I have a problem in using of my own Database server with Google web application.
Am using eclips (java EE IDE), installed all google plugins init, and develop a sample google web aplication , deployed it into web.Its working correctly.
Now i want to use my own Database in my app.(MYSQL installed in localhost).
Here am using Hibernate to connect with database. All required jar file are placed in lib directory which is in WEB-INF folder.
When i run my application it gives an error like ..

INFO: cleaning up connection pool: null
Please give any Idea to achieve this one....
Do you use Hibernate 4.3.1 Final ?
Hibernate's DriverManagerConnectionProvider tries to create new Threads, which is not allowed on GAE. I also had this issue.
Checking out Google's example on GitHub told me that using Hibernate 4.2.0.Final works fine. I tried to run the same example with Hibernate 4.3.1 and got the same Exception. But with 4.2 it's running just as expected.
I'm gonna downgrade Hibernate in my App and see..
This week i tried to use Hibernate 4.3.6.Final in a Google App Engine / Google Cloud Sql project and ran into the above described problem (java.security.AccessControlException). In earlier GAE/GCS projects i used Hibernate 4.3.0.Beta3 without any problems.
As Gaël Oberson already stated above, the problem is the new implementation of the default connection pool DriverManagerConnectionProviderImpl in Hibernate. This connection pool tries to spawn new Threads with Executors.newSingleThreadScheduledExecutor;
executorService = Executors.newSingleThreadScheduledExecutor();
executorService.scheduleWithFixedDelay(
new Runnable() {...}
This is not allowed on Google App Engine;
A Java application can create a new thread, but there are some
restrictions on how to do it. These threads can't "outlive" the
request that creates them.
The actual problem is the Hibernate configuration which doesn't allow the use of no connection pool. According to Google this connection pool is even not necessary on GAE/GCS;
How to best manage your database connections depends on your use case.
For example, if the time to create a new database connection is
greater than checking and reusing an existing connection, then we
recommend you use connection pooling. Conversely, if the time to
create a new connection is about the same as testing if an existing
connection is alive and reusing it, then we recommend that you create
a new connection to service each HTTP request, and reuse it for the
duration of the request. In particular, the latter case may apply when
you connect from Google App Engine to Google Cloud SQL.
summarized; we don't need connection pooling on GAE/GCS, but Hibernate doesn't provide a non connection pooling option out of the box.
Because of a tight schedule i went for a quick solution; i wrote my own version of DriverManagerConnectionProviderImpl. This version doesn't keep an administration of connections but just opens and closes connection on a call. There's some room for improvement because i should reuse the connection for the duration of the request ... Another solution would be the use of approved GAE Threads...
In my opinion Hibernate should provide the no pooling option for GAE/GCS developers. I already posted this topic at the Hibernate Community.
Follow this:
Appengine has their own version of MySQL called Cloud SQL. See the docs on how to use your own MySQL instance during development. Note that you can not use your own MySQL in production.
See the docs on how make Cloud SQL work with Hibernate.
I got the same exception while trying to use Class.forName("com.mysql.jdbc.Driver"); and got it solved by doing the following:
used com.google.appengine.api.rdbms.AppEngineDriver instead of com.mysql.jdbc.Driver
changed the jdk version from jdk1.7.0_25 to jdk1.7.0_21

I am implementing RESTful web services for our app engine project,In my project we have to access external Mysql instance from google app engine app ,while searching for solution of this problem (searching on SO)i came to know that i have implement web services.
I followed tutorial given on this link to create RESTful web services using jersey and try to communicate with local MySql instance.
Below image displays file stracture of my app engine application
and lib folder which contains all .jar files
My app engine application(in eclipse file >> new >> others >> google >>web application project) is running fine,running project locally(development mode) it takes me to log in page(tutorial takes username and password from html form).
when i press submit button it shows me page not found , when i looked at the stacktrace in the console

by looking at the stack trace it seem that there is problem while making connection to local MySql instance
can some one please helps me to understand ,
1>> what is the reason behind occurrence of this type of error?
2>> how to solve this error?
thanks in advance!!!!!
This mostly happens when you are accessing a class which is not allowed by GAE. This particular error can make you pull your hair all around :)
Always check with GAE before using a new library. Links are given below.
Jersey,
Version 1.5 and 1.1.5 are compatible, but need tweaks.
1.1.5 is semi compatible
Older versions are not compatible. You seem to be using 1.0.3.
Whenever you get ExceptionInInitializerError caused by AccessControlException, the top two reasons are:
You are using an unsupported library. Check with GAE Will It Play With Java.
You are using an blacklisted class. Check with GAE White List.
So, please change your jersey version and make required code changes. This error will go away.

