Re: Loading a DeSerialized Class to WebabbClassLoader Question
Hi again Christopher,
thanks for your note and interest, some more details
inline...

ObjectInputStream should be using the context class loader of the

Can you show us your code (the part that actually loads the bytes
into the ClassLoader to define the class)?
The byte[] arrives at the service as a Base64 string. Base64 to byte[]
is trivial and has been ruled out as a problem. The class type is loaded
using a custom ClassLoader (code as follows)
public class FileClassLoader extends java.lang.ClassLoader {
public FileClassLoader(ClassLoader contextClassLoader) {
super(contextClassLoader);
}
public synchronized Class? arrayToClass(String name, byte[] ct,
boolean resolve) {
Class? c = defineClass(name, ct, 0, ct.length);
try {
this.loadClass(c.getName(), resolve);
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return c;
}
}
This is called by...
ClassLoader contextClassLoader =
Thread.currentThread().getContextClassLoader();
Class? spClass = cl.arrayToClass(null, byArray, True);
Also, where does the de-serialization occur? I suspect in the
webapp, but you haven't described everything in detail (and the
details count).
The problem is (was) deserializing an instance of such an object. Code
uses is as follows...
public Object Base64StringToObject(String str) {
Object outObj = null;
if (str != null) {
try {
ByteArrayInputStream bais = null;
bais = new ByteArrayInputStream(Base64.decode(str));
ObjectInputStream ois = new ObjectInputStream(bais);
outObj = ois.readObject();
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (ClassNotFoundException e) {
e.printStackTrace();
return null;
}
}
return outObj;
}
called by...
Object spB64Inst = su.Base64StringToObject(base64codeStrInstance);
In my service, I've loaded a full class definition and created an
instance of it. At this point it (afaik) must be in the cache of
the WebappClassLoader. However, when an ObjectInputStream is
called to... ois.readObject() on a byte[] of an instance of that
same class, it fail for ClassNotFoundException.
Hmm. Can you post the full stack trace of that CNFE?
Although the class (spClass) is now loaded in my custom class loader,
this fails, the CFNE is pasted at the very bottom of this note (for ease
of reading).
What works...
Using the code form this page...
http://www.jarvana.com/jarvana/view/org/apache/tomcat/tomcat-catalina/7.0.4/tomcat-catalina-7.0.4-sources.jar!/org/apache/catalina/util/CustomObjectInputStream.java?format=ok
And described here...
http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/util/CustomObjectInputStream.html
I implemented this in my application (i.e. not imported from a jar) and
use it like this (unchanged except for the package declaration)...
public Object Base64StringToObjectCustomOis(String str, ClassLoader cl) {
Object outObj = null;
if (str != null) {
try {
ByteArrayInputStream bais = null;
bais = new ByteArrayInputStream(Base64.decode(str));
CustomObjectInputStream cois = new
CustomObjectInputStream(bais, cl);
/ next line is the main difference...
outObj = cois.readObject();
} catch (IOException e) {
e.printStackTrace();
return null;
} catch (ClassNotFoundException e) {
e.printStackTrace();
return null;
}
}
return outObj;
}
And called like this... (cl same object as before)
Object spB64Inst =
su.Base64StringToObjectCustomOis(base64codeStrInstance,cl);
I've read (can't recall where) that the standard ObjectInputStream uses
a class loader of the JVM which may not have visiblilty on the
WebappClassLoader due to the delegation model used by Tomcat. All the
CustomObjectInputStream appears to do is to override one of the methods
of OIS and pass a class loader, but in this case passes 'my'
WebappClassLoader.
When I used this code, the problem went away.
FYI, (for reading the stacktrace), The class spClass is the type
definition for HelloWorldSP.java. The class in the application which is
running when this error happens is called FetchProfAbilities.java.
The object su in the above code refers to an instance of
SerializationUtilities (where the de/serialization takes place).
Please shout with any more questions. I appear to have overcome the
problem, but for my thesis, I would like to
Re: Fw: Can not understand how maxThreads of Connectors works
Hermes Flying wrote: Hi, So is there an explanation for this? All I am interested is make sure that after a limit, clients attempted to connect are stopped based on my configuration on maxThreads and accept count. But I can not figure out how this works. (This all being explained in vernacular language to which experts may object). Threads in Tomcat serve to process requests. Each Thread can process one request. 0 Threads = 0 requests being processed. n Threads = n requests can be processed simultaneously (kind of). Threads belong to either a Connector (by default), or an Executor (if you configure several Connectors to use an Executor, then they use the common pool of Threads of the Executor, instead of their own individual pool of Threads). Having a common pool of Threads between several Connectors is normally more efficient and allows for a smoother operation. Otherwise you could have the case that requests arriving through one Connector (e.g. HTTP) are being starved because this particular Connector has no more Threads available, while on the other hand another Connector (e.g. AJP) still has plenty of capacity. The acceptCount is another matter entirely, working at a deeper level. Before a Thread is assigned to process a request, - the client requests a TCP connection to the server - the server must accept this connection. If it doesn't within a certain time, the client will get an error (connect timeout). - when the server accepts the connection, it goes into a queue. The length of that queue corresponds to the acceptCount of the corresponding Connector. (If the accept queue is already full, the connection request will be rejected). As long as the server does no further action, an accepted connection stays in the queue and the client request does not proceed. If that lasts a long time, the client may timeout (usually saying that the server is not responsive). - whenever the server feels like it (for example, when it sees that it has at least one Thread free to handle a request), it will pop the first connection from the accept queue, and pass it to a Thread to be processed. Now a Thread is assigned to process this request, so one less Thread is available in the pool of Threads. - if another client connection happens now, it goes into the accept queue. - whenever the original Thread is done processing the request, the Thread goes back into the pool of available Threads, and could be assigned to another client request currently sitting in the accept queue. That's roughly how it works. If it does not do so in your case, then it must mean that you are setting your parameters in the wrong place, and Tomcat is either not seeing them at all, or ignoring them because they are not where they should be. The default Tomcat settings are chosen by people who know what they are doing, to obtain a reasonable Tomcat behaviour over a reasonable range of conditions. If you change these settings, you can get a behaviour that is no longer reasonable or balanced. For example, if you set the accepCount to 1 and maxThreads to 1, then you can have the following : - 1 request accepted and allocated a Thread, thus in process - 1 additional request being queued in the accept queue, waiting for a Thread to become available And any additional client request arriving at that time will be rejected at the TCP level. That will hardly result in an error that is understandable by the clients. Intuitively, it does not seem to make a lot of sense to set up a whole machinery like a host, a JVM and a Tomcat, just to process one single request at a time. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

