How to invoke java class automatically at a fixed time everyday

How to invoke a java class automatically using Quartz scheduler or any other simplified way
I am trying to schedule a job in my web application and need to understand conceptually How to make it work using quartz . The job is scheduled to be executed at 4 pm daily. Am testing the same and It works well when i run it as standalone application manually.
How to configure it that when i start my aplication it should run at its own through quartz.
I am avoiding use of servlet init method and java timer though any alternatives there?
Thanks for your help.

I've not see quartz... are you in Windows, Solaris, Linux, or Mac?
Are you using JAR files or class files?
Windows: javaw myClass (I cannot remember right off if you have to have the .class on the end)
Windows: java -jar myJAR.jar
Solaris java -jar myJAR.jar
Linux java -jar myJAR.jar
Mac?

How to invoke Java class from post.POST.jsp

Hi All,
I am trying to invoke a simple java method from post.POST.jsp
I am getting below exception while doing it.
org.apache.sling.api.scripting.ScriptEvaluationException: org.apache.sling.scripting.jsp.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: 32 in the jsp file: /apps/mywebsite/components/customFormAction/post.POST.jsp
The method test() is undefined for the type DatasourceUtil
29:
30:           ///
31:          com.day.test.datasource.DatasourceUtil dsUtil = new com.day.test.datasource.DatasourceUtilImpl();
32:          dsUtil.test();
33:           //dsUtil.validateLogin(request.getParameter("username"), request.getParameter("password"));
34:
35:           ////
It appears to resolve the class correctly. I could run the code, if I only comment dsUtil.test();. As soon as I uncomment, it gives above error.
In the Utill I have a simple void method which will print a simple text. My package structure is as follows.
any help will be great

1. In the interface [1] not the implementation[2] have u defined the method test?
2. If it is implemented, Change the bundle version in bnd file and make a new build. Then from felix console verify the latest version reflected in the bundles.
If 2 works & you are going to make lot of frequent changes then give the version as snapshot till it get stable.
[1] com.day.test.datasource.DatasourceUtil
[2]   com.day.test.datasource.DatasourceUtilImpl

How to call Java class from Forms 6i?

Hi friends,
I need to call a Java class from my Forms 6i application.
(It runs under WIndows XP. It's a client/server application and I have only the client and the Form builder installed on my PC)
I don't know almost anything about Java's world so your help would be very useful for me.
Could you tell me exactly what i have to do?
I've read in metalink several Notes, but they supposed that the Java architecture is already installed in the computer.... I only have the default installation of Developer 6i... so I would need to know:
- How to install/configure the neccesary to execute Java classes without problem
- How to invoke the .class from Forms 6i.
Thanks a lot
Jose.

And also this one:
Problem Description
Installed Forms 6i Rel 2 on a MS Windows machine. When trying to Import the Java
Classes getting the errors
PDE-UJI0001 Failed to create the JVM
Solution Description
You need to to install JDK 1.2.2 to run the Java Importer. And set the PATH's
and classpath's correctly.
Explanation
1. Download and install the JDK 1.2.2.
Possibly available at: http://java.sun.com/products/archive/
2. Assuming the JDK 1.2.2 is installed in c:\jdk1.2.2 directory and the JRE in
C:\PROGRA~1\JAVASOFT\JRE\1.2 directory; ORACLE_HOME=C:\Dev6iR2.
Set the PATH to
set PATH=c:\jdk1.2.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin;C:\PROGRA~1\JAVASOFT\JRE\1.2\bin\classic;%PATH%
( If you are using ias9i then the JDK 1.2.2 comes with the ias installtion ,
in this case please set the PATH to
D:\ias9i\Apache\jdk\bin;D:\ias9i\Apache\jdk\jre\bin;D:\ias9i\Apache\jdk\jre\bin\classic;%PATH% )
3. Set the CLASSPATH to set CLASSPATH=%CLASSPATH%;C:\Dev6iR2\TOOLS\COMMON60\JAVA\IMPORTER.JAR;.
(If you do not set the CLASSPATH correctly you will get the error
PDE-UJI002 Unable to find the required java importer classes)
4. Now run the Forms Builder by using the command.
C:\Dev6iR2\bin\ifbld60.exe
Now the Java Importer Should Run fine.

How to Transport Java Classes used in Mapping?

Hi XI experts,
Within the development of one message mapping, some external java classes are imported and used in my UDF(user defined function). My question is: how will these external java classes be transported to the QA/PRD system? If I choose to use the file system transport method, do I have to manually find these jar files and transport them separately?
Any comments or suggestions are highly appreciated.
Thanks in advance
Luis

Hi Luis,
Normally Mapping programs and External Jars are used in XI using Imported Archive. So this Imported archive once activated will become part of your SWCV and can be transported automatically with the SWCV.
You dont have to worry about transporting it seperately, it will be avilable once you transport your SWCV using File system transport.
Hope this helps,
Regards,
Ananth

How to invoke custom classes from logon PAR

Hi all,
Can someone tell me how I can invoke a java class that I have written on Click of a Submit button from the Help Page of the Login Screens. I have to customise this screen, changing the existing functionality.
Regards,
Ashwini.

Hi Ashwini,
On the onClick method of the Submit button refer the even handler method you have defined in you DynPage and in that event handler you can instantiate the required java class and call its functions.
ex:
in you JSP define:
<hbj:button
     id="submitButton"
     text="Submit"
     tooltip="Click to search the forum"
     onClick="onSubmit"
/>
in you DynPage define a event handler method called 'onSubmit(Event event)' and write you logic.
Cheers
Kiran

No Class Found Error on invoking java class from PL/SQL

Hi There,
I have followed instructions on how to create a java proc in the DB to invoke it from PL/SQL.
I get a 'java.lang.NoClassDefFoundError' error because it cannot access 'org.apache.axis.description.TypeDesc' in this case. The instuctions say to add the supporting jars which contain the additional classes to the project's Additional Classpath's which I have done.
I deploy the java classes and create the java stored proc using JDev.
Can someone please tell me how to go about resolving this?
I can see 'org.apache.axis.description.TypeDesc' in the DB via JDev's Databse connection in the Java Classes tree?
Thanks,
Anthony
