I am trying to solve this issue: PWC6345: There is an error in invoking javac. A full JDK (not just JRE) is required

We have a third-party Java app that uses a Jetty server but looks like either the JDK is missing or not reachable where it is located?

In /usr/bin I see:

java
javaws
jexec

No javac so probably no JDK installed.

The box is Debian "Squeeze" with the following:

java -version
java version "1.6.0_18" OpenJDK Runtime Environment (IcedTea6 1.8.13) (6b18-1.8.13-0+squeeze2) OpenJDK Client VM (build 14.0-b16, mixed mode, sharing)

What is this the right Squeeze package?
apt-cache search javac
default-jdk - Standard Java or Java compatible Development Kit
openjdk-6-jdk - OpenJDK Development Kit (JDK)
Something else? Thanks!

Actually, depending on the web application you want to run in Jetty, it might be better to install the Sun JDK ( sun-java6-jdk , which would automatically divert all java/javac/... symbolic link to the Sun JDK ), because it often provides a much better compatibility with some applications.

The default-jdk should at least provide javac, so the error might indicate that you have a compatibility issue (It does NOT say that javac could not be found, but that javac failed to execute correctly).

The error log already shows the problem: A full JDK (not just JRE) is required

I'd recommend to select default-jdk

I also found: sun-java6-jdk - Sun Java(TM) Development Kit (JDK) 6. Would you still recommend default-jdk? –  Slinky Jan 3 '13 at 14:07
    
As this one is the "most original" JDK I then would recommend you to use this one but I assume that default-jdk is equally. –  Simon Strasser Jan 3 '13 at 14:18
    
OK. Will try that and report back –  Slinky Jan 3 '13 at 14:24