No error noticed It is not only me saying it. The on-line documentation at https://tomcat.apache.org/tomcat-7.0-doc/config/http.html says this : quote maxThreads The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool. unquote Now, considering this, there are a number of possibilities : - the documentation is totally wrong - there is a bug in Tomcat - your Tomcat server is not using this server.xml - or, it being rather unlikely that processing 0 requests is what a normal user would want, the Tomcat developers have coded this so that an obviously nonsensical value of 0 would result in the default (of 200) being applied. Pick any one of the above. 2)You say: you are setting your parameters in the wrong place. This is not the case here.I already send an example server.xml.

This is open-source software, that you get to use for free. This is not to say that it is not good software, nor that the developers do not try to make it as efficient and reliable as possible, nor that the people writing the documentation (also for free) do not make every effort to write it well and accurately. On the other hand, it is kind of expected that people using Tomcat and configuring it, would use a bit of judgment and give the developers a bit of slack. I am not a developer of Tomcat, but what I tried to provide in my explanation is a guideline as to how these parameters are supposed to work. That was to help you maybe find the reason for what appears to you as not working, but which apparently other people cannot reproduce. I just tried with Tomcat 6.0.24 under Windows, and when I set maxThreads=0 in the HTTP Connector, Tomcat starts up without error in the log. But if I try to access it with a browser, the browser loops saying connecting.. and never goes past that point. If I set maxThreads=1, then Tomcat is answering with the homepage. Same thing with Tomcat 7.0.21. So I would say : check that the server.xml below is really the one that Tomcat is using. (Additionally, I would say that it seems that when Tomcat is configured to not have any Threads to process requests, well it just does not process any.

Re: The APR based Apache Tomcat Native library was not found
We have a COBOL back end that handles the core functions of our product. The only way we have for the servlet based front end to get at that data is via a type 1 odbc driver. It is a real pain because it is not thread safe so we have to funnel all the traffic through a single thread. Anyway, I got the APR working and managed to fire up Tomcat with the APR connector but my original problem (in another email) remains. That being that calls to a Comet servlet I created return a 400 response saying that the URL does not support get requests. I tried NIO first and thought that APR would perhaps solve my problem. So now I am giving up and trying to have a go with glassfish instead. Thanks for your help!!

