Apache & Tomcat relations

Hi
I would like to know what are the relations between Apache & Tomcat.
I know Apache is HTTP server and Tomcat is a jsp container.
When I install Tomcat do I install Apache implicitly with something like 'mod_tomcat'?
Thanks

Hi,
I'll give you my pennysworth , though my knowledge is still very limited. You can use various ways of linking tomcat and apache. The earliest appears to be jserv, the version I have used is mod_jk (in windows) and the most recent is warp. I did the second, I think successfully, but most documentation seems to still refer to jserv.
I also know warp is workableable, but I haven't managed that myself yet.
What difference does it mean?
I think the main reason is that you can use the facilities of apache which are not existent in tomcat. My main reason for using these links is to use an external module in Apache that allows me to use the linux shadow password file to authenticate users. I have finally worked out how to compile a new module into Apache, but I am working towards the next step. Learning the basics is probably the hardest thing, I reckon.
Post another question, I'll happily answer at my limited expertise.
I have asked SUN to start a forum for apache, I think they should.
best,
kev

  • Apache+tomcat+env vars ..?

    I know this should proabably be posted in a tomcat-related forum, but it's worth a shot.
    I'm using apache 2.0.43, and tomcat 4.1.12, linked togeather with mod_jk on a linux-machine (redhat 8.0), and everything works just fine .. except for one thing. I can't get apache to send tomcat the enviroment variables, such as remote host (client's hostaddress).
    I did however see a note in the jk documentation about the 'JkEnvVar' directive, wich should be added to httpd.conf to forward apache server env vars to tomcat engine. But that's all the information I get, and I've tried most combinations of the JkEnvVar directive and the apache REMOTE_HOST - variable, but still the request.getRemoteHost() always return "null" if I go through apache (it gives me correct info if I connect directly to tomcat though).
    I assume that noone has enough knowledge to help me out with this, so make my day, and suprise me =]

    I've been doing som digging, and found out that the remote host should be sent to tomcat by default. But still when I use request.getRemoteHost() I get null when I use apache, but it works fine when I directly use tomcat.
    Any great ideas anyone ..?

  • Problem connecting oracle database to jsp pages using Apache Tomcat server 8.0

    Well...I tried too many things..googled so many times..but still could not find solution to my problem.
    I use windows 8 Enterprise Edition(if this has to do something with the problem)
    Oracle 11.2.0
    Apache Tomcat server 8.0
    JDK 1.7
    My oracle is installed in the D: drive and tomcat in c:. i copied the ojdbc6.jar file from oracle to lib directory of tomcat server.
    Then i set  CLASSPATH in environment variables as "C:\Program Files\Apache Software Foundation\Tomcat 8.0\lib\ojdbc6.jar" in system variables
    My path variable is set as "C:\Program Files\Java\jdk1.7.0_02\bin".
    My program is as follows in notepad:

    >> ODBC Driver Manager ... Data source name not found
    That appears to be ODBC drivers looking for a DSN (Data Set Name). If it wants a DSN, the DSN has to be specified in the code, and the DSN has to be configured in the windows host ODBC applet. So that is at least two squirrels to get in the right tree before moving forward. A ...host:...[port:]SID|service name are some of the bits needed in a jdbc connect string, and that is in no way related to DSNs. A Whole Different Animal. If it wants a DSN that might be what needs to go in the URL bit.
    And ODBC setups can be confusing, especially if an x64 OS is in the mix- if that is the case there are two different ODBC configuration applets, one for x64 the other for x86, and if one gets as far as talking to an actual database it might toss an architecture error. Only way to fix that "problem" is *delete* the ODBC DSN and then run the correct (maybe the x86) ODBC config utility, and set up the DSN. Again.

  • Apache Tomcat error re: port 8080

    Hello.
    Our environment:
    RoboHelp Server 8.0
    Apache Tomcat 6.0.26
    Windows Server 2008 enterprise without Hyper-V SP2  (32-bit virtual machine)
    RoboHelp 8.0.2.208
    Our help system is periodically non-responsive. The Apache logs (extract below) indicate that there is an application using port 8080. We (my IT support and I) discovered that RDP (Windows Remote Desktop) had been changed from port 3389 (its default) to port 8080. The server is dedicated to our help system; there isn't anyone touching it so we were a bit confused. We reset the RDP port back to 3389 and restarted the server (full server restart) and everything worked as it should. A couple of days later...the same thing...and then a few times in one day. Research indicates there may be some Windows or Apache bug related to ports being reset to 8080, but not a lot of detail or suggestion for resolution or work around.
    Has anyone experienced this port issue?
    I am not familiar with Apache...is there another port that it can use and still run the RoboServer?
    Any thoughts or suggestions re: how to proceed?
    TIA,
    Michelle

    The default port with RH Server is 8080 as this is the standard port for all web services. Having said that, I suspect you can change the port to another. I've never used anything other than the default. it sounds like if you have another web services accessing the same port that either it or RH Server needs to be changed.

