Re: ClassCastException uppon requests

Re: Conflict between tomcat 3.2 libraries and application libs
Upgrading to tomcat 4 (or maybe 3.3 as well, I'm not sure what it does with classpath tho) would do the trick, but I'm not sure if that is an option.

Which ISAPI_REDIRECT.DLL to use for Tomcat 4.0.1 w/ IIS 5?
Hi! I've just installed Tomcat 4.0.1 on W2k and it works. Next step would be the installation of the ISAPI_REDIRECT.DLL to serve HTML-pages and stuff via IIS 5. But in contrast to Tomcat 3.2.3 there is no dedicated ISAPI_REDIRECT.DLL-file that comes with version 4.0.1. Question: Can I (should I) use the old .DLL-file or is a Tomat-4-ready-version on its way? And: If I am to use the old version - where do I put the uriworkermap.properties file? There is none in the conf directory of Tomcat 4. bestWISHES Ingo

Using a servlet for authorization
I am trying to use a servlet for authorization like this: There is a servlet called authservlet which checks to see if there is a valid user object in the session state. Here is how it is used: I have a directory called /secure with a bunch of .jsp files in it. There is a mapping in web.xml: servlet-mapping servlet-name authservlet /servlet-name url-pattern /secure/* /url-pattern /servlet-mapping Every time someone tries to request a page like /secure/hello.jsp, the request is instead handed to authservlet. That part is working fine. authservlet gets the request and can decide what to do with it. The problem is that I am trying to get authservlet to pass the request back to the jsp by doing something like this: RequestDispatcher rd = request.getRequestDispatcher(/secure/hello.jsp); rd.forward(request, response); where in this case I have hard-coded in hello.jsp as the target, just for testing (obviously I will replace this with something which looks at what the real url is). The problem is, when I then try to load /secure/hello.jsp, it looks like the server goes into an infinite loop. It never returns the page and I end up with a bunch of catalina processes running, which I have to kill -9 to get rid of. I'm sure I'm making some simple mistake here. Any sugestions? Thanks

Important: RE: [TC3.3b1](=? TC3.3rc1) use of taglib causes org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found error
I have the same problem, but I'm just using raw JSPs, no Jetspeed or
anything.
Further, I thought that Tomcat 3.3 (later builds) was supposed to solve the
problems with
mixed XML parsers. The problem I get is when a JSP includes some other
JSP via jsp:include. What ~seems~ to be happening is that the included
JSP
gets compiled using the ClassLoader of the WebApp rather than Tomcat's
ClassLoader
so that if the XML parser you're using is incompatible there'll be a
problem.
Is there a Tomcat developer out there who can help?
Thanks a lot,

Subject: Re: [TC3.3b1] use of taglib causes
org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found error
I have made the changes suggested. I still get the same errors.
The jsp file will work when referenced directly,
http://localhost/jetspeed/hello.jsp, but fails when it is executed by
Jetspeed.
This problem is does not occur in Tomcat 3.3-m4 or Tomcat 4.0-b7. I
suspect something that was changed between 3.3-m4 and 3.3-b1
is causing
the problem, but I do not know what it is :-(. I do not believe the
problem is with Jetspeed because I used the same WAR file when testing
all 3 versions of Tomcat.
The error message may not be related to the actual error. The empty
.java file in the work directory may be the closer to the problem.
Maybe somewhere in the process of converting from .jsp to .java when a
taglib is defined.
I enabled debug logging.

Figured it out (was Re: Using a servlet for authorization)
This... servlet-mapping servlet-name authservlet /servlet-name url-pattern /secure/* /url-pattern /servlet-mapping and this RequestDispatcher rd = request.getRequestDispatcher(/secure/hello.jsp); rd.forward(request, response); were causing a horrible loop. I didn't realize that Tomcat would run the servlet mappings on the args to getRequestDispatcher, but it does. The solution is simple: make the url-pattern something else, like securepages, and then it can serve the files out of the /secure/ directory. This is going to be a fantasticly useful auth method once I get it all working. Yet again, I find that tomcat is enormously powerful and has a steep learning curve. The two go together I guess.

