OAF : Programatically Add Region to OA Page

Sometimes in OAF, you want to add a region to OA Page.

For example i had a requirement to add employee summary region to another page.
Employee Summary Page exists at MDS at this path "/oracle/apps/per/selfservice/common/webui/AsgSummaryRN".

Application module that is used with this region is "oracle.apps.per.selfservice.common.server.SummaryAM"

I wrote the following code to add this page to another page at controller of OA page

ipublic void processRequest(OAPageContext pageContext, OAWebBean webBean) {
 super.processRequest(pageContext, webBean);
 
 OATableLayoutBean empSummaryBeean = 
  (OATableLayoutBean)this.createWebBean(pageContext, 
             "/oracle/apps/per/selfservice/common/webui/AsgSummaryRN", 
             "AsgSummaryRN", true);
 empSummaryBeean.setApplicationModuleDefinitionName("oracle.apps.per.selfservice.common.server.SummaryAM");
 empSummaryBeean.setStandalone(true);
 webBean.addIndexedChild(0, empSummaryBeean);
}

OAF : Disable Global Buttons in Page

I write snippet code to disable global buttons in OAF page.
You can add the following code to Controller class of the page that you want to disable global buttons inside it.

    public void processRequest(OAPageContext pageContext, OAWebBean webBean) {
        super.processRequest(pageContext, webBean);

        OAPageLayoutBean pageLayoutBean = 
            (OAPageLayoutBean)pageContext.getPageLayoutBean();
        pageLayoutBean.prepareForRendering(pageContext);

        OAGlobalButtonBarBean globalButtonsBean = 
            (OAGlobalButtonBarBean)pageLayoutBean.getGlobalButtons();
        globalButtonsBean.setRendered(false);
    }

Thanks

Route HTTP to HTTPS in HttpClient

I published before an article about JAVA : Get html Page Source through Website URL that HttpClient was used to send Get method and get Response.

Sometime developer want to route Http to Https when invoking Urls.
So You can use WebClientWrapper.wrapClient to do this issue.

import java.security.cert.CertificateException;
import java.security.cert.X509Certificate;

import javax.net.ssl.SSLContext;
import javax.net.ssl.TrustManager;
import javax.net.ssl.X509TrustManager;

import org.apache.http.client.HttpClient;
import org.apache.http.conn.ClientConnectionManager;
import org.apache.http.conn.scheme.Scheme;
import org.apache.http.conn.scheme.SchemeRegistry;
import org.apache.http.conn.ssl.SSLSocketFactory;
import org.apache.http.impl.client.DefaultHttpClient;

public class WebClientWrapper {
    public static HttpClient wrapClient(HttpClient base) {
        try {
            SSLContext ctx = SSLContext.getInstance("TLS");
            X509TrustManager tm = new X509TrustManager() {

                public void checkClientTrusted(X509Certificate[] xcs,
                                               String string) throws CertificateException {
                }

                public void checkServerTrusted(X509Certificate[] xcs,
                                               String string) throws CertificateException {
                }

                public X509Certificate[] getAcceptedIssuers() {
                    return null;
                }
            };
            ctx.init(null, new TrustManager[] { tm }, null);
            SSLSocketFactory ssf = new SSLSocketFactory(ctx);
            ssf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
            ClientConnectionManager ccm = base.getConnectionManager();
            SchemeRegistry sr = ccm.getSchemeRegistry();
            sr.register(new Scheme("https", ssf, 443));
            return new DefaultHttpClient(ccm, base.getParams());
        } catch (Exception ex) {
            ex.printStackTrace();
            return null;
        }
    }
}

JAVA : Get html Page Source through Website URL


To get source code of website page you can use HttpClient ,I will  send GET method and then get response.
The response has content of website URL.

I used Apache HttpClient package to implement this task.

In this Class I used  getStringFromInputStream method that was I was posted before in Convert InputStream to String.

here you can find Class do this task
Note I use static method WebClientDevWrapper.wrapClient, you can find its code in the article Route HTTP to HTTPS in HttpClient

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

import org.apache.http.HttpEntity;
import org.apache.http.HttpResponse;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.client.HttpClient;
import org.apache.http.impl.client.DefaultHttpClient;

public class WebsiteSource {
    public static String getSource(String url) throws Exception {
        String retValue = "";
        HttpClient httpclient = new DefaultHttpClient();
        WebClientDevWrapper.wrapClient(httpclient);
        try {
            HttpGet httpget = new HttpGet(url);

            // Execute HTTP request
            HttpResponse response = httpclient.execute(httpget);

            //Get status : Response Ok will be HTTP/1.1 200 OK
            System.out.println(response.getStatusLine());

            // Get hold of the response entity
            HttpEntity entity = response.getEntity();
            if (entity != null) {
                InputStream instream = entity.getContent();
                try {
                    retValue =
                            WebsiteSource.getStringFromInputStream(instream);

                } catch (RuntimeException ex) {
                    httpget.abort();
                    throw ex;
                } finally {
                    // Closing the input stream will trigger connection release
                    try {
                        instream.close();
                    } catch (Exception e) {
                    }
                }
            }

        } finally {
            httpclient.getConnectionManager().shutdown();
        }
        return retValue;
    }

    private static String getStringFromInputStream(InputStream is) {

        BufferedReader br = null;
        StringBuilder sb = new StringBuilder();

        String line;
        try {

            br = new BufferedReader(new InputStreamReader(is));
            while ((line = br.readLine()) != null) {
                sb.append(line);
            }

        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (br != null) {
                try {
                    br.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }

        return sb.toString();

    }

    public static void main(String[] args) {

        try {
            String content =
                WebsiteSource.getSource("http://mahmoudoracle.blogspot.com/");
            System.out.println(content);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
