servlet/jps: servlet is Ok but jsp NoClassDefFoundError
I am working with Tomcat 5.0 In a working webapp \ondemand (with only jsp) I added a servlet. The servlet work correctly but the jsp is not able to find the lib/engine.jar (where the its classes are defined). Without Servlet the JSP works. With servlet I can not have my index.jsp I tried to put the jar related to servlet in common/lib, but is the same, the servlet works, but not the jsp. Any idea? Thanks. Regards.

Tomcat Clustering - Replicated Sessions
According to the Tomcat (5.5.9) documentation after a sessions has reached a certian period of inactivity it expires. However my question is when is this expired session marked by the JVM for garbage collection. The reason I ask is that our application has an interesting problem. If we start up a single server (configured for a cluster) and have the application run memory looks good, CPU is good, response time is good. However when we start up the 2nd clustered instance after a day or two both servers start showing up with OutOfMemory errors. The only new item introduced is that we are now replicating sessions between the applications. We changed the replication mode to asynchronous after having performance problems using pooled.

Sending custom Date header from servlet?
I'm trying to write a servlet that sends Date and Expires headers that are a few days in the past. (It's the server side of a caching test case.) Adding the old Expires header is trivial: response.setDateHeader(Expires, System.currentTimeMillis() - 3 * ONE_DAY); but if I put in the identical code with Date instead of Expires, nothing seems to happen. I still get a Date header that's set to the actual request time. I've poked around a little bit in the Catalina code, and I can't figure out why this would be happening. There's code in HttpProcessor that adds a Date header right before calling connector.getContainer().invoke(), but since my servlet code runs after that, I think it should override this default value. Does anyone have advice on this, or see anything I'm missing? Thanks! Laura Werner BeVocal, Inc. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I made sure all the following were done:
1) Classpath is set

n/lib/servlet.jar:.
export CATALINA_HOME
export JAVA_HOME
export PATH
export CLASSPATH
2) Put the servlet in
/usr/java/usr/java/jakarta-tomcat-4.0.4/webapps/begjsp-ch01/WEB-INF/classes/
ExampleServlet.java
Compiled it from there. Shutdown restarted Tomcat.
I went to http://localhost:8080/begjsp-ch01/servlet/ExampleServlet get 404

Does anyone have any suggestions?
Thanks.

Re: Tomcat PID: alive or not
Which monitoring programs do you advise me? Laura Alle 17:53, martedì 18 giugno 2002, hai scritto: Having the PID doesn't tell you anything about whether or not the process is capable of serving requests. For that, you will have to create a script and run it in a cron job that makes a request to tomcat every so often (every minute?) and checks to see if a valid response was received. If not, restart tomcat using the PID. There are any number of monitoring programs out there, UN*X-based or Windows, that, given a URL, can determine if a valid response was received. I usually create a small servlet that does nothing but output a string that says I'm OK or something similar. Then the monitoring script looks for that text string in the reply, and behaves accordingly.

Hi Laura,
Tomcat actually does have a pid. It is a java application. Under
Solaris if you do a ps -elf |grep nativ you will see a listing
beginning with your JAVA_HOME and ending with ../bin/sparc/nativ_t.
That's the pid of the java virtual machine. If you have multiple java
apps running each will have a JVM so you may need to sort out which
java pid is Tomcat.
You can also use top after starting Tomcat. You will see an entry for
java in the table along with the pid and memory and cpu usage info.

I have this working on HPUX, if you are trying this on another UNIX - I'm not sure what may happen but here are some hints to track things down. 1) Make sure the directory you are starting tomcat you are typing bin/startup.sh. This ensures you will write the the correct log directory. 2) My original version of the script was: #!/bin/sh echo $PPID logs/tomcat.pid This printed out the wrong PID since the first line created an extra shell process for the script to execute in. I wonder if Runtime.getRuntime().exec is creating an extra process which would cause you to get the wrong pid. If that is the case - I can't be of help.

