RE: Where to locate class files

[Ron Day]

Are you using packages for your java code? If not that is your problem.

The default package is NOT the "classes" directory, but "org.apache.jsp", so
if you don't explicitly use a package name, and put your class files in
"classes", Tomcat will not find them.

Use a package name such as com.pk1.pk2 and put a directory structure
com/pk1/pk2/ under classes. Put your class files in pk2.

Subject: Where to locate class files


I am developing an order form to run on Tomcat. The book I have says to
store the class files in \webapps\root\web-inf\classes
directory. The html file is located in the root directory and runs fine but
when calling the jsp the error is:Class org.apache.jsp.Spud not found.  Is
this the correct directory to store class files? Any ideas appreciated.

Here is your problem

Make your class part of a package, then reproduce the package in the
WEB-INF

For instance, if you call your package  com.MyFiles   put the Java file
in WEB-INF/com/MyFiles

Then in you jsp, do an import  com.MyFiles.Spud

No, only servlets are registered in web.xml. You really do need to use
packages believe me...

You have to put your java classes in a package. If you do not, and put 
the class files in WEB-INF/classes then Tomcat cannot find them because 
this is not the default package location for Tomcat.

Bottom line: always use pacjages for your classes !

tomcat 4.1.12 much slower than Tomcat 4.0.3

[Ron Day]

I just installed Tomcat 4.1.12.

But now my tomcat 4.0.3 webapps run about 10 times slower.

Anyone have any ideas as to why this may be.

I did not change anything, and it happens for jsp's and servlets !!!

RE: tomcat 4.1.12 much slower than Tomcat 4.0.3

[Ron Day]

Thanks for the tip.

I understand your first servlet tag, but I do not see why the
servlet-mapping tag is there. Shouldn't this be in the global web.xml file
in /conf.

Any idea why we have to do this "hack"

Ron,

I had the same problem, and fixed it with this same web.xml for all my apps
(this goes in the WEB-INF dir of each app):

*


http://java.sun.com/dtd/web-app_2_3.dtd";>

  
 home
 home
 1
  
 
  invoker
   /servlet/*
 

**

I found that if I preloaded the first servlet (in my case, home) everything
ran OK after that.

RE: tomcat 4.1.12 much slower than Tomcat 4.0.3

[Ron Day]

Yes, I'm aware of that. I was more interested in Scotts servlet tag. Even
more I am hoping someone has a better way to get my 4.1.12 install working
correctly (at same speed as 3.0.4).

not start-up but running webapps..

I just installed Tomcat 4.1.12.

But now my tomcat 4.0.3 webapps run about 10 times slower.

Anyone have any ideas as to why this may be.

I did not change anything, and it happens for jsp's and servlets !!!

I tried your suggestion several times, and rebooted as well, but still no
improvement. I can run a simple one form,one servlet example in both tomcat
4.0.3 and 4.1.12 with no code changes. In 4.0.3 the response is
instantaneous, but in 4.1.12 it takes 10-15 seconds for response, and does
this on all subsequent submissions of form. A strange problem !!!

Ron, the first solution (load on startup) is just for servlets that have a
load of detail to do the first time they start up and has nothing to do
with our situation.  The second part (servlet-mapping) is just creating a
security problem that the release notes explained should not be done.  I
had the problem you had, and as I said, I solved it by rebooting Tomcat and
cleaning out the work directory. I was working at the time with linux
RedHat and had to make sure the work file was completely cleared as
well.  I don't know what happened, but it was with 4.1.12 and it happened
twice.  Both times, restarting Tomcat worked.  Why, I don't know.  Micael

tomcat 4.1.12 much slower than Tomcat 4.0.3

[Ron Day]

Hi,

I have tried re-installing Tomcat 4.1.12 , moving to JDK1.4.1, but:

My original post, still happening: This is post.

**

I just installed Tomcat 4.1.12.

But now my tomcat 4.0.3 webapps run about 10-20 times slower.
These are my class exercises, ranging from small single servlets to medium
projects.

Anyone have any ideas as to why this may be.

I did not change anything, and it happens for jsp's and servlets !!!

It seems that the tomcat examples work fine !

I did not change anything in 4.1.12.

No XML parsing. Same Windows machine, same memory.

If I revert back to 4.0.3 it works fine and faster than 4.1.12.

My test cases are very simple (by design to find reason it is slower)...
most use no 3rd party libaries, a couple use log4j.