Re: Fw: Can not understand how maxThreads of Connectors works
Hi, I am sure that this server.xml is the one used, since there is no other present. Also as mentioned my plan is to cut network access after a threshold. I used such small values e.g. 0,1,2 to see what happens. Also note that I am not using SUN JVM but IBM. Not sure if this makes a difference From: André Warnier a...@ice-sa.com To: Tomcat Users List users@tomcat.apache.org Sent: Thursday, January 24, 2013 7:14 PM Subject: Re: Fw: Can not understand how maxThreads of Connectors works Hermes Flying wrote: Hi, I don't see how this answers my issue. 1) You say 0 threads means 0 requests being processed. This does not happen. Requests are being processed. No error noticed It is not only me saying it. The on-line documentation at https://tomcat.apache.org/tomcat-7.0-doc/config/http.html says this : quote maxThreads The maximum number of request processing threads to be created by this Connector, which therefore determines the maximum number of simultaneous requests that can be handled. If not specified, this attribute is set to 200. If an executor is associated with this connector, this attribute is ignored as the connector will execute tasks using the executor rather than an internal thread pool. unquote Now, considering this, there are a number of possibilities : - the documentation is totally wrong - there is a bug in Tomcat - your Tomcat server is not using this server.xml - or, it being rather unlikely that processing 0 requests is what a normal user would want, the Tomcat developers have coded this so that an obviously nonsensical value of 0 would result in the default (of 200) being applied. Pick any one of the above. 2)You say: you are setting your parameters in the wrong place. This is not the case here.I already send an example server.xml. Will copy/paste it again bellow Yes, but we cannot check from here if this is really the server.xml that your Tomcat is reading. Are you absolutely sure it is ? How ? 3)It does not seem to make a lot of sense to set up a whole machinery like a host, a JVM and a Tomcat, just to process one single request at a time. I am not planning to do that, but I must see how the system behaves in various configuration. Tomcat does not seem to behave as expected in the trivial case. The trivial case is 0 Threads ? What happens when you set it to 1 ? 4) The default Tomcat settings are chosen by people who know what they are doing, to obtain a reasonable Tomcat behaviour over a reasonable range of conditions What does this actually mean? That we are not supposed to configure Tomcat according to our needs? Of course you can. But if you are using nonsensical values, do you expect a sensible behaviour ? Come on, man. This is open-source software, that you get to use for free. This is not to say that it is not good software, nor that the developers do not try to make it as efficient and reliable as possible, nor that the people writing the documentation (also for free) do not make every effort to write it well and accurately. On the other hand, it is kind of expected that people using Tomcat and configuring it, would use a bit of judgment and give the developers a bit of slack. I am not a developer of Tomcat, but what I tried to provide in my explanation is a guideline as to how these parameters are supposed to work. That was to help you maybe find the reason for what appears to you as not working, but which apparently other people cannot reproduce. I just tried with Tomcat 6.0.24 under Windows, and when I set maxThreads=0 in the HTTP Connector, Tomcat starts up without error in the log. But if I try to access it with a browser, the browser loops saying connecting.. and never goes past that point. If I set maxThreads=1, then Tomcat is answering with the homepage. Same thing with Tomcat 7.0.21. So I would say : check that the server.xml below is really the one that Tomcat is using. (Additionally, I would say that it seems that when Tomcat is configured to not have any Threads to process requests, well it just does not process any. Which seems to me like sensible behaviour under adverse circumstances.) ?xml version='1.0' encoding='utf-8'? Server port=8005 shutdown=SHUTDOWN !--APR library loader.

actually the path names and domain names should be able to be different
Anyway I would say a context.xml file in conf/catalina/path1 (the
hostname)/path1.xml (the context name) should do the trick?
Place the webapp outside the appbase of the hosts and then point the docbase to
the webapp (or just drop the .war with two
different names in the appbases of the two hosts) :)
i want to have one instance of webapp,
which has two paths,
and each of the paths serves the root of different domains
once again:
* one webapp
* has 2 different paths: /path1 and /path2
* served on 2 domains
* when user goes to http://path1.com/ - {webapp}/path1 is served as root path
* when user goes to http://path2.com/ - {webapp}/path2 is served as root path
is it possible?

How to prevent CVE-2012-5568 in Tomcat 7.0.32
Hi, We are using Tomcat 7.0.32 in our application. During a security scan CVE-2012-5568 was reported. Is there a configuration which can help us prevent this vulnerability? I went through the http://tomcat.apache.org/security-7.html but could not find any detail on the same. Thanks Regards, Aditi

There is lots if information in the archives on this. This bugzilla issue is probably the best place to start: https://issues.apache.org/bugzilla/show_bug.cgi?id=54263 We could think about adding some info on this under the Not a vulnerability in Tomcat section on the security pages.
