Tomcat security realms question
Hi all I have a problem that's been raised by my security team to do with using Tomcat JDBCRealms. We're using such realms to protect restricted resources. We also have a custom login form. The steps Tomcat seems to follow when using such a setup is: 1. Check to see if the user is logged in with access to the restricted resource. 2. If they aren't, forward them to the login page and create an HTTPSession to keep track of that user. 3. Once they've logged in, add the authentication system to the HTTPSession created in step 2 to hold that info and forward them to the resource. 4. Continue using the same HTTPSession to maintain state. The problem my security team has with this is that someone could potentially steal the users HTTPSession ID before they've logged in, as this is created in the login screen. e.g. the user is forwarded to the login screen, then goes to make themselves a cup of coffee. A hacker goes to their computer and writes down the session ID. The user comes back and logs in, and the hacker pretends to be them from another computer. My question is: how can I avoid this situation and keep the security guys happy? Is it possible to have the session ID held by the browser (in JSessionID) change post-login (ie make tomcat invalidate the current session and create a new session after the user has been successfully authenticated)?

Re: session replication problem: ClassCastException
Hi Peter, thank you very much for your quick response! I have more information on this topic now. Peter Rossbach wrote: First your are sure that your wars inside the installation art identical? Yes I am. Our automated install procedure ensures that. You stacktraces are strange. The cast inside writeSession use only tomcat classes! Have you change the authorisation and use your own principal implementation ? No. We did no such changes. I already thought it might have something to do with different Classloaders used by the two tomcats, but I know too little about the Classloaders that tomcat uses to judge this suspicion. For more help I think do the following steps a) update to tomcat 5.5.9 b) install the cluster fix ( The Bug Database http://issues.apache.org/bugzilla/show_bug.cgi?id=34389) c) change your Cluster Config from SimpleTcpReplicationManager to DeltaManager d) Use fastasyncqueue mode. We die the same modifications to our testcluster now. Because the configuration files are autogenerated i am sure that the config files are the same except the details that have to be different (like machine names etc.). Besides that we have exactly the same software (webapp) running on the testcluster. The interesting part is that we do not see these ClassCastExceptions in the testcluster? I originally thought that it might be that we got something wrong with the tomcat set-up and i've reinstalled tomcat 5.5.4 plus jdk1.4 patch on the production machines but this did not help. We also noticed that these class cast exceptions do not depend on the numbers of sessions we have. They are roughly constant at roughly 2 such exceptions per minute, even during the night where our session count drops to basically 0. We currently cannot upgrade to tomcat 5.5.9 because of our upgrade policy to only upgrade software when it was extensively tested in our test environment. Via Google I only found one post with a remotely similar problem: http://www.junlu.com/msg/65888.html otherwise I have no more Ideas on how to continue from here. Do you see any other way how to analyse and debug this problem?

Re: out of memory error while load testing
I forgot to give details about my Application and test. These details might give you people an idea about the problem area. In this app. users has to enter login ID and pwd in home page which will be sent to a resource which validates these details, say "LoginValidation" this resource will then forward control to the Main Page of the Application, say "MainPage.jsp" . From main page user can open/ request different pages(modules of application). But my test only involves a request to "LoginValidation" followed by request to main page. In this app. inorder to get data about certain activities happening on the server side into the client browser, we keep on refreshing a hidden frame in mainpage (simply using html meta refresh ) after every one minute, lets call this page as PollServerForData.jsp. To simulate this i added a request to PollServerForData.jsp also in my test plan after request to the main page (that means every virtual user will be requesting the PollServerForData.jsp page after every one minute) This test worked for 1200 virtual users and failed for when tried with more than 1200 users . Will there be any problem for tomcat for maintaining more than 1200 sessions in memory?? regards Srikanth.P On 7/14/05, Bhaskar <[EMAIL PROTECTED]> wrote: > You need to check on whether it is giving Outofmemory error is > immediately after starting loadtesting with 1500 users or over period of > time.

Re: out of memory error while load testing
Hi, Its giving out of memory over a period of time (i.e after test ran for some time ) not immediately after starting the test Follwing settings are given in my server.xml For HTTP For HTTPS By active threads do u mean the thread count shown in windows task manager or is there any way to find out active threads in Tomcat? what is this Performance-Valve? can u give some more details on it ?

