BufferedReader oject between servlet and jsp

object between a servlet and jsp page using the session. on the jsp page I
want to read out line by line the BufferedReader object. The idea works
within the servlet code as shown, but within the jsp page no matter what I
do
out.println(br);
shows something like this:
java.io.BufferedReader@3c550f
and the while loop (in the jsp) never executes. Any ideas? (how can i
troubleshoot?)
I have a servlet with the following code:
===
BufferedReader br = new BufferedReader( new
InputStreamReader(proc.getInputStream()));
HttpSession session = request.getSession(true);
session.setAttribute(BufferedReader, br);
String str;
while ((str = br.readLine()) != null) {
System.out.println(str);
} //works
and a jsp page which is called from the servlet like this
RequestDispatcher rd = request.getRequestDispatcher(en/bdy.jsp);
rd.include(request, response);
bdy.jsp
=
%@ page import=java.io.* %
%
BufferedReader br = (BufferedReader) session.getAttribute(BufferedReader);

out.println(br);

Subject: Where's my fish? How do I go fishing? (Tomcat 4.0)
Hello,
Tomcat 4.0.3 is apparently not reloading a recompiled servlet. According
to the docs, this should be the default behavior.
Interestingly, it WILL load a new servlet.
I have 2 questions, of the where's my fish sort and of the how do I
fish sort.
Where's my fish: why isn't Tomcat reloading my changed servlet? I have
verified that the class file has changed by checking the timestamp, so
I'm pretty sure it's not a build problem.
How do I fish: what is a reasonable way to troubleshoot this problem?
While I would love to have a fish right now, I am perfectly willing to
learn how to fish and catch my own.
Some fishing I've already done:
1) tried restarting tomcat. Picks up the new class!
2) tried restarting the browser. No go.
3) examined the tomcat logs. Nothing interesting.
4) examined the servlet class file in the webapps dir. Yup, it sure
changed.
5) tried adding a second servlet. Tomcat picks it up!
6) tried changing the second servlet. No go.
I *suspect* that in the murky depths of this problem swims an enormous
caching flounder. Is its name Tomcat 4.0.3? Is it IE 5? Either way, I
want to hook it, filet it, and have it for dinner tonight.
Thanks for your help,

The site has alot of people hitting it because it is close to easter and people are ordering from this site. Well, I was wondering what could cause this runaway process in tomcat. I have check all my loops and logic it doesnt seem to be any infinite loops in the code. Has anyone else had this problem with tomcat? If anyone has a suggestion to track this problem down or someone who has a similar problem please respond as soon as possible. Ive spent about 1 week on this and cant seem to find the problem. I really need to get this fixed immediately.

RE: changing a user's password on linux using jsp exec.
The only password you could ever change is the one for the user Tomcat is
running as (nobody i believe).
I've been down the road you're going down. Your options are:
-1- (compiling apache/tomcat to run as user root (unreasonable on anything
other than a intranet environment). big security hole.
-2- you can use the expect programming language.
-3- you can hand the passwd execution to a cron job that runs as root. just
dump the user to change password into a text file. grep the text file every
5 seconds or something from cron. if an entry exists chpasswd on it and
delete the entry from the file. cron is very light weight. see man chpasswd

RE: changing a user's password on linux using jsp exec.
Do a man chpasswd from the linux command line. See the format it expects
(user_name:password). Just write the username and pw into a file using that
format from your tomcat app. (say the file is: /tmp/new_pw). chown new_pw to
nobody.nobody or chmod it 666.
Then in your /etc/crontab file add:
05 * * * * root chpasswd /tmp/new_pw
This will run the chpasswd as root every 5 seconds. Actually rather than
calling chpasswd from cron I would create a shell script that does some
checking to make sure that your web app isn't trying to change the pw for
root or any other important system users. And that also empties the file
new_pw after chpasswd is run. Be careful. Don't look yourself out of your
machine on my account ;-

Hi Dahnke,
The cron idea seems interesting. Do you have something
working? Or even an example for me to follow.
Thanks.

