View Replies View RelatedWhy is my create jar file programatically not working? So doing this does create a jar file. When I run the jar file via command line, it gives me "Could not find or load main class ...". I'm not sure exactly why. I took some code i found here: java - How to use JarOutputStream to create a JAR file? - Stack Overflow and apparently it didn't specify the main class so I specifically added it myself. am i doing something wrong? And btw, the file (that contains all the class files) do not have any directories in them. so it's essentially just one folder with a bunch of class files in there. below is the code.
I had the commons-io-2.4 jar referenced into my build path that can be downloaded here: Commons IO - Download Commons IOreason i guess i added to that, though i'm not sure if it was necessary or not, was because it has a file filter which can tell which files are hidden or not and thing is without it it was adding like DS_STORE(which is hidden and i guess unnecessary) to the jar. not sure if this logic is right but just letting you know.

I'm having problems with using the h:inputFile tag with JSF 2.2 and Glassfish 4.0 on Eclipse. The file uploads work when the enctype is set to "multipart/form-data" in the h:form tag, but AJAX will not work. When I leave out the encType (defaults to "application/x-www-form-urlencoded") AJAX works but the uploads do not work, and in fact Glassfish crashes and generates the message:
The request content-type is not a multipart/form-data
Likewise I'm having the same problems with the PrimeFaces file upload tag p:fileUpload. In a JSF 2.0 it works correctly, but with JSF 2.2 it's giving the same problems and generates the message above.
When I start up Eclipse it tells me that Mojarra 2.2.0 is installed. Is this the source of the problem, and if so, how do I install a later version of Mojarra?

View Replies View RelatedWorking on a program that creates an array from a file, organizes it in various ways, and then prints the results. Right now I'm specifically having trouble with the printAry() method - when I try to run it, I receive a NullPointerException for the active line in printAry() (EDIT: line 102). Not sure which sections are important to this, so I will include the client class and most of the service. I realize that the amount of documentation I included is not necessary, but it is required for the class.

I wrote a piece of code:
for(int i = 0; i < x; i++){
System.out.println("Enter students full name:");
sName[i] = result.fullName(sc.nextLine());
sExam[i] = result.examName("VB");
System.out.println("Enter students exam score:");
int scor = sc.nextInt();
sScore[i] = result.examScore(scor);
sGrade[i] = result.examGrade(scor);
}
When i run it i get:
Enter number of students:
1
Enter students full name:
Enter students exam score:
The problem is, i cant enter "full name", program is just jumping to the next step "exam score".

It runs but nothing. My other questions is how can I make a box that will print the results.
I need to find out if one array list is a sub-sequence of another. The elements in the first list all need to be in the second list and must be in the same order. So s1<n, t, a> is a sub-sequence of s2<q, n, f, r, t, d, a>, but s1<a, a, t> is not a sub-sequence of s2<a, t, a>. I need to use iterators to go through each list, and I should only go through each list once (since it has to be in the same order) so nested loops don't seem like they would work because it would start at the beginning of one list every time it moved to another element in the outer loop's list.I seem to have an issue where the itr1. next()
is ignored when in an if statement.
My current code just stalls and will never stop running. I've also switched things around and put the not equal check after the if it is equal and it throws a NoSuchElementException.
import dataStructures.*;
public class Subsequence3
{
public static void main(String[] args)
{
ArrayList<Character> s1 = new ArrayList<Character>();
s1.add('n');
s1.add('p');
s1.add('a');

I have even tried f:ajax, execute= "@this", immediate = true.
there is no divider in the operation. Iadded a print i to confirm the loop works. I tried with and without the brackets..Can you use the i in the operations of the loop? I figured I could since printing it out give me a list of numbers
public class harmonique {
public static void afficherHarmonique( int wholeNumber ) {
int harmonique = 1;
for( int i = 2; i <= wholeNumber + 1; i = i + 1 ) {
System.out.println ("i =" + i);
harmonique = harmonique + (1/i);
System.out.println ("harmonique =" + harmonique);
}
}
}
Currently the while near the end is not working in netbeans. It is saying illegal start of type. This whole section was working before when it was within the public static void method. I moved it to a separate class to try and clear up a, static variable problem. My question is can i fix it to keep it structured this way. Or do I have to put it back into the main method and try to work out the static variable problem a different way.
