Tomcat websocket server onclose failed( Tomcat 8.5)
Dear All,
A problem happen when tomcat websocket server was used.
A sensor data chart with sampling freqency 50Hz is drawn. Tomcat
websocket server( Version 8.5) is used to push the data with 20ms
interval. The server code is as following:
@ServerEndpoint("/websocketendpoint")public class WsServer {private
Session session;private boolean keepingrunning;private static
CopyOnWriteArraySet webSocketSet
= new CopyOnWriteArraySet();
@OnClosepublic void onClose() {
System.out.println("Close Connection ...");
keepingrunning = true;
webSocketSet.remove(this);}
@OnOpenpublic void onOpen(Session session) {
System.out.println("Open Connection ...");
keepingrunning = true;
this.session = session;
webSocketSet.add(this);
}
@OnMessagepublic void onMessage(String message, Session session) {
System.out.println("Message from the client: " + message);
try {
Random r = new Random();
// keep sending data
while (keepingrunning) {
int daf = r.nextInt();
this.session.getBasicRemote().sendText(Integer.toString(daf));
Thread.sleep(20);
}
} catch (Exception ex) {
ex.printStackTrace();
}
System.out.println("end");
}
@OnErrorpublic void onError(Throwable e) {
keepingrunning = true;
e.printStackTrace();}}
The client is as following:
var ws=new WebSocket("ws://localhost:8080/WebSocketTest/websocketendpoint");
function start_webserver(){
ws.send("ac_1");}
ws.onopen = function(evt) {
console.log("Connection open ..."); };
ws.onmessage = function(evt) {
console.log( "Received Message: " + evt.data);
if(chart.series[0].data.length > 400) {
chart.series[0].addPoint(parseFloat(evt.data), false, true, false);
} else{
chart.series[0].addPoint(parseFloat(evt.data), false, false, false);
}};
ws.onclose = function(evt) {
console.log("Connection closed.");
ws.close();};
ws.onerror = function (evt) {
console.log("error: ", evt);
};
function end_webserver(){
console.log("end the connection");
ws.close();
console.log("over");}
// the button
Start
stop
Questions:
When start button clicked, the client can recieve the data to display the
chart continously. But the stop button clicked , the onclose function both
on client and server side did not call. It seem that onclose function is
blocked by the onmessage function because the server keep sending data.
Another websocket sever is tested and no problem happed. So is is the bug
of tomcat socketserver ? Thanks.

Hi, I have a servlet/jsp application running on tomcat 7.0.47. There are no static html files. Now I am try to use apache 2.4.7 (Ubuntu) as the front and forward eveything to tomcat.

Re: mod-jk + ssl: requests are not forward to tomcat correctly

Then change the above links to : href="js/jquery.mobile-1.4.5.min.css" Yes. It works. Thanks. It is okay for now. but, if I do not want host these files, what should I do?

mod-jk + ssl: requests are not forward to tomcat correctly
Hi All, I have a servlet/jsp application running on tomcat 7.0.47. There are no static html files. Now I am try to use apache 2.4.7 (Ubuntu) as the front and forwad eveything to tomcat. I installed mod_jk using Ubuntu's software center.. Things are working: I type "localhost" on my brower bar, it shows my application. Then, I also trying to use ssl and generated self-signed certificate. It works, because the browser warns me about unknown certificate. If I type " https://www.mytest.com/index.jsp; on the browser's bar, it shows the page. But not correctly: the page contains: These extra files are not be called. What is wrong on my side?

We have done a lot of searches on the internet and found that many others have
similar issue but we couldn't find a post which explains the root cause and how
to prevent it to happen. Example:
http://www.devconnectprogram.com/forums/posts/list/1641.page
http://apache-xml-project.6118.n7.nabble.com/Could-not-load-DTDDVFactoryImpl-xerces-jar-td1020.html
The most strange part is that it does not happen all the time, but sometimes
(often though).
We did verify the jar file (/opt/java/jre/lib/rt.jar) which contains
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl. It is
always there, and the class can be correctly loaded when this does not happen.
C) More info
Here are the relevant code:
import javax.xml.parsers.DocumentBuilderFactory;
private static DocumentBuilderFactory factory;
factory = DocumentBuilderFactory.newInstance();
try {
DocumentBuilder docBuilder = factory.newDocumentBuilder();
} catch (Exception e) {}
We stumbled into this page
http://www.databasesandlife.com/java-always-explicitly-specify-which-xml-parser-to-use/
The conclusion of the page is that:
Never do the following:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
Because the new instance you get may not be what you want due to the system
properties might have been changed by other apps deployed in the same container.
Yes this is exactly what our code ActiveAlarmList.java was doing!
So we thought that this might be the problem as we do DocumentBuilderFactory
dbf = DocumentBuilderFactory.newInstance(); in our code.
However further investigation reveals that it's not that simple.
We printed out the actual classes our code wants to load (under the condition
when all is working fine - the exception not occruing), they are:
com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl
can tomcat use aio instead of nio in linux?

Re: ConnectionPoolMBean should not expose plain-text DB password
I am not familiar with JIoEndpoint discussed in https://issues.apache.org/bugzilla/show_bug.cgi?id=53139. The issue I'm facing is something different. Apparently, some effort was made to hide the DB password, but the DB password is still exposed via another getter (getDbProperties()). This seems to be a bug to me. DB passwords are highly sensitive information. JMX admins shouldn't see those either. It's not a reasonable assumption that it's okay for JMX admins to see exposed DB passwords (which should never be exposed in plaintext or encrypted form). Those who work in a company would probably concur with this point. Does that make sense to anyone?

1) GET requests cannot have content, and thus having a Content-Type

2) Content-Type header is defined in section 14.17 of RFC2616 as
Content-Type = Content-Type : media-type
and
media-type = type / subtype *( ; parameter )
The media-type is not optional and it cannot be empty.
Thanks for letting me know and your further explanation!

Thank André and Mark for your quick response, detailed answer and references! I'll try to report this issue to Cyberduck. One more question: when I uses current version of Cyberduck to connect Amazon S3, it can accept this kind of invalid request, is it a kind of fault tolerance design of Amazon S3?

Current configuration is: web1 connected to app1 only, web2 connected to app2 only. If app1 is down, all users connected to web1 are out. Is it possible to configure web1 connecting to both app1 and app2 so failover will be available? What extra hardware and/or software do I need? Thanks, Henry

Thank you Chris! I did not use mod_jk before. I will start from the beginning.

Is it possible to configure web1 connecting to both app1 and app2 so failover will be available? Yes. Given your existing configuration, it seems that using mod_jk to connect your Apache httpd instances to Tomcat is the right way to go: mod_jk supports clustering and load balancing in (roughly) the following way: 1. Create a worker for each back-end Tomcat instance you have 2. Collect all the workers above into a balancer worker that will really multiplex between the workers defined in step 1 3. Session-less users are routed to whichever back-end server makes sense based upon your chosen load balancing algorithm 4. Users /with/ sessions are always router to the server that owns their session 5. When a server fails, mod_jk detect this and forwards requests to one of the other members of the cluster 6. When the failed node comes back up, it re-joins the cluster and everything goes back to normal Note that you can either implement sticky sessions (as I have described above), or you can use session replication across your cluster. I'm not a big fan of session replication because of all the messages that need to be sent around. For my production purposes, requiring a user to login again when failover occurs is acceptable. For me, the complexity of session replication is not necessary. Your requirements may differ. For more information on mod_jk balancing and clustering, see this page: http://tomcat.apache.org/connectors-doc/generic_howto/loadbalancers.html This page presupposes an understanding of how mod_jk is configured. If you haven't used mod_jk before, start here: http://tomcat.apache.org/connectors-doc/ and read the links for All about workers, For the impatient, and the reference guide for Apache. If you have more questions, post back to the list. What extra hardware and/or software do I need? You'll want a hardware load-balancer to balance between web1 and web2. As for software, just adding mod_jk to the mix should do it. - -chris -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.9 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkpxxEAACgkQ9CaO5/Lv0PCPFACfbRe3JJwEJhcgGW89bYP8wRrE 7EsAn0N3dM9qCB5thWTq0aFIiJEhbr/I =pM8p -END PGP SIGNATURE- - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Juha, Yes, there is memory leak from application. We contact the application vendor and they do not have patches to fix it for the version which we are using.

