java - init() : Couldn't get lock for/var/lib/tomcat6/./tm.out 中的 Atomikos 错误

Question

我正在从事的项目需要帮助。它是一个使用 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，我无法再在我的 Ubuntu 12.10 64 位机器上部署我的 Web 服务器。

我得到的异常如下:

我的 JTA.properties 如下:

com.atomikos.icatch.console_file_name = tm.out
com.atomikos.icatch.log_base_name = tmlog

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

最后两个属性被评论为我为解决此错误所做的许多试验之一。

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>

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

请帮忙。 安德里亚

Answer 1

我遇到了同样的问题。似乎 tomcat 没有以正确的权限安装，或者我在 atomikos 配置中遗漏了一些东西。

在我的安装中，/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 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，但它被设置为“.”。 (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

如果您能找到更改“.”的位置到更好的东西，然后这将避免目录权限问题(如果你这样做，我建议在稍后阶段将其更改回来!)
