Which Java is invoked?

Is there a way to tell which Java is invoked (without programming some diagnostic) when an applet is called? Also, I need to be able to switch between the MSJVM and Sun's JVM. How can I do that?
Thanks for any insight.

Open the Java console -- at the top of the console should be displayed the JVM's version information.
There is a Java control panel installed by the Sun JVM, which allows you to enable or disable the Sun JVM within MSIE and Netscape Navigator. To get MSJVM, just disable the Sun JVM.

We have basically the same issue when we try to create the interpreter using the embedded method..
I was able to use the interpreter embedded in a java client as long as the weblogic jars were located in a weblogic install if I tried to use them from a maven repository no luck at all...
All of this worked easily in 9.2 now in 10.3 it seems more error prone and less documented.
I have seen close to a 100 posts on issues related to this so is there a document which outlines specifics....
We / I have used weblogic now for almost 10 years and moving from 8.1 to 9.2 was painful and we expected the move from 9.2 to 10.3 not to be soo bad but its proving to be as painful if not more painful than moving to 9.2. We seem to spend a good bit of our time working around issues in the next new release that were not in the previous one..
Any help would be appreciated I think we will open a support case but even that is more painful...
Any help would be greatly appreciated..
PS: We confirmed that all jars in the startweblogic classpath were in the startup. The server we have the embedded wlst instance is a managed server and we are using the component in a war... Are there any restrictions which we are unaware of.
Error we get is
1 [ERROR] com.tfn.autex.order.weblogic.QueueMaintenanceUtility.addQueue():217 Error Adding Queue wowsers JNDI Name wowsers Exception: Invocation Target exception while getting the WLSTOffLineScript path

How to trap a java exception where java is invoked from a .bat file

Hi,
Jgurus,
i have problem here, i am invoking a batch file from my java class using the command Runtime.getRuntime().exec(batch1.bat) now this file is setting some classpath and invoking batch2.bat with some parameters and this batch2.bat is invoking java command which is throwing a exception now i want trap this execption.
xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
:::::code for batch1.bat:::::
set classpath=d:\com\tech\sun\tcc.jar;d:\com\tech\sun\parameter.jar
set TMMHOME=d:\TMM
cd %TMMHome%\bin

You can read the output stream of that other process.
Process p = Runtime.getRuntime().exec(...);
InputStream theOutput = p.getInputStream();
// or you may want the p.getErrorStream()
// now read and parse theOutputAre you sure that will work from an exe in a batch file? It was my understanding that a batch file runs in a shell (a process.) When an executable runs in the batch file a seperate process is created. Thus I would expect that it would have its own stdin/out/err in that case.
However, in newer versions of windows the following will redirect the output to files (there is NO space between the '2' and the '>')
java.exe MyClass >out.txt 2>err.txt
This will work if the above does not (and if your version of windows supports it.)

How can I run Runtime.exec command in Java To invoke several other javas?

Dear Friends:
I met a problem when I want to use a Java program to run other java processes by Runtime.exec command,
How can I run Runtime.exec command in Java To invoke several other java processes??
see code below,
I want to use HelloHappyCall to call both HappyHoliday.java and HellowWorld.java,
[1]. main program,
package abc;

class HelloHappyCall
     public static void main(String[] args){
          try
               Runtime.getRuntime().exec("java -version");
               Runtime.getRuntime().exec("cmd /c java HelloWorld "); // here start will create a new process..
               System.out.println("Never mind abt the bach file execution...");

} When I run, I got following:
Never mind abt the bach file execution...
I cannot see both Java version and Hellow World print, what is wrong??
I use eclipse3.2
Thanks a lot..

Thanks,
But How can I see both programs printout
"Happy Holiday"
and
"Hello World"
??First of all, you're not even calling the Happy Holiday one. If you want it to do something, you have to invoke it.
And by the way, in your comments, you mention that in one case, a new process is created. Actually, new processes are created each time you call Runtime.exec.
Anyway, if you want the output from the processes, you read it using getInputStream from the Process class. In fact, you really should read that stream anyway (read that URL I sent you to find out why).
If you want to print that output to the screen, then do so as you'd print anything to the screen.
in notepad HelloWorld.java, I can see it is opened,
but in Java, not.I have no idea what you're saying here. It's not relevant whether a source code file is opened in Notepad, when running a program.

