Introduction

Here are some Java libraries that can be useful for implementers and developers working with IdentityIQ:

OkHttp

OkHttp - A Java library for HTTP and HTTP/2 requests and responses, making integration a breeze.

• http://square.github.io/okhttp/

Retrofit

Retrofit - A Java library for writing REST web-services. Dovetails with OkHttp really well.

• http://square.github.io/retrofit/

GSON

GSON - Google's JSON serialization and deserialization library for managing JSON objects and parsing.

• https://github.com/google/gson

Apache StringUtils

Apache StringUtils - A useful string parsing utility.

• https://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html

Apache Velocity

Apache Velocity - A parsing / templating engine.

• http://velocity.apache.org

Apache exception/ExceptionUtils

Apache exception/ExceptionUtils - An API for reading the Full Stack Trace (entire Root Cause Stack Trace from call hierarchies) and parsing it to see the exception sub string match (in case of defining retryable errors etc.…)

https://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/exception/Ex...

Example Code is for Apache exception/Exception Utils:

import org.apache.commons.lang.exception.ExceptionUtils;

import org.apache.commons.lang.StringUtils;

/**

     * Prepares the exception error message based on the full stack trace

     *

     * @param Exception object

     * @return exception detailed error message

     */

    public static String getStackAsString(Exception e)

    {

      String[] rootCause = ExceptionUtils.getRootCauseStackTrace(e);

      String stackTraceStr = StringUtils.join(rootCause, " ");

      return stackTraceStr;

    }

• DefaultHttpRequestRetryHandler
  • https://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/Defaul...

• AutoRetryHttpClient - retry the request in case of a non-2xx response
  • https://hc.apache.org/httpcomponents-client-ga/httpclient/apidocs/org/apache/http/impl/client/AutoRe...

I would extend this to include nearly all of the Apache Commons libraries.  StringUtils is just one of many.
