What port number? How did you start tomcat? Do you see the default application? e.g. http://localhost:8080 Typical web application would have the following folder structure: myapp/ myapp/WEB-INF/classes/com/shivamcompany/myproject/web/MyServlet.class myapp/index.jsp myapp/images/... ... You would either make a myapp.war or just copy the folder into TOMCAT_INSTALL_FOLDER_ON_YOUR_SYSTEM/webapps. Start your tomcat if it is not started. Your application should be visible from http://localhost:8080/myweb How did you compile your servlet? How is your servlet mapped? Are you using web.xml to map or annotations in the servlet code? Your servlet should be visible from http://localhost:8080/myapp/servlet_mapping and would execute doGet(...) method you defined in your servlet (if you just requested the address in the browser). Hope that helps. Good luck!
[SECURITY] CVE-2014-0050 Apache Commons FileUpload and Apache Tomcat DoS
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 CVE-2014-0050 Apache Commons FileUpload and Apache Tomcat DoS Severity: Important Vendor: The Apache Software Foundation Versions Affected: - - Commons FileUpload 1.0 to 1.3 - - Apache Tomcat 8.0.0-RC1 to 8.0.1 - - Apache Tomcat 7.0.0 to 7.0.50 - - Apache Tomcat 6 and earlier are not affected Apache Tomcat 7 and Apache Tomcat 8 use a packaged renamed copy of Apache Commons FileUpload to implement the requirement of the Servlet 3.0 and later specifications to support the processing of mime-multipart requests. Tomcat 7 and 8 are therefore affected by this issue. While Tomcat 6 uses Commons FileUpload as part of the Manager application, access to that functionality is limited to authenticated administrators. Description: It is possible to craft a malformed Content-Type header for a multipart request that causes Apache Commons FileUpload to enter an infinite loop. A malicious user could, therefore, craft a malformed request that triggered a denial of service. This issue was reported responsibly to the Apache Software Foundation via JPCERT but an error in addressing an e-mail led to the unintended early disclosure of this issue[1]. Mitigation: Users of affected versions should apply one of the following mitigations - - Upgrade to Apache Commons FileUpload 1.3.1 or later once released - - Upgrade to Apache Tomcat 8.0.2 or later once released - - Upgrade to Apache Tomcat 7.0.51 or later once released - - Apply the appropriate patch - Commons FileUpload: http://svn.apache.org/r1565143 - Tomcat 8: http://svn.apache.org/r1565163 - Tomcat 7: http://svn.apache.org/r1565169 - - Limit the size of the Content-Type header to less than 4091 bytes Credit: This issue was reported to the Apache Software Foundation via JPCERT.

Hello:
I'm using Tomcat 6.0.24
I want to set a realm per only one application, so I define in its
META-INF/context.xml
?xml version=1.0 encoding=UTF-8?
Context
Resource auth=Container
description=User database that can be updated and saved
factory=org.apache.catalina.users.MemoryUserDatabaseFactory
name=MyUserDatabase
pathname=conf/my-users.xml
type=org.apache.catalina.UserDatabase /
Realm className=org.apache.catalina.realm.UserDatabaseRealm
resourceName=MyUserDatabase/
/Context
my-users.xml is stored in $CATALINA_BASE/conf/
But it doesn't work; a javax.naming.NameNotFoundException exception is
thrown when Tomcat restarts
If I put Resource under GlobalNamingResources in server.xml , works
fine, But I would prefer to held all configuration in context.xml
is it possible ? or do I need to use GlobalNamingResources ?
With the current code: no.
It is hardcoded to do JNDI lookup in the global context.
It might be possible to port localDataSource option from
DataSourceRealm class.
(MMV. It depends on what ClassLoader is active when
MyUserDatabase.startInternal() is invoked).
is the pathname right ?
In general I'd prefer to write ${catalina.base}/conf/my-users.xml,
but that is just my preference.
Best regards,
Konstantin Kolinko

question regarding tomcat source code and dependencies
This question was spawned by two things: I'm reading a book on Dependency Injection The latest security announcement - reading the source for FileUploadBase.java Some reading material suggests that one use a simple factory pattern to move object creation dependencies to a different class. I see where the object dependencies that FileUploadBase.java has, like FileItemIteratorImpl, just simply place those dependent classes in the same java source file. I don't see a problem with that approach, should I? Leo - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I'd been following this thread out of curiosity and was just beginning to think that it was obviously a service configuration error. I don't have the entire thread handy, and haven't looked at MarkMail, but I don't remember anyone asking the OP exactly *how* he installed the service. One would assume he used the bat file that is designed to do this, since he mentions running tomcat from the console using startup.bat (a clear giveaway that he's not using the fine Windows installer package that someone spent a lot of time crafting). Personally, I only use the installer, and never run into startup problems unless I've set some optional parameter to an invalid value, e.g. setting a heap size than 1.5GB on a 32-bit machine, etc. As you said, if you're not seeing any log files generated, then the java isn't even getting started, so it could be several factors, not the least of which is an invalid path to the JVM or the Tomcat jar files, etc. Jeff - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org

