I'd like to take this opportunity to publicly thank Warren for taking the time to work with me on this when he had a lot more important things to do than answer my questions. The manager application was installed with a user name and password that the attackers were able to brute force. Once they had access to the manager application they were able to install their own web application that allowed them wider access to the box. This isn't the first report of a rouge application that we have seen on the Tomcat security list. Where we have had sufficient detail to trace how the application was installed, it has always been via an existing management tool. Therefore, I would like to take the opportunity to remind users to ensure that any potentially user accessible administration interface is suitably secured. The following isn't an exhaustive list but things to consider include: - don't use and standard user names for administrative users - do use strong passwords, especially for administrative users - uninstall web applications you don't need (admin, manager, host-manager, examples, webdav, etc) - use Remote Host/Address filters to limit access to administrative applications - enable access logging so if something does go wrong you have some information to work with - regularly review your access logs for evidence of potential attacks - run Tomcat as a dedicated user with the minimum privileges possible Finally, a small advert.

You can write a simple JSP which will run a freeMemory/totalMemory call in your JVM and possibly send a mail/log when the limits are reached. You could set a refresh interval and have this page refresh say every 5 minutes in your browser. Alternatively you can tweak with the manager app code.

However with the latest set of upgrades rather forced upon me all at once (instead of managed more properly), my application appears to have a severe memory leak. System Info: OS is Solaris 10-u5 (2008); java 1.6.0_06-b02; apache-tomcat-6.0.16; mysql 5.0.51a-solaris10-x86_64. I have fast servers and plenty of memory (8 gigs). I'm running 1 gig stack and getting at least 2 GC/stack exceptions per day (sometimes more). Yes - it's a user/use triggered leak but I can't trace it further yet. Of course what is odd is that there was NO memory leak using older versions of this stuff (Solaris 10 (2006), java 1.5.x, tomcat 5.5.12, mysql 5.0.16). I'm sure the memory leak was there, but it was well masked. On the older system I was running 512 meg stack and it never gave GC or stack errors. So, while I am actively trying to fix the memory leak, I still have to maintain these production servers at operatonal status (politics - don't ask). However, it's difficult as the memory leak is causing repeated GC and out of stack exceptions. What I've noticed recently is that when using the manager application, I can watch the memory utilization grow and more memory get allocated (via refreshing the page), right up until the stack is used up and the main application crashes. However, if I'm watching it grow, and then log on to the server and reset tomcat (stop and then start tomcat), the memory use is back at the start. Thanks to session persistence, no users are harmed during this exercise. So for the moment, while I try and debug the application, I can keep things running by having a cron job periodically reset tomcat for me. But this is really crude. Until I fix the memory leak, I'd like something a little bit more elegant. SO - my question - is there a relatively easy way to create something (say a servlet) to watch the stack *just like I can do manually using the manager application* but email me when the stack approaches the memory limits?

As I see it you are mixing two different things, your web application will always run inside Tomcat server but your desktop application can be anywhere(not just on TC server). The simplest way to do this might be to write your own database connection helper class which would go to the context (step 6) and use Tomcat datasource to get connections when you are running under TC. And in desktop mode you have your own connection pooler (or just create a simple db connection ) to get a db connection. so your getConnection method on helper would do the following logic : Is in desktop mode yes get my pooler/connection else //under TC get connection with logic as in step 6 -Sameer --- On Wed, 7/23/08, Alejandro Hernandez Angeles [EMAIL PROTECTED] wrote: From: Alejandro Hernandez Angeles [EMAIL PROTECTED] Subject: Trying to mix db connection pooling on web and desktop applications To: users@tomcat.apache.org Date: Wednesday, July 23, 2008, 1:21 AM Hello, this is the scenario: I have an application that must have two interfaces: as a desktop application and as a web application I've put the business logic inside a JAR library (client_bpm.jar), which must connect to an Oracle 9i database I configured the web application so it can use a db pool connection, in the following manner: 1.

Re: DataSourceRealm documentation
It means that on whichever database you are using to store your authentication information you need to create a user id and password for Tomcat to connect to it and then read the information. Your database doc. will give instructions on creating user/pass on it. For eg. you can create user/password as tcuser/mypassword. You then need to configure a Datasource in Tomcat which can be used by Tomcat to connect to this database and read the proper tables for authentication. Read the Datasource related docs. http://tomcat.apache.org/tomcat-5.5-doc/config/realm.html These instructions are for authentication information stored in a relational database that can be accessed by proper JDBC driver an example would be MySQL.

Hi, Directories and Web Applications are different things. In case of Tomcat , a directory is created for each web application deployed on the server, all these go under the webapps directory. so for example you have 2 applications say app1 and app2 running inside Tomcat then you will see two directories under your webapps : webapps | - app1 (you can have directory under these, that will depend on your app. needs) | - app2 You can create more directories under your application directory if you want , depends on what your needs are.

Re: How can applications be isolated in Tomcat?

The problem is that I don't know what needs changing in the startup.sh or whatever. The application is deployed on linux runing Fedora Core 4. Could someone give me an idea what I need to edit.

Re: Install on XP Home edition
Open a command prompt and then try manually running the Tomcat startup batch file, you should be able to see the error message.