RE: blocking access using filter
Thanks, Craig!
1. If user is not logged in or if the session has
timed out then it should open login page and after
successful login it should try to access the very
same request (ie. the same document).
I don't quite see why you need to modify the standard
form-based login mechanisms, either. Can't you just use
the standard form based login for triggering authentication?
No, I did not want to modify standard login mechanism by
any means :-). I simply had this (wrong) impression that
filters get called before checking security constraints.
How stupid of me :-). Creating security constraint like
you suggested covered the first step and now I have this
filter purring like a kitten.
Just in case anybody is interested... this is what I did.
doFilter looks like this:
public void doFilter (
ServletRequest request,
ServletResponse response,
FilterChain chain
)
throws IOException, ServletException
{
HttpServletRequest httpRequest = null;
HttpServletResponse httpResponse = null;
if( request instanceof HttpServletRequest )
httpRequest = (HttpServletRequest)request;
if( response instanceof HttpServletResponse )
httpResponse = (HttpServletResponse)response;
boolean authorized = false;
String user = httpRequest.getRemoteUser();
// Is this really necessary? Could it be that requests
// other than HttpServletRequest are passed to
// this filter? Can they be harmful by any means?
// Or should I let them through?
if( httpRequest == null || httpResponse == null || user == null
){
httpResponse.sendError( HttpServletResponse.SC_NOT_FOUND
);
return;
}
try {
// At this point we have user name in 'user' and request
URI
// in 'requestURI'. Make sure that this user has rights
to
// get this document and set authorized to true, if
(s)he has.
authorized = ...
} catch( Exception e ){
}
if( !authorized ){

}

Re: Reversed deployment configuration for mod_webapp...
Pier Fumagalli wrote: I've been looking in the past month at which were the main difficulties in mod_webapp usage, and I think that the most difficult part for users comes when someone tries to deploy a web-application both in server.xml and httpd.conf.

BUT (yeah, there's always a but), what's going to happen is that when run, we're going to have TWO instances of the examples context: one deployed for the localhost host (configured in server.xml) and one configured for myhost.domain.dom (configured in httpd.conf and autodeployed by WARP). Basically, if you're not careful enough, things are going to be screwed up, and you won't get what you want. - Sure I have tried to help several time in user list about this... One possible solution to the problem would be to reverse the deployment scheme of WARP. If we put all context configurations in server.xml, and add a directive such as WebAppDeployAll true, what we can achieve is that for a particular VirtualHost... or root the root server configured in httpd.conf, we're going to automatically retrieve all contexts configured in server.xml for that particular host. Like JkAutoMount * myworker1 * (in a VirtualHost.../). This will solve a bunch of problems, but there is one tiny little bit that is still lacking from Catalina, and that makes things hard: apache, and all other webservers, use the Host header to select what named virtual host I'm using. The Host header, though, is formatted in this way: host:port. So, what it basically means is that a virtual host name is made up by two values: the name and the port. Catalina standalone works great, because I can just set up two connectors in two engines, with two different ports, and have different behaviours for two virtual hosts having the same name but different port values. When coming down to WARP, we have one single connector getting all requests thru one single port, so, what we need to do is use a selector also over on a port to figure out the real virtualhost (host:port) to use. What about using host_port (or any character is not valid in hostname)? When I try to add server localhost_8080 J2EE gives a funny error message Cannot connect to host. I'm planning to implement this mapping in the Warp* classes (not to break anything back), basically rewriting the map methods and adding a setPort/getPort property into host. But by doing this I won't be able to use the Standard* implementation of the Catalina stuff... My only problem is how this could cope with the Manager Application. Specialy how to detect that sometime has changed? Pier

Asunto: Important: RE: [TC3.3b1](=? TC3.3rc1) use of taglib causes
org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found error
I have the same problem, but I'm just using raw JSPs, no Jetspeed or
anything.
Further, I thought that Tomcat 3.3 (later builds) was
supposed to solve the
problems with
mixed XML parsers. The problem I get is when a JSP includes
some other
JSP via jsp:include. What ~seems~ to be happening is that
the included
JSP
gets compiled using the ClassLoader of the WebApp rather than Tomcat's
ClassLoader
so that if the XML parser you're using is incompatible there'll be a
problem.
Is there a Tomcat developer out there who can help?
Thanks a lot,
Huw

Subject: Re: [TC3.3b1] use of taglib causes
org.apache.crimson.jaxp.DocumentBuilderFactoryImpl not found error
I have made the changes suggested. I still get the same errors.
The jsp file will work when referenced directly,
http://localhost/jetspeed/hello.jsp, but fails when it is
executed by
Jetspeed.
This problem is does not occur in Tomcat 3.3-m4 or Tomcat 4.0-b7. I
suspect something that was changed between 3.3-m4 and 3.3-b1
is causing
the problem, but I do not know what it is :-(. I do not believe the
problem is with Jetspeed because I used the same WAR file
when testing
all 3 versions of Tomcat.
The error message may not be related to the actual error. The empty
.java file in the work directory may be the closer to the problem.
Maybe somewhere in the process of converting from .jsp to
.java when a
taglib is defined.
I enabled debug logging.

