Re: Easy Servlet Question

[Ben Souther]

I have some demo apps on http://simple.souther.us that you can run.
They're all war files so all you have to do is download to your webapps
directory.

SimpleServlet.war is your basic "Hello, World" app in a servlet.

Easy Servlet Question

[Andrew Pierce]

Hello. I realize this is about the stupidest question I could ask but, 
I've scoured the web, etc. and cannot get an easy example of making 
servlets actually work with Tomcat.


I have written a few "Hello World" servlets and gotten them to work with 
Resin but I cannot get even the most simple servlet to work with Tomcat.


I create the servlet code such as the one found here:

http://www.caucho.com/resin-3.0/servlet/tutorial/helloworld/index.xtp

I compile the servlet and place the .class file in the 
$CATALINA_HOME/webapps//WEB-INF/classes directory.


Then I modify the $CATALINA_HOME/webapps/app/WEB-INF/web.xml to include 
the declarations for the servlet.


I stop and restart Tomcat and alas, all I get is 404 when I try to 
access the servlet with a url like 
http://localhost:8080//HelloServlet.


I know this has got to VERY simple. Thanks in advance.

Yes, I could, but this again didn't explain the behavior which turned out to
be:

Try to create "\images" in a servlet running under Windows Tomcat, it
becomes "C:\tomcat4\webapps\images".

Try to create "/images" in a servlet running under Suze and it becomes
"/images".

I would expect to have to be "/images" in Windows too, except it didn't work
that way. Okay, so Tomcat effects a chroot somehow. But I then expected it

You should read the API spec of java.io.File.
http://java.sun.com/j2se/1.4.2/docs/api/java/io/File.html

If you want to get the absolute path of the application directory
use ServletContext.getRealPath("/"); and pass this to the file

RE: Directory Creation in Servlet Question

[Joe Hertz]

In Windows that's what it means too, but this isn't Windows or Linux...it's
a JVM.

Since it wasn't obvious from the code (MessageResources used in pathnames),
let me put it another way.

The code tries to create a directory /images/.

The Servlet is apparently limited in the filepath it gets to work with. I'd
expect that. 

In Windows, Tomcat executes it and it goes to C:\tomcat4\images\

In my Suze install, Tomcat the analogous directory
/opt/tomcat4/webapps/images

I didn't check to see if it's *different* because in the code it won't be.
It's the same identifier working off of root. Windows Tomcat puts it under
it's webapps tree. I'm expecting Suze to do the same.

I have a hard time imagining that Tomcat gets a different view of its root
file system depending on which OS I runs on. It really ruins the concept of
platform independence for this sort of thing.

you tried to debug it. You can check what is the path before the
directory is created. In Linux / means the root directory and since
the path name begins with File.separator(/), the file is created with
reference to /. For eg. if filePath is /anto. Then if Tomcat have
write permission to root directory the directory will be created.

Directory Creation in Servlet Question

[Joe Hertz]

I have a Struts Servlet that executes the code snippet below to create a
directory.

Under Windows, this works great, the directory showing up under
C:\TOMCAT4\WEBAPPS\

Under Suze Linux, it doesn't get created, and it's not a permission problem.
At least not under the webapps directory. The Tomcat user can definitely
create a directory there (I've su'd to him and done it).

What should I be looking at next?

Re: servlet question

[Bill Barker]

Well, you could try adding in your exception handling:
} catch(Exception e) {
   log("Problem",e);
   // For pre-production debugging only
   throw new ServletException("Problem",e);
}

The way you servlet is at the moment, if you do get an exception, then all
you will see is a blank page with nothing in the logs.

Re: servlet question

[Ernesto Echeverría]

I've seen your code, and your configuration... Everything seems fine
(apparently) but then...

I guess the *.login means you want to be able to
call that from any address in the context, otherwise you might need to write
/*.login instead for the root of the application context.

What about making things simple first? Are you calling the servlet directly
from a browser or from another servlet? How are you invoking it? Are you
feeding the parameters with specific values? What about putting some
hardcoded text in the System.out.println commands so you can really see if
the servlet is being invoked? Do the servlet-examples of tomcat in your
installation work? Is this a particular servlet not working or the first
servlet in this particular application? What about forwarding to the
login_failed.jsp page also it you catch an exception out of the try-catch
block? 

Regards.

By context.xml I meant your 'context' in question, which in this case is
manageit.  So, the context of your manageit.xml should look something like
this:



  



Your URL is something like: localhost:8080\manageit\process.login - correct?

right.
 