Actually, 'suspect' is way too mild a term ... I would be completely astounded if you could... Possible workarounds are: 1. Try running 2 JVMs ( when you have PAE enabled) - of course this may not work in your application (you'd have to have two Tomcat instances.) 2.

Cannot access database with remote shared web hosting
Dear Team, I'm new with Tomcat Hibernate. We have a weird problem: When I test our website locally with Tomcat MySQL, everything is OK. But after I copy our webapp under Tomcat to remote web hosting, I can only access the JSP pages, not able to access data from database. The error on page is below, Data Access Failure JDBC exception on Hibernate data access; nested exception is org.hibernate.exception .SQLGrammarException: could not insert: [com.cmn.model.User] I did Google search and someone said the hibernate mapping maybe not good. In my local Tomcat, I can see bunch of * hbm.xml under work/Catalina/localhost/cmnweb /loader/com/cmn/model/ But I'm not sure the remote Tomcat since it's a shared hosting. My questions: 1) Any idea about above Hibernate Data Access Failure? 2) How does Tomcat decide to load *hbm.xml from my lib cmnweb-dao.jar, but not all .jar in WEB-INF/lib/ ?

Re: Perl Permissions on Tomcat
Yes, I have added debug code to the Perl program, and where it stalls seems to be the following line: $myDatabase = new Win32::ODBC($data_source); It just keeps hanging at that line. If I go to Windows Task Manager, I see perl.exe running, but at a fixed memory space (no changes). Also, forcing perl.exe off the Task Manager unstalls the CGI program and it just prints all the debug comments up to the code I wrote above. Someone suggested that I switch to another JDK but our workplace uses only Sun JDK for production servers...any insights to resolving this other than writing a whole new module in Java? -Original Message- Date: Sun Oct 14 18:29:57 EDT 2007 From: Mark Thomas [EMAIL PROTECTED] Subject: Re: Perl Permissions on Tomcat To: Tomcat Users List users@tomcat.apache.org Li Ye Chen wrote: Script A (the problem script) continues to run after 2 minutes (with partial output some of the time).

Thank Chris for help. I have questions embedded below.

I wonder if the real problem is cannot connect to database, and not SQL syntax error, as suggested by the exception class. [Mike] It's a shared web hosting, thus I cannot see the whole stack trace. If it's a cannot connect to database problem, which file or settings do you suggest to look at? Can you verify that you can reach the hibernate database from your app server? There may be a firewall or other barrier between the two machines. [Mike] The Tomcat and MySQL run on same machine. Can you suggest an easy sample code to verify the connection between both?

Re: Perl Permissions on Tomcat
I assume it's a permission problem since: 1) I'm trying to run script A (the script with the problem), and 2) script B ran with no problems at all, but 3) script A also ran with no problems if executed from the command line directly instead of in the browser via Tomcat server... both scripts A and B are in the WEB-INF/cgi folder of a webapp in the Tomcat server. There are no error messages. Apparently, it may also be a speed issue, since there was once when I ran script A and after a while, I stopped the transmission -- there was actually a partial output from the script. -Original Message- Date: Tue Oct 09 16:54:50 EDT 2007 From: Christopher Schultz [EMAIL PROTECTED] Subject: Re: Perl Permissions on Tomcat To: Tomcat Users List users@tomcat.apache.org -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Li, Li Ye Chen wrote: Hi, I'm trying to run a Perl script on Tomcat 5.5.8 -- I've managed to successfully run read-only Perl script, but the script I'm trying to run connects to the database and needs to write to the local hard drive.

Perl Permissions on Tomcat
Hi,
I'm trying to run a Perl script on Tomcat 5.5.8 -- I've managed to
successfully run read-only Perl script, but the script I'm trying to run
connects to the database and needs to write to the local hard drive. Whenever I
try to execute the script, it creates a Perl.exe thread on my Windows server
and just never return the HTML code (so the browser keeps loading) -- it seems
there is a permission problem. I've tried executing the script on plain old DOS
and it works just fine (returns the right HTML code with database information).
I've also searched the mailing archives, and tried changing the catalina.policy
file by adding the following line:
// Give all permission to servlets-cgi.jar
grant codeBase file:${catalina.home}/server/lib/servlets-cgi.jar {
permission java.security.AllPermission;
};
but it doesn't work. Any idea how I can give Perl.exe read/write permission as
executed through Tomcat 5.5.8? Thanks in advance!

