在运行并为WebSphere开发的Tomcat 7中启动Web应用程序

将WebSphere App移植到运行Java 6的TOMCAT 7

我们只是想看看是否可以做到这一点。我们不使用EJB。该应用程序已有10年历史,并连接到Oracle数据库(11g)。我们一直在添加并修改它,因为它正在大量使用。它一直在Websphere 6.1下运行,并且有几个JAX-RPC Web服务。我让它在WebSphere 8.5上运行但成本不变,我们决定尝试使用TOMCAT 7和JUNO。

我没有与Tomcat广泛合作,因为这是一家IBM商店。更多的应用程序似乎正在使用Tomcat,所以我更愿意学习。我安装了Eclipse - Juno,在我的工作区中,我在创建一个新的动态Web项目后引入了应用程序文件。我们的应用程序部署为EAR文件,但在这里我将它部署为WAR文件。构建时出现了许多警告和错误。

我安装了TOMCAT并使用我在网上找到的部署并正确运行的小型webServices应用程序教程对其进行了测试。我把服务器带进了我的项目 通过查找jar文件并将其移入WEB / lib或Tomcat lib目录,可以快速解决大多数编译错误。例如,ojdbc6.jar文件位于Tomcat lib中。

我现在不打算进行最佳配置,我们只是想看看能否让它发挥作用。这就是为什么我将com.ibm.ws.runtime.jar移动到应用程序的WEB-INF库中以清除大多数编译错误。我们绝对不希望使用它,但如果我们让它运行,我们将进一步尝试删除它并重新生成Web服务。我很快就得到了一个干净的编译。

我确实让Data Source Explorer将数据库连接识别为一边,但我在启动应用程序时遇到了麻烦。这就是我所做的 在我的应用程序web.xml文件的顶部,我添加了一个Oracle数据库条目,如下所示:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
    xmlns="http://java.sun.com/xml/ns/javaee" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
    <display-name>SupplierNetRelease</display-name>
    <resource-ref>
        <description>SupplierNet Oracle Database</description>
        <res-ref-name>jdbc/SupplierNetDataSource</res-ref-name>
        <res-type>javax.sql.DataSource</res-type>
        <res-auth>Container</res-auth>
    </resource-ref>
    <servlet>
        <display-name>MsgLogin</display-name>
        <servlet-name>MsgLogin</servlet-name>
        <servlet-class>com.alstom.power.suppliernet.servlets.MsgLogin</servlet-class>
    </servlet>.........

我想知道我是否应该重新生成这个jsut移植到应用程序的文件?它显示了web-app version =“2.5”,尽管Tomcat 7可以与3.0一起工作。我相信。

在Tomcat的context.xml文件中,我添加了:

...<Resource name="SupplierNetDataSource"
        auth="Container"
        type="javax.sql.DataSource"
        username="xxxxxx"
        password="xxxxxx"
        driverClassName="oracle.jdbc.OracleDriver"
        url="jdbc:oracle:thin:@localhost:1521:supnjttx"
        maxActive="10"
        maxIdle="4"/>

</Context>

到目前为止,我没有对server.xml文件进行任何更改。在tomcat-Users.xml中,我将自己添加为manager-gui。我们不希望任何其他应用程序在服务器上运行,但我们的应用程序。 我不知道是否要向GlobalNamingResources部分添加任何东西是值得尝试的,尽管有些文件似乎暗示了这一点。

当我第一次启动服务器的时候,我得到了一个xml解析错误,我没有追踪到这个错误,但现在的情况是错误没有出现。 我现在得到一个'启动组件失败'(见下文)'引起:java.lang.IllegalArgumentException:无效的服务/ Au 在servlet映射中的thorizer'等等。

如果有人能提出建议我会很感激。如果你想看到更多,请让我清楚地知道你想看到的是什么。我们希望它在没有上下文的情况下运行,但也就是说 在这一点上是次要的。如果我错过了一些明显的东西,我道歉。提前谢谢。

根据规范,像这样的网址格式必须以/开头。将您的web.xml更改为:

<url-pattern>/services/Authorizer</url-pattern>

答案 1 :(得分:0)

  

警告:找不到与“上下文/资源”匹配的规则。

这是一个严重的问题!请注意,context.xml的内容区分大小写