Strange huh ??

Hi,

My setup is much faster with tomcat 4.1.12 than 4.0.x

What kind of things are you doing with your servlets/jsps ? Which libraries
are you using ?

Do you do a lot of XML parsing ?

Did you disable tagpooling ?
Do you have less memory assigned to the process than before ?

Beans in packages vs beans not in packages

[Ron Day]

Hi,

When I run a webapp with a bean in a package -- say "com.form", everything
works fine. But when I try to run a bean that is not in a package I always
get class not found error.

1)I am using usebean in both cases, one has class name, one has full package
name.
2)Bean has package name in one but no in the other.
3)Bean is in class directory at top level for no package, and in correct
package directory structure for package.

There are no other changes, except to recompile bean, and restart tomcat.

Any help appreciated.

Subject: Re: Beans in packages vs beans not in packages


Actually, it's quite simple.

You see, your Java source files only have "package" scope for classes that
are not imported. This means, that your source can only refer to classes
within the same package directly. All others must have a fully qualified
package name (e.g. java.util.Collection) or be imported.

The 'import' statement requires a fully qualified class name, and the class
name includes its package.

Classes that have no 'package' statement are in an Unnamed package.
Typically this Unnamed package is the "Current Directory", which is a
logical name, not "usr.will.javacode.projects.test". But, since the classes
are unnamed, you can't get a fully qualified name for them in your source
code.

Packages are a wonderful thing, but their relationship with path names and
directories (which is an implementation detail) causes SO much confusion for
people.

You can 'import' your classes from the same package, even though its
unnamed, and even though you don't need to, it's "legal".

If you have X.java and Y.java in the same directory, where Y imports X, and
with both files lacking a 'package' statement, the 'import' will work. It's
just unnecessary.

This is why the imports will fail for your classes, even though they're on
the CLASSPATH. You can't properly name them.

Q.E.D, that's why your classes need to be in a package.

Best Regards,

Will Hartung

I don't believe that's what I said at all =) What I was was that to the
best of my recollection that's how it is supposed to act. Isn't
encodeURL what you're supposed to be able to depend on when cookies are
disabled? If it doesn't list the parameters/cookies in the url ... then
what is it for? =) Ok - here I go digging through the docs *cringe*. Now
... you tell ME what the correct interpretation is:


  encodeURL

public java.lang.String *encodeURL*(java.lang.String url)

Encodes the specified URL by including the session ID in it, or, if
encoding is not needed, returns the URL unchanged. The
implementation of this method includes the logic to determine
whether the session ID needs to be encoded in the URL. For example,
if the browser supports cookies, or session tracking is turned off,
URL encoding is unnecessary.

For robust session tracking, all URLs emitted by a servlet should be
run through this method. Otherwise, URL rewriting cannot be used
with browsers which do not support cookies.


*Parameters:*
|url| - the url to be encoded.*Returns:*
the encoded URL if encoding is needed; the unchanged URL otherwise.


That's off of Sun's JDK docs for J2EE 1.3. I think it danged well better
have the session in it if cookies are off!

I don't know why I was thinking attributes would be there ... the
sessionid is really the only piece you need to track things you are
persisting.

I don't believe that's what I said at all =) What I was was that to the
best of my recollection that's how it is supposed to act. Isn't
encodeURL what you're supposed to be able to depend on when cookies are
disabled? If it doesn't list the parameters/cookies in the url ... then
what is it for? =) Ok - here I go digging through the docs *cringe*. Now
... you tell ME what the correct interpretation is:


  encodeURL

public java.lang.String *encodeURL*(java.lang.String url)

Encodes the specified URL by including the session ID in it, or, if
encoding is not needed, returns the URL unchanged. The
implementation of this method includes the logic to determine
whether the session ID needs to be encoded in the URL. For example,
if the browser supports cookies, or session tracking is turned off,
URL encoding is unnecessary.

For robust session tracking, all URLs emitted by a servlet should be
run through this method. Otherwise, URL rewriting cannot be used
with browsers which do not support cookies.


*Parameters:*
|url| - the url to be encoded.*Returns:*
the encoded URL if encoding is needed; the unchanged URL otherwise.


That's off of Sun's JDK docs for J2EE 1.3. I think it danged well better
have the session in it if cookies are off!

I don't know why I was thinking attributes would be there ... the
sessionid is really the only piece you need to track things you are
persisting.