I know it's a kludge, but AFAICT, these sorts of

RE: How to change session key name
Did my simple test on Tomcat 3.1 and yep, no

You will need to upgrade to avoid this bug.
There are a lot of other bugs you would avoid by
upgrading as well.

RE: running multiple instances of the same web app with an application-scope javabean
You could try running the same webapp multiple times on one Tomcat instance using different context names for each webapp instance, i.e. Context path=/myapp1 docBase=myapp ...

Unfortunately, this web app uses a bean with an application session context. This bean should be though different for each web app instance deployed on the server. I have a few ideas how this could be achieved, but am not sure if they're realistic: 1. Somehow force Tomcat to run multiple JVM. If this is possible, how I can instruct it to run a single web app instance on a given JVM? 2. Install multiple instances of Tomcat on the same machine and run a single web app instance in each installation. 3. Change the bean scope to session, introduce a new init servlet whose session starts with the server startup and ends with the server shutdown, and share the bean among servlets/JSPs within the same context. Is this feasible, and is there a better solution? thx Alex

JAAS not working any more with Tomcat 4.0 (!?)
Hi all,
when trying to perfom a JAAS authentification from within servlets I
get the attached error message. Funny enough the same code works with
Tomcat 3.2.x but not with Tomcat 4.0! The code snippet I use for the
authentification is:
/* set the path to the jaas configuration files */
System.setProperty(java.security.auth.login.config, jaasConfigFile);
[...]
LoginContext lc = null;
try {
lc = new LoginContext(sampleJAAS, new MyCallBackHandler());
} catch (LoginException le) {
le.printStackTrace();
/* ... auth failed */
} catch (SecurityException se) {
se.printStackTrace();
/* ... auth failed */
}
As mentioned before the same code works with Tomcat 3.2.x and when used
standalone. The path to the config file is correct (I even put it in
different locations within the classpath and working directories). I am
not using a security manager. I use a simple NT login module, however it
is never invoked (the exception is raised before). All other parts of the
application is working quite fine. Am I doing something?
Any help will be greatly appreciated.
Kind regards,

I'm not sure how far this helps. But try flush() every time
you write bytes
to outputstream.
Even though u r loosing the advantage of BufferStream by
flushing every
time, there is a chance that u'll get an IOException if the
user cancels the
download and the IOStream is closed, as the flush() forces
the bytes to the
end stream.

I am using a servlet to serve a large file (50MB) and
everything works
fine
if it completes as requested. But if the user clicks 'cancel', I get
different results from Tomcat. Sometimes the servlet stops
running where
it
is, as if the thread is interrupted, while other times it continues
running
like nothing happened. In the both cases the download box
disappears from
the browser. Netscape 6.1,4.7 and IE 5.5 all act the same
way. (IE 5.0 has
a
problem here, but I have other problems with it too).
here's the code in my servlet providing the file
resp.setContentType(application/octet-stream; name=somefile.exe;);
resp.setHeader(Content-Disposition,
attachment;filename=somefile.exe;);
resp.setHeader(Content-Length, String.valueOf(filelength) + ;);

RE: cancelled request
my problem is that I can't distinguish a valid request from a cancelled one.
Tomcat in some instances stops my servlet exeution and in others lets it go
as if I didn't cancel.
There doesn't seem to be a time difference between downloading 50MB and the
time it would have taken to complete the download had I not clicked
'cancel'.
I would have expected the socket to be closed and an IO exception to be
thrown in my servlet - but if the servlet just stops as it sometimes does,
that's ok too.

There is a mapping in web.xml: servlet-mapping servlet-name authservlet /servlet-name url-pattern /secure/* /url-pattern /servlet-mapping Every time someone tries to request a page like /secure/hello.jsp, the request is instead handed to authservlet.

The problem is, when I then try to load /secure/hello.jsp, it looks like the server goes into an infinite loop. It never returns the page and I end up with a bunch of catalina processes running, which I have to kill -9 to get rid of. It's not the server that went into a loop -- it's your application. The request dispatcher mechanism uses the same servlet mappings that are used on the original request. Therefore, the request dispatcher for /secure/hello.jsp will select your authentication servlet again, which will get another request dispatcher, which will ... The solution to this problem, at least in a Servlet 2.3 environment (like Tomcat 4), is to use a Filter for performing this kind of authentication.

