RE: web.xml layout

[CPC Livelink Admin]

I believe that the web.xml is parsed using the DTD, so rearranging the
elements will make it complain that the format of the file is incorrect.
Even if you find a container which lets you rearrange, the spec says you
should follow the DTD. So to be portable . . . .

Paul

Does anyone know if it makes any difference whether I group
servlet contexts with servlet mappings or keep all contexts
together and below them keep all mappings together.

Assuming the xml file is being processed by SAX, the
callback handling would make this irrelevant I would think.

Thoughts?

RE: Why does Internet Explorer think it is offline?

[CPC Livelink Admin]

I have found that IE really wants to have the HTTP:// in front of the
localhost - On mine, it wants to change localhost:8080/whatever to
local:8080/whatever and I get a similar error to what you mention.

Could this be part of your problem?

I am using tomcat with IE and am having problems with it.
Every time I start IE and try and access a Java Server Page or
servlet through "lolcalhost:8080/examples/jsp" the browser first complains
that the system is not connected to a network. I then click on
"try again" and the browser then seems to find the JSPand display it.
Is there a special setting for tomcat if the system is connected to a
hub?

Any thoughts?

RE: [ERROR] OutputStream is already being used for this request

[CPC Livelink Admin]

Why do you need to use a JSP - The JSP is designed to product HTML output,
and as such will always grab the writer and set the content type to
text/html.

What is wrong with just using the servlet, perhaps with an extention mapping

RE: Detect Browser "Disconnect"

[CPC Livelink Admin]

Put a heartbeat on the client - Use either an applet or a form with a
timeout before it resubmits.  If you don't get the heartbeat at the server,
than terminate the background thread. (This assumes that the initiat
processing can be put in a background thread.)

WebLogic (sometimes) throws exceptions when you write to the response socket
(out.println) after a user has clicked on the 'stop' button or the browser

RE: Wierd Casting Problem. Tomocat Bug?

[CPC Livelink Admin]

Are any of the classes you are using defined outside of the web app.  That
is, are you using any libraries, or class files which you specify on the
classpath prior to tomcat starting, which may also be in your web-app.  It
is situations like this which the more experienced folks point to as the
cause to this problem.  Generally, the type of error you are mentioning
happen if the class is loaded by a higher level class loader than the
JSP/Servlet's loader, but the JSP/Servlet sees the web-app's WEB-INF class
and libs before the system's classes and libs.  So if the object was created
by the system class loader (with it's copy of the class), it has a different
'Class ID' than one loaded by the JSP/Servlet class loader.

In short, try to remove all elements from your class path and extentions
directories, and put them all in the webapp for a short testing period. See
if this exposes solves the error or exposes a place where some code would
get a class from a different class loader than from others.  Then you can
slowly move the libraries back where they came from to better isolate your
problem.

Hope that helps,
Paul

I found out the problem.  This looks like an extreme hack though.

<$=((member) ((Object)e.nextElement()) ).getFname()%>

Works.   But why do I have to cast to an Object before I cast it back to
it's appropiate type.   My only guess is that the Servlet DownCast the
Vector to an Object (because there is some reflection that goes on) before
setting the Attribute and passing it to JSP.
But the actual member objects are put in the Vector as member Objects.
Any Ideas?  Does anyone thing it's wierd that you have to cast to and Object
then to the Type.
I believe this isn't a Java Bug it may be a Tomcat Bug.  Because I don't
have to cast to an Object, if I am casting to member objects in the Servlet.

Ok.  Here is the problem.  I am using Model 2 Architecture.  So my Servlet
handles all the biz logic and pushes the results that are then displayed by
jsp pages.

Within a jsp page I grab my vector from the request like so..

Vector mems =(Vector)request.getAttribute("response");

Then I try to loop around it and cast it to the appropiate 
Object. Like
so...
<%
for (int i=0; i < mems.size(); i++) {

member m = (member)mems.get(i);
%>
<%=m.getFname()%>
<%}%>


I get a ClassCastException.   But when I do a toString on the Object
itself without casting, it specifies the package name of the object that I
am trying to cast to.

To make matters wierder.  When I do a getClass().isInstance(THE OBJECT 
I
WANT TO CAST TO) it returns false?

What is going on here?  Is this some classLoader issue?


Some tips that might help figure this issue out..

I am importing the class I am casting, in the JSP page. like 
so..

<%@page import="thepackage.member, java.util.*"%>

And the class itself isn't in a jar.  It's in the 
WEB-INF/classes
directory.

I also changed the container from a Vector to an ArrayList and 
got the
same results.

And I can instantiate the member object itself and use it in 
the jsp
page.

Any ideas?  Please.  Someone, HELP!!!

You are getting "Compiled Code" because the JIT engine has compiled
your code into machine native format and it can't trace back to a line of
.java code.  I thought there was a command line option like -nojit, but
checking just now I can't seem to remember how to figure it out.

