installation-ubs.xml installation-was.xml
Log:
(Submitted by Ted Husted). Per Craig's suggestions: * Make the page names include
just the server name, and not
the version number. That way, you can have separate sections
on the page for each individual version of the same server. New
sections can be conveniently added to the bottom as new versions
of the servers come out. Maybe include a hyperlink index at the
top of each page for all the documented version numbers?
* On the Tomcat page, I've seen so many problems with bugs in
Tomcat 3.1 that I do not recommend it as a platform for Struts
based apps. I'd like to have the install documents recommend
that people upgrade to at least Tomcat 3.2.1.
* The Tomcat instructions related to integration with Apache apply
only to 3.1 and 3.2 -- the instructions for 4.0 will be different.
Right
now, the 4.0 section should just talk about running stand alone,
though -- the 4.0 web connector is not ready for prime time.

<h3><a name="wls5">Weblogic 5.1 (service pack 8)</a></h3>
<ul>
<li>Obtain and install the Xerces XML parser (problems have been reported with
the Sun reference implementation). Put xerces.jar in your WebLogic system
path.</li>
<li>Obtain and unpack the Struts binary distribution (this procedure assumes
it was extracted to <code>c:\jakarta-struts</code>).</li>
<li>Add an entry to weblogic.properties for each of the Struts web applications
that you would like to configure. For example, to make the struts-example
application available, add the following line to weblogic.properties:<br/>
<code>weblogic.httpd.webApp.strutsexample=<br/>
c:/jakarta-struts/webapps/struts-example.war</code></li>
<li>You do not need to include struts.jar or any of the application specific
classes in the WebLogic classpath, since this will be done automatically (unless
deploying an unpacked web archive- see below).</li>
<li>Start WebLogic server and point your web browser to the struts application.
For example, to connect to the example application added in step 3:<br/>
<code>http://localhost:7001/strutsexample</code></li>
<li>This example application depends on the Struts specific resource file
ApplicationResources.properties
to be present on the classpath. However, WebLogic only extracts *.class files
from the archive so this file will not be found, resulting in an error the
first time it is needed- something similar to: javax.servlet.ServletException:
runtime failure in custom tag 'message'. Steps 6 & 7 will need to be
performed
for this application, and any other that relies on
ApplicationResources.properties.</li>
<li>Extract ApplicationResources.properties from the *.war file, and manually
copy it to the respective package in the _tmp_war_ directory WebLogic created
for this application. Again referring to the struts-example application, this
would be:<br/>
<code>c:\jakarta-struts\webapps\WEB-INF\_tmp_war_strutsexample</code></li>
<li>Restart WebLogic. You will now be able to run the application:<br/>
<code>http://localhost:7001/strutsexample</code></li>
</ul>
<p>The above steps should be followed for applications deployed as *.war files.
For unpacked web applications, configuration involves adding both
<code>struts.jar</code>
and <code>/WEB-INF/classes</code> to the WebLogic classpath. For this reason,
I would suggest deploying applications as war files to WebLogic. However, the
same example application can be successfully deployed in extracted format by
modifying weblogic.properties (assuming the war was extracted to directory
webapps/struts-example):</p>
<p><code>weblogic.httpd.webApp.strutsexample=<br/>
c:/jakarta-struts/webapps/struts-example/</code></p>
<p>And starting WebLogic with the updated WebLogic classpath. For example:</p>
<p><code>c:\jdk1.3\bin\java -ms16m -mx64m<br/>
-classpath c:\weblogic\lib\weblogic510sp8boot.jar;</code></p>
<hr/>
<h4>Additional Recommendations</h4>
<ul>
<li>Servlet and JSP-Reloading should be turned off. First, you pay a performance
penalty. Depending on the number of JSPs, the number of requests and the
configured checking interval, the server will slow down. Second, with JSP- and
Servlet reloading, one opens the door for various Weblogic classloader
problems,
that are difficult to diagnose, difficult to handle and often lead to lost
HTTP-sessions.</li>
<li>Set the name of the <code>sessionid</code> to <code>JSESSIONID</code>, if
cookies are used for session
tracking and to jsessionid, if sessions are URL-based. (There are additional
problems related to URL-based sessions, caused from BEA's way to encode the
session
id (J2EE-incompatible) as query-param. Especially <bean:include> will
not work with
URL-based sessions yet. However, using the correct session name solves at
least some
problems.)</li>
<li>Configure the JSP-Servlet registration in <code>weblogic.properties</code> for
maximum J2EE-compliance and/or for maximum performance.</li></ul>
<p>The JSP-Servlet supports some initialization parameters that can be customized
to get
best performance, maximum compliance or (as shown below) easier debugging:</p>
<pre>
weblogic.httpd.initArgs.*.jsp=\
pageCheckSeconds=-1,\
setEmptyStrings=false,\
compileCommand=./_jspCompiler_.cmd,\
workingDir=/weblogic/myserver/tmp_classfiles,\
keepgenerated=true,\
debug=true,\
verbose=true
</pre>
<p>In the above example, the batch file (<code>_jspCompiler_.cmd</code>) invokes
jikes
which results dramatically reduced startup times (jikes is about three times
faster
than javac.) The batchfile contains only a single line:</p>
<pre>@jikes -g -nowarn %*</pre>
<p>The next configuration could be used when all tests have been done and speed is
the
major concern ...</p>
<pre>
weblogic.httpd.initArgs.*.jsp=\
pageCheckSeconds=-1,\
setEmptyStrings=false,\
compileCommand=./_jspCompiler_.cmd,\
workingDir=/weblogic/myserver/tmp_classfiles,\
keepgenerated=false,\
debug=false,\
verbose=false
</pre>
<p>... together with ...</p>
<pre>@jikes -O -nowarn %*</pre>
<p>Weblogic supports similar settings through <code><context-params></code> in
<code>web.xml</code>
(Please read the latest documentation at the BEA website for details.)</p>

