Configuring Tyrex in tomcat 4.1.2

[Ian Venter (IT_SBS)]

Hi

 

I am trying to configure tyrex to work with tomcat to get transaction
management working.

 

I've downloaded the six jar files as per the documentation and placed them
in the $TOMCAT_HOME$/common/lib

 

I have created myself a domain-config.xml file which looks as follows:

 

<domain>

  <name>default</name>

  <!-- Limit to 50 concurrent transactions -->

  <maximum>50</maximum>

  <!-- Default transaction timeout: 2 minutes -->

  <timeout>120</timeout>

            <resources>

    <!-- Specification for data source myDataSource -->

        <dataSource>

      <name>myDatasource</name>

      <jar>C:\Program Files\Apache Group\Tomcat
4.1\webapps\NDEIS\WEB-INF\lib\oracle.jar</jar>

      <class>oracle.jdbc.xa.OracleXADataSource</class>

      <config>

        <user>someusername</user>

        <password>somepassword</password>

        <serverName>labdbsdev</serverName>

        <port>1521</port>

        <database>ndeis</database>

      </config>

    </dataSource>

      <limits>

        <!-- Start with 5 connections, never go below 5,

             and never go above 50 -->

        <maximum>50</maximum>

        <minimum>5</minimum>

        <initial>5</initial>

        <!-- Discard connections idle for 5 minutes -->

        <maxRetain>300</maxRetain>

        <!-- If maximum reached, block for 10 seconds -->

        <timeout>10</timeout>

      </limits>

 

  </resources>

</domain>

 

I also have modified my server.xml to include the following code snippet

 

      <Context path="/NDEIS" docBase="NDEIS" debug="0"

                 reloadable="true" crossContext="true">

 

                            <!-- Entry for tyrex -->

                            <Environment name="tyrexDomainConfig"
type="java.lang.String" value="domain-config.xml"/>

                                    <Environment name="tyrexDomainName"
type="java.lang.String" value="default"/>

 

                                    <Resource name="myDataSource"
auth="Container" type="tyrex.resource.Resource"/>

                                    <ResourceParams name="myDataSource">

                                      <parameter>

                                        <name>name</name>

                                        <value>myDataSource</name>

                                      </parameter>

                                    </ResourceParams>

        </Context>

 

After making these changes tomcat refuses to startup. 

                                    <Resource name="myDataSource"
auth="Container" type="tyrex.resource.Resource"/>

                                    <ResourceParams name="myDataSource">

                                      <parameter>

                                        <name>name</name>

                                        <value>myDataSource</name>

                                      </parameter>

                                    </ResourceParams>

I've noticed that when I remove the above bold section from the
<context></context> element then tomcat starts up. So the problem most
probably lies with the domain-config.xml but I cant figure it out. 

 

Can anybody please help.
