getInnermostDelegate(): null"

Hi, One thing to look out for would be the use of JNI i.e. native calls. I'm not sure if there is a way of preventing someone from packaging a .so in a WAR and then loading it in to the app via code to bypass the lack of LD_LIBRARY_PATH (on *nix). didn't try it myself, but I guess /tomcat/conf/catalina.policy and it's java.security settings are the right place to look for these remaining problems.
