Hello, You may find something usefull here: http://stackoverflow.com/questions/3278900/httpservletrequest-setcharacterencoding-seems-to-do-nothing. I suggest you to try setting the encoding of the request prior to processing any information, it may works for the query string too.

[appengine-java] 200 was logged when, apparently, an error happened
Dear App Engine developers and googlers, Sorry for the long post, but I got something weird on my logs. A response status 200 was logged when, apparently, an error happened. Does it makes any sense, or I'm just misreading the messages from the logs? This happened a few times, and some requests are failing properly (500 status). Is this due the static 500 error handler configured in my appengie-web.xml? In this case, I guess that this is not a sucessfull request either, so a 500 error is more applicable and I'll get this warning on my error chart in the dashboard (which I'm not sure now that is providing the right information ...).

Re: [appengine-java] Re: 200 was logged when, apparently, an error happened
Thaks for your answers Mat. I guess you may be right. The log for the serious problem is before the sucesfull request. I'll double check our initialization code, but on local server all our developers are running and debugging the app properly, so it may be a singular initialization problem that may be happening only in production. I'll try starting the devserver and, immediately after the app is initialized, access the erroring servlet to see if I find something diferent. When testing, we usually access the index.jsp url at first run of the local instance, so there may be something wrong in the servlet/jsp that is erroring. I'll post back soon.

Hi Miguel, The MutationPool is managed by the MapReduceServlet, and thus, if you don't use it inside a MapReduce job it won't be flushed to the datastore automaticaly. You can, however, use the pool and manage it by your own. You can also grab the code and build a custom version of it, too.

[appengine-java] Re: Change from String to Integer , now can't rid of Zombie instances... what is the right procedure to do so?
Daniel,
To convert old session data I started to persist just the user Id in
session. Sadly, unlike memcache, you can't control how the session is
deserialized. In my case, any request with has the old user data in session
was throwing 500 erros and I couldn't control this behavior (it was a
filter from the gae...). What I did was something like this:
public MyUser getCurrentUser(HttpServletRequest req) {
Object userOrId = req.getSession().getAttribute(user);
if (userOrId instanceof Long) {
return loadUserFromDsOrMemcache((Long) userOrId);
} else {
// Remove user from session and start storing ID for next change to
User class dont raise exceptoins ...
User user = (User) userOrId;
req.getSession().setAttribute(user, user.getId());
return user;
}
}
This way I could get rid of storing this in session and of the app being
unacessible when I changed my model (wich was happening heavly by the
way...). Note that at the time I deployed this code, the User object hasn't
changed.
After running this for a while (you can expire sessions or delete them in
bulk from the datastore so you can force them to expire, I deployed the new
version.
To store json data, you may use some json library that can map/convert
to/from Java - Json, like Google Gson:
String userJson = new Gson().toJson(user);
req.getSession().setAttribute(user, userJson);
(...)
String userJson = (String) req.getSession().getAttribute(user);
if (userJson != null) {
User user = new Gson().fromJson(User.class, userJson);
}
This way you can add/remove fields to you model, and old session data will
be restored as expected. Note that is a good practice to set defaults for
the new fields, so your session data won't create unusable objects. In your
original post, the change from string to integer may be solved by
overriding the Gson de-serializer to handle the id field as number and not
as string. I guess that you can change the way Java will de-serialize your
classes too, but I'm not sure if this will solve your particular issue
mentioned.
Not sure if this is the best way to handle, but this is how I solved on our
live app.
More on Gson: http://code.google.com/p/google-gson/.
Hope this helps (sorry for some typos or misspelled words)
Best Regards,
-Ronoaldo

[appengine-java] Re: Change from String to Integer , now can't rid of Zombie instances... what is the right procedure to do so?
Sine you are talking about _ah_SESSION stuff I suppose you are serializing ToBuyBeans to the sessions. On AppEngine, sessions are implemented using a combination of datastore and memecache. When you deleted your old session data from the datastore, the memcache was still there, and only when they got flushed your problem was automatic solved. Sadly, I was having this trouble too previously, and the only way to get rid of it was to deploy a versions that was trying to fetch data from session and convert to new format or invalidate the session. This is very odd, tought, so I started to store only unchanged data, like a JSON representation of you objects, that will never stop your app when you change your code and redeploy. Gson and flex-json are good start points, apart from the fact that they add some small conversion overhead before store data in session. Hope this helps (sorry for typos ...

I'm experiencing the same behavior in my app. I got the 404 infinite redirect loop when my app has a jsp-config in web.xml. This only happens on production, so I guess is this a production bug?

