Re: mod rewrite, RequestDispatcher and intercepting requests to the server
--- Michael Tickle [EMAIL PROTECTED] wrote: I am attempting to intercept all requests to a server so I can extract information from the header. I would then like to pass the request on to the server for it to display the user the requested page. Sounds straightforward. I am led to believe that TomCat can not direct all requests to it on to a servlet - is this correct? Uh? What exactly are you trying to say here? If you are saying that tomcat can not be configured to send every single request all to the same servlet, then I'm not sure that's true. Couldn't you setup servlet pattern-mapping like so: servlet-mapping servlet-name DelagatorServlet /servlet-name url-pattern / /url-pattern /servlet-mapping servlet-mapping servlet-name DelagatorServlet /servlet-name url-pattern * /url-pattern /servlet-mapping You may need a couple of other patterns like "/*.*" or "/*/*" as I'm not sure of the exact behavior of the wild-card algorithm used in TC. You may also want to define your own context for "webapps/" to intercept activity there from going to webapps/ROOT instead of to your application context. I won't claim that this is simpler or better than just using Apache's rewrite module. It is recommended you use apache anyway for serving static content, so it may be simplest to just settup some RewriteRules to do this (funnel all requests to a single servlet). I have installed apache and using mod rewrite all requests are forwarded on to my servlet. The servlet the extracts the header information. The problem then is showing the user the requested page. Ideally I would just like to return the request to the server and let it deal with it. I am told the closest to this is RequestDispatcher. However RequestDispatcher seems only to be able to use relative linking - this will not work for me as I want to go from http://win2k:9090/servlet/myservlet?To=/index.html to http://win2k/index.htm Firstly is there a better way of doing what I am trying to do? You want to use the HttpServletResponse.sendRedirect() method instead of RequestDispatcher.forward(). The forward() method only accesses urls reachable in the current servlet engine thus they must be relative URLs or 'absolute' relative to the current servlet context path. The sendRedirect() method is an actual HTTP redirect that tells the browser to go somewhere else. Keep in mind that neither a forward() or a sendRedirect() will work once the response has been committed, which can happen if you modify request headers or write more output to the response than the buffer size (8k I believe). Secondly is there a similar feature to RequestDispatcher that can use full URLs not relative URIs? HttpServletResponse.sendRedirect() Thirdly has TomCat got any rewrite functionality (CF mod rewrite) since if I can not pass the request back to the apache domain I will have to somehow rewrite all the URLs in the tomcat domain. TOmcat has pretty minimal rewrite capability (basically the servlet-naming tag above). This sounds like a prime candidate for an Interceptor for a future version (ideally it work consistently with apache mod_rewrite rules in effect) but is not trivial and probably won't happen real soon. However, as indicated above, you should be able to solve your problem by using sendRedirect() to send the requests back to apache (or wherever). Cheers, Mel __ Do You Yahoo!?

I am currently using apache to sent all requests to

page the user requested.
That needs to have some more 'smarts' added to it.
I just tried
response.sendRedirect("http://win2k/index.html");
but that does not work with my rewrite rule as the

to the servlet.
Of course it won't! Your rewrite rule is immediately
forwarding it 'back' to the servlet! :-)
1) request comes to apache
2) your rewrite rule sends it to tomcat servlet
3) tomcat servlet redirects it to apache
4) repeat at (2) !!!
You need to put some clue to the Rewrite Engine to
tell it that you don't want a URL to be rewritten
further.
I would suggest that you preprocess the url in your
servlet before you do the sendRedirect to embed some
clue such as rewriting it as:
http://win2k/index.html -
http://win2k/index.html?DELEGATED=true
or whatever. Next, modify your rewrite rule to have a
conditional:
RewriteCond $0 !.*/DELEGATED.*
RewriteRule ^(.*)/(.*)
http://win2k:9090/servlet/redirect?To=/$2 [R,L]
This will make your rule skip any URL with the 'clue'
you've embedded.
Next, apply a rule to remove the 'clue'
RewriteCond $0 .*/DELEGATED.*
RewriteRule (.*)/DELEGATED(.*) $1$2
don't redirect this time or you'll just jump back into
the cycle.
Alternatively, you might just add a query string param
or set some other request info to act as your 'clue'.
Still another alternative is to simply run another
Apache server instance or virtual host that does NOT
apply your rewrite rule. There are lots of
strategies. Use your imagination. :-)
I was informed that this would not
happen with
RequestDispatcher.
??? RequestDispatcher will only forward or include
requests to be serviced in the same servlet engine.
It can not redirect back to apache.
The other option I can think of is to turn all the
HTML pages in to JSP and
have the JSP collect the information (request page,
referring page, date,
time, user agent and session id) and send it to a
servlet - would that be a
better way of doing it?
It depends on your application. I don't really have a
clear idea on what your high-level goal is here.
Good luck,