I'd been following this thread out of curiosity and was just beginning to think that it was obviously a service configuration error. Agreed, and I was following this thread for the same reason. I don't have the entire thread handy, and haven't looked at MarkMail, but I don't remember anyone asking the OP exactly *how* he installed the service. I had the same thought. One would assume he used the bat file that is designed to do this, since he mentions running tomcat from the console using startup.bat (a clear giveaway that he's not using the fine Windows installer package that someone spent a lot of time crafting). Honestly, I forgot all the specific details of how/when I installed tomcat/tomee as a Windows service, but I found it quite intuitive...using the .bat file approach via Windows Command Prompt. The .bat file informed me of the proper 'usage', and I easily installed tomcat/tomee as a Windows Service, via command line (or .bat file), accordingly. And I do use the tomcat7w.exe to modify java options, etc... I never have to open Windows 'Services' to start/stop tomcat/tomee.

Of course, on a 32-bit Windows you can only run a 32-bit JVM, but I suppose that's not your case.

retain context.xml across war updates
Is there a way to ensure an applications context.xml isn't deleted across reloads of the war file?We have server-specific settings in each context.xml and are looking for a way to deploy the same WAR file across each Tomcat instance. My first attempt at this was to put the context.xml into ~ catalina /conf/Catalina/localhost/ROOT.xml. However, Tomcat deletes the file when the app is unloaded. Is there a setting to tell Tomcat *not* to delete the context.xml in ~catalina/conf/Catalina/[host]/[app]? If not, what is the 'best practice' for providing configuration settings to each Tomcat while also enabling a simple continuous integration and deployment of WAR files for an application across multiple Tc instances. Creating custom war files (one for each server) seems brittle and risky if the wrong war is accidentally deployed on the wrong server. Specifically, context.xml contains custom settings for memcached-session-manager which specifies the primary and fallback memcache host. These would be different for each server when using sticky sessions.

Let's start from the beginning. If you don't get logfiles in the Tomcat/logs directory, then chances are that Windows does not even begin to run Tomcat, and that there is an error right at the start, when it tries to run it. So first read this : http://wiki.apache.org/tomcat/FAQ/Windows#Q11 That will explain /what/ you are actually running, when you (try to) run Tomcat as a Service in Windows, and why it is different from running Tomcat in a command window. Go ahead, read it, we'll wait right here. ... some time later : Now you know - that tomcat7.exe is a Windows executable program - it is the program which the Windows Service Manager tries to start, when you start the Tomcat7 Service - but tomcat7.exe is not really Tomcat; it is a wrapper program that runs the Java JVM which in turn runs Tomcat. And to start the Java JVM, and pass to this java JVM the appropriate parameters, tomcat7.exe reads these parameters from the Windows Registry somewhere. And to be nice, the Tomcat developers have even provided a specialised GUI editor, that allows you to view, set or modify these Tomcat Registry parameters that are used by tomcat7.exe. And that is the program tomcat7w.exe. So go ahead now, double-click on tomcat7w.exe, and look at the information it shows in the various tabs. That is probably where something is wrong. Or else what is wrong, is that the version of tomcat7.exe that you have installed, does not match the version of Windows that you are running. For example, tomcat7.exe is a 32-bit program, but your Windows PC runs a 64-bit version of Windows. Or vice-versa. Or that in the Service definition of the Tomcat7 Service, the path to tomcat7.exe is incorrect. You see that path in the first tab of the GUI. André - Good points. I'd been following this thread out of curiosity and was just beginning to think that it was obviously a service configuration error. I don't have the entire thread handy, and haven't looked at MarkMail, but I don't remember anyone asking the OP exactly *how* he installed the service. One would assume he used the bat file that is designed to do this, since he mentions running tomcat from the console using startup.bat (a clear giveaway that he's not using the fine Windows installer package that someone spent a lot of time crafting). Personally, I only use the installer, and never run into startup problems unless I've set some optional parameter to an invalid value, e.g. setting a heap size than 1.5GB on a 32-bit machine, etc. As you said, if you're not seeing any log files generated, then the java isn't even getting started, so it could be several factors, not the least of which is an invalid path to the JVM or the Tomcat jar files, etc. Jeff - 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

