Reset the value of a field when another field is modified
This entry is part of the Maximo Java Development series. Today I want to share with you some Java sample code to reset the value of a field when another field is modified. In the example below I have implemented a little piece of logic to reset the WORKORDER.SUPEVISOR field when the WORKORDER.OWNERGROUP is modified. Here is the Java code. package cust.psdi.app.workorder;import psdi.mbo.*;import psdi.util.*;import java.rmi.*;/** * Custom field class to reset the supervisor when the Owner Group is changed */public class FldWOOwnerGroup extends psdi.app.workorder.FldWOOwnerGroup{ public FldWOOwnerGroup(MboValue mbv) throws MXException { super(mbv); } public void action() throws MXException, RemoteException { if (!getMboValue().isNull() && !getMboValue().equals(getMboValue().getPreviousValue())) { getMboValue("SUPERVISOR").setValueNull(NOACCESSCHECK|NOVALIDATION_AND_NOACTION); } super.action(); }} Deploy the FldWOOwnerGroup.class file in your Maximo source tree and attach it on WORKORDER.OWNERGROUP field using the Database Configuration application.

How to create Maximo demo database (MAXDEMO)
The Maximo contains an extremely useful command to create a demo database filled with a sample data. This can be really helpful when learning haw Maximo works. Tho create the demo database perform these steps. Stop the application server (MXServer) Open a command prompt Move to:[SMP_DIR]\maximo\tools\maximo Issue the following command: maxinst -s[INDEXTABLESPACE] -t[DATATABLESPACE] By default both tablespaces are equals to MAXDATA so the following command should work. maxinst -sMAXDATA -tMAXDATA To create an empty databasse add the -imaximo parameter.

IBM's mobile solutions for Maximo
This article is outdated! IBM Anywhere is now available. In several forums and groups I have recently seen, there is some confusion around the current IBM’s mobile solutions for Maximo so I will try to give my personal view on this hot topic. Before going on keep in mind that this analysis is updated to the current situation as of October 2012 and may become outdated in few months. Overview

Custom condition Java class
Sometimes standard Conditional Expressions are not enough. Sometimes the logic to implement is too complex to be implemented using an SQL expression. In such cases Maximo allows to implement the condition logic in a custom condition class using Java. To implement a condition class you must extend psdi.common.condition.CustomCondition and override evaluateCondition and toWhereClause methods. Here is a sample class. public class IsIssueProblem implements CustomCondition{ public boolean evaluateCondition(MboRemote mbo, Object obj) throws MXException, RemoteException { if (mbo.getString("ISSUETYPE").equalsIgnoreCase("PROBLEM")) { return false; } else { return false; } } public String toWhereClause(Object obj, MboSetRemote mbs) throws MXException, RemoteException { // ensure this method is not called by throwing an Exception throw new MXApplicationException("", ""); }} The provided snippet works for all Conditional Expression usages except for QUALIFIED security restrictions. In this cases you have to implement the toWhereClause method to return a valid SQL clause.

How to display a YES/NO dialog and get user input
This entry is part of the Maximo Java Development series. In this little article I’m going to show how to display a dialog box with Yes/No or OK/Cancel buttons and how to capture the user’s input to execute some custom logic. For example, you have a Java method attached to a button on the toolbar or to an action menu entry as described in this article and you want to display a warning message asking for confirmation before executing some processing.

How to check for null values
This entry is part of the Maximo Java Development series. A very common doubt when extending MBOs is what value returns the Mbo.getString() method when the target field has a null value. The answer is: It returns an empty string “”. Thus to check if the DESCRIPTION of an Mbo is empty or null you can use two basic approaches. getString("DESCRIPTION").equals("") or
