我有两个Pentaho插件。在GWT中制作的一个在5.0-5.2中工作并返回我需要的所有尺寸。现在我需要重构而不用gwt。我将连接代码放在我的新REST服务中，代码在pentaho 5.0中运行良好但在5.2中失败。我相信问题不在代码中，但我试图理解为什么如果在gwt服务中运行良好，它会失败。
MondrianProperties pr = MondrianProperties.instance();
// Customize Mondrian to get connection
pr.setProperty("mondrian.rolap.ignoreInvalidMembers", "true");
pr.setProperty("mondrian.rolap.ignoreInvalidMembersDuringQuery", "true");
pr.DataSourceResolverClass.setString("org.pentaho.platform.web.servlet.PentahoDataSourceResolver");
Properties props = MondrianPropertyLoader.loadProperties();
for(String property: props.stringPropertyNames()) {
pr.setProperty(property, props.getProperty(property));
}
url = "jdbc:mondrian:Catalog=" + catalogDefinition + ";Datasource=" + dataSource; // + props;
Class.forName("mondrian.olap4j.MondrianOlap4jDriver");
// In Pentaho 5.2 RESTService fail
// ---------------------------------
OlapConnection connection = (OlapConnection) DriverManager.getConnection(url, "", "");
// ---------------------------------
final OlapWrapper wrapper = connection;
OlapConnection tmpolapConnectionStx = (OlapConnection) wrapper.unwrap(OlapConnection.class);
olapConnection = tmpolapConnectionStx;
//Roles stuff
setRoles(connection.getAvailableRoleNames());
connection = null;
Class.forName("mondrian.olap4j.MondrianOlap4jDriver");
url += ";Role=" + getStringRoles();
connection = (OlapConnection) DriverManager.getConnection(url, "", "");
final OlapWrapper wrapper2 = connection;
tmpolapConnectionStx = null;
tmpolapConnectionStx = (OlapConnection) wrapper2.unwrap(OlapConnection.class);
if (tmpolapConnectionStx == null) {
throw new Exception("Connection is null");
}
olapConnection = tmpolapConnectionStx;
this.initialized = true;
以前的代码对于两者都是相同的，但Pentaho 5.2中的新服务就行了
OlapConnection connection =（OlapConnection）DriverManager.getConnection ...
失败并使用此网址抛出以下异常

两个插件都是相同的pentaho并且具有相同的mondrian属性，所以我不明白它为什么会发生。
答案 0 :(得分：1)
最近我查看了我的旧代码并删除了plugin.spring.xml中我不需要的一些代码，我的插件工作没有错误。
产生问题的行是以下
<context:property-placeholder location="config/jdbc.properties"/>
<!-- import rest="lib/hibernate.cfg.xml"/ -->
<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close"
p:driverClassName="${jdbc.driverClassName}"
p:url="${jdbc.url}"
p:username="${jdbc.username}"
p:password="${jdbc.password}"
p:maxActive="${dbcp.maxActive}"
p:maxIdle="${dbcp.maxIdle}"
p:maxWait="${dbcp.maxWait}"
/>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean"
p:dataSource-ref="dataSource"
p:configurationClass="org.hibernate.cfg.AnnotationConfiguration"
p:packagesToScan="com.stratebi.stx.console.model">
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.show_sql">${hibernate.show_sql}</prop>
<prop key="hibernate.format_sql">${hibernate.format_sql}</prop>
<prop key="hibernate.hbm2ddl.auto">${schema.generation}</prop>
<prop key="hibernate.generate_statistics">${hibernate.generate_statistics}</prop>
<prop key="hibernate.connection.url">${jdbc.url}</prop>
<prop key="hibernate.connection.driver_class">${jdbc.driverClassName}</prop>
<prop key="hibernate.connection.username">${jdbc.username}</prop>
<prop key="hibernate.connection.password">${jdbc.password}</prop>
</props>
</property>
<!--property name="annotatedPackages" value="com.stratebi.stx.console" />
<property name="configLocation" value="config/hibernate.cfg.xml" / -->
<property name="eventListeners">
<map>
<entry key="merge">
<bean class="org.springframework.orm.hibernate3.support.IdTransferringMergeEventListener"/>
</entry>
</map>
</property>
<property name="annotatedClasses">
<list>
</list>
</property>
</bean>
<tx:annotation-driven transaction-manager="txnManager"/>
<!-- Hibernate transaction manager -->
<bean id="txnManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager"
p:sessionFactory-ref="sessionFactory"/>
但是我认为真正的问题是由事务管理器或者hibernate生成的，它与Pentaho自己的库发生了冲突，我需要稍后再查看，但是现在错误消失了。
答案 1 :(得分：0)
您正在私人＆＃39;内创建自己的蒙德里安实例。 classloader空间。似乎它无法正确解析JNDI连接。
尝试更简单的方法并查看Pentaho平台中的IOlapService。