Just for clarification, doing tomcat.pid wouldn't really work, because
all you would get is the ps entry for that value. You'd have to use cut

from ps -ef | grep java | grep myapp and redirect it to tomcat.pid.

Security - Attack
Hi all, well I have, in my opinion, a very interesting question. Last week we went in a production enviroment: we have apache + tomcat with an important web application xxx (http.conf has JkMount /xxx worker). Well, this morning I have discovered that somebody has tried to attack my server: in the Apache error log I have found calls as /scripts/..%5c%5c../winnt/system32/cmd.exe, /scripts/., and so on. My question is: is Tomcat secure? How can I do Tomcat secure? Is all my system secure? ( my machine is a solaris 8). Thanks Laura
Other question
Hi all, thanks for your reply (Security - Attack): you are telling me that I shouldn't worry because Apache is secure. (I hope it) I have one other question: If Tomcat shouts down for some cause, how can I know it? For example, Apache has a PID and so you can control if the apache process, with that PID, is alive. But Tomcat doesn't write any PID: how can I know if Tomcat is alive or not? Is there any script for that? Thanks for your help Laura

Tomcat memory problem ?
Hi all, my system is this: I have a solaris machine (2GB RAM) with apache 1.3.19 and two instances of Tomcat 4.0.3 in a load balancer configuration. I started all three days ago: this morning I have found the two Tomcat dead. All my servlets didn't respond and all the system was dead. It's terrible. Did someone ever have this problem? Often I read in the mail list that there is some problem in memory in Tomcat: is it true? Does someone know something?

It is an sendRedirect on their server, then you're in trouble, because then you would have to add some demarcation information onto the request to identify the server.

SOLVED [PLEASE HELP ME: JNDI ERROR 1]
Hi all, I solved my problem with Oracle 8.1.6 and JNDI. I remember you the problem was that when I tried to execute Connection con = ds.getConnection() (where ds is a DataSource token by JNDI) I receved: Network Adapter could not establish the connection. Well first a couple of considerations: 1) I discovered that this problem is not specific of Oracle 8.1.6 but it can occure with Oracle 8.1.7. 2) The version of driver (classes12.zip) is important but with the correct version of driver the error persist. At least the solution. In the server.xml where you set your JNDI connection, the value of DriverName isn't jdbc:oracle:thin:@HOST:PORT:SID but the correct string is: jdbc:oracle:thin:@(description=(address=(host=HOST)(protocol=tcp)(port=PORT))(connect_data=(sid=SID)(SERVER=DEDICATED))) whre the part SERVER=DEDICATED is very very very important.

Re: PLEASE HELP ME: JNDI ERROR 1
I think that the context is ok bacause the log file (catalina.out) tells me:
[DEBUG] InitialContext = javax.naming.InitialContext@46110f9b
[DEBUG] lookup java:comp/env = org.apache.naming.NamingContext@3700f9b
[DEBUG] Datasource = Resource reference to a factory for java.sql.Connection
instances that may be used for talking to a particular
database that is configured in the server.xml file.
So ds isn't empty: the exception is thrown when I call:
Connection con = ds.getConnection();
The Datasource is Tomcat's Datasource ( I have followed jndi tutorial)
Laura
Alle 18:54, lunedì 15 aprile 2002, hai scritto:
Put a break point in between and examine Context and its contents. Also
check the spelling/case of datasource lookup name. If you are creating
the Datasource yourself, check for any exceptions during its registration.

upgrade
Hi all, I have a question regarding how to upgrade tomcat. I think this problem is common to everyone because tomcat is a servlet engine which is in constant evolution. So for example I have apache + tomcat 4.0.2 with my web applications under /webapps: how can I upgrade to tomcat 4.0.3, which solves some bugs, without reinstalling all ( and configure workers.properties, servlet.xml, web.xml, ) ? I think this is an important point because people can be discourage using tomcat if it's difficult to upgrade.

I have followed your advice and it seems ok! Tomcat is started (with apache ).
In my configuration I have apache + two tomcat (4.0.3) with load balacing (I

Is it normal?
Must I configure something?

