和BTW，這裏是我的Solr的Web Solr的-spring.xml

<beans> 
    <bean id="indexSearcher" class="com.liferay.portal.search.solr.SolrIndexSearcherImpl"> 
    <property name="serverURL" value="http://localhost:8983/solr/select" /> 
    </bean> 
    <bean id="indexWriter" class="com.liferay.portal.search.solr.SolrIndexWriterImpl"> 
    <property name="serverURL" value="http://localhost:8983/solr/update" /> 
    </bean> 
    <bean id="searchEngine" class="com.liferay.portal.search.solr.SolrSearchEngineImpl"> 
    <property name="name" value="Solr" /> 
    <property name="searcher" ref="indexSearcher" /> 
    <property name="writer" ref="indexWriter" /> 
    <property name="indexReadOnly" value="false" /> 
    </bean> 

<bean id="searchEngineUtil" class="com.liferay.portal.search.solr.SolrSearchEngineUtil" lazy-init="false"> 
    <constructor-arg ref="searchEngine" /> 
    <constructor-arg ref="searchReaderMessageListener" /> 
    <constructor-arg ref="searchWriterMessageListener" /> 
    </bean>

，什麼會schema.xml中會在這種情況下looklike

他HttpUtils類竟是改變，因此，要解決這個一個是與我們修改

似乎你的應用服務器中必須有多個portal-kernel.jar文件。

此jar不能至少包含在應用服務器門戶應用和插件，或者如果在如Tomcat servlet容器運行全局類路徑耳的範圍內進行復制。

沒有，這個問題是不是在罐子裏的一個，以取代原來的內核類適合的要求，我搜索了tomcat目錄並發現的門戶kernel.jar但問題只有當我安裝插件的Solr的形勢發生如下只有一個副本：我的Solr服務器並在端口8983和Liferay的服務器在8080上運行，當我安裝插件的Solr我配置更新和選擇solr的URL，然後我得到了上面拋出的異常 – 2010-03-22 19:31:23
