Get absolute URL in Play framework and Secure social - java

I'm using secure social in my Play project. I'm trying to use my own E-Mail for the registaiton process.
The how to is described here:
http://securesocial.ws/guide/views-customization.html
My Problem is, that I get an error when I try to genreate the absoute URL in the template:
#securesocial.controllers.routes.Registration.signUp(mailToken).absoluteURL(IdentityProvider.sslEnabled)
Here ist the Error Log:
[error] play - Cannot invoke the action, eventually got an error:
java.lang.Runt imeException: There is no HTTP Context available from

Does anybody know what the mistake is?


Your template requires implicit request which is mandatory for obtaining an absolute URL.
#(/*template's parameters*/)(implicit request: RequestHeader)
This request must be available in a method which renders the template.


I had a pretty similar error if not the same, probably you're also mixing some java code in your project.
You must create a java context in your controller ( in this case the custom views controller ) for it to be used by the views.
For example:
Scala helper to create a java context
object JavaContext {
import play.mvc.Http
import play.core.j.JavaHelpers
def withContext[Status](block: => Status)(implicit header: RequestHeader): Status = {
try {
Http.Context.current.set(JavaHelpers.createJavaContext(header))
block
}
finally {
Http.Context.current.remove()
}
}
}
Usage:
class CustomSecureSocialTemplates(env:RuntimeEnvironment[_]) extends ViewTemplates.Default(env:RuntimeEnvironment[_])
{
override def getLoginPage(form: Form[(String, String)],
msg: Option[String] = None)(implicit request: RequestHeader, lang: Lang): Html = {
JavaContext.withContext {
views.html.security.login(form,msg)
}
}

fabric8 v6.1.1 Failure at creating Custom Resource with POST call Resulting in Not Found

New to fabric8 K8S client library. Recently was trying to create a custom resource object using fabric8 (v6.1.1) and got Not Found Message at the POST Call internally. Can list on the CRD client on which this POST is performed.

Created a CRD client in code and able to list on it :
MixedOperation<CRD_POJO, KubernetesResourceList<CRD_POJO>, Resource<CRD_POJO>> CRDClient = apiClient.resources(CRD_POJO.class);
System.out.println("CRDclient List:::::" + CRDClient.list());
Till this point it works fine and I am able to list the objects as well but after that created a custom object of type CRD and tried doing a create on the CRD client and it failed with the above error.
CRD_POJO CR = new CRD_POJO();
// Some set operations to make the CR object ready
...
CRD_POJO created = CRDClient.inNamespace("test").createOrReplace(CR);//Here it fails
Anyone faced this or know any solution? Any lead will help to solve this issue

As #RohanKumar pointed, implementing the "Namespaced" interface in this case solved the issue.
#JsonIgnoreProperties(value ={"status"}) #Version("v1") #Group("<resource spec.group>") public class CRD_POJO extends CustomResource<CRD_POJOSpec, CRD_POJOStatus> implements Namespaced { ..... }

Flink FileSync with AWS S3 plugin throw error when accessing S3 access point - "null uri host"

After following this instruction I am able to access the S3 bucket via access point + VPC endpoint perfectly fine from AWS CLI.
Basically I use
s3://arn:aws:s3:ap-southeast-1:<account number>:accesspoint/<bucket name>
the same way as I use
s3://<bucket name>
All aws s3 ... commands works great.
However that's not the case for my my Java based Flink project code. The code works great with s3://<bucket name>, but it seems that it does not recognize the new S3 URI.
Here is how the sink is defined in my code:
final FileSink<ConsumerRecordPOJO<CacheInfo>> sink = FileSink //
.<ConsumerRecordPOJO<CacheInfo>>forRowFormat(new Path(s3Url),
new Encoder<ConsumerRecordPOJO<CacheInfo>>() {
#Override
public void encode(ConsumerRecordPOJO<CacheInfo> record, OutputStream stream)
throws IOException {
GzipParameters params = new GzipParameters();
params.setCompressionLevel(Deflater.BEST_COMPRESSION);
GzipCompressorOutputStream out = new GzipCompressorOutputStream(stream, params);
OBJECT_MAPPER.writeValue(out, record);
out.finish();
}
}) //
// (some extra configuration omitted here)
.build();
After passing s3://arn:aws:s3:ap-southeast-1:<account number>:accesspoint/<bucket name> to the s3Url param, the job execution failed with

It turns out I could use the S3 access point alias which works perfectly for Flink

GraalVM native image with micronaut and aws sdk-v2

I have an issue when building a GraalVM native image using micronaut and aws sdk-v2. Before detailing the error I want to note that before using the sdk-v2 the native image was built correctly.
Once I updated to aws sdk-v2 (via micronaut dependency as):
...
implementation "io.micronaut.aws:micronaut-aws-sdk-v2:2.0.2"
...
I get an error when the trying to built the image

