  • replaceAll() method using parameter from text file

    - by Herman Plani Ginting
    i have a collection of raw text in a table in database, i need to replace some words in this collection using a set of words. i put all the term to be replace and its substitutes in a text file as below min=admin lelet=lambat lemot=lambat nii=nih ntu=itu and so on. i have successfully initiate a variabel of File and Scanner to read the collection of the term and its substitutes. i loop all the dataset and save the raw text in a string in the same loop i loop all the term collection and save its row to a string name 'pattern', and split the pattern into two string named 'term' and 'replacer' in this loop i initiate a new string which its value is the string from the dataset modified by replaceAll(term,replacer) end loop for term collection then i insert the new string to another table in database end loop for dataset i do it manualy as below replaceAll("min","admin") and its works but its really something to code it manually for almost 2000 terms to be replace it. anyone ever face this kind of really something.. i really need a help now desperate :( package sentimenrepo; import javax.swing.*; import java.sql.*; import java.io.*; //import java.util.HashMap; import java.util.Scanner; //import java.util.Map; /** * * @author herman */ public class synonimReplaceV2 extends SwingWorker { protected Object doInBackground() throws Exception { new skripsisentimen.sentimenttwitter().setVisible(true); Integer row = 0; File synonimV2 = new File("synV2/catatan_kata_sinonim.txt"); String newTweet = ""; DB db = new DB(); Connection conn = db.dbConnect("jdbc:mysql://localhost:3306/tweet", "root", ""); try{ Statement select = conn.createStatement(); select.executeQuery("select * from synonimtweet"); ResultSet RS = select.getResultSet(); Scanner scSynV2 = new Scanner(synonimV2); while(RS.next()){ row++; String no = RS.getString("no"); String tweet = " "+ RS.getString("tweet"); String published = RS.getString("published"); String label = RS.getString("label"); clean2 cleanv2 = new clean2(); newTweet = cleanv2.cleanTweet(tweet); try{ Statement insert = conn.createStatement(); insert.executeUpdate("INSERT INTO synonimtweet_v2(no,tweet,published,label) values('" +no+"','"+newTweet+"','"+published+"','"+label+"')"); String current = skripsisentimen.sentimenttwitter.txtAreaResult.getText(); skripsisentimen.sentimenttwitter.txtAreaResult.setText(current+"\n"+row+"original : "+tweet+"\n"+newTweet+"\n______________________\n"); skripsisentimen.sentimenttwitter.lblStat.setText(row+" tweet read"); skripsisentimen.sentimenttwitter.txtAreaResult.setCaretPosition(skripsisentimen.sentimenttwitter.txtAreaResult.getText().length() - 1); }catch(Exception e){ skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } }catch(Exception e){ skripsisentimen.sentimenttwitter.lblStat.setText(e.getMessage()); } return row; } class clean2{ public clean2(){} public String cleanTweet(String tweet){ File synonimV2 = new File("synV2/catatan_kata_sinonim.txt"); String pattern = ""; String term = ""; String replacer = ""; String newTweet=""; try{ Scanner scSynV2 = new Scanner(synonimV2); while(scSynV2.hasNext()){ pattern = scSynV2.next(); term = pattern.split("=")[0]; replacer = pattern.split("=")[1]; newTweet = tweet.replace(term, replacer); } }catch(Exception e){ e.printStackTrace(); } System.out.println(newTweet+"\n"+tweet); return newTweet; } } }