RE: cancelled request(more info)

[jk_ajp12_worker.c (596)]: ajpv12_handle_response, error writing back to

But then at the time that the download would have completed, I get the
following in the log(no more 'write' messages in between)
[jk_ajp12_worker.c (590)]: ajpv12_handle_response, response body is done
[jk_ajp12_worker.c (602)]: ajpv12_handle_response done

[jk_ajp12_worker.c (163)]: Into jk_endpoint_t::done
Does the isapi filter within IIS notify Tomcat that it gets this error? It
doesn't appear to be sending the error back to tomcat.
Or could it be that since I am writing so much to the output stream that
tomcat does not get the opportuninty to check for errors after it sends data
to the isapi filter?

my problem is that I can't distinguish a valid request from a

Tomcat in some instances stops my servlet exeution and in
others lets it go
as if I didn't cancel.
There doesn't seem to be a time difference between
downloading 50MB and the
time it would have taken to complete the download had I not clicked
'cancel'.
I would have expected the socket to be closed and an IO

I didn't see anything about this in the archives, so
hopefully someone can
help me out here.
TC 3.2.1/IIS 5/W2K
I am using a servlet to serve a large file (50MB) and
everything works
fine
if it completes as requested. But if the user clicks
'cancel', I get
different results from Tomcat. Sometimes the servlet stops
running where
it
is, as if the thread is interrupted, while other times it
continues
running
like nothing happened. In the both cases the download box
disappears from
the browser. Netscape 6.1,4.7 and IE 5.5 all act the same
way. (IE 5.0 has
a
problem here, but I have other problems with it too).
here's the code in my servlet providing the file
resp.setContentType(application/octet-stream;
name=somefile.exe;);
resp.setHeader(Content-Disposition,
attachment;filename=somefile.exe;);
resp.setHeader(Content-Length,
String.valueOf(filelength) + ;);
InputStream isDownload;
isDownload = getServletContext().getResourceAsStream(filename);
BufferedInputStream bisDownload = new
BufferedInputStream(isDownload,2048);
BufferedOutputStream bosDownload = new
BufferedOutputStream(resp.getOutputStream());
byte[] buff = new byte[2048];
int bytesRead;
while(-1 != (bytesRead = bisDownload.read(buff, 0, buff.length)))
{
bosDownload.write(buff, 0, bytesRead);
}
bosDownload.close();
bisDownload.close();
The reason that this is an issue is that I send an email
upon completion
of
this download, and it shouldn't be sent if the user clicks
'cancel' but it
is being sent when the servlet continues processing. I've
also wrapped
this
code is a try/catch and no exception/error is ever thrown.

Catalina as an NT Service
I've seen several queries about running Catalina as an NT service but didn't find any clear replies, at least regarding using the jk_nt_service.exe. I got it working, but it was all pure guesswork. Maybe someone who knows something about this can add some information or, BETTER STILL, add some information to Catalina about running it as an NT service. I started with the directions for Tomcat 3.2 and jk_nt_service.exe http://jakarta.apache.org/tomcat/tomcat-3.2-doc/NT-Service-howto.html I made the following additions/changes to wrapper.properties: The only thing I found I needed in the classpath was bootstrap.jar: wrapper.class_path=$(wrapper.tomcat_home)\bin\bootstrap.jar The startup class is different: wrapper.startup_class=org.apache.catalina.startup.Bootstrap I added some flags and other changes to the startup command. I didn't test to see if these are really all needed. The SAXParser one is probably only needed if your app uses it and you don't explicitly name the parser class. The -Xrs switch is probably only needed for JDK 1.3.1 to keep the service from dying (??) Note the start on the end. Broken across multiple lines here for clarity: wrapper.cmd_line=$(wrapper.javabin) -Xrs -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser -Dcatalina.home=C:\jakarta-tomcat-4.0-rc2 -classpath $(wrapper.class_path) $(wrapper.startup_class) -config $(wrapper.server_xml) start Frank Lawlor Athens Group, Inc.

RE: j_security_check
Hi, I assume you are running a web server in front of tomcat in which case you need to tell your web server to delegate handling of j_security_check to tomcat. With apache you would add following to httpd.conf JkMount /login/j_security_check ajp13 (or ajp12 depending on connector protocol you are using) Hope this helps andrew On 18-Oct-2001 Wayne Hefner wrote: I am trying to set up a form based authorization, I have done everything similar to examples I have found.