Re: help: no stack trace in standard out
--- Jon Crater [EMAIL PROTECTED] wrote:
but i can't get a stack trace printed to the
standard out to save my
life.
any ideas?
Whether or not a stack trace gets printed is not a
function of the logging level. A stack trace will be
printed under the following conditions:
If an uncaught exception makes it through to the VM
runtime, a trace will printed by the runtime to
standard err (System.err).
If a catch() block in your code (or someone else's
code higher up the call chain) catches an exception
and proceeds to explicitely print the stack trace.
Note - if you are throwing an exception that you
expect to show a trace at the runtime level, it is
possible that "someone else's code" is catching it and
ignoring it (a very bad practice but all too common).
Finally, you can always just create a Throwable object
and print the stack trace yourself.
To display the stack trace of a Throwable object to
System.err, you can just use the
Throwable.printStackTrace() method. Thus, in your
code you might put:
try{
// do something that throws a FooException
}catch(FooException e){
e.printStackTrace();
}
Or, for debug purposes to find out how you got to your
code without relying on some Exception being thrown,
just do the following:
//...do stuff...
(new Throwable()).printStackTrace();
//... continue doing other stuff...
The only problem with the above technique is that
there is no control over formatting or where the
message goes. It always goes straight to stderr. To
change that, you can capture the stack trace in a
String using a simple method like so:
/**
utility function for retrieving the stacktrace of
a Throwable object as a String for easy
manipulation.
Useful for debugging. Returns "" if it/i==null.
@param bt/b a Throwable object.
@return a String representation of the stack trace
for it/i.
*/
public static String getStackTrace(Throwable t){
if(t==null){
return "";
}
StringWriter sw = new StringWriter();
t.printStackTrace(new PrintWriter(sw));
return sw.toString();
}
Put the above method into a utility class (i.e.
'MyUtils' and then you can always grab the trace for a
throwable anywhere in your code with:
String trace=MyUtils.getStackTrace(new Throwable());
That way, you can display the trace in an html page,
or search it or make it part of the message nested
inside another exception, or whatever.
Using stack traces like this is a very useful tool for
developing and debugging code, or for simply trying to
understand other folk's code. Visual Debuggers are
useful too, but less reliable and not ubiquitous.
One tip: You refer to wanting to print the trace to
'standard out'. Just a bit of developer's philosophy,
but:
Standard out - for program _output_ (i.e., the actual
product of the application). Example: 'more'
displays text from files to stdout.
Standard err - for program _debug_ and _error_
messages. Example, if 'more' can't find the file
indicated, it prints an error message to stderr.
The distinction is important because conceptually,
these are two different io streams. By default,
System.err prints to the same OutputStream as
System.out, but that is not necessarily always so.
You can easily redirect one or the other using
System.setErr() or System.setOut(). By always sending
your debug and error messages to System.err, you
should not have to worry about forgetting to remove
all your debug statements and accidentally corrupting
your program's output.
Just my $.02. Take it for what it's worth. :-)
I hope this is helpful.

in the code already where folks have improperly
assumed they can use "/" as the file separator. So
watch out for possible problems in that area (mac OS 9
uses ':', mac OS X can use either ':' or '/').
Rule of thumb: When building file paths, be sure to
either use either the system property
System.getProperty("file.separator") or the public
field java.io.File.separator as the separator.
Alternatively, you should just let the File object
build paths for you:
String base = "/some/path"; // arbitrary '/' here
String dname = "mydir";
String fname = "myFile.txt";
File f = new File(base);
f = new File(f,dname);
f = new File(f,fname);
The above would build "/some/path/mydir/myFile.txt" on
unix. On a mac (assuming base=":some:path", the
result would be ":some:path:mydir:myFile.txt"
2. Download Darwin, Apache for Darwin and Tomcat.sit

If you want to run Apache, you will need to use Darwin

If you don't need Apache, then tomcat itself should
run fine on Mac OS 9. MRJ 2.2.4 has many 'Java 2'

