的Rails 3.1部署到JBoss 4.2.2

Question

當部署在JRuby在Rails 3.1的應用程序到JBoss，我有一個JNDI/JDBC連接問題。數據源存在，並且連接細

17:47:20,862 ERROR [STDERR] JNDI data source unavailable: javax.naming.NameNotFoundException: jdbc not bound; trying straight JDBC 
17:47:20,926 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/MyApp]] unable to create shared application instance

    from org/jruby/RubyKernel.java:2097:in `send' 

...

Caused by: org.jruby.exceptions.RaiseException: (ConnectionNotEstablished) jdbc adapter requires driver class and url 
17:47:23,010 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/MyApp]] Error: application initialization failed

的database.yml

############################################################### 
#################### PRODUCTION DATA ########################## 
############################################################### 

production: 
    adapter: jdbc 
    jndi: java:jdbc/my_datasource 
    driver: com.microsoft.sqlserver.jdbc.SQLServerDriver 

我檢查了兩個數據源和database.yml文件，但我有沒有線索爲什麼Rails沒有找到數據源。

更新

Warbler config 

# Disable Rake-environment-task framework detection by uncommenting/setting to false 
# Warbler.framework_detection = false 
# 
puts 'Compiling the asset manifests & other files in the pipeline to the disk' 
system('bundle exec rake RAILS_ENV=production RAILS_GROUPS=assets assets:precompile') 

# Warbler web application assembly configuration file 
Warbler::Config.new do |config| 

    # Application directories to be included in the webapp. 
    config.dirs = %w(app config lib log vendor tmp) 

    # Name of the archive (without the extension). Defaults to the basename 
    # of the project directory. 
    config.jar_name = "MyApp" 

    # Control the pool of Rails runtimes. Leaving unspecified means 
    # the pool will grow as needed to service requests. It is recommended 
    # that you fix these values when running a production server! 
    config.webxml.jruby.min.runtimes = 1 
    config.webxml.jruby.max.runtimes = 1 

    # JNDI data source name 
    # config.webxml.jndi = 'jdbc/rails' 
end 

DataSource配置

<datasources>  
<xa-datasource> 
    <jndi-name>jdbc/my_datasource</jndi-name> 
    <track-connection-by-tx/> 
    <isSameRM-override-value>false</isSameRM-override-value> 
    <xa-datasource-class>com.microsoft.sqlserver.jdbc.SQLServerXADataSource</xa-datasource-class> 
    <xa-datasource-property name="ServerName">myserver</xa-datasource-property> 
    <xa-datasource-property name="DatabaseName">mydb</xa-datasource-property> 
    <xa-datasource-property name="SelectMethod">cursor</xa-datasource-property> 
    <valid-connection-sql>SELECT 1</valid-connection-sql> 
    <user-name>user</user-name> 
    <password>pwd</password> 
     <metadata> 
     <type-mapping>MS SQLSERVER2000</type-mapping> 
     </metadata> 
    </xa-datasource> 
</datasources> 

Answer 1

部署.war文件啁啾了Rails的3.0.x的/ JBoss的5.1.0GA時，以下爲我的作品。

假設你已經成功地部署您的數據源與XML配置文件，它應該是這樣的：

<?xml version="1.0" encoding="UTF-8"?> 
<datasources> 
    <local-tx-datasource> 
     <jndi-name>my_datasource</jndi-name> 
     <connection-url>MYDATASOURCE_URL</connection-url> 
     <driver-class>your.Driver</driver-class> 
     ... define any other connection properties here ... 
    </local-tx-datasource> 
</datasources> 

你應該確認你的數據源確實是啓動並運行在JBoss的管理控制檯。

然後，假設你有你的config/warble.rb文件中的以下內容：

# JNDI data source name 
config.webxml.jndi = 'jdbc/my_datasource' 

# JBoss web-xmle file 
config.includes = 'jboss-web.xml' 

...並進一步假設你有一個直接配置jboss-web.xml文件中爲您的Rails項目文件夾下，有以下幾點：

<jboss-web> 
    <resource-ref> 
     <res-ref-name>jdbc/my_datasource</res-ref-name> 
     <jndi-name>java:/my_datasource</jndi-name> 
     <res-type>javax.sql.DataSource</res-type> 
    </resource-ref> 
</jboss-web> 

...那麼你應該確定，據我所知。

你能也許發表您的warble.rb，數據源XML配置文件，以及任何JBoss應用配置參數要設置？

[編輯] @Jared感謝您發佈您的配置文件。關閉我的頭頂，我可以爲您提供建議的下列位：

1. 糾正你database.yml到java:comp/env/jdbc/my_datasource的jndi值。
2. 定義config.webxml.jndi配置在warble.rb，並將其設置爲jdbc/my_datasource。
3. 此外，在您的warble.rb定義到一個新的JBoss web.xml文件的引用與config.includes = jboss-web.xml。
4. 創建這個新jboss-web.xml到JNDI名稱映射到JBoss資源引用名。根據你分享的文件，這將是我上面顯示的內容。你可以在你的Rails項目的根目錄下創建這個文件。

希望這會有所幫助！

Answer 2

我接受了buruzaemon的建議。結果發現我不小心將我的war文件複製到了/deploy/uuid-key-generator.sar目錄，我在jboss堆棧跟蹤顯示錯誤的jruby-jar版本後才發現這個。

爲了什麼它的價值，我學會了添加依賴

<depends>jboss.jca:service=DataSourceBinding,name=mydatasource</depends> 

給力的數據源文件的加載所有的應用程序之前，

/jboss-web.deployer/META-INF/jboss-service.xml
