Java install and run a programm

New page

How-To install java on the target and run a java program.

==Install java packages GNU Classpath and JamVM==

Add the GNU Classpath and JamVM to your target:

<pre class="host">
$ make menuconfig
</pre>

Goto the buildroot packages and enable the Java package and from the java sub menu select both GNU classpath and JamVM packages.
You have to rebuild a new rootfs et update your target

{{Warning| If your java sub menu is empty then you have to select it first from the upper menu.}}

==Run a java programm==

You can run your java program compiled for your host.
Upload your jar, zip or class files to the target then use the jamvm command to run your program.

<pre class="apf">
jamvm -jar myprog.jar
</pre>

If your program requires some other libraries, you will have to install these on the target first or build your program to provide your code and these libraries.

 ==Java programs and native libraries==
-The use of native libraries can be required when plateform-specific features are needed. In such a context, Java Native Interface (JNI) is helpful. It is included in the jamvm package but another tool called SWIG (Simplified Wrapper and Interface Generator) facilitates the design of this interface.