However, if you're not using apache, I don't know what to say.  The syntax
looks correct.

Hey all!
I have a servlet called login. I have it mapped in my web.xml as follows:

 login
 org.volume4.authentication.login


 login
 *.login

My WEB-INF structure is as follows
WEB-INF/classes/org/volume4/authentication/login.class
Does anyone have an idea as to why when I call login as process.login
 

from a form it is not run? I have placed some System.out.println(); in

   

there but, it seems that the servlet is not called at all. I basically
just get a blank screen. When I look at the tomcat logs no errors are
recorded here either.

Hey all!
I have a servlet called login. I have it mapped in my web.xml as follows:

   login
   org.volume4.authentication.login


   login
   *.login

My WEB-INF structure is as follows
WEB-INF/classes/org/volume4/authentication/login.class
Does anyone have an idea as to why when I call login as process.login
from a form it is not run? I have placed some System.out.println(); in
there but, it seems that the servlet is not called at all. I basically
just get a blank screen. When I look at the tomcat logs no errors are

RE: Easy /servlet question

[Lee, Paul NYC]

Tomcat 3.x allowed access to servlets under a common mapping (/servlet/*) by
default.  In Tomcat 4.x the developers stopped this behavior by default.
This was done by the invoker servlet.  

To enable this, under $CATALINA_HOME/conf, modify the web.xml file.  Search
for "invoker" and you should find something like this:




Just uncomment and it should work.  Note that "/servlet/" is no longer part
of the specification as of 2.3.  Mapping it is recommended.

RE: Easy /servlet question

[Jérôme Duval]

You must specify your servlet in the web.xml file. This is how Tomcat knows
what to do when you ask it for Upload_CnW. This might be unnecessary to
mention, but you also have to compile your class before launching Tomcat.
Anything else would just be shots in the dark, since you haven't really told
us what you wanted to know and detailed your situation enough.

I use Apache 2.4.9, Tomcat 4.1.9.
In a JSP, there there are three frames in a frameset. the script of each
frame is JSP.
Can a JSP in one frame submit to a Servlet? I did a test and failed. Please
confirm or teach me how to do.
Thanks

Re: invoker servlet question

[Harry Mantheakis]

The Tomcat FAQ has a cautionary note about the invoker servlet:

http://jakarta.apache.org/tomcat/faq/misc.html#evil

> call http://localhost:8080/web_app_context/servlet/

That *should* work, assuming  is the fully qualified name of
the servlet you are trying to invoke. (And assuming everything else is
correct, too.)

> I do not wish to change the web apps WEB.XML
> file just for testing.

Registering and mapping servlets in the deployment descriptor is correct
thing. A servlet is not much use if you do not at least register it - that
allows you to forward requests to it from other servlets. Mapping is
optional: it allows you to invoke the servlet with a URL, which is what a
browser does.

Register a servlet, and call it (say) "Test":


 
Test
 
 
 com.foo.bar.MyNewServlet
 
  

Then specify a convenient mapping:



Test


/test

 

That allows you to invoke MyNewServlet with just '/test' in the URL.

When you want to test another servlet, just replace the fully qualified name
'com.foo.bar.MyNewServlet' to that of the newer servlet.

Good luck..

Re: invoker servlet question

It works for me. To be able to answer you, it would be good to have 
error messages to build the answer on.  this is the only thing that 
comes to mind. You have to have the full class name (with package name) 
to be able to call it, as :

http://localhost/webapp/servlet/com.john.mclain.servletTest

hope it helps

Your servlets need to be in a package.
Then you can call it like...

Howdy,
I'm not sure I understand your question, but there's no such thing as a

matter altogether).

Others have shown how to get the server to initialize on server startup.
What do you mean by "run it all the time"?

What is an application scope servlet ?.
You can ask the container to initialize a servlet at container start up by
setting the   parameter to 1 in web.xml. like this.

RE: servlet question

Howdy,
Whoa, what's going on with this thread? ;)

There's no j2ee.jar with tomcat, there can't and shouldn't be.  Don't
look for it.

You don't need all the classes in commons/lib to compile your servlets,
don't add them all to the classpath.  Add only the ones you need, which
is typically just the servlet-api classes.

Thank you for helping test out tomcat 5 -- please use the latest release
if you can: 5.0.12 will be out in the next couple of days as a beta.

