mod_jk 1.2.8 socket_timeout property on solaris 2.8 - doesn't work

[Java Developer]

We have mod_jk 1.2.8 with apache 2.0.53 on solaris 2.8 connecting to JBoss 
4.0.2 on solaris 2.8.


The number of apache child processes grows gradaully and upon reaching 
around 150 the system response degrades forcing us to restart the apache 
server.


On investigation it is found from the mod_jk.log that a apache child process 
serving a user request does not get reponse from tomcat[jboss] and so it 
waits for 2 hours and retries 3 times. No clue as why it waits for 2 hours 
and where is this configured.

To resolve this thought of using the socket_timeout property setting it to 
worker.abc.socket_timeout=600 i.e., 10 mintues. It works fine for apache 
running on windows but does not work for apache running on Linux/ Solaris.


Any clue as why this property is not working on Linux/ Solaris.

RE: startup script not working

[java]

I don't know about Tomcat 5.5 specifically, but in Tomcat 5.0, startup.bat calls
catalina.bat which calls setclasspath.bat.  You'll see it runs the following,
and if it can't find any of the files (probably because your JAVA_HOME is a JRE
and not a JDK), it'll call "exit" and close your window:

if not exist "%JAVA_HOME%\bin\java.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javaw.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\jdb.exe" goto noJavaHome
if not exist "%JAVA_HOME%\bin\javac.exe" goto noJavaHome

It's kinda hard to see the meaningful error message from this batch file when
the window closes.  I've always wondered if this is a bug?

Re: precompiling jsp files gives error

[java only]

Yes it is there in the classpath...Moreover,when I try to run the build.xml file as 
given in the tomcat docs , it runs fine until it encounters the compile error problem 
because of the included jsp files within jsp files.This was the reason I tried running 
the changed build.xml file (tomcat-precompile-jsp.xml file)  as suggested by one of 
the developers here, but it is giving me build failed as mentioned earlier...
 
Can anybody please help ?

Unable to compile class for JSP

Hi all,
 
I am unable to compile JSP files,it gives me the following exception
 

org.apache.jasper.JasperException: Unable to compile class for JSPNo Java compiler was 
found to compile the generated source for the JSP. This can usually be solved by 
copying manually $JAVA_HOME/lib/tools.jar from the JDK to the common/lib directory of 
the Tomcat server, followed by a Tomcat restart. If using an alternate Java compiler, 
please check its installation and access path.  at

I have even copied the tools.jar from my $JAVA_HOME/lib to $CATALINA_HOME/common/lib , 
but still it gives me the same error.Earlier default javac compiler was used,and 
everything was running fine.since changing my compiler to jspc in /conf/web.xml (so as 
to precompile my jsp files and save the memory leak),I am encountering this problem.

Any input would be sincerely appreciated.

Thanks,

Re: JAVAC Leaking Memory

Is it that JSP pages compile only once(not just for each session) but for the entire

no. It does not mean that. you can set fork option to false, and 
reloadable/developement to true or vice versa, anyway you like. But I 
still recomend that in production environment you set developement to 
false and reloadable to false.

setting fork option to true will throw avay the javac process when it's 
done it's work, leaving no memory leaks, but I think it's a little bit 
slower than fork=false. I'm not sure, maybe someone else can answer that.

Page compilation is only done once for each jsp document. I think your 
session lagging has to do with something else, some session related 
code/rendering etc.

hope it helps

Starting tomcat

[Java User]

Hi,
 
I am newbie for tomcat 5.0.16. I installed tomcat 5.0.16. When I am starting the 
server, the window appears but it closes by itself. I looked at the error and the very 
first error states that:
 
"[ERROR] Digester - -Begin event threw error 
java.lang.ExceptionInInitializerError: 
sun.misc.InvalidJarIndexException: Invalid index!"
 
FYI, I have java version "1.3.0_02" and my JAVA_HOME variable is as follows:
"set JAVA_HOME=D:\jdk1.3.0_02". I did not define CATALINA_HOME variable. It is, I 
guess, defined by the tomcat startup script.

Can somebody help???

I think this is a bug as per the servlet specification.Just check with some

BUG: Tomcat does not reload webapps properly

[Jiger Java]

Hi,
  Am using Tomcat 4.1.12 on Windows 98/Linux. I found that tomcat when 
realoding a webapps becoz a class changed, does not call the Servlets 
registered as LoadOnStartup. Becoz of this the application starts correctly 
but if reloaded without a restart, the application comes unusabled since the 
other servlets/jsp's depend on a lot of stuff initialized in the 
LoadOnStartup Servlet's init() method.

does anyone have any idea if this is fixed in latter versions or work 
around?

Thanks,
Jiger

RE: access to servlets

[Java Group]

If I disable the invoker, I can't access to any of my servlets from the main servlet.

