When things in your life seem almost too much to handle, when 24 hours in a
day are not enough, remember the mayonnaise jar and the 2 cups
of coffee.
A professor stood before his philosophy class and had some items in front of
him. When the class began, he wordlessly picked up a very large and empty
mayonnaise jar and proceeded to fill it with golf balls. He then asked the
students if the jar was full. They agreed that it was.
The professor then picked up a box of pebbles and poured them into... 阅读全帖 |

我从来没有制作过jar文件，但用过很多别人做的，从来没问题。但是今天自己做了一
个，但是怎么也不行。具体是这样的。
1. 一个月前, 我写了一个程序A作计算。这个程序包括几个classes，都属于default的
package.
2. 这两天又写了一个程序B，也包括几个classes，都属于一个package叫做“
DataManagement”.
3. 今天想把程序A的功能包含在程序B中，于是就把A中的所有的classes放进一个jar文
件叫做“myjar.jar”。这个jar文件本身表面上看不出问题，能够解压。
4.在eclipse里通过"Add External Jars"把“myjar.jar”加入程序B的library里，这
样project的build path里就有了。我以前也是一直这样用别人的jar文件的，从来没有
问题。
5. 在程序B中准备引用“myjar.jar”中的classes，但是不成功，编译总是出错，就是
不能识别class。
6. 然后又又写个小程序C来测试。程序C中的classes都属于default的package。在程序

发帖数: 26 | 4 for example, the structure in the jar file is
edu.cc.ffm. The name of the jar file is bc.jar
suppose my java file is hell.java
at the beginning of hell.java, I add
package edu.cc.ffm;
then use javac -classpath bc.jar hell.java to get hell.class
next I extract bc.jar and move hell.class to edu\cc\ffm
finally use jar cf bc.jar *.* to create a new bc.jar
My question is, when I use import edu.cc.ffm.hell;
it generates error saying import arguments are not correct.

发帖数: 3845 | 6 say if my main class name is SendEmail.java, there are
also other small clases. This SendEmail.java imports
javax.mail which is a part of j2ee.
if I don't jar all the classes. I use
% java SendEmail
at the command line, everything works smoothly.
However, if I jar everything in one SendEmail.jar, when I use
% java -jar SendEmail.jar
or
% java -classpath (path of j2ee) -jar SendEmail.jar
it will report run-time error, such as javax.mail.Address not found. |

发帖数: 54598 | 7 在macosx下我现在的java版本只升级到5.0
就是死活不更新到6.0，我也没办法，控制不了
5.0下macosx如果光用缺省的环境，在ide中是找不到jnlp相关的jar包的
如果找不到相关的jar包，编译就无法通过
而事实上如果你去访问一些jnlp，也就是webstart发布的文件
你会发现，那些功能确实是可以用的
那说明有些包被隐藏了起来
经过不屑的搜索，终于发现了该死的javaws.jar包的所在
在
/System/Library/Java/Support/Deploy.bundle/Contents/Resources/Java/javaws.
jar
但是eclipse等编译器对于Deploy.bundle是默认无法打开的
所以需要做的就是手动打开Deploy.bundle，用右键点击选择show package content
然后把这个jar包给拷贝出来，放在某个地方
再在eclipse里面加入这个jar的支持，这样就可以编译通过了
nnd，搞得我半死 |

发帖数: 3845 | 9 I have put several java classes in a Jar file, one class
is the main entry, so I also put the main class information
in the manifest file.
However, when my class call j2ee classes (say java mail class),
"java -jar xyz.jar" always report can't file class error,
even i put -classpath c:\j2eeinstalpath\lib\j2ee.jar in the command.
There is no problem if i don't use jar file at all.
I wonder if this is the limitation of Jar? Thanks. |

发帖数: 16824 | 13 我用Eclipse写的一个jar, 调试的时候毫无问题，编译打包成jar以后独立运行就会出
一个bug。后来发现是跟JRE有关的，调试的时候用的是64位JRE, 独立运行的时候用的
是32位JRE。而且我没有办法在独立运行的时候调用64位JRE, 就算我直接用64位的java
.exe -jar启动这个jar, 从Task Manager里看调用的还是32位。有没有什么办法能让这
个jar独立运行的时候调用64位JRE啊？
我的环境是64位windows 7, 32位和64位JRE都装了，Eclipse是64位的。 |

发帖数: 140 | 18 我下载了一个.jar文件, 想在我的程序中用里面的class什么的.
请问在JBuilder 7中, 如何使用呢?
I see that the .jar file (actually a zip file, I know that), in the jar file,
there are folders and .class files. I think I can extract/unzip them
to the same folder as in my program, then import xx.xx.xx.class.*;
But I think there is a way to use the classes in the .jar file without
unzip the file.
How can I do it and use it from my java program? (in JBuilder).

发帖数: 764 | 21 1 - 我不知道理解你说的没有。在程序B中，在程序A中所有classes还用default
package的时候，没有import任何东西，在程序主体中也可以直接用jar文件中的
classes.但是程序A中所有classes改了package后就不可以了。程序C怎么也不行。
2 - Ctrl+shift+O没反应，但是Ctrl+shift+T能够找到在jar文件中所有的classes. 我
不知道这意味着什么。

You want to remove the jar from system lib and add it to your project. If
you need to build and ship your project, not run from within eclipse every
time, you want to do that any way.
If you really want the jar to be managed and shared, try popular solution