3. Purchase SuSE 7.0 for PPC?

Re: TC3.2.1 - response commit on included JSPs
--- Incze Lajos [EMAIL PROTECTED] wrote:
Maybe it's not correct in general but the JSP 1.1
syntax
contains the flush="true" attribute - obligatory in
case
of jsp:include. So, it's inconvenient but tomcat3 is
an
jsp 1.1 implementation. Am I missing something?
incze
The JSP 1.1 spec says that the current response buffer
should be flushed _prior_ to the inclusion. In other
words, the flush="true" requirement is talking about
what should happen at level of the calling page. In
normal java servlet code this is saying :
if(buffered flush==true){ //JSP1.1 flush always
true
out.flush();
}
requestDispatcher.include(...);
//continue...
All this is saying is that, at least for JSP 1.1, we
are required to write everything we've put in the
buffer now before we add more to the buffer from the
included resource. This requirement is supposed to
happen on the CALLING page, not in the INCLUDED page.
I will note that TC3.2.1 does not actually do this
correctly and if it tried, it would break because of
the same root cause to the problem I am talking about
here.
The problem I am talking about is independent of the
_calling_ page.
The problem is caused by the nature of the JSP servlet
that is generated by TC3.2.1. It cannot properly be
included (dynamically) from either a JSP *OR* a
servlet because when it exits, it always sets the
isCommitted() flag of the response. It should not do
that if the page is processing a request as an
'include' action because only the parent, calling
servlet or jsp should Commit the response.
As explained, the reason it always sets the
isCommitted() state is due to the sequence:
1) Every JSP page generated by TC3.2.1 has a finally{}
block that invokes out.flush() and...
2) For some reason the TC 3.2.1 JspWriterImpl
implementation of out.flush() commits the response
even BEFORE it calls response.flushBuffer()!
3) Also, out.flush() ALWAYS calls
response.flushBuffer() even if processing an included
request.
IMHO out.flush() should not commit the response. Only
response.flushBuffer() should commit the response.
And response.flushBuffer() should not be called from
an inside an 'include' request.
What probably SHOULD happen is the following:
1) Response.flushBuffer() alone should be used to set
the commit state. But it should NEVER be called from
within an include action which can be checked with:
Obj incl = request.getAttribute(
"javax.servlet.include.servlet_path");
if(incl==null){
response.flushBuffer();
}
2) It is probably fine for out.flush() to be called at
the end of every JSP page. Optionally, a check like
in
(1) could be used to call response.flushBuffer().
3) MOST IMPORTANTLY - JspWriterImpl needs to be
rewritten so as to flush the output stream, but NOT to
commit the response and NOT to call
response.flushBuffer()!
I'd say that I consider this a serious bug because it
makes it impossible for a JSP page to be included in
any other JSP or even a Java Servlet except as the
last committment to the response - which means that it
is essentially only a 'forward' action.
Also, the fact that out.flush() (incorrectly) commits
the response actually means that technically TC3.2.1
can not be made compliant with the very spec you cite
because if it DID enforce the flush="true" attribute
and then tried to include a resource (or do ANY output
or forward or redirect), an error would occur becuase
(as I've stated) the response would already be
committed as soon as out.flush() got called.
"Fortunately", tc3.2.1 is currently broken in this
regard and is NOT actually flushing the output before
the include. If the above problem in out.flush() is
fixed, then this should be fixed as well.
This bug has thrown a HUGE wrench into my current
project and I'm not sure how I'm going to address it
in the short term.
Hasn't someone noticed this before? Is this problem
fixed in either of the later versions (3.3 or 4.0)?
If so, I may need to upgrade and I really hate having
to upgrade to non-release versions of software since
that entails a whole lot of risk/justification I have
to explain to my clients.
Sigh... if it ain't one thing, it's another...

Yes, by 'dynamic' include (the above) I was making the distinction from a 'static' include, which would be done with the syntax %@ include file="blah.txt" %. The problem with the TC3.2.1 behavior is that after performing a dynamic include (using any of the above three methods), of a _JSP_ resource (served by TC3.2.1), the response will be committed. Note that if you do a dynamic include of some other resource (such as a servlet) the response would not necessarily be committed (and generally shouldn't be unless a forward or redirect occurs).

