Installing in Redhat 7.0
I seem to have successfully installed tomcat and cocoon in a Redhat 7.0 system. I used Henri Gomez' rpms. One comment on the contents of /etc/httpd/conf/workers.properties file. It contained # # The JVM that we are about to use # # This is for Java2 # worker.inprocess.jvm_lib=$(workers.java_home)$(ps)jre$(ps)bin$(ps)classic$(ps)jvm.dll Is this value used? I replaced the .dll with libjvm.so One other comment. After installing cocoon 1.8.1, I was trying to access Cocoon.xml as localhost/Cocoon.xml. This did not work, but localhost/cocoon/Cocoon.xml did. I seem to recall the localhost/Cocoon.xml worked when using mod_jserv. Peter -- Peter B.

Is the server.xml using server.dtd?
Hi, I'm (still) using TOMCAT Version 3.1. I'd like to change the port for my servlets and JSP-pages from 8080 to 80. Now, I assume you have to change these settings in the file "server.xml". I have two questions regarding this file: 1. Why isn't the "server.dtd" used in the "server.xml"? The structure in the DTD-file is different from the one in the XML-file. The DTD-structure corresponds to the one in the book I'm using "Core Servlets and JavaServer Pages" (Marty Hall), the XML-file doesn't! 2. How can I be sure the default port number for my servlets is 80? I'm using the PWS 4.0 and the "isapi_redirect.dll".

Solaris 8, apache and mod_jk - problem
Hi, I'm trying to configure apache 1.3.9 and tomcat 3.2 with mod_jk under Solaris 8. I'm using the example contexts supplied with the tomcat. A standalone configuration of tomcat serves the contexts OK as does tomcat with apache using mod_jserv. However, I can't get jsps to run using mod_jk - when I try to run one I just get the source code. Servlets are also problematic: for the provided webapps/examples context, the servlets run OK if I do not explicitly specify that context in the server.xml file. If I specify it, tomcat complains that it can't find the file (and yes, I have the location right). I suspect that the workers.properties file is the problem seeing as I'm following the off-the-shelf configurations for tomcat. However, the provided workers.properties file refers to DLLs, indicating a win32 setup. I've set the paths required as per my system but I may be missing something - the output from the mod_jk logs seems to indicate that mod_jk can't find a worker for jsps. I've tried both ajp12 and ajp13. The configuration files I'm using are attached. Any help would be greatly appreciated.

RE: SSL Help
browse the archive those recent days/weeks the secret are: it is advised to use apache with openssl (mod_ssl or apache+ssl) as the SSL processor and just configure it to delegate servlet and JSP to tomcat... look at http://www.modssl.org/ or http://www.apache-ssl.org/ for explanations, install doc, binaries, advices... anyway you can make tomcat able to serve SSL directly. install JSSE from SUN as documented (detail in some of my former messages here) this include putting the.jar in a lib or lib/ext directory as explaine, and twickle some security.properties create private key in the java keystore, produce a certificate (externaly or auto-certifies) with CN=the.dns.name.of.my.tomcat and add the certificate to the java keystore... modify the server.xml as explained in come comments... (I've send here a working server.xml) add some options in TOMCAT_OPTS (in tomcat.bat) so that URL Factory supports SSL, and JSSE can find the truststore... set TOMCAT_OPTS=%TOMCAT_OPTS% -Djavax.net.ssl.trustStore="%TOMCAT_HOME%/../openssl/maui/cacerts" -Djava.protocol.handler.pkgs=com.sun.net.ssl.internal.www.protocol may the force be with you. you can do it! this can work, I've tested ! -Message d'origine- De: venkatesan [mailto:[EMAIL PROTECTED]] Date: lundi 5 fvrier 2001 12:50 : [EMAIL PROTECTED] Objet: SSL Help Hi All, I am developing web applications using servlets, Rmi, Sql-server and Tomcat in Apache web server under Linux platform.

