[opencms-dev] Re: Websphere & OpenCms & Struts: do you modified according to that paper?

[Georg Raffer]

Hello,

these are all things required for the Offline System. In online mode no
changes are required. The code modification described was already done
in OpenCms 6.02 Also the current OpenCms version uses JSTL 1.0


What you should do:

1 Check out the current OpenCms version and compile with java 1.4; for
jar creation disable compression.

2 enforce UTF-8 encoding: Server->Process Definition->JVM-> Generic JVM
arguments: -Dclient.encoding.override=UTF-8 (elese some problems wih
german Umlaute)

3 some cache settings have to be done in OpenCms: set cache property to
"bypass" for the following pages:
system/workplace/commons/property*.jsp, /editors/editor_main.jsp


For debugging I need more information:
Is the application installed as default application? I guess with
contextPath opencms?
What is a sample URL for OpenCms Index:

http://localhost:9080/opencms/opencms


In web.xml I am currently loading the action servlet before the opencms
servlet with load-on-startup 1:

<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/struts-config.xml</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>3</param-value>
</init-param>
<init-param>
<param-name>detail</param-name>
<param-value>3</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet>
<servlet-name>OpenCmsServlet</servlet-name>
<description>
The main servlet that handles all requests to the OpenCms VFS.
</description>
<servlet-class>org.opencms.main.OpenCmsServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
<servlet-name>OpenCmsServlet</servlet-name>
<url-pattern>/opencms/*</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>OpenCmsServletErrorHandler</servlet-name>
<url-pattern>/opencms-errorhandler/*</url-pattern>
</servlet-mapping>

If .do URLs are not handled by your Struts action servlet, you have an
error in web.xml Are there any important log entries in SystemOut.log /
SystemErr.log?

For improved debugging:

extend a new class my.domain.struts.action.ActionServlet from
org.apache.struts.action.ActionServlet

overwrite method

public void init() throws ServletException{
System.out.println("Before init action servlet .....");
super.init();
System.out.println("After init action servlet .....");
}

change

<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
to

<servlet-class>my.domain.struts.action.ActionServlet</servlet-class>

the initialized servlet must log to the SystemOut.log when the
application is started.


Moreover check your Websphere log file for:

Unable to initialize Struts ActionServlet due to an unexpected exception
or error thrown, so marking the servlet as unavailable. Most likely,
this is due to an incorrect or missing library dependency.

This is what struts writes to the error log when init failed. Maybe a
struts dependend library is missing on Websphere?

hope that helps ;)

bye, Georg