Re: How to do the precompilation on jsp
My understanding is that you need to pre-compile jsp's from your build before you start using the application right ? You can write a simple script to hit all your jsp's ( need to start tomcat first), this will precompile your jsp's. -Sameer Raju Balugu [EMAIL PROTECTED] wrote: Hi All, We are using the clearcase for version control(vob).My requirement is like..I need to do the precompilation before going to ran a build?is there any utilities in tomcat end or third partys.(as the jasper-compiler is so fast we are palning to do this).please share your experience on precompile the jsp files Thanks in advance.

Re: query
Oracle also installs its own jdk and may have changed the environment settings have you checked the java version at command prompt. Notmally Oracle jdk is 1.3 and installed inside Oracle home dir. Also you may want to try running tomcat from command prompt, it may show some errors. -Sameer veena v [EMAIL PROTECTED] wrote: There is no error message.

Re: When does the MarkSweepCompact Garbage Collector perform GC?
Check out this link might answer few of your queries. http://java.sun.com/docs/hotspot/gc1.4.2/faq.html -Sameer Benjamin Chu [EMAIL PROTECTED] wrote: Hello! Now I am using the jconsole to monitor the heap memory usage of the tomcat 5.5. I've constructed a testbed to test the performance of the applications running on the tomcat. However, the jconsole shows that the MarkSweepCompact Garbage Collector never does its job. The only two ways to make this garbage collector to perform GC are: 1 I push the button perform GC shown on the Memory tab of the jconsole 2 I insert the code System.gc() into the servlets. I think both of these two ways are not good, and this garbage collector should perform GC automatically (in my opinion). I just wonder when or under which conditions the MarkSweepCompact Garbage Collector would perform GC. Or actually there is something wrong with my configuration so it doesn't perform GC?

Re: Tomcat Memory Leak
Did you try explicitly setting all those Hashmaps/Hashtables references to null. Since you already mentioned that your are taking care of all your Resultsets etc that doesent sound like an issue. I tried a small jsp example where I created a hashtable but never explicitly dereference it and the freememory seems to reduce continuosly. When I do a gc run though the memory seems to get freed. Hope this helps. -Sameer Petkov, Rossen [EMAIL PROTECTED] wrote: Hello, I am having a problem with Tomcat 5.0.19 on windows with JDK 1.4.2_03.The memory that java.exe is using keeps growing till the point that tomcat Runs out of memory. Using a profiler, doesn't seem to help me much. I can see the memory being used by certain classes go up (mainly char[] and byte[] and some tomcat classes, please see the tables below) and even reach all the way to the point that used java heap equals to the java heap, then GC probably kicks but, while running Tomcat throws an OutOfMemory exception. I have allocated -Xmx896M. I'm now forcing a GC when the free memory drops to 15%. With every GC, the freed memory is less and less, which to me is an indication of memory leak. I can't figure out where all those char[] objects are coming from or why they aren't being reclaimed by the garbage collector. I know that something is holding memory and isn't letting it go, and I know that the leaked memory consists of char[] and byte[] objects (see below tables). What I can't figure out is how to determine what's doing the leaking. After several hours of heavy usage, the GC runs and frees less memory than the previous run. This gives me on day of normal operation and I have to restart Tomcat after hours to be ready for the next day, not a really acceptable solution. I noticed the 3 tomcat classes: org.apache.tomcat.util.buf.MessageBytes, org.apache.tomcat.util.buf.ByteChunk and org.apache.tomcat.util.buf.CharChunk. The memory occupied my these seems to never be released. Can they be the cause of the multiple byte[] and char[]? Some info about the application/environment: - Tomcat 5.0.19 on windows with JDK 1.4.2_03. - MVC type web application - front Controller dispathing requests to business classes and forwards to appropriate JSP, passing necessary data objects in the request object - heavy JDBC use and DAO/DTO components, mainly using PreparedStatement - Oracle stored procedures and functions acccessed thru CallableStatement - Oracle database I am doing the usual for closing all jdbc database related objects like ResultSet, PreparedStatement and connections. Here are some thoughts that I have, that could be the reason for the leak, these are more questions: 1. DTO objects are being passed from the data layer to the business layer and finnaly to the JSP. After using the DTOs on the JSP, they are not explicitly set to null in the JSP. I see that all DTO declarations are in the service method of the compiled JSPs. Can this be a problem? 2. HashMaps, HashTables and LinkedHashMaps are being passed the same way thru the layers and end up in the JSPs. These are not set to null either. Can this be a problem? 3. PreparedStatement and CallableStatement are always closed, but not always set to null. Can any of these be the cause?

Re: Tomcat 5.0.28, Socket hanging on sending 20KB data for 16 minutes
Try synchronizing the code that uses Jfreechart classes. -Sameer Kumar Pandey [EMAIL PROTECTED] wrote: Hi I'm using Tomcat 5.0.26 that comes with JBoss 3.2.5 with default configurations A servlet creates pie/bar charts using JFreeChart. This is refreshed every 5 seconds via javascript refresh in the brower. All this has been workign fine for most customers. Suddenly for a specific customer sessions coming from a specific newtwork/georaphical location we see that the 5 seconds chart refreshes are hanging the thread. Charts are 20 KB. For a single user in the system sometimes these requests are talking up 20 ~30 threads and each stuck for 15~16 minutes before it finally clears up. We ran ethereal on the tcp packet and see that when the threads are hung, browser is sending FIN, ACK eventhough server hasn't completed sending the data. Thus we see TCP retranmissions of same packets as its not receiveing any ack from the client. How do I troubleshoot this issue. System is not memory starved and cpu is 98% idle. Any pointers on trouble shooting this would be greatly appreciated.