There are two common ways to find out where your problem is:
1.  Add lots of println statements (you error is in the doGet
method, so hopefully that method just calls lots of other methods and its
code isn't to long)
2.  Run Tomcat in a debugger (its Java so it can be done, but its
very slow)

Thanks for the reply. Is this the same as adding the following lines to
TomcatConf.xml?

  



Or, do I have to set up another context in server.xml? (the above works fine
for everthing except reloading servlets without restarting tomcat. It
doesn't make sense to have to duplicate the context definition.)

RE: HTTP Referer Field Not Appearing

[CPC Livelink Admin]

On 3.2.1 it works for me.  Make sure you are actually getting to the page
using a method which would generate a referrer. Just typing the link in the
browser address bar will not do it.  You need to make a dummy html file with
a link to your test page and click on the link to see it.

Hi All,

For some reason I can't get the Referer header field from any of my JSP
pages. I'm using the following code:

String strReferringURL = request.getHeader( "referer" ) ;

I also tried looking at all of the headers in the request, but it doesn't
look like this is including all of the headers:

for (Enumeration e = request.getHeaderNames() ; e.hasMoreElements() ;) {
  Log.getInstance().logError( (String) e.nextElement() );
}


Is this because my browser is not sending all of the fields (including
referrer), or could it be the way that I have Tomcat configured?

Thanks!

RE: URGENT - Session stickyness lost with cookies disabled

[CPC Livelink Admin]

They are exclusive.  Basically, for every link back into the web application
that needs to maintain session, the programmer must call and EncodeURL
function so that tomcat can add the JSESSIONID parameter to the URL at
execution time.

Apache URL rewriting allows the server to 'adjust' the incoming URL so that
it goes somewhere else.

What about the rewrite mod in Apache? Are the two

Importance: High


Hi!

I'm trying to call a servlet with SOAP over Tomcat via the IIS redirector
(isapi_redirect.dll) but I always got a SOAP Exception (SOAPException =
SOAP-ENV:Protocol, Unsupported response content type "text/html")

I just followed the steps to configure the IIS redirector to work with
Tomcat (
http://jakarta.apache.org/tomcat/jakarta-tomcat/src/doc/tomcat-iis-howto.htm
l ), and I tested calling the /examples directory via IIS with success.

Then I configure the "soap" context (/soap/*=ajp12) in
uriworkermap.propeties, and I modify the java client to access the rpcrouter
via IIS and I always got the SOAPException.

If I access the servlet directly with Tomcat it works just fine. I'm using
the Exchange servlet and java client test examples provided by
http://www-106.ibm.com/developerworks/library/ws-peer2/?dwzone=ws

My configuration consists of:
- Tomcat 3.2.1
- Xerces 1.3.0
- JavaBeans Activation Framework 1.0.1
- JavaMail 1.2
- Soap 2.1

After finishing the installation I deployed the Exchange.java servlet and
test it successfully (Tomcat) with the java client example of the above web
page.

Any advice from or link where I can configure SOAP with Tomcat via IIS will
be greatly appreciated.

Thanks in advance,

RE: Session timeouts

[CPC Livelink Admin]

You could track the ValueBound event, and at binding time, make local
references to the session objects you are interested in. Then when you are
unbound, you do not need to worry about the order, since you have a local
reference and can still get/change information on it.

Yep, I do implement HttpSessionBindingListener and no I can't call
invalidate because I depend on other objects bound to the session within my
session tracker and invalidate does not define the order at which it will
unbind objects.  Therefore I need to do an explicit removeAttribute call so
that I am assured the rest of the objects I need are still within the
session.

For reference here is my code

import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;
import edu.vt.ward.lexus.portal.User.*;

public class SessionTracker implements HttpSessionBindingListener{

 private String userPid;
 private ServletContext context;
 private Hashtable currentSessions;

 public SessionTracker (ServletContext ctx){
 context = ctx;
 }

 public void valueBound(HttpSessionBindingEvent event) {
 HttpSession session = event.getSession();
 User user = (User) session.getAttribute("user");
 userPid = user.getPid();
 String totalLogins;

 if(context.getAttribute("currentSessions") == null){
 currentSessions = new Hashtable();

 Date uptime = new Date(System.currentTimeMillis());
 context.setAttribute("uptime", uptime);

 totalLogins = "0";
 }else{
 currentSessions = (Hashtable)
context.getAttribute("currentSessions");
 totalLogins = (String)
context.getAttribute("totalLogins");
 }
 Date creationTime = new Date(session.getCreationTime());

 currentSessions.put(userPid, creationTime);
 context.setAttribute("currentSessions", currentSessions);

 int logins = Integer.parseInt(totalLogins) + 1;
 totalLogins = Integer.toString(logins);
 context.setAttribute("totalLogins", totalLogins);
 }

 public void valueUnbound(HttpSessionBindingEvent event) {
 HttpSession session = event.getSession();
 User user = (User) session.getAttribute("user");
 userPid = user.getPid();

 Hashtable currentSession = (Hashtable)

RE: static reference to a method

[CPC Livelink Admin]

The problem is that you have not declared the method as static.  So you need
to either do this :

(new dynamicContent.dynamicContent()).getSelected("A", "B");

or declare the function as static String getSelected(string a, String b) and
call

dynamicContent.dynamicContent.getSelected("A", "B");

If the function is not declared static, then you have to have an object of
the class to call the function.