Re: POST Method
I'm encountering a slightly different problem with
POST.
I'm using tc3.2.1 and apache 1.3.17 on win32 for dev
purposes (we haven't yet setup the linux boxes that
will be used for production).
When send a request from a form method=POST... to
tomcat via Apache, it gets invoked okay, but the
parameters of the form don't get there! That is, when
I print out the results of request.getParameters() it
is empty.
If I send the request directly to tomcat, it works
fine. If I send the request using GET instead of
POST, via either Apache or Tomcat, then it works fine.
I am wondering if the problem I'm having is due to the
use of a RewriteRule that uses [R] to redirect the
request? Does a Rewrite/[R] cause a problem for a
POST request?
In your example below that 'worked', did you try
printing out the result of the request.getParameters()
call?

tell us what you are trying to do and send us some

easier than to answer the
question above, because alias works very well for me
:)
Well, actually, I've twice posted detailed
descriptions of what I'm trying to accomplish on this
topic and gotten zero replies, but here goes another
attempt...
I'm using Apache 1.3.14 and tomcat 3.2.1 with
mod_jk.c. I don't know if the latter is the 'latest'
version of mod_jk.c - I grabbed it from the tomcat
download site two weeks ago. I am running this on
WinNT using downloaded binary versions of the relevant
software.
I have setup my application ("myapp") as a directory
inside the webapps/ directory, complete with WEB-INF
subdirectory and such.
I have apache configured to apply an alias or a
rewrite rule to a reqest:
#--
IfModule !mod_rewrite.c
LoadModule rewrite_module
n:/opt/local/apache/modules/ApacheModuleRewrite.dll
/IfModule
RewriteEngine On
RewriteLog log/apache_logs/rewrites.log
RewriteLogLevel 9
RewriteOptions inherit
RewriteRule ^/myapp/(.*)/common/(.*) /myapp/common/$2
#-
I can tell from the rewrites.log that it is indeed
getting applied:
(2) init rewrite engine with requested uri
/myapp/folder1/common/mypage.jsp
(3) applying pattern '^/myapp/(.*)/common/(.*)' to
uri '/myapp/folder1/common/mypage.jsp'
(2) rewrite /myapp/folder1/common/mypage.jsp -
/myapp/common/mypage.jsp
(2) local path result: /myapp/common/mypage.jsp
(1) go-ahead with /myapp/common/mypage.jsp [OK]
The idea here is simple: the request
/myapp/folder1/common/mypage.jsp
should result in a request for
/myapp/common/mypage.jsp
The rewrite rule works great. This works great for
static stuff (i.e. html) served up by Apache.
The *problem* is that Tomcat is not getting the
translated request, it is getting the original one:
/myapp/folder1/common/mypage.jsp
Since no file in that path actually exists, naturally
it returns a file not found error. Tomcat DOES
happily find, compile and execute requests for
servlets and jsp pages that are in paths that do exist
such as
/myapp/folder1/myother.jsp
I have apache configured to send requests to tomcat
via ajp13 by including mod_jk.conf-auto just after the
above rewrite rule:
# include configuration for tomcat servlet engine:
#
Include n:/opt/demo/conf/mod_jk.conf-auto
#
I've configured server.xml very minimally, no custom
contexts or anything. About the only thing changed
here is I've enabled ajp13 and then setup
workers.properties to map requests to it. I doubt any
of this is relevant because I see the exact same
behavior even with 'raw' server.xml and
worker.properties files.
Note that I get the same behavior if I use an Alias
instead of a rewrite:
#--
Alias (.*)/myapp/(.*)/common/(.*) $1/myapp/common/$3
#--
This rewrites static requests served by Apache, but
just like with rewrites, gets ignored by tomcat.
That's pretty much it.
Any suggestions as to what is (or is not) going on?
Basically, what I want to happen is that, after a
rewrite rule has been applied, that Tomcat should be
processing the modified URL, not the original.
Thanks in advance for any help!

Re: mod_vhost_alias.c
After downloading Apache 1.3.17, and wasting most of the last few g*d*mn hours trying to get an update of the Windows MSI installer tool just so I could install the new apache, I must unfortunately report that for all I can tell, mod_vhost_alias is still NOT included with the standard Win32 binary distribution. The new version does change the name of the modules in the modules/ folder from the form: ApacheModule.dll to the mod_xxx.so form more consistent with unix distributions. Strangely, no one bothered to update the httpd.conf file that comes with the distribution to reflect this change. I also was left more than a little annoyed by the fact that the 1.3.17 installer automatically installs apache as an NT service and starts it - without an option for me to avoid this 'feature'.Basically, this release could use some polish. At any rate, I guess I am left with assumption that there is no version of mod_vhost_alias available for the win32 version of apache. Hopefully someone will pop-up with a correction to that.

ajp12 vs ajp13 mod_jk.conf-auto
Question: what determines whether ajp12 or ajp13 will be specified for a jkmount statement in the auto-generated mod_jk.conf-auto file? I.E., it always generates statements like: JkMount /myapp/servlet/* ajp12 JkMount /myapp/*.jsp ajp12 I've even tried disabling all reference to ajp12 from server.xml and workers.properties but that had no effect. Is the only way to force the use of Ajp13 to manually edit the mod_jk.conf file? Should I even be worrying about this? Thanks, mel __ Do You Yahoo!? Get personalized email addresses from Yahoo!

