I am new to Custom Java and trying to learn it by using the templates in the Cisco site.Whats the best way to write custom java classes.
Is it better to use callstudio or some IDE like Eclipse. I feel like IDEs are more helpful for writing and fixing syntax errors.
For example if I want to use Eclipse as an IDE, do I need to add any audium files to it before start using import commands in the java code?

Call studio is based off eclipse and has the IDE built in. So you can same the same studio to write java code. You can use the java perspective from the studio. You can write code in separate eclipse too as there are advanced eclipse version with added features and built in plugins. Since you are just starting, I would just suggest using Studio as it has pretty much everything you need to write your java code.

Personally, I feel it's easier to get started by using Studio/Eclipse because, as you say, it'll provide intellisense and suggest corrections. It usually does auto-compile and then to test your java class, you can simply copy the compiled java .class file into your Studio application and put it under appname/deploy/java/application/classes. If the code creates a new element (or say it smart), then close the Studio application from the workspace and re-open it by double-clicking app.callflow and the new element will appear under Elements/Local Elements.
To create the Java project, select New/Project/JavaProject/ Enter a name for your Java project and click 'Next'.
Then in the wizard, click on the Libraries tab and click 'Add External Jars' - you'll need to select 'framework.jar', 'servlet.jar' (was called servlet2.3.jar until cvp 9), and if you're extending existing studio elements you'll need 'elements.jar' - do a Search ahead of time, these files are all in the Studio/eclipse/plugins folder somewhere.
Then copy some of the Cisco examples into your Java project. Eclipse will compile. You can then copy the compiled class files into your Studio application and test them (as described above).

Janine..as you descrbied above, I managed to create a class file using one of the template in the developer forum. Then I copied the class file into appname/deploy/java/application/classe folder and restarted the app as you mentioned. But the file is not appearing in local elements. I am using call studio version 8.5 and JDK is 1.7. Do I need to use JDK 1.6 or is it some other issue?

Do you have anything showing in your Call Studio Error Log? If the element is failing to load, an error or warning should be displayed there.

In my experience, a much better place to look is in the Tomcat logs.

Assuming the class is compiled correctly and there are no errors, I would bundle it into jar and deploy it under the lib dir. JDK is not an issue.

The JDK compliance on 8.5 extends to only 6 only. I would therefore first compile with 1.6 and make sure that there are no errors.

Once you close the app out of the Studio workspace, and then
double-click app.callflow, the element should show up under Local
Elements. If it doesn't then there's usually an array indexing problem
in your java code.
In Studio, look under Window > Show View > Call Studio Error Log. This
will display at the bottom of the Studio window, near the Studio
Problems tab. You should select the error, and right-click, select
Properties. This will pop up a box and give you an error message and
Java stack trace.
Usually the error is in the method named GetSettings or GetElementData
or GetExitStates. Each of these has an array. You must specify the size
of the array. And then you MUST initialize each row of the array.
If you either fail to initialize one of the array rows, or if you
initialize a row of the array but the array dimension is smaller than
that (indexOutOfBounds) then the element will fail to show up in the
Studio pane.
Feel free to post your java file online and I'll fix it for you.

public class TEST1 extends ActionElementBase

This is a 'Standard Action' - it doesn't show up as a new element in
Studio.
To use this code, you drag in the Studio element named 'Action'. You can
then name the element in Studio if you like.
In the right side, configuration pane, enter the Java class name
(without a file extension) - 'TEST1' (omit the quotes).
That's all.

Hi Mark
For the audium element to show up in the studio, you will have to implement the ElementInterface in your class. Apart from CVP programming guide, you will also need the javadoc for CVP API. You can download some sample custom elements and the javadocs from http://developer.cisco.com/web/cvp/home

Janine,
We are trying to create a custom element that will call a REST web service and return the results. We have created the custom element that shows up in builder if we don't have the web service java included but it fails when the web service java is added. To try to troubleshoot, we created a "scriptlet" with just the web service code but it fails with an error that seems to relate to version. The code and jar files we used are below...do you have any suggestions? We have tried to confirm versions are compatible with the jar files we are using but we still receive the error. Is there a better/simpler way to do this web service post? Thank you for your assistance!

