I'm trying to write to cloud bigtable in my app engine servlet. I copied the BigTableHelper from https://github.com/GoogleCloudPlatform/cloud-bigtable-examples/blob/master/java/managed-vm-gae/gae-bigtable-hello/src/main/java/com.example.cloud.bigtable.helloworld/BigtableHelper.java, and in my servlet I simply did the following.
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws IOException {
try (Table t = BigtableHelper.getConnection().getTable(BigtableHelper.TEST_TABLE)) {
Put put = new Put(Bytes.toBytes("row1"));
put.addColumn(BigtableHelper.RAW_UPDATE_FAMILY, BigtableHelper.RAW_UPDATE_QUALIFIER,
Bytes.toBytes("testdata"));
t.put(put);
} catch (IOException e) {
log("writeToBigtable", e);
}
}
The put failed with error.

BigtableHelper.getConnection() didn't throw an exception, I assume the it connect successfully. Is there anything wrong with the put statement? What could cause this problem? Thanks!
We have updated examples for interacting with Cloud Bigtable from Google App Engine Flex and Standard using Java 8 here:

This error is thrown when the servlet starts.
It's always the Metrics Module, but the Metrics Module looks correct in terms of injection:
package sc.analysis.metrics;
import com.google.inject.AbstractModule;
import com.google.inject.Singleton;
import com.google.inject.servlet.RequestScoped;
public class MetricsModule extends AbstractModule {
#Override
protected void configure() {
bind(Metrics.class).to(MetricsImpl.class).in(RequestScoped.class);
bind(GlobalMetrics.class).to(GlobalMetricsImpl.class).in(Singleton.class);
requestStaticInjection(StaticMetricsHolder.class);
requestStaticInjection(StaticGlobalMetricsHolder.class);
requestStaticInjection(ScopeSafeMetricsHolder.class);
}
}
None of the other injections seem to have issues; is there sommething I'm missing? I don't know much about guice to be honest, but the code that calls the Metrics (GeoAdminAPI) uses a provider:
public class GeoAdminAPIv2 extends GeoAdminAPI {
#Inject
GeoAdminAPIv2(...,
final Provider<Metrics> metrics,
...)
I'm trying to access graph api. I'm using MSAL4J to access the graph apis. But I'm getting com.microsoft.aad.msal4j.MsalClientException: java.net.SocketTimeoutException: connect timed out even when I'm not using my vpn.

Any help will be appreciated.
Finally, I figured it out. And writing this answer with hope that it will help someone. com.microsoft.aad.msal4j.MsalClientException: java.net.SocketTimeoutException: connect timed out This exception was occurring due to the proxy issues.
My system was behind the proxy so it was not able to connect with microsoftonline servers.
I have two approaches to get the access_token from azure AD.
First Approach
Using REST API provided by AZURE AD
public String getAccessToken() throws UnsupportedOperationException, IOException {
ObjectMapper mapper = new ObjectMapper();
Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("your_proxy_address", your_proxy_port));
OkHttpClient client = new OkHttpClient.Builder().proxy(proxy).build();
MediaType mediaType = MediaType.parse("application/x-www-form-urlencoded");
RequestBody body = RequestBody.create(
"grant_type=client_credentials&client_id=your_client_id&scope=https://graph.microsoft.com/.default&client_secret=your_client_secret",
mediaType);
Request request = new Request.Builder()
.url("https://login.microsoftonline.com/your tenent id/oauth2/v2.0/token")
.method("POST", body).addHeader("Content-Type", "application/x-www-form-urlencoded").build();
Response response = client.newCall(request).execute();
// String token = response.body().string();
return mapper.readTree(response.body().string()).get("access_token").asText();
}
You can get the access_token by using this method. Another approach is, by using the MSAL4J library.
Second approach
First build client object
private static void BuildConfidentialClientObject() throws Exception {
Proxy proxy = AuthProvider.getInstance().getProxy();
app = ConfidentialClientApplication.builder(clientId, ClientCredentialFactory.createFromSecret(secret))
.proxy(proxy).authority(authority).build();
}
Then get the access_token
private static IAuthenticationResult getAccessTokenByClientCredentialGrant() throws Exception {
ClientCredentialParameters clientCredentialParam = ClientCredentialParameters
.builder(Collections.singleton(scope)).build();
CompletableFuture<IAuthenticationResult> future = app.acquireToken(clientCredentialParam);
return future.join();
}
Now you can access the graph APIs using this access_token and complete your tasks.
PS: I'm using demon approach for my tasks. There are different approaches to fulfill your requirements.
You can have a look here for authentication approach reference.
When I shutdown DB after flush() and before commit(), an exception is logged but not captured by the code:
#Stateless
#TransactionAttribute(TransactionAttributeType.NEVER)
public class OuterService {
#EJB InnerService innerService;
public String outerMethod() {
try {
innerService.innerMethod();
return "success";
} catch (Exception e) {
return "failure";
}
}
}
#Stateless
#TransactionAttribute(TransactionAttributeType.REQUIRED)
public class InnerService {
#PersistenceContext EntityManager em;
public void innerMethod() {
em.persist(new Entity());
em.flush();
} //put the breakpoint here
}
I run the code in debug mode and set a breakpoint after flush but before exiting the transactional method. When the execution is paused, I stop the db service and then resume the code.
An exception is logged with the following root cause:
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException:
Communications link failure during commit(). Transaction resolution
unknown.
but it is not captured by the outer try..catch block and the method successfully completes. It seems that JTA implementation suffocates the exception. How can I be notified of an error?
I already tried BMT and CDI events but none worked. Plain JDBC and JPA (Hibernate, with built-in and C3p0 pools) in Java SE environment, however, do work.
My setup: Ubuntu 17.10, Wildfly 10, MySQL 5.7.20, Connector/J 5.1.44