Re: Using Tomcat 5.5.23 with jdk 1.6.0_1
Defaultly tomcat 5.5 only support up to JDK5. If you wanna run your application which was written by JDK 6, you can use Tomcat 6 + JDK 6.

Re: [OT] RE: Embed license to tomcat
Hi all, Thanks for you guys last time regarding my boss 'funky' idea for software protection. Since I am still his employee and a responsible developer, I am still planning to finish up this task. Now i am at in the forest which got a bit lost. Let me clarify again what I am going to achieve: 1. Compile all JSPs into .class (done) 2. Create key generator in order to generate Key and later put it into both Tomcat and our system 3. Create encryption key generator for the class files encryption 4. Create encrypt util class to do the encryption 5. Create my own classloader which can be used by tomcat to decrypt our class files 1 and 2 seems ok for now .. 3 and 4 is also tested fine (I am using DES for now). I had wrote a simple classloader which extends JVM's default classloader. It's decryption works fine with simple class files. When I was trying to make a similar implementation for tomcat. I found it's not that easy. There are few paths in my head which made me dizzy: Path 1. Make an independent classloader which extends URLClassLoader Path 2. Modify WebappClassLoader Path 3. As the classloading doc mentioned, configure customized loader which is located in shared folder I had tried Path 3 and it never gets me success. Any ideas about implementing custom classloader for this special purpose? Li

Embed license to tomcat
Hi guys, Our company is going to deploy a system externally. In order to prevent illegal deployment by our customer to other tomcat in case. My boss asked me to embed our license ID into the tomcat by building our own tomcat. I had done several work such as creating a manager for our customized tomcat to checkout MAC ID of the machine and license ID of the deployed system. I am not so sure this is a good solution for securing deployment and our system. Any ideas? -- Small win by playing smart Big win by playing honest

Any modern server can easily handle thousands of concurrent users. But that doesn't answer concurrent requests. Which should be 100/sec. But there are 2 major factors - use of HttpSession is light - Using HttpSession for users can kill scalability due to memory constraints. (YMMV) - Amount of work each request takes - images/css will be served very quickly as compared to JSP's or servlets which utilize database connectivity or file access. -Tim Li Ma wrote: Thanks for the suggestions.

Re: Peak load of Tomcat-powered server(s)?
Thank you all for all the answers and suggestions. Here're what I have got so far from you guys: 1. There's no way to tell a number, because there're too may factors that will definitely influence my mileage. Hehehe, I have expected this number. So I especially appreciate those who did put some numbers in their reply. 2. I need to do load test to know how far I can go. Yes, I think I will. Anyway, thank you, everybody, for your nice answers so far, especially in a holiday period. Now comes other questions I want to ask: 1. I was told Tomcat can only run max 3 nodes in cluster smoothly. What's your milage? 2. This is not related to Tomcat, but if a site has N registered users, what is the average percentage of concurrent user should I expect? I ask this because my client wants 1million registered users. But he wants me to support 20% concurrent users, which I believe is way impossible! But I need to have some number to give him the right sense. This is also important for me to setup the target. Thanks again! Li On 12/26/06, Christopher Schultz [EMAIL PROTECTED] wrote: Li Ma wrote: Actually you can imagine the server serves a site like mySpace where people can access their own home, blog, images, forum, etc. It's always different. If your disk array is different from someone else's, the answer will be different. If you are using 100baseT instead of gigabit, the answer will be different. If you have different speed memory, or better or slower motherboards, the answer will be different. What you really have to do is load test the environment. There is simply no substitute for load testing on equipment and deployment layout exactly matching your production environment. If you don't do this, you will fail. Another question, how many threads do you think Tomcat can have on one machine? That depends on the number and type of CPUs (x86 is not very specific), the amount of memory, and how much work each thread is doing. For instance, you can create tons of threads that never get used, and it will only hurt your memory usage (but will be totally worthless). If you enable 500 threads, but only use 100 of them, is it worth having 500? Probably not. And will increasing number of threads help processing more requests? I think 100-150 per server per second is not a good number. No. Your servers will be bounded by a performance number that can only be determined empirically, given target (peak) load and observations from production. But if it is true, does that mean Tomcat is not suitable for large website? And what does commercial products like WebLogic can normally do? Wow. Haven't we just gone over the is TC okay for big website use? question? Short answer: yes, TC will do just fine. Long answer: any dumbass can make anything go slow. A better question (for yourself) would be how much load do I need to handle? Do you have any target performance stats? How about a sense of the cost of the average request (usually measured in weighted database operations; SELECT is faster than INSERT or UPDATE, for instance)? Do you do any heavy operations such as XSLT? How about any other network operations such as RMI or anything like that? If you can get away with a one-box wonder, DO IT -- at least to start. It's the fastest solution per rack unit that can really achieve. Once you have performance targets, you can start to load test your setup. If you can meet your targets, you are done. Otherwise, start buying more hardware and scaling your app both horizontally (more app servers) and vertically (more physical tiers). Another course of action is to try to trim your app a bit if you are /almost/ hitting your targets. If it's a matter of a couple of % off of your target, then you might be able to make it up by streamlining an algorithm, optimizing your SQL queries, or adding an index or something to your tables. Often, Java and/or your app isn't the problem... it's your (poorly designed/configured/maintained) database. Good luck with ... all that. -chris -- Li Ma [EMAIL PROTECTED] http://www.idealtechs.com

