本文解决了Struts2中常见的配置警告问题，当Tomcat控制台显示找不到指定操作的配置时，文章指导如何修改struts2表单中的action属性。
用惯了Struts1.1的朋友，在用struts2时可能会出现如下错误：

Tomcat 控制台打出如下警告：
WARN - No configuration found for the specified action: ‘xxxxx’in namespace: ‘/’. Form action defaulting to ‘action’ attribute’s literal value.

主要由于在写struts2表单时有给action指定全名，如:<s:form action=”xxxAction.do”…>,直接写成<s:form action=”xxxAction”…>即可,因为在struts.xml中struts.action.extension属性有指定啦。

分享一下，我这个错误，希望能帮到大家。 这个是空的空间命名错误，导致我查出的数据，在JSP页面显示不出来， 后面我看了一下方法，是我的SQL语句多了， if(goods.getGname()!=null&&goods.getGname().length()!=0){ sql=sql+" where g.gname like '%"+goods.getGname()+"%'"; }

Software Considerations – Configuration To configure the PA Manager: To create a PA Manager, call cpssDxChPacketAnalyzerManagerCreate, with the managerId parameter set (beginning with 1). To enable the PA Manager, call cpssDxChPacketAnalyzerManagerEnableSet, with the enable parameter set to GT_TRUE. Verify the XML file specifying the i-Debug configuration specific for the device is loaded under the appropriate location. See i-Debug XML Files for locations per platform. Set the device associated with the PA Manager, by calling with the CPSS device number, commonly 0. Should the XML configuration file be missing from the appropriate location, the API returns GT_FAIL. To create a Logical key, call cpssDxChPacketAnalyzerLogicalKeyCreate with: Key ID and name (keyAttrPtr is pointer to key name) A list of stages (CPSS_DXCH_PACKET_ANALYZER_LOOKUP_STAGES_ENT) and fields (CPSS_DXCH_PACKET_ANALYZER_FIELD_ENT) filtered by key NOTE: The key contains only the list of fields. The values determining the sampling/filtering is set by rules using that key - in each rule a list of respective field values. fieldModePtr key creation mode set to ALL / PARTIAL (see table Field Assignment Modes – CPSS_DXCH_PACKET_ANALYZER_FIELD_ASSIGNMENT_MODE_ENT) To create an action, call cpssDxChPacketAnalyzerActionCreate with: Action ID Action to perform samplingEnable set to GT_TRUE To apply the action to descriptors with field values other than those specified in the rule, set inverseEnable to GT_TRUE To create a group of rules, call cpssDxChPacketAnalyzerGroupCreate with its ID and name. To add a rule to a group, call cpssDxChPacketAnalyzerGroupRuleAdd with the following parameters setup: managerId – PA Manager ID keyId – Key ID containing list of fields for which the rule should specify the values, and list of stages in which to match/test these fields groupId – Group ID ruleId – The new rule ID ruleAttPtr – The new rule name numOfFields and fieldsValueArr – Respectively, number and list of specified field values matching the key fields actionId – An existing action ID to perform upon a found match To add keys, actions, rules, and groups, repeat steps 6. through 9.. To activate a group, call cpssDxChPacketAnalyzerGroupActivateEnableSet with the group ID and the enable parameter set to GT_TRUE. Run traffic. To disable a group, call cpssDxChPacketAnalyzerGroupActivateEnableSet with the group ID and the enable parameter set to GT_FALSE. To obtain the list of sampled stages, call cpssDxChPacketAnalyzerRuleMatchStagesGet. To display the sampled data – counters, field names, and field values, for a specific stage, call cpssDxChPacketAnalyzerStageMatchDataGet or cpssDxChPacketAnalyzerStageMatchDataAllFieldsGet. The first returns the values of fields included as input in the field list, and the latter - the values for all stage fields.
