尝试使用 openjdk 6 安装 Emacs JDEE

我正在尝试让 JDE 自动完成 Java 代码。我正在运行 Ubuntu，并且安装了以下软件包：

openjdk-6-doc
openjdk-6-jdk
openjdk-6-jre
openjdk-6-jre-无头
openjdk-6-jre-lib
openjdk-6-source

我“从源代码”（不是从包管理器）安装了 JDEE。我在 .emacs 中包含了以下内容，正如此处另一个线程中所建议的那样（我检查了目录确实存在，并且似乎已经使用上面的包安装了正确的内容）：

;;JDEE
(add-to-list 'load-path "/usr/share/emacs/site-lisp/jdee-2.4.0.1/lisp")

(setq
 jde-bug-debugger-host-address "127.0.0.1"
 jde-bug-jre-home "/usr/lib/jvm/java-6-openjdk"
 jde-compile-option-debug (quote ("all" (t nil nil)))
 jde-debugger (quote ("jdb"))
 jde-global-classpath
   (quote ("." "/usr/share/java/" "/usr/lib/jvm/java-6-openjdk/"))
 jde-jdk-doc-url "/usr/share/doc/openjdk-6-doc/html/api/index.html"
 jde-jdk-registry (quote (("1.6.0" . "/usr/lib/jvm/java-6-openjdk")))
 jde-jdk (quote ("1.6.0"))
 jde-regexp-jar-file "/usr/share/java/regexp.jar"
 jde-sourcepath (quote (".")))

(require 'jde)

编辑 .java 文件时，Mx jde-compile 等功能可以工作很好，本地类出现在速度栏中，本地类有自动补全功能，但 : 例如，如果我输入以下内容：

import java.io.*;
import java.lang.*;
public class foo {
  private String bar;
  public static void main(String args[]) {
    System.o
  }
}

并且光标位于“System.o”，则不建议补全，即使我尝试 Mx语义-ia -完整符号菜单。（消息显示“无法找到“系统”的类型”）。

如果我输入“你好”。菜单给了我两个建议： main 或 bar

我注意到所有 java (io, lang...) 类文件都压缩在 /usr/lib/jvm/java-6-openjdk/src.zip 中并尝试解压缩它，在 emacs 中没有结果。

我缺少什么？

谢谢你！

I am trying to get JDE to auto-complete Java code. I'm running Ubuntu and I have the following packages installed:

openjdk-6-doc
openjdk-6-jdk
openjdk-6-jre
openjdk-6-jre-headless
openjdk-6-jre-lib
openjdk-6-source

I installed JDEE "from source" (not from the package manager).
I included the following in my .emacs, as suggested in another thread here (I checked the directories do exist and seem to have the right content installed with the packages above):

;;JDEE
(add-to-list 'load-path "/usr/share/emacs/site-lisp/jdee-2.4.0.1/lisp")

(setq
 jde-bug-debugger-host-address "127.0.0.1"
 jde-bug-jre-home "/usr/lib/jvm/java-6-openjdk"
 jde-compile-option-debug (quote ("all" (t nil nil)))
 jde-debugger (quote ("jdb"))
 jde-global-classpath
   (quote ("." "/usr/share/java/" "/usr/lib/jvm/java-6-openjdk/"))
 jde-jdk-doc-url "/usr/share/doc/openjdk-6-doc/html/api/index.html"
 jde-jdk-registry (quote (("1.6.0" . "/usr/lib/jvm/java-6-openjdk")))
 jde-jdk (quote ("1.6.0"))
 jde-regexp-jar-file "/usr/share/java/regexp.jar"
 jde-sourcepath (quote (".")))

(require 'jde)

When editing a .java file, functions like M-x jde-compile work fine, local classes appear in speedbar, there is autocompletion for local classes BUT not for : for example if I type the following:

import java.io.*;
import java.lang.*;
public class foo {
  private String bar;
  public static void main(String args[]) {
    System.o
  }
}

And the cursor is at 'System.o', no completion is suggested, even when I try M-x semantic-ia-complete-symbol-menu. (The message says "Cannot find types for "System"").

If I type 'hello.' the menu gives me two sugestions: main or bar

I noticed that all the java (io, lang...) class files are compressed in /usr/lib/jvm/java-6-openjdk/src.zip and tried to uncompress it, with no results in emacs.

What am I missing?

Thank you!
