Overview

Knowledge Agents provides robust Java integration capabilities, allowing developers to seamlessly embed AI-powered knowledge solutions into Java-based applications and systems. Whether you're building enterprise applications, web services, or backend systems, our Java SDK and REST APIs enable quick integration of Knowledge Bar, Knowledge Bubble, and Knowledge Page components.

Java SDK

Installation

The Knowledge Agents Java SDK is available through Maven Central Repository. Add the following dependency to your pom.xml file:

<dependency>
    <groupId>com.knowledgeagents</groupId>
    <artifactId>knowledge-agents-sdk</artifactId>
    <version>1.0.0</version>
</dependency>

For Gradle projects, add this to your build.gradle:

dependencies {
    implementation 'com.knowledgeagents:knowledge-agents-sdk:1.0.0'
}

Quick Start

Initialize the Knowledge Agents client with your API credentials:

import com.knowledgeagents.sdk.KnowledgeAgentsClient;
import com.knowledgeagents.sdk.config.KnowledgeAgentsConfig;

KnowledgeAgentsConfig config = new KnowledgeAgentsConfig.Builder()
    .apiKey("your-api-key")
    .apiSecret("your-api-secret")
    .build();

KnowledgeAgentsClient client = new KnowledgeAgentsClient(config);

Core Components

Knowledge Bar

The Knowledge Bar is a search-enabled widget that provides instant answers from your business content. Integrate it into your Java application using the SDK:

import com.knowledgeagents.sdk.components.KnowledgeBar;

KnowledgeBar knowledgeBar = client.createKnowledgeBar()
    .withTitle("Search Our Knowledge Base")
    .withPlaceholder("Ask a question...")
    .withTheme("light")
    .build();

String htmlEmbed = knowledgeBar.getEmbedCode();

Knowledge Bubble

The Knowledge Bubble offers contextual help and support through a floating widget. Deploy it with:

import com.knowledgeagents.sdk.components.KnowledgeBubble;

KnowledgeBubble bubble = client.createKnowledgeBubble()
    .withPosition("bottom-right")
    .withInitialMessage("How can we help?")
    .withAutoOpen(true)
    .withDelay(5000) // milliseconds
    .build();

Knowledge Page

The Knowledge Page provides a comprehensive help center experience. Create and customize it:

import com.knowledgeagents.sdk.components.KnowledgePage;

KnowledgePage page = client.createKnowledgePage()
    .withTitle("Help Center")
    .withDescription("Find answers to common questions")
    .withLayout("grid")
    .withCategories(true)
    .build();

REST API Integration

For applications that prefer direct HTTP communication, Knowledge Agents provides comprehensive REST APIs accessible from Java applications.

Authentication

All API requests require authentication using your API key:

import javax.net.ssl.HttpsURLConnection;
import java.net.URL;

URL url = new URL("https://api.knowledgeagents.com/v1/queries");
HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
conn.setRequestProperty("Authorization", "Bearer " + apiKey);
conn.setRequestProperty("Content-Type", "application/json");

Query Endpoint

Submit queries to get instant answers from your knowledge base:

import org.json.JSONObject;
import java.io.OutputStream;

JSONObject requestBody = new JSONObject();
requestBody.put("query", "How do I reset my password?");
requestBody.put("context", "account");

conn.setRequestMethod("POST");
conn.setDoOutput(true);

try (OutputStream os = conn.getOutputStream()) {
    byte[] input = requestBody.toString().getBytes("utf-8");
    os.write(input, 0, input.length);
}

int responseCode = conn.getResponseCode();
// Handle response

Lead Capture

Capture leads directly through your Java application:

JSONObject leadData = new JSONObject();
leadData.put("email", "customer@example.com");
leadData.put("name", "John Doe");
leadData.put("company", "Acme Corp");
leadData.put("source", "knowledge-bar");