Which API is invoked by coherence when a object meets it's expiry interval

Hi,
Need an Information about which API is invoked by Coherence Internally when an cached object meets it's expiry delay time or interval?
Will Coherence invokes CacheFactory. releaseCache(NamedCache map) API or CacheFactory.destroyCache()?
We need this details because we see increase in size(byte) of object and count as 0 in our JMX stats. expiry-delay is 10 sec.

Hi Jonathan,
Thanks a lot for the response. We've observed that cached objects size shrinks and it's sporadic and for expired cache objects we see increase in size of the object. We are using following code to calculate size of cache object in bytes.
import com.vladium.utils.ObjectProfiler;
     * Returns the size of near cache
     * @param cache
     * @return size of near cache
     int getSizeInBytes(){
NamedCache cache = CacheFactory.getCache(cacheName);
          return ObjectProfiler.sizeof(((NearCache) cache)
          .getFrontMap());
     }

Which java keyword cannot be used inside the body of a static method?

Which java keyword cannot be used inside the body of a static method, but may be used without problems in a non-static method?

But javac doesn't complain. So I was not partially wrong -- I was completely wrong.It's still better not to use the "this", though. When you explictly reference a static member via an instance reference (theFoo.bar or this.bar, as opposed to Foo.bar) the JLS requires a check that the reference is non-null. Clearly "this" is always non-null, but javac still puts in half of the check. Take the simple class public class Test {
    static int field;
    public void setField(int i) {this.field=i;}
    public void staticSetField(int i) {field=i;}
} and observe the bytecodes produced: $ javap -c Test
Compiled from "Test.java"
public class Test extends java.lang.Object{
static int field;
public Test();
Code:
   0:   aload_0
   1:   invokespecial   #1; //Method java/lang/Object."<init>":()V
   4:   return
public void setField(int);
Code:
   0:   aload_0
   1:   pop
   2:   iload_1
   3:   putstatic       #2; //Field field:I
   6:   return
public void staticSetField(int);
Code:
   0:   iload_1
   1:   putstatic       #2; //Field field:I
   4:   return
}The JIT will get rid of it, but you may as well avoid the waste in the first place. (And if you really do want to check that the reference is non-null, do the check explicitly so that maintainers know it's intentional).

I recommend Maple or Matlab, or if you don't have any money to spend: you could try Maxima: http://maxima.sourceforge.net/ I heard some good things about it.

(Urgent) Using java to invoke other programs

Guys..
is there any way possible to use java to invoke other programs
eg. java.open(TextPad) or java.execute(NotePad)
something like this
Thx guys

Well... im onli 19 and im an interm in a company. My
boss wanted me to help him look for some ways to do
some process.. So actually this is my 1st time trying
out this java forum. I didn't know that you guys took
such a serious views at screen nick... Forgive me for
my ignorance.I actually don't care that much about it, but you might consider changing it for the reasons I gave. You are only 19 now, and might not be an experienced developer, but you will become one later on (if you continue with Java development), and your account can in that case be an asset for you.

Which JAVA version is most stable in 1.6 series?

Which JAVA version is most stable in 1.6 series?

Ideally that would be the latest and greatest available.
In practice, it depends on a whole lot of unknowns. Different JVMs can perform differently on different OSes and with different configs

Which Java Version to develop Java-XML Programs

Hello,
I was wondering if someone could help me figure out which java bundle to download to be able to compile and run java files using the XML parser classes, and also, do I need any third party api's or somthing to use SAX and DOM.
Sincerely
Fredrik G�rander

do I need any third party api's or somthing to use SAX and DOMSince it doesn't come with Java you are going to need something.
I would suggest finding that first and then getting the jdk/jre that matches the version that it requires.

Which java technology best fits this environment

Hi everybody,
I�m new to Java. I want to build an environment in which there is a group of devices, say a desktop, a laptop and a PDA sharing all resources including their CPU cycles and memories. Do you think it is feasible to implement such an environment iusing Java? Which Java technology (/ies) meet(s) the requirements of such an environment?
Thanks in advance,
Best regards,

I�m new to Java. I want to build an environment in
which there is a group of devices, say a desktop, a
laptop and a PDA sharing all resources including
their CPU cycles and memories. Do you think it is
feasible to implement such an environment iusing
Java? Not really. Getting a PDA and a PC to share their memory sounds pretty low-level to me. I wouldn't know whether this is possible at all. Certanly not sharing CPU cycles. If you want to run the stuff as separate slave processes for a master, Java would be okay, I guess. Note that the PDA would be limited in what it can do, though, compared to the full J2SE.