The method is that the user use the name in the mapping to enter the application and 
from there I fw the request to the relevant servlet (kind of dispatcher) and from the 
main servlet I use the original class names and classpath.

Date: Thu, 14 Nov 2002 10:28:57 -0800 (PST)

Hi,

I am attempting to setup tomcat's SSL, but failed.

I am using tomcat 4.1.12, j2sdk1.4.1_01 and Win2K
professional.

Running tomcat without SSL is successful.

Then I followed the instruction of tomcat-ssl-howto
and generated the .keystore file, modified server.xml.

Then when I start tomcat, I get the following severe
handshake error and if do http://localhost:8443 in my
browser, I see nothing except a completely blank page.

Would you gurus please kindly tell me how to fix this?
 Thanks a lot!

Re: How to create a connection pool

[java guru]

Hi -
  I am not sure on what type of application you are
building, but doing connection related stuff
(including running sql over already established
connection in jsp) isnt very good idea. Read about mvc
model if you are in design stage.
   In anycase, if you still need access to pooled
connection, tomcat offers connection pooling (in the
default server.xml ) and refer to apache jsp taglib on
how to access one.

RE: Running tomcat as service

[Java Group]

The Tomcat version I'm running is 4.0.3.
I installed the tomcat as service from the installation options.

The service "log on" is as "local system account".

About the APACHE_HOME\modules there is none like this name in the 
directory. The dll is my dll and it is loaded perfectly if I run the tomcat through 
the start menu and not as service.

During installation did you select to install Tomcat as service, or, are 
you trying to add it after the fact?

Make sure the service "log on" is as "local system account".  Can be found 
on the "log on" tab for the service.  Make sure the .dll is in the 
APACHE_HOME\modules dir, not a link, and the load modules line for apache 
is setup correctly.

Who owns the .dll, and who has rights to it?

serious issues with tomcat and rmi

I am encountering serious issues with tomcat and rmi..
I am getting all sorts of problems ranging from 

1. version 4.0.3 cannot load classes from rmi
codebase.. reading the codebase but returning
classnotfound exceptions..

2. version 4.0.4 webappclass loader dying with 'Life
cycle error' and access control exceptions on
web-inf/lib even when used with all.policy with most
liberal security settings..

3. And all these different class loaders and
exceptions look very confusing and impossible to make
it work.

Hope someone would throw some light..

Re: Tomcat refusing jsessionid's

[Jiger Java]

Philip,
  I did try using url re-writing using jsessionid'd & that is why I 
wrote this mail. TOmcat seems to use jsessionid in cookies first & if not 
there only then take jsessionid from url. This is my guess coz that is what 
is happening.

Does anyone have any idea how to force using jsessionid in such situations 
to make user jump between two domains(though they are in reality same 
machine & same tomcat) without his knowlege.

Tomcat refusing jsessionid's

[Jiger Java]

Hi,
I have checked the archives already but did not come across similar 
problems so I would like to ask it.

My Platform:
Tomcat 4.0.
JDK 1.4
RHT Linux

We have this application hosted on an generic server say 
http://www.server.com now our reseller's can map their DNS such that 
www.reseller.com points to www.server.com this will be dynamic( since 
reseller's will be doing it themselves) so I can't use "virtual host" 
feature of tomcat. The idea is that customer of that reseller should not 
come to know that they are actually buying stuff from us & so the customer 
*always* sees the reseller's website url in his browser. All pages post to 
http://www.reseller.com/customer/xyz , which would post to us due to DNS 
mapping. So far so good. But in many critical places like Login, customer 
signup, we have hardcoded url's to our https:// server (same machine same 
tomcat) becoz reseller need not buy Secure Certificates.
   This is the problem. Inspite of my adding jsessionid to all such 
pages right from posting to https:// to  refreshes, I still can't seem 
to get back the session. Logically, if I pass in the right sessionid, tomcat 
should pick up the correct session but it is still picking up pre-login 
session & refusing the new sessionid got in the Authenticationservlet.

I attach the jsessionid something like this 
http://www.reseller.com:10001/anacreon/servlet/CustomerIndexServlet?jsessionid=A4A0314540585318A4F5E327F1457375

   Does anyone have any idea how to solve it. Please ask me if you need 
more clarifications. I need to get this thing out.

   Thanks & Awaiting your replies,
   Jiger

tomcat connector looking for OLD DEV worker ?

[java guru]

Hi.,
   I am trying tomcat connector (4.0.3) with iplanet
server. After changing workers.properties file, the
connector is still looking for DEV worker. Connector
initialization shows new workers but while serving the
request, the connector returning error as its looking
for old worker.
  
