我正在申请Solr.我正在使用apache-solr-solrj-1.4.0.jar.
当我尝试从中调用add(SolrInputDocument doc)时CommonsHttpSolrServer,我收到以下异常:
org.apache.solr.common.SolrException:org.apache.solr.client.solrj中org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:424)的内部服务器错误内部服务器错误. impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:243)位于org.apache.solr.client.solrj.SolrServer.add的org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:105) SolrServer.java:64)
有谁可以帮我解决这个问题？
以下是solrconfig.xml中的属性:
<lockType>native</lockType>
<unlockOnStartup>false</unlockOnStartup>
<reopenReaders>true</reopenReaders>
我在solr服务器日志中收到以下异常:

我需要一个Java代码来根据用户输入创建一个cron表达式.用户输入是时间,频率和执行次数.
我正在使用Quartz Scheduler,有15个工作.每个工作都有一个触发器.我想为每个触发器设置优先级.我可以将低优先级设置为10,将高优先级设置为1.但由于我有15个作业的15个触发器,因此每个触发器需要不同的优先级.例如,trigger1将具有优先级10,trigger2将具有优先级9.这样,我需要为两个触发器赋予相同的优先级.
因此,如果两个具有相同优先级的触发器将同时执行,那么哪个触发器将首先执行？
谁能告诉我如何为不同的触发器设置不同的优先级？
我正在使用iReport 3.7.4.我想将背景颜色设置为整个页面.我没有找到任何背景颜色的报告属性.任何人都可以帮助我吗？
我写了一个程序和一个工作.从工作我正在运行程序.以下是创建作业的脚本
DBMS_SCHEDULER.create_job (job_name => 'IBPROD2.RUN_FETCH_ACCT_ALERTS',
job_type => 'STORED_PROCEDURE',
job_action => 'FETCH_ACCT_ALERTS',
start_date => sysdate,
repeat_interval => 'FREQ=HOURLY;INTERVAL=2;',
enabled => TRUE,
auto_drop => FALSE
);
创建作业后,我正在运行以下命令来获取所有者IBPROD2的作业详细信息,其中我可以看到RUN_FETCH_ACCT_ALERTS作业的failure_count列值为1.手动运行时,程序FETCH_ACCT_ALERTS没有问题.
任何人都可以帮助我解决工作失败的原因吗？我错过了什么吗？