Hi there
I was wondering if anybody could help me out with
something?

I have a JSP that is trying to access a method in a
java class that I have defined. However, when I try
and run the pgae, it gives the 500 error message and
says

"Can't make static reference to method
java.lang.String getSelected(java.lang.String,
java.lang.String) in class
dynamicContent.dynamicContent."

I have not declared the method as static nor the
class.

The method is part of an error handling page (called
retry.jsp) that is shown to the user when they have
entered data incorrectly in a form. Its function is to
preselect an option (by returing the word SELECTED) in
a HTML select box (the one that the user entered in
the first place) by comparing the value that was
entered by the user in the original input form to the
value of the select box options as they are created
(they are dynamically created, not HTML coded).

RE: Closing ResultSet and Statement?

[CPC Livelink Admin]

ResultSets can and should be closed. They are not like normal classes with
an iterator.

ResultSets are created by Statements. Statements can and should be closed.
When a statement is reused, it will close the resultset (if not closed
already) that it previously supplied in order to get the new results. When a
statement is closed it will close the resultset it created. The number of
simultaneous open statements for a given connection can be (and is)
limited - the oracle limit is about 50 by default.

Statements are created by Connections. If you close the connection it closes
the statement which closes the resultset.

Paul

I'm not sure, but I think that you don't close a ResultSet, you only close

Think of ResultSet like a normal class with an interator that allows you to
go forward and backward.

Well, there are two errors.  One, you don't have the java compiler in your

Second, the XML tag extentions are case sensitive.  You will need to use

RE: Anybody doing doPost successfully ?

[CPC Livelink Admin]

I have 
successfully received post data in a JSP both using the getParameter and using 
the com.oreilly.servlet utility classes. 
 
How 
are you sending the post data?  Are you using a web browser and form, or 
are you trying to post it yourself using an applet or something.  The 
process does work, so it must be something unique to the way you are sending the 
info.

Paul

RE: RequestDispatcher.forward() in Tomcat 3.2.1

[CPC Livelink Admin]

What Craig meant (I believe) by "prohibits you from modifying the response"
is that the response has been committed and no more data can be sent. The
html/other-data you are sending to the client is part of the response. When
the forward returns, you are prohibited by the spec, from adding any more
information to the response output stream.

If you need to do as you desire, you must use some kind of include based
scheme instead of forward.

Regards,
Paul

You are right.  Control does return to the calling servlet.  It just
couldn't
write to the response.  It would be nice if an exception was thrown.

After control returns to the calling servlet, I try forwarding to a second
servlet and that doesn't seem to work.  The first servlet that was forwarded
to did not change the response.

Is multiple forward within a servlet not supported/allowed?

Look a the docs for the HttpServletRequest object.

The short answer is that request.getRequestURI is probably what you want.

Hello,

I am sorry to ask off topic
but is there any way to know which hyper-link was clicked?
There is a page which can generate dynamically hyper-link
and linked page should know which one was cliked.
I am using jsp and can I use parameter?
Any idea will be appreciated.
Thank you.

RE: Regarding support for tomcat server....................

[CPC Livelink Admin]

I think his point was that neither one was showing any value other than 1,
because the JSP was always recompiled, and then reloaded. Thus the class
variable was being reset to 0 as the class was reladed.

I don't know what's going on with your compile question, but your code is
wrong.  It should look like this:

Take a close look at the ! (bang).

    <%!
      int globalCounter = 0;
    %>

     This page has been visited: <%= ++globalCounter %> times.

     
     <%!
       int localCounter = 0;
     %>
     NOW!  This counter increases its value: <%= ++localCounter %>

If you set a local variable to 0 everytime you run the code then it's always
going to be 0.  So it's never going to increment.  Give localCounter class
scope, just like you gave globalCounter class scope and it will increment.

RE: Regarding support for jsp........

[CPC Livelink Admin]

This 
is working fine for me (I tested your code on my tomcat 3.2.1). It sounds like 
you have a file timestamp problem. Look at the timestamp on your JSP file and 
then the generated Java code. If they are on different filesystems or were 
created by different computers then they may be out of sync.  That is, if 
the JSP is dated somewhere in the future (due to a timezone conflict for 
instance) then when the java file is generated, it has the current time. Next 
time you hit the page, tomcat looks at the timestamps and sees the future time 
for the jsp again so it recompiles.
 
Hope 
this helps,
Paul

It works for me as well. The only caveat is that with text boxes (which I
thought you said you were not using) the browser sends an empty string for
some of the boxes.

