    <p>I know this question has been asked a lot of times, but so far, none of the answers previously given have worked for me, here is my code:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;title&gt;Programa&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;div&gt; Introduzca una palabra a buscar: &lt;input type="text" id="INPUT"&gt; &lt;%@ page import="java.net.URL" %&gt; &lt;%@ page import="com.google.gson.*" %&gt; &lt;%@ page import="java.net.URLEncoder" %&gt; &lt;%@ page import="java.io.InputStreamReader" %&gt; &lt;%@ page import="java.io.InputStream" %&gt; &lt;%@ page import="java.io.Reader" %&gt; &lt;%@ page import="javax.swing.*" %&gt; &lt;%@ page import="java.awt.event.*;" %&gt; &lt;%! int min(int a,int b) { return (a&gt;b)? b:a; } int edit_distance(String a,String b) { int n = a.length(), m = b.length(),costo; int[][] mat = new int[n+1][m+1]; for(int i=0;i&lt;=n;++i) mat[i][0] = i; for(int j=0;j&lt;=m;++j) mat[0][j] = j; for(int i=1;i&lt;=n;++i) { for(int j=1;j&lt;=m;++j) { costo = a.charAt(i-1) == b.charAt(j-1)? 1 : 0; mat[i][j] = min(min(mat[i-1][j] + 1,mat[i-1][j-1] + costo),mat[i][j-1] + 1); } } return mat[n][m]; } String resultados_de_la_busqueda(String search) { //Básicamente lo que hace esta función es devolverte una cadena con los resultados de la búsqueda StringBuffer RES = new StringBuffer("&lt;html&gt;"); String google = "http://ajax.googleapis.com/ajax/services/search/web?v=1.0&amp;q="; //El enlace para buscar en google String charset = "UTF-8"; URL url; Reader reader; try { url = new URL(google + URLEncoder.encode(search, charset)); try { reader = new InputStreamReader(url.openStream(), charset); GoogleResults results = new Gson().fromJson(reader, GoogleResults.class); for(int i=0;i&lt;3;++i) { RES.append(results.getResponseData().getResults().get(i).getTitle()); RES.append("&lt;br/&gt;"); RES.append("&lt;a href=\""); RES.append(results.getResponseData().getResults().get(i).getUrl()); RES.append("\"&gt;" + results.getResponseData().getResults().get(i).getUrl() + "&lt;/a&gt;"); RES.append("&lt;br/&gt;&lt;br/&gt;"); } } catch(Exception e) {} } catch(Exception e) {} return RES.toString(); } %&gt; &lt;% //Se supone que acá debo mostrar el resultado de la búsqueda... out.println(resultados_de_la_busqueda("taringa")); %&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>And here is the error I'm getting:</p> <pre><code>org.apache.jasper.JasperException: No se puede compilar la clase para JSP: Ha tenido lugar un error en la línea: 47 en el archivo jsp: /Programa.jsp GoogleResults cannot be resolved to a type Gson cannot be resolved to a type </code></pre> <p>Any idea on what is causing the problem?</p> <p>Edit 1:</p> <p>This is the GoogleResults class:</p> <pre><code>import java.util.List; public class GoogleResults { private ResponseData responseData; public ResponseData getResponseData() { return responseData; } public void setResponseData(ResponseData responseData) { this.responseData = responseData; } public String toString() { return "ResponseData[" + responseData + "]"; } static class ResponseData { private List&lt;Result&gt; results; public List&lt;Result&gt; getResults() { return results; } public void setResults(List&lt;Result&gt; results) { this.results = results; } public String toString() { return "Results[" + results + "]"; } } static class Result { private String url; private String title; public String getUrl() { return url; } public String getTitle() { return title; } public void setUrl(String url) { this.url = url; } public void setTitle(String title) { this.title = title; } public String toString() { return "Result[url:" + url +",title:" + title + "]"; } } } </code></pre>

    1. COWhat's the package name of your `GoogleResults` and `Gson` classes? From the posted code, I think you haven't imported.

    2. COAlso, it looks like you're in the learning process. I'll recommend you to read [How to avoid Java Code in JSP-Files?](http://stackoverflow.com/q/3177733/1065197), the answer written by BalusC will show you good practices to stop having these kind of problems in your JSPs. Buena suerte en tu proyecto!

    3. COGson is from the gson package: http://code.google.com/p/google-gson/ which I imported (hopefully) here: <%@ page import="com.google.gson.*" %> GoogleResults doesn't have a package. It's not that I don't want to learn, but I don't have time to do it, I already had the project done and the teacher told us to not to use swing, and instead use jsp, and well, that's pretty bad.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
