[izpack-user] problem with <executable>

[Chad Berkley]

Hello,

I'm trying to get a small shell script to execute using the <executable>
tag. It seems to work fine on one computer, but not on others and I'm
baffled as to why it won't run. I can't seem to get any error stream
from the computers where it does not work, though I know an error is
occurring because a small dialog that says "continue?" yes/no pops up at
the end of the installation (when the script is supposed to execute).
I think for some reason, the error message is not being generated or
not being included into the dialog.

So my question is, is there a way to get at the error stream during an
izpack installation? I'd like to see why the script is not executing on
some of my test machines.

Here's the executable statements that I'm using and the script that it's
executing:

<pack name="R (2.6.2) osx" required="no" os="mac" id="r-2.6.2-mac">
<description>R (2.6.2) for Mac OSX - If you choose to install
this option, the R installer will be launched at the completion of
the Kepler installation.
</description>
<file targetdir="$INSTALL_PATH/" src="R-2.6.2-osx.dmg" os="mac"
unpack="false"/>
<executable type="bin" stage="never"
targetfile="$INSTALL_PATH/loaddmg.sh" os="mac" />
<executable type="bin" stage="postinstall"
targetfile="$INSTALL_PATH/loaddmg.sh" os="mac" />
</pack>

loaddmg.sh:
#!/bin/sh
hdiutil mount R-2.6.2-osx.dmg
open /Volumes/R-2.6.2/R.mpkg/

Once the installer finishes, I can execute the script from the command
line normally so I know it's not a permission or path issue (within the
script).

Thanks for any help.

Try out starting the installer from a console window / the command line
as follows:

java -DTRACE=TRUE -jar yourInstaller.jar

This gives you lots of information, all printed to console.

Thanks, that's exactly what I was looking for.

Hi List!

At uninstall, I want to run a script which removes a service under windows. I include the following in my install.xml:
<executable targetfile="cmd /c start $INSTALL_PATH/bin/scriptname.cmd" stage="uninstall" failure="warn" os="windows" keep="true"/>

The "cmd /c start" is there to open a new console window. But this doesn't work. If I use

<executable targetfile="$INSTALL_PATH/bin/scriptname.cmd" stage="uninstall" failure="warn" os="windows" keep="true"/>

directly, then the uninstaller hangs in case the script waits for a keystroke. To avoid this, I tried to put in the "cmd /c start" to run the script in a console window, which can be closed by the user.

Unfortunately, this technique doesn't work. The uninstaller gives a warning that the program cannot be found.

If I put the line
<executable targetfile="notepad.exe" stage="uninstall" failure="warn" os="windows" keep="true"/>
Next to the other executable-line, notepad is executed as you would expect it.

I cannot adjust the script, because I get it from another group and it might be modified later.

Best Regards,
Daniel Strecker

Hi Daniel,

Unfortunately, start is a shell command, so in fact there is not a "start.exe" anywhere that executes when you type this command in. That's why Java can not find it and you get the warning.
My approach is to use Windows Scripting Host like this:

<executable targetfile="${ENV[windir]}\System32\CScript.exe" keep="true" stage="uninstall" failure="warn" os="windows">
    <args>
        <arg value="$INSTALL_PATH\myscript.vbs"/>
    </args>
</executable>

Then, write a myscript.vbs like this:
CreateObject("Wscript.Shell").Run "cmd /C ""$INSTALL_PATH\therealscript.bat""",0,false

I must confess this is not an elegant solution, but works.

Maybe we could add a new parameter to the <executable> tag as a feature request in order to allow some program to run without waiting for it to end.

Best regards,

We have a similar requirement, and we have wrapped our scripts into a batch file and following works for us.

<executable targetfile="$INSTALL_PATH/pathToBatchFile/bin/install.bat" stage="postinstall" keep="true">

</executable>

This doesn't seem to be working on izpack 5.0.0-rc1-SNAPSHOT

    <packs>

        <pack name="Core" required="yes">

            <description>The core files</description>

            <executable stage="postinstall" targetfile="notepad.exe" keep="true"/>

            <executable stage="uninstall" targetfile="$INSTALL_PATH/bin/myapp.bat" keep="true">

            <args><arg value="remove"/></args>

            </executable>

        </pack>

    </packs>

Sorry, that is working for me now
