I've been able to do a rollback under most cases when the install fails. There are some caveats however.
I added custom code in the pre-install phase. The handler gets called in the pre-install and install phases but does not seem to get called during the post-install phase.
Code sample below. Not that the real work of the rollback handler is in the class YourRollbackHandler.
package com.install.installanywhere;
import com.zerog.ia.api.pub.CustomCodeAction;
import com.zerog.ia.api.pub.InstallException;
import com.zerog.ia.api.pub.InstallerProxy;
import com.zerog.ia.api.pub.RollbackRegister;
import com.zerog.ia.api.pub.UninstallerProxy;
public class CancelAction extends CustomCodeAction {
public void install(InstallerProxy proxy) throws InstallException {
RollbackRegister register = (RollbackRegister) proxy
.getService(RollbackRegister.class);
register.addHandler(new YourRollbackHandler());
}
@Override
public String getInstallStatusMessage() {
return null;
}
@Override
public String getUninstallStatusMessage() {
}
@Override
public void uninstall(UninstallerProxy proxy) throws InstallException {
}
}

when does the code go to roll back handler?
Is it when pressing cancel? I want to rollback if the any failure occurs during my install/postinstall actions..how do i handle that.?
