Creating a New Mbo Class

Hello;

One of the basic java functionality is to create new mbo’s and changing its default behaviour. For example we can create a new mbo as the child of Workorder. And assume there is a relationship between workorder and newMbo as wonum=:wonum. When we add a new record from the user interface, new record’s wonum is not populated automatically. So we have to extend psdi.mbo.Mbo to automate this. Here is how it is done….

    public newMbo(MboSet ms) throws MXException, RemoteException {
        super(ms);
    }
 
    public void add() throws MXException, RemoteException {
        super.add();        
        MboRemote mboremote = getOwner();
        setValue("WONUM", mboremote.getString("WONUM"), 2L);
 
 
    }
 
}

Then you have to compile and rmic these files. Then Go to the database configuration find your object. Enter ‘custom.newMbo.newMboSet’ to the class…

Configure DB
Build Maximo.ear
Deploy Maximo.ear

Tip: It is better to make Wonum field readonly on user interface. Users must not change the field from the user interface

Then you’re good to go….

Have a good day…

    Hi,

    I’m very new to maximo and trying to get familiar with Maximo 6.2.2 development environment. May i know what is the procedure to add a new application into maximo and make it function with my own class? This is because i had create my mbo (using Databse Configuration) and interface (using Application Designer). I also compiled a folder called myapp (consists of the basic classes) and deployed it (also assigned it to my mbo). But it didn’t function as I expected. One thing i noticed is the service of my mbo still remain as ‘CUSTAPP’.

    PS: what do u mean by ‘rmic’ the file?

    Have a nice day…

    Hello;

    It is actually easy and enjoyable to develop new applications and make them use your own classes. You can do it via application designer and database configuration..(Write your classname to the classname field of your object in database configuration).. I suggest you to use Maximodeveloper addon for eclipse.. It really makes your job easy.. It directly creates classes and rmic them…

    You can have that addon: http://maximodeveloper.sourceforge.net/

    Have a good day…

    Hi,

    Do I need to install Maximo 6 on my PC in order to use the maximodeveloper plugin? Or just the Maximo folder will do?

    solve error “Connection to database not present, could not initialize Maximo developer.”
    this because password of database is encrypted in maximo.properties
    so use maximo.properties-oirg