RE: How to change Tomcat default port from 8080 to standard port 80?
You must change the port number in server.xml. However you will need to run Tomcat as root to bind to this port. I don't think you want to run Tomcat as root in a a production environment. As far as I know there is no way to start Tomcat as root initially so that you can bind to that port and then switch the user so that the porcess runs under that user. A solution is to use Apache as the server on port 80 forwarding requests onto Tomcat. Apache lets you switch users after binding to port 80.

Transfer-Encoding in Tomcat
I've been reading the changes from 3.2 to 3.3 and I see that support for transfer-encoding has been added to mod_jk. Does this effect the end browsers at all? It seems to me that the only thing that would use mod_jk would be apache to hand of the request to tomcat. After the jsp is compiled and returned to apache then apache handles all the content transfer stuff back to the browser, am I correct in this assumption? What I'm getting at is some users expierence proxy errors along the lines of incorrectly formatted chunked messages and such. I'm wondering if the problem is related to tomcat, apache, or possibly one of the other afiliate sites that are pulled from the page. thanks, -avery -- Avery Buffington Portal System Administrator FundsXpress Financial Network [EMAIL PROTECTED] Let's call it an accidental feature. --Larry Wall S/MIME Cryptographic Signature

Broken pipe message in tomcat.log
Hi, I'm using Tomcat 3.2 and I get the message: Context log: path=/rpm Broken pipe /rpm/servlet/rpm.Login Context log: path=/rpm Broken pipe /rpm/servlet/rpm.Login Context log: path=/rpm Broken pipe /rpm/servlet/rpm.Login Context log: path=/rpm Broken pipe /rpm/servlet/rpm.Login in my tomcat.log file when I try to access my login servlet. This only happens occasionally and makes tomcat hang. I've read the archives and none of the proposed solutions seem to apply to my situation since I'm not using any connection broker in this servlet. Also each call to the servlet establishes a connection and then disconnects so my problem is not related to a connection timing out due to any servlet inactivity. In addition I've checked during this hang to see if I'm running out of db connections. I'm not. Also what is interesting, If I wait about 2 minutes the servlet will finally connect and let my application continue on is merry way (much to the annoyance of my users) I'm sure others are having this problem or have had this problem and found a solution.

Re: Tc 3.2.3 SSL/HTTPS config
Info on how SSL works is off topic here and there are some very good papers
on the net on the subject. I did a short search with Google (search terms:
SSL encryption protocol) and found a reasonable intro paper from Netsape on
the subject. It's at least enough to get your feet wet.
As far as Tomcat is concerned, I use 4.0.1 and can't authoratatively give you
an answer on the level of SSL encription supported by 3.2.3. The docs should
say so somewhere. I would suggest using the latest stable JDK (not JRE) and
downloading the latest version of JSSE from Sun since it does not come with
JDK 1.3.x. I believe server.xml has instructions on generating a self signed
cert for Tomcat as well.
On Wednesday 17 October 2001 07:19 pm, you wrote:
- Message Text -
Hi All,
I've got an older Tomcat 3.2.2 installation that's apparently fully
functional (haven't tried servlets/JSP yet) and I've just set up a new
Tomcat 3.2.3 installation. Both installations serve their pages just fine.
...I realize that someone might tell me to go talk to another group
regarding these topics but I'm posting here because this audience has to
_use_ these tools whereas these questions would be lost on other groups
(like JRE)...
I'd like to get some more insight related to certificates and encryption
strength:
1) When I connect to my new 3.2.3 installation and have my certificate
read, it reports to the browser that during a Certificate Name Check the
certificate presented does not contain the correct site name. I'd like to
know how to avoid this warning message. I also note that I don't get this
message when I connect to my older 3.2.2 installation, yet the keys were
created (more or less) the same way (see below). Ideas?
2) Additionally, the new 3.2.3 installation reports that it's certificate
uses Export Grade (RC4-Export with 40-bit secret key). After a second
look, so does the older 3.2.2 installation. I'm not too worried about the
encryption of the certificate, but this brought up an interesting question
for which I don't know where to look: what's the actual encryption used
for communications? I'm a Netscape fan, and eschew IE, and for various
reasons I only use Netscape 4.7 - it doesn't tell me what the
communications algorithem or strength is. Any clues where I find this out?
(I saw that Tomcat with JSSE has a LOT of choices...) Does the Tomcat
server automatically pick the highest strength encryption available with
the connecting client? I haven't seen anything on this anywhere and I
have looked... What gets me thinking here is that I downloaded the full
strength US versions in every case. If it's going to only use export 40
bit, what's the point and where's that stronger encryption?
Certificate details: In installing Tomcat 3.2.2 I ran into a bug in that
the certificate generator 'keytool' from the JRE in my environ apparantly
didn't include RSA support. (java version 1.2.2 Solaris VM - build
Solaris_JDK_1.2.2_06, native threads, sunwjit) . So, I loaded version
1.3.1 of the Java2 runtime environment and the keytool from that works
fine. There should be some different flags for specifying what grade
of key gets generated in each case - I haven't found them yet. ...On my
new 3.2.3 installation, I ran the keytool that came with Java 1.3.0. The
certificate served by the 3.2.3 installation reports a bad certificate
name check, and the one from JRE 1.3.1 doesn't...
Minor, unrelated point: ${TOMCAT_HOME}/bin/tomcat.sh doesn't seem
to work properly on my RedHat 6.2 box. On one occasion it crashed the
shell I was in when I accidentally ran start twice. I suppose it
could be unrelated but nothing else died. -shrug- I'm not spending any
time on that one. -smile-