URL leadUrl = new URL("https://api.knowledgeagents.com/v1/leads");
HttpsURLConnection leadConn = (HttpsURLConnection) leadUrl.openConnection();
leadConn.setRequestMethod("POST");
leadConn.setRequestProperty("Authorization", "Bearer " + apiKey);
leadConn.setRequestProperty("Content-Type", "application/json");
leadConn.setDoOutput(true);

try (OutputStream os = leadConn.getOutputStream()) {
    byte[] input = leadData.toString().getBytes("utf-8");
    os.write(input, 0, input.length);
}

Advanced Usage

Custom Theming

Customize the appearance of Knowledge Agents components to match your brand:

import com.knowledgeagents.sdk.styling.Theme;

Theme customTheme = new Theme.Builder()
    .primaryColor("#0066cc")
    .backgroundColor("#ffffff")
    .textColor("#333333")
    .borderRadius("8px")
    .fontFamily("Inter, sans-serif")
    .build();

knowledgeBar.applyTheme(customTheme);

Event Handling

Listen to events from Knowledge Agents components:

import com.knowledgeagents.sdk.events.KnowledgeAgentsEventListener;

knowledgeBar.addEventListener(new KnowledgeAgentsEventListener() {
    @Override
    public void onQuerySubmitted(String query) {
        System.out.println("User queried: " + query);
    }
    
    @Override
    public void onAnswerProvided(String answer) {
        System.out.println("Answer provided: " + answer);
    }
    
    @Override
    public void onLeadCaptured(Lead lead) {
        // Handle lead capture
    }
});

Analytics and Tracking

Track user interactions and gather insights:

import com.knowledgeagents.sdk.analytics.AnalyticsClient;

AnalyticsClient analytics = client.getAnalytics();

// Track custom events
analytics.trackEvent("knowledge-search", new java.util.HashMap<String, Object>() {{
    put("query", "pricing");
    put("user_id", "user123");
    put("timestamp", System.currentTimeMillis());
}});

Best Practices

Error Handling

Implement robust error handling in your Java integration:

try {
    KnowledgeBar bar = client.createKnowledgeBar().build();
} catch (KnowledgeAgentsException e) {
    System.err.println("Failed to create Knowledge Bar: " + e.getMessage());
    // Implement fallback logic
} catch (AuthenticationException e) {
    System.err.println("Authentication failed. Check your credentials.");
}

Connection Pooling

For high-volume applications, use connection pooling:

import com.knowledgeagents.sdk.http.ConnectionPoolConfig;

ConnectionPoolConfig poolConfig = new ConnectionPoolConfig.Builder()
    .maxConnections(50)
    .maxConnectionsPerRoute(10)
    .connectionTimeout(5000) // milliseconds
    .socketTimeout(30000)
    .build();

KnowledgeAgentsConfig config = new KnowledgeAgentsConfig.Builder()
    .apiKey("your-api-key")
    .connectionPoolConfig(poolConfig)
    .build();

Caching Responses

Improve performance by caching knowledge base responses:

import com.knowledgeagents.sdk.cache.CacheConfig;

CacheConfig cacheConfig = new CacheConfig.Builder()
    .enabled(true)
    .ttlSeconds(3600)
    .maxSize(1000)
    .build();

KnowledgeAgentsConfig config = new KnowledgeAgentsConfig.Builder()
    .apiKey("your-api-key")
    .cacheConfig(cacheConfig)
    .build();

Integration with Popular Java Frameworks

Spring Boot

Integrate Knowledge Agents into your Spring Boot application:

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Bean;

@Configuration
public class KnowledgeAgentsConfig {
    
    @Bean
    public KnowledgeAgentsClient knowledgeAgentsClient() {
        return new KnowledgeAgentsClient(
            new KnowledgeAgentsConfig.Builder()
                .apiKey("${knowledge.agents.api.key}")
                .apiSecret("${knowledge.agents.api.secret}")
                .build()
        );
    }
}

Dependency Injection

import org.springframework.beans.factory.annotation.Autowired;

@Service
public class SupportService {
    
    @Autowired
    private KnowledgeAgentsClient knowledgeAgentsClient;
    
    public String getAnswer(String query) {
        // Use the client
    }
}
