Problems with a standalone application

[Daphna]

Hi,
We have tried running LimpidLog on a simple java program:
java -javaagent:C:\LimpidLog\limpidlog200.jar=port=9876 <classX>

and registered the <classX> using the GUI Management tool.
We have encountered 2 problems :
1. Sometimes we could only register interfaces, and not classes.
2. Where can we see the printouts? we've tried both file + console keywords, without any   success.

Thanks

LimpidLog works for some java classes, not others, like stated in the Known Issue section.

Wait for the next release. Estimated time: two weeks.

Please try new release 400b.
If you still get the errors, please send following files to us at http://www.acelet.com/company/contact.php.

1. The source code of the java file.
2. The class file (.class file)
3. All class files (.class files) which are needed by the class.

Thank you.

erm, it is not possible to attach class files via a web form!

I have the same problem:

<SNIP>
daniel@kinkyboots:~/tmp/java$ ls
limpidlog410.jar  src  TestApp.class  TestApp.java
daniel@kinkyboots:~/tmp/java$ cat TestApp.java

class TestApp {

  private static Integer i;

  public static void main(String[] args) {
    i = 0;
    while( true ) {
      burp();
      i++;
    }
  }

  private static void burp() {
    System.out.println(Integer.toString(i));
    pause();
  }

  public static void pause (){
    long t0,t1;
    t0=System.currentTimeMillis();
    do{
      t1=System.currentTimeMillis();
    }
    while (t1-t0<1000);
  }
}

when I try to run the GUI component in another terminal, I just get a window that just says 'connect'. Ihave tried various combinations of port, file, arguments, but I never see any log files. Also I tried creating a limpidlog.applicants file with just one line 'TestClass'.

If I could get this to work it would be VERY useful.

[Wei Jiang]

Your java class is TestApp but you submitted "a limpidlog.applicants file with just one line 'TestClass'" not TestApp.

The log file should be on the working directory (where you gave -javaagent option).
See http://www.acelet.com/limpidlog/LimpidLog.html.

It is not the port, otherwise you would get error from connection.

It seems you use GNU java? Try the Java from Sun. I am not sure if this is the problem.

thank you WeiJang.

Indeed, the JDK version was the issue.

Now I will work further on this to see what I can do with it. But it looks very useful indeed.