Newbie Question
I just installed Tomcat 3.2 on Apache 1.3.14. Installed like a charm, all I had to do was restart both services and Apcahe was feeding up the static stuff and Tomcat the JSP/JavaServlets. For the last few days I've been thrying to comprehend the "User's Guide"... Maybe its just me... where can I find some detailed documentation on how to configure tomcat (I'm talking documentaion for dumb asses). Another thing. I've noticed that there is a http://localhost/admin and it supposedly gives you the ability to view/delete/create contexts. It prompts me for a uid/pw when I try to use it... In the server.xml file is says (in lamans terms) that if you want to use it 'don't forget to set a password' it doesn't tell me how to set a password.

Re: SERVLET TIMEOUT
Michael: I have a database connection pool servlet which loads on startup. It works fine, but if I don't give it a workout on my test site often enough, it disappears. I suspect Tomcat destroys idle servlets after a certain time has elapsed, but I can't find documentation on this. I don't know if I need to do something with the Tomcat configuration, of modify my servlet so it will be left alone. There is no doubt that the servlet loads on startup, and remains active for a while. Thanks much for the response. -- David Michael Wentzel wrote: My servlet won't stay loaded.

Back to the orginal problem or the performance Other people have reported similar problems under "high" load. No one have ever really given a definition of what high is since it depends upon your application, however I would think that 20 concurent users should be completely supported by Tomcat (our application does it). Two things to note: 1. People who have reported these issuses usually say that if the requests stop, Tomcat will eventually catch up 2. You might want to check whether or not its your application. Try the same test, but request a small static file. This will show you what the best performance you could hope to get. There were a few messages about a week or two ago about tuning Tomcat, you might want to look at that, although there wasn't much there. Another thing is you might look throught the source and see where they initalize the thread pool (probably in PoolTcpConnectors). Uping this size should give you more concurrent users, however it will add more overhead when the server is idle. While you're running your test, keep an eye on your network bandwidth usage and cpu utilization. Its possible that you might be saturating the network (are the responses very large?) or that you are only using one of your 4 processors (I have no idea how to fix this). Randy PS Bob

Hello, I have configured with OpenSSL (to Tomcat directly), made a key, etc. Now I can have a secure connections to my server, but browsers complains that my certificate isn't good, not signed, not knows, etc. Seems that browsers have to problems with Verisign or RSA (?) certificates, which cost 600-1000 dollars per each one. I'm don't have those kind of money to spend. So, how do I get my certificate, so the browser wouldn't ask to install it, or approval from the user. Thank you, John.

how to USE differnet contexts
I have set up two contexts. One runs from webapps/ROOT, the other from webapps/test. The contexts appear to be set up correctly. My application runs fine from webapps/ROOT. The problem is running from webapps/test. The main servlet calls JSP pages, which redirect to the main servlet again. The JSP pages just reference /myServlet. They do not specify a context, such as test/mysServlet, or ROOT/myServlet. I don't want to have to change every JSP page to run this application in a different context. What do I need to do this, so context is independent?

Off topic - HTTP POST example?
Not exactly a Tomcat issue, but it's in the web world of Java servlets: Does anybody have any code samples that would demonstrate an HTTP POST (I'll use JSSE and really do an HTTPS POST, but I suspect the code will be the same or very similar)? I've seen URL class code that does a GET, but nothing that shows how to setup the HTTP body parts and encoding that go on in a POST.

Re: Off topic - HTTP POST example?
Well, do you mean POST from web-form? Then it would be:
form name="posttest" action="http://server/servlet/ServletName"
method="POST"
Name: input type="text" name="name"
input type="submit"
/form
If you asking how to handle POST's from a servlet, it would be:
import javax.servlet.*;
import javax.servlet.http.*;
public class ServletName extends HttpServet {
public void doPost(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = res.getWriter();
String name = request.getParameter("name");
out.println("The parameter name = " + name);
}
/* Also you can redirect POST-GET methods by doing this: */
public void doGet(HttpServletRequest request, HttpServeltResponse
response) {
doPost(request, response);
}
}
That's about it. To secure it, just put this stuff under secure section
of your site.
Or request it thru secure https protocol.
Good luck,
John.

