Re: Apache2+jk+tomcat5.028+uri utf-8 [NOT] SOLVED
An update on the problem Reading through some other posts I got the suspicion that errno=13 was privilege related. On a hunch turned off SELINUX (http://fedora.redhat.com/docs/selinux-faq-fc3/index.html#id2825232) and everything worked great! The next step is to figure out how to run with it back on, but that got me going again. - Original Message - From: "Chris Brown" <[EMAIL PROTECTED]> To: "Tomcat Users List" Sent: Thursday, July 21, 2005 4:06 PM Subject: Re: Apache2+jk+tomcat5.028+uri utf-8 [NOT] SOLVED Hello, Sorry for not replying to the thread referenced in my subject (See July 1st, 2005), I'm new to the list and didn't have the email to reply to. I am having the same trouble that Paul and Steve encountered. (Error connecting to tomcat from mod_jk). Like Steve I have two similarly configured machines, one works, one doesn't. I can provide configuration files and more detailed logs but the errors I get are similar. Maybe I can peek someone's interest or jog a memory by proviging more detail. I'm running two identically configured Fedora Core 4 boxes. The one that works is running on a Pentium II 450mhz running (FC4 i386), the one that doesn't work is running on a Xeon 2.8ghz (FC4 x86_64). I've compiled mod_jk v1.2.14.1 from source on each box configured everything with simple settings from the tomcat connector HOWTOs. I'm running apache 2.0.54-10. I also tried downloading a precompiled binary (jakarta-tomcat-connectors-jk-1.2.10-linux-sles9-x86_64-prefork.so) but didn't have any better results. I tried pointing the working box's workers.properties file to the other boxes tomcat to confirm tomcat was in fact listening on port 8009. That worked. I turned off my firewall to ensure that wasn't the issue. below is the log from mod_jk. I can provide one with debug message but thought I'd start with the shorter version. Thanks for any help on this matter, I'm stumped.

Bill, thanks for the response.

basic authentication won't accept password (intermittent)
Hello, My client has a password-protected folder (as shown in the snippet from my web.xml below). The problem is that, when accessing a protected resource (/members/jobs/index.html), it sometimes asks for the login several times before returning the requested page. (This is using BASIC authentication, so the browser pops up a dialog in response to the 401.) Occasionally it gives up and shows the 401 Unauthorized error page instead. This problem is reproducible across several browsers on Windows 2000 (IE6, Firefox, Opera, lynx ...). The Authorization header is the same for both successful and unsuccessful requests. Hosting provider's environment: Linux 2.4.24 on i686 Apache 2.0.47 Tomcat 5.5.4 Java: Blackdown-1.4.2-rc1 In server.xml, I've increased maxThreads to 250, although this is not a high-volume site. (Obviously I'm shooting in the dark at this point ;-) My questions are: (1) Where should we look for misconfiguration, whether in my app or in the hosting environment? (2) Is there any other explanation for this behavior? This is my first Tomcat site in production, so hopefully it's a configuration problem. I appreciate any suggestions!

I have an include called this
Inside that include I have another include also with flush set to false -
and I still get a blank page - however if I remove the includes within the