Re: Production cluster crashed with 'SEVERE: TCP Worker thread...' error
Several minutes before the crash, I found some session replication error.
That seemed to cause all my JK connector threads being hold up and no
responding to further requests.

According to the spec (section 8.2 for those of you following along at home
:), the only safe HttpServletRequest to pass is the one that was passed into
the Servlet, or a child of HttpServletRequestWrapper that wraps the one that
was passed into the Servlet.
Tomcat happens to be very lenient in inforcing this restriction among
Servlet-Containers out there. The other-guys would probably throw an
exception straight away for attempting something like the above.

Starting Tomcat 5.0.19 without the console
Hi - I'm trying to use the "javaw" option in catalina.bat to kick off Tomcat without opening a console window. Besides not having an always open command prompt window (console) I hope to get the various messages which print to the console to go into the standard log. I've been experimenting with the FileLogger settings but not having any success. I've set SwallowOutput to "false" in hopes of seeing console messages appear in a log file someplace as well. I'm using Tomcat 5.0.19 on Windows 2000 with JDK 1.4.2. I need to start Tomcat from a .bat file since I have extensive extra class files and configuration to call and that does not seem possible when running Tomcat as a service using the default installation setup.

RE: RFC-2047 Header Character Set Encoding JK + Tomcat 5
For others who might be interested- and the tomcat developers should correct me if I'm wrong since this goes into the archive, Tomcat 5.5.9 or < does not appear to support RFC-2047 for processing MIME-Headers that use different character encodings besides ISO-8859-1. Searching through 1000's of lines of tomcat code, as best I could tell, the code always assumes headers are of ISO-8859-1 type... from the MimeHeaders class down to the ChunkByte class. While both appear to have the ability to specify encoding, they correctly assume the default to be ISO and from what I could tell, the code parsing headers from the Request does nothing to change this. I could find no provisions for processing RFC-2047 compliant headers in any of the connectors. Listed here: http://www.faqs.org/rfcs/rfc2047.html and referenced from the HTTP 1.1 RFC listed here: http://www.faqs.org/rfcs/rfc2616.html (see section 2.2 on basic rules for TEXT, and the definition of headers in section 4.2) and references in JSR-154 servlet 2.4 spec. Is Tomcat still considered a reference implementation? I hope this helps all who run into similar issues and can find no information on them. Now on to the Apache 2 source code to see if it specifies the format required in the Header module API. Byron Keywords: International Headers UTF-8 ISO-8859-1 RFC-2047 -Original Message- From: Guernsey, Byron (GE Consumer & Industrial) Sent: Tuesday, July 12, 2005 4:16 PM To: Tomcat Users List Subject: RFC-2047 Header Character Set Encoding JK + Tomcat 5 Is there a FAQ on how Tomcat 5 and JK1 implement HTTP header character sets? (ie, does it support RFC-2047) We use some single sign-on plugin's at the web server (apache 2) that set specific headers which may contain international characters. The headers are being returned by Tomcat to jsps/servlets in such a way that the strings decode properly only if the browser is forced to view them as UTF-8. This implies that the values are actually UTF-8 encoded, but improperly assumed to be ISO-8859-1 as some point. I have not yet tracked down which component in the chain is at fault. It may very well be that the SSO plugin is calling the Apache API to set Headers with UTF-8 values when they accept only ISO-8859-1 values, or values encoded per RFC-2047. I'd like to find out what mod_jk expects the header values to be when it retrieves them from Apache, and whether Tomcat supports RFC-2047 decoding of header values. If anyone has any experience with this, or can refer me to a discussion or thread about this very item, I'd greatly appreciate the tip. I'm not looking forward to the amount of inspection I'm going to have to do to find the culprit. thanks, Byron - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Actually, a given servlet object may be accessed by multiple request-processing threads simultaneously.

Re: mod_jk - multiple workers for same Tomcat instance?
Hi, We have set up several contexts eg one for client requests and one for admin requests, for a set of Tomcat servers, fronted by Apache. We would like to balance them differently, allowing one machine to take most of the admin load. There doesn't seem to be a lbfactor parameter for a loadbalancing worker, so our second option is to create a seperate client and admin worker for each machine, and set their lbfactors separately. Unless you can recommend a better way? If we go down this route, could you explain how to set up two connectors in the tomcat's server.xml with different jvmRoute values to put in workers.properties? many thanks, David From: Mladen Turk <[EMAIL PROTECTED]> Reply-To: "Tomcat Users List" To: Tomcat Users List Subject: Re: mod_jk - multiple workers for same Tomcat instance?

