Re: Fail secure state
Yes, which has security modules and settings which may fail to be loaded or might be unloaded from tomcat if the computer fails to start up or shut down correctly. In that case, how does tomcat handle that failure?

Re: Fail secure state
Fail-secure is a condition achieved by the application server in order to ensure that in the event of an operational failure, the system does not enter into an unsecure state where intended security properties no longer hold On Thu, Jun 23, 2016 at 3:33 PM, Mark Thomas <ma...@apache.org> wrote: > On 23/06/2016 20:21, Jason Ricles wrote: >> Does tomcat have a secure state if system initialization fails, >> shutdown fails, or aborts fail? > > Define "secure state", "system initialization", "fails", "shutdown" and > "aborts" and we might be able to help you. > > Mark > > > - > To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org > For additional commands, e-mail: users-h...@tomcat.apache.org > - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Getting confusing websocket error message on Tomcat 7
I am trying to send a file over a websocket in binary and keep getting this error "code [1009], reason [No async message support and buffer too small. Buffer size: [800,000], Message size: [131,170]]" I am confused since it is saying the buffer size is too small but the size is 800,000 and the message size is 131,170.

Tomcat feature request
Is there any formal forum to make a feature request for tomcat? I noticed I was having a silent failure with a binary websocket with tomcat since I didn't flip the bytebuffer from write to read and the send kept failing down at the low level of the code without any error being thrown. With that in mind, I was thinking it would be useful to explicitly throw that an error happened since I spent 1.5 days to debug that when I changed the code I just forgot to flip the bytebuffer and had no excpetion being thrown, it would thus be very helpful for debugging purposes.
Having Java websocket server in tomcat handle ISO8859_1
I have an application that sends binary websocket messages between a class and the web application using a websocket server written in java. The data being sent from the java class is encoded in a binary buffer with the bytes in ISO8859_1. However, when I receive the bytes on the websocket server and the web application end they are junk (such as -121, -116, etc.) and not encoded the correct way that they need to be. I was reading that this might be caused by something being set in my websocket server and web application to use UTF-8 for the default and not ISO8859_1. Is there any way I can change my websocket server and my web application which uses JavaScript to use ISO8859_1 instead of UTF-8? - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

Re: Send a message from java application to a specific websocket session via Tomcat websocket server
So that a user can see their own error, but these should only happen if there was an error on the backend. But I do not want to disconnect the users, however if 5 people are connected I dont want all to see user 1 had an error since user 2,3,4, and 5 would think what is this.

If you are stuck on 7.0.53 then you might be out of luck. It depends
what the problem is. The comments on the test case or trace stand but

the
following piece of the code
//further up in the code input buffer is set
inputBuffer = new byte[Constants.DEFAULT_BUFFER_SIZE];
//calculation of reserve
int b = inputBuffer[readPos++];
fin = (b 0x80) 0;
rsv = (b 0x70) 4;
if (rsv != 0) {
// Note extensions may use rsv bits but currently no
extensions are
// supported
throw new WsIOException(new CloseReason(
CloseCodes.PROTOCOL_ERROR,
sm.getString(wsFrame.wrongRsv,
Integer.valueOf(rsv;
}
However I have noticed when the line int b =
inputBuffer[readPos++];
it sometimes changes the value of the reserve bit from 0 to a number
between 1-7. Why would this be changing the reserve bit? Is this
possibly an error with what I am doing or an error due to the class
from tomcat that is running?
Most likely a Tomcat bug.
First of all, upgrade to the latest 7.0.x release. There have been
fixes
since 7.0.53.
Next, try and create the simplest possible test case to recreate the
issue. Failing that, try capturing a Wireshark trace for the
connection
that is failing.

Error with finding of reserve bits in websocket frame tomcat 7.0.53?
I have tomcat 7.0.53 and have been having a problem with the following
error when sending a binary message CloseReason: code [1002], reason
[The client frame set the reserved bits to [x] which was not supported
by this endpoint] where x is between 1-7 when printed out. So I
remote debugged and stepped through the WsFrameBase.class source code.
This source code is what sets the reserve bit so I stepped through the
following piece of the code
//further up in the code input buffer is set
inputBuffer = new byte[Constants.DEFAULT_BUFFER_SIZE];
//calculation of reserve
int b = inputBuffer[readPos++];
fin = (b 0x80) 0;
rsv = (b 0x70) 4;
if (rsv != 0) {
// Note extensions may use rsv bits but currently no extensions are
// supported
throw new WsIOException(new CloseReason(
CloseCodes.PROTOCOL_ERROR,
sm.getString(wsFrame.wrongRsv, Integer.valueOf(rsv;
}
However I have noticed when the line int b = inputBuffer[readPos++];

Re: Error with finding of reserve bits in websocket frame tomcat 7.0.53?
Due to some regulations out of my control right now we can only use
tomcat 7.0.53. I also did a wireshark bug trace and going over the
line the reserved bits are 0 but when computed in tomcat that is when
the reserved are set to invalid bits. Is there any possible solution
or am I just out of luck with tomcat?