Here is some sample JSP code :




<%
String []vals = request.getParameterValues("foo");
if (vals != null)
{
for (int i = 0; i < vals.length; i++)
{
%>
[<%= vals[i] %>]
<%
}
}
%>




Foo
Foo

RE: Tomcat 3.2 throwing a VerifyError at me

[CPC Livelink Admin]

An easy way to find it is to introduce an error in the JSP and look at
Jaspers error message, which includes the full path to the file.

In the work directory will be a .java file that will correspond to
your jsp file.  (The name will be managled, but its fairly straight forward
which file is which).  You won't be able to change how Jasper works, but
knowing which class it wants to create with a no-arg constructor will help
solve the problem.

Sorry for all the questions, maybe I should just leave the system

RE: Using a servlet superclass

[CPC Livelink Admin]

Yes.

Have your WorkerServlets implement a procedure called childInit or
something, which is basically an empty procedure in the SuperServlet.  Then
call this function as the last (or first) call of the SuperServlet init
function. This is much like how GenericServlet makes init() a convenience
call instead of init(ServletConfig config).

Paul

Subject: Using a servlet superclass


I have a number of servlets in my application that need to
perform common initialisation, etc.  So I was thinking of
creating a superclass that has an init method that does all
of the common work, eg.,

public class SuperServlet extends HttpServlet {
  public void init() {
// do common initialisation stuff in here
  } // init
} // SuperServlet

Then all the workers servlets would extend SuperServlet
rather than HttpServlet, eg.,

public class WorkerServlet extends SuperServlet {
  ...
} // WorkerServlet

This seems to be OK, until I implement init in the
WorkerServlet, as the init method in the SuperServlet
does not then get invoked.  While I can call super.init()
in the WorkServlet, I want this to be handled automatically
as I can bet on someone forgetting this step, eg.,

public class WorkerServlet extends SuperServlet {
  public void init() {
// don't want to have to make this call ==> super.init();
  } // init
  ...
} // WorkerServlet

Is there any way to implement this ?

This

I have the Tomcat 4.0 Dev nightly build (? - i'd have to check which one)
running on Windows 2000.
I didn't come across any errors.

The only thing I couldn't do was actually view the examples web app using IE
(i
believe 5.5).
IE does not want to let me connect to 'localhost:8080' offline.  It changes
the
address to 'local:8080'.
Running the examples in Netscape 4.01 worked fine though.

Yep, since it has no JSessionID on the url, it must (by definition) be

Thanks for the response.  From the messages below, it appears that problem

It sounds like if a 'jsessionid' is not passed with the request, then Tomcat
will create a new session.
Is this correct?

One possibility (altough a bad idea) is to stick it into your
session.

Another possibility is to create an object that has a static
variable for the Connection.  Then provide methods to access it.  Remember
that you need to make sure only one thing at a time is using the connection.

There are some pooling connection managers out there already.  One
that I know of off the top of my head is PoolMan.  You can go over to
sourceforge.net and search for it.

RE: Speeding up database accesses

[CPC Livelink Admin]

While there are connection pools (I have not used them but others on the
list can point you to them), I find the easiest solution is a session
variable. Then make a function you can call with the session and db
connection info. The function checks the session for the DB varaible. If
it's not there it creates the connection and adds it to the session. Then
returns the DB. That way the call to get the connection looks nice and clean
(no nasty if statements to cloud up your HTML on the JSP).

Paul

RE: log files in tomcat

[CPC Livelink Admin]

Actually, these are files that are generated by the jk_nt_service helper
application, not entries in tomcat.

If you want to capture the output of tomcat, you need to either a) redirect
the output to a file (on Unix you also need to redirect stderr, on Windows
stdout and stderr are much the same (I think)) or b) programatically change
the stream pointed to by System.out and .err to something else which you
have opened.

Be careful with case. The directory name shoul dbe WEB-INF not Web-inf. Even
though Windows ignores case, it still preserves case, and tomcat enforces
the rules on case sensitivity despite windows.

Also, the WEB-INF directory is protected, so no files will be served from
there.

WEB-INF/lib is the class loader that is used (javas versus tomcats).  Since
I have quite successfully used tomcats in WEB-INF/lib, I am guessing that
maybe there is something a little but different about the jar file. Maybe
you should try to unjar the package, and then rejar it yourself using no
compression and no fancy options (or just leave it unjarred in the
WEB-INF/classes).

Hope this helps,
Paul

Subject: Re: TOMCAT3.2 BUG


You're not alone with this problem.  I was just involved in a couple of
threads on this subject in the JBoss Users mailing list, but everyone who
participated seems to have the same problem.  Here's a link to one thread:
http://www.mail-archive.com/jboss-user@list.working-dogs.com/msg09704.html

I finally worked around the problem by putting everything that would
normally be in WEB-INF/lib and WEB-INF/classes into the main Tomcat
classpath.  This works, but I'd still like to find out what the problem
is...Tomcat? JBoss?, or something else.

Possibly confounding factors in my setup include using JBuilder 4.0 to run
both Tomcat and JBoss, and am using Struts.  Don't know if these could be
affecting the outcome at all because I haven't tried a different setup
without them.