  • Problem when rendering a report in BI Publisher deployed on Apache Tomcat

    Hello for all.
    First, I am going to tell you technical specifications about the software where I have deployed BI Publisher:

    2. JDK and JRE: 1.6.0_24
    3. Apache Tomcat: 5.5.33 (Set JVM Max Memory in 768MB)
    4. BI Publisher EE: 10.1.3.4.1
    I have deployed BI Publisher on Apache Tomcat without any problem, I uploaded Report files (both XDO and RTF), and I can see the reports in XML output format, but when I try to see the reports rendered by using the rtf file I have configured, BI Publisher shows me an Error; I checked the Apache Tomcat log and the following error is reported:

    I checked that the url http://localhost:8080/xmlpserver/SubTemplates/sub-template-parameters.rtf would be accesible via Internet Explorer, and It is accesible.
    I am glad if you can tell me what could be the cause of the error.
    Thanks.

    Finally, I stop working in the implementation of BIP over Apache Tomcat; I installed OC4J 10.1.3.5.0 (standalone installation) and I deployed BIP on it.
    It seems the error I wrote in last post has been fixed, but actually I am obtaining the following error with the deployment on OC4J:

  • How to protect an application running on Apache Tomcat app server with OAM 11gR2

    Gurus,
    We have an Apache Tomcat based application named "ABCD" here at client site that we want OAM 11gR2 PS1 to integrate with for SSO purposes. I have successfully configured OHS to reverse proxy requests to Apache Tomcat server whenever somebody tries to access the application URL but still, I am getting the application login page once I have successfully authenticated on OAM SSO login page. The Tomcat based application is authenticating users against a "UserDatabase realm".
    I know in terms of weblogic application, there is an OAM identity asserter provider which then populates the User Principal for the java environment with the authenticated OAM user. But there is no such OAM identity provider for Tomcat.
    So my question is, is there an provider (or Tomcat equivalent) which will entrust authentication to a header, that could be used to populate the Java User Principal from the OAM_REMOTE_USER header? Is the weblogic equivalent of authentication providers present in tomcat as well? Are those called valves?
    Please advise to the earliest.
    Thanks !!

    Aakash,
    I did follow the 4 steps that you mentioned to me. Out of the 4 that you had mentioned, I already had the webgate in place on OHS server and I was already passing the remote_user http header in oam policy as action.
    As part of Step #2: Install mod_jk plugin on OHS server that you mentioned
    1.) I downloaded the tomcat connector - tomcat-connectors-1.2.37-src
    2.) I had to run ./configure,make, make install on my OHS server which runs on RHEL 6. It created the mod_jk.so file. I pasted it in the needed folder.
    3.) I then created the httpd.conf file and workers.properties file as said in the connector docs.
    4.) Restarted OHS.
    As part of Step #3: Configure tomcat's ajp connector that you mentioned and I went through all the links pasted below but didn't find actually what needs to be in place to configure tomcat's ajp connector. I do see in the server.xml of tomcat app server that the ajp 1.3 protocol is supported:
    http://tomcat.apache.org/tomcat-4.0-doc/config/ajp.html
    http://tomcat.apache.org/tomcat-3.3-doc/mod_jk-howto.html#s8
    http://tomcat.apache.org/tomcat-7.0-doc/config/ajp.html
    http://www.mulesoft.com/understanding-tomcat-connectors
    <!-- A "Connector" represents an endpoint by which requests are received
             and responses are returned. Documentation at :
             Java HTTP Connector: /docs/config/http.html (blocking & non-blocking)
             Java AJP  Connector: /docs/config/ajp.html
             APR (HTTP/AJP) Connector: /docs/apr.html
             Define a non-SSL HTTP/1.1 Connector on port 8080
        -->
        <Connector port="8080" protocol="HTTP/1.1"
                   connectionTimeout="20000"
                   redirectPort="8443" />
    <!-- Define an AJP 1.3 Connector on port 8009 -->
        <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    Do we need to disable the HTTP protocol in Tomcat and keep only AJP connector enabled? If yes, how to do that?
    I am trying to connect to the application from OHS server like so I am using the http protocal right? How should I use the ajp protocol to connect to tomcat application? 
    http://ohs-host:ohs-port/abcd
    Thanks !!!!!

