I get all rows in displaytag table same values i.e. It displays same values for all rows (i.e. last row values)
Below is the Action class snippet where I set the values in formbean
public class FormIdSearch extends Action {
ResourceBundle rsBundle = ResourceBundle.getBundle("com.mindcraft.resources.ApplicationResource");

The issue is that you are using the single instance of FormBean (the one that’s passed into the Action by Struts) in getDocumentMetaData. So your collection (formbeanCol) ends up with each entry pointing to the same FormBean instance. So in your last iteration you will be setting the values for this FormBean to the last data row, and all entries point to this.
I would advise not using FormBean for this (use a simple bean instead), and create a new instance each time in getDocumentMetaData. If you do want to continue to use FormBean then a simple fix is to change getDocumentMetaData as follows:
This issue does highlight the dangers of using ‘global’ variables (in this case formbean and formbeanCol).
FYI, you should avoid instance variables in Actions as Actions in Struts 1.x are globally scoped, i.e. one instance will be shared between different requests. Your formbeanCol will probably get increasingly large and you may get concurrency issues. Just declare formbeanCol as a local variable in the execute method.
