problems connecting to MS Access when Tomca3.2 runs as service

2002-03-19 Thread Sampige, Srinivas


Hi

I am running  Tomcat3.2 on Windows2000. I am facing a problem when I try
to connect (from a Servlet) to an MS Access database when Tomcat is running
as an NT service. When I manually run Tomcat from the console the same
servlet works perfectly. The link
http://www.apachelabs.org/tomcat-user/200101.mbox/%3COFB012A4B8.0583C846-ONC
[EMAIL PROTECTED]%3E discusses the problem where the
driver is not getting loaded. But, the error I get is different -

--
SQL EXCEPTION OCCURRED CONNECTING TO DB -[Microsoft][ODBC Microsoft Access
Driver] The Microsoft Jet database engine cannot open the file '(unknown)'.
It is already opened exclusively by another user, or you need permission to
view its data.
--
 so it seems like the drivers are getting loaded. I am unable to figure out
the problem. Any help would be greately appreciated. I looked at the ODBC
data source that I have created but found nothing that is out of place.

thanks
Srinivas

Class.forName() crashing Tomcat4.0

2002-04-11 Thread Sampige, Srinivas


Hi 

   Iam using Tomcat4.0 on Win2K . My web appliation that was connecting
to DB2 was working fine on Tomcat3.2. I am using JDK1.3.1 to compile my
application. But when I port the application to run under Tomcat4.0 the
section of my code that loads the DB2 driver fails and causes Tomcat4.0 to
crash. From the stack trace I identified that the code is failing at line 79
of my class and that line is  where I am loading the driver by calling
Class.forName(). Here is the code snippet followed by the stack trace -

Bug in Tomcat ? - forwarding HTTP request from a Servlet to a JSP

2001-07-17 Thread Sampige, Srinivas


Hi 
 Iam using tomcat 3.2.1 and i have a servlet "PronServlet" that extends from 
HttpServlet . Now i have a servlet "LogonServlet" that extends from servlet 
"PronServlet" (which has got common functionality like checking for a valid session 
;has common methods that perform functionality like forwarding HTTP request to another 
url). In "LogonServlet" i have some code that does some processing and finally 
forwards the HTTP request to a JSP .Iam getting an error which iam pasting below.I ran 
the same application on JRun and it works fine .I noticed that if i removed the 
subclassing and instead subclassed LogonServlet directly from HttpServlet then the 
application works fine by forwarding the request to the next JSP .Here is the console 
output .Iam attaching the source code of
 PronServlet and LogonServlet .Anybody from the Tomcat dev team any ideas. ?

RE: Oracle JDBC in CLASSPATH for Tomcat 4.0

2001-07-17 Thread Sampige, Srinivas

put the zip file under "/lib" folder that you find under your tomcat 
installation.Should work without having to set the classpath because tomcat puts 
everything under /lib in classpath autmoatically when it starts up .

Subject: Oracle JDBC in CLASSPATH for Tomcat 4.0

I am trying to load the Oracle 8.1.7 thin client JDBC driver in a simple
servlet under Tomcat 4.0-b5. However, the following line:

  Class.forName("oracle.jdbc.driver.OracleDriver");

...keeps generating a ClassNotFoundException. I am running on Windows 2000,
and I have verified that the CLASSPATH environment variable is:

  D:\oracle\ora81\jdbc\lib\classes12.zip

...which is where the JDBC driver is. (I can write a stand-alone Java
application that loads that driver just fine, so I know it is where I think
it is.)

For what it's worth, I'm also running under JDK 1.3.1.

Do I have to do something special to have my web app recognize the system
CLASSPATH? Is there some place else I need to explicitly define it?

Many thanks,

Scott

What i told you definitely works at least for the .jar files;from what you say it 
looks like Tomcat isn't picking up .zip files (i personally haven't tried it with .zip 
files).I would leave this question to be anwered by one of the Tomcat Dev Team members 
.But for now what i would try is -

 - edit the tomcat.bat found in the bin folder of the tomcat installation .Here is 
what the first  few lines look like(what is in red is what you need to add) :-

--->
rem - Save Environment Variables That May Change 

set _CP=%CP%
set _TOMCAT_HOME=%TOMCAT_HOME%
set _CLASSPATH=%CLASSPATH%

--->

Modify the last line as -
set _CLASSPATH=%CLASSPATH%;D:\oracle\ora81\jdbc\lib\classes12.zip


 Let me know if this helps.