   Is there some kinda 'cache' mechanism here ?

iplanet tomcat connector caches worker names

[java guru]

Hi.,
   I am trying to setup tomcat connector (4.0.3) for
iplanet (6.0 sp2).

   In the intial testing, connector is caching the
worker name previously used (even after
worker.properties changed and iplanet restarted). In
the jk_log, I see the new worker properties taking
effect, but once i try to access url, i see that the
connector is looking for worker that was previously in
effect. This happens even after i clear all cookies
from my browser(thought the sticky session was causing
problems)..

i appreciate response.

Thanks

Url Rewriting in Tomcat4.0

[Jiger Java]

Hi,
Is is possible to do url rewriting  in Tomcat. Something such that when 
a request like

http://www.server.com/reseller comes in then the server will
execute/get/map/etc etc & the final url will become as
http://server.com/servlet/LoginServlet?role=reseller
which is then the named servlet be executed. The  allows 
only Servlet Class file name & alias but not alias with params. Can we do so 
in Tomcat 4.0.

Thanks & Awaiting your replies,
Jiger

Servlet Mappings Problem

[Jiger Java]

Hi,
   I am having some problem fitting my requirements in web.xml. I want to
do something like this.
Whenever a user says http://server.com/contracts . It is supposed to show
him the login page. But with some extra parameters to be added.
So basically the url will become
http://server.com/anacreon/servlet/AuthenticationServlet?role=reseller

Can I do this using simple Tomcat.(We dont use apache so dont tell me to use
url rewriting stuff).
I am also not in favour of writing servlets that do this & then mapping
the url to this servlet. That is a bad solution. Cant we specify in web.xml
something like this.


   internalauth
   InternalAuthenticationServlet
   

   
   internalauth?role=marketing
   /contracts
   

   
   internalauth?role=finance
   /finance
   


Specifying params in  also gives error.


Any idea would help.

Thanks,
Jiger

   I my case I am NOT loading anything from shared classpath. nor am I 
giving references to them of classes in /WEB-INF/classes or /WEB-INF/lib 
classes. So this is very funny & annoying error.
  If u had read my previous mails, I had described that I was using a 
Utility that I created on the samelines as Struts BeanUtil.populateBean() 
method. Which auto-populates FormBean's from request or Hastables.
It works perfectly well normally, but as soon as I recompile any class 
in my webapp triggering webapp reload, The formbean population fails for 
some methods, so my validate will return false & the app goes into loop 
showing errors highlighted although user has filled in all the required 
details.
   If I still continue, tomcat starts giving me annoying errors like 
ClassCastException, NoClassDefFound, LinkageError and what not.
   I could send u my stacktraces once more if u want.This seems to be a bug 
of how all classes loaded from the same place, then destroyed & Re-created 
start giving problems.

Any idea.

RE: having to restart tomcat for new classes -More

[Jiger Java]

Hi Craig,
  I just wanted to ask why do u have to restart the entire app when 
even one class changes.
   You must have seen my past 3-4 days mails & am to facing a similar 
problem, I am not sure if this is a JDK 1.4 beta3 related problem but 
whenever I recompile any of my class which triggers context restart because 
of which then entire tomcat becomes unstable & I start getting funny error 
like
java.lang.NoClassDefFound : java/lang/ClassCastException

or linkage error & what not. I am FORCED to restart my tomcat server as u 
will agree this is not possible on a production server.

Can u just explain how can we prevent classloading errors & points to keep 
in mind so that even if entire Context is being restarted does not affect 
our app.

Thanks & Awaiting your reply,
Jiger

Possible bug in Tomcat 4.0 final

[Jiger Java]

Hi all,
   I am using Tomcat 4.0 final, Win98, JDK 1.4 beta 3.

Problem description :I feel that Tomcat is loosing some values from the 
session.

Problem explanation : In the application we are building,I have tomcat 4.0 
final running on win98. In my app the user logs in, & his username,password, 
userid, and Language obj(for multilingual stuff in my app), etc etc are 
stored in this session.
  As he roams the application many different objects arestored in his 
session. Now if I recompile some of my servlets/classes, Tomcat reloads my  
application due to change in class. Since I have one  servlet 
I can see it load. But then a very funny thing happens. The user logged in 
looses some data from his session!! where as some others are left intact.
  I have noticed that all Strings kepts in session are left intact but all 
objects I had kept are removed.
  Can uall tell me if I am missing something or is this a possible bug in 
tomcat.

Awaiting your replies,

Thanking you,
Jiger

Problems with Tomcat4, Reflection & Classloading

[Jiger Java]

Hi all,
  I am using Tomcat 4.0 final, JDK 1.4 beta 3, Win98 for dev.

Double check idiom broken - Tomcat uses it ?

[java programmer]

Hi all:

We all know that the lazy-double-check idiom doesn't
apply to Java because of the Java Memory Model (JMM).