OracleDataSourceFactory
In the ever confusing quest to properly create an Oracle data source in
Tomcat 5.5.x using the 10g JDBC drivers, I am stuck trying to properly
configure connection caching. I've tried the following in my context XML
file...
...but when I retrieve the data source in my code and examine it...
OracleDataSource ods = (OracleDataSource)m_dataSource;
message.append("\nExtended Oracle data source information");
message.append("\nName:" +
ods.getDataSourceName());
message.append("\nDescription: " +
ods.getDescription());
message.append("\nCaching enabled: " +
ods.getConnectionCachingEnabled());
message.append("\nImplicit caching enabled:" +
ods.getImplicitCachingEnabled());
message.append("\nExplicit caching enabled:" +
ods.getExplicitCachingEnabled());
message.append("\nFast Failover enabled: " +
ods.getFastConnectionFailoverEnabled());
message.append("\nConnection cache properties: " +
ods.getConnectionCacheProperties());
...I get the following inconsistent results...
Extended Oracle data source information
Name: OracleDataSource
Description:null
Caching enabled:true
Implicit caching enabled: false
Explicit caching enabled: false
Fast Failover enabled: false
Connection cache properties: {MaxStatementsLimit=0,
AbandonedConnectionTimeout=0,
MinLimit=0, TimeToLiveTimeout=0, LowerThresholdLimit=20, InitialLimit=0,
ValidateConnection=false,
ConnectionWaitTimeout=0, PropertyCheckInterval=900, InactivityTimeout=0,
ClosestConnectionMatch=false,
MaxLimit=2147483647, AttributeWeights=NULL}
...that show that the data source is correct and the
connectionCachingEnabled property is getting through. But I can't seem
to set any of the other properties, most importantly the maximum number
of connections for the pool. So I have a few questions...
Is this is latest and greatest way to properly create and configure an
Oracle data source in Tomcat?
How does Tomcat go about creating the data source and how does it decide
what properties to set on the data source?
Is there a definitive list of properties for the Oracle data source?
Thanks,
Bernie Durfee

Re: Session Mixup
Ok. One other thought that's burned me once -- servlet instances are recycled between requests without resetting any of it's field members. The next request gets it exactly as the one before left it. That means you should either avoid field members in favor of method parameters + method local variables or be sure to reinitialize them before processing a new request. --David Srinivas Gunturu wrote: All 6 of us are logging simultaneously from different machines.

In theory, yes, by using the disallow directive appropriately. For example, this snippet recommends all bots stay away from your CGI scripts.

Re: What is allowed to do with a HttpServletRequest ?
The question is probably : "why do you need to refer to the first
request ?". Dont you need to actually refer to some state of the
request ? Could you extract that state from the request instead of
storing the full request ?
Maybe I'm just asking a dumb question, but I have problem
understanding why you would need the whole request ...

How to Replace Tomcat authentication?
Hi, I've been looking into possibly replacing Tomcat's authentication with our own functionality. It looks like there use to be a class called SimpleRealm in the older Tomcat versions that would have done the trick if we replaced it, but I can't find any references to it in the latest source that I downloaded. Has anyone here done this before, and can you provide me to some pointers as to where/how to get started with it with the current version of Tomcat? Thanks in advance!!

Re: Tomcat Configuration
Do you have a web.xml in WEB-INF? What do the tomcat logs say on startup? You can tweak the logger verbosity by increasing the debug attributes on elements within server.xml. What version of tomcat? Not sure Logger elements are supported in 5.5.x Jon PS: books are generally out of date by the time they are published ;) There are plenty of config changes between 4.0.x, 4.1.x, 5.0.x and 5.5.x versions Iin Nurhidayat wrote: yess --- "Raghupathy,Gurumoorthy" <[EMAIL PROTECTED]> wrote: Did you restart tomcat ? -Original Message- From: Iin Nurhidayat [mailto:[EMAIL PROTECTED] Sent: 14 July 2005 13:30 To: Tomcat Users List Subject: RE: Tomcat Configuration Hi Guru, i replced webapps but i have same problem also ...

