[appengine-java] having trouble implementing gwt in existing gae app
I'm using Eclipse 3.4.1, GAE 1.3.1 and trying to use GWT 2.0.3. I've been working on my GAE app some time and that's working well - just want to spice up the front-end a little.

I followed the instructions presented by Google on the contains filter (:p.contains(lastName) but couldn't get it to work.

[appengine-java] Using UserService credentials with a SpreadsheetService
In my GAE/J web application, users authenticate via their google
account. I check to see they've signed into google via this code in
my jsp:
UserService userService = UserServiceFactory.getUserService();
User user = userService.getCurrentUser();
if (user == null)
response.sendRedirect("/index.jsp");
Is there anyway to use the user object above to query for that user's
spreadsheets? I'm thinking that it would involve using
user.getAuthDomain() but not sure if I'm right here. For instance,
would this work?... service.setAuthSubToken(user.getAuthDomain());

[appengine-java] Re: google docs error when trying to retrieve docs in GAE/J
I've tried looping through the document list as you suggested in
number 2 by running the below code:
for (int x = 0; x < 10; x ++) {
try {
DocumentListFeed feed = service.getFeed(documentListFeedUrl,
DocumentListFeed.class);
for (DocumentListEntry entry : feed.getEntries()) {
System.out.println(entry.getTitle().getPlainText());
}
}
catch (Exception ex) {
System.out.println("Document List error " + x + ": " +
ex.toString());
}
}
Still unfortunately getting the
"com.google.gdata.util.ResourceNotFoundException: Not Found" error -
I'm using Eclipse for my IDE - I have has imported libraries the
following:
import java.net.URL;
import com.google.gdata.client.docs.DocsService;
import com.google.gdata.data.docs.DocumentListEntry;
import com.google.gdata.data.docs.DocumentListFeed;
Shouldn't need anything else, right? Also, I don't have a "bin"
folder - I have a "lib" folder though...
Thanks.

post and found it should be
"http://docs.google.com/feeds/default/private/full"; - Just a little
different but that did the trick...

[appengine-java] Re: javax.jdo.JDOObjectNotFoundException: Could not retrieve entity of kind Transactions with key Transactions(Transactions(67))
Finally found a way in case anybody was curious... Unfortunately, I
have to loop through all of my pertinent records until I have a match
on the keys. If anyone can suggest a different way (that works)
that's more efficient than below, do tell...
Query query = pm.newQuery(Categories.class, "userName == '" +
user.getNickname() + "'");
List results = (List) query.execute();
for (Categories cat : results) {
if (cat.getKey().toString().equals(reqParm)) {
pm.deletePersistent(cat);
}
}
query.closeAll();
I appreciate the input of datanucleus though he/she wasn't able to
ultimately lead me to the solution.

This is strange - when I retrieve the object after persisting via "JDOHelper.getObjectId(obj)", I get an object back no problem. Then, before trying to delete the object, I do "pm.newObjectIdInstance (Categories.class, key)" and I get a NullPointerException. I know in this post I've put in "Categories", but I'm doing the same thing using the Categories class as I am the Transactions class - the Categories class is just easier to work with.

[appengine-java] Re: javax.jdo.JDOObjectNotFoundException: Could not retrieve entity of kind Transactions with key Transactions(Transactions(67))
Let me be more specific about what's happening...
1. In my jsp, I loop through a list of Transactions and display them
in a table. At the right-most column, there's a delete button.
2. When that delete button is pushed, an indicator ("delete") plus
Transaction.getKey() are stored as a request parameter. Also, a
servlet is called to handle the delete button click.
3. Inside the servlet, this is the code that's used to process any
request parm that has delete in it...
for (Enumeration e = req.getParameterNames(); e.hasMoreElements
();) {
parms = (String)e.nextElement();
System.out.println("parm="+parms);
if (parms.contains("delete")) {
recordDelete = true;
Transactions trans =
pm.getObjectById(Transactions.class,
parms.replace("delete", ""));
pm.deletePersistent(trans);
System.out.println("Key=" + parms.replace
("delete", ""));
}
}
4. And, of course, when trying to use getObjectById, that's when the
exception is thrown.
I'm hoping someone can comment on this. I'm sure it's an easy fix to
get around the problem... some little thing I'm just not seeing.

I figured I was - "parms.replace("delete",""))" - if the key is an
unencrypted string, I though I could just pass it in...

[appengine-java] javax.jdo.JDOObjectNotFoundException: Could not retrieve entity of kind Transactions with key Transactions(Transactions(67))
I'm trying to delete a record and having some trouble. When a delete
button is pushed on a jsp, the key associated with the delete button
is being passed to a servlet (the delete button is attached to a list
of Transactions). But, I get an exception on this code:
Transactions trans = pm.getObjectById(Transactions.class, parms.replace
("delete", ""));
pm.deletePersistent(trans);
Not sure what I'm missing here...
