DeploymentException&在WebLogic Admin Server 11g上找不到类 [英] DeploymentException & Class Not Found on WebLogic Admin Server 11g
问题描述
相关： 将外部属性文件加载到在WebLogic 11上运行的EJB 3应用程序
使用Oracle Enterprise Pack for Eclipse，我创建了一个企业项目，并命名为：
PropertiesDemoEAR
还创建了一个PropertiesDemoEARWeb模块，其中我将此代码
（在PropertiesDemoEARWeb / Java Resources / src / com.project.util中）：
package com.project.util;
public class PropertiesFileHandler extends ApplicationLifecycleListener {
private static final String FILE =C：/etc/error.properties;
public void preStart（ApplicationLifecycleEvent evt）{
System.out.println（\\\
\\\
\t\tInside preStart（）method\\\
\\\
）;
InputStream is =
evt.getApplicationContext（）。getAppClassLoader（）。getResourceAsStream（FILE）;
try {
属性convertedProps =
convertStreamToProperties（is）;
String userMissingError =
convertedProps.getProperty（USER_MISSING_ERROR）;
System.out.println（\\\
\\\
\t\tuserMissingError =
+ userMissingError +\\\
\\\
）;
} catch（Throwable e）{
e.printStackTrace（）;
}
}
public属性convertStreamToProperties（InputStream is）throws IOException {
System.out.println（\\\
\\\
\t\ tInside convertStreamToProperties（）method\\\
\\\
）;
属性props = new Properties（）;
if（is == null）{
throw new FileNotFoundException（property file+ FILE +'not found）;
} else {
props.load（is）;
返回道具;
}
}
}
Inside PropertiesDemoEAR /EarContent/META-INF/weblogic-application.xml
我以声明方式添加了以下监听器：
<？xml version =1.0encoding =UTF-8？>
< wls：weblogic-application
xmlns：wls =http://xmlns.oracle.com/weblogic/weblogic-application>
<！ - weblogic-version：10.3.5 - >

< wls：listener>
< wls：listener-class>
com.project.util.PropertiesFileHandler

< / wls：listener>
< / wls：weblogic-application>
右键单击PropertiesDemoEAR / Export / EAR文件/目的地：
C：\Oracle\Middleware\user_projects\domains\MyDomain\autodeploy
当我通过Eclipse运行WebLogic 11g时，我在控制台中收到此错误消息：

问题： p>
（1）我可能做错了什么？为什么找不到我的PropertiesFileHandler类？
（2）我的属性文件的位置（c：/etc/error.properties）是否适合或应该是在MyDomain目录中？
（3）是否有默认目录或只是简单的配置区域，WebLogic加载可在WebLogic中运行的任何应用程序可访问的属性文件？ p>
得到它的工作...问题是我将其设置为Web项目而不是Oracle中的Java EE实用程序项目企业版Eclipse。
作为一个Web项目，将.class文件放在WEB-INF / classes中而不是APP-INF。
另外，需要将error.properties放在我的实际域中。
C：\Oracle\Middleware\user_projects\domains \MyDomain
关于我自己的问题：
是否有默认目录或只是简单的配置区那个WebLogi c加载在WebLogic中运行的任何应用程序可访问的属性文件？
如果-Dweblogic.ext.dirs未设置，则默认为$ DOMAIN / lib; $ WL_HOME / common / lib / ext; $ WL_HOME / server / lib / ext
所以如果你在$ DOMAIN / lib中存储error.properties，它将在CLASSPATH和您应该可以使用getResourceAsStream（error.properties）加载它

Using Oracle Enterprise Pack for Eclipse, I created an Enterprise Project and named it:
PropertiesDemoEAR
Also created a PropertiesDemoEARWeb module in which I put this code
(inside PropertiesDemoEARWeb / Java Resources / src / com.project.util):
package com.project.util;
public class PropertiesFileHandler extends ApplicationLifecycleListener {
private static final String FILE = "C:/etc/error.properties";
public void preStart(ApplicationLifecycleEvent evt) {
System.out.println("\n\n\t\tInside preStart() method\n\n");
InputStream is =
evt.getApplicationContext().getAppClassLoader().getResourceAsStream(FILE);
try {
Properties convertedProps =
convertStreamToProperties(is);
String userMissingError =
convertedProps.getProperty("USER_MISSING_ERROR");
System.out.println("\n\n\t\tuserMissingError = "
+ userMissingError + "\n\n");
} catch (Throwable e) {
e.printStackTrace();
}
}
public Properties convertStreamToProperties(InputStream is) throws IOException {
System.out.println("\n\n\t\tInside convertStreamToProperties() method\n\n");
Properties props = new Properties();
if (is == null) {
throw new FileNotFoundException("property file '" + FILE + "' not found");
} else {
props.load(is);
return props;
}
}
}
Inside PropertiesDemoEAR/EarContent/META-INF/weblogic-application.xml
I added the following listener declaratively:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-application
xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-application" >
<!--weblogic-version:10.3.5-->
<wls:application-param>
<wls:param-name>webapp.encoding.default</wls:param-name>
<wls:param-value>UTF-8</wls:param-value>
</wls:application-param>
<wls:listener>
<wls:listener-class>
com.project.util.PropertiesFileHandler
</wls:listener-class>
</wls:listener>
</wls:weblogic-application>
Right clicked on the PropertiesDemoEAR / Export / EAR file / Destination:
C:\Oracle\Middleware\user_projects\domains\MyDomain\autodeploy
When I run WebLogic 11g through Eclipse, I get this error message in the console:
[ERROR] AdapterManager - ServletContainerAdapter manager not initialized correctly.

Question(s):
(1) What am I possibly doing wrong? Why can't it find my PropertiesFileHandler class?
(2) Is the location (c:/etc/error.properties) of my properties file suitable or should it be inside MyDomain directory?
(3) Is there a default directory or just simple configuration area that WebLogic loads properties files which are accessible to any application that runs in WebLogic?
Got it working... The issue was that I had it set up as Web Project rather than a Java EE Utility Project in Oracle Enterprise Edition for Eclipse.
As a web project, it was putting .class files inside WEB-INF/classes instead of APP-INF.
Also, needed to put error.properties inside my actual domain.
C:\Oracle\Middleware\user_projects\domains\MyDomain
In regards to my own question:
Is there a default directory or just simple configuration area that WebLogic loads properties files which are accessible to any application that runs in WebLogic?
If -Dweblogic.ext.dirs is not set, it defaults to $DOMAIN/lib;$WL_HOME/common/lib/ext;$WL_HOME/server/lib/ext
So if you store error.properties in $DOMAIN/lib it will be on the CLASSPATH and you should be able to load it using getResourceAsStream("error.properties")
