[izpack-user] Missing Panel in Linux Console mode

[Andy Bowes]

Hi

 

We have created an installer using IZPack and it works fine on Windows & Linux using the GUI but we hit a problem when it is executed on the Linux command line with the ‘–console’ option.

 

One of the steps (which allows the user to specify a data directory) seems to be skipped during the installation process and this causes the following stack trace to be produced at the end of the installer:

 

[ ERROR: Internal error occured : java.lang.NullPointerException ]
java.lang.NullPointerException
at java.util.Hashtable.put(Hashtable.java:514)
at java.util.Properties.setProperty(Properties.java:161)
at com.izforge.izpack.installer.AutomatedInstallData.setVariable(Unknown Source)
at uk.gov.nhs.spine.dbs.installer.EscapePaths.escapePathAndStore(EscapePaths.java:35)

at com.izforge.izpack.installer.UnpackerBase.informListeners(Unknown Source)
at com.izforge.izpack.installer.Unpacker.run(Unknown Source)
at java.lang.Thread.run(Thread.java:744)

 

Our list of Panels is quite small and it is the UserPathPanel which is skipped:

    <panels>

        <panel classname="HelloPanel" />

        <panel classname="TargetPanel" />

        <panel classname="UserPathPanel" />

        <panel classname="UserInputPanel" id="UserInputPanel.ServerDetails" />

        <panel classname="UserInputPanel" id="UserInputPanel.OrganisationDetails" />

        <panel classname="PacksPanel" />

        <panel classname="SummaryPanel" />

        <panel classname="InstallPanel" />

        <panel classname="SimpleFinishPanel" />

    </panels>

 

I can’t see anything obvious that would cause this behaviour, has anyone seen it before?

 

Thanks

Andy

Which version of IzPack do you use?

The latest versions 5.0.0-rc1 (release candidate), 5.0.0-rc2-SNAPSHOT added several more panel implementations and skip unimplemented panels instead of throwing ugly exceptions.

Hi Andy,

Which version of IzPack do you use ?

I you use a 5.0.0-betaXX or the 5.0.0-rc1, UserPathPanel has no console
implementation for now. See these issues on Jira:

Console installation support for all built-in panels
(http://jira.codehaus.org/browse/IZPACK-871)

Create console implementation of the UserPathPanel
(http://jira.codehaus.org/browse/IZPACK-934)

Hi

We are using 4.3.5, haven't upgraded to the RC.

Is there an alternative approach that can supply the same functionality as the UserPathPanel panel if this is not supported in console mode? Ideally we would need to perform the same sort of path validation & existence checking that is supplied by the UserPathPanel.

Thanks
Andy

I know that this is denoted at a low priority but is there an expected resolution date for the JIRA : http://jira.codehaus.org/browse/IZPACK-934 ?

We are looking to live with our application in June and so either need this issue resolved or an alternative for the implementation of the UserPathPanel in console mode.

[Andy Bowes]

What is the best way to show/hide panels if the installer is being run in 'console' mode so that I can display an alternative panel to the GUI representation?

I can see the 'os' setting that allows the switch based on operating system but I cannot see a similar option that acts as a conditional based on gui/console mode.

[René Krell]

Did you try binding a condition on the <panel> definition? See http://docs.codehaus.org/display/IZPACK/Panels

[Andy Bowes]

I can see pre-defined conditions based on the OS of the install but I cannot see how to use a condition to detect if the installer is being run in console mode.  Is there a pre-defined condition or a simple way to detect if the installer is being run in GUI or console mode?

 

Sorry for the newbie questions but it’s the first time that I’ve used izpack.