Re: unable to start Tomcat through the Windows Services panel
I remember installing an older version of Tomcat some years ago and it had a Setup.exe or Install.exe program in its library which invoked the Windows installer and installed it as a service. Some of the documentation for version 7 mentions the Windows installer but does not provide a link or gives an actual name. In some other part of the documentation it says to download the binary version and expand it in its own directory, which I did, but I can not find a Windows program that will install it and set it up as a service.

Tomcat classloader memory leak when an object is stored into session
When an application stores an object into the session and then the
application is reloaded using Tomcat Web Application Manager, the
classloader cannot be garbage collected. As a result, the
OutOfMemoryError: PermGen space error occurs after several reloads.
To illustrate the issue, you can find an example below.
Thanks in advance :-)
1. The EvilClass class whose instances are stored into the session:
public class EvilClass implements Serializable {
// Eat 100 MB from the JVM heap to see that the class is not
garbage collected
protected static final byte[] MEM = new byte[100 20];
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
2. Servlet which stores EvilClass instances into session
public class TestServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse
resp) throws ServletException, IOException {
EvilClass obj = new EvilClass();
obj.setValue(req.getRequestURI());
req.getSession().setAttribute(test, obj);
getServletContext().log(Attribute stored to session + obj);
}
}
3. web.xml part which maps the servlet to an URL
servlet
servlet-nameTestServlet/servlet-name
servlet-classtest.TestServlet/servlet-class
/servlet
servlet-mapping
servlet-nameTestServlet/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
Steps to reproduce the issue:
1. Copy application WAR to the webapps directory.
2. Start Apache Tomcat.
3. Hit TestServlet.
4. Check Heap/PermGen size using Java VisualVM.
5. Reload the application thru Tomcat Web Application Manager.
6. Hit TestServlet again.
7. Perform GC and check Heap/PermGen size again.
Environment:
Apache Tomcat version: 7.0.50
OS: Windows 7 64
JVM: Java HotSpot(TM) 64-Bit Server VM (23.6-b04, mixed mode)
Java: version 1.7.0_10, vendor Oracle Corporation

Tomcat JNDI Datasource
I have defined a JNDI JDBC datasource as a resource in the global context.xml file. I was under the impression that what this does is to create a shared connection pool that is tomcat wide. But in practice what seems to happen is that a new instance of that connection pool is created for each context that is running in the container. For example, if I have 6 web applications deployed I end up with 60 connections to my database, assuming the default initialSize parameter of 10. Is there a way to have a single connection pool that is shared amongst deployed applications? In case it is relevant this is tomcat 7.0.19 using the tomcat connection pool. Thanks -Dave
Re: Tomcat JNDI Datasource
Yes, define the connection pool in server.xml, GlobalNamingResources then in context.xml define a ContextLink That binds the shared connection pool to each context.