Alle 14:17, venerdì 29 marzo 2002, hai scritto:
I have two cosiderations about your Tomcat-nodody advices:
1) There is no tomcat4.conf in conf directory.
2) Your advice is to do
- chown nobody:nobody /usr/local/tomcat1
- su -l -c /usr/local/tomcat1/bin/startup.sh
There is a big problem with this procedure, in my opinion: the problem
is a security problem. We know that Apache runs as nobody, but the
directories are root:root. The father process forks child processes
which are nobody, so if someone tries to execute a cgi, this has no
privilegy. But if you execute chown nobody:nobody /usr/local/tomcat1,
all directories are nobody, so anyone can write e do everything.
I'd like starting tomcat as apache, with the same security policy.
First of all, you need to know what you'll be protecting and from whom. I'd
suggest user tomcat and group tomcat. The vital directories should be
owned by root:tomcat. The files should be accessable to tomcat user
(which should be in group tomcat).
chown -R root:tomcat $CATALINA_HOME
find $CATALINA_HOME -type f -exec chmod 640 {} \;
find $CATALINA_HOME -type d -exec chmod 750 {} \;
chmod 750 $CATALINA_HOME/bin/*.sh
This way, only members of tomcat group can access those files. They
should not be world readable, especially ./conf/, since you could be
storing sensitive data there (database connection parameters, passwords,
etc.). After this, you should be able to run Tomcat under user tomcat.
One word of caution: only root can open ports below TCP:1024. So, setting
up a HTPP connector on port 80 will fail. 8080 and WARP should be fine.
This idea can be developed further, with virtual hosts placed in separate
user accounts, both for Apache and Tomcat. The question of access will
arise, of course. Owners of virtual hosts shouldn't be in tomcat group. A
directory where they would deploy their web applications should be
accessable by Tomcat, but they should be able to upload content to it as
well.
Nix.

Re: catalina.policy: file:?
Hello Roshan,
first of all thank you very much for your engagement.
If you could post your policy file and a decent chunk of your log output,
it might help :-)
My policy file is the standard-file from the distribution with just two changes:
// These Permissions are in the default-grant-section
permission java.net.SocketPermission localhost:3306, connect,resolve;
permission java.net.SocketPermission 127.0.0.1:3306, connect,resolve;
...and below:
grant codeBase file:${doc.root}/- {
permission java.io.FilePermission ${doc.root}/-, read, write, delete;
};
(as mentioned before)
The decent chunk of my logfile I have attached as catalina.out.txt.
When you take a look at this file it seems, that the webapp doesn't see my second
grand-entry :-(((
Thanks for any help!
Laura

Re: catalina.policy: file:?
Hello Roshan,
So the grant in the snippet below uses a file URL to give classes from
the ${work.dir} read access to all files under ${doc.root} directory and
read, write, delete access to files under ${work.dir} directory. The -
following the / refers to all files in a directory and all its
subdirectories
I think I understand that. But why doesn't this work for me:
---snip---
grant codeBase file:${doc.root}/- {
permission java.io.FilePermission ${doc.root}/-, read, write,
delete;
};
/---snip---
Shouldn't this grand _any_ file (Servlet, JSP-File) in the filesystem
under ${doc.root} the rights to read, write und delete _any_ file in
the filesystem under ${doc.root}???
What I get is:
java.security.AccessControlException: access denied
(java.io.FilePermission
C:\Programme\ApacheGroup\jakarta-tomcat-4.0.1\webapps\jspMyAdmin\logs\parse_time_log
write)
Helpless...