Re: ajp12 vs ajp13 mod_jk.conf-auto
Thanks, Filip. I'll try the changes you suggested. Now, if I could just get someone to tell me why apache Alias and Rewrites are not working with tomcat... Mel --- Filip Hanik [EMAIL PROTECTED] wrote: yes, the JkMount command looks like this JkMount context workername so the autogenerated ajp12 is just the worker name "ajp12" in the workers.properties file you can change the protocol that the worker is using. the property file has the following format worker.workername.propertyname=value worker.ajp12.port=8007 worker.ajp12.host=localhost worker.ajp12.type=ajp13 so just change the last line to use ajp13. now you have to modify server.xml to start a ajp13 connector on the port 8007 and change the port for ajp12. the nice thing with the autogenerated file is that your webapps can be dynamic. but if you need to do a lot of fancy stuff, you should create your own file for the mod_jk configuration. try playing around with it, and if you have a specific problem let me know and I can help you out.

apache AliasRewrites vs tomcat?
I'm trying to assertain just how Apache and Tomcat interact regarding aliases and rewrites. I'm using Apache 1.3.14 and tomcat 3.2.1 with mod_jk.c. I don't know if the latter is the 'latest' version. If I have apache configured to apply an alias or a rewrite rule to a reqest, I can tell from the logs that it is indeed getting applied: (2) init rewrite engine with requested uri /myapp/folder1/common/mypage.jsp (3) applying pattern '^/myapp/(.*)/common/(.*)' to uri '/myapp/folder1/common/mypage.jsp' (2) rewrite /myapp/folder1/common/mypage.jsp - /myapp/common/mypage.jsp (2) local path result: /myapp/common/mypage.jsp (1) go-ahead with /myapp/common/mypage.jsp [OK] The idea here is simple: the request /myapp/folder1/common/mypage.jsp should result in a request for /myapp/common/mypage.jsp The rewrite rule works great. This works great for static stuff served up by Apache. The problem is that Tomcat is not getting the translated request, it is getting the original one. Since no file in that path actually exists, naturally it returns a file not found error. Could someone please tell me if this behavior is correct or if this is a bug in mod_jk? Should I be using apj13? (I just noticed that the mod_jk.conf-auto has the contexts mounted to apj12 so I'll try changing that). I seem to recall that JServ obeyed the results of rewrites. Should I try using tomcat with mod_jserv? 'Would seem like walking backwards... Please help clear this up so I don't spend too much more time banging my head against this.

Apache + tomcat: help w/mod_alias
Hi, First off, I'm using Apache 1.3.14 (win NT and linux) and tomcat 3.2.1. If I need to upgrade I will, if I know that it will fix this. I'm trying to setup tomcat with an existing apache web server. I'm having trouble figuring out the best way to handle an otherwise simple Alias mapping. The apache httpd.conf has the following: Alias .*/foo/(.*) /abs/path/to/foo/$1 which basically says: treat all paths with '/foo/' in them to be a link to the one great and powerful foo directory. So both of the following: .../somepath/foo/splash.html .../someotherpath/foo/splash.html would both map to the same file, /abs/path/to/foo/splash.html This is very useful for having links to a common directory of reusable resources from a variety of locations. In addition, this works on both Unix and NT versions of Apache so you don't have to depend on symbolic links. On top of Apache, I've added the use of Tomcat to the mix so as to (naturally) support servlets and *.jsp applications. I have done this through the use of mod_jk. So far, Tomcat works just fine for running servlets and compiling JSP files. With the following exception. Problem: Urls forwarded to tomcat seem to bypass the Alias mechanism. So a request for: .../somepath/foo/myapp.jsp gets sent to tomcat as the above, instead of as the desired: /abs/path/to/foo/myapp.jsp Since there is no 'foo' directory inside /somepath/, tomcat complains about not finding the file. Naturally, if I turn off mod_jk, so that Apache simply returns the file, apache finds the myapp.jsp file just fine. Could someone offer me some helpful suggestions on the best way to fix this? Would this be fixed if I replaced the alias with a mod_rewrite directive? Does Tomcat have a comparable 'alias' or 'rewrite' mechanism? Is this a matter of setting up things with the proper precedence so that the Alias gets applied to the URL before it gets sent to the mod_jk worker? If so, how? Thanks in advance for your help.
