Beginner to Java - running programs

I am a beginner with Java. I just installed the Bouncy Castle provider and would like to test some sample codes to see if everything is correctly installed. I downloaded a zip file that contains all of the example code. My question is: Can I run this code straight from a folder on the desktop or does it have to be placed in a certain place in order for it to compile? I thought I all I need is the provider to start using the library. Is this correct or do I need some extra files?
Thanks in advance.

If it is a .zip then what type of files does it contain, .java or .class? If they are .java files then you will need to compile them before you can run the program.

Java Running Program Slower Than Partner

I have a very peculiar issue with a program I've made for a class. We were allowed to work with a partner on this project, and I was optimizing the code to make it run faster. I got to a certain point where I couldn't think of anything else to do, and it was running at about 2.5 seconds. I added it to Dropbox for my partner to download and check out, and when he ran it, he got a time of 0.5 seconds. Same exact code.
We've tried a few things such as re-uploading from both ends to see if there was some difference. I've re-installed eclipse and tried a different version and re-installed the latest JDK. I downloaded the Eclipse IDE for Java developers. That didn't solve the issue. So then I tried compiling the program with javac from the command prompt and running the program that way. This still gave me a time of around 2.5 seconds. I ran the Windows Experience index to see if my computer could have something wrong with it, but it came up with numbers slightly better than before. So it can't be anything wrong with my actual system. I haven't noticed a decrease in performance. So this narrows everything down to the Java environment itself.
We know the program works. It's already been submitted, graded, and returned and like I said, it runs extremely efficiently on my partner's computer. I just can't think of ANY REASON at all this program is running more slowly on my computer. Have any of you encountered an issue like this? I don't want anything to plague me for future projects.
Thanks for any ideas or assistance!
-Cole

The fact that run times were supposed to be a target of around 0.5 seconds for this project is just what concerns me. Other people have achieved that time. Obviously their code is different, but the point I was trying to get across is that I wouldn't be concerned if it were a decimal difference. What concerns me is that it's seconds. You're correct. I'm using an Alienware computer and my partner has the Mac, but the difference should never be that huge. It only gets worse as we try to run more data.
The timer, like you suspected, is clocked from the system timer Java uses. We get the time when it begins and ends and subtract the difference. This is built into the program's main and is printed into an output file at the end.
I understand the thought that the systems are completely different, and I wouldn't be so worried if it were not for the comparison of data with our computers and other classmates. We have statistics other than time from the program that line up with the numbers we should expect based on the professor's approval of students output. So when those statistics are the same and the ONLY difference is the run time, that's what concerns me. And I know it's not an issue of the timer being started incorrectly because you can easily see the difference in performance when ran.
Obviously this won't mean much, but just note as the numbers increase, so do the time differences. However, the statistics are relatively the same. (The files are generated randomly)
Here's some sample data:
Partner's Output:
bin20.txt, with 20 blocks and 10 buffers...
Cache hits: 1398437

Hopefully this information helps clear up some things. Again, I'm just kind of baffled about this, and I don't think it's simply a problem of having different systems.

Java.lang.OutOfMemoryError when running java concurrent program

Hi,
i had written a java concurrent program to create the content items into Oracle Content Manager (OCM). Process the records from interface table and create the content items into OCM by calling the API IBC_CITEM_ADMIN_GRP.upsert_item().
I run the concurrent program with 2000 records in interface table, it's an one to one process, 563 records are processed and 563 content items are created successfully in OCM. After 563 records continuously throws the Exception
EXCEPTION

DBMS_OUTPUT.put_line('EX - bundle validation others--');
x_return_status := FND_API.G_RET_STS_ERROR;

END IF;
in IBC_CITEM_ADMIN_GRP.validate_attribute_bundle() API.
Again running the concurrent program it process another 563 records. Can any one help me to fix this issue?
i figured out the exception. When debug the error, i got the actual error message like this

for this issue i increased the heap memory size up to 1024MB. Still i have the same issue. Can any one help to fix the issue?

ORA-29532: Java call terminated by uncaught Java

-2048 < 0Aren't the null pointer and arrayindexoutofbounds, the ones which you get when you are trying to read beyond your array? (example: when your loop tries to access the 563rd element in your array, since your array index starts from 0)?
May be if you can try to write out your elements in the array, you might see what it is croaking about.

All of glassfish is running fine apart from this.
keytool could be found in /usr/java/latest/bin/keytool.
Do we need to have this in the path? There is no requirement in the
install guide for this, nor did the RPM installation adjust the system
path accordingly.
Hopefully someone can tell my how things ought to be regarding keytool?
Thanks, Tom

Hi Tom,
the procedure to change the master password of glassfish server hosting APEX listener... sounds more like a GlassFish-related topic to me. I guess you'd get the best answers for such questions in a GlassFish-related forum...
For what it's worth, I'll try my best anyway:
Cannot run program "keytool": java.io.IOException: error=2, No such file or directoryThis seems to be a pretty clear error message: keytool , which is probably used to manage the keys for GlassFish users, wasn't found. This means, you're either running on an OS that is not officially certified for GlassFish, or you GlassFish hasn't been configured properly.
You ran
glassfish@ahost:/opt/glassfish3/glassfish/domains/mydom01/config> which java
/usr/bin/java... which indicates you assume your GlassFish is running without JAVA_HOME being set. If that's true, I'd begin to setup you GlassFish properly starting with that parameter.
Anyway, you also found out that
keytool could be found in /usr/java/latest/bin/keytool.... which is not +/usr/bin+ and hence probably not in the global search path of the user on whose behalf your GlassFish is running. So, you could either create a link-set[*] for +/usr/bin/keytool+ to (finally) point to +/usr/java/latest/bin/keytool+, or you setup JAVA_HOME to be +/usr/java/latest+ .
[*] Note that depending on your OS there might be more than one stage of indirection, e.g. my Ubuntu has +/usr/bin/java+ pointing to +/etc/alternatives/java+ which is pointing to +/usr/lib/jvm/java-6-sun/jre/bin/java+ where +/usr/lib/jvm/java-6-sun/+ is pointing to the directory containing the actual JDK to be used. You'll probably find something like that on your system as well. My Ubuntu box has a link for +/usr/bin/keytool+, so I get that when running "which keytool".
Do we need to have this in the path? There is no requirement in the install guide for this, nor did the RPM installation adjust the system path accordingly.Again, this is not a GlassFish forum.
I hope my hints help you solve your problem. If they don't, please choose the appropriate forum for your next post on that topic. And I guess, giving some more information on your OS and how you manage your JDK (and which version you use) will help people there to help you.
Thanks,
Udo

Vim and Eclim (Java): Run Java program in embedded terminal window

Hello all,
I'm trying to create a decent Vim setup for Java programming. I've installed Eclim, and it works alright. However, one annoyance I have is the way that Eclim runs Java programs. When run (via the :Java command in Vim), a Java program runs in a new shell instance pretty independent from Vim, and then when the program terminates (and Enter is pressed), the output is put into a new buffer at the bottom of the Vim window with the output.
The problem with this is that I must press Enter to go back to Vim after the program terminates, and then the output buffer is automatically selected even though I most likely do not care to copy any of the output.
So, this is what I would like to happen:
- I run my Java program somehow (doesn't have to be with :Java)
- A buffer containing the running program in a shell is put on the screen (if not already there)
- The program terminates, and the focus did not change to the output buffer
At the very least, I want the focus to not change to the output buffer after the program is done running.
Any ways to at least somewhat accomplish what I'm trying to get at?

Yeah? I had AP CS when they first introduced the GridWorld case study. I hope you get more out of the class than I did.
I have never used Java except for that and my first CS class at university. I eventually realized that software (as a job) wasn't for me and took a route closer to EE. I still fight to avoid being called a programmer though
I like the idea of programming for a job, not necessarily "software development", something computer science-y sound good to me.
But anyway, to end on an on-topic note, I embedded gvim inside Eclipse as described here.

Getting Java running

I have downloaded j2sdk1.4.0-beta 3 onto my computer which operates on windows 98. the install wizard installed the program and created a folder j2sdk1.4.0-beta 3. If I click on this it opens to reveal other folders, but when clicking on these they continue through and nothing ends up happening.
I have tried to follow the installation notes on the website and it discussed setting the path through the autoexec.bat. Now, this did not come up as a dos prompt set up, but rather a window under the system reconfigure window (and a bunch of others). the autoexec window started off
@ECHO OFF
SET BLASTER=A220 15 DI
LH C:\WINDOWS COMMAND\DOSKEY
So I am not even sure if this is where I am supposed to be and don't want to reset something that will effect the rest of my system.
I've spent several hours trying to figure this out and can't get java running, if anyone can help It would be greatly appreciated!!!! Thanks in advance!!

You need to set up the autoexec.bat file so msdos knows where to look for the javac.exe (compiler) and java.exe (run time enviroment) and other such fun stuff.
To do this is fairly straight forward - if the JDK root directory is on your c: drive in the folder jdk1.2.2, so the path name for that folder would look like "C:\jdk1.2.2". To tell msdos where the compilers and such are add the following (changing the JDK pathname if JDK is in a different location on the c drive):
SET CLASSPATH=.;C:\
PATH=C:\JDK1.2.2\BIN
Now, when you open the command line/msdos prompt you will need to run the autoexec.bat file, so in the case above, it will look in "C:\JDK1.2.2\BIN" when you run javac, java, jardoc etc.... To run it type "autoexec.bat" whilst in the same directory as the autoexec.bat in msdos - you will need to do this each time you activate the msdos prompt - how to set it up so it does it automatically i don't know.
You don't need to change anything else in the autoexec.bat file, and you can copy the autoexec.bat into the directory in which you are developing the java code. You will need to leave the orginal for other programs to use.
As for opening the JDK folders and your computer not doing anything, i think their maybe a problem with the computer itself............