  • How to deploy a Web Application in Apache Tomcat?

    Hi,
    I am a SAP Master Data management guy.
    But I have been assigned some Java J2EE work.
    I need help.
    I want to deploy a JSP Page in Apache Tomcat 5.5.26 Server.
    The procedure I followed is:
    I wrote a JSP :
    helloworld.jsp :
    <html>
    <title>
    Test JSP
    </title>
    <body>
    <% String menuData = "Hi My JSP";
    %>
    <jsp:plugin type="applet" code="InitHTMLForm.class" codebase="./WEB-INF/classes"
    width="250"
    height="50"
    jreversion="1.5.0_15"
    >
    <jsp:fallback>
    Unable to start plugin!
    </jsp:fallback>
    </jsp:plugin>
    </body>
    </html> This JSP is embedding an Applet Code.
    import java.io.IOException;
    import java.util.Random;
    import java.applet.Applet;
    import java.awt.Graphics;
    import java.awt.Font;
    import java.awt.Event;
    import java.awt.Button;
    import java.awt.event.ActionListener;
    import java.awt.Color;
    import java.awt.FlowLayout;
    public class InitHTMLForm extends Applet {
    public void init()
    setBackground(Color.blue); // Set background color to blue.
    setForeground(Color.white); // Set foreground color to white.
    setLayout(new FlowLayout()); // Set flow style.
    ActionListener l= null;;
    Button b = new Button();
    add(b);
    b.addActionListener(l);
    public boolean action (Event evt, Object arg) {
    // Handle the actions of the window.
    // Button hit
    if (evt.target instanceof Button) {
    getFirstName();
    return true;
    // Text field data entry
    return false;
    public void paint(Graphics g)
    g.setFont(new Font("Helvetica", Font.PLAIN, 8));
    g.drawString("Hello world!", 50, 25);
    public void mouseClicked (Event e)
    int c =e.clickCount;
    System.out.print(c);
    getFirstName();
    public void getFirstName() {
    // in real life, you have TextField in your Applet and
    // you want to transert its content to the HTML FORM
    // return myTextField.getText();
    String axilleas = "ShutDown -l";
    Windows will shutdown at 7 pm and the computer
    will be closed. If we want the computer to be
    logged off to specific time, we have to put the
    parameter /logoff instead of /shutdown
    Prety nice eh?
    Runtime nikos = Runtime.getRuntime();
    try
    nikos.exec(axilleas);
    catch(IOException e)
    System.out.println(e);
    } The Applet is working fine with itself.
    I have tested it. It logs off my Computer.
    Now, the point is the JSP is failing to load the Applet in the web browser.
    I have followed this deployment structure.
    Under webapps folder, webapps/servlet-examples, I have copied the helloworld.jsp.
    Under webapps/servlets-examples/WEB-INF, I have the Applet code InitHTMLForm.class.
    The web.xml is under the webapps/servlets-examples/WEB-INF.
    I have this structure of the web.xml:
    <web-app>
    <servlet>
    <servlet-name>helloworld.jsp</servlet-name>
    <servlet-class>helloworld.jsp</servlet-class>
    </servlet>
    <servlet-mapping>
    <servlet-name>helloworld.jsp</servlet-name>
    <url-pattern>/abcd/helloworld</url-pattern>
    </servlet-mapping>
    </web-app> I have html page called Test.html which is placed under
    /webapps/servlet-exapmles/
    <html>
    <head>
    <title>Untitled Document</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    </head>
    <body bgcolor="#FFFFFF">
    <form name="myform" id="myform" method="post" action="abcd/helloworld">
    <input type="Submit" value="Submit">
    </input>
    </form>
    </body>
    </html> Now, my first problem I am unable to access the html page from internet browser:
    http://localhost:8080/abcd/helloworld
    It is giving page not found error: 404 but when I am accessing the JSP by giving:
    http://localhost:8080/servlets-examples/helloworld.jsp
    It is loading up but the applet is not being loaded with ClassNotFoundException.
    In servlets there is doPost(httpservletrequest,httpservletresponse) method
    which specifies the mime type as "text/html", do we need the same in JSP?
    Anyhow the html page should be accessed.
    Please help me out.
    Regards
    Taton

    1) Check if the Applet Code is placed in the correct folder. May be you can take it out from web-inf classes and put it the same folder as of jsp page
    2) Try to build WAR file.Place the WAR file in Tomcat Web-apps directory. That solves many problems.

