Hi, I am trying to create a new rule, which can be defined in xml-rule file also. The rule is extension to the existing call-param-rule in which we can pass the constant parameters (mainly string constants) which is currently not possible with the call-param-rule. After googleing I found the steps to do it which are:
- Update the DTD. You should add an element type for your rule. The element should have an attribute corresponding to each of the rule's initialization parameters. - Define an ObjectCreationFactory - Extend DigesterRuleParser , and override the addRuleInstances() method to add the rules for parsing your new element. I did all the three steps but still I am not able to call the method with string constants which I am defining in the rule-xml. I am getting the values of parameter as null. Attachments: *digester-rules.dtd* (This is the updated dtd with the new element added as call-constant-param-rule. So step 1 is done. *UpdatedRuleParser.java* (This java file defines the ObjectCreationFactory (ConstantParamRuleFactory) and also extends the DigesterRuleParser. *_xelerator_config_rule.xml* (XML file which defines the digester rules). *_xelerator_config.xml *(XML document which needs to be parsed). *ConstantParamRule.java* (Extended rule file) What is it which i am missing or doing wrong. Thanks in advance. --wadi
