[appengine-java] email templating
Does anyone have any recommendations for an emailing template solution? Ideally I'd like to be able to define my HTML emails like JSP and then just substitute in the values. I've come across Velocity and StringTemplate, I'd like something thats really lightweight, simple, fast and easy to you. thanks. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: appcfg bulkuploading null key values from csv
I can answer to myself:
Modify the config.yml to:
- kind: Callerid
connector: csv
connector_options:
property_map:
- property: __key__
external_name: key
export_transform: transform.key_id_or_name_as_string
- property: queue
external_name: queue
import_transform:
transform.none_if_empty(transform.create_foreign_key('Queue'))
export_transform: transform.key_id_or_name_as_string
- property: num
external_name: num

By the way, i can entry a new entity via the admin site, with null

What is wrong? how can i upload null values?

[appengine-java] Re: How to close an object before second transaction?
Be sure also that modifyObject does not make indirectly calls to datastore. It was the case in one of my handlers, where the call to modify checked users authorizations, and those were occasionally read from datastore when memcache expired.

I'm glad that you have fixed your problem. I made the decision very early on to detach everything always (unless I was actually in the middle of persisting data within a method).

[appengine-java] Re: How to upload primary key as an id instead of name
Let me explain once again if I missed something earlier. I have an
existing task management application wants to shift it now to google
app engine. While I tried porting my existing data into google app
engine using BulkLoader 1.3.5 with csv file, all my IDs saved as
string (not as long). Suppose I was having a user with id=1 (long), it
uploaded into google app engine with name=1(String). Now when I am
saving new records directly on google app engine using my application
running on google app engine, it saves an another record with
id=1(this time it's long). So it's not possible for me to identifiy b/
w these two records (one with id=1 another with name=1).
I hope a lot of people are using BulkLoader API for uploading existing
data to GAE Google also recommend this API, so it should not have
such a basic bug at this level.
Any help/suggestion in this regard will be highly appreciated

You can do this now using the RemoteDatastore Java utility

For example, this code runs on your desktop and creates a single

RemoteDatastore.install();
RemoteDatastore.divert(http://myVersion.latest.myApp.appspot.com/remote-datastore

// create an entity with a numeric key
Key key = KeyFactory.createKey(MyKindName, 35);
Entity entity1 = new Entity(key);
entity1.setProperty(property1, hello);

Due to uploaded data with name=keyvalue, when I am try to get Key

Cool, if you structure your entity class like this though:
class Entity {
ListString tags;

how are you going to query which Entity instances match a given tag? I think
that all the tags need to be indexed so your query statement can find them -
I'm not 100% sure on this, if you can somehow match on that ListString,
that would be new to me! I was thinking you might have to decide how many
tags an Entity can have, and explicitly declare each like:
class Entity {
String tag1, tag2, tag3;
String foo;
}
only the first tag is required, the other two can be null. Then your query
statement would have to be something like:
select from Entity where tag1 == 'cow' || tag2 == 'cow' || tag3 ==
'cow';
not sure if there's a better way to do it, let us know what you try because
this is probably a pattern that can be reused for others wanting to do the

Mark,
Thanks very much for this - it's useful. I'm slowly getting used to
this non-relational way of thinking.
The count of the tags doesn't need to be 100% accurate, as it will
only be used to approximate how many entries exist for a given tag -
the tag cloud aim is to show tags associated with many entities in a
larger font and tags associated with fewer entities in a smaller
font. If the insert, update or delete of Entity succeeds and gets
committed, but the persistence action against the TagCounter fails in
a few instances that would not be a big deal.
I'll probably allow three tags per Entity, so was planning on:
class Entity {
ListString tags;
String foo;
}
for flexibility in of the number of tags.
So when inserting a new entity I would need to:
Create Entity
For each tag in Entity select TagCounter
If tag counter exists for tag increment count by 1
If tag counter does not exist for tag create TagCounter with count of
1
When deleting an entity I would need to:
For each tag in Entity select TagCounter
Decrease count by 1 of TagCounter
Delete Entity
This sounds ok to me. When a user clicks a tag the query is simple
too.
I'll give this a try and see how it looks.
Thanks again.

I probably have a naive understanding of what you're doing, maybe
explain a little more, but to me it looks like this:
class TagCounter {
int count;
String label; // primary key, unique tag name.
}
class Entity {
String tag;
String foo;
}
whenever the user creates a new entity, record its tag(s), then
increment the appropriate TagCounter instance. Keeping counters like
this introduces a bottleneck and goes against what you want to be
doing for a highly scalable web service, so you may want to shard them
(imagine you have thousands of users all trying to increment a single
tag counter at once). Since the above two classes won't be in the
same entity group, you wouldn't be able to perform both operations in
a single transaction. You can either accept the fact that your tag
count may be out of sync with the actual number of entities with that
tag, or you can have a multistep process and clean up dangling tag
counts with a task (eventual consistency might be the term here). I'm
referring to Nick Johnson's article on distributed transactions which
I think you can modify to do what you're looking for:
http://blog.notdot.net/2009/9/Distributed-Transactions-on-App-Engine
I'm still learning app engine so take the above with a big grain of
salt. To me, it seems that if you want to write a highly scalable web
service, you need to accept that you may lose some data precision, or
you have to put in additional work to get what you want (compared to
assuming a single mysql instance etc).
Anyway, after you implement something like the above, your original
two queries should be easy to do. You probably want to define how many
tags an Entity can have. If an Entity can have more than one tag, I'd
explicitly state what that max is. Write out everything you need when
the user submits an entity, so that your reads will be fast as other
users browse the site.

I have an existing task management application wants to shift it now to google app engine. While I tried porting my existing data into google app engine using BulkLoader 1.3.5 with csv file, all my IDs saved as string (not as long). Suppose I was having a user with id=1 (long), it uploaded into google app engine with name=1(String). Now when I am saving new records directly on google app engine using my application running on google app engine, it saves an another record with id=1(this time it's long). So it's not possible for me to identifiy b/ w these two records (one with id=1 another with name=1). If you want to use names you have to put some logic in your app and create them also for new objects before saving. Otherwise if all your existing ids are numeric you can change bulkloader to create the id instead of name.

[appengine-java] Google App Engine problem with receiving OPTIONS requests
Hey, I have a rather problematic issue with App Engine when attempting to post data to the server. Firefox uses OPTIONS method to verify the data before sending it to the server and this is causing the issue. Everything works fine on localhost and the server receives the OPTIONS request, returns 200 and everything goes fine. But when I put it to production I get the following error when trying to post data: java.security.AccessControlException: access denied (java.lang.RuntimePermission accessDeclaredMembers) at java.security.AccessControlContext.checkPermission(AccessControlContext.java: 355) at java.security.AccessController.checkPermission(AccessController.java: 567) at java.lang.SecurityManager.checkPermission(Unknown Source) at com.google.apphosting.runtime.security.CustomSecurityManager.checkPermission(CustomSecurityManager.java: 45) at java.lang.SecurityManager.checkMemberAccess(Unknown Source) at java.lang.Class.checkMemberAccess(Unknown Source) at java.lang.Class.getDeclaredMethods(Unknown Source) at javax.servlet.http.HttpServlet.getAllDeclaredMethods(HttpServlet.java: 479) at javax.servlet.http.HttpServlet.getAllDeclaredMethods(HttpServlet.java: 478) at javax.servlet.http.HttpServlet.getAllDeclaredMethods(HttpServlet.java: 478) at javax.servlet.http.HttpServlet.doOptions(HttpServlet.java:534) at org.springframework.web.servlet.FrameworkServlet.doOptions(FrameworkServlet.java: 594) at javax.servlet.http.HttpServlet.service(HttpServlet.java:722) at javax.servlet.http.HttpServlet.service(HttpServlet.java:806) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java: 511) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1166) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:343) at org.springframework.security.web.access.intercept.FilterSecurityInterceptor.invoke(FilterSecurityInterceptor.java: 109) at org.springframework.security.web.access.intercept.FilterSecurityInterceptor.doFilter(FilterSecurityInterceptor.java: 83) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.access.ExceptionTranslationFilter.doFilter(ExceptionTranslationFilter.java: 97) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.authentication.AnonymousAuthenticationFilter.doFilter(AnonymousAuthenticationFilter.java: 78) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.authentication.AbstractAuthenticationProcessingFilter.doFilter(AbstractAuthenticationProcessingFilter.java: 187) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.authentication.logout.LogoutFilter.doFilter(LogoutFilter.java: 105) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.context.SecurityContextPersistenceFilter.doFilter(SecurityContextPersistenceFilter.java: 79) at org.springframework.security.web.FilterChainProxy $VirtualFilterChain.doFilter(FilterChainProxy.java:355) at org.springframework.security.web.FilterChainProxy.doFilter(FilterChainProxy.java: 149) at org.springframework.web.filter.DelegatingFilterProxy.invokeDelegate(DelegatingFilterProxy.java: 237) at org.springframework.web.filter.DelegatingFilterProxy.doFilter(DelegatingFilterProxy.java: 167) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java: 88) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java: 76) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.ParseBlobUploadFilter.doFilter(ParseBlobUploadFilter.java: 97) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.runtime.jetty.SaveSessionFilter.doFilter(SaveSessionFilter.java: 35) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at com.google.apphosting.utils.servlet.TransactionCleanupFilter.doFilter(TransactionCleanupFilter.java: 43) at org.mortbay.jetty.servlet.ServletHandler $CachedChain.doFilter(ServletHandler.java:1157) at