Hi Rob,
Thanx for this - this is great - I may have to use this because I think I
have truly found a bug in Tomcat as this issue is not happening on my
Tomcat
3 server. I did a bit more investigation and I found some interesting
things. This is going to be a long email with code and stuff but whoever
wants to read it please do - because the results are weird.
I created the following simple JSP page
<%@ page language="java"
import="javax.crypto.*,java.sql.*,java.net.*,dbc.DBConnectionManager" %>
<%^M
String query = "select * from patient_info where ref_client = 38
and
pat_lname like '%SM'ITH%';";
DBConnectionManager connMgr;
connMgr = DBConnectionManager.getInstance();
Connection Conn = connMgr.getConnection("podb");
Statement SQLS = Conn.createStatement();
ResultSet rs = SQLS.executeQuery(query);
String col1 = null;
String col2 = null;
while(rs.next()) {
col1 = rs.getString("pat_id");
col2 = rs.getString("pat_fname");
%>
<%=col1%>: <%=col2%>
<%
}
rs.close();
SQLS.close();
connMgr.freeConnection("podb",Conn);
%>
As you can see I did a syntax error in the query and the error comes to
the
screen as expected
javax.servlet.ServletException: ERROR: syntax error at or near "ITH" at
character 74
I said that's weird so I tried to compare my complicated JSP files to what
I
have here to see what is different (if I did something wrong) and I found
this
If I add an include at certain parts of the page - I see the result I was
talking about. For example if I do this:
<%@ page language="java"
import="javax.crypto.*,java.sql.*,java.net.*,dbc.DBConnectionManager" %>
<%^M
String query = "select * from patient_info where ref_client = 38
and
pat_lname like '%SM'ITH%';";
DBConnectionManager connMgr;
connMgr = DBConnectionManager.getInstance();
Connection Conn = connMgr.getConnection("podb");
Statement SQLS = Conn.createStatement();
ResultSet rs = SQLS.executeQuery(query);
String col1 = null;
String col2 = null;
while(rs.next()) {
col1 = rs.getString("pat_id");
col2 = rs.getString("pat_fname");
%>
<%=col1%>: <%=col2%>
<%
}
rs.close();
SQLS.close();
connMgr.freeConnection("podb",Conn);
%>
I get the error page as I should - however If I move the include to below
the <%@ page language="java" - I get a blank page!!
Now here is where it gets weirder - if I force a java syntax error like as
follows (I corrected the query):
<%@ page language="java"
import="javax.crypto.*,java.sql.*,java.net.*,dbc.DBConnectionManager" %>
<%^M
String query = "select * from patient_info where ref_client = 38
and
pat_lname like '%SMITH%';";
DBConnectionManager connMgr;
connMgr = DBConnectionManager.getInstance();
Connection Conn = connMgr.getConnection("podb");
Statement SQLS = Conn.createStatement();
ResultSet rs = SQLS.executeQuery(query);
String col1 = null;
String col2 = null;
if (col1.equals("yes") {
//test
}
while(rs.next()) {
col1 = rs.getString("pat_id");
col2 = rs.getString("pat_fname");
%>
<%=col1%>: <%=col2%>
<%
}
rs.close();
SQLS.close();
connMgr.freeConnection("podb",Conn);
%>
An error will get thrown to the screen

However if I try to force a null pointer error by correcting my syntax
error - I get a blank screen! If remove the include I get the null pointer
error no problem. The other behaviour I noticed as well is that as I said
before if the include is above the <%@ page language piece it works
fine - only if its an html - if its another jsp file - I get a blank
screen
as well.
So has anyone else seen this behaviour - is there a fix or a work around -

RE: jsp stuff
You don't need to change anything in tomcat to make it access a database except one thing - you need is a compliant JDBC driver which you through into the Common Library directory of tomcat. Once tomcat starts it will load the driver and then at that point you can use code to access the Database. I would recommend you use a pooling tool as well - to pool your connections and limit resource use. Check google - lots of info out there.

Re: Request parameter data not being recognised as UTF-8
If you take a look at the API docs for ServletRequest.setCharacterEncoding(), they say
"This method must be called prior to reading request parameters or reading input
using getReader()."
By the time execution gets to your JSP page, something has probably read your
request parameters - maybe an MVC controller servlet of some sort.

Any time I create a new version of one service, I need to replace the previous jar file into WEB-INF/lib, so to make changes effective I also must reload the axis context (using manager facility). My problem is that in production environment we have 6 machines with a shared filesystem (gpfs) in load-balancing. So I think that if I do a reload of the context using manager, I actually reload just one of the 6 istances of Tomcat (the one answered me in that moment), but the other 5 don't see the changes made to WEB-INF/lib and continue to run and old version of the service. Take into account that I don't have access to each single machine of the cluster, so I can't do a reload of all the 6 contexts from my machine. There's a way to propagate a context reload between the clusters?? I really need to access each machine and reload for each single Tomcat instance? Thanks in advance.

