复制项目启动报错

标签：

今天复制一个新项目过程中犯了一个低级错误，记录下来，以示警戒：

复制了项目，复制了配置文件，修改了service name，启动tomcat，报错如下：

严重: Creation of the naming context failed: javax.naming.OperationNotSupportedException: Context is read only

调查才发现配置文件有错误：

原：

<Service name="test">

               maxThreads="2048" minSpareThreads="125" maxSpareThreads="475"

      <Resource name="web21service" auth="Container" type="javax.sql.DataSource" driverClassName="net.sourceforge.jtds.jdbc.Driver"

    </Context>
      </Host>
      </Engine>
 </Service>

复制新的：

<Service name="test2">
    <Connector port="1111"    maxHttpHeaderSize="8192"
               maxThreads="2048" minSpareThreads="125" maxSpareThreads="475"

        <Host name="localhost" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false">
    <Context path="" docBase="E:\workspace\test2\WebRoot" debug="5" reloadable="false" crossContext="true">
      <Resource name="web21gift" auth="Container" type="javax.sql.DataSource" driverClassName="net.sourceforge.jtds.jdbc.Driver" 
        url="jdbc:jtds:sqlserver://localhost:1433/test;useLOBs=false" username="sa" password="sa123" maxActive="200" maxIdle="10" maxWait="-1"/>
      <Resource name="web21service" auth="Container" type="javax.sql.DataSource" driverClassName="net.sourceforge.jtds.jdbc.Driver" 
        url="jdbc:jtds:sqlserver://localhost:1433/testService;useLOBs=false" username="sa" password="sa123" maxActive="20" maxIdle="10" maxWait="-1"/>
      
    </Context>
      </Host>
      </Engine>
 </Service>

错误就是只修改了server name 

<Service name="test2">

而没有 修改

Engine name

如下调整后问题解决，如果你也是这个错误，可以尝试看看是不是这种问题！

<Service name="test2">
    <Connector port="1111"    maxHttpHeaderSize="8192"
               maxThreads="2048" minSpareThreads="125" maxSpareThreads="475"
               enableLookups="false" redirectPort="8443" acceptCount="800"
               connectionTimeout="20000" disableUploadTimeout="true"  URIEncoding="utf-8"/>
    <Engine name="test2" defaultHost="localhost">