  • Using AsyncTask, but experiencing unexpected behaviour

    - by capcom
    Please refer to the following code which continuously calls a new AsyncTask. The purpose of the AsyncTask is to make an HTTP request, and update the string result. package room.temperature; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.concurrent.ExecutionException; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import android.app.Activity; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class RoomTemperatureActivity extends Activity { String result = null; StringBuilder sb=null; TextView TemperatureText, DateText; ArrayList<NameValuePair> nameValuePairs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TemperatureText = (TextView) findViewById(R.id.temperature); DateText = (TextView) findViewById(R.id.date); nameValuePairs = new ArrayList<NameValuePair>(); for (int i = 0; i < 10; i++) { RefreshValuesTask task = new RefreshValuesTask(); task.execute(""); } } // The definition of our task class private class RefreshValuesTask extends AsyncTask<String, Integer, String> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected String doInBackground(String... params) { InputStream is = null; try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://mywebsite.com/roomtemp/tempscript.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection" + e.toString()); } try { BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); sb = new StringBuilder(); sb.append(reader.readLine()); is.close(); result=sb.toString(); } catch(Exception e) { Log.e("log_tag", "Error converting result " + e.toString()); } return result; } @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); } @Override protected void onPostExecute(String result) { super.onPostExecute(result); //System.out.println(result); setValues(result); } } public void setValues(String resultValue) { System.out.println(resultValue); String[] values = resultValue.split("&"); TemperatureText.setText(values[0]); DateText.setText(values[1]); } } The problem I am experiencing relates to the AsyncTask in some way or the function setValues(), but I am not sure how. Essentially, I want each call to the AsyncTask to run, eventually in an infinite while loop, and update the TextView fields as I have attempted in setValues. I have tried since yesterday after asking a question which led to this code, for reference. Oh yes, I did try using the AsyncTask get() method, but that didn't work either as I found out that it is actually a synchronous call, and renders the whole point of AsyncTask useless.

  • HTTP 500 ERROR on CAS Server while setting SSLVerifyClent as "required"

    - by Huiyu.Bird
    I have 3 servers, a Apache Server, a JBOSS Server and a CAS Server for SSO. The Apache Server resolve all request with a domain such as www.request.com, and the path of CAS Server is www.request.com/cas, and JBOSS Server is www.request.com/jboss (This app got a CAS client). My problem is if I set SSLVerifyClient require for the NameVirtualHost of www.request.com in my Apache Server, I got a HTTP 500 error during the redirecting to the JBOSS Server(http://www.request.com/jboss), after logined in the CAS login page successfully. But everything goes successfully if there is no SSLVerifyClient require . Error logs of my Apache Server : [Mon Apr 19 17:07:25 2010] [error] Re-negotiation handshake failed: Not accepted by client!?

  • Apache Camel ESB for C# and Java EDA

    - by Dokie
    Hi We are looking at integrating some of our coarse grained business Services using an Event Driven Architecture (EDA) and the server side of these Services (REST) are implemented in both Java and .NET (C#). We originally thought of using RabbitMQ (and AMQP protocol) as a neutral and open means (with good client support in these two languages), but it means having to support another runtime (Erlang) alongside Java and the CLR. We are also looking at Apache qPid as that has a Java broker implementation of the AMQP protocol which might eliminate that concern. Does anyone have any experience of trying to use the richer Apache Camel ESB on top of ActiveMQ to integrate Java and .NET Services in a Pub-Sub EDA manner? Have I missed any other possible suggestions as to a route through this? Thanks

  • Android SQLite database gets corrupted

    There are about 100 people using my Android App right now and every once and while I get a crash report to the server with this stack trace: android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2596) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2621) at android.app.ActivityThread.access$2200(ActivityThread.java:126) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1932) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4595) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) at dalvik.system.NativeStart.main(Native Method) Caused by: android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed at android.database.sqlite.SQLiteQuery.native_fill_window(Native Method) at android.database.sqlite.SQLiteQuery.fillWindow(SQLiteQuery.java:75) at android.database.sqlite.SQLiteCursor.fillWindow(SQLiteCursor.java:295) at android.database.sqlite.SQLiteCursor.getCount(SQLiteCursor.java:276) at android.database.AbstractCursor.moveToPosition(AbstractCursor.java:171) at android.database.AbstractCursor.moveToFirst(AbstractCursor.java:248) The result is the app crashing and all the data in the DB being lost. One thing to note is that every time I read or write to the database I get a new SQLiteDatabase and close it as soon as I'm done. I thought this would simplify things, but perhaps that's causing the problem? Is it possible this is just a SQLite bug?

