Add some operations before or after the commitment of Create


I have two collections (just say coll_A and coll_B) in a Tamino database. And I used the X-Application to generate the JSP pages for coll_A.

Now, I want to add some operations before or after the commitment of Create / Delete through the JSP pages generated.

The possible operations being added are, for example:
1) after creating a record in coll_A, I want to add a record into coll_B which has some information relating to the record in coll_A.
2) after deleteing a record in coll_A, I want to delete the correspongding record in coll_B.

I need to make sure that “transaction” is being used. That means, just say, if the record in coll_B could not be deleted due to some unexpected reasons, the “delete” operation for the record in coll_A should be rolled back.

How can I add the Java coding before or after the commitment of the Create / Delete actions in the JSP pages? Do I need to modify the tag library? Any other simpler methods?

Can anyone help me? Thanks a lot!

a possible solution could be a plugin on document level. Assume your document of doctype ?docA? has to be committed. Then, the following action could be pluged in:

<xapp:action type=?commitA? ...>...</xapp:action>
</pre><BR><BR>The definition of this action must be added to your xapplication.xml file.<BR><BR><pre class="ip-ubbcode-code-pre">
   <document name=?DocA?>
    <action name=?commitA?
</pre><BR><BR>Here the name of the action is assigned to the method commitDocumentA that implements the functionality of the action, e.g.<BR><BR><pre class="ip-ubbcode-code-pre">
package myPackage.mySubPackage;

public class MyClass {
    public static void commitDocumentA(BusinessDocument doc, BusinessDocumentWorkspace ws) {
        Store s = ws.getStore();
        BusinessDocument docB =;
        if (...) {
           List docs = new ArrayList();

The class implementing the functionality must be compiled into the directory WEB-INF/classes of your application.

Using a plugin, it is not necessary to add a new tag. However, before starting with this task have a look into the documentation of X-Application 3.1.3. It contains a chapter about plugins.

The example I have written may contain errors and typos because I wrote it directly into the editor without trying out the code. If you have questions or problems with this example, send me a new post.
