sparql - Fuseki 错误 500 : DatasetGraph. 删除(四)

转载作者：行者123 更新时间：2023-12-02 03:47:36

我已经设置了一个 Fuseki 端点，希望使用一些 SPARQL(选择和更新/删除查询)访问 Jena SDB 数据库(实际上是后端的 MySQL 数据库)。 SPARQL 选择查询工作得很好，但每当我尝试运行更新查询(例如插入或删除)时，我都会从 Fuseki 得到以下信息:

Error 500: DatasetGraph.delete(Quad)


Fuseki - version 0.2.6-SNAPSHOT (Build date: 2012-12-06T08:26:37-0500)

我已通过运行以下脚本启动了我的端点:

#!/bin/bash

 export FusekiInstallDir=/data/jena-fuseki-0.2.6-SNAPSHOT
 export FusekiPort=3030
 export FusekiJVMArgs="-cp ./fuseki-server.jar:lib/ReconnectingSDB-0.1-SNAPSHOT.jar:lib/jena-sdb-1.3.6-SNAPSHOT.jar:lib/mysql-connector-java-5.1.16-bin.jar:lib/jena-arq-2.9.5-SNAPSHOT.jar  -Xmx768M"
 export Date=`date +%Y-%m-%d`
 export FusekiLogFile=$FusekiInstallDir/FusekiLog-$Date.log
 export FusekiConfigFile=$FusekiInstallDir/fuseki.ttl
 export FusekiServiceName=/VIVO

 # Check to see if logfile exists
 if [ ! -f $FusekiLogFile ]; then
    touch $FusekiLogFile
 fi

 # Check to see if config file exists
 if [ ! -f $FusekiConfigFile ]; then
    echo “ERROR – Fuseki failed to start – no configuration file - $FusekiConfigFile” >> $FusekiLogFile
    exit 1
 fi

 # Execute Java calling the package for Fuseki
 java $FusekiJVMArgs org.apache.jena.fuseki.FusekiCmd --desc $FusekiConfigFile --update --port=$FusekiPort $FusekiServiceName >> $FusekiLogFile 2>&1 &

它访问以下配置文件(fuseki.ttl):

有人对可能导致此问题的原因有任何想法吗？下面是生成的 FusekiLog 文件(如果有帮助的话)。提前致谢!

最佳答案

你似乎正在运行

Fuseki - version 0.2.2-incubating-SNAPSHOT

尽管

export FusekiInstallDir=/data/jena-fuseki-0.2.4

这可能是一个已知错误，现已修复。可以升级到0.2.5吗？

配置说:

jumble:SDBConnect rdfs:subClassOf ja:RDFDataset .

但是

<#ufvivo_dataset_read> rdf:type      sdb:DatasetStore ;
    sdb:store <#VIVOStore>
   .
<#VIVOStore> rdf:type jumble:SDBConnect;

所以jumble:SDBConnect不是数据集(可能并不重要 - 代码遵循 <#VIVOStore> 链接

没有

sdb:DatasetStore  rdfs:subClassOf  ja:RDFDataset .

但是你的本地初始化类可能会在这里做一些事情。