Re: servlet question

[Ben Souther]

In order to compile servlets with javac, you will need to include all of the 
jar files found in ...common/lib in your classpath.   Tomcat will include 
them automatically when it starts up for running the servlets but you will 
need to do set up your environment manually in order to compile with javac.

Remember, each jar file needs to be explicitly added to your classpath. Don't 
just add the directory that they are under.

OT: Download Servlet question

[Atreya Basu]

Hello,

I have a slightly off topic question.

I have a servlet returns a file to a client.  It works for both MSIE and
Mozilla but for Mozilla it adds, '.jsp' to the end of the filename.

I set my headers:
response.setContentType("application/octet-stream");
response.setHeader("Content-Disposition","attachment;
filename="+fname);
response.setHeader("Cache-Control","no-cache");
response.setContentLength(available);

I am of course pre-compiling my JSP.  Any ideas anyone?

Thanks in advance.

Re: servlet question

You need to wrap the request with a wrapper that overrides the getMethod()
method.  Something like:
 class GetWrapper extends HttpServletRequestWrapper {
  public GetWrapper(HttpServletRequest request) {
 super(request);
 }
 public String getMethod() {
 return "GET";
 }
 }

 GetWrapper wrapper = new GetWrapper(request);
 RequestDispatcher rd =
 getServletContext().getRequestDispatcher(direct);
 rd.forward(wrapper, response);

You can't accomplish this using the RequestDispatcher facility. You will have 
to generate a new HTTP request within the servlet and send it to the desired 
destination.

Re: servlet question

[Paul Hsu]

Michael,

If I forward to a servlet, yes I can process the request in second servlet.

Thank you for the help. I think you may misunderstand my question. My
question is how can I forward the request to my next URL and change the
method to 'GET' if the orignal request is using 'POST'.
For example:

test1.html call servlet1 by using "POST" method, but servlet1 need to
forward to servlet2 by using "GET". How can I switch from "POST" to "GET" in
servlet1.

Hi,

I try to forward a HTTP request from my servlet. I am using the following
code.

RequestDispatcher rd =
getServletContext().getRequestDispatcher(direct);
rd.forward(request, response);

I have no problem with code, but I have one issue is how can I change the
request method from "POST" to "GET" before I forward the original request.

I would appreciate any help

Re: servlet question

if your dispatched request is getting problems because of non compatible
types of GET/Post methods at collaborating servlets then at the receiving
end add a dummy method of (Get or Post), whichever is missing, and forward
the processing to the actual method. For example:

protected void doGet(HttpServletRequest req, HttpServletResponse res)
  throws IOException, ServletException
 {
  doPost(req, res);
 }

protected void doPost(HttpServletRequest req, HttpServletResponse res)
  throws IOException, ServletException
{
with full implementation
}

You have to make sure, that the invoker servlet is mapped to /server

This section is commented out in the conf/web.xml.

So you either need to add this line to your server web.xml or your

Wouldn't it be a good idea to activate this mapping by default

Beginner Servlet Question

[Wileynet]

I've been racking my brain for days trying to figure out WHY I cannot
get this servlet to work. Hopefully someone has an idea. Im running
tomcat 4.1 on IIS . From what I've been reading and the directions I'm
following from a WROX book is that you don’t need the web.xml file if
your inside webapps for the browser to see it.

Directory ch03 is inside the webapps dir. Underneath ch03 I have
classes/com/wrox/jsp/ch03/myapp/MyServlet

Wrox tells me to type this into the browser.
http://localhost:8080/ch03/servlet/com.wrox.jsp.ch03.myapp.MyServlet

I didn’t use the (servlet) because I don’t have  a directory servlet and
Im having a hard time figuring out why that needs to be there. 

I also try it with the (servlet) and nothing. 

I put an index page in the ch03 directory and It pulls that up fine. It
just will not find this servlet??? The class path is set , everything
works except for this.