<h3><a name="jr30">JRUN 3.0 SP2A, VERSION 3.02A.11614</a></h3>
<b>Tested with: Microsoft IIS 5.0, Windows 2000</b>
<h4>Important Note:</h4>
<p>At the moment, JRun is not fully compliant with the JSP 1.1/1.2
specification. </p>
<p>Specifically, the automatic type conversions for custom tag parameters
specified in "Issue 7" of the JSP 1.1 Errata and in the JSP 1.2 Proposed
Final Draft have not yet been implemented.</p>
<p>As it stands, JSP pages that make use of Struts taglibs whose parameters
require conversion (such as booleans) will not compile under JRun. This
includes the Struts Example Application. Attempting to run the example
application will result in an exception similar to the following being
thrown:</p>
<pre>
/struts-example/index.jsp:
javax.servlet.ServletException: Compilation error occured:

<p>The following instructions describe how to install the Struts Example
Application under JRun. A subsequent section describes how the Struts Example
Application can be patched to work with Struts</p>
<p>The following instructions assume the following:</p>
<ul>
<li>JRun has been installed and integrated with the web server of choice.</li>
<li>$APP_SERVER_NAME is the name of the application server used to host the
application. (When JRun is first installed, it creates an application
server called JRun Default Server).</li>
<li>$APP_SERVER_DIR is the directory used to hold applications hosted by
$APP_SERVER_NAME. For the JRun Default Server, the directory is
$JRUN_HOME/servers/default where $JRUN_HOME is the directory where
JRun is installed.</li>
</ul>
<h4>Installing the struts example application</h4>
<ul>
<li>Login to the JRun Management Console.</li>
<li>On the left pane, select $APP_SERVER_NAME. A page showing the
current server status will be shown on the right pane.</li>
<li>On the right pane, click on the WAR Deployment link. A page
containing a list of the currently deployed web applications will be
shown.</li>
<li>On the right pane, click on Deploy an Application. Complete the Web
Application Information form as follows:</li>
<ul>
<li>Servlet War File or Directory: Enter the full path where
struts-example.war is found or click on Browse to select
the path.</li>
<li>JRun Server Name: $APP_SERVER_NAME</li>
<li>Application Name: Struts Example</li>
<li>Application Hosts: All Hosts</li>
<li>Application URL: /struts-example</li>
<li>Application Deploy Directory: will default to
$APP_SERVER_NAME/Struts Example (or the name as specified for
Application Name).</li>
</ul>
<li>Once the form is complete, click on the Deploy button.</li>
<li>If deployment is successful, restart the application server by
clicking on <code>$APP_SERVER_NAME</code> on the left pane. A page showing the
current server status will be shown on the right pane. Click the
Restart Server button to restart the application server.</li>
<li>Test the sample application by using the following URL in the
browser:<br/>
<code>http://hostname/struts-example/index.jsp</code><br/>
The struts-documentation.war can be installed using the same
procedure.</li>
</ul>
<h4>Installing unpacked web applications</h4>
<p>The above steps should be followed for applications deployed as
<code>*.war</code> files.</p>
<p>For unpacked web applications, configuration involves the following steps:</p>
<ul>
<li>From the JRun Management Console, select <code>$APP_SERVER_NAME</code> (on the
left pane) and click on WAR Deployment (on the right pane).</li>
<li>On the right pane, click on Create an Application and complete the
Web Application Information form as follows:</li>
<li>JRun Server Name: $APP_SERVER_NAME</li>
<ul>
<li>Application Name: myApplication</li>
<li>Application Hosts: All Hosts</li>
<li>Application URL: /myApplication</li>
<li>Application Deploy Directory: will default to<br/>
<code>$APP_SERVER_NAME/myApplication</code></li>
</ul>
<li>Click on Create to submit the form.</li>
<li>Once the web application is created, install and configure the struts
components (struts.jar, struts*.tld, etc) for the web application under
<code>$APP_SERVER_NAME/myApplication/WEB-INF</code></li>
<li>Install the remaining components of the application: .class files,
JSP pages,.properties files etc as required.</li>
<li>To configure the extension mapping of the request URI (ie *.do) to
the action servlet, expand <code>$APP_SERVER_NAME</code> on the left pane, expand
the Web Applications branch and click on myApplication. The right pane
will display the configuration options for myApplication. Click on
Servlet URL Mappings. A list of existing mappings will be shown. Click
the Edit button and create the following entry:</li>
<ul>
<li>Virtual Path/Extension: *.do</li>
<li>Servlet Invoked: action</li>
</ul>
<li>Click on the Update button to save the changes.</li>
<li>Restart the application server.</li>
<li>The application should now be accessible from the browser.</li>
</ul>
<p>The JRun application server will need to be restarted each time one of the
following changes are made to the web application:</p>
<ul>
<li><code>.class</code> or <code>.jar</code> files are modified</li>
<li><code>.properties</code> files are modified</li>
<li><code>.xml</code> files are modified</li>
</ul>
<h4>Patching the struts example application</h4>
<p>As mentioned at the beginning of these notes, the Struts Example Application
will not run under JRun without modification. The following changes will need
to be made:</p>
<ul>
<li>index.jsp, logon.jsp: Change <html:html locale="true"> to <br/><html:html
locale=<%= true %>></li>
<li>registration.jsp, subscription.jsp: Change all instances of filter="true" to
<br/>filter=<%= true %></li>