Thanks for any help anyone can provide.

RE: java.sql.SQLException: Io exception: Broken pipe

[CPC Livelink Admin]

He's talking about a database connection pool.  What looks like what is
happening is that you open a connection to the DB once at the beginning,
then save it for later. When you come back in several hours, the DB has
dropped the connection, so when you try to use it, you get that message. If
this is the case, than you need to recreate your connection or better
monitor your connection to see if it has been dropped.

RE: Problems with context-relative path include directive

[CPC Livelink Admin]

The way it nehaves is that "/" is the root of your webapp. So, when doing
things with the servlet container alone, you would reference the file as
"/JSPHeader.jsp". If, however, you are sending something to the browser for
it to get, then do "<%= request.getContextPath() %>/JSPHeader.gif"

Somewhat weird, but it does make navigation from the root of your webapp
easier since the name (context path) of the webapp can be changed.

Paul

I just installed Tomcat 3.2.1 on my Windows 2000 workstation.

I made the following entry in the server.xml file so that I can reach my

The same JSP pages work fine using JRun 3.0. But it appears that Tomcat is
not liking my
context-relative path include
statement because if I change the include to be:

<%@ include file="JSPHeader.jsp" %>

and the JSP page that make this include is at the "root" level for my
context, then Tomcat is
happy...

I was under the impression that my definition of the "/hcs" context should
have taken care of this.

Any thoughts on what I am doing wrong here?

RE: Heartbeat/watchdog signal

In the servlet container, you can start a thread and sleep there and do your
check. You could build a servlet whose whole job is this, using the
LoadOnStartup mechanism to get it to start automatically.

Hi,

This is more concerned with servlet engines in general rather
than Tomcat itself but I had hoped I could get some good ideas
from you.

What I would like to do is have something call a method, or a
servlet in this case, at regular intervals.  The reason for this
is to be able to update this software components' health status.
I guess it is sort of like an SNMP check to see when the last
time some software component has said it is OK.

I am not sure how to implement this inside a servlet container,
or if it can be.  UNIX cron could be setup to do a HTTP / GET
on a servlet at regular intervals, or so could a separate JVM
that slept for a period of time and then called a servlet but
I am wondering if there are any other solutions out there that
people are using to report status on certain components.

Thanks as always,

Aron.

RE: properties files and tomcat

[CPC Livelink Admin]

Actually, there are good reasons to NOT do it that way. You may not have
access to the file system for one, or the property file may be embedded ina
JAR file. Whereas if you use the getResourceAsStream you don't have thise
problems.  However, if you need to access an arbitrary file, using
FileInputStream is the way to go. For general purpose properties file usage,
I reccommend you stay with getResourceAsStream. It makes it easy to switch
the properties files you use by just changing the classpath a little bit.
And it allows you to have defaults buried deep in the class path which are
overridden by the same named resource which occurs earlier in the classpath.

Just my 2 cents.

Paul

You should do this:

Properties myprops = new Properties();
myprops.load(new FileInputStream(new File("my.properties")));

if this doesn't seem to work, make sure that my.properites is in the right
place, and/or qualify the new File() call.

e.g.
new File("d:\tomcat\webapps\myapp\my.properties");

The CLASSPATH is only for loading class files, and will not help you find
the properties file.

I gave up on getting mod_jk working on Solaris.

I've had a similar problem with different builds.  I'd make sure that before
you build it that all of the object files are removed.  My problem was that
there was an object file in a different directory that wasn't removed.
After checking all of the Makefiles and removing it and building again
everything worked.  I ran /usr/bin/file on the object file and it reported
that it was an i386 object file - obviously not useful on a sparc.

Thanks,

Hi there.  I'm trying to get Tomcat 3.2.1 working with Apache 1.3.14 on a
Red Hat 6.2 Linux Box running 2.2.18 Kernel.  Both Apache and Tomcat were
working on this box before I started messing with mod_jk.  I downloaded the
latest stable source (jakarta-tomcat-3.2.1-src) and compiled mod_jk as per
the FAQ.  I had the error message talked about in the FAQ, but the gcc line
generated the mod_jk.so with no problems.  I copied this file into my
libexec dir, and included the mod_jk.conf-auto in my httpd.conf file.  I
stopped apache and tomcat, restarted tomcat, and then tried to start apache
and got this error message:

Starting httpd: Syntax error on line 8 of

Cannot load /usr/libexec/mod_jk.so into server: /usr/libexec/mod_jk.so:
undefined symbol: jk_b_set_buffer_size

Line 8 of the config file is:

I'm guessing that there must have been a problem with the compile of
mod_jk, but not knowing enough about the source I'm not in a good position
to go poking around and trying to fix it.  I did a search on the archive
for jk_b_set_buffer_size but that turned up nothing.  Any ideas?

RE: So can no one help with my Socket Write Error Question ?