Re: Replacing a class file
That sounds like it should work to me. I do the same thing every day. Perhaps this code has also been compiled into a jar and is sitting in WEB-INF/lib or tomcat/shared. Or try deleting the files in the tomcat/work directory. I think technically this shouldn't fix it, but it doesn't hurt if you're desperate. And of course check all the obvious things like: Are you sure you are copying the new class file? Are you sure you saved the java file when you compiled it? Are you sure you are putting it in the right directory? Perhaps you have more than one web app/web site on your server. If you have more that one instance of Tomcat running maybe you restarted the wrong one. Check file permissions. Maybe the new class is actually running and the changes you made to the java file don't actually fix the problem.

Re: Request parameter data not being recognised as UTF-8
Thanks Mark.
I entered "Tübingen" and I got back "Data posted to this form was:
Tübingen". localhost_log also has "Tübingen"
It does this for both port 8080 (Tomcat directly), and port 80 (through
Apache).
I checked the Tomcat 4.1.31 release notes
(http://apache.sunsite.ualberta.ca/jakarta/tomcat-4/v4.1.31/RELEASE-NOTES)
and the closest thing I could find is the following, which is only
documentation.
[4.1.31] Docs:
Correctly document default value for useBodyEncodingForURI
I modified the simple jsp page to have these lines:
<%
out.print("Char endoding = " + request.getCharacterEncoding() + "");
request.setCharacterEncoding("utf-8");
out.print("Data posted to this form was: " + request.getParameter("mydata") +
"");
out.print("Char endoding = " + request.getCharacterEncoding() + "");
%>
The response was:
Char endoding = null
Data posted to this form was: Tübingen
Char endoding = utf-8
Should I have something in my web.xml file? Is there some way to verify
that what I enter in the Connector tag in server.xml is actually
sticking? I couldn't find any errors in localhost.log nor in
cataline.out (well, no relavent errors at least).
Thanks a lot, to anyone who has any ideas.

Re: Jsp and xml
Two things I can think of: 1. Remember that a line that contains <% ...code... %> will also produce an end-of-line (eol) character, so instead of something like this: <% for (int i=0; i <% } %> do something like this: <% for (int i=0; i <% } %> or this: <% for (int i=0; i <% } %> 2. Maybe you are producing the xml/jsp on a Windows computer that produces CR + LF characters and viewing it on a computer that interprets these as two separate EOL characters. This is not as likely as number 1 above. Tim Koop Kiran Patel wrote: Hello all, I am creating a xml document using JSP. The JAVA codes in JSP creates blank lines in xml document.

Problem Bringing up Admin
I've installed tomcat 5.5.9 and downloaded the admin package.

getServletContext() returns "/" for default context defined outside of server.xml
Hi, I'm trying to setup the default Context for a Host, without defining it in server.xml. In conf/Catalina/localhost I've created a file named .xml, and defined the Context within it, without defining the path - I understand from the Tomcat docs that it should be inferred as "". This is all working fine, apart from one issue: a call to HttpServletRequest.getServletContext() returns "/" rather than "" - the servlet API says "" is correct . If the default context is defined in server.xml, getServletContext() returns "" as it should. I'm guessing that this might be a bug, but I'm reluctant to say so because I suspect I might be doing something wrong - the Tomcat docs do say "it is not recommended to place elements directly in the server.xml file", but then creating a .xml file seems a little odd to me... Is that really the right way to do it? I've tested this on Tomcat 5.5.4 and 5.5.7. Cheers Martin - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: Max thread/session timeouts
Hi Michael,
Thanks for the information.
I will try to further study this problem and let you know if I found
anything useful.
Mean while can you let me know about any JVM options that you are
using for running your tomcat and that you think will be useful in
server performance and scalability. So that I can check whether any
one of them are applicable in our context.

