将UIMA与Solr集成时的例外情况

我正在尝试将UIMA与Solr集成。 我创建了pear文件(打包并安装) - opennlp.uima.OpenNlpTextAnalyzer_pear.xml 我正在使用openNLP-UIMA注释器进行文档分析。

pear(xml)文件位于我的系统路径:D:\ temp \ opennlp.uima.OpenNlpTextAnalyzer 上述路径具有以下目录结构: desc,lib,元数据,模型和梨文件本身。

梨文件的内容:

<?xml version="1.0" encoding="UTF-8"?> 
<pearSpecifier xmlns="http://uima.apache.org/resourceSpecifier">
    <pearPath>D:\temp\opennlp.uima.OpenNlpTextAnalyzer</pearPath>
</pearSpecifier>

我用CAS可视化调试器测试了梨文件,可以看到分析。

我提到https://cwiki.apache.org/confluence/display/solr/UIMA+Integration进行整合。

我指的是AE标签中梨文件的路径。

 <str name="analysisEngine">D/:temp/opennlp.uima.OpenNlpTextAnalyzer/opennlp.uima.OpenNlpTextAnalyzer_pear.xml</str>

但是当我尝试索引文档时,抛出以下异常:

我可以看到它没有读取pear(xml)文件,但是我无法找到它的原因。我是否错误地给了AE?请帮助我。

谢谢和问候,