  • Anyone have BlazeDS working with WebLogic Security (j_security_check) ??

    - by Brian
    I'm working on a Flex implementation (currently using SDK 3.5) on WebLogic 10.3 (11G.) We originally used Glassfish v2.1.1 with zero issues (there was an active directory group lookup bug but it did not hinder our progress.) Since transitioning to WebLogic we have an issue where the flexsession is invalidated after logging in using j_security_check: [BlazeDS]Unexpected error encountered in Message Broker servlet flex.messaging.LocalizedException: The FlexSession is invalid. at flex.messaging.FlexSession.checkValid(FlexSession.java:943) at flex.messaging.FlexSession.getUserPrincipal(FlexSession.java:254) at flex.messaging.HttpFlexSession.getUserPrincipal(HttpFlexSession.java:286) at flex.messaging.MessageBrokerServlet.service(MessageBrokerServlet.java:296) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:292) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3594) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2202) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2108) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1432) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) I've tried almost every option in services-config.xml: [security [login-command class="flex.messaging.security.WeblogicLoginCommand" server="Weblogic"/> [!-- Uncomment the correct app server [login-command class="flex.messaging.security.TomcatLoginCommand" server="JBoss"> [login-command class="flex.messaging.security.JRunLoginCommand" server="JRun"/> [login-command class="flex.messaging.security.TomcatLoginCommand" server="Tomcat"/> [login-command class="flex.messaging.security.WebSphereLoginCommand" server="WebSphere"/> --> [/security> I've even completely removed this section with no luck. The login functions correctly from a non-BlazeDS perspective. It authenticates the user correctly. Without authentication, BlazeDS works fine (no errors for any remote calls.) Together its a big ball of fail (invalid flexsession every time.) Has anyone got this working? Any tips?

Now what I am trying to do is have a layout inside each tab. here is what the code looks like myApp extends TabActivity { TabHost tabHost; onCreate() { setContentView (R.layout.main); tabHost = getTabHost(); TabHost.tabspec spec = tabHost.newTabSpec(..).setIndicator(...). setContent(new Intent().setClass(...)); tabHost.addTab(spec); : } } myTab1Actvity extends Activity { ListView myLV; EditText myET; onCreate() { setcontentView (TAB1_LAYOUT); myLV = findViewById(..); : myLV.setAdapter(aa); myET.setOnKeyListener(....) registerforContextMenu(myLV) } } when I run here is the stack trace ERROR/AndroidRuntime(691): java.lang.NullPointerException ERROR/AndroidRuntime(691): at android.widget.TabHost.dispatchWindowFocusChanged(TabHost.java:295) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.widget.TabHost.dispatchWindowFocusChanged(TabHost.java:295) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewGroup.dispatchWindowFocusChanged(ViewGroup.java:661) ERROR/AndroidRuntime(691): at android.view.ViewRoot.handleMessage(ViewRoot.java:1819) ERROR/AndroidRuntime(691): at android.os.Handler.dispatchMessage(Handler.java:99) ERROR/AndroidRuntime(691): at android.os.Looper.loop(Looper.java:123) ERROR/AndroidRuntime(691): at android.app.ActivityThread.main(ActivityThread.java:4363) ERROR/AndroidRuntime(691): at java.lang.reflect.Method.invokeNative(Native Method) ERROR/AndroidRuntime(691): at java.lang.reflect.Method.invoke(Method.java:521) ERROR/AndroidRuntime(691): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) ERROR/AndroidRuntime(691): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) Does the code's flow look OK? basically each Tab has its own activity and each tab has its own layout. It appears that something is wrong in the TabHost - but I am unable to pinpoint it. Any suggestions/Qs you hav e will be very helpful.

  • How are Scala traits compiled into Java bytecode?

    - by Justin Ardini
    I have played around with Scala for a while now, and I know that traits can act as the Scala equivalent of both interfaces and abstract classes. Recently I've been wondering how exactly traits are compiled into Java bytecode. I found some short explanations that stated traits are compiled exactly like Java interfaces when possible, and interfaces with an additional class otherwise. I still don't understand, however, how Scala achieves class linearization, a feature not available in Java. Could anyone explain or provide a good source explains how traits compile to Java bytecode?