[CPC Livelink Admin]

This has been discussed many times on this mailing list.  I did a quick
search through my archive and found these two snippets, neither of which I
know anything about, but thought I would give them to you for your
amusement. These were from messages on December 8, 2000.

-- Snippet 1 
The dev lists suggest the following (that is being
considered for 3.3 dev)
http://w4.metronet.com/~wjm/tomcat/2000/Jul/msg00910.html

Commenting out the following lines -
sout.write( buffer, 0, bufferCount );
sout.flush();

in the method endHeaders() of HttpResponseAdapter.java

The above fix did eliminate errors of the type -
2000-12-08 11:39:27 - Ctx( /estore ): IOException in:
R( /estore + /template.js + null) Connection reset by
peer: socket write error

but the stack trace reported continued.

--

-- Snippet 2 -
I checked the code... it says ignore this message.

Could this be that the JSESSIONID cookie is scoped to the webapp.  IE if
your webapp is called FOO, then only pages below /FOO can get that cookie.

to
go to the ASP stuff.  IIS is happy to create a session/cookie
ASPSESSIONIDGGQQGGED however, if the asp page asks about the cookie
JSESSIONID
(from tomcat), it finds nothing.  Anyone have any thoughts on how to pass

fields to post to the asp page and from there, it can decode the form
variables.
What are some other options?

You need to make a copy of mod_jk-auto because it will alwys be generated

You may be able to write yourself some native code to do the switcheroo for
you. Then use the java calls to the native call. The code to do the user
switch is readily available (though I have not searched for it now, I have
seen it before, and it is also available from apache subject to the ASL)
This, of course, makes you relatively platform specific.

Kitching - Thanks for the response. I was afraid of that.
'ifconfig' is the utility that lets you see information about the
network interfaces, not a firewall. :) Do you run multiple machines with
a firewall in front of them to do the redirection (w/ load balancing for
example) or do you run the firewall on each machine individually?

I asked our operations people about the same thing being done in our
load balancer (F5/BigIP) - but apparently it can't be done there.
Setting up a redirect on each machine could be a pain - not that I'd
have to do it. :)
Thanks again.

XMLFileServlet


com.mycompany.XMLFileServlet





XMLFileServlet

This did the trick in 3.1, but I seem to be out of

something different or additional to get an extension
mapping to work?

RE: webapps are useless toys?!

I think the idea is that Webapps are distinct self-contained applications
and therefore should not depend on _anything_ outside of the webapp. If you
have components which need to share session info, they _should_ be in the
same webapp. You would then build your webapp as you would any application
that has multiple components and possibly multiple developers (very
carefully ;)

Hi,

Does anyone with a need for one session for all areas of the site
(single sign-on for users) find the current JSP specification

It seems like each webapp is a separate servlet context, which means
that there is no way to share session info among different components

I hope that I'm not asking a question that's been asked a bunch of times

Small background:
I'm trying to run tomcat along with apache.  I have apache v1.3.14 and
tomcat v3.2.  I'm using the jk module for the layer, not jserv.

On startup:
I get a BindException which says that the address is already in use.  I
assume that this is referring to port 8007 (my ajpv12 port).  I have
rebooted the machine to make sure that this does not happen.  I have a
shell script which first starts tomcat then apache.

On shutdown:
It appears that the port is never released.  When running the shutdown.sh
script, I get a NullPointerException and it ignores signal 15 (the kill
signal?).

Sorry for the lengthy email, but I wanted to give as much detail as
possible.  I'm not on this alias, so please reply to me directly...

Many thanks,

RE: security-constraint url-pattern not working

This was discussed earlier.  Here is a snippet from the post by Craig
McClanahan :

In your , you are specifying  entries that
are
not legal according to the servlet specification (such as "*/WCFAdmin.jsp"
and
"*/wcfsystem").  The legal syntax only allows "*" wildcards at the *end* of
the
URL, not the beginning.  If JRun supports these values, it is doing so
outside
of the servlet spec, and is therefore not portable.

For more information on the legal syntax for URL patterns, and pretty much
everything else that is mandated about servlets, see the Servlet API
Specification, version 2.2, which you can download from

to be protceted  under Orion and JRun, whereas Tomcat lets me access it
without any constraints:

*/WCFAdmin.jsp

If I change the pattern to:

/jsp/admin/*

all servers behave equal, protecting all pages in the given subdirectory.
Now, I wonder why Tomcat ignored the first specification. I suppose this is
a bug, but on whose side (JRun & Orion, Tomcat or mine)

Take a look at the multipart classes by Jason Hunter that are free for use
if you own the book "Java Servlet Programming" from O'Reilly. The code can
be downloaded from O'Reilly's site www.ora.com

I have only had one problem with it, and I think I have coded around it.
The problem was that sometimes uploads from MSIE 5.01 Win do not send the
boundary correctly (it varies by two characters everytime).