This is the code for the servlet. Am I just set up wrong, Ive been
everywere I RTFM and Im stumped. It SHOULD WORK ! but it does
not.



package com.wrox.jsp.ch03.myapp;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import javax.servlet.ServletException;

public class MyFirstServlet extends HttpServlet {

  public void doGet(HttpServletRequest request, 
HttpServletResponse response) throws
ServletException, 
IOException {
response.setContentType("text/plain");
log("doGet was just called");
PrintWriter out = response.getWriter();
out.println("This is my first Servlet");

If this is in regards to DB Connection Pooling, there are other options available.  
Poolman can be found at sourceforge.com.  You are correct to be concerned about 
creating multiple instances of this GetConnection class.   You can correct this by 
making a call to a static method called getConnection().  Here's an example of reading 
in a properties file and retrieving pooled connections.

one servlet question

[Ashish Kulkarni]

Hi,
I have to write a servlet which will be a base servlet
for all servlets in my applications.
I have a class called GetConnection which gets the
connection from servletcontext depending upon some
parameters in the session, so i have go send
servletcontext, and session to this class.
now the question is should i create the instance of
this class in init method of the servlet or define a
seperate method and create the instance of that class
from doget or dopost method of the child servlet,(this
servlet will extend the base servlet).
i have this doubt because if i  create the instance of
this getconnection class in init method, it will be in
memory for the full life cycle of servlet(i.e. untill
i stop the app server).
so if i extend this base servlet for other 100 child
servlets, then there will be 100 instance of
getconnection for life cycle of servlet.
so am i thinking in the right way???
any suggestions
Ashish

How many instances of a given servlet class will be loaded by Tomcat.  
Just 1 or can many instances be loaded?  What determines this?

Thanks,

[...]


for any Servlet class, only 1 Class-object(of it) will be loaded 
into the ClassLoader of  webapp in witch that Servlet class is in.

for every "Servlet declaritaion", container  will make one(no pool) 
instance. 

no matter you define "Servlet declaritaion" in WEB-INF/web.xml
or not,  the "default" "Servlet declaritaion" will be always there. i.e.:
- if you define 0 "Servlet declaritaion", there will be 1 instance
- if you define m "Servlet declaritaion", there will be m+1 instance(s)

hope it is right//haha :-)

RE: default servlet question

[Saurabh Shukla]

yeah write a servlet and load it at startup as the first servlet to be
loaded.(for doing thing you need to add an entry in the web.xml). So if the
request is passed to tomcat from apache, it will be handled by your default
servlet.

I do not know if you can invoke a servlet for ONLY 1 URI not for other
requests which r coming to tomcat.

hth,
Shuklix

Hi,

Is it easy with Tomcat to specify that I want a single servlet to serve
EVERY request for a URI?

I.e.  what happens if I have a DefaultServlet which acts as a router for
requests, and I have a few other servlets which serve their own requests,
can I ensure that all requests not meant for any servlet get routed first
to the DefaultServlet?

Does this work for *.jsp as well as *.html as well as *.pdf?

Thanks,

That is not what really happens.  Instead, a single instance of your
servlet is called multiple times simultaneously, on multiple processing
threads.

The maximum is determined by how many threads you configure in the
container's setup configuration, and is ultimately limited by how many
threads your JDK and operating system can support.

Hi,

When a client make a request to a server and a servlet get call,
the servlet then create an instance for that client.
My question is, how many clients can a servlet handle.

Newbie Servlet Question

[Sean McTigue]

I am currently running iTools on MacOSX with the iTools version of Tomcat.
When I place a .jsp file in /webapps/ROOT and place my bean classes in
/webapps/ROOT/WEB-INF/classes, I can run the jsp from //localhost/.jsp.
Works great, however, I cannot figure out how to call a servlet via URL that
is placed in the same classes folder. Sorry for the basic question. Thanks
in advance.

Stupid servlet question of the day

[Bolt, Dave]

Title: Stupid servlet question of the day





This is really a rather embarrasing question to ask.


I have a webapp that has two directories of JSPs 
(think of it as a regular user set of JSPs and an
 administrator set)


\forums   <--- This is the context root
\forums\admin <--- This is a second set of JSPs available
   only to administrators


I have a servlet that I have mapped to the url-pattern 
/postpaper. As shown below.



    WhitepaperUpload
    sample.WhitepaperUploadServlet




    WhitepaperUpload
    /postpaper



If I hit the servlet from any JSP in the directory on the context
root it works fine. If I try to hit the servlet from a JSP in the
admin subdirectory of the context, it does not find the servlet.


Typing the URL http://localhost:8080/forums/postpaper causes the
servlet to run (I see a message printed by the init and get callbacks)


So, if I am in a JSP that is in a subdirectory off of the context root
(in this case \forums\admin\somejsp.jsp) and I want to write a FORM
ACTION to hit this servlet's POST. Should I write


 ...  


I've tried the following


action="postpaper"
action="/postpaper"
action="./postpaper"
action="/forums/postpaper"
action="/forums/admin/postpaper"


and several other variations, to no avail. Any ideas?


Thanks