I investigated on this and it sounds to me as an issue. I created the jira here: https://issues.jboss.org/browse/JBTM-2983. Feel free to follow discussion there if it's confirmed so.
I expect the caller should be informed that there was an exception during commit. Btw. in case I of some further investigation I created a small test project based of your issue: https://github.com/ochaloup/catch-ejb-exception-test.git
I'm not sure. There could be several causes.
First I would try is to increase the net_write_timeout property in your mysql configuration.
Also your Exception is caused by error code XAException.XAER_RMFAIL
Jboss Javadoc: XAException:
Error code indicating that the resource manager has failed and is not
available.
So it seems that PersistenceContext is broken or invalid because of break point interruption.
I am using Resteasy 2.3.3, bundled with JBoss-AS-7.1.3. I'm trying to
throw a new WebAppliationException, and the output (to the client) seems
fine, but I'm left with an unwanted stack trace in my log. I have a few
other Exceptions mapped, and I was wondering if the mapping was somehow
causing an issue trying to wrap this Exception.
Simple example:
public class SimpleService {
#GET
#Path("stuff")
public String getStuff(final #QueryParam("param1") String param1,
#QueryParam("param2") String param2) throws ActionException {
if (param1==null && param2==null) {
throw new WebApplicationException();
}
I get the following exception:
[WARN] org.jboss.resteasy.core.SynchronousDispatcher#error - failed to execute: javax.ws.rs.WebApplicationException
Any ideas what this error might mean? How I could get rid of the messages?
I stumbled across another class in the javadoc - NoLogWebApplicationException, and it says:
WebApplicationExceptions are logged by RESTEasy. Use this exception
when you don't want your exception logged
https://docs.jboss.org/resteasy/docs/2.3.3.Final/javadocs/org/jboss/resteasy/spi/NoLogWebApplicationException.html

How can I change the default Port?
Are there any workarounds?
Change the URL you are fetching to include the default port 80. Example: http://www.cnn.com becomes http://www.cnn.com:80. There's also a workaround involving overriding classes but I prefer to clarify the URL.
I had that problem at first (I have a GWT+GAE app) and I was using this very simple code and I got the js cookie exception and the port:-1 exception
WebClient webClient = Holder.get();
HtmlPage page=null;
try {
page = webClient.getPage(url);
System.out.println("CRAWLER DONE");
} catch (FailingHttpStatusCodeException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// appengine hack because it's single threaded
String pageContent = page.asXml();
webClient.closeAllWindows();
return pageContent;
then I tried the following,
webClient.setCssEnabled(false);
webClient.setThrowExceptionOnFailingStatusCode(false);
webClient.setThrowExceptionOnScriptError(false);
And it just miracusly worked. cheers.
