Your problem is that you're trying to generate binary data using JSPs. You can't do that, basically (Jasper will always use a Writer, and it will also always set the encoding). I'm sure you can hack your way around by using the right encoding, but you should really use a servlet. There's a fix for you though: you can use revision 1.30 or Response, which strips out the charset if it's the default encoding.

RE: Intro/question possible buglet with Content-Type and Charsets - now more of an RFC
Hi All,
(We may be barking up the wrong tree here, so if so please point me in the
right direction)
This is still causing us issues - as IE fails to parse a charset when it is
tacked on to Content-Type: application/vnd.ms-excel
It would appear that the charset is being tacked onto the Content-Type in
setContentType method of
catalina/src/share/org/apache/catalina/connector/ResponseBase.java in the
event of it not being supplied in the Content-Type (it looks for a ';')
The encoding can never be null as it is extracted from the locale in the
setLocale method below it.
I understand this to mean that the charset will always be tacked on
irrespective of the Type.
However;
I cannot find an explicit reference to not defining a charset for binary
Types, but I cannot see why you would want to.
HTTP 1.1 implies that there is a default charset for text Types (makes
sense)(http://www.w3.org/Protocols/rfc2068/rfc2068)
'When no explicit charset parameter is provided by the sender, media
subtypes of the text type are defined to have a default charset value of
ISO-8859-1'
Which I understand that it is fair enough to add it to text/* Types.
RFC 1341 (http://www.faqs.org/rfcs/rfc1341.html) states that:
'2.a. A text Content-Type value, which can be used to represent textual
information in a number of character sets and formatted text
description languages in a standardized manner.'
But no mention of Charsets in Application types:
'2.c. An application Content-Type value, which can be used to transmit
application data or binary data, and hence, among other uses, to
implement an electronic mail file transfer service.
What I would suggest is a little if wrapper to only add a default if the
Content-Type is text/
A sudo code below (not tested)
###
catalina/src/share/org/apache/catalina/connector/ResponseBase.java
public void setContentType(String type) {
if (isCommitted())
return;
if (included)
return; // Ignore any call from an included servlet
this.contentType = type;
if (type.indexOf(';') = 0) {
encoding = RequestUtil.parseCharacterEncoding(type);
if (encoding == null)
encoding = ISO-8859-1;
} else {
if (encoding != null type.startsWith('text/'))
this.contentType = type + ;charset= + encoding;
}
}

Hi All,
Quick intro, and then a question;
We use tomcat to host java web applications at our

it can be a documentation intensive process (evidence

). So we rarely upgrade as it is quite allot of
work. Luckily
tomcat is excellent and rarely needs upgrading or patching.
Now the question;
Tomcat 4.1.29 seems to insist on added charset to the

a Content-Type has been set using response.setContentType
or similar
(without a charset). Tomcat 5 seems to do something
similar judging from

I think it fails to check if the Content type is a text one

it for any content type, which would appear not to be right IMHO.

remove the insertion of the charset for non text based
Content-Types eg:

JK2 Endpoint cache comment/question
I am curious as to why the endpoint cache for the ajp 1.3 worker is not in shared memory. It seems that if you want to limit the number of connections to tomcat you would want to it across all of apache, not per process. Is there a reason why it is implemented this way? Example: httpd.conf IfModule worker.c StartServers 1 MaxClients 640 MinSpareThreads 5 MaxSpareThreads640 ThreadsPerChild 64 MaxRequestsPerChild 0 To satisfy this configuration, apache would create 10 processes under heavy load. How would I configure a worker in workers2.properties If I wanted to limit the number of threads that this server can use in a particular tomcat instance to 15. ( We have 2 webservers, and we have found through testing that tomcat/java has thrashing issues above 30 threads ) Thanks CONFIDENTIALITY NOTICE - This e-mail transmission, and any documents, files or previous e-mail messages attached to it may contain information that is confidential or legally privileged.

I'm afraid I'm still ignorant in certain areas of Tomcat 4 configuration. I don't know what Tomcat 4 might have that is equivalent to this feature. I believe Tomcat 4 won't allow you to keep your session when going from HTTP to HTTPS and I assume it wouldn't expose the session if trying to do the reverse.

