Question

我需要帮助处理我正在进行的项目。它是使用Java spring构建的Web服务器。我使用Tomcat 6作为Web服务器。我从MyEclipse For Spring切换到Eclipse EE，我无法在我的Ubuntu 12.10 64位机器上部署我的Web服务器。

我得到的例外情况如下：

我的JTA.properties如下：

com.atomikos.icatch.service=com.atomikos.icatch.standalone.UserTransactionServiceFactory
com.atomikos.icatch.console_file_name = tm.out
com.atomikos.icatch.log_base_name = tmlog
com.atomikos.icatch.tm_unique_name = myeclipseforspring
com.atomikos.icatch.serial_jta_transactions=false

#com.atomikos.icatch.output_dir=/home/atomikos-sw-tmp/
#com.atomikos.icatch.log_base_dir=/home/atomikos-sw-tmp/

最后两个属性被评为我为解决此错误而进行的众多试验之一。

我的servlet-dao-context.xml是：

<!-- Using Atomikos Transaction Manager -->
    <bean class="com.atomikos.icatch.jta.UserTransactionManager" destroy-method="close" id="atomikosTransactionManager" init-method="init">
        <property name="forceShutdown" value="true"/>
        <property name="startupTransactionService" value="true"/>
        <property name="transactionTimeout" value="60"/>
    </bean>
    <bean class="com.atomikos.icatch.jta.UserTransactionImp" id="atomikosUserTransaction"/>
    <!-- Configure the Spring framework to use JTA transactions from Atomikos -->
    <bean class="org.springframework.transaction.jta.JtaTransactionManager" id="transactionManager">
        <property name="transactionManager" ref="atomikosTransactionManager"/>
        <property name="userTransaction" ref="atomikosUserTransaction"/>
        <property name="transactionSynchronizationName" value="SYNCHRONIZATION_ON_ACTUAL_TRANSACTION"/>
    </bean>

我不知道如何使这项工作。我不明白为什么它在路径/var/lib/tomcat6/./tm.out中搜索文件tm.out。 “/./”代表什么？

请帮忙。安德烈

Answer 1

我遇到了同样的问题。似乎tomcat没有使用正确的权限进行安装，或者我在atomikos配置中遗漏了一些内容。

在我的安装上，/ var / lib / tomcat6被许可为'root'，而所有其他子目录都是'tomcat6'。由于tomcat以用户tomcat6的身份运行，因此无法创建文件。

我将/ var / lib / tomcat6目录的所有者更改为tomcat6，一切正常，没有问题。我假设atomikos期望给它一个tomcat目录的子目录，但这被设置为'。' （这意味着当前目录本身或当前目录，如果它构成路径的一部分，如'..'表示父目录）。因此它实际上是$ TOMCAT_HOME / {atomikos-dir} /tm.out

如果你能找到改变的地方'。'为了更好的东西，那么这将避免目录权限问题（如果你这样做，我会建议在以后更改它！）

init（）中的Atomikos错误：无法获取/var/lib/tomcat6/./tm.out的锁定
