Question

我已安装fuseki版本1.0.2，我可以使用 - ＆gt;

成功运行它

./ fuseki-server --update --loc = / home / mytdbs / tdb / ds

并在http://localhost:3030/sparql.tpl上查询。我有一个tdb，我想用java更新它。为此，我试图使用以下方式获取模型：

public static void main(String args[]){
    DatasetAccessor dataAccessor = datasetAccessorFactory.createHTTP("http://localhost:3030/ds/data");

    Model model = dataAccessor.getModel();
}

但是当我运行此命令时，我将得到以下异常：

java.lang.NoSuchFieldError：serviceContext at org.apache.jena.atlas.web.auth.ServiceAuthenticator.getServiceContextMap（ServiceAuthenticator.java:95）在 org.apache.jena.atlas.web.auth.ServiceAuthenticator.getCredentials（ServiceAuthenticator.java:101）在 org.apache.jena.atlas.web.auth.ServiceAuthenticator.getCredentials（ServiceAuthenticator.java:38）在 org.apache.jena.atlas.web.auth.AbstractScopedAuthenticator.findCredentials（AbstractScopedAuthenticator.java:107）在 org.apache.jena.atlas.web.auth.AbstractScopedAuthenticator.getUserName（AbstractScopedAuthenticator.java:50）在 org.apache.jena.atlas.web.auth.AbstractScopedAuthenticator.hasUserName（AbstractScopedAuthenticator.java:60）在 org.apache.jena.atlas.web.auth.AbstractCredentialsAuthenticator.apply（AbstractCredentialsAuthenticator.java:41）在 org.apache.jena.riot.web.HttpOp.applyAuthentication（HttpOp.java:1226）在org.apache.jena.riot.web.HttpOp.exec（HttpOp.java:1108）at at org.apache.jena.riot.web.HttpOp.execHttpGet（HttpOp.java:384）at org.apache.jena.riot.web.HttpOp.execHttpGet（HttpOp.java:353）at at org.apache.jena.web.DatasetGraphAccessorHTTP.doGet（DatasetGraphAccessorHTTP.java:134）在 org.apache.jena.web.DatasetGraphAccessorHTTP.httpGet（DatasetGraphAccessorHTTP.java:123）在 org.apache.jena.web.DatasetAdapter.getModel（DatasetAdapter.java:39）

我使用的是java 1.6和Jena 2.11.2。我对jena很新，所以我不确定其他哪些信息可能有用。非常感谢任何帮助/提示。

使用dataSetAccessor更新Fuseki