  • HTTP 500 a problem on CAS Server while setting SSLVerifyClent as "required"

    - by Huiyu.Bird
    I have 3 server, a Apache Server, a JBOSS Server and a CAS Server for SSO. The Apache Server resolve all request with a domain such as www.request.com, and the path of CAS Server is www.request.com/cas, and JBOSS Server is www.request.com/jboss (This app got a CAS client). My problem is if I set SSLVerifyClient require for the NameVirtualHost of www.request.com in my Apache Server, I got a HTTP 500 error during the redirecting to the JBOSS Server(http://www.request.com/jboss), after logined in the CAS login page successfully. But everything goes successfully if there is no SSLVerifyClient require . Error logs of my Apache Server : [Mon Apr 19 17:07:25 2010] [error] Re-negotiation handshake failed: Not accepted by client!?

  • Equivalent of Bloch's Effective Java for C#

    - by Elliot Vargas
    I've jumped into the C# bandwagon and was wondering if there's an equivalent of Joshua Bloch's Effective Java for the C# world. I've already being able to apply some Java knowledge to C# given their similarity but I'm interested in knowledge to make the most effective use of C# specific features. For example, Generics are not implemented equally in Java and C#, so it's not clear to me if the Java Generic "techniques" will work in C# as well. I'm mostly interested in C# 3.0. That is (of course) unless you guys think I would benefit for looking into versions 1 and 2 features.

    This is a homework question and I'm having a lot of trouble with it - I've managed to do some of it but still cant finish it - can i Please get some help. Q1. Bezier Curves The following example allows you to interactively control a bezier curve by dragging the control points Cubic.java Replace the call to draw the cubic shape (big.draw(cubic)), by your own function to draw a bezier by the recursive split method.

  • How do I get my code to read the spaces between longs?

    - by WahtsUpWorld
    I apologize for any inconvenience that may occur in answering my question, I'm fairly new to programming and I'm so far only in the last weeks of my community college Java I class. The problem I am facing is in my code of which I cannot seem to get the PrintWriter to address the spaces in between my longs' phone number and social security I.D. The entire code consists of two classes in which one pulls from the other the information needed to parse and present the file writer/print writer. Here is the entire code w/ the second class after it: public class FinalProjectGroup1 { public static void main(String[] args) { } public String name; public long ssid; public double pay; public String address; public long number; public void cleanUpConstructor() {} public FinalProjectGroup1(String name, String address, double pay, long ssid, long number){ this.name = name; this.pay = pay; this.ssid = ssid; this.address = address; this.number = number; cleanUpConstructor(); } public void setName(String name) { this.name = name; } public String getName() { return name; } public void setPay(double pay) { this.pay = pay; } public double getPay() { return pay; } public void setSSID(long ssid) { this.ssid = ssid; } public long getSSID() { return ssid; } public void setAddress(String address) { this.address = address; } public String getAddress() { return address;

  • RPC for java/python with rest support, HTML monitoring and goodies

    - by Ran
    Here's my set of requirements: I'm looking for an RPC framework such as thrift, avro, protobuf (when adding services to it) which supports: Easy and intuitive IDL. No serial numbers, no manual versioning, simple... avro is a good example for this. Works with Java and Python Supports both fast binary prorocol, as well as HTTP based restful style. I'd like to be able to use it for both backend-to-backend communication (java-java or python-java) as well as frontend-to-backend communication (javascript to java). The rest support needs to include &param=value input as get/post requests (configurable per request) and output in three possible formats: json, jsonp, XML. Compact, fast, backward compatible, easy to upgrade etc... Provides some nice monitoring interfaces such as: JMX, web page status reports (e.g. packets in, packets out, error rate etc) Ops friendly... no need to take the whole site down to release new versions Both sync and asyc communication ... other goodies are welcome... Is there something out there? So far I've looked at thrift and avro and they are both nice in some ways, but don't check all my list. Thanks
