Tomcat, Security, Anonymous Authentication
Hi, I have a question about the security issue that I have to cover of my server. I have web service which runs on Tomcat 5.5 with SSL ... I have installed all the SSL system on the server and it works fine, however as a little advance subject, I have to recover some security issues,... the first one is Disabling anonymous authentication ... I actually dont know the exact meaning of it an how to fix it... as far as foundfrom the web, I need to add some lines like SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!aNULL:!ADH:!ADH:!eNULL:!LOW:!EXP:RCA4+RSA:+HIGH:+MEDIUM to SOMEWHERE that I dont know and how... according to web site that I have inspired :) , those lines should be added to Apache/mos_ssl, httpd.conf, or ssl.conf ... but I dont have these files in tomcat directory... what should I do ? thank you... - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Hi David, First, it seems to not write all of the log entries. The final line is: [Sun Feb 12 21:14:08 2006] [warn] jk_uri_worker_map.c (42 This, I think, is normal. The logentries appear to be cached, and may therefore seem incomplete at any given time. Just wait a couple of minutes and you will find the line has been completed. [Sun Feb 12 13:34:23 2006] [error] jk_isapi_plugin.c (1049): could not get a worker for name ajp13 I've been having this error myself too. It seems that you MUST have a worker listed in worker.list called ajp13. I used to have one loadbalancing worker called wlb, which balanced between two workers ajp13 and backup. Still I kept getting this error. Finally I renamed the ajp13 worker to ajp13w and the loadbalancing worker from wlb to ajp13 and the error dissappeared. Looks like a bug to me. I've been Googling a lot for this error, and many forums contain posts reporting the same error, yet none of them have *any* replies.

RE: Tomcat5.15 basic setup question
You might consider the necessity of using port 8080 as well - client-side firewalls might block it, it is non-standard, and probably hard-coded everywhere along side the IP address. You can run Tomcat on port 80 (see the archives of this list--it has been discussed recently), or front with httpd (apache) and mod_proxy / mod_jk if (not strictly necessary, although it is still widely done.)

No, simple javac Hello.java doesn't work. Only if I set $CLASSPATH to /usr/lib/jdk/jre/lib/rt.jar or with the -cp-option. What environment variables do you have set? Do you mean $CLASSPATH?

No of concurrent requests per session
Hello: I am using Tomcat 5.0.30 with HTTP 1.1 Connector. If I try to make a third request while two other request's (which i have already made) responses have not yet arrived, then Tomcat is not serving the request until one of the pending response arrives. This limits me to only two pending requests (irrespective of the webapp) at a time. My front app is like a dashboard which integarates multiple web apps of which some are reporting apps which requires 4 to 7 minutes to process a request and some are data processing apps which requires only seconds to process the request. Assume the user clicks on two reporting links which open up as new windows from the main app window. Now when he clicks on another link irrespctive of the webapp, nothing happens until one of the reporting request's response is arrived. This problem appears only if the requests belong to the same session.

Re: problems with Clusters or apache connector not sure which one
I thought you said tomcat ran on 3 different boxes and it was a cluster ? java.io.IOException: Connection reset by peer This means that the tcp connection was severed somehow, this is typically caused by a firewall dropping idle TCP connections, or someone unplugging a network cable, or someone restarting something somewhere. You may want to configure apache to connect to 127.0.0.1 via the workers.properties file if you haven't already, as this will rarely never be firewalled, won't be subject to any link detection scripts, which may mark the interface as down when the link is severed, etc. etc. That's my two cents -Antony On 13/02/06, Randy Paries [EMAIL PROTECTED] wrote: i am the IT, the admin everything.

When this error happens, are you able to issue the command 1. to see if tomcat is listening, netstat -na |grep 8009 |grep LISTEN 2. if yes, try to connect to the socket telnet localhost 8009 on the box you see the error, this will tell you if the server socket is alright.

RE: jdbc context
Well, I guess it was my mistake. In Tomcat 5.5 you will be able to define the context information within each web app, by creating a context.xml in your war file, and the corresponding resource-ref in web.xml. Apparently this is not available in tomcat 4.1 I guess there are two options you may consider: One is to upgrade your tomcat to 5.5. The other is to change the web app not to use JNDI, but to use the data source factory directly in your code. Hope this helps.