What is the best connector configuration for thousands of mostly idle users?
Problem summary: My nio polling threads are using too much CPU time. Application overview: My application has from 1,300 - 4,000 users connected at any given time. Each user sends about 200 bytes, then waits 30 seconds, then sends about 200 bytes, and this just loops for each user. Each user connects with SSL, and we use a long keepalive to ensure that the HTTP connection doesn't close, so that we don't have to renegotiate SSL. Configuration: Ubuntu 12.0.4 with Tomcat 7.0.35, 1.75 gigs of RAM. We are using Apache with SSL and mod_proxy_ajp to forward requests to Tomcat. It has MPM module enabled, with 500 ThreadsPerChild, so we typically have from 3-9 Apache instances running. IfModule mpm_worker_module ServerLimit 12 ThreadLimit 1000 StartServers 1 MinSpareThreads 25 MaxRequestsPerChild 0 MaxSpareThreads 500 ThreadsPerChild 500 MaxClients 5000 /IfModule ProxyPass /WSMRegister ajp://localhost:8009/WSMRegister We are using the AJP NIO connector on port 8009 on Tomcat with 15 worker threads: !-- Define an AJP 1.3 Connector on port 8009 -- Connector port=8009 protocol=org.apache.coyote.ajp.AjpNioProtocol redirectPort=8443 minSpareThreads=1 maxThreads=15 scheme=https secure=true URIDecoding=UTF-8 proxyName=secure2.360works.com proxyPort=443 / Problem detail: lsof is currently showing 564 open sockets between Apache and Tomcat on port 8009, with 1,352 users connected to Apache. The two threads consuming the most CPU time in Tomcat are NioBlockingSelector.BlockPoller-2 / 15 and ajp-nio-8009-ClientPoller-0 / 25. Between them, they are taking 20% of all CPU time for the Tomcat process. I get a few times a day when our monitoring software reports slow response times, and I'd like to solve this. Some guesses at solutions: I'm guessing that the high CPU usage is because they are polling all 564 open sockets constantly? Would it make sense to reduce the number of open sockets? I didn't configure any maximum and I don't know how to reduce this number. I'm also concerned that reducing that might negate any benefits by increasing the number of sockets opening and closing between ajp_mod_proxy and the NIO AJP connector. Maybe it's already running at optimal performance and I just need to throw hardware at it, but it seems like a solvable problem, because the actual worker threads are not doing much at all. --Jesse Barnum, President, 360Works http://www.360works.com Product updates and news on http://facebook.com/360Works (770) 234-9293 == Don't lose your data! http://360works.com/safetynet/ for FileMaker Server == - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
SSL with Form Fallback on Tomcat 7 or 8
Evening, I've been reading this page: http://wiki.apache.org/tomcat/SSLWithFORMFallback I'm currently using Tomcat 7 on Linux. In short, Neither of the bits of code linked on that page work for me but the thing described in the title is what I desire. I have client certificate authentication working fully within my needs, but I'm looking for a fallback so I can support allow users without one of the appropriate smart cards being able to get in. BasicAuth would also be fine for this project, although I'd much rather it were a form. Additionally, I'm unclear on what the purpose of optional is on the clientAuth parameter of a Connector,if it's not for the purpose of some other fallback authentication mechanism to work. Maybe it's just implemented because it's integral to the TLS implementation? Another option is to configure the trust store appropriately, then self-sign certificates and pass them out. That's still a little hostile to the users that don't have smartcards in the first place; I have my Realm hitting up an LDAP server with a username-pass tuple that non-smartcard-wielding users already have an account on. Any suggestions or direction would be greatly appreciated; fundamentally, I have an app, using container security to keep it safe. Most users will use smartcards to secure a client cert TLS, but not all users have those smartcards.

This is true. What is your question?
To illustrate the issue, you can find an example below.
Thanks in advance :-)
1. The EvilClass class whose instances are stored into the session:
public class EvilClass implements Serializable {
// Eat 100 MB from the JVM heap to see that the class is not

protected static final byte[] MEM = new byte[100 20];
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
2. Servlet which stores EvilClass instances into session
public class TestServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req, HttpServletResponse
resp) throws ServletException, IOException {
EvilClass obj = new EvilClass();
obj.setValue(req.getRequestURI());
req.getSession().setAttribute(test, obj);

7. Perform GC and check Heap/PermGen size again.

But do you have to serialize your sessions? Switching off session
serialization might help.