That is to say, look at code such as:

Example a)  
// Set by any other thread other than #1
volatile boolean stop = false;

// Thread #1 runs this as long as
// stop is false. Only T1 will call this
// method, so not synchronized. hence 
// broken due to staleness of 'stop'.
// synch for _visbility_ ALSO.
void foo() {
 while (!stop ) {  //... }
}


Example b): The lazy double check idiom
public static Foo haha = null;
public static getFoo() {
if (foo == null ) {
  sychronized (Foo.class) {
 if (foo == null )
foo = new Foo();
  }
}
return foo;
}

Both examples are *guaranteed* to be incorrect. 
Note, this is the case, *even* though I am using
'volatile' for the stop variable. For more on the 
JMM, consult Item #48 in Effective Java (Josh Bloch),
look at Bill Pughs' page at:
http://www.cs.umd.edu/~pugh/java/memoryModel/DoubleCheckedLocking.html
or check out Doug Lea's stuff.
Well, here is the thing:

Quite idly, and randomly, I was looking at:

org.apache.jasper.servlet.JspServlet

and I found:


outDated = compiler.isOutDated();
   if(!jsw.isInstantiated() || outDated ) {
  synchronized(jsw){
outDated = compiler.compile();
if(!jsw.isInstantiated() || outDated) {
if( null ==ctxt.getServletClassName() ) {


This is a complex use of double check type
code and is really hard to analyse because references
themselves and what they point to can have 
different levels of staleness (according to the JMM).
So it's a turbo double idiom type usage, possibly
incorrect.

I just wanted to bring this to the attention of the
development team and make sure that *someone* has
really analysed this according to the JMM. (and
any other code, similar to this).

server.xml - Part II

[java programmer]

First off, I'd like to reply to an earlier post
and the I'll talk about a weird finding 
regarding server.xml with Tomcat 3.3 on Linux 2.4.x
with Java 1.3.x.

> We're the main european hub for bioinformatics
> research and resources,
> the fact that webapps exist and can be packaged is

Hmm. I stand somewhat corrected. I still believe
that the "webapp" complexity is not applicable to
many people, who simply want Apache + an engine
to run servlets/JSP, probably talking to mySQL
in the backend. For that kind of use, you don't
need more than one context, i.e., the default "/"
context hanging off the docroot (htdocs) of 
the *web* *server*.

Again, agreed. However, consider the fact that this
heirarchy is relatively flat, 2-3 levels deep in
most places. Isn't it simpler to use a file of 
the format:

level1.level2.prop1=value
context.foocontext.simplemapper=foo.class
context.foocontext.simplemapper.listings=false
... and so on ...

This approach has a lot of precedent and works
very well (for shallow depths). Also, it's
simpler to have a default case of one config 
file only, with a *special case* option of
more files if needed. Apache does this too for a 
reason. Also why expose the module map at all ?
(modules.xml). Most end-users are not going to
write and swap in their own modules and most
hackers are just going to hack the tomcat source
directly. 

Now for a bit on my environment. I have several
SMP boxes that I am planning to run Tomcat+mySQL
+Apache on. Apache and mySQL are now running quite
smoothly but Tomcat is still not up yet. I keep
getting a funny exception when I say:

shell> tomcat.sh start debug -10

The relevant part of this exception looks like:

---
EmbededTomcat: exception initializing ContextManager
java.lang.NullPointerException
at
org.apache.tomcat.facade.JspInterceptor.addContext(Unknown
Source)
---
After tearing my hair out for several (many) hours, 
I have made a startling finding. 

My ending of my server.xml looks like:

[..stuff ...]
 
 




If the ONLY change I make is moving the JSPInterceptor
tag _below_ the WorkDirSetup Tag, the exception
disappears and tomcat starts up fine ! No other
file is touched, this is the only change I make.
And it works. Now if that is not insane, my 
definition of insanity needs some serious rework.

Try this in reverse in your server.xml, folks, and 
see what happens !

Oh yeah, I only have 1 apps file (apps.xml) and
it says:








Do note that this problem with server.xml is
independent
of the apps.xml file and this file has not been
changed at all. The problem is also independent
of the fact that I am using mod_jk (apache). Seems
like
there is a coding bug in JSPInterceptor.

If anyone here concurs, I suggest forwarding this 
email to an Apache developer.

Please don't top post. Replies go under the
original post. Only MS weenies with MS outlook
top post.

Ok. I am going to rant here. 


Tomcat 3.3.x's internals really suck. I have looked
at probably all of the JDK source over the past
5 years and tomcat is at the very bottom in terms
of quality, readability, even trivialities like
source code formatting/comments.  

JSP/Servlets are *important*. They are probably the
most important java api, now that java has proven
to be a total failure on the client side. (java, in
general, is *great* though).