Well the trace is fine so I will upgrade and try and see what happens.
If it is not fixed I assume I should file a bug report.

If you are stuck on 7.0.53 then you might be out of luck. It depends
what the problem is. The comments on the test case or trace stand but
the response may be It has been fixed. You need to upgrade.

Yes it was a bug so we will try to get a waiver to use 7.0.57 for our
environment instead of 7.0.53

No luck try to find a blocking call or having the websocket server reader go off into another thread. so basically no way around this problem it seems?

Use one of the blocking methods (i.e. one without a Future or SendHandler). A variation way is to call setBatchingAllowed(true), call the writes (probably with the blocking methods) and then setBatchingAllowed(false). If the messages are smaller than the buffer, they'll set in the buffer and then you'll get a blocking write to empty the buffer when you call setBatchingAllowed(false). I should add that the Javadoc isn't as clear about the expected behaviour for non-blocking writes as it is for blocking writes but the model as I understand it is that the previous write has to complete before the next write can start.

Re: CloseReason 1002
Ok more information it was not the back to back writes that are done on the client side, I have a bytebuffer message that is 23,000 bytes and thats where the error with code 1002 happens sometimes not 100% of the time about 2 out of 5 times. However an 800 byte message in a bytebuffer has no problem 100% of the time.

Use one of the blocking methods (i.e. one without a Future or SendHandler). A variation way is to call setBatchingAllowed(true), call the writes (probably with the blocking methods) and then setBatchingAllowed(false). If the messages are smaller than the buffer, they'll set in the buffer and then you'll get a blocking write to empty the buffer when you call setBatchingAllowed(false). I should add that the Javadoc isn't as clear about the expected behaviour for non-blocking writes as it is for blocking writes but the model as I understand it is that the previous write has to complete before the next write can start.

Back to back writes to websocket server weird behavior
I have a binary queue that I am writing to a websocket server written
in java from a client end point with the following code,
while((bbuf = messageQueue.take()).get(0) != 0)
{
bbuf.position(bbuf.limit());
bbuf.flip();
for(Session session : sessionList)
{
session.getBasicRemote().sendBinary(bbuf);
}
}
However sometimes the 2nd message is dropped or the first message is
sent with no data. Why might this be happening, instead of the
messages getting sent correctly with no data lost 100% of the time?

Websocket @OnMessage is never firing for binary messages only text
I am writing a websocket communication with the client and server
endpoints both in java code (using tomcat 7.0.53 as the web server)
When I send a text message using the
session.getbasicremote.sendText(String) method the @Onmessage function
is fired and everything. However I want to send binary data between
the websockets so thus have to use
session.getbasicremote.sendBinary(ByteBuffer). The code should then be
read within the following method,
@OnMessage
public void recieved(ByteBuffer byteBuffer)
{
System.out.println(byteBuffer);
}
However the method is never fired when the message is sent (I debugged
through both remote debugging and print statements to verify that the
binary data is being sent also yes regular text does get sent through
this method when binary is switched to text). Does anyone have a clue
why this method is never being called when the data is sent from the
other end of the websocket? Here is also the code for the part where
the binary data is sent over the websocket. Also the @onError methods
are in the classes and never called either.
public void SendMessage() throws IOException
{
for(int i = 0;iMESSAGE_SIZE;i++)
message+='\0';
for(int i = 0;iID_SIZE;i++)
id+='\0';
ByteBuffer bbuf = ByteBuffer.allocate(1000);
bbuf.put(id.getBytes());
bbuf.position(33);
bbuf.putInt(33,length);
bbuf.position(37);
bbuf.put(message.getBytes());
for(Session session : sessionList)
session.getBasicRemote().sendBinary(bbuf);
System.out.println(sent);

Yup that flip did it and it works. Yes haha that was one of the many
reasons I didn't major in something with more writing. Luckily its
just a test method thats why I didn't double check the spelling.

1. I think that you are missing bbuf.flip() here.

session.getBasicRemote().sendBinary(bbuf);

Re: How to access Sessions outside of class
foo is not a webapp, it is a separate program running on the computer as a daemon.