Hi Rashmi,
if there is problem with retrieving correct remote IP address, log4j will
not solve problem ...
it seems like this:
remote user ---(send request) --- your proxy (or maybe you use some
connector or forwardor) tomcat
if 127.0.0.1, seems your connector or forwardoer is located in the same host
as your tomcat sharing same IP address or hostname
if not 127.0.0.1, seems the request comes from proxy

Thanks for the reply.
As indicated in your illustration, in your case the remote IP address
(IP of the client browser) is correctly displaying.
But in my case, for some reason even when my website is accessed
remotely it always shows local IP Address (the website's IP address) and not
the remote IP address.
In other words
%a %A %h is translating *always* to
127.0.0.1
68.120.115.43
127.0.0.1
Where 68.120.115.43 is the IP address of the website host and not the
client (remote host).
The website is hosted on a Tomcat 5.5 which is configured as a virtual
host. I wonder if the virtual host setting might be the cause for not
logging the actual remote IP address.
If I can't get Access Log Valve to log the remote IP address then I
might have to try it with Log4J with Commons Logging to log the remote IP
address I guess.

Re: Is it possible to log IP Address of requestor with custom AccessLogValve pattern?
Hi Rashmi,
You can creater your own log handler and pack it as jar and put it under
tomcat lib dir, modify the loggin.properties file to have your handler work.
Also, you can create your own request processor or intercepter to retrieve
source ip from header and pass to logger.

Hi Li and Pid,
Thanks again for your replies.
You are right, I also tried printing request.getRemoteAddr() in a JSP, and
it always lists 127.0.0.1
As you have suggested my site could be behind a proxy, but I don't know
this for sure. I've asked the host provider if this is the case and waiting
for a reply.
I also use Javascript based logging but that only logs requests coming
from a browser and correctly logs the IP address of the requestor however,
it does not log
search engine bots I guess because bots disable Javascript or can't work
with Javascript.

Hi Rashmi,
if there is problem with retrieving correct remote IP address, log4j will

it seems like this:
remote user ---(send request) --- your proxy (or maybe you use some
connector or forwardor) tomcat
if 127.0.0.1, seems your connector or forwardoer is located in the same
host
as your tomcat sharing same IP address or hostname

Re: Is it possible to log IP Address of requestor with custom AccessLogValve pattern?
Hi,
I am using my own log handler which is application server independent. the
pattern you use for dealing with proxy is ok, in some case, we try to find
an approach to be adaptive for both cases that with or without proxy. It's
good to hear that you solve your problem.

I have no choice but to use
the x-forwarded-for header. As long as the site is behind a proxy I'll
have to settle with x-forwarded-for . If my host provider removes the proxy
then only I can use %a and %h.
But in your case your *website* is not behind a proxy, that's why
%{x-forwarded-for}i doesn't work for you , I think. So in your case simply
using %a and/or %h is sufficient.
I think %{x-forwarded-for}i could also be used to capture the IP Address
of a *client* that's behind a proxy, but I haven't tested this.