Now, it wouldn't be so bad that tomcat is a internal
mess, if the exposed API/interface was pleasant.
By this I mean, installing, configuring, extending,
and documentation. Tomcat falls down in all areas.

I mean, I really am very frustrated. There should be
no reason to be. 

Let's take a simple, yet real world example of 2 
virtual hosts, each served by Tomcat.

Well, do I use:

a) 1 tomcat instance with 1 server.xml file with 
different AutoWebApps ? (have you seen how
terse the autowebapp doc is ? They don't even
say if the host name param should be a FQDN) ?

b) 2 separate instances of tomcat with 2 separate
server.xml files ?

c) Some other random, trial by fire combo ?

I mean, in places, the docs say that version 3.3
and earler require separate instances of Tomcat.
Other places, they say things like: "You can add 
apps to multiple virtual hosts." (implying 1 
tomcat server ?).

I don't know. The JSPException that I described in
the original post, is not really documented 
anywhere.  Tomcat should have printed a meaningful
message when that happened. Just barfing up the
Exception itself, doesn't help me, i.e., the end 
user at all. 

There isn't any real documentation, and whatever 
there is, is mutually incompatible in many places. 

Is this the best Sun/Apache can do ? 

And on a personal note: I think the whole "webapp" 
idea is silly. It sounds promising of course, but 
it complicates things for most people. If I am 
running a web site, run with jsp's, then I want:

apache (httpd)
  |
  |_some doc root
|
|__ all .html, .jsp files, images here.

And only one context ("/").

In addition, path or extension based mappings 
_are_ useful but should be the _sole_ domain of
the web server. That would be Apache in my case.

That's how ASP works, that's how LiveWire used
to work. I don't want my images, files etc., all
over the place. I want them all under the htdocs 
directory. (yeah, I know I can do it, but I want
that to be the default out of box tomcat behavior).

"webapps" should never have made it
into the spec. Name three well known
web sites running in a mass virtual hosted 
environment and deployed as "webapps" with 
a web.xml file to boot ! Hell, name *any*.

And the kicker is the gratuitous, idiotic 
use of XML for _configuration_. For you to say:

> servlet.xml cannot have DTD, since people can
> add their own stuff
> (classes), instantiate it in server.xml, and name it
> the way they want,

shows that you have no conceptual idea what xml is
intended for. 

Java:
class foo {
//variables (structure)
}

C:
struct {
 //variables (structure)
 }

Database:
create table [ .. columns/structure ..]

BNF:
syntax ::=  { rule }
rule   ::=  identifier  "::="  expression
expression ::=  term { "|" term }
term   ::=  factor { factor }
[..]

XML is similar to the above 4. XML is a way to
*define*/*create* new and arbitrary data 
formats (although somewhat limited  compared 
to BNF type grammars). This way, I know and
you know what we are saying when we exhange data.

If there is _no_ format (dtd), there _is_ no 
structure. That's a shoddy development time 
hack only. Tomcat has been deployed for years
now. There is no excuse not to have a server.dtd.

Here's a factoid for the sun team: If I 
had the money, I would buy ServletExec or maybe
JRun. I have been hacking java since '94 and
I am frustrated with how inelegant 3.3 "feels".

The Sun/Apache team can learn a great
deal either of those 2 distros. (I am not talking
about fancy installers or GUI's but about 
documentation and error handling behavior). 

The httpd Apache server, has a different heritage
of course, but configuring a complicate beast
like that is *easier* than configuring Tomcat itself.
It took me less than 3 hours to download apache,
compile, install and get 4 virtual hosts up and 
running on my linux box. I have been struggling

Tomcat 3.3, server.xml and a lot of fun

[java programmer]

Hi all:

Tomcat 3.3 (on linux) seems to be quite shoddily
developed. Surprising that, given it's high
visibility and posture.

Consider for instance:

I downloaded the binary distro of tomcat 3.3.
I have set and exported both TOMCAT_HOME and
JAVA_HOME. Compiled and installed mod_jk.so
too. (against Apache 1.3.22). 

All I have to do is edit/configure the 
"conf/server.xml" file and I should be well 
on my way right ?

Well let' see.

shell> vi server.xml
shell> tomcat.sh start -jkconf

EmbededTomcat: exception initializing ContextManager
java.lang.NullPointerException at
org.apache.tomcat.facade.JspInterceptor.addContext(Unknown
Source)

[..bunch of stack trace crap here ..]

Hmm. The message above gives me *no* more information.


Nothing looks obviously wrong with the server.xml 
file, let's validate it using the W3C validator.
But wait, there is *NO* server.dtd. There is only a 
description in the manual which says:

--- quote --
This is the main element in server.xml. It has a
single child describing the tomcat configuration,
ContextManager.

Examples


  ... ( tomcat configuration )
   

ContextManager
- end quote --

Hmm. Well my file kinda looks ok, but not having a 
DTD kinda means that the tomcat developers don't
understand the central concept behind xml. But's
let's leave that aside for now. Let's just validate
the *syntax* of server.xml using W3C (if the 
structure indeed is as simple as the manual claims).

[fire up a browser, validate server.xml here]

Well, that validated fine. So why am I getting
the error and wh am I getting it?  There is no 
way to tell, either from the Exception, or 
the LACK OF DOCUMENTATION.

2 hours later, after random permutations and
combinations of server.xml I still haven't found 
what's wrong. 

Attached below is the complete server.xml, 
in case any of you are interested. 

In the past, I may have gotten upset at having wasted
all this time. But that was before I found enlightment
through tomcat. Now I am at peace with the world for
tomcat teaches us about the futility of trying to
solve simple problems. 

Of course, now that I have given up trying to make
this thing work, I do have some idle time to wonder:

Exactly what are the tomcat developers smoking ?

Hi all,
   Ok so finally I have been able to solve my Tomcat Problem. I am 
writing this for others to not waste 2 days in future.The Problem was 
related to Class Loading. Although I was setting javax.xml.parsers.* 
properties in catalina.bat & my Utilities were working irrespetive of this 
setting(because I have them set using System.setProperty in those classes 
itself. The main problem was related to the way Jasper loads the Xml Parser 
to parse JSPs.
  I followed the instructions of using various XML parser in Tomcat4 & lo & 
behold eveything worked nicely incl. Apache SOAP which is notoriouse of 
working only with old xerces parser i.e xerces 1.2 or before.

Unable to compile JSPs in Tomcat 4

[Jiger Java]

Hi Friends,
I am working on Tomcat 4 Final Release. The scenerio is like 
this.
  I am using XML Schema instead of DTD so I downloaded Lastest Xerces 1.4.3 
since older Xerces were creating problems. I put the latest Xerces.jar file 
in mycontext/WEB-INF/lib. Now these Xml files are read by utility classes in 
a InitServlet to initialize some properties read from XML file. Till this 
everything is working fine. No Exception.
  Then I try to access my context containing index.jsp
then it gives me the following error.


A Servlet Exception Has Occurred

Re: Tomcat 4 and Log4J

[Jiger Java]

Hi Craig,
  Things are working now. What I did was to put log4j.properties in 
WEB-INF/classes & log4j.jar in WEB-INF/lib. But as u will agree this is not 
optimum since I will then have to put log4j.jar in all WEbapps. So I moved 
log4j.jar into common/lib then problems start. If I put log4j.jar in 
$CATALINA_HOME/lib & log4j.properties in $CATALINA_HOME/classes then also it 
works but then now my log4j.properties is shared across all webapps & I cant 
have individual .properties files. Any idea how I can have one log4j.jar but 
individual log4j.properties per webapp. No putting log4j.jar in common/lib & 
.properties in WEB-INF/classes does not work.

Awating ur reply,
Thanks,
Jiger

Tomcat 4 and Log4J

[Jiger Java]

Hi Friends,
I testing Log4j with Tomcat4 RC2. I copied log4j.properties & 
log4j.jar to common/lib. But still I get the following error of Log4j.

log4j:ERROR No appenders could be found for category 
(com.comp.anacreon.utils.MySoapCallerBean).
log4j:ERROR Please initialize the log4j system properly.

I tried various combinations with regards the placing of log4j.properties 
file & log4j.jar file in other words I tried putting them in common/lib, 
mywebapp/lib, set it in the Catalina.bat's classpath, jdk/jre/lib/ext & 
where not. But still no luck. Can anyone explain where do I now put it to 
make the things work.
  I have the old Tomcat 3.2.3 working with log4j perfectly but this problem 
came when I ported my webapp to Tomcat 4.

Awaiting your reply,
Thanking you,
Jiger

  I know that Java2 onwards CLASSPATH var. has been depre. & prefered way is 
to put jars in lib/ext dir of JDK installation. But many times the System 
Classloader does not load it properly.I dont know why but thats true. It is 
better to rely on tried & tested CLASSPATH thingi then on experimental 
lib/ext one.

Tomcat 4 RC 2 doubts

[Jiger Java]

Hi friends,
   This is my first mail to such a wondefull group.Well I just
downloaded Tomcat Rc2 (and tried to convince my boss to use it).
But frankly speaking I found some weird diffiulty installing Rc1 & Rc2.
Now I understand that Tomcat 4 has a major architecture changes like
Custom Classloaders & places to store jar files etc.
But I have some queries hope I will be guided properly.
Doubt No.
1. Since Tomcat 4 uses its own Classloaders it does not recognise the JDK
CLASSPATH variable.Now what do I do if I want a set of libraries which I
have installed in JDK(set in CLASSPATH variable) & also to be used by
tomcat. Putting things in two places wold be cumbersome.Dont youall feel so.
2. If I try to add CLASSPATH in the catalina.bat file along with its
CLASSPATH then TOmcat starts giving out strange errors. For e.g In my app I
was using Custom Tags & appending the classpath in catalina gave me
NoClassDefFound for TagSupport class of JSP when the Sample Custom Tag
example worked normally. How do I integrate JDK classpath with Tomcat
CLASSPATH without any hitches.
3. I am believing that Tomcat no longer allows extraced classes in the lib
dir. only .jars are allowed & all non-jars libraries should be kept in
classes dir. but this is very non-intutive coz it confuses us with servlets
& libraries. Should the pre-Tomcat 4 standard of keeping non-jars in lib &
then brought into CLASSPATH in tomcat.bat/catalina.bat work. Any specific
reasons.

THere are many more doubts guys but please enlighten me with these atleast.

Keep up the good work.
Thanks,
Jiger

Apache+Tomcat+SSL+IE5.5

[java]

Hi,
I have a web server with Apache (with SSL) + Tomcat (with ajp13)
Tomcat don't have a HTTP connector.
My application only use JSP-servlets(no static page).
It work perfectly with IE5.0 , Netscape 4 or Netscape 6
When I use IE5.5 to connect to my apache i have this message from IE :
(i have a french message, so it is my translation )

"this page have secure elements and non-secure elements

Would you like view the non-secure elements ?"

It's just a warning message but I would like to know if :

 _ IE5.5 is right (they are non-secured element in my JSP pages) or if
it is a bug.
 How to be sure ?

 _ if yes, Does It mean apache-SSL don't crypt my tomcat's JSP. (i have
the same message when i use ajp12 or ajp13 )

Thanks in advance
Fred

This is a restrictive option.  It's much better to use one of the
many XML/XSL based packages and generate from there.  In this way
you can extend the document definitions as needed which with TeX/LaTeX
is possible but not the preferable solution in my book.

TOMCATs SERVLET-Reload

[java . harjes]

Hi

It's confusing

I'm working with TOMCAT 3.2.1 an a LINUX machine. In the TOMCAT -
configuration-files I switched on the automatic reload of servlets, if they
were
changed. Why does it happen that sometimes the reload is done and sometimes
not???

Is there anyone who has an explanation or an idea?

Thanks
Jens

SERVLET-Reload

[java . harjes]

Hi

It's confusing

I'm working with TOMCAT 3.2.1 an a LINUX machine. In the TOMCAT -
configuration-files I switched on the automatic reload of servlets, if they were
changed. Why does it happen that sometimes the reload is done and sometimes not???

Is there anyone who has an explanation or an idea?

Thanks
Jens

hotspot jvm crashes in production

[Java Poop]

Hi -

We have recently moved our production site to use JSPs with Tomcat
3.2.1/Apache 1.3.17/Sun JDK 1.3.0/Solaris 2.6. After running for a couple of
hours, our JVM crashes with the following error:

An irrecoverable stack overflow has occurred.
#
# HotSpot Virtual Machine Error, Unexpected Signal 11
# Please report this error at
# http://java.sun.com/cgi-bin/bugreport.cgi

#
# Problematic Thread: prio=5 tid=0x2149d0 nid=0x25 runnable

Has anyone seen similiar problems? Is there anything in the settings we
could set to avoid this?

TOMCAT and APACHE

[java . harjes]

Hi experts,

I have some problems in integrating TOMCAT and APACHE like it is described
in your "Minimalistic User's Guide".

My Apache Webserver Version 1.3.14-6 is running on a SUSE 7.1 - LINUX
machine and it works fine for itself.
The Tomcat Version is 3.1-70 and also this application works fine as a
stand-alone server, i.e. I get contact to the servlets via the 8080 port.

Now I tried to integrate both components:

  (1) I appended the /conf/tomcat-apache.conf to the httpd.conf

   A restart of the httpd failed, the error log said that the
mod_jserv.so couldn't be found in the directory: /usr/local/httpd/libexec

   There was indeed no such directory!?
  (2) So I created it and copied the existing mod_jserv.so - file from the
directory /usr/lib/apache to /usr/local/httpd/libexec

   A restart of the httpd was now successfull but the apache webserver
didn't answer on requests !?
   The error-log file said:

   [Fri Apr 20 19:14:02 2001] [emerg] JServ: Error setting defaults:
ApJServLogFile: file '/usr/local/httpd/./logs/mod_jserv.log' can't be opened
   [Fri Apr 20 19:14:02 2001] [crit] (2)No such file or directory:
Apache JServ encountered a fatal error; check your ApJServLogFile for
details if none are present in this file.  Exiting.

