In this guide, we'll show you how to avoid conversion on error using Java and the Java.net library.

When converting documents to PDF, you might want to prevent conversion if certain errors occur to avoid generating invalid PDFs.

```java
import java.net.*;
import java.io.*;

// You can get an API key at https://pdfshift.io
String apiKey = "sk_xxxxxxxxxxxx";

URL url = new URL("https://api.pdfshift.io/v3/convert/pdf");
HttpURLConnection connection = (HttpURLConnection) url.openConnection();
connection.setRequestMethod("POST");
connection.setRequestProperty("X-API-Key", apiKey);
connection.setRequestProperty("Content-Type", "application/json");
connection.setDoOutput(true);

String payload = "{\n" +
    "  \"source\": \"https://www.example.com\",\n" +
    "  \"continue_on_error\": false\n" +
    "}";

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

int responseCode = connection.getResponseCode();

// Handle errors:
if (responseCode >= 400) {
    throw new RuntimeException("Request failed with status code " + responseCode);
}

InputStream inputStream = connection.getInputStream();
FileOutputStream outputStream = new FileOutputStream("result.pdf");
byte[] buffer = new byte[1024];
int bytesRead;
while ((bytesRead = inputStream.read(buffer)) != -1) {
    outputStream.write(buffer, 0, bytesRead);
}
outputStream.close();
inputStream.close();

System.out.println("The PDF document was generated and saved to result.pdf");
```

This allows you to fail fast when conversion issues occur.