Whereas in jobtracker::50030/machines.jsp?type=active all tasktrackers are showed in running state.
Hadoop Version: Hadoop 2.0.0-cdh4.6.0 and java version: "1.7.0_55"
My jobtracker/tasktracker everything is working fine but I am unable to access jobtracker's web homepage. Similarly in hbase I am getting this exception on every command run, but hbase is working fine.
hbase(main):003:0> list

Any suggestions please.
Fixed this issue actually while installing java I downloaded floatingdecimal.jar manually from maven repository which was causing issue. After deleting jar not only jobtracker issue is resolved but also hbase exception is removed.
Everytime I launch my app I get the "RequestFactory Validation Tool must be run..." error even if listEmptyBoxes() is not executed. I already have file requestfactory-apt-2.5.0-rc1.jar on the annotation processing.

From GWT 2.4, RequestFactory interfaces must be validated. So, have you carefully followed the instructions? There you can find Eclipse/IntelliJ as well as Maven/Ant command line steps (checkout also in the comments).
The output of the validation tool is a class file called "YourRequestFactoryName"DeobfuscatorBuilder.class and is generated in the WEB-INF/classes directory, alongside "YourRequestFactoryName".class. So check for its presence and you'll be sure the validation tool has run (or remove it to be sure it will have to run).
The instruction now seems pretty old. To run RequestFactory ValidationTool with the latest maven-compiler-plugin 3.*:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.1</version>
<configuration>
<forceJavacCompilerUse>true</forceJavacCompilerUse>
</configuration>
<dependencies>
<dependency>
<groupId>com.google.web.bindery</groupId>
<artifactId>requestfactory-apt</artifactId>
<version>2.6.1</version>
</dependency>
</dependencies>
</plugin>
I'm working on reading a zip file stored in a Google Cloud Storage bucket from a Google App Engine application, using the Google Cloud Storage Java API.
It's work fine for small files, but when I try to read the real file I need (25Mb compressed) I get a ApplicationError: 10 exception. The tests are done the application deployed on GAE.
I may have understand that ApplicationError: 10 is thrown when the file is opened for too long (+ than 30s) see : https://groups.google.com/forum/?fromgroups#!topic/google-appengine-java/5XBVaVDKvvs, but I'm still struggling to get this thing work.
Thanks for your help.
There is the testing code I used :
FileService fileService = FileServiceFactory.getFileService();
AppEngineFile readableFile = new AppEngineFile("/gs/xxxx-my-bucket/xxx-bigfile.zip");
FileReadChannel readChannel = fileService.openReadChannel(readableFile, false);
ZipInputStream zis = new ZipInputStream(Channels.newInputStream(readChannel));
ZipEntry ze = null;
while ((ze = zis.getNextEntry()) != null) {
resp.getOutputStream().println("Unzipping " + ze.getName());
for (int c = zis.read(); c != -1; c = zis.read()) {
resp.getOutputStream().print((char) c);
}
zis.closeEntry();
}
zis.close();
The stacktrace I get is :

OK, when working with google app engine and google cloud store, your are bound to several time constraints :
30s to read a file on GS.
10s when using GAE URLFetch service
60s for every request on GAE.
There is no way I can work around those limits in my particular situation.
I recently removed all scriptlets on my project as advised by this post. But now, if I try and make a change to one of my views, I get a deferredExpression error. To get rid of the error, I simply have to terminate, then restart the project.
What is going on here? Is eclipse not able to compile jstl on the fly? Is there something I can change so I don't have to redeploy every time I make a change?

Your classpath is polluted with different JSTL implementation versions. This particular exception means that you've both the jstl-1.2.jar file of JSTL 1.2 and the standard.jar file of JSTL 1.1 or 1.0 in the classpath. This field is introduced in JSTL 1.2 and the ForEachSupport class is present in the both JAR files. Apparently at some point the one of standard.jar is been loaded and used while still having the JSTL 1.2 API in JVM memory.
The solution is to remove the standard.jar. You don't need it for JSTL 1.2 at all.
See also:
Our JSTL wiki page (to learn about what JARs you need)
Update: as per the comments, you actually need to remove the jstl-1.2.jar as well, because the Servlet 2.5 compatible version of GAE/Jetty apparently already ships with JSTL 1.1 out the box. This was conflicting with JSTL 1.2. in your webapp.
You most likely have two versions of JSTL (javax.servlet:jstl:). Remove the older version and make sure you update the version everywhere you were using the older one, and you should be good.
