Getting started with 24x7 Java API

I am just getting started with the 24x7 scheduler(JAVA edition).
I am basically trying to integrate the scheduler with our main project. But when I try to implement the example code (Given in the Java API, to open a session) I am getting the following error:

"Exception in thread "main" java.lang.NoClassDefFoundError: com/objectspace/jgl/container

at com.softtreetech.scheduler.j24x7.openSession(j24x7.java:246)

at TrialScheduler.main(TrialScheduler.java:32) "

Please get back ASAP.

PN: I am using the registered version of 24x7 scheduler (java edition) and running the scheduler in master mode on a local machine. Also how can I run it in the non-GUI mode?

Thanks

Check debug.log file for more info. You should find the error reason here.

If you run 24x7 v2.1 build 107 or later you can start it as
master.bat nogui
or
master.sh nogui

This will start the scheduler in non-graphical mode.

Thanks for th Input. But the problem is that it is unable to connect to the 24x7 master, I guess that would be a minimum requirement for the rror to show up in the debug.log file.

Which JDK version are you using?
Did you add JDPB24x7.jar and jgl3.1.0.jar files to the project class path?

jdk version: jdk1.5.0_03

Yes I did and that is precisely why the file compiles fine, it gives an error when executed.

: Which JDK version are you using?

Looks like it cannot find classes in com.sybase.dpb.* which still makes me think that either JDPB24x7.jar or jgl3.1.0.jar are not in the path or cannot be found by JVM. Are you adding these files to the class-path when running the program or only when compiling it?

: jdk version: jdk1.5.0_03

: Yes I did and that is precisely why the file compiles fine, it gives an error

I did add it to the classpath (Environment variables --> classpath) but it gave aerror...now I compiled and executed the java files from command line by redifining the classpath there..it seemed to have taken it. Thanks anyways...though I wonder whats going on?
Is this all I have to do to create a new Job folder?
"//Creating a new Job folder

StringHolder buffer = new StringHolder("");

Integer retCode = obj.createFolder( "Weekly Payroll", "Store payroll related jobs in this folder", buffer);

if (retCode.intValue() != 1)

/* Print error */ System.out.println(obj.getLastError());

else

System.out.println("Weekly Payroll folder id is " + buffer);"

This gives a compilation error:

C:\Program Files\24x7_Scheduler\TrialScheduler.java:33: createFolder(java.lang.String,java.lang.String,com.sybase.dpb.IntegerHolder) in com.softtreetech.scheduler.j24x7 cannot be applied to (java.lang.String,java.lang.String,com.sybase.dpb.StringHolder)

Integer retCode = TJScheduler.createFolder( "Weekly Payroll", "Store payroll related jobs in this folder", buffer);

^
Could you please tell me what is wrong? (I have opened a session with an instance of the scheduler)

Last parameter must be defined is an IntegerHolder not a StringHolder. See the docs.
This parameter accepts folder id if createFolder() succeeds.

PS. You can but you don't have to redifine the global CLASSPATH variable. You can simply add the required JAR and class files to the command line using the standard classpath parameter.

Thankyou for the response but please note that there is an error in your documentation. The example gives it as Stringholder instead of Integer hoder.

Thankyou for all the assistance and so sorry about proloning this but I still have errors:

Hm, never seen such error before. Quick Google search turned up the follwoing results:

http://www.google.com/search?hl=en&lr=&biw=1004&q=java.net.SocketException%3A+Software+caused+connection+abort+socket+write+error

It seems to be a problem on the server side or incopatible JDK/JRE versions used on the client (your rpogram) and server (24x7 scheduler). Do you you se them JDK/JRE or different? Do you connect to local or remote server? Does it cause the scheduler to crash? Can you connect to the scheduler after receiving this error.

See the scenario is like this:
I have a scheduler in master mode executing on my machine and I am writing a program to connect to this scheduler locally and create a Job folder.
I Just bought the latest version of your scheduler, the Java edition.
I am using jdk1.5.0_03 and I don't know what JDK version ur latest 24x7 scheduler, Java edition uses.

The scheduler doesn't crash...I can operate on the sceduler after this error occurs too.

The scheduler uses JDK/JRE specified by your JAVA_HOME environment variable. Please make sure you use the same version for both your program and 24x7 Scheduler. Try restarting the scheduler and see it that helps.

JDK for both are the same!
Well I did do the golden rule of restart a couple of times..doesn't work. Could you suggest any other port number?

Why are you asking about a port number? You should be specifying the same port number that you have in the scheduler settings for the remote control. The default number is 1097 by the way.