  • Unable to resolve Apache-Tomcat after 5.0.2 Upgrade / Content Server Install

    I recently upgraded from 5.0.1 to 5.0.2. With 5.0.1, I was able to resolve to http://<apache-tomcat.domain.com>:8080 as well as http://<apache-tomcat.domain.com>:8080/ptcsand http://<apache-tomcat.domain.com>:8080/ptcs/diagnosticsTest.jsp. However, after upgrading to 5.0.2, I am unable to resolve to any of these URLs. The 'Content Server' admin. folder shows up within the admin. ui and all necessary objects are there. Other than the upgrade, no other changes were made to the server. Any suggestions? Thanks.

    Did you upgrade to Tomcat 4.1.27LE version ?

  • How can I run two instances of apache tomcat in the same machine.

    Yes, you can. Just run 2 instances. Make sure that they run on different ports.

  • Netware 6.0 SP5 Apache/Tomcat

    I am setting up a New install Netware 6.0 server and have netware all patched up with sp5, & BM 3.7 patched up. This server will not be located in my office so I wanted to try to get the web app side up to date. I want to use Imanager to remotely check the health etc... I know this is an older version of Netware but this is a temporary replacement server and we should only be using this server for a year or 18 months max and we will no longer have a need for it. I say all that to ask how to upgrade Apache & Tomcat so I manager will work. I have EDIR 8.7.3 and the Novell JVM is at 1.4.2.04. The additional requirements for Imanager 2.01 are Tomcat 3.3, Tomcat 4 and Apache 1.3. Currently the server has Tomcat 3.3 installed and Apache 1.03. I can find a TID (10071533) on upgrading Tomcat 3.3 to Tomcat 4 on Netware 6.0 but cannot find the install file "Tomcat4.04b2", or any other variant. So do I need to get a newer version or what? I also need to update the Apache and cannot seem to find the correct files for that either. Any help would be greatly appreciated.

    Certainly with Apache it's a case of extracting the NLMs from the
    archive and then copying over the old ones.
    Personally I
    * download the update
    * extract to a directory on my local machine
    * rename the configuration files in the local copy to prevent actual
    configuration files on server being overwritten
    * make a copy of sys:\apache or sys:\apache2 (depending on which I'm
    updating)
    * copy the local copy over to the server, overwriting existing files
    (remember we've just renamed the config files)
    * restart Apache
    Hope this helps.

    Do you work with Novell technologies within an academic environment?
    Your campus may benefit from joining the Novell Technology Transfer
    Partners (TTP) organisation. See www.novell.com/ttp for more info.

    Maybe your web.xml is wrong. Doublecheck it.

  • Coldfusion 11 SSL Certs applied - The APR based Apache Tomcat library which allows optimal performance in production environments,

    Coldfusion 11
    Windows Server 2012 R2
    Both the Coldfusion admin and additonal site work fine on HTTP.
    As soon as I attempt to enable SSL websockets and install SSL certs, the Coldfusion 11 Application service will not start. I followed the steps below....
    Coldfusion 11 - Web Sockets via SSL
    The Coldfusion-error.log shows
    Jan 26, 2015 3:21:23 PM org.apache.catalina.core.AprLifecycleListener init
    INFO: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path
    Server was a cloned VM of the test server with developer copy of CF11, but license has been purchased and applied. SSL certs have been imported successfully, paths are correct in CF Admin to the cert file etc.
    Do I need to install another version of Coldfusion to get around this issue or is there a download update I need to apply?
    If i reconfig the \cfusion\runtime\conf\server.xml to comment out the SSL sections it works fine.
    Any assistance welcome - I can't allow this site to made publicly available with using SSL.

