[izpack-user] IzPack 4.2.1 installation problem

[Naureen Akhoond]

Hello,

I am trying to install IzPack 4.2.1 through the IzPack-install-4.2.1.jar which I downloaded from http://izpack.org/downloads/

I have j2sdk_1.4.0_1 installed on my system having window xp. When I run the command:

java -jar d:\softwares\IzPack-install-4.2.1.jar

I get the following exception,

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/izforge/izpack/installer/Installer (Unsupported major.minor version 49.0)
at java.lang.ClassLoader.defineClass0(Native Method)

at java.lang.ClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClassInternal(Unknown Source)

Kindly guide me how do I install it. Is there any .exe file for the installation of the IzPack.

Thankyou

Hi,

You need Java5+.

Cheers

Hello,

Thankyou for your quick response.

IzPack has been installed successfully after installing the java5, but the confusion is that why it did not prompted me for the java5 or installed it automatically. Probably because it is not in the SFX format (Please correct me if I am wrong...)

I have made the sample installer successfully :)

Now I want to know about getting started with the Glass Fish. What is the difference between GlassFish v2.1 b60e and GlassFish V3 Prelude.

The reason of using Glass Fish is that I want to make some user input panels (Probably this is what it serves for ... right?)

Thankyou

Code compiled for Java 5 won't run under Java < 5, the JVM simply
throws an error.

You will have to look at the GlassFish project then: http://glassfish.org/
