Tomcat Integration for ServiceMix 1.1 and ServiceMix 2.0

The following guide explains how to deploy ServiceMix 1.1 and ServiceMix 2.0 on the Apache Tomcat application server. For ServiceMix 2.0.1 and later releases, please refer to the Tomcat Integration document.

Pre-Installation Requirements

  • Java Developer Kit (JDK) 1.4.x or greater to run ServiceMix (to build Service, JDK 1.5.x or greater is required)
  • The JAVA_HOME environment variable must be set to the directory where the JDK is installed, e.g. c:\Program Files\Java\jdk1.5.xx.
  • Maven 1.0.2 or greater (required when installing source or developers' releases).
  • Apache Tomcat version 5.5
  • ServiceMix 1.1 or ServiceMix 2.0

The following platform was used to produce this document:

  • Windows XP
  • Tomcat 5.5
  • Java 5
  • ServiceMix 1.1 and ServiceMix 2.0

Deploying ServiceMix on Tomcat

Execute the following steps to deploy ServiceMix on Apache Tomcat. NOTE: This procedure will work on Unix platforms as well as the Windows platform, with the appropriate substitutions, such as using the backslash ( \ ) instead of the forward slash ( / ).

  1. Apache Tomcat must be downloaded and installed. For instructions please see the Tomcat web site.
  2. By default Tomcat uses port 8080. It is important to note if your Tomcat installation is on another port, such as port 80; this information will be used in a later step.
  3. Download and build the ServiceMix source code. Please see the Getting Started guide for instructions.
    NOTE: ServiceMix must be BUILT, as well as downloaded.
  4. Create the WAR file: 
    cd [servicemix_install_dir]\tooling\servicemix-web
maven war

    where servicemix_install_dir is the directory in which ServiceMix was downloaded and installed.

  5. To deploy the WAR file, servicemix-web.war, copy it to the Tomcat webapps directory. For example, on a Windows system: 
    cd [servicemix_install_dir]\tooling\servicemix-web\target
copy servicemix-web.war [tomcat_install_dir]\webapps

    where tomcat_install_dir is the directory in which Tomcat was installed.

  6. To deploy the ServiceMix WAR file, start and stop Tomcat.
  7. If there are errors indicating missing classes when Tomcat starts, perform the followng steps:
    1. Stop Tomcat.
    2. Install additional jar files in the deployed ServiceMix directory. The missing jar files are: commons-collections-3.1.jar and commons-pool-1.2.jar. These can be obtained by using a search engine and searching for them. Or they can found in your Maven repository, which is usually located in your_home_dir\.maven\repository. Specifically, your_home_dir\.maven\repository\commons-collections\jars and your_home_dir\.maven\repository\commons-pool\jars. 
        
copy commons-collections-3.1.jar [tomcat_install_dir]\webapps\servicemix-web\WEB-INF\lib 
copy commons-pool-1.2.jar [tomcat_install_dir]\webapps\servicemix-web\WEB-INF\lib
    3. Start Tomcat.
  8. The Tomcat console output should show ServiceMix starting:

Testing the ServiceMix Deployment on Tomcat

To ensure that ServiceMix is running on Tomcat do any of the following:

  1. Check the Tomcat console output or the Tomcat log files (see above) and look for servicemix-web starting without any errors.
  2. ServiceMix's default port is 1099. From another window run netstat and search for port 1099.
    From a Windows console, type: 
           
netstat -an|find "1099"


    OR

    From a Unix command shell, type:

    netstat -an|grep 1099


  3. Run the ServiceMix JMX Console. To do this enter the following URL in a web browser: http://localhost:8080/servicemix-web. Note: your installation of Tomcat may not be running on port 8080. If that is the case, replace 8080 with the correct port number in the previous URL.
    Try using the JMX console. For example, perform the following steps. Note: this is optional.
    1. Click on "Catalina".
    2. Click on "Unknown".
    3. Click on the "JMXServlet WebModule" to get monitoring information about the JMX Servlet itself:



  4. An http binding example is supplied. To run it on ServiceMix 1.1 do the following steps. To run it on ServiceMix 2.0 go to 2.0 steps.
    1. From a browser, enter the following URL: http://localhost:8080/servicemix-web/examples. Note: if Tomcat is using a different port, such as port 80, substitute the correct port number for 8080 in the URL.