Help. Absolutely stuck. Tomcat cannot find my bean classes no matter what
when called from jsp pages. From within servlets no problem.

Here is the jsp
---
<%@ include file="pub_hdr.html" %>



<%= FormBean.getErrorMsg("userName") %>

<%@ include file="pub_ftr.html" %>

Here is the bean

package beans;
import java.util.*;
import java.io.Serializable;
public class FormBean implements Serializable {
  public String userName;
  public FormBean() {}

  public String getUserName() {
return this.userName;
  }
  public void setUserName(String uname) {
this.userName = uname;
  }
}

NO MATTER WHAT, as soon as I access the jsp page. This error comes up.
Generated servlet error: C:\jwsdp-1_0\work\Standard
Engine\localhost\messagesmith\en\users$jsp.java:126: Undefined variable or
class name: FormBean out.print( FormBean.getUserName() );

It certainly seems that TC cannot find the FormBean class which lives here:
C:\jwsdp-1_0\webapps\project\WEB-INF\classes\beans.
I've changed that scope attribute to application or page, but it doesn't
change.
With TC3.x I had to do some configuration in the conf/server.xml file, but
this doesn't seem necessary w/ TC4. All the same I've adding the following
context to the server.xml, but it doesn't help.


Anyone have any ideas? It is killing me. Again, I can instantiate the
FormBean class from within servlets, but not from JSP.

I just noticed you have usebean and not useBean. If this is how you coded
it, your Bean is not getting instanciated. That will give you the error your
are seeing. Remember JSP Tags are case sensitive.

RE: Problem calling JAVA BEAN in JSP

[Ron Day]

Its a little more complex than this. It is very wise to put beans in
packages, as there are some issues with using the default package for these
classes. Assuming you use a package in the java code, make sure you put the
class files under WEB-INF/classes in the appropriate directory structures
for your packages. i.e "classes" directory is the root for your packages.

Hi;

I've got jsps running.except for when they call java classes.
I get a 500 error complaining about not being able to find the classes.

My CLASSPATH echos fine.(its pointing to classes not src )

I checked through the docs looking for changes in how 4.03 handles java
classes versus how 3.02 does.

I couldn't find anything.

Can anyone point me to a FAQ that might handle this issue?

Also where can I find startup options to use with startup.sh ?

Thanks in advance

RE: Tomcat 4.03 Classpath

Tomcat 4.0 and above strictly enforces the Servlet 2.2 WebApp directory
structure (3.0 + did not).

Inside "your webapp" folder you put JSP's,html etc. You also need a folder
called WEB-INF (spelling and case important). Inside here are two folders
classes and lib, and your web.xml if you have one. You put your class files
in the classes folder (in full package structure). And I strongly suggest
you use a package. Tomcat does not do well with the default packge.

15 second delays sound like something wierd with your DNS server (perhaps
you've got access logging enabled?) or database.  There's nothing in
Tomcat that would do this -- and, in fact, most users see a performance
boost, especially with JSP pages that use lots of custom tags.

When you say "no other changes" are you taking into account that the
defaults for Tomcat 4.1.12 may be quite a bit different than 4.0.3?  That
is, have you gone through your 4.1.12 server.xml and verified that every
option/parameter is equivalent to the same parameter as the 4.0.3
server.xml, and have you verified that any new parameters or configuration
options in 4.1.12 aren't doing something that you don't expect?

Well, obviously nobody has had any useful ideas based on this description
of the problem :-).  The next step would be to create a sample webapp
illustrating the difference for you, and letting some other people try it.
That's the only way I can see to track down what's causing this.

RE: tomcat 4.1.12 much slower than Tomcat 4.0.3

[Ron Day]

I did a quick and dirty test.
Wrote to console log at last line of servlet, then noticed the time lag was
after this statement was written. Lag of about 8 secs on IE, none on NS
4.75.

Hi,
I'm tempted to mark this as off-topic, but maybe not yet ;)

>Heard of any IE issues  crazy I know, its html by then.

Do you specify a strict HTML DTD?  If so, IE6 will render a bit more
slowly.

How did you determine it's a browser issue?  Do you have a
browser-independent (cactus, mockobjects, load, JMeter, whatever) test
you can run against 4.0.3 and then 4.1.12 to verify response time and
latency differences?

RE: javabean problems

[Ron Day]

Your javabeans are not in a package.Tomcat 4.xx does not like this as it
puts it in the default package, and then cannot find it at run time.