[appengine-java] Re: email templating
For very simple templates you can use java.text.MessageFormat. It lacks the ability to do real template work, conditions, loops, HTML escaping etc, but for simple substitutions, numbers, dates, etc it works. There may be a comparable and better implementation in one of the apache utility packages as far as I remember. Velocity is a big hammer, but it is a fully featured template language. Complicated to integrate if you do not use it they way they thought you would (web pages with predefined templates, like JSP). -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] new demo shows google appengine instances registering in opscode chef upon startup
I wrote a demo application which registers google appengine instances in chef [1], specifically the opscode platformhttps://cookbooks.opscode.com/users/new, upon startup. While the chef api is not 100% complete in jclouds, enough is finished to start integrating. http://github.com/jclouds/jclouds-chef-googleappengine-demo The status page shows all the instances of the current google app engine application, which are registered in the opscode platform. http://jclouds-chef-demo.appspot.com/nodes/status.check When this seems to hesitate, it is probably google firing up a new instance, which implies a new node registration. This is a simple demonstration. More sophisticated applications can be built to use the databag concept in chef to ensure that all dots between your cloud and non-cloud infrastructure are connected [2]. You could even use the jclouds compute api to launch new compute nodes (ex. ec2) and register them accordingly. This demo requires a publicly available Chef 0.9.6 endpoint. If you are using the Opscode Platform, remember that you get 5 nodes for free. Make sure you clean up your nodes in the console when you are finished testing [3].

[appengine-java] Problem of persistence in JDO
Hi! I have a problem with active transaction.When I try to guard in
the datastore, says:
Object with id com.google.appengine.api.datastore.Key:Torneo(1)/
Equipo(3) is managed by a different Object Manager.
Disegn:
A Torneo has relation one to many Equipo
A Fecha has relation one to many Partido
The method:
private static PersistenceManager pm =
PMF.get().getPersistenceManager();
//pm is a singleton
public void crearPartido(Long idEqLocal, Long idEqVisitante, Date
fecha,
Fecha fechaAgreg, String resultado, String
hora,Long idTorneo){
PersistenceManager pm =
JDOHelper.getPersistenceManager(fechaAgreg);
//or Transaction tx = pm.currentTransaction();
Transaction tx = pm.currentTransaction();
try {
tx.begin();
Partido par1 = null;
ControladorTorneo cT= new ControladorTorneo();
par1 = new Partido(null, new
Resultado(),cT.devolverEquipo( idTorneo,idEqLocal),
cT.devolverEquipo(idTorneo,idEqVisitante), fecha, hora);
/*In mode debug, is here below where accedes for the
block finally(with error) */
fechaAgreg.agregarPartido(par1);
pm.makePersistent(fechaAgreg);
tx.commit();
} finally {
if (tx != null tx.isActive())
tx.rollback();
pm.close();
}
}
And the method crearPartido is called for:
public String execute() throws Exception {
ControladorFecha cF = new ControladorFecha();
Fecha fechaSel = cF.devolverFecha(fecha, torParam);
ControladorPartido cP= new ControladorPartido();
cP.crearPartido(idEquipoLocal, idEquipoVisitante,
fechaPartido,fechaSel,resultado,hora,torParam);
return SUCCESS;
}
Thr method devolverFecha:
private static PersistenceManager pm =
PMF.get().getPersistenceManager();
//pm is a singleton
public Fecha devolverFecha(Long idFecha, Long torneo) {
Transaction tx = pm.currentTransaction();
try {
tx.begin();
Key k2 = new
KeyFactory.Builder(Torneo.class.getSimpleName(),
torneo).addChild(Fecha.class.getSimpleName(), idFecha)
.getKey();
Fecha f = pm.getObjectById(Fecha.class, k2);
tx.commit();
return f;
} finally {
if (tx.isActive()) {
tx.rollback();
}
//pm.close();
}
}

So it's not possible for me to identifiy b/ w these two records (one withid=1 another withname=1). If you want to use names you have to put some logic in your app and create them also for new objects before saving. Otherwise if all your existing ids are numeric you can change bulkloader to create theidinstead ofname. I think gae behavior is clear, simple and consistent. cheers Uberto -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] limit on the entities in the entitygroup
Hello, I am writing a multi-tenant accounting app for SMB's. Is there any limit on the number of entities in the entitygroup? I am planning to put most of the entities in one entity group for each tenant. Since my app is for SMB's, the number of concurrent users is 3-5. Hence, I don't anticipate the loss of concurrency, even if I put most of the entities for each tenant in the same entitygroup. Any suggestions -Aswath -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Please help, I'm not able to obtain the oAuth redirect URL from twitter
Sorry to hear of your trouble Nischal I'm hitting twitter without any issue from my prod app engine - if it helps, i've had a lot of success using twitter4j libraries - maybe you can check them out. The only strange thing about getting an auth token from twitter oauth from app engine is how you have to direct the user to the authorization url and hold the token in your session on the server side while they authorize the app - then continue with the process of getting an oauth token on the server.

@Benjamin I am using twitter4j. Its not an issue on my end since the apps been running from 6 months now. And I just ran a check on many other twitter apps hosted on the app engine, none seem to be working. Can you share the url of your app? -Nischal On Jul 23, 10:03 am, Benjamin bsaut...@gmail.com wrote: Sorry to hear of your trouble Nischal I'm hitting twitter without any issue from my prod app engine - if it helps, i've had a lot of success using twitter4j libraries - maybe you can check them out.