<p>Note that the instructions for Tomcat 4 will be different than those for Tomcat
3,
but the Tomcat 4.0 web connector is still under development. Versions of Tomcat
prior
to 3.2.1 are not recommend for use with Struts.</p>
<ul>
<li>These instructions assume you have successfully integrated Tomcat with Apache
according to the Tomcat documentation.</li>
<li>Copy "struts-documentation.war" and "struts-example.war" to your
$TOMCAT_HOME/webapps
directory</li>
<li>Restart Tomcat if it is already running</li>
<li>Tomcat will generate a file "$TOMCAT_HOME/conf/tomcat-apache.conf" that
will be used by Apache. This file is regenerated every time you start Tomcat,
so copy this file to a safe place (such as your Apache configuration directory;
on Unix systems this is usually <code>/usr/local/apache/conf</code>.</li>
<li>If you are running Tomcat 3.1, Tomcat will not have generated the entries
for your new applications. Add the following lines to the
<code>tomcat-apache.conf</code>
file that you have saved, replacing $TOMCAT_HOME with the path to your Tomcat
home directory:</li>
</ul>
<pre>
Alias /struts-documentation "$TOMCAT_HOME/webapps/struts-documentation
<Directory "$TOMCAT_HOME/webapps/struts-documentation>
Options Indexes FollowSymLinks
</Directory>
ApJServMount /struts-documentation/servlet /struts-documentation
<Location "/struts-documentation/WEB-INF/">

ApJServMount /struts-example/servlet /struts-example
<Location "/struts-example/WEB-INF/">
AllowOverride None
deny from all
</Location>
</pre>
<ul>
<li>The generated file above does not know anything
about extension mappings defined in a web.xml file, so the "*.do" URIs that
go to the controller servlet will not be recognized. To fix this, add the
following line to the saved version of "tomcat-apache.conf", after the
corresponding
line for the .jsp extension:<br/>
<code>AddHandler jserv-servlet .do</code></li>
<li>Ensure that the saved version of "tomcat-apache.conf" is referenced in your
Apache "httpd.conf" configuration file. A typical use would have the following
line at the bottom of "httpd.conf":<br/>
<code>Include /usr/local/apache/conf/tomcat-apache.conf</code></li>
<li>In order to recognize "index.jsp" as a default page for web applications,
search in your "httpd.conf" for a "DirectoryIndex" directive. If you have
one, add "index.jsp" to the end of the list, so that it might look like
this:<br/>
<code>DirectoryIndex index.html index.jsp</code><br/>
If you do not have such an entry, add one like this:<br/>
<code>DirectoryIndex index.jsp</code></li>
<li>Restart Apache to make it aware of the new applications. You should now
be able to access the applications from a browser like this:<br/>
<code>http://localhost/struts-documentation<br/>
http://localhost/struts-example</code></li>

