Hi,
I am using the commons-digester-1.4.1 and I am have used the digester
feeding it an xml rules file to parse my xml file and all works fine. Now I
am trying to define a method with parameters and I cannot seem to get the
syntax correct.
My xml file contains...
<ResourceParams name="jdbc/db2">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<!-- add remaining parameters here... -->
</ResourceParams>
The corresponding portion of my rules file contains...
<!-- Resource parameters are defined within the Context element and
associated a Resource -->
<pattern value="Context/ResourceParams">
<object-create-rule
classname="org.apache.catalina.deploy.ResourceParams"
attrname="resourcesParameters"/>
<!-- map the element's XML attributes to the bean properties -->
<set-properties-rule>
<alias attr-name="name" prop-name="name" />
</set-properties-rule>
<call-method-rule pattern="parameter"
methodname="addParameter"
paramcount="2">
<call-param-rule param-index="0"
attribute-name="name" />
<call-param-rule param-index="1" ^ - this is line 74, 45
attribute-name="value" />
</call-method-rule>
<!-- add the ResourceParams to the Context -->
<set-next-rule methodname="addResourceParams" />
</pattern>
</digester-rules>
When I attempt to parse the file I receive these error messages...

I looked at line 74, 45 and it "appears" to be correct?
Does anyone have any recommendations or could you please point me to the
rules file syntax documentation.
Thank you.
