[rules-users] Strange error using Drools + Spring + DecisionTable

Hi, When I try to instantiate an Excel Decision Table using Drools + Spring (kresource), I get this error : REMARK: the file is the same as we have in Drools Unit Test (decision-table) Error : Caused by: java.lang.IllegalArgumentException: Your InputStream was neither an OLE2 stream, nor an OOXML stream at org.apache.poi.ss.usermodel.WorkbookFactory.create(WorkbookFactory.java:75) at org.drools.decisiontable.parser.xls.ExcelParser.parseFile(ExcelParser.java:75) at org.drools.decisiontable.SpreadsheetCompiler.compile(SpreadsheetCompiler.java:93) at org.drools.decisiontable.SpreadsheetCompiler.compile(SpreadsheetCompiler.java:72) at org.drools.decisiontable.DecisionTableProviderImpl.compileStream(DecisionTableProviderImpl.java:37) at org.drools.decisiontable.DecisionTableProviderImpl.loadFromInputStream(DecisionTableProviderImpl.java:20) at org.drools.compiler.compiler.DecisionTableFactory.loadFromInputStream(DecisionTableFactory.java:15) at org.drools.compiler.compiler.PackageBuilder.decisionTableToPackageDescr(PackageBuilder.java:460) at org.drools.compiler.compiler.PackageBuilder.addPackageFromDecisionTable(PackageBuilder.java:454) at org.drools.compiler.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:684) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:51) at org.drools.compiler.builder.impl.KnowledgeBuilderImpl.add(KnowledgeBuilderImpl.java:40) at org.drools.container.spring.beans.KnowledgeBaseBeanFactory.afterPropertiesSet(KnowledgeBaseBeanFactory.java:110) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1477) at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1417) Config : <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:drools="http://drools.org/schema/drools-spring" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring.xsd"> <drools:grid-node id="node1"/> <drools:kbase id="kbase1" node="node1"> <drools:configuration> <drools:mbeans enabled="true"/> </drools:configuration> <drools:resources> <drools:resource type="DTABLE" source="classpath:data/IntegrationExampleTest.xls"/> </drools:resources> </drools:kbase> <drools:ksession id="ksession1" type="stateless" name="ksession1" kbase="kbase1" node="node1"/> </beans> Regards, -- Charles Moulliard Apache Committer / Sr. Enterprise Architect (RedHat) Twitter : @cmoulliard | Blog : http://cmoulliard.blogspot.com
