New enforcement of Java program

Hey,.

So I would be able to run another java program.

File directory = new File(".");
            try {
                List<String> l = new ArrayList<String>();
                l.add("Java "+directory.getCanonicalPath+"AnotherProject/bin/main.class");
                ProcessBuilder pb = new ProcessBuilder(l);
                pb.start();
            } catch (IOException ex) {
                ex.printStackTrace();
            }

What I am doing wrong? I get the error message: "No such file or directory."

It is entirely up to you! This will be your point of entry. If you are able to think you application as a server of two parts, a customer and you have no problem to build the parties separated in applications of 'work', then their respective main methods would be good enough as beginning-methods. It's just a name.

Really, the principle is simple, let's assume that you have a HelloWorld class (think server) and one as a search for class GoodbyeMoon (think client):

public class GoodbyeMoon {
     public static void main(String[] args) {
          System.out.println("Good bye, Moon!");
     }
}

Then you're application can do this:

public class LoginMain {
     public static void main(String[] args) {
                // ... GUI to select MOON or WORLD
                if (userSelection == MOON ) {
                      GoodbyeMoon.main(null);
                } else {
                      HelloWorld.main(null);
                }
     }
}

I had the same problem on Saturday, Oct. 12, and Sunday, Oct. 13. However, I was able to download and install update 40 this morning (Monday, 14 October) successfully. It must have been a problem with the Java download site as there is problem in Firefox and IE, and it seems to be fixed now.

When firefox loads I get an error message "cannot find / / / jpsnotify.exe." now load Firefox, but every time I go into something else, it seems. This started to happen when I downloaded a new version of java.

I downloaded a new version of Java and then I started to have a "windows can't find c:\java\jre6\lib\deploy\jqs\ff\...------..» \.. \bin\jqsnotify.exe. now, this only happens when loading firefox. It happens through the use of firefox during the loading of other programs. any suggestions?

This has happened

Each time Firefox opened

Try to reinstall Java. See using the Java plugin to display interactive Web sites content

A quick search for jqsnotify.exe on Google indicates that it is related to the Java QuickStart option.

Java program freezes computer

Hey guys, I'm having a problem with a java program that cause my computer to freeze when I open the program. The computer is running Windows XP. The program I use is the specific work for my work. Really no one else using this program except my business, it is manufactured by our company. Yes, I should ask them what the problem is, but they eventually give a new computer, which is a huge pile of * and end by removing important information and programs on my computer that they will not re - install (programs are locked on their license key that they don't tell anyone) is there a way you guys can help me solve what's happening? It's really important for me to get this program to work correctly since it is my work that revolves around it. The program opens, but it's like a 50-50 chance. I really appreciate it!

Find the path of the competing java program
Hi all

I work with iRecruitment responsibility of the recruiter.
Here I can create new job opportunities.
After the creation of vacancies, they should be approved by a Manager

When I create vacancy and submit this vacancy for approval
It is stored in table hr_api_transactions.

and when the Manager has approved this particular post then this vacancy
stored in another table per_all_vacancies.
But the problem is this position that stored in the hr_api_transactions table
It removes from this table.
I want to know who transfer the information of this hr_api_transactions to per_all_vacancies table manager vacancy.

In my view, there are some concurrent java programs that transfers information of vacancy from one table to another table.

If there is no concurrent java programs, so that that work?
Double wire.

ROWID in java program update
Hi people,

I update a row by using the ROWID in java program, it is not to update the documents based on the rowid... I copy the code example

try {}

for (i = 0; i < size; i ++) {}
stmt.clearParameters ();

oracle.sql.ROWID (oracle.sql.ROWID) = list.get (i) ROWID.

stmt.setString (1, table);
stmt.setString(2,idArray[i]);
stmt.setString(3,message[i]);
stmt.setROWID(4,rowIds);
stmt.executeUpdate ();
stmt.addBatch ();

}

Java method to date SQL

private String getUpdateSqlString() {}
StringBuffer sql = new StringBuffer (20);
SQL. Append ("update xx_custom_table set status_flag =?,");
SQL. Append ("id =?, status_message =?") where rowid =? ");
SQL. Append ("status_flag = 'U'");

Return sql.toString ();
}

Can someone explain this?

Thank you

I checked the list, valid rowid is filled in in the list.

Can you explain how determine you who and what, exactly, do you mean by "valid rowid '?

You declare that all LIST items is
-A ROWID into a format valid
-This corresponds to a line in XX_PRODUCT_TABLE
-Where STATUS_FLAG = 'U' already?

The only way to get this information is to query the XX_PRODUCT_TABLE table, probably if you do this before this code snippet runs. Any chance that the line is modified or deleted by another session between the moment where you query the database to get the ID and when you run the update?

And, more generally, why are you using the ID here? It seems strange that you could identify lines of update, store the set of rows to be updated in a collection of Java and then course this collection to make the actual updates. A simple UPDATE based on a game, or at least a stored procedure, would seem much more effective...

After the "new version" download Java 6 times, my plugin check page indicates that he has disabled my 'version outdated' and asks me to upgrade. What do I do?

Background:
I had this problem for several months now. This problem started when an update came to Java on the Firefox Plugin check. Quickly, I installed the new update of Java. But the Firefox update register that I downloaded, even though I refreshed the page. So, I got rid of the old Java and downloaded again the new Java. When the page has continued to post the same message he had before, I downloaded a few times more. Finally, Firefox stopped to say that I was at day. Then a few weeks later perhaps I check Firefox Plugin, and on the page it says that I'm overwhelmed in Java. So I downloaded Java again. But Java was still in the list, with the red and said that he had to be updated. I restarted the computer. Then I restarted Firefox Mozilla with no Add-ons. When Java appeared still to be updated, I gave up and did not something more on this topic.
Problem:
Today, I decided to check my plugins. Java was not updating the list, and at the top a banner said, "Missing JAVA? For your security, Firefox has disabled your outdated version of Java. Please install the latest version. "I clicked on"upgrade to the latest version"and was brought to the Java page. I clicked on the download button. My cache indicates that it was this same Java plug-in (see background) download (6). I chose the re - download anyway. But Firefox always insists on the fact that I him have not downloaded.
Question:
Should I go to the control panel of Java and change something? I have to fix a few settings on Firefox? Should I disable Java entirely, delete all the files related to Java on my computer and start over with Java? What should I do?

Try to use http://ninite.com/java/ninite.exe to install Java. Please note that even if download you it you have to double click it to run and install.

Start your computer Safe Mode and check if you can successfully start.

Safe mode starts Windows with a limited set of files and drivers. Startup programs do not work in safe mode, and only the basic drivers needed to start Windows are installed.