More Admin Application: Service Reloading Question
I am evaluating Tomcat 5.0.14 for use in a ASP Hosting environment. As part of this environment I would need to routinely create (or destroy) virtual hosts. One major showstopper seems to be that if I create a virtual host and click on the Commit Changes, then the service reloads, including all of the virtual hosts, and their associated contexts. Is there some setting I don't see that can affect this restarting behavior? Without the capability to create virtual hosts on the fly, I will have to schedule routine re-starts of the servlet engine. This is really less than optimal. Any ideas would be appreciated. George Sexton MH Software, Inc.

RE: Webapp classloader question.
I too had a problem loading XML libraries under tomcat 4.1. I thought I identified the problem and reported bug 16577. See http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16577 I proposed a simple fix, but alas, Remy Maucherat, thought the delegation model worked as intended and WONTFIXed it. The upshot is that classes with the following package prefixes are loaded by the parent loader: javax, // Java extensions org.xml.sax, // SAX 1 2 org.w3c.dom, // DOM 1 2 org.apache.xerces, // Xerces 1 2 org.apache.xalan // Xalan As xalan and xerces are in this list (taken from the source code), you can't load your own version of these libraries without modifying the source. -Babak --- Lee, William [EMAIL PROTECTED] wrote: Hmm...

RE: Webapp classloader question.
But the org.apache classes are not endorsed, only the org.xml.sax and org.w3c.dom. These packages contain mostly interfaces and while the implemenation of the JDK comes with the org.apache classes I do not believe these are considered part of the J2SE platform API. JAXP comes with a specific override mechanism such that if a JAXP implementation is found on the classpath that one can be used ahead of any other implementation. Otherwise developers would be stuck with the JAXP parser in the JRE. This means that a parser in mywebapp/web-inf/lib should be used ahead of any other provided you are using SAXParserFactory/DocumentBuilderFactory to load the parser. At least this is my reading of the JAXP specification and certainly the behaviour I've seen running XML apps from the command line and making sure that I have Xerces/Xalan on the classpath for the application. BTW I'm butting in here assuming I know the whole thread, and this is also a subject dear to my heart as I've had so many go arounds of this on so many different Tomcat versions.

Classloading question
Hello, I've asked in the user list before, but nobody seemed to know there. Is it possible at all to use classes from a different context? The crossContext attribute does not seem to enable this. Basically, I have two WARs and want to access classes that are in one WAR from the other WAR (has JSP pages). I know that I could put the classes in the shared/common directory, but these classes are updated frequently and I can't restart Tomcat every time one of them changes. So I'd prefer to have those classes in a WAR and have my other WARs access them. Or is there another way (except via WAR files) to deploy and undeploy specific classes while Tomcat is running?

question on dynamically loaded realms
Sorry if this question should not posted on this list. This is just a question about the design of TC on how to handle different realms. I'm looking at the way realms are handled in TC. I'd like to know why realms have to be registered (for lack of better word) with MBeanFactory, and have to be manually created in there? By looking at the way this is done it can be easily factored out into deployment descriptor files. That way, customized realms (which are still derived from RealmBase as they are right now) can be added much more easily. Is there any plan for this?

Design question about implementing a session manager.
I am implementing a JdbcSessionManager for dealing with non-sticky clusters. We wish to use the DB to store all of our session data when it is not in use. Thanks to Craig's help I was able to figure out how to do the updating of the session data in an InstanceEventListener that catches the AFTER_SERVICE_EVENT. In talking to Filip Hank about his Clustered session manager I was also able to do the database updates in a valve. Which way is preferable? In the InstanceEvent I can just filter out all queries that make this true: default.equals(event.getServlet().getServletConfig().getServletName()) . Filip used the file extensions to create an exclusion list. Other notes: I have had to create my own JdbcSession object instead of subclassing StandardSession because the attributes HashMap is private and I need access to it. (I think) I am serializing the HashMap and storing only that in its own column. My other columns are expire_time, creation_time, app_name, and session_id. I am currently limited to sessions with 8k of data because of the DB limits on VARBINARY but that can change at a later date. --Angus Mezick - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Apache Tomcat 4.1.24 logging question
Howdy, First of all, forgive me if this is trivial, but investigating the source, and various web resources, I was not capable to find the answer, so I hope you can help me. Did you read the Logger configuration reference in the tomcat 4.1 docs? I saw that Tomcat has a different log for each deployed web application. That's one possible configuration, but not the default, and certainly not necessary. And I also saw that there is a log (example: localhost_log.2003-06-14.txt) that is the server log. Again, that's one possible configuration, happens to be the default, and not required. It is a common configuration in production for the administrator to define a Logger for each webapp, and not a logger at the server level. I wrote a class that does some stuff, I jarred it and I've put it in the endorsed directory. It is important, for me, that this class is loaded from that directory (it is not relevant, for the sake of my question, to tell you why; just take it as a must). OK -- but there had better be a very good reason ;) Many server administrators would not add someone else's code to an endorsed codebase. Well, how can I do to write to the server log from within that class ? Depends how your Loggers are configured. Using swallowOutput and System.out is also an option, as Senor Nielsen mentioned. More precisely, which import and APIs must I use? Since you're in the endorsed classloader, you can't use the Servlet API. That would be the better implementation, but anyways you're using the endorsed classloader, so your solution is non-portable. Consider: Server theServer = Server.getServer(); Service theService = theServer.findService(Standalone); Container theContainer = theService.getContainer(); Logger theLogger = theContainer.getLogger(); Now you can use theLogger's log(...) methods. All the above classes are in the org.apache.catalina package. The service name depends on your configuration: Standalone is the default. theLogger may be null if you don't have one defined at that container level. In that case, you can drill down in the code to the Host and Connectors. Note that none of this is recommended practice. The Logger classes may go away or change drastically in future releases. The above code may break in future releases.

