I am getting exception when I try to use SendGrid sg = new SendGrid(sendGridAPIKEY);
It gives exception because send grid uses HttpClientBuilder.create().build(); internally.
I resolved this issue by adding following lines
DefaultHttpClient defaultHttpClient = new DefaultHttpClient();
Client sendGridClient = new Client(defaultHttpClient, false);
SendGrid sg = new SendGrid(sendGridAPIKEY, sendGridClient);
where DefaultHttpClient is deprecated.
But I want to know why HttpClientBuilder.create().build() line gives error.
I am using JDK 1.8 and following POM dependency

I am getting this java.lang.NoClassDefFoundError: Could not initialize class com.azure.sto rage.blob.implementation.util.ModelHelper when trying to initilalize Azure Blob like this
StorageSharedKeyCredential credential = new StorageSharedKeyCredential(ACCOUNT_NAME, ACCOUNT_KEY);
BlobServiceClient storageClient = new BlobServiceClientBuilder().endpoint(endpoint).credential(credential).buildClient();
How to solve this?

Here, was able to use blobserviceclient to create a container in storage using the following code.
DefaultAzureCredential k = new DefaultAzureCredentialBuilder().build();
BlobServiceClient blobServiceClient = new BlobServiceClientBuilder()
.endpoint("https://<storageaccount>.blob.core.windows.net/")
.credential(k)
.buildClient();

Now let's come to the NoClassDefFoundError error, well you get this error when the JVM is calling a class and not being able to find it at run time.
Maybe the ModelHelper and the MapperBuilder class/dependency are not at the same location as everyone else. What you can do is uninstall everything and then reinstall everything. Then recompile the project.
Refer this article on NoClassDefFoundError by Rollbar

We have the dwr.jar in the WEB-INF/lib dir (and I opened it and checked, the org/directwebremoting/extend/ConvertUtil is there)

In my Tapestry application, I need to do a GET request to a certain URL at some point. I do it like this (using Apache's HttpClient 4.2.1)
String scheme = getScheme();
String host = getHost();
int port = getPort();
String path = getPath();
String paramKey = getParamKey();
String paramValue = getParamValue();
URIBuilder builder = new URIBuilder();
builder
.setScheme(scheme)
.setHost(host)
.setPort(port)
.setPath(path)
.setParameter(paramKey, paramValue);
URI uri = builder.build();
HttpGet getRequest = new HttpGet(uri);
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpResponse response = httpClient.execute(getRequest);
When I deploy my WAR on Glassfish (3.1.2.2) and the code in question is executed, the following exception is thrown:

<dependency>

<version>1.1.1</version>
</dependency>
And I checked and made sure the Class that is "not being found" is actually in WEB-INF/lib/log4j-1.2.14.
Is there any way to solve this issue?
You have a classloader problem. Maybe another web application, that uses different log4j version, is loaded first. The classloader uses the first version of the class it finds.
Try this:
Remove all other applications from app server
Check that you don't have another log4j in classpath of the server.
Try to install and start your application.
I can't run up my RESTful service with embedded Jetty 7 and Jersey. When I call my simple hello test I get:
javax.ws.rs.WebApplicationException: com.sun.jersey.api.MessageException: A message
body writer for Java class java.lang.String, and Java type class java.lang.String,
and MIME media type text/plain was not found
I saw errors similar posted here on SO, but it was for custom classes, and mine is for just String. Any hints? My init server code:
ServletContextHandler context = new ServletContextHandler(ServletContextHandler.SESSIONS);
context.setContextPath("/");
server.setHandler(context);
ServletContainer container = new ServletContainer();
ServletHolder h = new ServletHolder(container);
h.setInitParameter("com.sun.jersey.config.property.packages", "api");
context.addServlet(h, "/res/*");
And dependances:
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.11.1</version>
</dependency>
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-server</artifactId>
<version>7.1.6.v20100715</version>

Do you have any hints?
Exchange jersey-server to :
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-bundle</artifactId>
<version>1.11.1</version>
</dependency>
