Hello,

I use Java & Oracle, not .NET & SQL Server. Nevertheless, unless I am missing something about .NET, you need a 'commit' after the update and before you close the connection. Otherwise after...

uth,


You can create a new thread at any time. Then if you so desire, let the 'main' thread die by letting the 'public static main' function return. If the thread you created is a 'daemon'...

Remove "#!/bin/csh" from your script. This instructs the shell to begin a new shell session to execute your script. This is why it does not change your 'current' directory. It is the 'new'...

As I was editing an Ant build.xml file today at work it occurred to me that although it seems easy enough, it might in fact be more difficult for a beginner to get to grips with Ant then the standard...

Iamthwee,

Netbeans uses the Apache Ant build tool to do it's compilation. The Ant build.xml file Netbeans uses should create a jar in a directory called 'dist' under the project folder.

Hi,

No, the -cp flag works just the same under Linux. This problem is not classpath related though.

Hello,

Background

The reason you are receiving the 'UnsupportedClassVersionError' is because the 'bash' shell is finding the default installed 'java' bundled with MDK (Mandrake) 10. You can...

Hi,

There are still several problems in the code, please see comments below:

It is an ugly solution I would not personally use in Oracle, though as you say you cannot use sub-querys, I know of on better method.

Also, in my example you do not need to use the 'distinct'...

Hello,

The reason that your query does not work correctly is because by using <> in this manner you are creating a 'partial' Cartesian Join between the two tables. In doing so the query returns...

If you don't want duplicates, why not use a Set. Like the HashSet. A Set enforces no duplicates.

Is C# not an OO language, can you not just return an Object cantaining the two attributes. By returning a Class (Object) you have much more freedom.

I may be wrong here but do you need to 'escape' the path deliminators, like this:

It is used as a path delimiter. Without it multiple specified paths would be parsed as one location.

Hi Nate,

You say you are running this code from the JProc folder. Why then include '.' in your classpath? as in this case '.' and 'C:\WINDOWS\Desktop\JProc\' will be one and the same thing. I am just...

Hi again,

I see this is also in another thread. I believe Jwenting has it right. I completly missed that you are not flushing the buffer, try:

while ((len = in.read(buffer1)) > 0) {

Hi,

Have you tried increasing the JVM's Heap spaces? Research the '-Xms' & '-Xmx' command line parameters. Example:

Is anybody else having problems getting new Work Units from Stanford? It seems every other day or so it has to try many times to get a new WU for me. It is quite annoying.

Morning Richard,

Now that has me rather confused. You should never have seen the output from:
