RE: Web Application Question
Joe, Are you sure your filter is doing the right thing? Sounds like it may be forwarding to a bad URL or something. If it works without the web.xml then I assume you've set up your context for the /cms application. Maybe try a System.err.println( myDestURL ) in the filter and then copy/paste that output into your browser to see it exists. Hope this helps. Chris Ward Hello, I'm running Tomcat 5.5.7, and right now I have one application ( the default application ). I just created a new dir ( $CATALINA_HOME/webapps/cms ) for a new application. The home page ( index.jsp ), for the application, is just a simple jsp file with static content. Once I added a WEB-INF/web.xml file, with just filter filter-mapping tags, and my welcome-file list, and browse to the application I get a 404 error. Now, if I remove the web.xml file from the WEB-INF/web.xml directory, I see the correct index.jsp. I'm looking in the $CATALINA_HOME/logs/catalina.out file and see nothing. I have watched the file, using tail -f during start up, and don't see any message about a misconfiguration in my web-xml file. Am I missing a step in the process of creating a new web application? Any help would be appreciated.

Mulitple JVMs
Dear All, Due to a version upgrade of some third-party component accessed through J-Integra (Java/COM bridge) I've been informed that I need to run the new version in a different JVM to the rest of my webapp (the earlier versions lived in harmony). I know I could have a separate Tomcat on a different (or the same) server dedicated to running the new stuff, but I wondered if anyone has any advice on this. Many thanks, Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Mulitple JVMs
Hi, One webapp can only run in one JVM. But if you are splitting your webapp, you can use the CATALINA_BASE/CATALINA_HOME approach QM referred to, or have an entirely new Tomcat instance. It doesn't make that big a difference. That's is what I thought, but thanks for verifying it. Consider also making the rest of your webapp run in the new JVM, so that you stay in harmony. Ah, now, there's the rub. One of my webapps uses the COM/Java bridge to talk to a COM app (Bloomberg) on a REMOTE machine and requires the bridge to be run in DCOM mode. Something in the *new* version of my other COM componenet (Monis) apparently dictates use of NATIVE mode for the bridge. This COM app is on the same machine as Tomcat. Before the new version, it would happily run in non-native mode. The folks who produce the bridge code confirm what I'd found in extensive tests... Unfortunately, J-Integra is not designed to run in both native mode and DCOM mode within the same JVM. My suggestion is to alter your architecture such that Bloomberg and Monis are accessed from separate JVM instances. So the most painless thing would be to install Bloomberg on all the machines that will be running Tomcat. Just so you see why I asked the question.

Chris, For what it's worth, I spent ages trying to get a remember-me login thing going out of the box but never managed it.

RE: WAR file deployment snag - any suggestions?
Thanks very much for this. There are some very good points in here that have got me thinking. At present I have only one Tomcat running and a small number of users (it's an intranet) but the complexity and resource requirements of the application set is growing. I don't have any experience of larger scale web systems so all suggestions are welcome. Saving the XML files was an initial step at caching things that I can control. I did play around with holding onto the (dom4j) Documents in the ServletContext but I was concerned that this would swallow all the memory unless I used some sort of soft-reference caching system. I posted a question about this to this list - but I never heard back - must have been too dull a question (or the wrong list)! I imagine spreading the apps over multiple Tomcats/machines would allow me to do more in-memory caching. Feels like this is a move toward Web Services - I don't know much about them. Thanks again for your response - I'd be interested in hearing any other pearls of wisdom.

The idea is to setup a directory outside of the Tomcat context path -- specify it in a properties file, or in a context param, whatever -- and write the data there. As the system grows to support multiple Tomcat instances spread across different machines, you could share the filesystem via NFS (not pretty, but it works), stuff the docs in a database (not pretty, but it works), or have the mid-tier Tomcat instances push the data to another, internal Tomcat setup that writes the files to a clustered/RAID'd fs. etc, etc, depending on how valuable these docs are and how much this app grows. By not writing to your context, you can wrap everything up in a WAR file and, better still, gain (a little) more security by making the WAR file owned and served by two different user accounts. -QM -- software -- http://www.brandxdev.net tech news -- http://www.RoarNetworX.com - 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: JSTL 11 with Tomcat 5.0.27
Hi,
I went back to first principles and you are quite correct, things
do seem to be functioning properly.
Thanks very much for the patient help.
In the course of doing all this I downloaded the JSTL 1.1 zip from
the Jakarata site so I could test the standard-examples WAR file.
However, I now find that there seems to be something problematic with
loading,
using c:import, an XSLT stylesheet from file for use with the
x:transform
If I copy the guts of the stylesheet into my JSP locally it seems to
work fine.
In short;
c:set var=XSL
c:import
url=../xsl/CubeToPositionHistory.xsl/
/c:set
Fails in the
x:transform doc=${XML} xslt=${XSL}
x:param name=POS_ID_STR
value=${param.POS_ID_STR} /
/x:transform
Whereas
c:set var=XSL
...
contents of
../xsl/CubeToPositionHistory.xsl
...
/c:set
works as anticipated.
I must be doing something wrong or something subtle has changed.
I know the import is working because I've output the ${XSL} to the
screen
in the first example.
Any thoughts gratefully received.
Chris
But does a simple
%@ taglib prefix=c uri=http://java.sun.com/jsp/jstl/core;
% c:set var=test value=hello/ ${test}
work!

JSTL 11 with Tomcat 5.0.27
Hi, I've upgraded from Tomcat 4.1.24 to Tomcat 5.0.27, most of my JSPs that use JSTL (1.0) work with the new setup, but none of the XML tags work. Pages just bomb out - nothing in the browser, nothing in the console, nothing in the logs. Even just using x:parse Since the core and sql tags do work I believe I am picking things up okay (I copied jstl.jar and standard.jar into my /lib dir and I notice the .tld files are in the standard.jar file). Does this smell like a parser jar file problem? Any ideas? This is sucking up all my time and delaying a release. Best regards Chris p.s. I notice in some docs that the url for JSTL 1.1 tags are like this %@ taglib prefix=x uri=http://java.sun.com/jsp/jstl/xml; % rather than %@ taglib prefix=x uri=http://java.sun.com/jstl/xml; % - the new one doesn't seem to work for me. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

RE: Tomcat Holding Database Open??????
Hi Mike,
Some thoughts. If anyone sees errors please let me know -
it may save me time in the long run!
Tomcat doing this, because my Application ran just fine,
using MySQL,
and JDBC driver in a Web Server called OmniCron in CGI
If I recall correctly, the CGI approach throws everything
away after each request. I moved from Perl CGI to Java
Servlets a few years back partly to make use of the
load-once-then
-reuse aspect. I think there was Mod Perl or something
that sort of did this with Perl.
Any road up, you may find that that is why the CGI version
worked. Maybe it was freeing/releasing things when the
CGI script/prog finished each request. You got a virgin
state every time.
format. The only thing different now is, Im trying to
run SERVLETS using Apache/Tomcat. At the Start of each
Servlet I do a connect to database CONNECT TO
'jdbc:mysql://127.0.0.1:3306/Imagescan'
DRIVER 'com.mysql.jdbc.Driver'
Then do my processing and then do a DISCONNECT ALL..
Are you sure the disconnect all is being fired when
you think it is?
Also, is there any chance the the disconnect all is
freeing something you later depend on in subsequent
requests? For example, do you have an init() method
in your servlet that (initially) creates/connects,
and the doGet/doPost then uses the connection?
If this is the case, check the disconnect all is not
closing/nullifying the connections since the init()
won't get fired again. This might explain why the CGI
implementation did make it through.
It just does not make sense I can connect ONE TIME only when running a
Servlet and have to back out of app, STOP, START, and go
back in, to
get another one time connection.the 08002, connection
name in use,
to me, points to Tomcat ..
But as I said, Im just a baby in diapers to this world..
I believe its
something in one of the .xml files, but I have no idea.
I don't know for sure - but it sounds like the sort
of right-of-passage problem most of us have had when
first starting with servlets.
I'd recommend gratuitous use of;
System.err.println( Now executing {your method name}
);
then stare at the console window for Tomcat to see what's being
executed. It's always my last port of call for this sort of
thing.
As for Connection Pooling,is that for a system taking
large numbers of
hits on it? Right now, Im just one guy trying to make
one connection work.
I use connection pooling on my intranet site which has
low traffic but large/complex applications on the server.
I use it for two reasons;
a) It shifts some of the work to a thirdparty
bunch of code that I didn't have to write
b) Saves time on the creation/connection cycle
for DB-centric applications.

Tomcat 5 : JSTL (x:transform fails silently
Hi,
I've moved to Tomcat 5 over the last week but I now find a JSP
that worked on Tomcat 4.1.24 fails when it gets to the x:transform.
I can't find an error anywhere.
I looked at the JSTL 1.1 spec' (that's what Tomcat 5 uses right?) and
noticed x:transform parameters changed from
x:transform xml=...foo... xslt=...bar.../
to
x:transform doc=...foo... xslt=...bar.../
but that doesn't seem to solve it.
BTW : I have copied
jstl.jar
standard.jar
to my webapp/WEB-INF/lib dir from the out-of-the-box Tomcat 5
jsp-examples webapp.
Any ideas? Do I need to include crimson.jar or something? I don't
think I do.
Best regards
Chris

Subject: Re: Tomcat causes Apache to hang. Any ideas?
Sorry, this is a shared server, and he wants his site
available on
port 80.
Tomcat standalone can run on port 80 without running as
root by using
jsvc (from commons-daemon). There are examples and more
information
on this configuration at
http://jakarta.apache.org/tomcat/faq/security.html#jsvcExample.
Maybe I am missing something, but wouldn't that not be able
to bind to
port 80 since Apache is already bound to it? There is a lot
about the
Java world I am not familiar with, so maybe it can...
You would need separate ip addresses for apache and tomcat.
reason we hand everything off, is because he has his application
hosted inside a directory (ie: ~/public_html/appdir) but
wants it to
be available to users as http://www.domainname.com/whatever.jsp
instead of http://www.domainname.com/appdir/whatever.jsp.
You can configure Tomcat to have a Context whose docbase is
~/public_html/appdir but whose path is (the empty
string, not null
or /).
And indeed that is what we are doing for him right now. However, my
previous attempts at fiddling with mod_rewrite to translate root
request /whatever.jsp into /appdir/whatever.jsp had failed.
I now have
this working in a preliminary stage. Since I was unable to get
mod_rewrite processing the requests right, we just did a
jkMount /*
workername, which passed every request off to tomcat,
and since we
had the root context setup to serve from
~/public_html/appdir it all
worked out fine. But of course, this results in trying to pass PHP
requests (and things outside the appdir) to tomcat.
how about passing only requests that are not php to tomcat?
You can do this in httpd.conf: LocationMatch ^/(?!phpdir)
jkUriSet ...
/LocationMatch
He also wants to use PHP
on his main domain for forums or some such, once we get
him to move
his application out of appdir and into his website root.
This is the deal breaker I think, for a commercial organization
anyways. While you can use PHP on Tomcat, the performance is
apparently not good enough for a large scale installation. See
http://wiki.apache.org/jakarta-tomcat/UsingPhp for how to do this
anyways.
Well, I don't think I want to run PHP through Tomcat as we already
have Apache running with PHP and it runs solid (and quite
snappy too).
What I am currently working on is this for his .htaccess (well,
testing on a test instance): ( snip )
RewriteEngine On
RewriteCond %{REQUEST_URI} !^/appdir/
RewriteRule ^(.*\.jsp)$ /appdir/$1
---( /snip )-
This results in all jsp pages being sent to tomcat. I also added a
jkMount /appdir/* workername to the httpd.conf file. This means,
that in the user's JSP pages, if he uses absolute paths for images,
css, etc then they will be handed off to tomcat as well so that a
complete page is sent back.
The problem currently is, the user used relative paths for all his
images, css files, etc. So while the JSP is being served correctly
from Tomcat with the above .htaccess lines, it is not
passing the css
and image files off, which is the expected behavior. So I
am trying to
find some way to remedy this via

Mid-size dynamic XML (DOM) result handling in Tomcat.
Hi all, I'm not sure if my question should be addressed to the Tomcat or dom4j list, so this is going to both. I'm running Tomcat for my company intranet and most of my Java applications return their results as XML so that I can style the data with XSLT. I am using dom4j to dynamically build up the DOM (dom4j Document) and I pass that to a Transformer in a servlet. Since I want to slice'n'dice these results with XSLT, I am keeping hold of the Document on the server using an HttpSession entry so it's sitting there as I apply the different stylesheets (specified as a servlet parameter). I've read that dom4j in-memory representations are 8-to-10 times the size of the XML text - so I am very aware that my solution is not scalable (my current project results are about 1MB on disc). Is there a best practice for this sort of thing? Should I be serializing the Document to a DB or something and just keeping a handle to that in the HttpSessions? Should I be using SAX in some clever way? I'm sure it's a common task to handle medium-sized results from Tomcat. Any input would be gratefully received.

RE: JDBC/DBCP problems
Hi Jay,
I don't know if it's of any help at all, but I went through
something similar.
What I found to be my problem was that my URLs for invoking
JSPs/servlets did not always specify my Tomcat Context and
all the DataSource stuff was set up in my context (in server.xml
and the associated web.xml).
Since I had pointed the default Context / to my Context
(/hal) by setting it's docBase in server.xml most of the requests
appeared to be working.
For example, if I asked for
{host}/jsp/myJSP.jsp
I would get in fact reach the JSP at...
{host}/hal/jsp/myJSP.jsp)
but the JNDI stuff did not get picked up. Leaving the /hal
out of my request meant it never saw the /hal stuff in server.xml
which is where my DataSource stuff lives.
I cleaned up my URL in links/forms etc. and seemed to get on okay.
Hope it helps a bit.
Best regards
Chris

Subject: JDBC/DBCP problems
I'm obviously missing something important with regards to
moving our database/JDBC connectivity to use JNDI
DataSource/DBCP. I've read and re-read the docs, looked at
every related message in the archive, and Google'd every set
of keywords I can think of, but still no luck. Here's the issue:
Tomcat version is 4.1.29 on Windows XP. I'm attempting to
connect to SQL Server. The JDBC driver JARs are in
CATALINA_HOME\common\lib, and since everything works fine if
I manually load the driver via Class.forName(), I don't think
my problem is related to my driver files location. When
attempting to use getConnection(), however, I get the dreaded
Cannot create JDBC driver of class '' for connect URL 'null',
cause: No suitable driver error. The highlights of my
configuration are below.

envContext.lookup(jdbc/mydb); Connection conn =
dataSource.getConnection(); // throws exception

Further info:
-
Adding the following line after acquiring dataSource above, I
get class
org.apache.commons.dbcp.BasicDataSource:
System.out.println(dataSource.getClass());
And if I add the following, I get
[EMAIL PROTECTED]:
System.out.println((org.apache.commons.dbcp.BasicDataSource)
dataSource);
So, since it looks like a valid BasicDataSource object, I
tried the following, but get null back:
System.out.println(((org.apache.commons.dbcp.BasicDataSource)
dataSource).getUrl());
This seems to indicate that the object isn't initialized?
Turning on debug for the relevant listeners
(NamingContextListener and GlobalResourcesLifecycleListener),
I see the following related info in my Tomcat console window,

RE: Repeated load-on-startup niggle
Correct - the only place the Filter is mentioned is in the web.xml for the / Context and the .class file is in that Context. If it further confirms your understanding, I should mention that in the beginning I *did* have a copy of the Filter under /hal (for initial testing of the Filter) and that caused an infinite loop for redirections! The first request to / got redirected to /hal which then got redirected to /hal etc. etc. Chris Chris, thanks for responding. I think I understand.

RE: Repeated load-on-startup niggle
Howdy, But he wants to redirect all requests, not just those for /. Exactly. I did in fact have an index.html which did a redirect to /hal so it looks like I'd tried that solution in the dim and distant past. Obviously once I had pointed / at /hal using it's docBase attribute (in server.xml) the /index.html never got processed. All of this is required to keep current users from having to update their URLs (they do a lot of web query imports to Excel) whilst avoiding the stuff in the /hal Context being initialised for both / and /hal.

RE: Repeated load-on-startup niggle
Hi, This would be fine if the everyone started at the entry level of the web site, but a lot of my problems are caused by including/importing resources like javascript files, servlets, etc. etc. e.g.Most od my generated HTML files have SCRIPT SRC=/JavaScript/HAL_CommonJavaScript.js LANGUAGE=JAVASCRIPT TYPE=TEXT/JAVASCRIPT /SCRIPT But that JavaScript file really should be /hal/JavaScript/HAL_CommonJavaScript.js So it would never see the redirection from /index.html. I was lazy in the early stages and now it's biting me in the bum! I guess I'm imagining this situation... www.foo.com/ and www.foo.com/hal/ Someone types in the first one, because they're lazy. Immediately they're redirected to /hal, and from then on, they stay there. ie: There's nothing at all at / other than the redirect.

RE: Repeated load-on-startup niggle
I would use sendRedirect in this case for two reasons:
- To really make it look/act as if the request was for the /hal URL,
- To avoid getting a RequestDispatcher for a resource outside
your docBase
sendRedirect would preserve all the request parameters,
including POST data.
Hi Yoav,
Below is the filter I've been using. It seems to mostly work,
but any image files from a path such as /images/Delete.gif
seem to not get updated to /hal/images/Delete.gif in the

However, the output I get to System.out *does* show the filter
processing these requests. Any ideas? Is this the correct way
to implement the filter?

RE: Repeated load-on-startup niggle
Hmm, that's strange. Enable the AccessLogValve (in
server.xml) so that you can see what's actually being
requested from the server.
Seems to request both versions...
try

System.out.println( REQ : getRequestURI : +
request.getRequestURI()
);
String filteredURL = /hal+request.getRequestURI();
System.out.println( filteredURL );
//chain.doFilter(request, response);
response.sendRedirect(response.encodeRedirectURL(filteredURL));
It might not matter to you, but I think this code would drop
the query string from the forward URL. Test to make sure it
doesn't, or it if does add the request.getQueryStrign() to
filterURL (before encoding).
So you get the image forward URLs in your System.out output?

RE: criteria for a session
I thought sessions were essentially browser sessions. For anything I've done that requires knowledge of user state between different browsers (but same machine) I've used cookies to save some form of user id. I did turn on the Tomcat setting for persistent sessions and found that preserved session in the same browser with a Tomcat reboot. I guess you could serialise sessions to a DB and retrieve from user id in a cookie - or am I losing the plot now? Best regards Chris what are the criteria for tomcat 4.1.26 to say the session is null (((HttpServletRequest)request).getSession(false))? It seams to depend on something in the request. When i open a second new IE Window, not a child from the first IE Window, the session is null. I dontt call session.invalidate() and the timeout is not reached. I know that there are only two reasons for invalidate a session. 1) session.invalidate(); 2) session timeout I thought these where the only reasons.

Howdy, Perhaps a case-sensitivity issue? What happens if you use Redirect instead of redirect?

RE: Xalan redirect (to file) within Tomcat
Howdy, I don't know Xalan well enough to answer, but it seems pretty clear tomcat is looking for a class called Redirect, while the stylesheet uses redirect. It seems like a case-sensitivity issue, but I can't help much beyond that ;) Yoav Shapira I agree. Anyway, a few Googles later and I found this http://www.biglist.com/lists/xsl-list/archives/200309/msg00716.html which uses an alternative namespace declaration... ... xmlns:redirect=org.apache.xalan.xslt.extensions.Redirect extension-element-prefixes=redirect and this seems to work for me. I don't know if there is anything sinister about using this different declaration, and I am confused (like the guy in the above mail thread) as to why the other declaration of xmlns:redirect=http://xml.apache.org/xalan/redirect; works in my command line tests.

Persistent User Login
Hi, I was asking about this subject on this list a while back http://www.mail-archive.com/tomcat-user%40jakarta.apache.org/msg111700.h tml but I've not managed to get it working yet. In short. I'm working on an intranet application and I want my users to only have to log in once. If they start a new browser session it should pick up their details and not ask them to log in. I expect the username/password should live in a persistent cookie, and I've been using FORM based authentication on Tomcat 4.1.23. I've spent days faffing about with redirects from servlets to j_security_check (which has never worked for me) and filters on / etc. etc. etc. I came back to this today and played with Single Sign-on and Persistent sessions in the hope that might do it. Does anyone out there have this working? Best regards Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Persistent User Login
Thanks. I should have mentioned that I am running Tomcat 4.1.24 with jdk1.3.0_02. I did want to make use of the Tomcat features for authentication (i.e. FROM method, Realm using user/roles DB tables, web.xml configuration etc.) to replace existing code that I wrote for the task. I'm losing the will to do this now though. Anyone done it with this set up? J2EE 1.4 SDK (which contains Tomcat 5) uses the Single Sign on feature and it is working fine.

It's standard container managed security stuff - I first invoke a
protected URL - in index.jsp - I redirect to mainMenu.do -
and *.do is
protected. Based on security constraints in web.xml, I'm presented
with a form-login-page login.jsp - rather than having
action=j_security_check in this form, I have
action=/security/authorize - which is mapped to my own
LoginServlet.
In the LoginServlet, I encrypt the password (optionally based on an
init-parameter), set some cookies and do an HTTP Post to
j_security_check. Works on Tomcat 4-5 and Resin 3.x.

I've actually improved the Remember Me feature a fair

However, the URL
tends to show up in server log files which can be a

Because of this, I changed to using an HTTP Post with Jakarta
Common's HttpClient. I also moved my form-login-page and
form-error-page into a security folder and then set my
cookies for
the /appname/security path rather than / - this makes it so the
user/pass cookies are more secure and can only be retrieved when
logging in, rather than for any URL in the site.

RE: Intermittent failures using DataSources
Hi,
For the record, I solved my problem regarding the message...
org.apache.jasper.JasperException:
Unable to get connection, DataSource invalid: Cannot load JDBC
driver class 'null'
... from my JSPs.
For anyone who is interested, here's what worked for me...
I was not always invoking them with my context in the URL.
Since I had set my default context's docBase the same as my properly
configured
one, it *appeared* to be executing the JSP in the same way. In fact,
this seems
okay for getting to static html pages, but the JSPs were not picking up
the DataSources
Resource or ResourceLink settings.
Example.
Bad : http: //{my server}/apps/admin/MyApplication/myJSP.jsp
Tries to process JSP, fails with above exception.
Good : http: //{my
server}/MY_CONTEXT/apps/admin/MyApplication/myJSP.jsp
Does the business.
Of course, now I feel dumb. But I hope this may help some other poor
soul from blowing a day and a half.
Best regards

Intermittent failures using DataSources
Hi all,
Please excuse any going over of old ground with this question, I have
searched every archive
I can find. I have recently started using DataSources from JSPs using
the JSTL taglib (I think
this is a Tomcat rather than taglib question).
I've got a Context for my apps and initially had my bunch of
DataSources set up within
the Context.
No problems. Happy, happy.
Anyway - a few days ago I set up the required database tables to support
a DataSourceRealm
for FORM authentication and I moved all my DataSource config up to the
GlobalNamingResources
since I'm sure I read somewhere that this had to be done.
That initially caused me problems until I added a ResourceLink to my
Context for each DataSource
. . . . . .
Context path=/hal docBase=hal debug=0 privileged=true
reloadable=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=HAL. suffix=.txt timestamp=true/
!-- DataSources moved from here to
GlobalNamingResources area --
Realm
className=org.apache.catalina.realm.DataSourceRealm debug=99
dataSourceName=jdbc/Id userTable=HAL_UserId
userNameCol=Name userCredCol=Password
userRoleTable=HAL_UserRole roleNameCol=Role
/
ResourceLink name=jdbc/Id global=jdbc/Id
type=javax.sql.DataSource/
ResourceLink name=jdbc/Static global=jdbc/Static
type=javax.sql.DataSource/
ResourceLink name=jdbc/Params global=jdbc/Params
type=javax.sql.DataSource/
ResourceLink name=jdbc/Control global=jdbc/Control
type=javax.sql.DataSource/
ResourceLink name=jdbc/SelmaData
global=jdbc/SelmaData type=javax.sql.DataSource/
ResourceLink name=jdbc/BartData
global=jdbc/BartData type=javax.sql.DataSource/
ResourceLink name=jdbc/Beauchamp
global=jdbc/Beauchamp type=javax.sql.DataSource/
/Context
. . . . . .
All the DataSources are set up along these lines..
. . . . . .
Resource name=jdbc/Id auth=Container
type=javax.sql.DataSource/
ResourceParams name=jdbc/Id
parameter
nameusername/name
value{deleted in mail}/value

parameter
namedriverClassName/name
valuecom.inet.tds.TdsDriver/value
/parameter
parameter
nameurl/name
value{deleted in mail}/value
/parameter
/ResourceParams
. . . . . .
So I think everthing looks okay.
Problems
1) With the above setup I get...
ServerLifecycleListener: createMBeans: MBeanException
java.lang.Exception: ManagedBean is not found with DataSourceRealm
at
org.apache.catalina.mbeans.MBeanUtils.createMBean(MBeanUtils.java:642)

Listener
className=org.apache.catalina.mbeans.ServerLifecycleListener
debug=0/
Listener
className=org.apache.catalina.mbeans.GlobalResourcesLifecycleListener
debug=0/
If I *do* comment them out the Tomcat Admin tool will complain.
2) Sometimes my JSPs just start failing with this message...
org.apache.jasper.JasperException: Unable to get connection, DataSource
invalid: Cannot load JDBC driver class 'null'
at
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.ja
va:254)
at
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295)
even though they may have been running fine beforehand.
Any help would be great. Sorry for the length of the message, it's
driving me
crazy!
Many thanks,
Chris

The alternative is to make individual command servlets that have a common base class and sit on separate URLs. The problem with option two is that the servlet connects to EJB on the back end and could potentially hold onto allot of resources. The problem with option two, possibly, is federation. If there are hundreds of requests coming, will tomcat federate the servlet or pipe everything through one hole? 1. Take a look at struts. It will handle the direction of the request to the proper resource based on the 50 actions (which you call commands above) you define. 2. Simply put: don't worry about federation. Let tomcat worry about how many instances of the servlet it needs, how many request processing threads it needs, etc. Tomcat does a good job at this, and some of the relevant parameters (maxProcessors etc.) are user-tunable as well. We, as well as many other people on this list, run tomcat instances that handle thousands of requests.

JServ is dead code. Don't use it. Tomcat is that same code's successor. Also, you'll need "mod_jk" to glue Tomcat to Apache. I only mention it because I spent two days finding this out! Most of that time was spent hunting for mod_jserv. D'oh! Look at http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/mod_jk-howto.htm l for specifics. Chris
Pentium IV - any known problems?????
Hi, I've been looking for anything in the archive but couldn't see anything to help me. Feel free to ignore this but I'm puzzled so anything would be a step forward! Basically, I'm trying to get Tomcat up and running on a Pentium IV PC - does anyone know of any reason why this would fail? I only ask because my Visual Cafe 4.0 was unsupported on P IV and that spooked me. I've got jdk13 installed and my "HelloWorld" test works. I've set JAVA_HOME and TOMCAT_HOME but runing "startup" brings up a dos window that then disappears without any error. I followed the installation guide I found here, www.onjava.com/lpt/a/729 maybe it misses something out. I'm currently eyeballing the startup scripts Thanks for your time, Chris
RE: Pentium IV - any known problems?????
Ignore me - I was being an idiot. All better now! Thanks anyway, Chris
RE: Pentium IV - any known problems?????
Thanks for this suggestion. I had been doing just this then someone suggested a Restart of my PC. Since I had not done this since installing my new Visual Cafe, the PC was confused about the Java environment. The restart sorted it all out. Thanks again, Chris -Original Message- From: Benot Jacquemont [mailto:[EMAIL PROTECTED]] Sent: Tuesday, 17 April 2001 16:02 To: [EMAIL PROTECTED] Subject: RE: Pentium IV - any known problems? First of all, open a dos window, go to your TOMCAT_HOME (cd TOMCAT_HOME), go to the bin, and execute tomcat run instead of double clicking on the startup.bat script. It is a every-day-repeated trick to see what is the error when the window is closing. So please write it down somewhere ! (;-) ).

RE: Pentium IV - any known problems?????
Just for closure on this - my problem was a failure to restart my machine after upgrading my Visual Cafe to the P IV friendly version earlier in the process. The restart did the trick and things seem fine. I was trying to fix a problem that was not there! Thanks to everyone for their help.

As to the PIV - I am currently using one without problem, though Sun does recommend only certain versions of their JDKs for the PIV. As to your startup problem - instead of running "startup", try running "tomcat run" - this will start Tomcat in the current DOS window instead of spawning a new one and the error will be displayed and persist for you to read and solve. Usually this is either a badly configured TOMCAT/JAVA_HOME or something else is using one of Tomcat's ports (8080 and 8007 by default).

RE: errors displaying graphics
These errors are coming from html pages, or a JSP page in the case of the applet class, with the propper html tags. Some of these images are then displaying correctly under JSP pages.

RE: jsp could not be loaded on winnt
Make sure that your classpath is being set up properly, and that any of your own classes are in a directory that is in your classpath. I had this, but can't remember exactly which thing I had to add to the classpath.

Tomcat 3.2.1. is working fine on our linux boxes, but we also need to setup tomcat on a notebook for demonstrations. The strange thing is, it is not working. We are using Sun's JDK 1.3 and WIN 2K. When trying to access a servlet we get a Null Pointer Exception and when looking at the stack trace it seems to be related to to the class loading (adaptiveClassloader). Is there anyway to start Tomcat in debug mode? I'd like to see what class is missing or whatever reason there is?! Btw. When starting up tomcat right before establishing the handlers it reports that the jsp servlect could not be loaded and displays a count to 357. I have never seen this on Linux?! Any ideas?

how to use JavaDoc with ANT?
What is ANT supposed to do with the creation of JavaDocs. Is it creating them from the java files, or is it expecting them to be there. I have an application that builds correctly, but doesn't have any JavaDocs created, and ANT appears to load my Build.bat file, and generate a bunch of errors. How can I set this up to actually created to documentation.

how to write servlet to use multiple contexts
The servlets and JSP pages that I have written all work fine if I have it running under the webapps/ROOT context. I would also like to have another version running that I can modify, running in webapps/test. I have set up the contexts, but because the url's in the jsp pages all point to "/myservlet", it always runs from the webapps/ROOT context, even if it was called from a html page under webapps/test that I got to from www.my.server/test/index.html. Do I have to code something in the jsp pages to make them context aware?

Is that the only way? I understand how that would be implemented, but I have inherited an application that was not set up that way, and would require a fix on every JSP and servlet.

how to USE differnet contexts
I have set up two contexts. One runs from webapps/ROOT, the other from webapps/test. The contexts appear to be set up correctly. My application runs fine from webapps/ROOT. The problem is running from webapps/test. The main servlet calls JSP pages, which redirect to the main servlet again. The JSP pages just reference /myServlet. They do not specify a context, such as test/mysServlet, or ROOT/myServlet. I don't want to have to change every JSP page to run this application in a different context. What do I need to do this, so context is independent?

JSP pages in webapps/ROOT will not 'recompile'
I am trying to run an application in ROOT, and have changed several JSP pages to look at a different images directory, but none of them have actually changed. I noticed that there is no context for ROOT in server.xml, which is where I thought that maybe the reloadable=false was set. Any ideas?