RE: No of concurrent requests per session
I suspect the problem relates to pipelining of HTTP 1.1 requests over a single persistent TCP connection. Pipelining is intended to improve efficiency, allowing the need for multiple images to present a web page be expressed to a web server one after another, before any of the responses are given. However, the responses must be presented in the same order as the requests, and therein lies your problem. If your short running request is issued over the same TCP connection as one of the earlier, yet to be responded to, long running requests, the response to the later request must wait for the earlier request to be responded to first. In this scenario, you need to get either the browser or the web server to stop using persistent connections. Of course, this may make it less efficient for serving up normal web pages.

A single-user client SHOULD NOT maintain more than 2 connections with any server or proxy. IE implements this by default.

Since I wrote that peace of software I suppose I should know :) Anyhow there is only 'java' mode, not exe. For java mode you will need to edit the 'Argumets' (in the Startup tab) and add everything from JavaOptions, together with -classpath, so: -classpath C:\...\tomcat\bin\bootstrap.jar -Dcatalina.base=C:\...\tomcat -Dcatalina.home=C:\...\tomcat -Djava.endorsed.dirs=C:\...\tomcat\common\endorsed -Djava.io.tmpdir=C:\..\tomcat\temp start I'll probably fix the procrun, so that it uses JavaOptions and Classpath as Arguments for 'Java' mode.

c:forEach not working as expected
Hi List,
it seemed clear to me, that this construct:
c:forEach items=${t.records} var=x
... (some inner logic)
/c:forEach
should be equivalent to this one:
%
for (Iterator it=t.getRecords(); it.hasNext(); ) {
String x = (String)it.next();
%
... (some inner logic)
% }
%
But the forEach-version is not working as expected. What can be wrong?
Here are some quite strange effects:
1. The iterators-method hasNext() is called twice for every iteration
(ok: no problem, if the iterator is clean, but why?)
2. The loop-body is executed after hasNext() returned false.
But the next()-method is NOT called ??
The c:forEach-iterator seems to operate like this:
Iterator it = t.getRecords();
while (it.hasNext()) {
String x = (String)it.next();
boolean still_more = it.hasNext();
... here comes the body ...
}
What could this extra-check be good for?
Any help is greatly appreciated.
Kind regards,
Reinhard

Re: Encrypting ajp13 traffic
While I can't speak for the O.P., I have had need for this myself once upon a time.

My solution at the time was to setup a SSH tunnel between the two systems. It would be nice to have some form of encryption optionally available.

It has to do with the way the iteration code is divided between the
c:forEach and /c:forEach tags. I'm not sure if it *had* to be done
that way; you can dig into the Tomcat and JSTL source if you want to
redesign it. ;-)

Trouble accessing Resources in my Context
I'm running Tomcat 5.5.9 with JVM 1.5.0_05-83 on MacOS X 10.4.4. I'm
trying to build an example webapp that shows the configuration for
two Jackrabbit resources: one configured as an embedded resource for
that web app and another configured as a shared resource for the
entire host. I've tried to define the resources in a variety of
places and haven't been able to get any of them to work.
My context files are defined like this
$TOMCAT_HOME/conf/context.xml:
Context
WatchedResourceWEB-INF/web.xml/WatchedResource
/Context
webapp/WEB-INF/context.xml:
Context docBase=jackrabbit_config_test reloadable=false
Resource name=jcr/model1Repository
auth=Container
type=javax.jcr.Repository
factory=org.apache.jackrabbit.core.jndi.BindableRepositoryFactory
configFilePath=conf/repository_model1.xml
repHomeDir=shared/jackrabbit_model1 /
Environment name=testNum value=10
type=java.lang.Integer override=false/
/Context
I've got the following setup in server.xml:
GlobalNamingResources
...
Resource name=jcr/model2Repository
auth=Container
type=javax.jcr.Repository
factory=org.apache.jackrabbit.core.jndi.BindableRepositoryFactory
configFilePath=conf/repository_model2.xml
repHomeDir=shared/jackrabbit_model2 /
/GlobalNamingResources
And in my web.xml, I've got the following references:
web-app
...
resource-ref
descriptionJackrabbit Model 1 Repository/description
res-ref-namejcr/model1Repository/res-ref-name
res-typejavax.jcr.Repository/res-type
res-authContainer/res-auth
/resource-ref
resource-env-ref
descriptionJackrabbit Model 2 Repository/description
resource-env-ref-namejcr/model2Repository/resource-env-
ref-name
resource-env-ref-typejavax.jcr.Repository/resource-env-
ref-type
/resource-env-ref
resource-ref
descriptionTest Number/description
res-ref-nametestNum/res-ref-name
res-typejava.lang.Integer/res-type
res-authContainer/res-auth
/resource-ref
/web-app
I know tomcat is finding the jcr/model2Repository resource because if
I delete all of the database entries and repository files, and then
restart Tomcat, upon restart the database and repository files are
recreated. There's also log output in catalina.out about jackrabbit
initializing itself for the model2Repository.
When I get to my servlet, I've got some code that prints the context
entries for the initial context and the environment's context to the
output webpage. Then I try to access both repositories. For good
measure, I also try to access the testNum I defined in my webapp's
context.xml. None of the objects are accessible. The locally defined
objects (those in webapp/WEB-INF/context.xml) throw an exception:
javax.naming.NamingException: Cannot create resource instance
at org.apache.naming.factory.ResourceEnvFactory.getObjectInstance
(ResourceEnvFactory.java:99)
at javax.naming.spi.NamingManager.getObjectInstance
(NamingManager.java:304)

