How to turn an identifier ie wt.epm.EPMDocument:42864420 into an EPMDocument object?

[RandyJones]

I am working on a jsp page that asks the user to select some specific EPMDocument
versions in a form. When submitted the form is returning the identifiers of the
object(s) selected. The identifiers are what you get from:
PersistenceHelper.getObjectIdentifier(epmDoc)

The jsp page is outputting the form checkbox as follows:
out.println("\t\t<td><input type="checkbox" name="checkbox" value="\"" +=" persistencehelper.getobjectidentifier(epmdoc)=" +=" &quot;\&quot;="></input></td>");

So upon submission I have an array of string values like this:
"wt.epm.EPMDocument:42864420", "wt.epm.EPMDocument:43075131", etc

So how do I turn take this string value and turn it into an EPMDocument object?

String epmID = "wt.epm.EPMDocument:42864420";

EPMDocument epmDoc = ?????(epmID);


Thanks

Hi Randy,
Try the following code and see if it works.

import wt.fc.*;
import wt.epm.*;

reference="OR:wt.epm.EPMDocument:42864420";
ReferenceFactory factory = new ReferenceFactory();
Persistable persistable = factory.getReference(reference).getObject();
if(persistable!=null && persistable instanceof EPMDocument) {
EPMDocument doc = (EPMDocument)persistable;
System.out.println("EPMDocument Name :"+doc.getName());
}

Really all you need to do is

ReferenceFactory ref = new ReferenceFactory();

EPMDocument epdmDoc = ( EPMDocument )ref.getReference( epmID ).getObject;

This also works:

Persistable obj = BasicWebjectDelegate.getObjectByUfid(obid);

Then the persistable obj can be cast to its corresponding windchill object type:

EPMDocument epm = null;
If(obj instanceof EPMDocument) {
epm = (EPMDocument) obj;
}

This is a summary of the responses to my question. Some of these were sent to the list and some were sent only to me.

String epmID = "wt.epm.EPMDocument:42864420";

EPMDocument epmDoc = ?????(epmID);

Basically there were 3 approaches given to turn the string identifier back into an EPMDocument.

Given we have this:

String epmID = "wt.epm.EPMDocument:42864420";

===================================================================

1st approach is using the ReferenceFactory like this:

ReferenceFactory rf = new ReferenceFactory();

EPMDocument epmDoc = (EPMDocument)rf.getReference(epmID).getObject();

===================================================================

2nd approach is ObjectIdentifer and ObjectReference like this:

ObjectIdentifier oid = ObjectIdentifier.newObjectIdentifier(epmID);

EPMDocument epmDoc = (EPMDocument) wt.fc.ObjectReference.newObjectReference(oid).getObject();

===================================================================

3rd approach is to use BasicWebjectDelegate:

EPMDocument epmDoc = (EPMDocument) wt.adapter.BasicWebjectDelegate.getObjectByUfid(epmID);

===================================================================

I haven't yet decided which approach to use yet. I have tried all 3 and they work.

I want to thank all of you that responded. Per usual the users on this list are a fantastic resource.