RE: posting to servlets from a url

[CPC Livelink Admin]

Well, then I think your next best bet is in the Tomcat 4.0 release which has
the new Filter and Valve features. My only knowledge of these is from one of
Craig McLanahan's posts, but if you check the spec, it will probably
describe them in detail.  My understanding, is that these would allow you to
do exactly what you want - however, I don't know if you can wait that long
or if you are able to use the 4.0 milestone builds in your environment.

I think your next best bet is to disable the /servlet/ auto-mapping (I
believe this is a tomcat extention) which should prohibit access to the
stuff in WEB-INF/classes and lib (but sill allows access to all JSPs). Then
have all access to your servlets be through inclusion or direct execution.
I am not sure of the rules for direct executition so you may want to refer
to the spec to see if that is allowed.

Paul

RE: scope of a bean

[CPC Livelink Admin]

If you use response.sendRedirect then you are telling the browser (ie
client) to open the supplied URL.  The browser then makes a new request for
that URL.  So, if your bean is scoped to a request, then it will be out of
scope for the redirect.  If it is scoped for the session or application,
then it will still be there.

On the other hand, if you do a forward operation (pageContext.forward) or an
include, then tomcat handles it all internally, and so it is all one
'request', so a bean scoped as request will be seen by all the pages
included or forwarded to.

Does this clear it up?

Paul

RE: Your thoughts on organizing multiple web apps

[CPC Livelink Admin]

I believe that what you have stated is the generally accepted practice,
though some may argue that there is NO good time to put a jar in the
TOMCAT_HOME/lib directory. If you are on a system that permits it, the use
of links (hard or symbolic) is also suggested to reduce storage space
requirements.

Something else to look for is the system classpath, which tomcat will
inherit on startup, unless you modify tomcat.bat/tomcat.sh or use another
mechanism like the jk service on NT. Having like jars in the system
classpath has bitten me a couple of times when I migrate from development
into production. I have therefore wrapped my tomcat startups with a minimal
classpath which I know I will set on all machines.

Finally, and I invite more enlightened comments on this topic, tomcat has a
'feature' which allows the use of a global web.xml file to supplement the
applications web.xml.  Since I believe that this is not a portable feature,
you may want to ensure that you have everything in the applications web.xml
file that you think you will need, and not count on any system defaults.

Paul

Subject: Your thoughts on organizing multiple web apps


We've got a heterogeneous collection of internal applications running under
the same Tomcat installation, and have recently had some problems.

This collection has "evolved" and changed as we learn more about using
Tomcat, and the problem seems to be that some webapps (particularly the
earlier ones)  were installed with the .jar files they needed being put into
/lib and when another app (which required, for example, a
different version of some class) was installed with the .jars IT needed
going into WEB-INF/lib the .jars in /lib "shadowed" the classes
the new app needed.

General consensus here seems (in hindsight) to be that /lib is
***NOT*** the place to put .jar files UNLESS the Tomcat administrator can
ensure that every app that will be installed will be happy with them.
Otherwise, the webapp should keep the .jars it needs in its own WEB-INF/lib
even if that means some duplication of .jar files across the collection of
webapps.

Has anyone else had similar experiences, and what were your solutions?

RE: cgi-bin

[CPC Livelink Admin]

As has been mentioned earlier on this list, Tomcat does not have any CGI
capabilities.  This could, however, be implemented in a servlet.  A general
call went out to see if anyone was interested in writing one, but I did not
see any takers.

To implement what you want to work, you will need to place tomcat behind
another web server like apache or iis.  Then you can use them to do your
cgi, and tomcat to handle your servlets.

RE: is it possible to dynamically create and interpret JSP?

[CPC Livelink Admin]

Sure it's possible - depending on your JVM's security manager.  If you have
access to write to your document root directory, then you can write a file
to that directory and then redirect/forward to it.  It will then be compiled
and executed. You will probably want to create a directory in the webapp for
the session to keep from stomping on other sessions files. You would also
want to listen for the session ending event(s) to clean up the files after
the session is over.

I know you all are going to tell me to follow the directions, but I have!
I've
sent the unsubscribe several times to no avail.  I think it's Lotus Notes

the way it translates email addresses from it's internal naming system to

RE: temporary page

[CPC Livelink Admin]

 
Put 
your processing in a background thread.  Put a META Refresh tag in your 
HTML to refresh a monitoring servlet priodically. If the processing is not done, 
the monitoring servlet returns the same refresh tag, else it forwards/redirects 
to the real data you want to show.
 
Or you 
could load an applet and use it to maintain contact with the servlet (I know it 
can be done, but I don't have the details.)

RE: Multipart stuff - inside JSP?

[CPC Livelink Admin]

I use it all the time in my JSPs.  I don't understand why you are trying to
embed the source in the JSP instead of just using it though - Here is how I
use it :



<%@
page language="java"
import="java.io.*, java.util.*"
errorPage="load-action-docs-error.jsp"
%>
8< snip >8
<%
  String FileDestination = strMSUploadDir + java.io.File.separator +
session.getId();
  File fUploadDir = new File(FileDestination);
  fUploadDir.mkdirs();

  com.oreilly.servlet.MultipartRequest multi = new
com.oreilly.servlet.MultipartRequest(request, FileDestination,
iMSMaxFileSize);

  Enumeration files = multi.getFileNames();
  while (files.hasMoreElements()) {

... etc (like HTML) below ...

