Question

我们正在使用Webmethods 8.2，我们正在尝试从Linux机器上在SQL服务器上设置初始数据库。命令格式为

./dbConfigurator.sh -a create -d sqlserver -c storage -v latest -l jdbc:wm:sqlserver://<sqlserverip>:1433;databaseName=DBNAME" -u DBUSER -p Passwd -au ADMIN -ap Passwd

我们收到以下错误。有人可以破译我们的错误。我们感谢您提供的任何帮助。谢谢！

这是我的dbConfigurator.sh

Answer 1

当Java虚拟机无法在运行时找到编译时可用的特定类时，Java中出现

NoClassDefFoundError 。

在你的特殊情况下，JAVA找不到xml-apis.jar，像这样添加到setEnv.sh（找到路径并编辑）

CLASSPATH="$CLASSPATH:$DCI_HOME/../lib/xml-apis.jar"

Answer 2

java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

大概你的类路径错过了一些库org/w3c/dom/ElementTraversal。

Answer 3

根据一篇文章，他们有这个问题：

当我尝试使用版本2.0.2时遇到了问题，但发现我的时候   恢复到版本1.4.01，一切都恢复了。

如果你正在使用Maven：
<dependency> 
    <groupId>xml-apis</groupId>
    <artifactId>xml-apis</artifactId>
    <version>1.4.01</version> 
</dependency>

如果你没有，你也可以下载必要的库：

http://www.jarfinder.com/index.php/java/info/org.w3c.dom.ElementTraversal

参考1：Eclipse java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

参考2：http://www.coderanch.com/t/534171/XML/org-dom-ElementTraversal

Answer 4

首先，您需要确定您是在处理缺少的课程，还是某个课程缺失的课程：

http://javarevisited.blogspot.com/2011/06/noclassdeffounderror-exception-in.html

你有一个java.lang.ClassNotFoundException: org.w3c.dom.ElementTraversal，所以你正在处理一个缺失的类（一个更简单的场景）。您需要查看JAR通常包含的内容org.w3c.dom.ElementTraversal。我喜欢使用http://search.maven.org/，即使你没有使用Maven，也只是因为它是常用Java库的综合索引。要搜索课程，请使用fc:org.w3c.dom.ElementTraversal：

http://search.maven.org/#search%7Cga%7C1%7Cfc%3Aorg.w3c.dom.ElementTraversal

你会发现xml-apis的1.401版本。看起来搜索结果中的任何常见JAR都不在您的CLASSPATH中，除非它们位于$DCI_HOME/../lib/ext/sl53内部。您可以通过在#runJava echo $CLASSPATH之后添加一行来查看此问题，并查找上述搜索结果中列出的任何JAR。

如果它们不存在，您需要将JAR放在框中的某个位置并编辑setEnv.sh以包含它（除非您可以将它放在$DCI_HOME/../lib/ext/sl53中自动拾取它。）
