Sorry, I'm not sure if I'm in the right forum or if I'm wording it right. People may call this vague or something. I won't care.
Anyway, I've started to get random errors after trying something. It didn't turn out well. Here's the code + errors of my main mod file.

The errors are:
Multiple markers at this line (38, where GameRegistry.registerItem(itemRuby) and so on):
Syntax error on token ".", > expected.
Syntax error on token "(", < expected.
Syntax error on token ".", { expected.
Syntax error on token ")", delete this token.
Multiple markers at this line (46, where public void init(params) is.)
Syntax error on token "(", ; expected.
Syntax error on token ")", ; expected.
Multiple markers at this line (54, where public void postInit(params) is.)
Syntax error on token "(", ; expected.
Syntax error on token ")", ; expected.
That's all I can say. Thanks in advance.
On line 37, you closed the brace. Close it after all your GameRegistry.register

From the error I can understand that problem is in this part
messageBodyPart.setContent(paragraphs, "application/msword"); where I am adding word document content to MIME message body part.
I have tried several other ways to achieve this but not able to do so. Please suggest a way to achieve this?
I got a resolution to this problem.Actually , I have to put different font face and font sizes in email body which I am trying to read from word document.To achieve this I have changed my approach,so instead of word document I have embedded my content into html tags which is quite simple :) , refer the below line of code which will replace word document part
String htmltext = "+
Different Font Size+
Different Font Size+
";
messageBodyPart.setContent(htmltext, "text/html");
During my research one of my friend suggested me following third party API's , it might be helpful to anyone

Say I have an enum
public enum E {A,B,C}
Is it possible to add another value, say D, by AspectJ?
After googling around, it seems that there used to be a way to hack the private static field $VALUES, then call the constructor(String, int) by reflection, but seems not working with 1.7 anymore.
Here are several links:
http://www.javaspecialists.eu/archive/Issue161.html (provided by #WimDeblauwe )
and this: http://www.jroller.com/VelkaVrana/entry/modify_enum_with_reflection
Actually, I recommend you to refactor the source code, maybe adding a collection of valid region IDs to each enumeration value. This should be straightforward enough for subsequent merging if you use Git and not some old-school SCM tool like SVN.
Maybe it would even make sense to use a dynamic data structure altogether instead of an enum if it is clear that in the future the list of commands is dynamic. But that should go into the upstream code base. I am sure the devs will accept a good patch or pull request if prepared cleanly.
Remember: Trying to avoid refactoring is usually a bad smell, a symptom of an illness, not a solution. I prefer solutions to symptomatic workarounds. Clean code rules and software craftsmanship attitude demand that.
Having said the above, now here is what you can do. It should work under JDK 7/8 and I found it on Jérôme Kehrli's blog (please be sure to add the bugfix mentioned in one of the comments below the article).

Sample application & enum:
package de.scrum_master.app;
/** In honour of "The Secret of Monkey Island"... ;-) */
public enum Command {
OPEN, CLOSE, PUSH, PULL, WALK_TO, PICK_UP, TALK_TO, GIVE, USE, LOOK_AT, TURN_ON, TURN_OFF
}
package de.scrum_master.app;
public class Server {
public void executeCommand(Command command) {
System.out.println("Executing command " + command);
}
}
package de.scrum_master.app;
public class Client {
private Server server;
public Client(Server server) {
this.server = server;
}
public void issueCommand(String command) {
server.executeCommand(
Command.valueOf(
command.toUpperCase().replace(' ', '_')
)
);
}
public static void main(String[] args) {
Client client = new Client(new Server());
client.issueCommand("use");
client.issueCommand("walk to");
client.issueCommand("undress");
client.issueCommand("sleep");
}
}
Console output with original enum:
Executing command USE
Executing command WALK_TO
Exception in thread "main" java.lang.IllegalArgumentException: No enum constant de.scrum_master.app.Command.UNDRESS
at java.lang.Enum.valueOf(Enum.java:236)

at de.scrum_master.app.Client.main(Client.java:22)
Now you can either add an aspect with an advice executed after the enum class was loaded or just call this manually in your application before extended enum values are to be used for the first time. Here I am showing how it can be done in an aspect.
Enum extender aspect:
package de.scrum_master.aspect;
import de.scrum_master.app.Command;
import de.scrum_master.util.DynamicEnumExtender;
public aspect CommandExtender {
after() : staticinitialization(Command) {
System.out.println(thisJoinPoint);
DynamicEnumExtender.addEnum(Command.class, "UNDRESS");
DynamicEnumExtender.addEnum(Command.class, "SLEEP");
DynamicEnumExtender.addEnum(Command.class, "WAKE_UP");
DynamicEnumExtender.addEnum(Command.class, "DRESS");
}
}
Console output with extended enum:
staticinitialization(de.scrum_master.app.Command.<clinit>)
Executing command USE
Executing command WALK_TO
Executing command UNDRESS
Executing command SLEEP
Et voilà! ;-)
im running a jdbc program on Sqlite. though i change the environmental variables or define the classpath of the jar file sqlite-jdbc-3.7.2.jar, i get an error stating ClassNotFoundException: org.sqlite.JDBC... how to rectify it?
my code is`
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Sample
{
public static void main(String[] args)throws ClassNotFoundException

Connection connection = null;
try

Statement statement = connection.createStatement();
statement.setQueryTimeout(30); // set timeout to 30 sec.

my jar file is sqlite-jdbc-3.7.2.jar
my class path is D:\jdk1.6.0_45\sqlite-jdbc-3.7.2.jar
my environmental variable is also the same
what should i do?
help pls
i found the solution to my problem...
the class path should be like
`javac Sample.java
java -classpath "D:\jdk1.6.0_45\sqlite-jdbc-3.7.2.jar";. Sample`
the problem is solved:)
Can someone explain why this is making an infinite loop? The hurcdata2 has about 30 straing values in it. I don't understand what the problem is.
import java.util.Scanner;
import java.io.File;
import java.io.IOException;
public class Hurricanes2
{
public static void main(String[] args) throws IOException
{
int i = 0;
int hurricaneNumber = 0;
String hurricanes = "";
File fileName = new File("hurcdata2.txt");
Scanner inFile = new Scanner(fileName);
while (inFile.hasNext())
{
hurricaneNumber++;
}
}
}
In your while - loop you should call inFile.nextLine() to make it process each line in the file.
while (inFile.hasNext()) {
hurricaneNumber++;
String line = inFile.nextLine();
}
As noted in the comment by #ElectricLlama you need to advance your file pointer, to get the next token, otherwise the hasNext() will always be true. Check this question and this tutorial on File I/O in Java.
I have successfully installed JRI and rJava on Windows 7. I am now trying to get it to work on Ubuntu with 64bit OS. I can make rJava calls from within R but getting JRI to work is more difficult. I am running NetBeans 7.1.2 and I have followed various tricks in setting R_HOME and java.library.path to enable all the classes to be loaded. That is, I am past the error messages such as "jri library not found" and "R_HOME not set".
From my java code,I can see that R_HOME = /usr/lib64/R.
The error message I get now is
Fatal error: you must specify '--save', '--no-save' or '--vanilla'
This happens when Rengine is first called:
Rengine r = new Rengine(args,false,null);
This appears to be an error message from R; it seems to be expecting a command line argument. I haven't seen any posting with this error message. Any ideas? Thanks, Peter
Using R in this setting requires you to run R in non-interactive mode. To solve the issue, you need to choose on of the options given in the error message. I would try --no-save first. This prevents R from saving the workspace at the end of the run. In Java code:
String args[] = {"--no-save"};
Rengine re = new Rengine(args, false, null);
I will post my code for anyone trying to replicate these steps. The code is cobbled together from multiple web sources. Sorry for the re-formatting that occurs: I don't know how to show it as straight text.