A JSP/Jasper question
Title: A JSP/Jasper question The servlet spec defines that request.getParameter() returns null if the parameter wasn't passed to the page. However, it would appear that Jasper chokes on this case. Since JSPs are an extension to servlets shouldn't the behavior be the same? If I hacked the URL to pass in all the parameters for the page when the page is compiled, will I get this error with future acceses when, theoretically, Jasper isn't involved anymore? -Sean Hammon org.apache.jasper.compiler.ParseException: /part2/doc_root/vp/quote.jsp(13,51) Attribute firstname has no value at org.apache.jasper.compiler.JspReader.parseAttributeValue(JspReader.java:499) at org.apache.jasper.compiler.JspReader.parseTagAttributes(JspReader.java:615) at org.apache.jasper.compiler.Parser$Directive.accept(Parser.java:192) at org.apache.jasper.compiler.Parser.parse(Parser.java:1077) at org.apache.jasper.compiler.Parser.parse(Parser.java:1042) at org.apache.jasper.compiler.Parser.parse(Parser.java:1038) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:182) at org.apache.jasper.servlet.JspServlet.doLoadJSP(JspServlet.java:462)
RE: A JSP/Jasper question
This error message is about a badly formatted JSP page at line 13, column 51 (or is it line 51, column 13 - I never can remember). Apparently Jasper doesn't like your variable firstname. Without seeing your code its difficult to guess the cause of this, but its probably because you haven't declared you want to use a bean using jsp:useBean before you have called jsp:setProperty. Again, this is just a guess from the exception you included. This is in no way a runtime error, but a parse and compile time error, therefore it is impossible to infer whether or not Tomcat is correctly handling request.getParameter(), however from my own experience, it follows the servlet spec.

Re: Questions
Easy. Edit 2 files. First under %TOMCAT_HOME%/conf/server.xml In ContextManager (you'll see similar stuff) put this: Context path="/path_after_domain" docBase="/www/world" crossContext="false" debug = "0" !-- 0 to 9 -- reloadable = "true" /Context So, now assuming you have /www/world directory. You can make up shell script, to do the job next time like this one I have, and execute it in /www/world directory. #!/bin/sh # Must be executed in main directory of # docBase parameter of servlet.xml. mkdir WEB-INF; mkdir WEB-INF/classes; mkdir META-INF; ln -s WEB-INF/classes servlets; cp %TOMCAT_HOME%/webapps/ROOT/META-INF/MANIFEST.MF META-INF/ cp %TOMCAT_HOME%/webapps/ROOT/WEB-INF/web.xml WEB-INF/web.xml Or do that by hand... good luck.

Rules regarding opening files in JSP pages served by Tomcat
Hello,
I have a JSP based application for which the JSP files reside in directory
C:\tomcat\jakarta-tomcat\webapps\myapp.
One of the JSP files is trying to open a config file configs.xml which also
is present that directory. The JSP code is using
request.getRealPath("configs.xml") which returns
C:\tomcat\jakarta-tomcat\webapps\myapp\configs.xml to resolve the actual
location of the configs file. Yet when the code tries to open this file it
says that C:\tomcat\jakarta-tomcat\webapps\myapp\configs.xml is not found.
But IT IS there. So why can't it see the file? Are there rules which
prohibit accessing a file in this directory. How do I grant access to this
directory?
I am able to load the file if I place it in C:\tomcat\jakarta-tomcat\bin
and skip the use of the request.getRealPath call. But that is not a nice
solution. I would like the config file to reside with the JSP files it
relates to. How can I accomplish this?
Thanks,
Keith

JDBCRealm authentication with interbase interclient
This may be more of a developer question, but the guidelines seem to discourage non-developers from posting to the developer list, so I apologize if this is the wrong place. I don't know if any of you out there are using interbase with Tomcat 3.2.1, but I'm attempting to do so. I'm curious about the behavior when a user first enters a secured realm. Using the exact same setup as I've used successfully using the jdbc-odbc bridge and mysql, i'm trying to authenticate a user. I can do so fine if I force my way into login.jsp. However, if I just try to connect to a secured area, tomcat throws a NullPointerException, which appears to have bubbled up from the jdbc driver. Apparently, when a user first enters a secured realm tomcat calls authenticate(null, null) or something. The interbase JDBC driver appears NOT to like this behavior. However, it would seem to me that the proper behavior in the case of a null username would be to return false immediately, rather than run a query off the database with a null parameter. The code I'm referring to is circa line 306 in apache/tomcat/request/JDBCRealm.java Any thoughts? --erik - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