[appengine-java] Re: Automatically increment version number
I use Mercurial as SCM, and the command hg id -i and hg id -n give's me the
current revision id and hash. To be able to have full control on what
version is running on the server side, we use the following ant tasks:
This one filter an appengine-web.xml.in file, that is under version
control, and that has the appid and appversion as ant filter properties:
target name=update-app-version description=Update the appengine-web.xml
with the current mercurial revision as app version
exec executable=hg outputproperty=mercurial.changeset
arg value=id /
arg value=-i /
/exec
exec executable=hg outputproperty=mercurial.revision
arg value=id /
arg value=-n /
/exec
property name=appversion
value=${version}-${release}-${mercurial.revision}-${mercurial.changeset}-${stability}
/
filter token=appid value=${appid} /
filter token=appversion value=${appversion} /
copy file=war/WEB-INF/appengine-web.xml.in
tofile=war/WEB-INF/appengine-web.xml filtering=true overwrite=true /
echo message=App version set to ${appversion} /
/target
And this is a modified version of the one that comes with the SDK who lets
you set a system property as your password, giving you an automated
deployment, if needed (like let's your CI sistem deploy new versions
periodicaly):
target name=deploy depends=update-app-version description=Uploads the
application to App Engine.
java classname=com.google.appengine.tools.admin.AppCfg fork=true
inputstring=${deploy.password} failonerror=true
classpath
path location=${appengine.tools.classpath} /
path refid=project.classpath /
/classpath
arg value=--email=${deploy.email} /
arg value=--passin /
arg value=update /
arg value=war /
/java
/target
Just set the deploy.email and deploy.password properties either on a
file at your home directory or as a command line argument. In our build
file, we set the appid and base versions as properties too, giving you full
control when deploying while keeping the defaults to make things easier.
Hope this helps.

When using the java.net.URLConnection, you cant set the timeout over the 10s. You must use the Low Leve URLFetchService and URLRequest classes to be able to set higher timeouts.

[appengine-java] Re: req.getparamater non-latin character problem.
I guess you have to do the following in order to have the proper encoding
when retrieving the request:
if (request.getCharacterEncoding() == null)
try {
request.setCharacterEncoding(ISO-8859-1);
} catch (UnsupportedEncodingException e) {
}
Then, further calls to request.getParameter(kimeisim) will be properly
converted and available as the respective UTF-8 strings.
Hope this helps

[appengine-java] Re: Why do I get - The datastore operation timed out, or the data was temporarily unavailable.
Sorry if I'm wrong, but I guess that this is the same problem I was facing a few days ago. I solved my problem using a *batch size*, and iterating until the batch size limit. The JDO iterator is using the same datastore operation, and thus have a time limit to perform your query. Your loop is issuing other operations (the delete() method) that is making your it.next() fails event if there are small datasets. I've read from other threads that the deletes are even expensive than the writes. Try this one: fetch all keys first, then loop over them. If you call size() from the returned List, it will fetch all keys. Be carefull to set a reasonable resultset limit: I guess that a 10k betch size is good for your query, at least on my results. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: startup errors while using RemoteApiInstaller
You can't put the remote api jar in your web app classpath. The Remote API is intended to use on a normal Java Application. All you need on your web app is to map a servlet that comes with the sdk on your web apphttp://code.google.com/intl/en/appengine/docs/java/tools/remoteapi.html#Configuring_Remote_API_on_the_Server, and then create a separete client application to use the Remote API. One option (that I'm using on a project) is to create a separate source folder in your Eclipse project, and then configure the build path to make the compiled classes go out of your web-app classpath, and to put the required libraries for your remote-api application on a separate lib folder, something like this: src/ - Your web-app source folder remote/ - Your remote-api source folder lib/ - The libraries you don't want to be on the web-app classpath. The test libraries and remote-api libraries, for example. war/WEB-INF/lib - The libraries that your app needs for runtime only (make sure they all are appengine-safe) You can put your jars on those folders, and then add them to the build path.

[appengine-java] Re: Can only reference properties of a sub-object if the sub-object is embedded
Hello kidowell, It looks like you are trying to do som kind of *join like* sintax here, since you are trying to fetch parent Entities based on a property on the child ones (or vice-versa). In your case, the mapping is telling to the AppEngine underlying datastore to store the Key of the Annotation under the key of the AnnotationType. The AppEngine datastore is not a regular Relational datastore, and JDO/JPA don't work as you expect it to work if you are not familiar with this kind of datastore. I suggest you to read a bit more on the first chapters of the current documentation that explain how the datastore works, and then you may understand better how you will model your data to archive your queries. Also, i suggest you to consider using another persistence layer on your app so you can make better usage of the datastore resources. Currently, we are changing our live web app to Objectify, leaving all headheches that comes with JPA on AppEngine...