<li>You need UBS version 7.2 to run war file applications. The UBS 7.2.2
evaluation
is located <a
href="http://www.bluestone.com/SaISAPI.dll/SaServletEngine.class/products/downloads.jsp">here</a>.
If you're using version 7.2.1, you need to download the WAR file patch, located
in the product enhancement section of Bluestone's website <a
href="http://www.bluestone.com/SaISAPI.dll/SaServletEngine.class/products/wfe.jsp">here</a>
</li>
<li> After installation of the correct version and/or patch of UBS 7.2, you
need to modify your apserver.txt file to point to the correct directory for
your war file applications. Look for the section that says something similar
to the following:<br />
<pre>
[SaServletEngine.class]
session_affinity=1
type=1
program=/SaServletEngine.class
file_path=f:\webapps
host=localhost:20000
</pre>
</li>
<li>Use the directory specified by the "file_path" variable, or modify it to
point to your own custom webapp directory. Copy the "struts-documention.war"
and "struts-example.war" files into that webapp directory, and start the UBS
(read documentation distributed with UBS for information on how to start it
if necessary). Your webapps are now accessible from the following URL:
<p align="center">
http://localhost/<PLUGIN>/SaServletEngine.class/struts-example/<br />
http://localhost/<PLUGIN>/SaServletEngine.class/struts-documentation/
</p>
</li>
<li> Note: "<PLUGIN>" represents the plugin you are using for your specific
webserver. For apache on Windows, it might be "cgi-bin/SaCGI.exe", for IIS
on Windows, it might be "scripts/SaCGI.exe" or "scripts/ISAPI.dll". Consult
the UBS documentation for more information. </li>

<li>Select a destination directory for the resulting web application, e.g.
<code>$WAS_HOME/hosts/default_host</code>. Press the Next button</li>
<li>Enter a "Web Application Web Path", e.g. struts-example, and a "Web
Application Name", e.g. struts-example. Press the Finish button.</li>
<li>You should, after a lengthy pause, get a message box with the text
Command "convert war file" completed successfully. Press Ok.</li>
<li>You now need to add jaxp.jar and a jaxp compatible parser, e.g.
parser.jar from JAXP 1.0.1 to the struts-example web application's
servlets directory, e.g.
<code>$WAS_HOME/AppServer/hosts/default_host/struts-example/servlets</code></li>
<li>At this point, if WAS 3.5.2 correctly implemented Servlet 2.2, all
would be fine. However, WAS 3.5.2 returns null for calls to
<code>ServletContext.getResource(String)</code> or
<code>ServletContext.getResourceAsStream(String)</code>. This manifests itself as
an
exception in the application server stdout log, e.g.
<code>default_server_stdout.log.</code></li>
<li>Warning: Don't be fooled by the fact that the web application starts
successfully from the Admin Console. It actually doesn't. The Admin
Console is lying. If you try to access the webapp
e.g. <code>http://localhost/struts-example/</code> it will fail.</li>
<li>At this point, you need to patch the Struts source. There are three
places <code>getResourceAsStream</code> is called:</li></ul>
<pre>
ResourceTag.doStartTag()
ActionServlet.initMapping()
PropertyMessageResources.loadLocale(String)
</pre>
<p>of these, <code>ActionServlet</code> is the most important.</p>
<ul><li>Change the source from</li></ul>
<pre>
// Acquire an input stream to our configuration resource
InputStream input = getServletContext().getResourceAsStream(config);
</pre>
<p>to</p>
<pre>
// Acquire an input stream to our configuration resource
InputStream input = new
java.io.FileInputStream(getServletContext().getRealPath(config));
</pre>
<ul><li> Make similar changes to the other classes if necessary.</li>
<li>Recompile ActionServlet and copy the <code>.class</code> file to <br/>
<code>$WAS_HOME/AppServer/hosts/default_host/struts-example/servlets/<br/>
org/apache/struts/action/ActionServlet.class</code></li>
<li>Another bug with WAS 3.5.2's classloaders is that Class.getResource()
wont load a resource from a jar, so you must copy<br/>
<code>$STRUTS_HOME/lib/struts-config_1_0.dtd</code> <br/>
to <br/>
<code>$WAS_HOME/AppServer/hosts/default_host/struts-example/servlets/org/apache/struts/resources/struts-config_1_0.dtd</code><br/>
or be connected to the Internet to fetch the dtd from the jakarta web site.</li>
<li>Start your webapp in the Admin Console</li>
<li>Test the example application by loading the following URL in your
browser of choice: <a
href="http://localhost/struts-example/">http://localhost/struts-example/"
>http://localhost/struts-example/</a></li>
