DCH类与JavaMail错误 [英] DCH class error with JavaMail

问题描述

我正尝试使用Glassfish 3.1提供的jar文件在Java EE 6中使用JavaMail建立简单的日志记录测试。这个问题似乎有很多问题，但我还没有找到任何有帮助的答案。我的测试代码如下所示：

  import java.util.logging.Logger; 
 
 public class MyClass {
 private static final Logger LOGGER = Logger.getLogger（MyClass）; 
 
 public static void main（String [] args）{
 LOGGER.severe（This is a test）; 
 
 
  

我的logging.properties文件包含以下内容：

  com.sun.mail.util.logging.MailHandler.mail.smtp.host = {my mail hub FQDN} 
 com .sun.mail.util.logging.MailHandler.mail.smtp.port = 25 
 com.sun.mail.util.logging.MailHandler.mail.to = {me} 
 com.sun.mail .util.logging.MailHandler.mail.from = {support address} 
 com.sun.mail.util.logging.MailHandler.level =警告
 com.sun.mail.util.logging.MailHandler。 verify = local 
 com.sun.mail.util.logging.MailHandler.subject =应用程序错误
 com.sun.mail.util.logging.MailHandler.formatter = java.util.logging.SimpleFormatter 
  

我使用以下方式构建类：

  javac -cp $ AS_INSTALL / glassfish / modules / javax.mail.jar：$ AS_INSTALL / install / lib / external / jaxb / activation.jar :. MyClass.java 
  

然后我运行程序：

  java -cp $ AS_INSTALL / glassfish / modules / javax.mail.jar：$ AS_INSTALL / install / lib / external / jaxb / activation.jar :. -Djava.util.logging.config.file = logging.properties MyClass 
  

这会导致以下错误：

我已验证我的javax.mail.jar文件包含multipart处理程序：

  unzip  - l $ AS_INSTALL / glassfish / modules / javax.mail.jar | grep multipart 
 2617 01-14-2011 15:37 com / sun / mail / handlers / multipart_mixed.class 
  

我甚至在启用了激活调试的情况下运行该程序。这显示了以下相关部分：

  parse：multipart / * ;;的x java的内容处理器= com.sun.mail.handlers.multipart_mixed; x-java-fallback-entry = true 
类型：multipart / * 
命令：content-handler，Class：com.sun.mail.handlers.multipart_mixed

在这里？

谢谢，

虽然我很想知道更多关于这个问题背后的细节以及这个-Xbootclasspath选项为纠正问题所做的事情。如果我像这样运行我的类：

  java -Djava.util.logging.config.file = logging.properties -Xbootclasspath / p：/app/glassfish-3.1/glassfish/modules/javax.mail.jar MyClass 
  

它找到必要的课程和我收到我的电子邮件。现在我只需要弄清楚如何将这个配置转换成我的Glassfish服务器，并从这个简单的测试用例中尝试一个更真实的测试。

I'm attempting to set up a simple logging test with JavaMail in Java EE 6, using the jar files provided with Glassfish 3.1. There seems to be a wealth of questions out there on this subject, but I haven't found any answers that have helped yet. My test code looks like this:

import java.util.logging.Logger;

public class MyClass {
  private static final Logger LOGGER = Logger.getLogger("MyClass");

  public static void main(String[] args) {
    LOGGER.severe("This is a test");
  }
}

My logging.properties file contains this:

com.sun.mail.util.logging.MailHandler.mail.smtp.host={my mail hub FQDN}
com.sun.mail.util.logging.MailHandler.mail.smtp.port=25
com.sun.mail.util.logging.MailHandler.mail.to={me}
com.sun.mail.util.logging.MailHandler.mail.from={support address}
com.sun.mail.util.logging.MailHandler.level=WARNING
com.sun.mail.util.logging.MailHandler.verify=local
com.sun.mail.util.logging.MailHandler.subject=Application Error
com.sun.mail.util.logging.MailHandler.formatter=java.util.logging.SimpleFormatter

I build the class using:

javac -cp $AS_INSTALL/glassfish/modules/javax.mail.jar:$AS_INSTALL/install/lib/external/jaxb/activation.jar:. MyClass.java

Then I run the program using:

java -cp $AS_INSTALL/glassfish/modules/javax.mail.jar:$AS_INSTALL/install/lib/external/jaxb/activation.jar:. -Djava.util.logging.config.file=logging.properties MyClass

This results in the following error:

I've verified that my javax.mail.jar file contains the multipart handler:

unzip -l $AS_INSTALL/glassfish/modules/javax.mail.jar | grep multipart
     2617  01-14-2011 15:37   com/sun/mail/handlers/multipart_mixed.class

I've even run the program with the activation debugging enabled. This shows me the following related parts:

parse: multipart/*;;            x-java-content-handler=com.sun.mail.handlers.multipart_mixed; x-java-fallback-entry=true
  Type: multipart/*
    Command: content-handler, Class: com.sun.mail.handlers.multipart_mixed

MailcapCommandMap: createDataContentHandler for multipart/mixed
  search DB #1
  search DB #2
  search fallback DB #1
    got content-handler
      class com.sun.mail.handlers.multipart_mixed
Can't load DCH com.sun.mail.handlers.multipart_mixed; Exception: java.lang.ClassNotFoundException: com/sun/mail/handlers/multipart_mixed

I even get a duplicate of the above for type text/plain.

MailcapCommandMap: createDataContentHandler for text/plain
  search DB #1
    got content-handler
      class com.sun.mail.handlers.text_plain
Can't load DCH com.sun.mail.handlers.text_plain; Exception: java.lang.ClassNotFoundException: com/sun/mail/handlers/text_plain

What am I missing here?

Thanks, Steve

解决方案

I found the solution here:

http://blog.hpxn.net/2009/12/02/tomcat-java-6-and-javamail-cant-load-dch/

Though I would love to know more about the details behind why this is an issue and what this -Xbootclasspath option is doing to correct the problem. If I run my class like this:

java -Djava.util.logging.config.file=logging.properties -Xbootclasspath/p:/app/glassfish-3.1/glassfish/modules/javax.mail.jar MyClass

It finds the necessary classes and I get my email. Now I just have to figure out how to translate this configuration into my Glassfish server and try a more "real" test from this simple test case.