Re: [appengine-java] Re: JPA/JDO vs low level API
As Jeff and others already posted, JPA on AppEngine just don't work as you expect (from the JPA point of view), and others just work as you don't. I'm the team leader of a running GAE/J application and we are, like Jeff says, * screaming* because of my decision to use JPA. We were about to consider using JDO, due to it's non-RDBMS options, but looks like the best choice is another tool like Objectify or Twig-persist. We are now trying out those tools to do come poof-of-concept in our codebase. A good choice is to encapsulate your datastore using a DAO or Repository pattern (or even both!), since they may help you to change your mind in the future. We did it and now we can try out some other tools on top of the Low Level API. In regards of the Objectify library, +1 for the helpers on schema migration. This is very (very!) hard to acomplish on a real-world web app when using JDO/JPA, and is a very usefull feature. In any case, now the RemoteApi is also available in Java (as per 1.4.4) and this is very useful to do some data export, local fixture loading and others. So, it is nice to at least know how the datastore works, it may help you in the future. -- You received this message because you are subscribed to the Google Groups Google App Engine for Java group.

[appengine-java] Re: Bundling app with jsp into a jar (to be reused insied another app)
Hi GervalsB, I'm not sure about jsps, but I do know that you can build a jar with your classes, servlets and other java resources, and you can map them on web.xml even if they aren't in your source folder. The jar only need to be under war/WEB-INF/lib. In this case, I'll suggest you to put the jar bundled in a zip, alongside with any static resource, and use a configurable property on your servlet config, to allow you to reuse your code on a new project by droping the jar + unpacking the zip and then setting up your servlet urls. If you plan to build something packaged inside the jar, I'll suggest a template engine like Velocity, that will allow you to embed the templates in the jar, but if you have any css or other stuff that need to be public, you still need to put them under the public war directory to allow appengine to recognize them as static resources.

[appengine-java] Embeded + Related list raises IllegalArgumentException: out of field index: -1
Sorry if it is a duplicate, but I coudn't find any solutions for this
problem. I'm not sure if someone else solved this, and any help would be
very helpfull.
This seems like those rare corner cases, but it happened:
Using this data models:
@Entity
public class Parent {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Extension(vendorName = datanucleus, key = gae.encoded-pk, value =
true)
private String key;

private ListChild relatedChilds = new ArrayListChild();
@Embedded
private InlineChild inlineChild;
public ListChild getRelatedChilds() {
return relatedChilds;
}
public void setRelatedChilds(ListChild relatedChilds) {
this.relatedChilds = relatedChilds;
}
public InlineChild getInlineChild() {
return inlineChild;
}
public void setInlineChild(InlineChild inlineChild) {
this.inlineChild = inlineChild;
}
public String getKey() {
return key;
}
public Long getId() {
return id;
}
}
@Entity
public class Child {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
@Extension(vendorName = datanucleus, key = gae.encoded-pk, value =
true)
private String key;
@Extension(vendorName = datanucleus, key = gae.pk-id, value =
true)
private Long id;
private String name;
@SuppressWarnings(unused)
@OneToMany
private Parent parent;
public Child(Parent parent) {
this.parent = parent;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getKey() {
return key;
}
public Long getId() {
return id;
}
}
@Embeddable
public class InlineChild {
private String name;
private Date creationDate;
private ListString urls;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}

this.creationDate = creationDate;
}
public ListString getUrls() {
return urls;
}
public void setUrls(ListString urls) {
this.urls = urls;
}
}
And this JUnit test case fails for the test #3:
public class OutOfIndexTest {
LocalServiceTestHelper helper = new LocalServiceTestHelper(
new LocalDatastoreServiceTestConfig());
@Before
public void setUp() throws Exception {
helper.setUp();
}
@After
public void tearDown() throws Exception {

}

EntityManager em = EMF.get().createEntityManager();
Parent p = new Parent();
p.getRelatedChilds().add(new Child(p));
em.persist(p);
em.close();
}
@Test
public void testPersistParentWithAllChilds() {
// This test fails, but only if the embeded has a list.
EntityManager em = EMF.get().createEntityManager();
Parent p = new Parent();
p.getRelatedChilds().add(new Child(p));
p.setInlineChild(new InlineChild());
em.persist(p);
em.close();
}
@Test
public void testAddEmbededAfterPersistAllChilds() {

}
}