problems with JDBC and JSP
hi All, I'm having some wierd behavior in a JSP that I can't seem to trace the cause to. The code is similar to as follows query = some query PreparedStatement ps = connection.prepareStatement(query); ps.setInt(1, some int variable); ps.setInt(1, some other int variable); ps.executeUpdate(); ps.close(); //second update query2 = new query ps = connection.prepareStatement(query2); ps.setInt(1, some int variablet); ps.executeUpdate(); however after closing the prepared statement the second everything goes smoothly except that only nulls get inserted into the second update. I've checked to make sure that the data gets to the right places before the insert by checking with System.out.println(some int variable) however nothing seems to help. it's as if the second update never occurs. I'm running a win2k server, with tomcat 3.2.3 and a MSSQL server 2000, JDK 1.3 any advice is welcome thanks. -Pete

Bind naming operation failed with JDBC DataSource
I've been trying to get Tomcat 4 and Apache set up to work
together using the mod_webapp connector, and keep running into
this problem that has me stumped. So far there's only one
message here in the users list that's described the same problem,
but it has no accompanying solution. I've checked the docs,
searched the user list archives, looked at the source and tried
several different approaches in search of a solution, to no
avail.
I've set up a JDBC datasource in Tomcat's server.xml file, and
made the appropriate resource-env-ref entries in my
application's web.xml file. What's happening is that when I start
up Tomcat, the log file for my application (/InspSched) shows an
error message as follows:
StandardContext[/InspSched]: Bind naming operation failed :
javax.naming.NamingException: Name {0} is already bound in this
Context
Even with this error, I can still connect to port 8080 and run my
application as expected. Info from the database is displayed as
it should be, which leads me to believe that at least the
datasource is set up properly. However, when I attempt to start
up Apache, Tomcat's apache_log file shows that a
javax.naming.NamingException: cannot create resource instance
exception is thrown. My /InspSched app does not work when called
from Apache, but Tomcat's /examples app works fine.
Here are the context lines from my Tomcat server.xml file:
Context path=/InspSched docBase=InspSched debug=0
reloadable=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=localhost_InspSched_log suffix=.txt timestamp=true

Here are the relevant lines from my application's web.xml file:

/resource-env-ref
And here are the lines from the init() function of the controller
servlet, which is loaded on startup.
Context ctx = null;
try {
ctx = new InitialContext();
} catch (NamingException e) {
log(Couldn't build an initial context);
throw new ServletException(e);
}
try {
PDataSource pds = (PDataSource)
ctx.lookup(java:comp/env/jdbc/InspectionDb);
} catch (NamingException e) {
log(JNDI lookup failed);
throw new ServletException(e);
}
What am I missing? How can I eliminate that first naming
exception that occurs when an object bind attempt is made? How
can I determine exactly what object is being bound? Is this
first exception related to the resource instance exception that
occurs when Apache is started up?
Thanks!

Subject: WebApp: Error 500 (File: pr_warp.c Line: 434)
hi,
I have installed TC4.0.1 and Apache on Win NT.
Connected them using mod_webapp and Warp.
Sometimes nothing comes and browser waits for the output.
But sometimes i am getting the following error.
