我正在使用 pentaho 报表设计器生成报表。我的数据源是 mondrian olap cube。现在，我想将我的报表与 java 集成。我下载了 pentaho 报告 sdk 并修改了现有的示例 java 程序并提供了我的 .prpt 文件的路径。但我收到以下错误：
org.pentaho.reporting.libraries.resourceloader.ResourceCreationException: Unable to parse the document: ResourceKey{schema=org.pentaho.reporting.libraries.docbundle.bundleloader.ZipResourceBundleLoader, identifier=content.xml, factoryParameters={org.pentaho.reporting.libraries.resourceloader.FactoryParameterKey{name=repository}=org.pentaho.reporting.libraries.repository.zipreader.ZipReadRepository@ef028b, org.pentaho.reporting.libraries.resourceloader.FactoryParameterKey{name=repository-loader}=org.pentaho.reporting.libraries.docbundle.bundleloader.ZipResourceBundleLoader@19007a5}, parent=ResourceKey{schema=org.pentaho.reporting.libraries.resourceloader.loader.URLResourceLoader, identifier=file:/C:/Users/devang/workspace/samples/eclipse-bin/org/pentaho/reporting/engine/classic/samples/anor_admin.prpt, factoryParameters={}, parent=null}}
