线程“main”中的异常java.lang.NoClassDefFoundError: sdb/sdbconfig
我想将我的本体(在 Protege 中制作)导出到 MySQL 数据库中。我遵循这些说明: https://jena.apache.org/documentation/sdb/installation.html,和 https://jena.apache.org/documentation/sdb/commands.html。 当我使用命令“bin/sdbconfig --sdb=sdb.ttl --create”时,我收到此错误:
Exception in thread "main" java.lang.NoClassDefFoundError: sdb/sdbconfig
Caused by: java.lang.ClassNotFoundException: sdb.sdbconfig

Could not find the main class: sdb.sdbconfig. Program will exit.
我像这样设置环境变量:
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDBROOT="d:/My Dropbox/Diplomska/SDB-1.3.3"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_USER="root"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_PASSWORD=""
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_JDBC="d:/Fakultet/jars/mysql-connector-java-5.1.7-bin.jar"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export PATH=$SDBROOT/bin:$PATH
这是命令“bin/sdb_path”的输出:
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3

这是是“Store/sdb.ttl”文件: @

谁能告诉我我做错了什么?
I want to export my ontology (made in Protege) into MySQL database. I was following these instructions:
https://jena.apache.org/documentation/sdb/installation.html, and
https://jena.apache.org/documentation/sdb/commands.html.
And when I use the command "bin/sdbconfig --sdb=sdb.ttl --create", I get this error:
Exception in thread "main" java.lang.NoClassDefFoundError: sdb/sdbconfig
Caused by: java.lang.ClassNotFoundException: sdb.sdbconfig

at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:248)
Could not find the main class: sdb.sdbconfig. Program will exit.
I set the environment variables like this:
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDBROOT="d:/My Dropbox/Diplomska/SDB-1.3.3"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_USER="root"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_PASSWORD=""
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export SDB_JDBC="d:/Fakultet/jars/mysql-connector-java-5.1.7-bin.jar"
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ export PATH=$SDBROOT/bin:$PATH
This is the output of the command "bin/sdb_path":
Viktor@Pepe /cygdrive/d/My Dropbox/Diplomska/SDB-1.3.3
$ bin/sdb_path
d:/My Dropbox/Diplomska/SDB-1.3.3/lib/arq-2.8.7-tests.jar;d:/My Dropbox/Diplomsk

And this is the "Store/sdb.ttl" file:

这是一个非常基本的错误:sdbconfig 的类路径一定是错误的。不过我根本不懂windows和cygwin。
我的猜测是“My Dropbox”路径中的空格导致了此问题。您可以尝试将 sdb 移动到另一个目录吗?您还可以尝试
export SDBROOT="d:/My\ Dropbox/Diplomska/SDB-1.3.3"
。This is a really basic error: sdbconfig's classpath must be wrong. However I don't know windows and cygwin at all.
My guess is that the space in the path 'My Dropbox' is causing this. Could you try moving sdb to another directory? You could also try
export SDBROOT="d:/My\ Dropbox/Diplomska/SDB-1.3.3"
.