Since all cluster nodes have the same state, it doesn't matter where the load balancer redirects it. so you could have sticky session load balancing, or a per request round robin. Once we do more efficient clustering ie primary and secondary state holders, then we need to coordinate a way to load balance around that.

A tomcat SSL question
I am aware that this might better fit in the tomcat-user list. But I have been asking over there for a couple of days, and nobody seems to have an answer to it. Probably it is too difficult? I doubt. Anyway, I hope that I can get some help from here. I know how to use keytool to generate a self-signed certificate and run Tomcat with SSL. I want to use a certificate that is generated by my little Java program which is part of my Certification Authority. So I have my little Java program generate a X509 Certificate called cert4ca.cer. Then I deleteed the tomcat certificate in my keystore and successfully imported cert4ca.cer into my keystore as alias tomcat. See the attached file cert4ca.cer. It's a valid one, otherwise, I would not have been able to import it into my keystore. Now I launch tomcat, but I can only visit http://localhost, not https://localhost. If I reverse to the keytool-generated certificate, both http and https work perfect again. So, would you please give me a hint, how can I use the certificate generated by my little Java program to run tomcat with SSL? Thanks a lot in advance.

A question
Hello All, I am using SOAP 2.2 with TOMCAT 4.1. I encountered the following problem: My SOAP server and my GUI JSPs are installed on the same TOMCAT server (same JVM). Now, everything goes on just fine. I am using the GUI which makes a lot of SOAP calls to the SOAP server. Everything is fine until I leave the system for a few days (the weekend). When I came back I saw that I can't connect to my GUI anymore. What I get is the following error: Action GetList has failed. Details: Error opening socket: Connection timed out: connect at A few more interesting points: 1.When I try to call the SOAP server using a command line client I have everything is fine. I get good results. 2.I make the SOAP calls using a SOAP client class I wrote. In the JSPs I have the client class as a bean: jsp:useBean id=om class=com.mercado.s2002.management.ssoap.MngSoapClient scope=application/. Maybe this has something to do with the failure. 3.When I tried to write a JSP with a single line that open a socket to the SOAP server URL I got the same error. I thought that this has something to do with the fact the system was idle for hours but when I scheduled the system to run every 30 minutes for a few days I got the same exception after about 20 hours. Do you have any idea? This is a critical issue for me, every idea can help. Thank you very much, David - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Something like MODELER_2_0_alpha (I'm not good for name) will be helpfull. Also, is this module supposed to build by itself? Right now the build.xml has a dependency on jakarta-commons. Bundling Tomcat 5 source creates huge zip file (50mg) mostly due to jakarta-commons source dependency. If the dependency is not required, I would be happy to help fixing the build.xml.. It wouldn't be bad if the source zip would include the commons code that we use - modeler, logging, digester, beanutils, collections. But you can fix it to include only tomcat-specific code, since commons has its own src distribution. I don't know if you follow the discussion on the repository - it'll probably affect us a lot. If things settle down and an agreement is reached - we should modify our build acordingly. That may mean we'll have to include version numbers in jars ( if this is voted ), start downloading and uploading to the repository, etc. Probably the some of the download script could be replaced with ruper or some other task ( I hope Ant1.6 will include such a thing by default ). Regarding the tag - I think it would be a good idea to tag it with each milestone of tomcat5.

