Hi Peter and Chris
I think that I should add something to the chris mail:
Mainly - as I know - there is two document for Installing exist with cocoon on tomcat one at Cocoon Wiki and One at eXist Wiki:
I prefer the document at eXist site, as Chris said, the document says that you should copy
* commons-pool-1.1.jar
*
xmlrpc-1.2-patched.jar
* xmldb.jar
* exist.jar
* exist-optional.jar
and optionaly
* castor-0.9.5-xml.jar
* commons-fileupload-1.0.jar
* isorelax.jar
* jgroups-all.jar
* xsdlib.jar
* msv.jar
from cocoon distribution to cocoon/WEB-INF/lib, (the exact list of required jars depends on your needs.) then you should remove
* xmldb-api-20030701.jar
* xmldb-common-20030701.jar
* xmldb-xupdate-20040205.jar
From cocoon/WEB-INF/lib.
Next, copy the central configuration file for exists from $EXIST_HOME/webapp/WEB-INF/conf.xml to cocoon/WEB-INF.
If you need to use the SOAP service,
you should also copy $EXIST_HOME/webapp/WEB-INF/server-config.wsdd to cocoon/WEB-INF.
In order to move the data in the eXist database, copy the contents of $EXIST_HOME/webapp/WEB-INF/data/ to cocoon/WEB-INF/data/.
Edit cocoon/WEB-INF/web.xml. At the top, before the Cocoon servlet is configured, add the following lines:
You can eliminate the servlets that you donât need them, You may skip the AxisServlet, AdminServlet, WebDAVServlet or RpcServlet (needed if you want to access the database instance from a remote client app), but you definitely need EXistServlet here
<!-- RpcServlet provides XML-RPC access to eXist -->
<servlet>
<servlet-name>org.exist.xmlrpc.RpcServlet</servlet-name>
<servlet-class>org.exist.xmlrpc.RpcServlet</servlet-class>
</servlet>
<servlet> <servlet-name>WebDAVServlet</servlet-name> <servlet-class>org.exist.http.servlets.WebDAVServlet</servlet-class>
<init-param> <param-name>authentication</param-name> <param-value>basic</param-value> </init-param> </servlet>
<!-- XQueryServlet generates HTML from
an XQuery file. --> <servlet> <servlet-name>XQueryServlet</servlet-name> <servlet-class>org.exist.http.servlets.XQueryServlet</servlet-class>
<init-param> <param-name>uri</param-name> <param-value>xmldb:exist:///db</param-value> </init-param>
<init-param> <param-name>form-encoding</param-name> <param-value>UTF-8</param-value> </init-param>
<init-param> <param-name>container-encoding</param-name> <param-value>UTF-8</param-value> </init-param>
<init-param>
<param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> </servlet>
<servlet> <servlet-name>EXistServlet</servlet-name> <servlet-class>org.exist.http.servlets.EXistServlet</servlet-class>
<!-- where to find eXist's configuration file relative to the basedir of the web-application. --> <init-param> <param-name>configuration</param-name> <param-value>conf.xml</param-value> </init-param>
<!-- eXist's home directory. All file names in the configuration file will be relative to this directory. --> <init-param> <param-name>basedir</param-name>
<param-value>WEB-INF/</param-value> </init-param>
<init-param> <param-name>start</param-name> <param-value>true</param-value> </init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<!-- configure the Axis servlets. Axis provides eXist's web-services via SOAP --> <servlet> <servlet-name>AxisServlet</servlet-name> <display-name>Apache-Axis Servlet</display-name> <servlet-class>org.apache.axis.transport.http.AxisServlet</servlet-class> </servlet>
<servlet> <servlet-name>AdminServlet</servlet-name> <display-name>Axis Admin Servlet</display-name> <servlet-class> org.apache.axis.transport.http.AdminServlet </servlet-class> <load-on-startup>100</load-on-startup> </servlet>
Next, you need to add url mappings for these servlets. At the bottom section of the file, again before the Cocoon mapping, add:
Again you can use only url mappings that you need
<!-- Define where the XMLRPC servlet listens -->
<servlet-mapping>
<servlet-name>org.exist.xmlrpc.RpcServlet</servlet-name>
<url-pattern>/xmlrpc</url-pattern>
</servlet-mapping>
<!-- eXist's DatabaseAdminServlet --> <servlet-mapping> <servlet-name>EXistServlet</servlet-name> <url-pattern>/servlet/*</url-pattern> </servlet-mapping>
<servlet-mapping> <servlet-name>WebDAVServlet</servlet-name> <url-pattern>/webdav/*</url-pattern> </servlet-mapping>
<!--
XQueryServlet --> <servlet-mapping> <servlet-name>XQueryServlet</servlet-name> <url-pattern>*.xql</url-pattern> </servlet-mapping>
<!-- The following servlet-mappings are for Axis (SOAP) --> <servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/axis-servlet/AxisServlet</url-pattern> </servlet-mapping>
<servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>*.jws</url-pattern> </servlet-mapping>
<servlet-mapping> <servlet-name>AxisServlet</servlet-name> <url-pattern>/services/*</url-pattern> </servlet-mapping>
<servlet-mapping> <servlet-name>AdminServlet</servlet-name> <url-pattern>/axis-servlet/AdminServlet</url-pattern> </servlet-mapping>
Then edit cocoon/WEB-INF/cocoon.xconf. Change the section that configures the xmldb pseudo protocol. Add the xmldb driver for eXist:
<!-- xmldb pseudo protocol -->
<component-instance
class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory"
name="xmldb">
<!-- Add here other XML:DB compliant databases' drivers -->
<driver class="org.exist.xmldb.DatabaseImpl" type="exist"/>
</component-instance>
This configuration works but from my experience it is better that you also replace org.apache.cocoon.components.source.impl.XMLDBSourceFactory with org.exist.cocoon.XMLDBSourceFactory, since it seems that
org.apache.cocoon.components.source.impl.XMLDBSourceFactory has some problems with unicode document, but org.exist.cocoon.XMLDBSourceFactory uses eXistâs xmldb source and is taylored to eXist and has no Unicode problem.
To use eXist's XSP logicsheet, edit the section on markup languages and include a reference to eXist's logicsheet at the
top:
<markup-languages>
<xsp-language logger="core.markup.xsp" name="xsp">
<parameter name="prefix" value="xsp"/>
<parameter name="uri" value="http://apache.org/xsp"/>
<!--+ | Properties for the java language +--> <target-language name="java"> <!-- Defines the XSP Core logicsheet for the Java language --> <parameter name="core-logicsheet" value="resource://org/apache/cocoon/components/language/markup/xsp/java/xsp.xsl"/>
<builtin-logicsheet> <parameter name="prefix" value="xdb"/> <parameter name="uri" value="http://exist-db.org/xmldb/1.0"/> <parameter name="href" value="resource://org/exist/xmldb.xsl"/> </builtin-logicsheet> ...
You should now be able to copy the contents of eXist's webapp directory ($EXIST_HOME/webapp) into a subdirectory of your Cocoon installation (e.g. cocoon/exist) and access eXist's main page and most examples. However, some examples won't work as they assume a fixed path /exist. The XQuery scripts need to be changed accordingly.
Also you can use XQuery Generator as Chris said.