Hi,

I was looking at the multipart request handler from oreilly,
(www.servlets.com), is it possible to use the same class INSIDE jsp? I mean
in the declaration tags

<%!

class MultipartRequest...

%>


and then call it from there? This is giving me a hell lot of problems.
First, all the IMPORT tags in the class were giving me a problem, so I
removed all those, but now it gives me a problem with the "Hashtable" from
java.util.*, so I removed all of that, and the reference to all "Vectors"..

Now it doesnt work! ALways gives me the "premature ending" IOException..

Please help! Is there something that I cannot do inside the JSP declaration
tags? How to go around this?

Thanks!!!
Mike

RE: Getting servletinputStream from a specific field of the posted form?

[CPC Livelink Admin]

You need to get a multi-part post data handler.  There is one at
www.servlets.com (the O'Reilly servlets site) which is not wuite free (must
buy the book to use it commercially), but does work well.  If you browse the
archive, (http://marc.theaimsgroup.com/?l=tomcat-user&r=1&w=2 is one
archive), then you can search for other messages on this topic which show up
periodically.

Subject: Getting servletinputStream from a specific field of the posted
form?


Hello

A small question, hopefully this is completely JSP-related (I think it is).
I have a form where a couple of the fields are of type ,
which are used to upload images etc.

I would like to get the files posted through these two fields, and save them
to a pre-determined folder on the server. I came across something called:

 request.getInputStream();

but how would I specify exactly which file I wish to save?

I am a bit clueless here, and would appreciate a few pointers. I know that I
can write to a file by using a FileOutputStream, but before I can "put" a
file like this, I need to "get" the bytes from the posted form. Is there
anyway to get this? Request.getparameter just returns me a string, right?

Thanks a lot in advance,
Shanx

RE: Shutdown problem

[CPC Livelink Admin]

 
It is 
still the environment problem. The 2816 setting is just an estimate, since it 
will be affected by other environment variable you have set, what paths you 
choose to put things in etc.  Increase that number by a lot (be absurd in 
your first test) and try to shutdown.  You should not see the problem 
- assuming you don't just bing down the amount of environment memory until the 
problem reappears and set it (finally) to be above that 
level.

RE: can't get tomcat to compile...servlets.

[CPC Livelink Admin]

Not positive, but this may be that you did not specify tools.jar on your
command line.  I beleive I saw sometime a long time ago on this list that
this was required to compile anything in-process. You probably will need to
update the startup script to get it correctly (since it didn't get it
itself).

If this doesn't work, I have no more clues.

Paul

RE: getParameter is NOT a string?

[CPC Livelink Admin]

It is acting correclt. Both user and "admin" are java objects, and they are
not the same one, even though they have equivalent string values.  Object
equivalence is what == tests.  The test you want is :

if (user.equals("admin"))
{
}

Hi I am getting a form field (POSTed form) as

String user = (String) request.getParameter("user");

When I out.print this, it writes the correct value, but when i COMPARE this
in an IF condition, it doesnt work. Any reason why? For example, lets say
the "user" textfield in my form is "admin".

Now when I grab it using getParameter, the value printed out is admin!! But
when I do this condition:

if (user == "admin")
{
}

then it doesnt go into this condition, but goes into the ELSE instead!!!

Why is this?

Would appreciate any help..thanks!!

RE: [Basic] JSP help!

[CPC Livelink Admin]

1.  In a jsp you can use response.sendRedirect("") to send the browser
an instruction to open another page.  Forward does like you say - totally a
server thing.

2.  I believe it is request.getContextPath

3.  Go to the Java site (www.javasoft.com) and go to their tutorial or search
on google for Java Tutorial and you will find a wealth of tutorial info.

1. How do you "redirect" a page? I have code that

if string == a then
 forward to page 1
else
forward to page 2

Unlike ASP, the forward tag just sort of INCLUDES the file! The file name in
the browser is the same..not that of the file that I am forwarding to! What
is the command to really REDIRECT the page by changing the URL of the
current browser window?

2. How can I get the current path of the script? I mean something like
 REQUEST.SERVERVARIABLES("SCRIPT_NAME")
or  REQUEST.SERVERVARIABLES("PATH_INFO")

3. I need to know some string manipulation functions like substr etc...most
JSP books assume you know Java, where can I find a good beginner's reference
to all these functions?

I would really appreciate if someone can help! Thanks!

RE: Number of Instances

[CPC Livelink Admin]

Here's my humble attempt to explain.  The single thread model says to the
servlet container that your servlet should only be run on one thread only.
Multithreading in the server is then implemented by creating multiple of
your single thread model servlets, one for each thread that is required to
respond to requests.

When are your inits being called?  Is it possible that your servlet is being
garbage collected and then respawned?