edu.ucsc.whisper.jackrabbit_test.JackrabbitTest.getObjectFromContext
(JackrabbitTest.java:85)
at edu.ucsc.whisper.jackrabbit_test.JackrabbitTest.doGet
(JackrabbitTest.java:54)
The shared repository object (defined in the server.xml and global
context.xml) simply comes back null when I call context.lookup( jcr/
model2Repository ) without throwing an exception.
I tried moving the configuration in the {webapp}/WEB-INF/context.xml
to server.xml's Host section, as below:
Context path=/jackrabbit_config_test
docBase=jackrabbit_config_test
Resource name=jcr/model1Repository
auth=Container
type=javax.jcr.Repository
factory=org.apache.jackrabbit.core.jndi.BindableRepositoryFactory
configFilePath=conf/repository_model1.xml
repHomeDir=shared/jackrabbit_model1 /
Environment name=testNum value=10
type=java.lang.Integer override=false/
/Context
Doing this made the servlet able to find the testNum environment
variable and the jcr/model2Repository was still null. But accessing
jcr/model1Repository seems to be worse because I got a ClassNotFound
exception on
org.apache.jackrabbit.core.jndi.BindableRepositoryFactory calling
context.lookup() on it. But the jackrabbit.jar is in both {webapp}/
WEB-INF/lib and $TOMCAT_HOME/server/lib, so I don't know why the
factory wouldn't be found. And, in the logs when the server starts
using this configuration, the jcr/model2Repository is still
App will work on localhost but blank on client PC.
I have a 2K3 Server on our intranet running Trend InterScan Messaging Security Suite which uses Apache Tomcat. I can access this app on the server through http://localhost:8447/ just fine. But when we try to access this app through a client connected to the 2k3s, we get a blank page with no error message, just one line of characters: _ [1][1] We've searched through Trend's support for this product and they don't have any suggestions except to make sure the redirects from IIS are there, which they are. Beyond that, they barely even mention Tomcat, so does anyone have an idea what may be wrong?

public void AuthenticatorBase.doLogin(request, response, principal)
Dear tomcat internals experts;
I'm taking a shot at prototyping a new method (yet untested) within
org.apache.cataline.authenticator.AuthenticatorBase:
public void doLogin(HttpServletRequest request, HttpServletResponse
response, Principal principal)
{
register(((CoyoteRequestFacade)request).request,
((CoyoteResponseFacade)response).response, principal, FORM, null, null);
}
This is intended to allow a webapp (one with access to the server
classes) to implicitly register a Principal with a http Session.
The above snippet doesn't compile because HttpRequest and HttpResponse
are protected fields.. is there a another way to achieve this?
Thanks,
ken

Pipelining is intended to improve efficiency, allowing the need for multiple images to present a web page be expressed to a web server one after another, before any of the responses are given. However, the responses must be presented in the same order as the requests, and therein lies your problem. If your short running request is issued over the same TCP connection as one of the earlier, yet to be responded to, long running requests, the response to the later request must wait for the earlier request to be responded to first. In this scenario, you need to get either the browser or the web server to stop using persistent connections. Of course, this may make it less efficient for serving up normal web pages.