My experience was that with a single Tomcat on a large machine, you'll
never use that box fully. Besides that you can't get the Sun JVM to
accept a large amount of threads while giving them enough memory, Tomcat
seems to have performance problems with 3000+ threads busy at the same
time. The BEA JVM (JRockit) performs better in terms of memory and
threads but is slower than the Sun JVM. If you have rather complex
database operations performed by your webapp, this will get you into
trouble, because if there is a single bottleneck in the whole system,
the requests will pile up in the server, it hits its thread limit, and
ceases operation.
So, I have made good experiences with 4 Tomcats on a 2xXeon with 4GB.
The server's load is somewhere between 70% and 100% while running with
high load and can handle more concurrent requests than a single Tomcat.

We use 2003 Standard Edition and get the following limitations:
. Windows only provides 2GB memory to all applications running,
regardless of how much memory you have. All other memory is used for
Windows itself. With a registry key, you can extend this to 3GB. I
don't have the key handy, but it can be found in MSDN.
. The somewhat larger problem is the crappy TCP stack on Windows. A
single Tomcat easily handles 1000 concurrent connections, but if I start
4 Tomcats, I get a WSAENOBUFS error ("An operation on a socket could not
be performed because the system lacked sufficient buffer space or
because a queue was full") at about 3300 concurrent connections.
Because each Tomcat runs with his own instance of the JVM, I suppose
the problem is Windows, the network or anything else that is used by all
Tomcats at the same time. Even worse, after such a crash, there is a
10% chance, the Tomcats not resuming normal operation but crashes
completely.
. Windows has a default limit of 5000 ephemeral ports that can be used
fo outgoing connections. This can be changed with the MaxUserPorts
registry key. Also, the TcpTimedWaitDelay key is relevant for network
performance. Both are described here:
http://msdn.microsoft.com/library/en-us/randz/protocol/tcp_time-wait_delay.asp
I'm now really irritated by this problem. I need a capacity of about
15000 concurrent connections for my project. I also have 3 2xXeon
servers here, but windows (or anything else) doesn't allow more than
~8000 connections until it dies.

Reloading web context in a cluster
Hi, I'm developing some web services using Axis. The whole axis context (containing all my services) is embedded as a servlet into Tomcat 5.5.9. Any time I create a new version of one service, I need to replace the previous jar file into WEB-INF/lib, so to make changes effective I also must reload the axis context (using manager facility). My problem is that in production environment we have 6 machines with a shared filesystem (gpfs) in load-balancing. So I think that if I do a reload of the context using manager, I actually reload just one of the 6 istances of Tomcat (the one answered me in that moment), but the other 5 don't see the changes made to WEB-INF/lib and continue to run and old version of the service. Take into account that I don't have access to each single machine of the cluster, so I can't do a reload of all the 6 contexts from my machine. There's a way to propagate a context reload between the clusters?? I really need to access each machine and reload for each single Tomcat instance? Thanks in advance.

Here is the servlet i place in TC1 which open a SSL connection to TC2.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.net.URL;
import java.net.URLConnection;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException {
PrintWriter out = response.getWriter();
out.println("Hello World");
URL url = new URL("https://154.123.23.10:8443";);
URLConnection con = url.openConnection();
con.connect();
}
}
I have used java keytool to generate a self-signed cert and also a keystore
in TC2. Below is the Connector element of the server.xml of TC2
I also imported the self-signed cert into the truststore of machine which
host the TC1. The place i store the self-signed cert of TC2 is
jre_home\lib\security\cacerts
I think i have setup the SSL correctly.
Does anyone know how to resolve the exception "java.net.SocketException:
Default SSL context init failed: null" I mentioned above?
Thanks for your help

Re: What commands to run in the Tomcat Debug Mode on Linux
Wendy Smoak wrote: I'm also unsure of the difference between 'run' and 'start'. If you just type 'catalina.bat' with no parameters, it prints out a usage statement that lists 'jpda start' but not 'run jpda'. Since it lists both 'run -security' and 'start -security' separately I have to wonder if 'run jpda' is even a valid option. "run jpda" does not work. But "jpda run" works fine , I use it all the time. Christoph - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