Just put your beans in a package, recompile and then add your package
directory structure under the "classes" directory.

i.e if you have com.my.package for a bean mybean.class, then
put mybean.class in webapps/WEB-INF/classes/com/my/package directory

what is "com".

Either it is part of package name and needs to be added to package to make
it:

package com.testbean;

, or the com directory needs to be removed.

don't use root, use your own webapp.

Don't know if this helps, but I put a Navigator class in
WEB-INF/classes/navigator/ and by accessing its ClassLoader can always tell
what the paths on the server are.  The sole purpose of this class is to
reveal information not capable of being known prior to startup (e.g. is
this Unix, XP, or Memorex?) and providing this to any part of the whole
deal that needs to know.  The parts can then use the information as they
like.  I usually create another class which gives me the location of the
application itself, which is stored in application scope and everything
from there is up to the individual parts to specify where they are relative
to that.

package navigator;

import java.io.File;
import java.net.URL;

public class Navigator {

 public URL location()
 {

 return
navigator.Navigator.class.getClassLoader().getResource("navigator" +
File.separator + "Navigator.class");

 }

}

You still planning to post mod_jk2 HOWTO soon?  The information for that
appears to be scattered (best source is still the source), and usage
instructions are inconsistent from person to person.

Personally, I like the idea of deprecating the properties file in favor of
doing everything in httpd.conf.  I don't know if that is the approach you're
taking.

Hello Tomcat users,

I have just upgraded from Tomcat 4.0.4 to 4.1.12.  My application is a .jsp
page(s) with about 10 light weight applets sitting in a page.  When using IE
to access this, there is a very long delay to load the page or the browser
just hangs.  When using Mozilla browser, everything works fine.

Also noted when IE shows the file names it is loading currently on the
status bar, it loads many files quickly but is getting stuck on small .gif
files.  I found two questions on the web related to this situation, one
asking the jar file takes a long time to download when Tomcat is upgraded.
The other asks about why the .gif files would take a long time to download.
But neither questions has been answered.

Has anybody seen or heard similar problems.  Any help is appreciated.
Thanks

My company uses IE exclusively, and while we don't use 4.1.x in production
yet, we have been doing a significant amount of testing and have not seen
this problem.

If it works in one browser but not another, it's a browser issue.  Do you
have the latest/greatest (I say that with tongue in cheek) updates to IE?
IE is notorious for breaking critical functionality in between minor
releases.  6.0.01 might work fine, but 6.0.02 might be totally
unusable, etc.

Turn off HTTP 1.1 in your browser and see what happens then.  I've seen a
case when the web server (Netscape Enterprise Server??) had HTTP1.1 issues
and had behavior similar to this - some requests would come through, some
wouldn't.  It's worth a try.

Also, are you using Tomcat's HTTP stack or a separate web server?  Which
one?

RE: You used to make your servlet work, but what about a JSP page with a bean?

[Ron Day]

Is your bean in a package? If not Tomcat will not find it in the default
package.

just add "package com.mypackage" to bean source, and put class file in
classes/com/mypackage

Subject: You used  to make your servlet work, but what
about a JSP page with a bean?


I am a newbie experiencing a very frustrating problem.  I have a web
application that uses a packaged javabean.  When I create a web application
with the correct directory structure under the 'webapps' directory (see
below), having created a context in 'server.xml', going to the localhost
page produces the following error:

 HTTP Status 500: ...JasperException: Cannot find any information on
property 'uName' in a bean of type 'coreBeans.FormBean'...

BUT...if I move this application's components in the appropriate directories
under the 'examples' folder, it works (therefore the JSP page and the bean
are not broken in any way).

BUT...if I leave the webapp where it is and disable the bean, the JSP page
works (although that's not a lot of use ) even if I use JSP statements in
it.  I do have Apache HTTP server on this machine, but I mention it without
knowing how this would be relevant in any way.

AND...I tested another web application that uses a servlet and this would
not work either.  HOWEVER...I fixed that by using a suitable
 tag in 'web.xml'.  Unfortunately, I don't think I can do
this with a bean (or can I?).

Does anyone out there know:
1) why my webapp can't find the bean class?
2) why mapping a servlet solves a similar problem for a JSP page using
it?
3) how I can get my webapp to find the bean class?

I won't at this stage post the webapp JSP page, bean code or xml since I
know they work if placed under the 'examples' directory.