Re: Trying to configure apache, tomcat and mod_jk
Thanks to Paul Constantine and Alan Chandler for their responses. I've managed to get it all working (eventually!). I think there were two stumbling blocks: 1. I had rebuild Apache but was accidentally running the old version, so the httpd.conf was not being picked up. 2. Paul's blog clarified which settings I should be using in server.xml. I've tried to record exactly what I did here: http://philoxenic.blogspot.com/2005/07/setting-up-tomcat.html.

Re: out of memory error while load testing
You need to check on whether it is giving Outofmemory error is immediately after starting loadtesting with 1500 users or over period of time. If it is over period of time then you need to check whether there are any memory leaks. Or your design for ex., it might happen if you query db and that ends up resulting in huge number of rows. BTW., what is the max number of threads you have configured? and what is the active number of threads? Pbly u can use Performance-Valve to get such details.

org.apache.catalina.util.ParameterMap.put exception
Hello all I receive the following exception in a non deterministic manner. The reader should understand that the exception is not thrown due to my direct action on a ParameterMap instance. Is there any possibility of knowing what to do in this case ? - BEGIN EXCEPTION - HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception java.lang.IllegalStateException: Cannot find message associated with key 'parameterMap.locked' at org.apache.catalina.util.ParameterMap.put(ParameterMap.java:212) at org.apache.coyote.tomcat4.CoyoteRequest.getParameterMap(CoyoteRequest.java:937) at org.apache.coyote.tomcat4.CoyoteRequestFacade.getParameterMap(CoyoteRequestFacade.java:193) at org.apache.catalina.core.ApplicationHttpRequest.setRequest(ApplicationHttpRequest.java:525) at org.apache.catalina.core.ApplicationHttpRequest.(ApplicationHttpRequest.java:125) at org.apache.catalina.core.ApplicationDispatcher.wrapRequest(ApplicationDispatcher.java:921) at org.apache.catalina.core.ApplicationDispatcher.doForward(ApplicationDispatcher.java:414) at org.apache.catalina.core.ApplicationDispatcher.forward(ApplicationDispatcher.java:356) at mypackage.Hello.showResult(Hello.java:167) at mypackage.Hello.doGet(Hello.java:194) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) . . . - END EXCEPTION - - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Nested Web applications.
Hi all, I have multiple web applications. Currently all of them are distributed as WAR files and each one has a web.xml file with its own configurations. When they are installed, a separate directory for each is created in the /webapps folder. These applications are currently working fine. Now I want to integrate all these application into one. This application when installed using its WAR file will create a folder in /webapps say /mainapp. This will contain just one initialization servlet and its directory structure will look as follows /webapps/mainapp/apps /webapps/mainapp/apps/webapp_1.war /webapps/mainapp/apps/webapp_1 /clientcode /lib (3rd party client libraries) /icons /logs /WEB-INF /web.xml /classes (inhouse server classes) /lib (3rd party server libraries) /webapps/mainapp/apps/webapp_n.war /webapps/mainapp/apps/webapp_n /clientcode /lib /icons /logs /WEB-INF /web.xml /classes /lib /webapps/mainapp/common /webapps/mainapp/common/classes (inhouse common client classes) /webapps/mainapp/common/icons /webapps/mainapp/common/lib (3rd party common client libraries) /webapps/mainapp/license /license.dat (This will determine which webapp to install) /webapps/mainapp/WEB-INF /web.xml /classes (inhouse common server classes) /lib (inhouse and 3rd party common server libraries) The main application WAR file will contain all the other WAR files in its /app folder. Each of the other applications will have an initialization servlet and their servlet names would be configured in the main application's web.xml file. How can a servlet tell Tomcat to expand the WAR file and install web applications under it?

There is a simple program (in windows, but perhaps in Linux too) that is able to prepare some html pages with a little bit of javascript. It is called Irfanview or something like this...

Putting JNDI configurable info. inside of a properties file only
Dear List, In the example docs on the Apache web-site, all the JNDI info. is configured inside of the server.xml and web.xml. Is it possible or better said "usual" to make a data source, with the Oracle configurable JDBC URL connection info. in a separate properties file. This would mean that the JNDI info. is isolated from the web application itself, and means the web administrator need not ediit the server and web.xml files. Is this a reasonable request ?
