I am new to FreeTTS and this is my first program.The following program simply reads out a string passed.
I am using Linux Mint 32-bit if that matters.But I extracted jsapi.jar on my windows machine a day back.I believe it doesn't matter.
import javax.speech.*;
import java.util.*;
import javax.speech.synthesis.*;
public class Speak
{
String speaktext;
public void dospeak(String speak,String voicename)
{
speaktext=speak;
String voiceName =voicename;
try
{
SynthesizerModeDesc desc = new SynthesizerModeDesc(null,"general", Locale.US,null,null);
Synthesizer synthesizer = Central.createSynthesizer(desc);
synthesizer.allocate();
synthesizer.resume();
desc = (SynthesizerModeDesc) synthesizer.getEngineModeDesc();
Voice[] voices = desc.getVoices();
Voice voice = null;
for (int i = 0; i < voices.length; i++)
{
if (voices[i].getName().equals(voiceName))
{
voice = voices[i];
break;
}
}
synthesizer.getSynthesizerProperties().setVoice(voice);
System.out.print("Speaking : "+speaktext);
synthesizer.speakPlainText(speaktext, null);
synthesizer.waitEngineState(Synthesizer.QUEUE_EMPTY);
synthesizer.deallocate();
}
catch (Exception e)
{
String message = " missing speech.properties in " + System.getProperty("user.home") + "\n";
System.out.println(""+e);
System.out.println(message);
}
}
public static void main(String[] args)
{
Speak obj=new Speak();
obj.dospeak("Finally It speaks and speaks and speaks","kevin16");
}
}
I am getting this as a gift.

What can I do not to accept this gift.
PS
I have added all the 4 archives viz en_us.jar,freetts-jsapi10.jar, jsapi.jar,mbrola.jar
1) Find in which jar this class is usually defined:
com.sun.speech.freetts.ValidationException
2) See if you have the jar
3) See if you have the right version of this jar
(open it, see if the class file is there)
4) See if the jar is in the classpath at runtime

I am using ASM 5.2 for an example project and I want to compile the project which has as dependacy the ASM library.
The java file i am trying to compile is the following:
import java.io.FileInputStream;
import org.objectweb.asm.ClassReader;
import org.objectweb.asm.ClassVisitor;
import org.objectweb.asm.MethodVisitor;
import static org.objectweb.asm.Opcodes.ASM5;
public class Parser2 {
public static void main(final String args[]) throws Exception {
FileInputStream inputFile = new FileInputStream("/src/Test.class");
ClassReader reader = new ClassReader(inputFile);
GraphClass gc = new GraphClass();
reader.accept(gc, 0);
}
}
class GraphClass extends ClassVisitor {
public GraphClass() {
super(ASM5);
}
public MethodVisitor visitMethod(int access, String name, String desc, String signature, String[] exceptions) {
GraphMethod newVisitor = new GraphMethod(name);
return newVisitor;
//return super.visitMethod(access, name, desc, signature,exceptions);
}
}
class GraphMethod extends MethodVisitor{
public String MthName;
public GraphMethod(String name) {
super(ASM5);
MthName = name;
}
public void visitMethodInsn(int opcode, java.lang.String owner, java.lang.String name, java.lang.String descriptor, boolean isInterface) {
System.out.println(owner + "." + MthName + " ===> " + owner + "." + name);
}
}
I compile it with
javac -classpath asm-all-5.2.jar Parser2.java
which creates the class files GraphClass.class, GraphMethod.class and Parser2.class.
Then upon executing the Parser2 the following error comes up.
$ java Parser2

I am trying to implement a simple code to read the data from the ultrasonic and send it to a server by using Californium. The problem is that when I use debug, it doesn't have any error.

The error states that
Caused by: java.lang.ClassNotFoundException: org.eclipse.californium.elements.util.NamedThreadFactory
This means you are writing code that uses a dependency from Californium. That dependency is within your dev. environment but it is not within the runtime environment of your Raspberry Pi.
Have a look at this other post which may help you. Also this SO site may be better.

NullOutputStream removed from Guava 15.
Use ByteStreams.nullOutputStream() instead. This class is scheduled to be removed in Guava release 15.0.
You have to look your guava version.

I would like to save data from each partition to MySQL Database. For doing that I created Class which implements VoidFunction<> :
public class DatabaseSaveFunction implements VoidFunction<Iterator<String>> {
/**
*
*/
private static final long serialVersionUID = -7039277486852158360L;
public void call(Iterator<String> it) {
Connection connect = null;
PreparedStatement preparedStatement = null;
try {
Class.forName("com.mysql.jdbc.Driver");
connect = DriverManager.getConnection("jdbc:mysql://"
+ "xxx.us-west-2.rds.amazonaws.com" + "/"
+ "xxx", "xxx", "xxx");
preparedStatement = connect
.prepareStatement("insert into testdatabase.test values (default, ?)");
while (it.hasNext()) {
String outputElement = it.next();
preparedStatement.setString(1, "" + outputElement.length());
preparedStatement.executeUpdate();
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
} catch (SQLException e) {
e.printStackTrace();
} finally {
try {
connect.close();
preparedStatement.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
And in my main method class I'm calling:
output.foreachPartition(new DatabaseSaveFunction());
I'm getting following error:

Can anybody tell me what I'm doing wrong ? I would be very grateful for that.
Export the external class to jar and add that like sc.addJar("/path/x.jar") where sc is JavaSparkContext in your main. Then you wont get this error. The error is because you spark program is not able to find the class. Moreover in spark 1.3 and greater you can simple use a map options of jdbc and then use load("jdbc", options) to create a data frame and load data from any RDBMS. its really handy. I am not sure if this method works for connecting any RDBMS into spark. Please tell me if you have any other question.
I am trying to use Java DB for app only storage.
Environment Variables:
CLASSPATH:
%JAVA_HOME%\jre\lib;%DERBY_HOME%\lib\derby.jar
DERBY_HOME:
C:\Program Files\Java\jdk1.7.0_25\db
Path:
%DERBY_HOME%\bin
No changes in eclipse configurations was done and i cannot include it to build path(it somehow will be considered as third party library, which is not allowed)
When i type "sysinfo" in cmd it tells me Db is instaled and list packages and other info.
Code:
public class Main {

pTable.populateTable();
} catch (SQLException e) {

e.printStackTrace();
}

Refering to the documentation there are two things to do in case you get a java.lang.ClassNotFoundException: org.apache.derby.jdbc.EmbeddedDriver if you run the SampleApp.
Configure Embedded Derby
Verify Derby
As you said that you checked sysinfo I would try it with adding derby.jar and derbytools.jar even if the tools are optional.
Or you can compare the SampleApp to your App....
Include derbytools.jar, derbyclient.jar as well.
Try putting System.out.println(System.getProperty("java.class.path"));
before Class.forName(...).newInstance()
The output must contain a valid path to derby.jar.