While there are connection pools (I have not used them but others on the list can point you to them), I find the easiest solution is a session variable. Then make a function you can call with the session and db connection info. The function checks the session for the DB varaible. If it's not there it creates the connection and adds it to the session. Then returns the DB. That way the call to get the connection looks nice and clean (no nasty if statements to cloud up your HTML on the JSP).

Re: Speeding up database accesses
Sure it possible. For the page for example, at least you can do is
use
---
%@ page import="java.sql.*" %
%!
Connection conn;
PreparedStatement stmt;
%
%!
public void jspInit() {
try {
String url = "jdbc:as400://URLHERE";
String id = "id";
String pass = "pass";
/* Making a sql string */
String sql = "SELECT xxx FROM yyy WHERE xxx = '?'";
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
conn = DriverManager.getConnection(url, id, pass);
stmt = conn.prepareStatement(sql);
} catch(SQLException e) {
e.printStackTrace();
} catch(ClassNotFoundException e) {
e.printStackTrace();
}
}
%
%!
/* To close all connections when JSP is destroyed (reloaded, etc) */
public void jspDestroy() {
try {
stmt.close();
conn.close();
} catch(SQLException e) {
e.printStackTrace();
}
}
%
-
Then you can use something like (not tested of course)
-
String email = request.getParameter("email");
stmt.setString(1, email);
ResultSet rset = stmt.executeQuery();
-
But this is for some easy pages. If you want to driver "Yahoo" on it,
it wouldn't help... I will suggest you to take a look at PoolMan JDBC
connection pool. It works nicely here...

AW: Speeding up database accesses
Doing this way you have a large amount of open connection. They stay opened until timeout because you don't know, when the user closes his browser. So I think it's better having a connection-pool managing the DB-connection. You could implement that using a singleton-pattern.

RE: No path info for include page
I think tomcat's getPathInfo is a little wierd. The behavior when you have bound a servlet to a url is to move what you would expect to be in getPathInfo() into getServletPath() . Included pages might be getting handled the same as "mapped" ones, in which case you could be experiencing the same problem. I think this is a bug, but maybe it was a design decision. --erik -Original Message- From: Dmitry Rogatkin [mailto:[EMAIL PROTECTED]] Sent: Monday, February 05, 2001 4:32 PM To: [EMAIL PROTECTED] Subject: No path info for include page Is that normal for Tomcat?

Re: Speeding up database accesses
For one reason you are going to have a connection dedicated to that session even if it isn't using it, so you will have one connection per session when you really only need one connection per use which is likely to be MUCH smaller, especially considering the session doesn't die until session-timeout so you will have a buch of lame connection sitting around takeing up memory waiting to die.. A pool (especially a good one) will allow you to have only the number of connections you need available to you at any time.

RE: Speeding up database accesses
I hate it when other people beat me to the responses Basically, yes. Another reason is that some of the JDBC drivers taht I have worked with don't behave properly when garbage collected. Therefore, when the session dies, the Connection would die a garbage-collected death, sometimes leaving hanging connections. Yet another reason is when trying to deal with the JDBC-ODBC bridge and their problem of not handling concurrent connections. One connection per session makes it very difficult to limit the access. Its much easier where there is one class handling the the database traffic to implement this kind of traffic cop approach, or caching, etc. Lastly, it generally breaks the Model/View/Controller design philisophy to include the model (database) with the view (jsp) in the same class.

Hi, I'm trying to connect my Apache from one machine to my JBoss-Tomcat Applicationserver on another machine, both under Windows 2000. How do I do it? They are both running by them self but when I try to call the login.jsp site I cant connect... I've been trying to configure Apache and Tomcat by the help from the web but with no luck it just tells me how to connect if they are on the same machine(I think). Greatfull for any help...