Can you confirm it is a valid archive ("jar -t classes12.zip")?

Subject: RE: Bug in Tomcat ? - forwarding HTTP request from a Servlet to
a JSP

Hello:

From what I can tell:

(1) In your PronServlet.java service() method, you are manually parsing the
form data using the stream returned by request.getInputStream()
(2) In the JSP page, Tomcat is attempting to parse the form data again.

The servlet API docs specify that you can only call getInputStream() once
on a request, and that doing so may cause problems reading parameters, so I
suspect that's the source of your problem.  I'm not entirely sure why the
generated JSP servlet is trying to read the parameters. Perhaps you're using
the parameters in the JSP page, or perhaps the JSP engine just reads it by
default, which would seem reasonable to me.

The simple workaround would be not to parse the form data in your
PronServlet, but to just use request.getParameter() and let Tomcat handle
it.  That's the way I've done it in the past, and haven't had problems.

Subject: RE: Bug in Tomcat ? - forwarding HTTP request from a Servlet to

Hello:

From what I can tell:

(1) In your PronServlet.java service() method, you are manually parsing the
form data using the stream returned by request.getInputStream()
(2) In the JSP page, Tomcat is attempting to parse the form data again.

The servlet API docs specify that you can only call getInputStream() once
on a request, and that doing so may cause problems reading parameters, so I
suspect that's the source of your problem.  I'm not entirely sure why the
generated JSP servlet is trying to read the parameters. Perhaps you're using
the parameters in the JSP page, or perhaps the JSP engine just reads it by
default, which would seem reasonable to me.

The simple workaround would be not to parse the form data in your
PronServlet, but to just use request.getParameter() and let Tomcat handle
it.  That's the way I've done it in the past, and haven't had problems.

Hi
 Iam using tomcat 3.2.1 and i have a servlet "PronServlet" that extends from
HttpServlet . Now i have a servlet "LogonServlet" that extends from servlet
"PronServlet" (which has got common functionality like checking for a valid
session ;has common methods that perform functionality like forwarding HTTP
request to another url). In "LogonServlet" i have some code that does some
processing and finally forwards the HTTP request to a JSP .Iam getting an
error which iam pasting below.I ran the same application on JRun and it
works fine .I noticed that if i removed the subclassing and instead
subclassed LogonServlet directly from HttpServlet then the application works
fine by forwarding the request to the next JSP .Here is the console output
.Iam attaching the source code of
 PronServlet and LogonServlet .Anybody from the Tomcat dev team any
ideas. ?

RE: JSP's not finding classes in WEB-INF

2001-07-18 Thread Sampige, Srinivas


If you have just .class files then your JSP should work after placing those classes 
under WEB-INF/classes .But if you classes are in a .jar file then place them under 
WEB-INF/lib . Hope this helps

Subject: JSP's not finding classes in WEB-INF 


Greetings!

Ok - running Tomcat 3.2 on SunOS 2.7, with Java 1.2.  

I have a working application with servlets and JSP pages running under
Tomcat 3.1.  I'm trying to port it to 3.2.

However, every time I hit a JSP page, it gives a 500 error about how it
cannot find classes to compile.  Those classes are located in the WEB-INF
directory, under the /classes folder.  

The classpath does *not* contain the WEB-INF/classes directory.

If I hard-code the WEB-INF/classes directory into the classpath, they
work.  However, I do not want to do this.  

What is the problem, and how can I resolve it?

I have tried settiing the environment variables TOMCAT_HOME and JAVA_HOME,
and moving tools.jar into TOMCAT_HOME/lib.

Thanks for any tips or pointers!

Will

Hashtable formData = new Hashtable();
Enumeration en = request.getParameterNames();
System.out.println("===");
while (en.hasMoreElements())

Srinivas:

I can't comment on Jrun or Weblogic, since I haven't used them.  Normally I
figure that since Tomcat is the officially sanctioned reference
implementation, if it doesn't work on Tomcat, it just plain doesn't work,
even if it does work on other containers.

