RE: JAXMServlet + SOAP

[Dahnke, Eric]

I recently did this by parsing the SOAP Message (via JAXM) with SAX. My
parser class happily takes an XML file or any kind of input stream, so I
just wrote the SOAP message out to a OS (did a OS -> IS conversion as
follows).


// write the SOAPMessage to an OutputStream, convert that to
// a string and close the OutputStream
ByteArrayOutputStream baos = new ByteArrayOutputStream();
message.writeTo(baos);
String strSOAPMsg = baos.toString();
baos.close();

// now build an InputSource to send to the SAXParser 
// from the strSOAPMsg 
StringReader chrStream = new StringReader(strSOAPMsg);
InputSource is = new InputSource(chrStream);

// this is the code to call the SAXParser (goes with the
// SAXParseHandler class) 
SAXParserFactory spf = SAXParserFactory.newInstance();
SAXParser parser = spf.newSAXParser();
parser.parse(is, new SAXParseHandler());

Subject: JAXMServlet + SOAP


Hi

I've got a Servlet which extends JAXMServlet and i'm trying to
write some code to process received messages.


I am following the Sun example
http://java.sun.com/xml/jaxm-0_9_2-prd-spec.pdf


To get a DOM from a SOAPMessage you need to do this apparently:

 DOMSource domSrc = (DOMSource)
soapEnvelope.getContentAs(DOMSource.FEATURE );

However, the "getContentAs" method does not exist on the SOAPEnvelope.


Have any of you come across this?

Has anybody got a code sample that shows how to get a DOM from one of
the SOAP
objects in the JAXM api?

thanks
Paul

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,

BufferedReader oject between servlet and jsp

[Dahnke, Eric]

wondering if someone might help me out. I'm trying to pass a BufferedReader
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");
String str;
out.println(br);
while ((str = br.readLine()) != null) {
out.println(str);
out.println("HI");
} //doesn't work
%>

Hello all,

I have finally debugged enough to find out that my tags are being executed
twice (on a number of pages) because the page seems to be loaded twice. Does
anyone know why a page would be loaded twice? I thought that a
document.form.submit()
would cause a signal post to the same page.

Any answers or explanations would be appreciated.

RE: TOMCAT STOPS!

If this is true:

If we use lynx on the server running Tomcat, we CAN access the
pages.

then Tomcat is not your problem, and it is more likely a networking /
firewall issue. When it goes down what does telnetting to port 80 show you?
How about traceroute?

could also be a hostname dns thing. when you run lynx do you use localhost?
What is the  exact URL you use in lynx?

I've followed this thread and am still having no luck. Here's the situation.
The TC that comes with jwsdp is TC4.0b7. This release of TC doesn't include
a tomcat.exe file, so I grabbed one from the TC4.0.1 release. I then run
following from the cmd prompt.

"%CATALINA_HOME%\bin\tomcat.exe" -install Tomcat

Response is:

The service was successfully installed.

Upon starting the service I get:

"Could not start the service on Local Computer. The service did not return
an error. This could be a Windows error or an internal service error."

the stderr.log file is created but is empty.

Apologies in advance if this feels spammy.

I have been working with a few folks on a grassroots way for people to
donate money to various non-profits & projects such as Apache, Hurd,
EFF, or even to a given developer.  This donation might be in response
to some helpful feedback given by that developer in response to a
question; it might be because their name and URL were in some software
they used.  Affero takes a bit off the top for our expenses , which we
think is reasonable given the costs involved in credit card auth and the
like. The software used to deliver the service is open source.

Take a look at a the link I created below

People can go to that URL and donate money, 35% of which goes to the
Squid, 35% to XFree86 and 30% to FSF Gen Fund-GCC.

We're very interested in any comments and feedback on the
site/service. You can check it out at http://www.affero.com.
BTW, we have been told that we should lower our $15.00 minimum donation.
What do you think?

Using a JavaBean from within a servlet

[Dahnke, Eric]

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("") ) {

I'd like to get from the jsp. For the instance of the FormBean object that
validate() was run on.

What I do is something like this:

// assuming we are creating a new session for login
HttpSession session = request.getSession(true);

FormBean formBean = new FormBean();

formBean.setUserName(
request.getParameter("userName"));

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

if ( formBean.validate()) {

session.setAttribute("formBean", formBean);
URL = "Welcome";

} else {

URL = "Index";

}

Sharing a bean between servlet and jsp. Arrggghhhhh

[Dahnke, Eric]

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 "" 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  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.
===








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;
}
}

RE: How can I tell who is connecting to the database?

[Dahnke, Eric]

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. Below is how it is on my machine
(linux RPM install)

$bindir/safe_mysqld -l --datadir=$datadir --pid-file=$pid_file &

then your log file will be created in /var/lib/mysql/your_host_name.log

RE: changing a user's password on linux using jsp exec.

[Dahnke, Eric]

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.

[Dahnke, Eric]

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.

Problem starting Tomcat4 (starts then stops)

[Dahnke, Eric]

Hello,

Does anyone know why upon running ./startup.sh my RH7.1 box briefly shows
some java activity, but then quits. Here is the output of ps ax. These
processes live for a few seconds then... nothing.

I've seen something similar where the problem was because of a different jdk
running, but in my case there is nothing. i do a killall -9 java before
running startup.sh and still get the same problem. Nothing ever gets put
into catalina.log. TIA

Subject: runaway process in java while using tomcat


Hello,

I am hoping someone can help me with this problem I am having.
I am using tomcat 4.0.1 to run a web site with jsps. This site uses alot of
database connecting with Informix.
For some reason, usually within 2 hours of starting up tomcat, a process
will start to take up 100% of the CPU.
The time it takes for this to happen varies.  Ive tried to reproduce it on
a test site by myself but cannot seem to reproduce it.
It only happens when alot of users are using the site and some user seems
to be causing this to happen.
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.

Thanks in advanced,

Dave

RE: how to set env varible

[Dahnke, Eric]

This has always been a question of mine too. You've got to get the modified
environment variables (JAVA_HOME, CATALINA, etc) to the user session
starting Tomcat.

Often times I've had to reboot as all users get the env variables read to
them from /etc/profile at startup. Hope that answers your question. 

Is there not a way on linux (*nix) to broadcast new system wide environment
variables w/o logging out (that user) or su'ing to that user and manually
running export JAVA_HOME=/usr/java..
