無法在耳內訪問EJB jar

Question

我的耳結構如下：

XYZ.ear
    |
    |------------- lib
    |-------------META-INF
    |--------------firstEJB.jar
    |--------------app.war

當我嘗試部署XYZ.ear時，我無法訪問firstEJB.jar中的類。 我在嘗試部署時遇到了followint錯誤：

15:49:24,583 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-5) MSC000001: Failed to start service jboss.deployment.subunit."XYZ.ear"."app.war".POST_MODULE: org.jboss.msc.service.StartException in service jboss.deployment.subunit."XYZ.ear"."app.war".POST_MODULE: JBAS018733: Failed to process phase POST_MODULE of subdeployment "app.war" of deployment "XYZ.ear"

DeepInit類是firstEJB.jar中的一個類。

當我嘗試在lib目錄中添加firstEJB.jar時，它顯示了一些beanmanager相關的問題，因為它包含ejbs。 所以我經過這個鏈接嘗試將這個jar放在lib目錄之外：

https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly 。

我正在使用build.gradle來構建EAR.My build.gradle是：

buildscript {
    repositories {
        mavenCentral(); 
        maven {
            url "https://repository.jboss.org/nexus/content/repositories/releases/"
        }
    }

    configurations {
        compile
        testCompile
        testRuntime
        jacoco
    } 

    dependencies { 
        classpath 'org.ajoberstar:gradle-jacoco:0.3.0'
    }  
}

allprojects {
    group = 'com.sial.ecommerce'
    version = ''


    repositories {
        mavenCentral();
        maven {
            url "https://repository.jboss.org/nexus/content/repositories/releases/"
        }
    }

    apply plugin: 'java'
    apply plugin: 'jacoco';

    apply plugin: 'ear'

    dependencies {
        deploy project(path:':app', configuration: 'archives');
        deploy project(path:':firstEJB', configuration: 'archives');


    }

    ear {
        version = "";

        archiveName ="XYZ.ear";

        appDirName 'EarContent'

        duplicatesStrategy = DuplicatesStrategy.EXCLUDE;
        caseSensitive = true;

        rootSpec.exclude("**/activation-1.1.jar");
        rootSpec.exclude("**/asm*.jar");
        rootSpec.exclude("**/jboss-*.jar");
        rootSpec.exclude("**/org.jacoco*.jar");

    }
}

我在META-INF中的application.xml看起來像：

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/application_7.xsd" id="Application_ID" version="7">
  <display-name>ABC</display-name>
  <module>
    <web>
      <web-uri>app.war</web-uri>
      <context-root>app</context-root>
    </web>
  </module>
  <module>
      <ejb>myfirstEJB.jar</ejb>
    </module>
</application>

我注意到的另一個問題是，對於部署，服務器正在從以下位置搜索文件：

C：\\ Apps \\ wildfly8.0.0.Final \\ bin目錄

ERROR com.sial.ecommerce.core.init.DeepInit - C:\Apps\wildfly-8.0.0.Final\bin\src\test\resources\xml\con\con.json (The system cannot find the path specified)

DEEPInit類是myfirstEJB.jar中的一個類。

代替

C：\\ Apps \\ wildfly-8.0.0.Final \\ standalone \\ deploments目錄（我們的耳朵存在）。

有人可以幫助我構建和部署適當的耳朵，以便可以訪問firstEJB.jar中的類嗎？

Answer 1

嘗試將wildfly配置中EE子系統的“ear-subdeployments-isolated”屬性設置為false：

<subsystem xmlns="urn:jboss:domain:ee:1.0" >            
  <ear-subdeployments-isolated>false</ear-subdeployments-isolated>
</subsystem>

如果此設置設置為true（默認為afaik），那么您必須聲明從戰爭到jar的依賴關系：

https://docs.jboss.org/author/display/WFLY8/Class+Loading+in+WildFly

Answer 2

它看起來像類com.sial.ecommerce.core.init.DeepInit嘗試使用如下代碼讀取本地資源：

new File(".\src\test\resources\xml\con\con.json");

如果是，請將此代碼替換為：

com.sial.ecommerce.core.init.DeepInit.getResource("xml\con\con.json");
