The import “javax.jnlp” cannot be resolved

Question

I am learning Java and trying to run some examples using Java web start.

However, I cannot seem to find that package javax.jnlp.

This same error

Answer 1

Can be found in jre/lib/javaws.jar in 1.7 and 1.8, as per: https://stackoverflow.com/a/13555413/829305

The jre/ directory can be found inside the jdk/ directory if you've only got the JDK installed.

Answer 2

You should add the path to javaws.jar file in your classpath. For example: "javac -classpath .:/path/to/javaws.jar webstart/*.java"

Answer 3

From the Oracle page:

The jardiff tool, jnlp-servlet.jar file, and jnlp.jar file can be found in the samples directory of the JDK.

On my comp it is in:

... /jdk1.6.0_23/sample/jnlp/servlet/jnlp.jar

---

For Java 7 you have to download Demos and Samples separately:

Windows x86 (32-bit) 15.62 MB jdk-7u4-windows-i586-demos.zip

Windows x64 (64-bit) 15.69 MB jdk-7u4-windows-x64-demos.zip

You will find jnlp.jar inside: jdk1.7.0_04\sample\jnlp\servlet\jnlp.jar