This problem has been driving me nuts for nearly a week and if anybody could
shed some light upon it I think I would be close to ecstatic.

TIA,

Wilson

Thanks Ron, but please note bean is declared to be in:

package coreBeans;

and directory structure is

%TOMCAT_HOME%/webapps/core/WEB-INF/classes/coreBeans/FormBean.class

AFAIK that is the correct form, unless you are saying that it has to be:

package com.coreBeans;

and

%TOMCAT_HOME%/webapps/core/WEB-INF/classes/com/coreBeans/FormBean.class

instead.

Also, note bean works if the application components are moved to appropriate
directories under the 'examples' folder.  I'm pretty sure the bean is not
the problem.  It seems to me Tomcat cannot 'see' the class even though it is
in the right place (I think).

Hello Tomcatistinarians (or is it Tomcatistadors y Tomcatistadoras?),

I have a web app which keeps a bunch of useful information in the

support cookies.  I know, that is annoying, but it's something I can't
do anything about.  So, I am trying to figure out what is the best way
to do this within jsp.  It seems like url rewriting is the only way to
go.  There are links all over the place so I want to do this in a way
which is efficient and readable for me, the page designer.  Do I need to

There's not a single JVM per machine. Even if the JVM running Tomcat inside
it is crashed, it's prefectly ok to start another one testing for the
existence or availability of Tomcat and/or a webapp. That will work. It's
just that this solution is a little awkward. Let me summarize the
alternatives:

1) A cronjob shell script using wget as John suggested.

2) A Java Thread running in a different UNIX process, i.e. JVM which
repeatedly tests the webapp's availability like I suggested in my first
posting. That thread runs in a loop and is NOT started regularly by cron but
once when the system starts (aka. init script).

Aside from that, your primary goal should be to get rid of the crash. Ever
tried downgrading to a 1.3 JDK?

RE: Script for checking remote server

Use java code very similar to that in the recent post by Hannes Schmidt (see
Tues 02/25/2003:5.29AM)

I run something like this out of a thread that I initiate in the init method
of my main servlet. It can call a java class to send email or whatever.

What does everyone use to check the status of a remote server?

I am needing a script (or what have you) that will validate that my Tomcat
server is up and running on timed intervals.  If the server is down, I need
to post to a web page that sends either (or both) an email & a msg to my
cell phone (think I have this part figured out).

Anyone care to share some code?  Or offer some ideas?

It would be very much appreciated!

Monitoring the process table with ps doesn't tell you if your application is
available.  It just tells you if the OS thinks your application (Tomcat) is
running.

To remotely monitor/test a web application, your monitor application must
make a full HTTP/HTTPS request and check the content returned as the
response for an indicator that all is well.  Anything else is false
security.

Thanks , two questions...

1) Does the URL creation have to be inside the while loop ?

rather than

   (con.getContentLength() > 0)

> Would you expand on option 2.

A Java thread is a sequence of execution of Java bytecode on a JVM.
Obviously, there can be multiple threads per JVM. A JVM is a native
operating system process interpreting (sometimes compiling on the fly) the
bytecode of at least one Java thread. Since there can be multiple processes
per machine, there can be multiple JVMs per machine. Ideally, these JVMs are
completely separated, at least their address space (memory) is. Sometimes an
operating system provides native threads. These are threads of execution of
machine instructions on the real machine. There can be multiple native
threads per native process. Thus, it is possible to map native threads to
Java threads: the JVM process contains multiple real threads, each executing
one thread of bytecode. I don't think the Sun's JVM does that, but I'm not
sure.

You just have to make sure that the monitoring thread is not executed inside
the same JVM that runs the application to be monitored.

> Why is this a thread rather than a java app that is started on system
> startup ?

Option 2 IS a Java application. It consists of a single Java thread (the one
running the main() method). But it is started only once and it repeats
internally - note the infinite while() loop. A cronjob is a Unix process
that is repeated externally. I use the term externally, because it is
started all over again periodically by an 'higher power', i.e. CRON.
Cronjobs don't usually contain infinite loops. Whether to use internal or
external repetition depends on the situation: external repetetion is more
time consuming but it releases all resources, e.g. memory after each
iteration. Internal repetition is fast but it blocks resources forever,
basically. So if something needs to be executed once every minute I would
strongly suggest internal repetition. If it needs to run once a day only, I
would suggest external repetition.

import java.net.*;
public class Main {
public void main( String[] args ) {
while(true) {
URL url = new URL( "http://localhost:8080/examples"; );
URLConnection con = url.openConnection();
con.setUseCaches( false );
con.connect();
if( con.getContentLength() > 0 ) {
// restart tomcat
}
// cleanup
Thread.getCurrentThread().sleep( 100 ); // or so, I'm not sure
}
}
}

The published code had errors, but the idea of  getting a connection
(url.openConnection)and testing response code in header with
con.setRequestMethod("HEAD") and con.getResponseCode() should work like your
example of a JSP.