Application overview: My application has from 1,300 - 4,000 users connected at any given time. Each user sends about 200 bytes, then waits 30 seconds, then sends about 200 bytes, and this just loops for each user. Each user connects with SSL, and we use a long keepalive to ensure that the HTTP connection doesn't close, so that we don't have to renegotiate SSL. How long should the application take to process those 200 bytes? I'm wondering what the peak number of concurrent requests, rather than connections, might be. Configuration: Ubuntu 12.0.4 with Tomcat 7.0.35, 1.75 gigs of RAM. We are using Apache with SSL and mod_proxy_ajp to forward requests to Tomcat. It has MPM module enabled, with 500 ThreadsPerChild, so we typically have from 3-9 Apache instances running. IfModule mpm_worker_module ServerLimit 12 ThreadLimit 1000 StartServers 1 MinSpareThreads 25 MaxRequestsPerChild 0 MaxSpareThreads 500 ThreadsPerChild 500 MaxClients 5000 /IfModule ProxyPass /WSMRegister ajp://localhost:8009/WSMRegister We are using the AJP NIO connector on port 8009 on Tomcat with 15 worker threads: !-- Define an AJP 1.3 Connector on port 8009 -- Connector port=8009 protocol=org.apache.coyote.ajp.AjpNioProtocol redirectPort=8443 minSpareThreads=1 maxThreads=15 scheme=https secure=true URIDecoding=UTF-8 proxyName=secure2.360works.com proxyPort=443 / Problem detail: lsof is currently showing 564 open sockets between Apache and Tomcat on port 8009, with 1,352 users connected to Apache. The two threads consuming the most CPU time in Tomcat are NioBlockingSelector.BlockPoller-2 / 15 and ajp-nio-8009-ClientPoller-0 / 25. Between them, they are taking 20% of all CPU time for the Tomcat process. I get a few times a day when our monitoring software reports slow response times, and I'd like to solve this. How much actual processor time are those threads taking? The 20% is only relative and it would be helpful to know what it is relative to. Do you have access logs available for those times? The number of concurrent requests would be a useful number. When working that out you need to be sure if the time in the access log is the time the request started or the time it finished. Some guesses at solutions: I'm guessing that the high CPU usage is because they are polling all 564 open sockets constantly? Would it make sense to reduce the number of open sockets? I didn't configure any maximum and I don't know how to reduce this number. I'm also concerned that reducing that might negate any benefits by increasing the number of sockets opening and closing between ajp_mod_proxy and the NIO AJP connector. Some rough numbers. With a peak of 9 httpd children with 500 threads each - assume at least 4000 connected clients. With a request every 30 seconds that is roughly 133 requests a second assuming they are perfectly evenly distributed which they won't be. With 15 worker threads on Tomcat each one will be handling roughly 9 requests a second, again assuming even distribution. That means a request has about 110ms to complete or you run the risk of running out of threads. This includes the time to process the request and a little overhead for Tomcat to recycle the thread. I wouldn't be surprised for peak loads to be at least 2-3 times higher due to the uneven distribution of requests in time. That means requests have more like 35-40ms to complete. I suspect that you are running out of worker threads on the Tomcat side. Increasing it from 15 to 30 wouldn't do any harm. Of course, this is just guess work. You'd need to look at your access logs to be sure. Maybe it's already running at optimal performance and I just need to throw hardware at it, but it seems like a solvable problem, because the actual worker threads are not doing much at all. I agree it sounds like configuration at this point. Mark - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
Re: Tomcat classloader memory leak when an object is stored into session
Michal Botka mr.bo...@gmail.com wrote:
Is there a way how to avoid this leak?
I would like to develop an application which can be safely
deployed/undeployed without restarting the server.
OK, now I know that my application cannot store it's objects into
session, but that is very strong requirement which the most of the
applications don't meet.
The leak, as described, should not happen.
The sessions are serialized to disk. That disconnects the objects in the
session from the web application class loader. When they are deseralized it
will be with the class loader of the new web application.
Therefore, objects in the session should not be retaining references to the old
web application class loader.
I need to run through the provided test case to see if there is something going
wrong but at this point I strongly suspect that the source of the leak is
something else entirely (most likely a leak in a 3rd party library or possibly
an application bug).

Thanks for help.

This is true. What is your question?
To illustrate the issue, you can find an example below.
Thanks in advance :-)
1. The EvilClass class whose instances are stored into the session:
public class EvilClass implements Serializable {
// Eat 100 MB from the JVM heap to see that the class is not
garbage collected
protected static final byte[] MEM = new byte[100 20];
private String value;
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
}
2. Servlet which stores EvilClass instances into session
public class TestServlet extends HttpServlet {
@Override
protected void doGet(HttpServletRequest req,
HttpServletResponse
resp) throws ServletException, IOException {
EvilClass obj = new EvilClass();
obj.setValue(req.getRequestURI());
req.getSession().setAttribute(test, obj);
getServletContext().log(Attribute stored to session +
obj);
}
}
3. web.xml part which maps the servlet to an URL
servlet
servlet-nameTestServlet/servlet-name
servlet-classtest.TestServlet/servlet-class
/servlet
servlet-mapping
servlet-nameTestServlet/servlet-name
url-pattern/*/url-pattern
/servlet-mapping
Steps to reproduce the issue:
1. Copy application WAR to the webapps directory.
2. Start Apache Tomcat.
3. Hit TestServlet.
4. Check Heap/PermGen size using Java VisualVM.
5. Reload the application thru Tomcat Web Application Manager.
6. Hit TestServlet again.
7. Perform GC and check Heap/PermGen size again.
Environment:
