Hi Chris,

I am having difficulties, can you please help

To start the server, add the following to the cocoon.xconf:

Well I have to admit, that I created my own Server component for starting the db itself inside cocoon … think you will have to have a look for code looking like:

BrokerPool.configure(“exist”, minBrokers, maxBrokers, config);

1. I assume that the XmlDbServerImpl above is your own component for starting the db inside cocoon - is that true?
2. What is home="C:/home/domains" for ?
3. What is suffix="data/xmldb" for ?

This is where initializing the BorkerPool for the instance is initialted. Couldn’t fin exactly which class is needed for this.

If you don’t manage to find it, I can send you mine, but that is made for initializing multiple Database Instances automatically (one per virtual hosts) but It would be suitable for a start J

4. I can't manage it, can you please send me yours

Thanks Peter

Hi All,

As I mentioned, my version only uses local access, so configuring all these additional servlets is not necessary and the additional jars aren’t needed.

One thing I remembered thou:I think the Driver automatically initializes the database if it can’t find an instance … had quite some problems with this.

Then it would be better to put the config-file in the place Abbas recommended. It will then find it automatically.

Regards, chris

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:

http://wiki.exist-db.org/space/CocoonInstall

http://wiki.apache.org/cocoon/EXistInCocoon?highlight=%28exist%29

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 donâ€™t 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



<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>

 <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>

 <init-param> <param-name>configuration</param-name> <param-value>conf.xml</param-value> </init-param>

 <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>

 <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



<servlet-mapping>

    <servlet-name>org.exist.xmlrpc.RpcServlet</servlet-name>

    <url-pattern>/xmlrpc</url-pattern>

</servlet-mapping>

 <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>

 <servlet-mapping> <servlet-name>XQueryServlet</servlet-name> <url-pattern>*.xql</url-pattern> </servlet-mapping>

 <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:



<component-instance

class="org.apache.cocoon.components.source.impl.XMLDBSourceFactory"

name="xmldb">



<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 eXistâ€™s 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"/>

 <target-language name="java">  <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.