Give webapps FilePermissions in catalina.policy
Hello list,
I'm using Tomcat4.0.1 with the -security-option.
Now I want every webapp to have the read- and write--FilePermission to
the files in it's own Doc-Root.
I tried the following in catalina.policy:
---snip---
// These permissions are granted by default to all web applications
// In addition, a web application will be given a read FilePermission
// and JndiPermission for all files and directories in its document
// root.
grant {
[...]
// Set FilePermission for Files in own doc-root
permission java.io.FilePermission ${doc.root}/-, read, write;
};
/---snip---
Unfortunately it doesn't seem to work.
For example with jspMyAdmin
(http://sourceforge.net/projects/jspmyadmin) I get the following error:
---snip---
java.security.AccessControlException: access denied
(java.io.FilePermission
C:\Programme\ApacheGroup\jakarta-tomcat-4.0.1\webapps\jspMyAdmin\logs\parse_time_log
write)
The exception class was : class java.security.AccessControlException
/---snip---
The Security-Manager won't let the webapp write the Logfile.
Anyone with an idea for me? RTFM wellcome!
Ciao
Laura

Re: Give webapps FilePermissions in catalina.policy
Hello Frank, hello list,
I believe the syntax is a bit different for web apps
as indicated by the example in the file. Here is
my spec for AllPermission for myApp. You should be able
to modify it for your purposes:
grant codeBase file:${catalina.home}/webapps/myApp/- {
permission java.security.AllPermission;
};
thank you very much for the code!
When I modify my catalina.policy to:
---snip---
grant codeBase file:${catalina.home}/webapps/jspMyAdmin/- {
permission java.security.AllPermission;
};
/---snip---
...the application works. But giving AllPermission certainly isn't what
I want. So I tried this:
---snip---
grant codeBase file:${catalina.home}/webapps/jspMyAdmin/- {
permission java.io.FilePermission
file:${catalina.home}/webapps/jspMyAdmin/-, read, write, delete;
};
/---snip---
Here I get the error again:
---snip---
java.security.AccessControlException: access denied
(java.io.FilePermission
C:\Programme\ApacheGroup\jakarta-tomcat-4.0.1\webapps\jspMyAdmin\logs\parse_time_log
write)
---snip---
Is there any other Permission I have to set to make my applications make
writing files?
Besides with this approach I have to make an entry for every application.
Isn't there a way to say:
Give any webapp the FilePermissions read, write und delete for the files
in the specific doc-root.?
Thanx again
Laura

tomcat problems with double-byte form data?
Hi. I'm having problems when I try to submit double-byte form elements using "method=post" and using Tomcat 3.2.1 and Win NT 4.0. In earlier versions of our product, we used Jrun as the servlet engine. With Jrun, we ended up having to use the Javascript "escape()" function to encode the double-byte form elements. Once we did that, everything worked fine. If we try to use the Javascript "escape()" function with Tomcat, we get a java.lang.IllegalArgumentException: Decode Error at org.apache.tomcat.util.RequestUtil.unUrlDecode(RequestUtil.java: 353). If we don't use the escape function, the double-byte stuff ends up as the ever-popular ??? garbage. I found a patch for Tomcat 3.2.1 that was supposed to fix a some kind of bug for multi-byte characters, but it didn't help. Any ideas? -- Laura E.

Re: ROOT-Servlets not found
I found the following message in the mail archive, but with no reply. As I have exactly the same problem, I would very much like to know what the answer is. Thanks Laura Foster Hello, this is the problem I have: I'm using Tomcat with Apache. All my static-files I put into the path TOMCAT_HOME\webapps\ROOT. The Servlets into this web-inf\classes. The static files should be served by apache. Into the httpd.conf I wrote: ... DocumentRoot "C:/programme/apachgroup/jakarta-tomcat/weapps/ROOT" ... Include ...\mytomcat-apache.conf the mytomcat-apache.conf: ... Location /WEB-INF/ AllowOverride None deny from all /Location LocationMatch /*.jsp SetHandler jserv-servlet /LocationMatch ApJServMount /servlets /ROOT the servlet.xml: ... Context path="" docBase="webapps/ROOT" debug="0" reloadable="true" /Context ... When I'm trying to invoke Servlets in the example-webapp everything works fine. Also the serving of the static-files are working properly, but the servlets I want to open by eg. http://localhost/servlets/IsItWorking a 404-error is coming up. What am I doing wrong?
