This entry is part of the Maximo Java Development series. To query a Maximo table using Java you need to perform the following steps: Get a reference to the MboSet. Specify a where clause. Loop through the MboSet and fetch Mbos. The following example shows how to retrieve all the assets located in BEDFORD site. […]
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 […]
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 […]
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 […]
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 […]
This entry is part of the Maximo Java Development series. When you are in an Mbo class or you already have a reference to an Mbo object is it possible to retrieve the related records using Maximo object relationships as defined in the Database Configuration application.For example the ASSET object has a relationship called ACTIVEASSETMETER to the […]
This entry is part of the Maximo Java Development series. One of the biggest issues when implementing Java customizations in the Maximo Business Objects layer is to know what is the best method to override to achieve a specific goal.Here I have listed the most common usages of the the main methods in Mbo, MboSet and […]
This entry is part of the Maximo Java Development series. Debugging is a great aid in developing Maximo/TPAE customizations in Java. This powerful technique, albeit simple, is too often ignored or neglected by less experienced developers. In this tutorial I will show how to connect Eclipse to a remote Maximo server in debug mode.Here we go. Enable debug […]
This entry is part of the Java MBO performance optimization golden rules series. Sometimes you have to perform some complex logic or you have to join several tables to retrieve a piece of data. In other cases there is a piece of code where performance is critical. In such cases it may be hard to […]
This entry is part of the Java MBO performance optimization golden rules series. A not well tuned SQL query is often the biggest contributor to elapsed time taken by Maximo Business Objects (MBO) logic. A general example of this is the use of IN or NOT IN in SQL where clauses. Avoid IN or NOT IN […]