I don't think so...the last example I saw was making system calls to ps and
looking for a particular entry in the process table, and the other one I saw
was just checking to see if a response came back (a 404 or 500 or other
error is a valid response but not the one you want).  That doesn't do
anything.  Perhaps I missed another example that was posted.

RE: crontab problems

[Ron Day]

I have code very similar to this that does work... except
whenever I get an unknowHostException, it seems to be cached somewhere until
I bounce Tomcat. My code actually pulses another website (in a thread every
3 minutes)that is on the network, rather than check Tomcat. In place of your
streams, I actually set the request method to "HEAD", and interrogate the
Response Code. This is easy to do in HTTPURLConnection.

I instantiate the URL outside the loop (and hence only once), and I am
wondering if this is the source of my problem. I plan to test it ASAP.

RE: crontab problems

[Ron Day]

Sorry, I wasn't very clear.

I have a Struts application. My heartbeat thread that checks the other
server, is spawned from the init method of the controller servlet, so
bouncing tomcat restarts the heartbeat thread.

My issue is, once the heartbeat program gets an UnknownHostException , for
some reason. The heartbeat program keeps thinking there is a
UnknownHostException until it is restarted (by bouncing Tomcat), just like
it was cached somewhere. I was thinking that getting the URL object every
time though the loop may solve this.

I'm not sure what else would cause it.

The DNS issue clears up , but the heartbeat still thinks there is an
exception.

Regarding your problem: I don't understand why bouncing Tomcat would resolve
a DNS problem. The UnknownHostException is a indication that something is
wrong with DNS or the resolver library.

Because the underlying classes sometimes cache a negative
response, so you have to restart tomcat to enable a new 
lookup. (That's not specific to tomcat)

Good Morning (bad weather here in Dallas)

Thanks for the detailed look at this..

The exception is thrown by the getResponseCode() method of

Good morning!

When I deliberately use a non-existing hostname in order to force the lookup
to fail, the exception is thrown in a method indirectly called by
HttpURLConnection.connect(). This means that the lookup is not done in the
URL class, which in turn means that moving the URL instantiation into the
loop won't help anything.

Where do you get your excepetion? My guts is telling me that the lookup
result is cached by the operating system rather than a Java class. On the
other hand, caching a negative result should never be done by anything. So
the behaviour you illustrated is really strange. What platform does your
webapp run on?

I checked the properties file and I am using defaults, so cache on
unsuccessful should be 10 secs. Mine is sure acting like it is "Forever"
(until new jvm is started)

It's the java implementation that does the caching, as java implements
the lookup on it's own and doesn't use the operating system functions
for that. (That doesn't mean that the operating system or the resolver
lib is not caching, but that is independent
of the java problem.)

The lookup behaviour can be configured, have a look at:

The web application developer I'm supporting has instructed me to ask:

Would this be true if the jsp or session didn't have application scope?
If it isn't true for session scope then it's a design not JDK issue..

RE: request parameter question ...

[Ron Day]

Attributes and Parameters are different. Parameters only arrive as part
of a querystring or in a form post. Attributes are more general, and can be
set by the programmer. That said, they are set and read using different
methods. several responses to your post suggested using xxx?param=yy or
using a forward. Both these will set a parameter that you can read with
getParameter.

I guess if i use setAttribute ... i have to use getAttribute ... thats
the reason i get the blank string .. coz i was using getParameter

my problem is that the jsp uses getParameter ... it would have been
good if i could have used the same method regardless as how the
parameter was set.

RE: request parameter question ...

[Ron Day]

Don't need to do this. You can use a requestDispatcher in servlet to perform
a forward (BTW: that's ultimately what a jsp relies on anyway !!)

then I would suggest to make your servlet into a jsp page, and that way you
can use the jsp:forward to pass parameters

There is no default id/password for either the manager or admin apps.
