Orbeon 4.3在尝试访问MySQL时抛出ValidationException

在解决了最初的properties-local.xml问题之后，我转到了另一个问题。最初，我有一个命名上下文错误，我通过将

oxf.fr.persistence.provider.*.*

的值更改为

db

来解决该错误，该值与JBoss的资源定义相匹配

现在，当保存表单定义时，我会收到一个带有消息的错误对话框

There was an error communicating with the database. 
Please contact the application administrator.

当我检查server.log时，我注意到在输入新表单名称、标题和说明后单击continue之后出现了第一个异常

例外情况如下：

21:41:26,312 ERROR [org.orbeon.oxf.controller.PageFlowControllerProcessor] (http--127.0.0.1-8080-8) error caught {controller: "oxf:/apps/fr/page-flow.xml", method: "GET", path: "/fr/service/persistence/crud/orbeon/library/form/form.xhtml"}

我假设我的properties-local.xml需要一些工作。以下是内容：

<properties xmlns:xs="http://www.w3.org/2001/XMLSchema"
            xmlns:oxf="http://www.orbeon.com/oxf/processors">
  <property as="xs:string" name="oxf.fr.persistence.provider.*.*.*" value="db"/>
  <property as="xs:string" name="oxf.fr.persistence.mysql.datasource" value="db"/>
</properties>

我在没有第二个属性的情况下遇到了相同的错误。

除非您有一个名为

db

的提供程序，否则您的提供程序不能是

db

。但是看起来您想使用MySQL提供程序，所以您确实需要。因此您必须还原第一次更改。JBoss资源定义是否也需要命名为

MySQL

tation使用

db

我现在在MySQL中有表单定义和数据保存。现在，我要找出表单搜索失败的原因。数据源名称必须与

oxf.fr.persistence.MySQL.datasource

中指定的名称匹配。