  (3) Following chapter "Obtaining the Jserv Module" in your "Minimalistic
User's Guide"  I downloaded the tomcat source jakarta-tomcat-3.1.1-src
   and executed the build command apxs -c -o mod_jserv.so *.c.

   The building of mod_jserv.so was no problem and successfully.

   Then I copied the new mod_jserv.so - file to /usr/local/httpd/libexec

   A restart of the httpd was again successfull but the apache webserver
didn't answer on requests again!?
   The error-log file said the same:

   [Fri Apr 20 19:14:02 2001] [emerg] JServ: Error setting defaults:
ApJServLogFile: file '/usr/local/httpd/./logs/mod_jserv.log' can't be opened
   [Fri Apr 20 19:14:02 2001] [crit] (2)No such file or directory:
Apache JServ encountered a fatal error; check your ApJServLogFile for
details if none are present in this file.  Exiting.



What shall I do?
I hope you can help me


Thanks a lot

Re: getResourceAsStream - properties files

[Java Poop]

Craig -

I think I found a way to make it work ---

InputStream stream =
Thread.currentThread().getContextClassLoader().getResourceAsStream("myApp.pr
operties");

That loaded my file from %TOMCAT_HOME%/lib directory. Should I be concerned
about portability? Will this work in the Tomcat 4.0 world?

thanx,
JP

Craig - Thanks for the quick response..:)

I tried to follow what you suggested, but, neither suggestion worked. See

I'm trying this from within a simple class (which extends, implements
nothing) that I'm instantiating from a servlet. The class file is in the
/classes directory (although it is in a package --- com.company.blah). I
tried putting the properties file in the classes, lib and the actual
directory where the class is... but nothing works. I get a null stream.

So you are saying that I should put a war file in the webapps directory,
plus create a directory with the same name of the webapp and put the
properties file into the WEB-INF directory? ie, so my directory listing
would look like:

/webapps/myapp.war
/webapps/myapp/WEB-INF/myApp.properties

If myapp.war also contained myApp.properties, wouldn't the war file get
un'jard by tomcat and then overrite my file? (I would like to put a default
properties in my war file in case someone has not setup a properties file.)

Also, from within a class instantiated by the servlet, can I call
getServletContext()? Do I need to pass it in?  If this class were to
eventually become a bean or taglib, what do you suggest for handling
configuration file loading.

Thanks in advance,
JP

getResourceAsStream - properties files

[Java Poop]

Hey guys-
 
I'm trying to figure out way to separate my 
initialization parameters from my application.war file. Because certain things 
are different between dev, qa and live machines (such as database hostname, 
username, password, etcs), I rather not put these values in the web.xml file. 
(The web.xml would be stuck in the application.war file and I don't want the 
deployment people to unjar it in a deployment setting to change the values of 
web.xml).
 
So, I'm looking at trying to setup my own 
properties file that a singleton class would read in my web application and set 
as global variables for all my servlets/jsps. However, I'm having trouble 
writing the code to open up the properties file. I'd like to put the properties 
file in %TOMCAT_HOME%/settings directory (I made this directory up and added it 
to the classpath in my tomcat.bat file).
 
From some previous posts on this list, I'm trying 
:
 
InputStream stream = 
this.getClass().getResourceAsStream("testApp.properties");
But it fails. If I use a File stream and point 
right at the file, it does load. Just as a test, I tried copying this file to 
the same location where the class was, as well as myapplication/WEB-INF/classes 
and myapplication/WEB-INF/lib, and still could not get the file 
loaded.
 
What would be the proper way to have this loaded 
(preferably in the settings directory since I can't rely on my war file being 
unjar'd by future tomcats).
 
BTW- I'm using Tomcat 3.2.1 in Standalone, Win2K, 
JDK1.3.
 
Thanks in advance,
JP

Re: Caching a servlet? Sessions in IE?

[Java Poop]

Have you tried setting the cache and expire headers?

Try addding:

response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader ("Expires", 0); //prevents caching at the proxy
server

URL rewriting in Tomcat

[java]

I'm writing a 
servlet that uses session tracking with URL rewriting (noCookies="true"). I'm 
using Tomcat 3.2.1.
When the servlet is 
located in webapps/Root/Web-inf/classes, it works fine, and the URLs are 
rewritten with the appropriate session ID, but when the servlet is located 
in another folder under the webapps folder (webapps/<>/Web-inf/classes), the session ID is not added to the 
URLs.
I suppose it has 
something to do with web application configuration (in the "/conf" folder 
perhaps?) but I couldn't find how to make it work in another web application 
other than the default.
Any ideas 
anyone?