RE: No of concurrent requests per session
Hello: Hello: Can u tell how to prevent browser or webserver using persistent connection ? thanks and regards, -- Kannan. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Monday, February 13, 2006 9:58 PM To: Tomcat Users List Subject: RE: No of concurrent requests per session I suspect the problem relates to pipelining of HTTP 1.1 requests over a single persistent TCP connection. Pipelining is intended to improve efficiency, allowing the need for multiple images to present a web page be expressed to a web server one after another, before any of the responses are given. However, the responses must be presented in the same order as the requests, and therein lies your problem. If your short running request is issued over the same TCP connection as one of the earlier, yet to be responded to, long running requests, the response to the later request must wait for the earlier request to be responded to first. In this scenario, you need to get either the browser or the web server to stop using persistent connections. Of course, this may make it less efficient for serving up normal web pages.

context error
hi, When i add a Context in the server.xml, an error occurs: Apache Tomcat/4.1.31 Catalina.start: LifecycleException: Context startup failed due to previous errors LifecycleException: Context startup failed due to previous errors at org.apache.catalina.core.StandardContext.start(StandardContext.java:3578) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1141) at org.apache.catalina.core.StandardHost.start(StandardHost.java:707) at org.apache.catalina.core.ContainerBase.start(ContainerBase.java:1141) at org.apache.catalina.core.StandardEngine.start(StandardEngine.java:316) at org.apache.catalina.core.StandardService.start(StandardService.java:450) at org.apache.catalina.core.StandardServer.start(StandardServer.java:2143) at org.apache.catalina.startup.Catalina.start(Catalina.java:463) at org.apache.catalina.startup.Catalina.execute(Catalina.java:350) at org.apache.catalina.startup.Catalina.process(Catalina.java:129) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:156) Stopping service Tomcat-Standalone Catalina.stop: LifecycleException: Coyote connector has not been started LifecycleException: Coyote connector has not been started at org.apache.coyote.tomcat4.CoyoteConnector.stop(CoyoteConnector.java:1296) at org.apache.catalina.core.StandardService.stop(StandardService.java:499) at org.apache.catalina.core.StandardServer.stop(StandardServer.java:2178) at org.apache.catalina.startup.Catalina.start(Catalina.java:494) at org.apache.catalina.startup.Catalina.execute(Catalina.java:350) at org.apache.catalina.startup.Catalina.process(Catalina.java:129) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:324) at org.apache.catalina.startup.Bootstrap.main(Bootstrap.java:156) If i remove the added context, tomcat will start. In fact, i rearrange the directories, i don't know if this will impact on the Context. If i put all directories under $CATALINA_HOME, tomcat will work well with the Context. $CATALINA_HOME/bin/ shared/ server/ $CATALINA_BASE/bin/ conf/ webapps/ logs/ work/ Context is as following: Context path=/test docBase=test reloadable=true / Best Regards. jacky
RE: New isapi_redirect.dll has problems
OK, first I'll point out that I'm pretty new to Tomcat myself workers.properties.minimal: Is jk even using this config file? Normally it would use workers.properties unless it was configured otherwise. [Mon Feb 13 07:56:49 2006] [info] jk_ajp_common.c (1248): Error connecting to the Tomcat process. These errors suggest that jk is sending threads to tomcat, but tomcat does not have enough threads to provide a response. You might want to try adjusting the backlog, maxThreads and all the other threads properties for your connector in /conf/server.xml I've noticed that if jk cannot receive any more threads from the web server (worker.ajp13w.cachesize too small) or tomcat cannot respond to all the threads that are sent to it (maxThreads too small), it just doesn't seem to respond correctly, leading either to a host not available error in IE or a blank page in Firefox. I personally feel that it would be better if jk could respond with some kind of 500 error. [Mon Feb 13 17:03:09 2006] [warn] jk_uri_worker_map.c (429): Uri http://www.windwardreports.com/root.htm?source=googleid=540 is invalid. Uri must start with / This is a bit weird. Is your web server doing any URL rewriting? You haven't got any links in your application that might end up looking like this: http://www.somehost.com/http://www.windwardreports.com/root.htm?... or even this: /http://www.windwardreports.com/root.htm?...

Blocking AJP13 (port 8009) access
Hi, I'm trying to block external access to port 8009 (AJP13), as only my local host really needs to be able to talk to it. I'm wondering if there are any internal/mod_jk mechanisms for that, or if iptables is the best option. I have tried iptables, which did block external requests, but it also got me in a situation where I had a few hundred httpd processes in a SYN_SENT state ( netstat | grep 8009 | grep -c SYN_SENT ) and returning 503s instead of 200s: iptables -A INPUT \ -p TCP --dport 8009 \ -m state --state NEW \ -j DROP iptables -A INPUT \ -p UDP --dport 8009 \ -m state --state NEW \ -j DROP iptables -A OUTPUT -o lo -j ACCEPT iptables -A INPUT -i lo -j ACCEPT If anyone has iptables rules that work, I'd appreciate it if you could share them. I'd also be curious to know whether people use some other mechanisms to prevent evil folks from connecting to your port 8009 from the outsite and consuming your available connections.
