How to run Java class application on mac

Hi to all !
I usually develop java applications on PC which are started by typing java >classname< into DOS-console.
Now one application has to be run on MAC OS 9.2 which shurely hasn�t that console. So how can I start it there ?
Thanx in advance
Alex

They have mrj you need to install it, and to launch an application or an applet, you have no console.

Note that on *nix
environment variable names are case sensitive.
Also, you are again being vague; is it [this it|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/javac.html] or [that it|http://java.sun.com/j2se/1.5.0/docs/tooldocs/solaris/java.html]

Windows classpath vs java.class.path error in QuickTime based applet

Hello
I've spent days reading and searching the internet, and I'm still stumped why some Windows installations are not able to run my QuickTime for Java based applet even though QuickTime is installed (the specific error is: java.lang.NoClassDefFoundError: quicktime/QTException). I have some additional details and a question that might spur someone to an insightful nudge.
On a Windows system that fails:
echo %classpath%
.;C:\Program Files\QuickTime\QTSystem\QTJava.zipWhich is where QTJava.zip is found on the (faulty?) system, but java.class.path is just:
java.class.path = C:\PROGRA~1\Java\jre6\classes
Of the dumped system properties, only java.library.path makes any mention of the QTSystem folder (or any other QT or QuickTime related items).
java.library.path = C:\Program Files\Safari;.;C:\Windows\Sun\Java\bin;C:\Windows\system32;C:\Windows;C:\PROGRA~1\Java\jre6\bin;C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Program Files\QuickTime\QTSystem\
I ran across one thread (elsewhere) where the user was having problems with loading some classes from a complex JAR environment, and a solution was to write a custom class loader. After doing so, the user got the same error "java.lang.NoClassDefFoundError: quicktime/QTException" that was resolved by extending the custom class loader to include .zip files. I'm not sure if the solution is relevant, or if he simply broke something in his custom class loader that would have worked otherwise. I've not written a custom class loader and not sure where to begin, so before I ventured down that path I was hoping someone might shed some light as to if this is a dead end or potential solution. This is a signed applet (QuickTime now requires it, even if you are only playing files of the same server) and it does work on several Windows machines and all tested Macs.
Thank you,
Deron

Something is wrong with the library.
Staring at java code will not help you figure that out.
Maybe it isn't intended to be loaded in java but instead it loads java itself?
If not then write a C/C++ basic app that links that dll in and see if you can at least get it to start.

Problem with servicegen and how to convert java classes to webservices

I am a beginner and am trying to convert all my java code into webservices,I have
a java class Test.java and number of other third party libraries and my own java
files that are reffered in Test.java. I want to expose the public methods in Test.java
as webservices.
the serivegen part of My build.xml is as below
<servicegen
destEar="${APPLICATIONS}/${ear_file}"
warName="${war_file}">
<service
javaClassComponents="com.verizon.Test"
targetNamespace="${namespace}"
serviceName="Test"
serviceURI="/Test"
generateTypes="True"
expandMethods="True">
</service>
<classpath>
<pathelement path="${build}"/>
<pathelement path="${java.class.path}"/>
</classpath>
</servicegen>
When i run ant it complains:
[servicegen] weblogic.xml.schema.binding.BindingException: Invalid class received:
interface org.apache.crimson.tree.ElementFactory loaded from file:/apps/opt/crimson.jar!/org/apache/crimson/tree/ElementFactory.class.
All classes that will be serialized or deserialized must be non-interface, non-abstract
classes that provide a public default constructor
I have no clue,Why is Servicegen introspecting the third party class file also?I
just need the public methods in Test.java exposed and Test.java will just use
the third party library.
also,is there a way to tell servicegen to include all these java files X,Y,Z to
the war file/ear files but expose only the public methods of X in the WSDL.
Please help
thanks
Suresh

Hi Bruce,
Thanks very much for the insight u provided.Yes one of my public methods was returning
a element factory.
But let me ask my question this way:
Is there a way to tell servicegen to take only the specified public methods in
a class to make them as webservices?
by default servicegen is taking all the public methods..,i workaround i found
is to deploy the webservice manually by writing the web-services.xml to include
only the required public methods.
thanks

Hi Suresh,
Does your Test.java have a public method that returns the element
factory of an XML document, like "public ElementFactory
getElementFactory ();" or such?
If so, you may want to check out the supported build-in and non-built-in
data types:
http://edocs.bea.com/wls/docs81/webserv/assemble.html#1060696
Concerning your last question, you can use the excludeEJBs, includeEJBs
(in combination with the ejbJar attribute) to specify which non-built-in
data type components should be generated. Or if you use the
javaClassComponents then simply use a comma separated list of class
names.
Hope this helps,
Bruce

}

Two reasons:
1) Setting the system property java.class.path does not change the value of the CLASSPATH environment variable in the first place.
2) Even if it did, the change would not be visible in the original shell because the environment of the Java subprocess is destroyed. You can't change the environment of the parent process from any subprocess, including shell scripts. (That's why you have to "source" and not run .bashrc or .profile to customize environment settings)

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 call java classed in forms 10g

Hi
I am using forms 10g
There is a java class email_class (to send emails and attachments). this java class (email_class) has further used two moere .jar files (activation.jar & mail.jar).
Now I want to use this java class (email_class) in my form to send email and attachment.
Could you please help me how can I do that?
regards

The jar file must be included in CLASSPATH which is set in the Forms default.env (or your own custom env if you created one). If you have not jar'd the class files, then the path to the class files should be included in CLASSPATH. Here is a simple example. Your CLASSPATH will contain many more entries.
CLASSPATH=D:\oracle10g\iDS1012\j2ee\OC4J_BI_Forms\applications\formsapp\formsweb\WEB-INF\lib\frmsrv.jar;D:\oracle10g\iDS1012\jlib\share.jar;D:\oracle10g\iDS1012\jlib\utj.jar;D:\oracle10g\iDS1012\jlib\zrclient.jar;D:\oracle10g\iDS1012\forms\java\frmall.jar;D:\oracle10g\iDS1012\jlib\importer.jar;D:\oracle10g\iDS1012\forms\javaNotice that jar files are included in the path and the last entry is just a directory. In this case, if there are any class files which are not in a jar, they could be stored individually in the \java directory.
Verify that you have at least the following included in your CLASSPATH:
frmsrv.jar
importer.jar
share.jar
utj.jar
zrclient.jar
Do not remove other entries which may exist as they are needed, but ensure that the list includes the above.

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 convert java class file version without decompiling

Hi,
Oracle R12.1.3 i am having illegal access error while try to access the class file version Java 1.3 uses major version 47,So how to convert the class file version without using decompiling.
Current java version is 1.6.0_07
Is there any tool or API for converting class file version?
Thanks,

They are using Oracle R12.1.3 - which is the E- Business Suite.