You can turn on logging with MySQL with the -l flag. I'll assume you're running on a unix* system. Where MySQL starts up add a -l flag to it.

Sharing a bean between servlet and jsp. Arrggghhhhh
Now I'm going crazy. This can't be so hard. Please help... I can't figure
this out. I'm trying to share a bean between a jsp page and servlet.
Arggh... Please I help on other lists... and donate time to
charity. I've been to Barnes and Noble and looked at a heap of texts. I've
done no less than 500 Google searches.
There are no errors, I just can't get this jsp:getProperty
name=myFormBean property=userName / goddamned thing to display the
userName bean property if fb.validate() fails. Everything works. I've got
this begugger and can see the userName variable throughout the POST process.
Everything's cool until the rd.forward (request, response), but once the
forward takes place my jsp cannot again pick up the bean properties
eventhough I say jsp:useBean id=myFormBean class=beans.FormBean
scope=session/ I've tried every scope, and am using beans with straight
JSP no problem (same application).
Any ideas? Millions of Thanks
Here's the JSP page.
===
jsp:useBean id=myFormBean class=beans.FormBean scope=session/
form method=POST action=controller
input type=text name=userName
jsp:getProperty name=myFormBean property=userName /
input type=hidden name=event value=FORM_TEST
input type=submit name=submit value=next
/form
Here's the two relavant parts of the servlet.
public void process (ServletContext sc, HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
FormBean fb = new FormBean();
fb.setUserName(request.getParameter(userName));
if (fb.validate()) {
URL = index.jsp;
} else {
// go back
URL = signup1.jsp;
}
}
public void forward (HttpServletRequest request,
HttpServletResponse response) throws IOException,
ServletException {
RequestDispatcher rd = request.getRequestDispatcher(URL);
rd.forward (request, response);
}
Here's the bean
===
package beans;
public class FormBean implements java.io.Serializable {
public String userName;
public FormBean() {}
public boolean validate() {
boolean allOk=false;
return allOk;
}
public String getUserName() {
//return this.userName; // doesn't work either
return userName;
}
public void setUserName(String uname) {
this.userName = uname;
}
}

Using a JavaBean from within a servlet
Hello,
This is killing me. I've got a form that posts to a servlet. I simply want
to get the form variables into a bean's properties.
I can find only one reference to what I'm trying to do here. it is a
formToBean() method from a FormUtils package, that some company sells.
Reading form variables into and out of javabean from a servlet has to be a
common activity. I can find heaps of info about using beans from JSP pages
(specifically about introspection), but I need to manipulate bean properties
from both Servlets and or JSPs. How do I do the introspection thing within a
servlet?
Code included below.
JSP Post to a Servlet. - Servlet instantiates a FormBean -
FormBean.validate() is called. - but the validate() is always false because
the bean property vals are empty. Do I have to explicitly read each
request.getParameter(FORM_VAR) and set that to a bean property?
// from the servlet
//
FormBean fb = new FormBean();
fb.setProperty(*); // * this aint workin - here *
if (fb.validate()) {
URL = WELCOME;
} else {
// go back
URL = INDEX;
}
// from FormBean
//
private String UserName;
private String Password;
public boolean validate() {
Debug.log (this, validate,GETTING THIS FAR AT LEAST);
boolean allOk=true;
if (UserName.equals()) {
errors.put(UserName,Please enter a username);
//UserName=;
allOk=false;
}
if (Password.equals() ) {
errors.put(Password,Please enter a valid
password);
Password=;
allOk=false;
}
return allOk;
}
public void setUserName(String uname) {
UserName = uname;
}
public void setPassword(String pword) {
Password =pword;
}
public String getUserName() {
return UserName;
}
public String getPassword() {
return Password;
}

how might I get at that FormBean instance from either the Welcome or Index

I have properties in the FormBean class pertaining to error_msgs and such
I'd like to get from the jsp. For the instance of the FormBean object that

formBean.setPassword(request.getParameter(password));