    2. Click on the "perform a GET" link. If an HTTP 404 error occurs, go to the next step. If there is no error you will see:



    3. If there was an HTTP 404 error, the index.html file needs to be modified. The index.html file is located in the tomcat_install_dir\webapps\servicemix-web\examples directory. After editing the file, return to step 1. 
      Change this line: 
<li><a href="/jbi/exampleUri?x=123&name=James&location=London">perform a GET</a> into the HTTP binding</li>

to

<li><a href="/servicemix-web/jbi/exampleUri?x=123&name=James&location=London">perform a GET</a> into the HTTP binding</li>


    4. Use the ServiceMix JMX Console to see monitoring information on the httpBinding example just run.
      1. From a browser, enter the following URL: http://localhost:8080/servicemix-web. Note: If Tomcat is not running on port 8080, substitute the correct port number for 8080.
      2. Click on "org.servicemix."
      3. Click on "org.servicemix.jbi.framework.ComponentMBeanImpl". In the right-hand frame, scroll to the right to see statistics for the httpbinding example.




  5. To run the httpBinding example for ServiceMix 2.0 perform the following steps:
    1. Before attempting to run the example program, first check that the{{HelloWorldComponent.class}} file exists. Do a directory listing of the following and look for the file. 
      cd [tomcat_install_dir]\webapps\servicemix-web\WEB-INF\classes\org\servicemix\components

      where [tomcat_install_dir] is the directory in which Tomcat is installed.

    2. If the file HelloWorldComponent.class does not exist and possibly the directory components does not exist either, perform the following steps. If the file exists, go to
      1. Create the components directory in the ServiceMix source distribution: 
        cd [servicemix_install_dir]\tooling\servicemix-web\src\main\java\org\servicemix
mkdir components
      2. Copy the HelloWorldComponent.java file to the components directory created above. The HelloWorldComponent.java file can be created by cutting and pasting the following code: 
        package org.servicemix.components;

import org.servicemix.components.util.TransformComponentSupport;
import org.servicemix.jbi.jaxp.StringSource;

import javax.jbi.messaging.MessageExchange;
import javax.jbi.messaging.MessagingException;
import javax.jbi.messaging.NormalizedMessage;

public class HelloWorldComponent extends TransformComponentSupport {

    private String property;
    
    protected boolean transform(MessageExchange exchange, NormalizedMessage in, NormalizedMessage out)
            throws MessagingException {
        out.setContent(new StringSource("<hello>" + in.getProperty(property) + "</hello>"));
        return true;
    }

    public String getProperty() {
        return property;
    }

    public void setProperty(String property) {
        this.property = property;
    }

}
      3. Rebuild the servicemix-web.war file: 
        cd [servicemix_install_dir]\tooling\servicemix-web
maven war

        where servicemix_install_dir is the directory in which ServiceMix was downloaded and installed.

      4. Stop Tomcat.
      5. Remove the existing [tomcat_install_dir]\webapps\servicemix-web directory.
      6. Copy servicemix-web.war to the Tomcat webapps directory. For example, on a Windows system: 
        cd [servicemix_install_dir]\tooling\servicemix-web\target
copy servicemix-web.war [tomcat_install_dir]\webapps

        where tomcat_install_dir is the directory in which Tomcat was installed.

      7. Start Tomcat to deploy the ServiceMix WAR file.
    3. To run the example: from a browser, enter the following URL: http://localhost:8080/servicemix-web/examples. NOTE: If Tomcat is using a different port, such as port 80, substitute the correct port number for 8080 in the URL.
