Private JVM (Java Virtual Machine),
Private Tomcat Server
Alden Hosting offers private JVM (Java Virtual Machine), Java Server Pages (JSP), Servlets, and Servlets Manager with our Web Hosting Plans
WEB 4 PLAN and
WEB 5 PLAN ,
WEB 6 PLAN .
At Alden Hosting we eat and breathe Java! We are the industry leader in providing
affordable, quality and efficient Java web hosting in the shared hosting marketplace.
All our sites run on our Java hosing platform configured for
optimum performance using Java 1.6, Tomcat 6, MySQL 5, Apache 2.2 and web
application frameworks such as Struts, Hibernate, Cocoon, Ant, etc.
We offer only one type of Java hosting - Private Tomcat. Hosting accounts on the Private
Tomcat environment get their very own Tomcat server. You can start and re-start
your entire Tomcat server yourself.
The Apache Tomcat Servlet/JSP Container - Building Tomcat | The Apache Tomcat Servlet/JSP Container |  |
| Links User Guide Reference Apache Tomcat Development | Introduction |
Building Tomcat from SVN is very easy, and is the first step to contributing to
Tomcat. The following is a step by step TODO list.
|
Download and install a Java Development Kit 1.4.x or later |
The default distribution of Tomcat .x requires a 5.0 or later JDK. Tomcat
can be built using a 1.4.x JDK but you will need to copy the contents of the
compat directory (created by the build process) to your build directory before
Tomcat will start.
The Sun JDK can be downloaded here.
IMPORTANT: Set an environment variable JAVA_HOME to the pathname of the
directory into which you installed the JDK release.
|
Install Apache Ant 1.6.2 or later |
Download a binary distribution of Ant 1.6.2 or later from
here.
Unpack the binary distribution into a convenient location so that the
Ant release resides in its own directory (conventionally named
"apache-ant-1.6.x"). For the purposes of the remainder of this document,
the symbolic name "${ant.home}" is used to refer to the full pathname of
the release directory.
Create an ANT_HOME environment variable to point the directory ${ant.home},
and modify the PATH environment variable to include directory
"${ant.home}/bin" in its list. This makes the "ant" command line script
available, which will be used to actually perform the build.
|
Building Tomcat |
Download the main build.xml script from here.
Create a new directory, and copy the newly download build.xml to it. This
directory will be referred to as the ${tomcat.source} directory in the rest
of this document.
Go to that directory, and do:
cd ${tomcat.source}
ant
NOTE: Users accessing the Internet through a proxy must use a properties
file to indicate to Ant the proxy configuration. Read below.
WARNING: Running this command will checkout the Tomcat 5 sources from SVN, as
well as download binaries to the /usr/share/java directory.
Make sure this is appropriate to do so on your computer. On Windows,
this usually corresponds to the C:\usr\share\java directory,
unless Cygwin is used. Read below to customize the directory used
to download the binaries.
The build can be controlled by creating a ${tomcat.source}/build.properties
file, and adding the following content to it:
# ----- Proxy setup -----
# Uncomment if using a proxy server.
#proxy.host=proxy.domain
#proxy.port=8080
#proxy.use=on
# ----- Default Base Path for Dependent Packages -----
# Replace this path with the directory path where
# dependencies binaries should be downloaded.
base.path=/usr/share/java
|
Updating and rebuilding Tomcat sources |
It is recommended to regularly update the downloaded Tomcat 5 sources.
To do this, execute the following commands:
cd ${tomcat.source}
ant checkout
For a quick rebuild of only modified code you can use:
cd ${tomcat.source}
ant build
|
Building with Eclipse |
Important:
This is not a supported means of building Tomcat; this information is
provided without warranty :-).
The only supported means of building Tomcat is with the "ant build"
described above.
However, some developers like to work on Java code with a Java IDE,
and the following steps have been used by some developers.
Note that you must complete all the above steps to fetch
the repositories and build some JAR files the first time.
After you have completed the above steps, you can set up a
series of Eclipse 4 projects.
Note that this will not let you build everything under Eclipse;
the build process requires use of Ant for the many stages that aren't
simple Java compilations.
However, it will allow you to view and edit the Java code,
get warnings, reformat code, perform refactorings, run Tomcat
under the IDE, and so on.
Use Windows->Preferences and then Java->Build Path->Classpath
Variables to add two new Classpath variables:
TOMCAT_LIBS_BASE | the base path where the binary dependencies have been downloaded |
ANT_HOME | the base path of Ant 1.6.2 or later |
Use File->New Project to create a new Java project
for each of the binaries repository (e.g., /usr/share/java),
container, connectors, jasper, servletapi.
Unless you thought ahead to make the ${tomcat.source} directory be under
your Workspace folder, tell Eclipse the external location using "Import/Export...",
General->Existing Project into Workspace.
Eclipse .project and .classpath files are provided in each of these
directories so Eclipse should find all source trees and jars, and
hopefully compile without problems. Note that these
files assume you are using Eclipse with a 5.0 or later JDK; also, the
connectors module must be built with a compiler compliance level of 5.0.
To run Tomcat without a special IDE plug-in, you can simply use Run->Run...
enter "org.apache.catalina.startup.Catalina" as the main class,
"start" as program arguments, and
"-Dcatalina.home=..." (with the name of your build directory)
as VM arguments.
Note also that due to the way the Tomcat source is assembled
from several SVN projects, you may not be able to use the Eclipse
SVN client to update (nor to commit, if you are a committer).
Use the external SVN client of your choice, then use the
Eclipse PackageExplorer or Navigator "Refresh" context menu item
to tell Eclipse that you've updated the files.
|
Building with other IDEs |
The same caveats apply as for Eclipse, above.
The same general idea should work in most IDEs; it has been reported
to work in Idea, for example.
