Replace component class in wdk 6.5

Hello,

I need to ovveride a behavior class in docuemntum 6.5.

Coming for documentum 5.2.5 I used to extend all config files. In the documentation, it says to use replace path to override elements.

So I customized the menubar jsp and my new component xml file successfully loads my custom jsp.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<scope>

<start>/custom/menubar/menubar.jsp</start>

</replace></component>

</scope>

</config>

My question is:

If I want to ovverride the component class itself (the java file MenuBar.java) do I add another "replace path" with the path to my new java file in the same xml file? or do I have to create a new config file in addition to this one?

An example for replacing two elements (the jsp and the java file would be helpful.)

Thanks!

Do you really need to modify the component?

Can you simply extends it?

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<scope>

<pages>

<start>/custom/menubar/menubar.jsp</start>

</pages>

<class>your.custom.package.to.your.class.MenuBar</class>

</component>

</scope>

</config>

Thanks Marco,

That works perfectly after adding id="menubar" to the component tag.

When I tried to use modifies it was because in the wdk documentation it says:

In earlier versions of the Web Development Kit, you would extend and override the configuration

information files that come with the product as shipped. That approach still works. However, in

Version 6, you have the option of modifying the user interface by adding, removing, or replacing

individual configuration elements. The new approach makes it more likely that your customizations

will continue to work with future releases without having to make modifications.

So I assumed it was a better approach but using extend works!

"option" being a keyword here.... modifies is very good for small tweaks, e.g. set default document type to be created.

I use modifies if I can but extends is eaiser. Sometimes I use extends first and later convert to modifies if I have a chance. Added some example XML to this post where I use both

Biggest problem with extends was stupid people copying the entire component definition and then only changing 1 or 2 lines. That stupid stuff breaks upgrades.