Hi, I noticed that both org.apache.catalina.connector.RequestBase and org.apache.catalina.connector.HttpRequestBase both have a secure instance variable and the setSecure(bool) isSecure() methods. Does anybody know the reason for this? Thanks, John
DataSourceRealm -- test case (question to Glenn Nielsen)
Hello list, especially Glenn! I'm not sure if this list is the right place to ask this kind of questions, and ask them directly to one person, but I thought that writing straight to such a busy person like Glenn would be even worse. As I saw in sources, you are the author of DataSourceRealm class, am I right? Can you provide me with some test cases about how to configure this realm? I tried to start using DataSourceRealm for about a four days, but still have no luck -- I end up at NameNotFoundException Name java: is not bound in this Context. I tried various places in server.xml to place Resource and ResourceParams tags... Looking at the sources, I found that resource should be placed inside GlobalNamingResource tag, but this didn't help either. Tomcat Users List didn't help me much, may be because nobody have tried this kind of realm yet. BTW, another person in tomcat-user asked for something similar, so this information will be useful not for me only. If you will be so kind to shed some light at this problem, please answer me directly or write in tomcat-user list so anybody who need it will be happy. :-) *** Sorry again, if i broke this list's netiquette. -- Veniamin Fichin [EMAIL PROTECTED] Programmer athttp://www.rbcsoft.ru/ -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

[QUESTION]: CoyoteWriter in error, never cleaned up - NEW RELEASE/FIX

I'm using a rather complicated web page with two frames and

The upper frame has an applet, and the applet loads a

Clicking within the applet will cause new pages to load in the
lower page.
As a result of all this activity I seem to get the Socket Error
bug described in thread Problem with Socket closing and
bug#12810.
Things would still not be too bad if the CoyoteWriter objects
were recycled. When the socket error occurs, the relevant
CoyoteWriter objects get marked as being in error.
The problem is Tomcat (4.1.17 16) is still trying to reuse
these CoyoteWriter objects with the result of tomcat
returning blank pages to the browser.
CoyoteWriter does have a isError() method. A grep through
the source reveals nothing is ever calling this method.
It seems reasonable that after a socket write error, these
objects should get cleaned up and the application would
have a reasonable chance to recover.
Yes, this is correct (and a major bug, expect a new release soon).
There is no problem with recycling after an error. OTOH, the writer must
not be set to a non error state right away once an IOException occurred.
I appreciate any insight and feedback on where these
CoyoteWriter objects should be managed.

question on client authentication by tomcat
Hi, Context: I have a client who comes in to the server with a request URL of the form https://username:password@server/servletname. I need to get this authentication information passed on from apache to tomcat where in my serlvet can strip the userid and password for verfication (using my own mechanism). Authorization headers are returning null values in my current implementation. Question: I read about Custom realms in tomcat. Is it possible to use the same to solve the issue above? If so, how can I derive my own realm classes from RealmBase class to achieve this? I cannot use JDBC/JNDI/Memory realms due to architectural issues and will need a custom implementation. Is there any other way of authenticating such clients (the number of different users and passwords are as high as 5000 and upwards)? Thanks and Regards, Sunu

Subject: Realm implementation question
Please forgive me if this is an obvious newbie question, but I am
not a Java
guru, nor have I studied all the intricacies of Tomcat.
I am trying to implement a new Realm, which will obviously require some
configuration parameters in server.xml, and I want to make sure I
understand
how to access those config parameters from within my implementation.
I can see that o.a.c.Catalina.java creates an
o.a.commons.digester.Digester
that parses the server.xml file. Is it the case that the Digester will
instantiate a Realm object of the type specfied in the className attribute
of the Realm tag in the server.xml file, and initialize that object's
members using the Realm tag's attributes of the same name? So
all I need
to do is write my Realm implementation with accessors and
mutators for each
Realm tag attribute?
So a Realm config that looks like this:
Realm class=org.apache.catalina.realm.MyRealm propOne=foo /
would require a Realm implementation like so:
String propOne = null;
public String getPropOne() {
return this.propOne;
}
public void setPropOne(String prop) {
this.propOne = prop;
}
Am I missing anything?
Thanks in advance,
Chris

Re: 4.1.12 JSPC question
Here is a bit more information. I took a look at the jar files for jsp 1.1 tags and they include a taglib.tld file in meta-inf/. Once I remove that, it compiles the pages fine. It looks like there's a conflict in either jasper compiler or jspc that is unable to resolve which .tld file to use. peter lin peter lin wrote: after a lot of digging, I tracked part of the problem down to jakarta string taglib. once I removed that from my file, it correctly compiles the jsp page.

