You can include your jar files in the "javac" command using the "-cp" option.

<pre><code>javac -cp ".:/home/path/mail.jar:/home/path/servlet.jar;" MyJavaFile.java
</code></pre>

Instead of "-cp" you could also use "-classpath"

<pre><code>javac -classpath ".:/home/path/mail.jar:/home/path/servlet.jar:" MyJavaFile.java
</code></pre>

You could including the jars every time you compile by setting the environment variable "CLASSPATH" correctly. The environment variable will store the path where the jars and classes that needs to be used for compiling/executing any java file. You will not have to include the jars individually every time you compile you file.

Different machines have different methods to set the classpath as an environment variable.
The commands for Windows, Linux, etc are different.

<pre><code>javac -cp ".;first.jar;second.jar;third.jar" MyJavaFile.java

blocks|key|643554|text|这将创建.class文件：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|643555|javac+-classpath+"[jarname+with+specified+path]"+[java+filename]|code-block|syntax|javascript|643556|这将执行class+file：|643557|java+-cp+[jarname+with+specified+path]:+[java+filename]|643558|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

You need to specify the dependencies in compile time as well as runtime

To compile use this format

<pre><code>javac -cp "*.jar;classfile_path" filename.java
</code></pre>

Example:

<pre><code>javac -cp "ojdbc6.jar;c:\programs" Main.java
</code></pre>

blocks|key|429137|text|有时，进行以下更改会起作用：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|429138|java+-cp+".;%25CLASSPATH%25"+classfilename+|code-block|syntax|javascript|429139|注:在Windows上。对于linux，请改用$CLASSPATH。|offset|length|style|CODE|429140|entityMap^0|0|0|N|A|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

some times making following change works: 

<pre><code>java -cp ".;%CLASSPATH%" classfilename

Note: ON Windows. For linux use <code>$CLASSPATH</code> instead.
