It's in the bin folder of your java JDK install (Java SE). If you only have the JRE installed you probably don't have it.

For posterity's sake, if you are trying to actually use jarsigner to sign a jar file (such as that of an applet) with a keystore, you'll need to reference jarsigner while running the command from the folder that your keystore is in: 

<pre><code>cd "C:\Program Files\Java\jre(version#)\bin"
</code></pre>

then

<pre><code>"C:\Program Files\Java\jdk(version#)\bin\jarsigner.exe" -keystore mykeystore (PATH TO YOUR .JAR)\MyJarFile.jar alias
</code></pre>

The above might be obvious, but it took me a few tries because I was trying to call jarsigner while inside the JDK folder, which had no knowledge of where my keystore was (in the jre directory!), so I hope this will help those who would like to see a usable syntax for that situation.

blocks|key|274752|text|当您在JAVA_HOME变量中只安装了JRE而没有安装JDK时，就会出现这个错误。不幸的是，您不能将这两个变量都安装在同一个变量中，因此您只需要用新的JDK安装路径覆盖该变量。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|274753|该过程应与安装JRE的方式相同|274754|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

This error comes when you only have JRE installed instead of JDK in your JAVA_HOME variable. Unfortunately, you cannot have both of them installed in the same variable so you just need to overwrite the variable with new JDK installation path.

The process should be the same as the way you had JRE installed

blocks|key|274790|text|对我来说，解决方案是将全局变量path设置为JDK。查看此处：https://appopus.wordpress.com/2012/07/11/how-to-install-jdk-java-development-kit-and-jarsigner-on-windows/|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|274791|entityMap|0|LINK|mutability|MUTABLE|url|https://appopus.wordpress.com/2012/07/11/how-to-install-jdk-java-development-kit-and-jarsigner-on-windows/^0|V|2Y|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

For me the solution was in setting the global variable path to the JDK. See here:

I have the Android SDK installed on both a Linux machine using open SuSE 12.1. I've used both machines to successfully build Android apps many times and sign them both with a debug key for testing and a release key from my own keystore, so it should be somewhere on each machine.

Using the command

<pre><code>jarsigner
</code></pre>

Returns a command not found error on both machines, however. I've looked in the Android SDK folder, JDK folder on Windows, and /usr/lib64/jvm/ but it's not anywhere I've looked.

I assume it must be under a different name. I've also run:

<pre><code> find -name jarsigner
</code></pre>

over the whole system on the Linux box with no success.

Where is jarsigner?

Android

Windows

Linux

Java

我使用open SuSE 12.1在两台Linux机器上都安装了Android SDK。我已经多次使用这两台机器成功地构建了Android应用程序，并使用用于测试的调试密钥和来自我自己的密钥库的发布密钥对它们进行签名，所以它应该在每台机器上的某个地方。使用命令jarsigner但是，返回在两台计算机上都找不到命令的错误。我已经在Android SDK文件夹、Windows上的JDK文件夹和/usr
