Question

我在Netbeans中实现了一个基于SOAP的Web服务。我在服务器端遇到了一些问题，它给了我错误500，内部错误，因为我无法自动调试它告诉我检查日志但是我的catalina.out充满了这段代码：

     Aug 20, 2011 11:01:32 PM org.apache.catalina.realm.CombinedRealm startInternal

基本上它充满了相同的代码，只有当我启动或关闭我的Tomcat没有任何有用的东西时才显示出来，这可能导致我为什么它给我错误500.有人请告诉我可能导致什么

      org.apache.catalina.realm.CombinedRealm startInterna

提前多多谢谢。

这是server.xml的一部分，我根据我的数据库密码等更改了它的值。

                 <GlobalNamingResources>
        <!-- Editable user database that can also be used by
         UserDatabaseRealm to authenticate users
        -->
        <Resource name="NeuroJDBC" auth="Container"
              type="javax.sql.Datasource"
            driverClassName="com.mysql.jdbc.Driver"
            password="alpbra"
            maxIdle="2"
            maxWait="5000"
            removeAbandoned="true"
            removedTimeout="60"
            username="root"
            url="jdbc:mysql://localhost:3306/NeuroDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
      </GlobalNamingResources>

Answer 1

在我的情况下，Tomcat无法重新启动并引发了相同的消息。但是问题出在POM.xml中，我提到JAVA版本是1.8，并且代码是在JDK 1.8上编译的。但是在服务器上安装的JDK是1.7。更改版本并创建在JDK1.7上编译的war文件解决了我的问题。希望这可以帮助某人

<properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.7</java.version>
</properties>

Answer 2

如果您没有使用tomcat 5，请参阅此链接http://tomcat.apache.org/tomcat-5.5-doc/config/realm.html（或tomcat版本的领域文档）。从堆栈跟踪看来，你有一个围绕领域的配置问题。

stacktrace中的错误：在UserDatabase

下找不到UserDatabase组件

在$ CATALINA_HOME / conf / server.xml中，您可以尝试更改

<Resource name="NeuroJDBC" auth="Container"

到

<Resource name="UserDatabase" auth="Container"

Catalina.out中的错误“org.apache.catalina.realm.CombinedRealm startInterna”
