Hi Jacobo,
normaly it compiles without this error.
Look into findIzPackResource.this method searches in your compiler jar file for the
needed resources.
Please look into standalone-compiler.jar; there should be stored uninstaller.jar in path lib\.
If not, it is missing at generating standalone-compiler.jar. Build stanalone-compiler.jar only
in a full IzPack project with installed sources.
I do not work with the standalone-compiler.jar. May be you have to set izpackdir also you should
not need it.
Cheers
Klaus

Subject: [izpack-users] Exception when adding an Uninstaller (was) Re: Re:Integrating Izpack with eclipse
Thanks for your help Klaus, I've managed to run the compiler now. I'm using the standalone compiler at this moment, and it looks that my plugin works well with it.
By the way I'm Having another problem at this moment.
This is a typical izpack xml file that my plugin generates:
<?xml version="1.0" encoding="UTF-8"?>
<installation version="1.0">
<info>
<appname>jaco</appname>
<appversion>dsfa</appversion>
<authors>
<author email="fdasadsf" name="asdfads"/>
</authors>
<url> http://www.com.com</url>
<javaversion>1.5</javaversion>
</info>
<guiprefs height="600" resizable="no" width="800"/>
<resources>
<res id="InfoPanel.info" src="/Users/jacobo/Desktop/export/tmp/readme.txt"/>
</resources>
<panels>
<panel classname="HelloPanel"/>
<panel classname="InfoPanel"/>
<panel classname="InstallPanel"/>
</panels>
<packs>
<pack name="Main" required="yes">
<description>Main Pack that does all the installation</description>
<file dir="/Users/jacobo/Desktop/export/linux.gtk.x86" os="unix" override="true" targetdir="/opt/jaco"/>
<file dir="/Users/jacobo/Desktop/export/win32.win32.x86" os="windows" override="true" targetdir="c:\Program Files\jaco"/>
<file dir="/Users/jacobo/Desktop/export/macosx.carbon.x86" os="mac" override="true" targetdir="/Applications/jaco"/>
</pack>
</packs>
</installation>
When running this file, I get a null pointer exception, this is the code:
Caused by: java.lang.NullPointerException
at org.apache.tools.ant.Task.log(Task.java:346)
at com.izforge.izpack.ant.IzPackTask.packagerMsg(IzPackTask.java:142)

at com.izforge.izpack.ant.IzPackTask.execute(IzPackTask.java:234)
... 67 more
--- Nested Exception ---
Looking at izpack source code, the exception comes in CompilerConfig.java, in this portion of code:
XMLElement uninstallInfo = root.getFirstChildNamed("uninstaller");
if (validateYesNoAttribute(uninstallInfo, "write", YES))
{
/* thisline gives the error*/ URL url = findIzPackResource("lib/uninstaller.jar", "Uninstaller", root);
compiler.addResource("IzPack.uninstaller", url);
if (uninstallInfo != null)
{
String uninstallerName = uninstallInfo.getAttribute("name");
if (uninstallerName != null && uninstallerName.endsWith(".jar")
&& uninstallerName.length() > ".jar".length())
info.setUninstallerName (uninstallerName);
}
}
This happens if I include uninstall element on the xml or not. It looks like it does not find uninstaller.jar, So I tried to add it to the same folder where standalone-compiler.jar is. But did not worked.
¿Is this a Bug?