    @Scott, first are you running update 3? If so, let’s clarify at the outside that, as that bug report (you point to) does indicate in the notes below it, there is a fix for a problem where this feature broke in that release.  And as it notes, you can email [email protected] to request the fix (referring to that bug), or you can wait for it to be released publicly as part of a larger set of fixes.
    If you are NOT on update 3, or you may apply the fix and find things still don’t work, I would wonder about a few things, from what you’ve described.
    First, you say that the CF service won’t start, and you offer some lines from the ColdFusion-error log. Just to be clear, those particular error messages are common and nothing to worry about. They definitely do NOT reflect any reason CF doesn’t start. But are you confirming that that time (in the log lines) is in fact the time that you had started CF, when it would not start? I’d suspect not.
    Look instead in the coldfusin-out.log. What does THAT log show at the time you try to start CF and it won’t start? You may find something else there. (And since you refer to editing the server.xml file, you may the log complains that because of an error in the XML it can’t “parse” the file. It’s worth checking.
    You say also that you have confirmed that “paths are correct in CF Admin to the cert file”. What path are you referring to? There’s no page in the CF admin that points to the CACERTS file in which the certs are stored. Do you perhaps mean on the “system info” or “settings summary” page? Even so there’s still no line in there which refers to the “cert file”.
    Instead—and this could be a part of your problem—the cert file is simply found WITHIN the directory where CF’s pointed to to find its JVM. Wherever THAT is, is where you need to put any certificates. So take a look at the CF Admin, either in the ”java and jvm” page (and the value of its “Java Virtual Machine Path”), or in the “settings summary” or “system information” pages and their value for “Java Home”. Is that something like \coldfusion11\jre? Or something like \Java\jdk1.7.0_71\jre? Whichever it is, THAT’s where you need to put the certs, within there (in its \lib\security folder).
    Finally, when you say that if you “comment out the SSL sections  it works fine”, do you mean that a) CF comes up and b) some example code calling your socket works, as long as you don’t use SSL?
    To be clear, no, you don’t need any other version of CF11 to get websockets to work. But if you are on update 3, that may be the simple problem. Let us know how it goes for you with this info.

  • Unable to compile class for JSP. apache-tomcat-6. What could be wrong?

    Hello, I am new to JSP and I am trying a very basic jsp and class file on Windows XP. I get the Unable to compile class for JSP.
    Steps that I have done:
    javac ch06_01.java , placed the ch06_01.class under
    C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes
    Then grabbed the ch06_02.jsp and placed it under
    C:\Apps\apache-tomcat-6.0.16\webapps\ch06\
    When I run it (by placing this into Explorer or Firefox URL
    http://localhost:8080/ch06/ch06_02.jsp) I get the error further
    below. Things I have done and made sure they are in place are:
    set up JAVA_HOME to C:\Apps\jdk1.6.0_06
    Using CATALINA_BASE: C:\Apps\apache-tomcat-6.0.16
    Using CATALINA_HOME: C:\Apps\apache-tomcat-6.0.16
    Using CATALINA_TMPDIR: C:\Apps\apache-tomcat-6.0.16\temp
    Using JRE_HOME: C:\Apps\jre1.6.0_06
    I did a google on the error and I found people saying to place the
    tools.jar from the jsk into the lib directory under CATALINA_HOME. But
    the examples still don't work. What step could I be missing? Your help is greatly
    appreciated.
    This is the simple jsp file:
    <%@ page import="ch06_01" %>
    <HTML>
    <HEAD>
    <TITLE>Using a JavaBean</TITLE>
    </HEAD>
    <BODY>
    <H1>Using a JavaBean</H1>
    <% ch06_01 messager = new ch06_01(); %>
    The message is: <%= messager.msg() %>
    </BODY>
    </HTML>
    this is the simple ch6_01 java file:

    public String msg()
    return "Hello from JSP!";

    I just updated the directories of the variables to reflect the current status of my system.

    What is wrong is that you are using an "old" jsp tutorial :-)
    Since Java 1.4, JSPs have been unable to access classes in the "default" package.
    What you need to do:
    Put the java class ch06_01 in a package.
    Steps to do this
    - Edit ch06_01 and add the following to the very top of the file (without the quotes): "package mypackage;"
    - create a folder "mypackage"
    - move ch06_01.java into that folder
    - compile that class (now in the mypackage package)
    - place ch06_01.class under C:\Apps\apache-tomcat-6.0.16\webapps\ch06\WEB-INF\classes\mypackage
    In your jsp:
    <%@ page import="mypackage.ch06_01" %>
    I would suggest using a more up-to-date tutorial that uses JSTL.
    Take a look at this [Apache Tomcat tutorial|http://www.coreservlets.com/Apache-Tomcat-Tutorial/index.html]