My assumption was that micronaut must be doing some reflection internally and that is making the build process to fail.
I have added the following json file to set a reflection configuartion
[
{
"name" : "io.micronaut.core.graal.AutomaticFeatureUtils",
"allDeclaredConstructors" : true,
"allPublicConstructors" : true,
"allDeclaredMethods" : true,
"allPublicMethods" : true
},
{
"name":"io.micronaut.core.graal.AutomaticFeatureUtils",
"methods":[{"name":"initializeAtBuildTime","parameterTypes":["org.graalvm.nativeimage.hosted.Feature$BeforeAnalysisAccess","java.lang.String[]"] }]
}
]
However the error persists. Not sure if it is due to the fact that AutomaticFeatureUtils.initializeAtBuildTime is expecting a varargs of strings and however in the stacktrace I can see just one String being passed, or the error is not related to reflection at all.
No matter what I try, that method is not found when building the image.
Any idea on what I may be missing here?
Thanks!!

This error is not related to reflection.
Feature and AutomaticFeature are GraalVM native image concepts that allow programmatic configuration for the native iamge, more details can be found for example in the javadoc: https://github.com/oracle/graal/blob/master/sdk/src/org.graalvm.nativeimage/src/org/graalvm/nativeimage/hosted/Feature.java#L59
The error you show happens during the image generation, this is a normal java process, which doesn't need to have reflection configured etc. Those are the configuration for the runtime behavior.
What the error says is that AwsSdkAutomaticFeature (source tries to call void io.micronaut.core.graal.AutomaticFeatureUtils.initializeAtBuildTime(org.graalvm.nativeimage.hosted.Feature$BeforeAnalysisAccess, java.lang.String) but there's no such method. Most probable cause is the version mismatch between the dependency and the core micronaut library that contain graal support.

Cause
This exception can mean that the connection to the client browser was
aborted before the response is fully transferred. It is a harmless
warning as it can be due to transient network problems or the user
aborts/refreshes the page before it loaded.
A list of other causes are:
The user closed the browser before the page loaded.
Their Internet connection failed during loading.
They went to another page before the page loaded.
The browser timed the connection out before the page loaded (would
have to be a large page).
Resolution
This can be ignored, unless there are other issues that are currently
occurring. For example, if the your application server is throwing a
lot of these, it might be a sign of a performance problem.

ServletUnit RequestDispatcher forward() / include() methods AbstractMethodError

I'm doing a java web app with a servlet and I wanted to write some tests to check its functionality (ex. authorization form). I hadn't been using any framework, just bare java in eclipse with tomcat 7.0
I've run into an error while trying to test authorization input. The app would check the login-password pair and then redirect using RequestDispatcher.forward() or RequestDispatcher.include() methods. But when executing them it throws an error with the following stack trace:

The first block represents an invocation error caught by central controller (Dispatcher) servlet while invoking method in which an AbstractMethodError had been thrown. The second and third ones are about that error.
The code of the test method is as follows:
#Test
publi­c void testAuthIncorr­ectInput_Long() throw­s Exception {
W­ebRequest request = n­ew PostMethodWebReque­st("http://localhost:­8080/CenralReportDL/D­ispatcher?query=auth"­);
S­tring longString = ne­w String();
f­or (int i = 0; i < 52­; i++) {
­ longString­ += "aA_ba";
}
reque­st.setParameter("user­name", longString);
reque­st.setParameter("pass­word", longString);
W­ebResponse response =­ client.getResponse(r­equest);
a­ssertNotNull("No resp­onse received", respo­nse);
}
How can I get rid of this error? Is there a workaround? Should I maybe use some other means of servlet testing?
Also please do not suggest framework-specific testing utils such as strutstest, I want an actual solution for bare java web application.
UPDATE: In response to #JekinKalariya - I had a JasperException before. It complained about files not being in /WEB-INF folder, but due to my project structure they all were in /WebContent/WEB-INF. I was so frustrated because of that I just copied entire folder. Silly thing to do. I deleted it and now I'm back to that JasperException.
UPDATE: Now, I've done some research and found some answers on this issue. Didn't work for me though. I also found a suggestion to change a target runtime to J2EE Preview, which raised a different kind of exception:
com.meterware.httpuni­t.HttpNotFoundExcepti­on: Error on HTTP req­uest: 404 java.lang.C­lassNotFoundException­: org.apache.jasper.s­ervlet.JspServlet [http://localhost/WEB-­INF/jsp/auth.jsp]