Re: How to access Sessions outside of class
Yes Chris RMI is a pain in the ass and I have been trying to make a websocket client endpoint now. It however keeps closing and I am not to sure as of why right after the connection is open. http://stackoverflow.com/questions/26636452/tomcat-clientendpoint-websocket-keeps-closing has the code, asked the questions on there and have not gotten any answers. If you could you may look at the code and reply in this email chain why it keeps closing right after it opens. It is straight forward (as of what i know understand) my ignorance was due to being new to tomcat and websockets so sorry for any of that.

Grab the Tomcat Websocket client library and write your code to use it for communication. Or use any other Java-based Websocket client library.

I have tried the various ways to get it to work in init.d and it's

That's good.
I think it has something to do with the fact that to run the
script manually I am logged in as root, whereas for it to run
automatically it has to run in the background.
/etc/init.d are not usually run in the background. Most /etc/init.d
scripts are processed as root on boot, so that shouldn't matter.
I will include the script info in this email and see if you had an
idea as to where the issue is.
So in /etc/init.d, there is a script called Tomcat, here is the
start portion of the script. Once again, when I run this
manually while logged in as root it launches.
#!/bin/sh # Apache Tomcat Startup Script # chkconfig 234 20 80
JAVA_HOME=/opt/jdk1.6.0_45 CATALINA_HOME=/opt/tomcat
TOMCAT_USER=tomcat
start() { echo -n Starting Tomcat: su $TOMCAT_USER
$CATALINA_HOME/bin/startup.sh
I'm not sure that's going to work. man su. On my system, the command
comes first (with a -c switch), the username last. You might want to
consider using sudo instead of su.
sleep 2
Sleep? Why?
}
I tried creating a new script and putting that one in rc.local.
Here is the rc.local command:
#!/bin/sh # # This script will be executed *after* all the other
init scripts. # You can put your own initialization stuff in here
if you don't # want to do the full Sys V style init stuff.
su tomcat /opt/tomcat/bin/startup.sh
This is a total rookie issue I am surebut just in case you
might be able to help with an easy enough fix, I would greatly
appreciate it. I don't even know where to look for error logs to
troubleshoot this.
Don't use rc.local. Use /etc/init.d/[whatever]
Remember that /etc/init.d scripts aren't directly executed at boot:
you have to ln -s each script into /etc/rcX.d where X is the
runlevel number into which the machine is booting.
Hope that helps,

Re: How to access Sessions outside of class
Communicate means something happens that the daemon is monitoring, so thus the daemon sends a message to the websocket server running on the webapp, so that message can get relayed to the webpage from the server and the daemon will also need to get messages from the webapp. It will then be two way and just regular messages.

Yes we are trying to portable, well the socket is the last resort. We are trying to avoid it until now but will go that way if we have to if there is no other way.

Re: How to access Sessions outside of class
Thanks Tim, That seems like the way to go. IT avoids us having to write our own protocols and everything and instead just code the logic for what action to take when a certain message is received.

Since it sounds like you can't introduce any additional software packages, you might want to consider using RMI (see the java.rmi package). At least then, you're coding to an API instead of having to invent message formats and protocols.

Make a ws:// connection to your web application in Tomcat and then two-way communication is possible. Take whatever values from either side and push them over the wire. Use JSON or something dirt-simple as your data encapsulation language: it's standard, well-understood, and has parsers and serializers readily available for many different languages. It's also pretty much backward- and forward-compatible since everything is pretty much a named value map, so you can add/subtract fields at will without having to rewrite the communication protocol or do a lot of extra work in either the client or the server. - -chris On Tue, Oct 28, 2014 at 8:59 AM, Martin Grigorov martin.grigo...@gmail.com wrote: On Tue, Oct 28, 2014 at 2:51 PM, Jose María Zaragoza demablo...@gmail.com wrote: 2014-10-28 13:44 GMT+01:00 Jason Ricles jgr...@alum.lehigh.edu: Martin, I can not use hazelcast due to regulations I have to abide by, is where any other built in way besides sockets that will allow me to share data between the two processes?

tomcat websocket communication with external java program

I want this websocket server to be able to communicate with an external java program without an sockets, so something like this webpagewebsocket serverexternal java program However I am having trouble getting that to work, since to use the websocket server I need to make an instance of it and thus it thinks there are no session. So currently I have done it the following way webpage-websocket server--socket---external java program This is kinda messy however, so is there some way to get my external java program and my webpage to communicate through websockets without a socket go between?