Cache question
Hello all. Cache question. I have a jsp form that is being forward from a login page that is doing validation from a database. The jsp form has buttons and a click on each specific button will set a hidden input a specific value and and the action will go to another jsp page, where depending on what the hidden input was set to , will jsp forward to the page that is requested. But on click a javascript back, INPUT TYPE=button VALUE=Cancel onClick=javascript:history.go(-1)or the browser back button we get the previous page, but a click on any different button will go to the page you were just at, not the page it should go to. I have http 1.1 configured on my tomcat and I know that if on the page where the buttons reside, I add this : % //HTTP 1.1 response.setHeader(Cache-Control,no-cache); //HTTP 1.0 //response.setHeader(Pragma,no-cache); //prevents caching at the proxy server //response.setDateHeader (Expires, 0);% Then if I click on let say button a to go to a.jsp and click back , I get this: 'Warning: Page has Expired The page you requested was created using information you submitted in a form.

RE: Question about Internationalization
Hi, I tested a GB2312-based JSP page on Tomcat 4.1.12, and it worked fine. (The attached file). It shows ni-hao-ma in simplified Chinese character system and the response encoding, i.e. GB2312. The key point I'd like to make clear is that encoding of a JSP page should keep up with that of response that the page generates for the best delivery of content, in particular, under non-latin-1 character sets. This concept is actually introduced to JSP 2.0 spec explicitly with JSP configuration feature. I believe localization issues will be smoothly gone with Tomcat 5 and other containers compliant with JSP 2 style. P.S. a tech-tip for page encoding: Dreamweaver helps adjust page encoding to a specific character set, such as EUC-KR, and certainly GB2312.

Jasper used to mark the begin and end points in the original source in the java translation as comments in the form: // HTML // begin [file=/index.jsp;from=(0,0);to=(4,0)] Restoring that ability would be somewhat difficult as the parser doesn't track the endpoints of the nodes, just the starts.

Lenny, disclaimer: I don't use JSP's myself so I might be totally off here... but there is the following comment in Tomcat 4.1 Release Notes: -- Using Jasper 1 with Tomcat 4.1: -- It is possible to use Jasper 1 (included in Tomcat 4.0.x) with Tomcat 4.1, as it has the same API and supports the same JSP API. To use Jasper 1 instead of Jasper 2, copy the two following JARs to $CATALINA_HOME/common/lib (overwriting the two existing JARs): * $TOMCAT40_HOME/lib/jasper-runtime.jar * $TOMCAT40_HOME/lib/jasper-compiler.jar However, users are urged to use the version of Jasper included with Tomcat 4.1 (Jasper 2), as it has much higher performance and scalability than Jasper 1. would switching back to Jasper 1 help?

As for Tomcat 4.1.x support, I'm afraid we are out-of-luck here. Tomcat 4.0.4 used to generate useful comments in the servlet code, that allowed the integration plugin to map jsp line numbers to servlet line numbers. But from the new version of Tomcat (Jasper2 in particular), this functionality is missing. At least I haven't been able to find anything to enable comment generation, and nobody from Tomcat user-list answered my question about this. for myself .. all I want to know .. is if this 'situation' in jasper2 will be fixed .. if so .. when .. if not .. why .. we use JSP here .. as do quite a few others .. in quite a few places .. i did not post this question to find out that the developers of JSP (jasper) would rather I use something else .. could this possibly be how the 'managers' of this development effort feel ?? -Original Message- From: Bojan Smojver [mailto:[EMAIL PROTECTED]] Sent: Thursday, September 19, 2002 3:25 PM To: Tomcat Dev List Subject: RE: Jasper 2 Question On Fri, 2002-09-20 at 04:30, Lenny Karpel wrote: is it right that when I ask a serious question about jasper2 that I get these totally ridiculous answers ? Well, Jon and Pier are known to throw in a curly one from time to time, which keeps all of us here on the list in good spirits ;-) Anyway, there is a serious side to all this as JSP's are inherently evil. You'll find that creating true MVC applications in Velocity is almost trivial. I suggest you do read Jon's article. The fact that JSP's are official, doesn't mean they are good.