Here's what the servlet API docs say about getParameter in
ServletRequest.getParameter() :
"If the parameter data was sent in the request body, such as occurs with an
HTTP POST request, then reading the body directly via getInputStream() or
getReader() can interfere with the execution of this method."

I take that to mean it may cause problems, but won't necessarily, depending
on the implementation.

Can you try out the workaround I suggested and see if it solves the
problem?  If it doesn't, then we're on the wrong debugging track anyway.

I had something 'similar' happen when I was installing Tomcat 4.0.2...
I could not get servlets in webapps/myapp/web-inf/classes to be found.
I kept changing paths, web/server.xml, etc., but nothing seemed to work.
However, /examples and another WAR file were working fine.
What I did was:
1) I copied the servlets into one of the directories that were working 
(eg. examples).
 The servlets were being found
2) I copied all code from the directory that was not working into the 
/examples directory.
3) renamed the directory to the old nameand all works fine ever since.

Things like this have worked for me in the past when I get REALLY 
frustratedWas I really missing something (doubtful I was misspelling 
the servlet's name in this case)...This is reminiscent of invisible 
characters :-)  ...or something was causing the servlets not to be loaded?!?

Hi Craig
 Craig,my apologies for not being clear . First of all, yes I agree, as you
say - " 99.9% of them being user error or misunderstanding". "The issue"
that I was talking about was migrating to 4.0 from 3.2 as was mentioned in
my email. I spent some time trouble shooting,digging around in the
documentation and discovered that I had to change my "web.xml". 

>answers quickly is to provide as much information as possible about the
>problems you are facing (as *many* people do on TOMCAT-USER):
OS : Windows 2000
App Server : Tomcat4.0
Problem Desc : Servlets that run on 3.2.1 do not run on 4.0. I have added
the context to my webapp in 4.0 in exactly the same manner that I have done
in 3.2.1. 

Erorr that I get :
HTTP Status 404 - /xmlToPdf/servlet/ConvertXmlServlet
The requested resource (/xmlToPdf/servlet/ConvertXmlServlet) is not
available. 

>can tell you if it's been addressed in the documentation.  I'm afraid that
>I cannot read your mind :-).
  Well what was in my mind was ...I was really frustrated that I had to
worry about configuration issues and going back all over again doing trouble
shooting.Should I concentrate on my application design/logic OR should
concentrate on numerous config issues which I had done before and had to do
again when I moved to 4.0 and probably will have to do when I move to higher
versions?? . What I was looking for was some kind of a  guide "migrating to
4.0" which would highlight the kind of problem I faced(is there such a guide
I don't know of?). Also, I personally don't fancy the idea of people
accessing config files directly. Some kind of interface(need not be be fancy
stuff but a simple tool) should be provided. Eventhough everyone of us
understands what a config file looks like and contains it is very easy to
make a mistake but difficult to trouble shoot when involved in a big project
and concentrating on the application logic and other details.(of course
Tomat developers would be able to track down and fix it faster :-) but what
about the rest of us ?).

Thanks for pointing me to the website. But, I have ample experience in
Java,servlets & a host od app servers (and of course packages othwerwise my
complex web app that I am working on wouldn't have worked in the first place
:-)). I guess I need more experience on posting a good email on the "mailing
list". I hope this and my previous email is/was taken in good spirit. I
wasn't looking at finding fault(which is the easiest thing to do :-)). It
was more like a frustrated ...hands in the air..help me ...kind of

Which "this issue" are you speaking of?  If it's the fact that WEB-INF has
to be capitalized, that is documented in the Servlet Specification
(because it is common to all servlet containers, not just Tomcat):

  http://java.sun.com/products/servlet/download.html

In addition, any book or article or tutorial about building web
applications will certainly mention it.

If "this issue" means that you didn't know you have to match your
directory structure under /WEB-INF/classes to the package hierarchy of
your classes, that is fundamental Java programming -- amply covered in the
many books and tutorials about the language itself.  A good place to start
is <http://java.sun.com/docs/books/tutorial/>.