Jersey 1.5 requires Java 6 by default, so it won't work in CVP versions prior to 9.0, which introduced Java 6 support. You can try rolling back to Jersey 1.2, which supports Java 5, or try recompiling the Jersey source code in Java 5. You should also confirm that the other libraries support Java 5. Alternatively you can skip Jersey altogether and do your REST lookup with basic HTTP client code.

Thanks Ed! That solved the unsupported version error but now the element won't load. We get the below error in the audium.log after restarting CallStudio:
!MESSAGE An error was encountered while attempting to load the element "MyCustomActionElement". The exception was: java.lang.NoClassDefFoundError: com/sun/jersey/api/client/config/ClientConfig!STACK 0java.lang.NoClassDefFoundError: com/sun/jersey/api/client/config/ClientConfig
In googling, we have found several suggested jar files but none of them have solved the issue.
We can run the java and get results back in the console, but when we implement the code in the custom element, we receive the above error.
Has anyone seen this error or have any suggestions?

That class should be in the Jersey jar files. Open up the jar files and see if it's in there. If not something is wrong with the library you downloaded, or you are missing a required Jersey library. If it's there, make sure it's loaded where CVP can see it (in the project lib folder or the common lib folder) and reopen the script or restart Call Studio as necessary to make sure it's loaded.

You can't run jersey 1.5 in CVP 8x, Jersey requires Java 6 which is only supported as of CVP 9. The simpler method would be to ditch Jersey and just use the standard Java API (http://www.mkyong.com/java/how-to-send-http-request-getpost-in-java/) to make your HTTP requests. You can still use a JSON parser to parse the results; that library should be easier to get working than a full web service library.

I am new to Custom Java and trying to learn it by using the templates in the Cisco site.Whats the best way to write custom java classes.
Is it better to use callstudio or some IDE like Eclipse. I feel like IDEs are more helpful for writing and fixing syntax errors.
For example if I want to use Eclipse as an IDE, do I need to add any audium files to it before start using import commands in the java code?

Call studio is based off eclipse and has the IDE built in. So you can same the same studio to write java code. You can use the java perspective from the studio. You can write code in separate eclipse too as there are advanced eclipse version with added features and built in plugins. Since you are just starting, I would just suggest using Studio as it has pretty much everything you need to write your java code.

Personally, I feel it's easier to get started by using Studio/Eclipse because, as you say, it'll provide intellisense and suggest corrections. It usually does auto-compile and then to test your java class, you can simply copy the compiled java .class file into your Studio application and put it under appname/deploy/java/application/classes. If the code creates a new element (or say it smart), then close the Studio application from the workspace and re-open it by double-clicking app.callflow and the new element will appear under Elements/Local Elements.
To create the Java project, select New/Project/JavaProject/ Enter a name for your Java project and click 'Next'.
Then in the wizard, click on the Libraries tab and click 'Add External Jars' - you'll need to select 'framework.jar', 'servlet.jar' (was called servlet2.3.jar until cvp 9), and if you're extending existing studio elements you'll need 'elements.jar' - do a Search ahead of time, these files are all in the Studio/eclipse/plugins folder somewhere.
Then copy some of the Cisco examples into your Java project. Eclipse will compile. You can then copy the compiled class files into your Studio application and test them (as described above).

Assuming the class is compiled correctly and there are no errors, I would bundle it into jar and deploy it under the lib dir. JDK is not an issue.

Once you close the app out of the Studio workspace, and then
double-click app.callflow, the element should show up under Local
Elements. If it doesn't then there's usually an array indexing problem
in your java code.
In Studio, look under Window > Show View > Call Studio Error Log. This
will display at the bottom of the Studio window, near the Studio
Problems tab. You should select the error, and right-click, select
Properties. This will pop up a box and give you an error message and
Java stack trace.
Usually the error is in the method named GetSettings or GetElementData
or GetExitStates. Each of these has an array. You must specify the size
of the array. And then you MUST initialize each row of the array.
If you either fail to initialize one of the array rows, or if you
initialize a row of the array but the array dimension is smaller than
that (indexOutOfBounds) then the element will fail to show up in the
Studio pane.
Feel free to post your java file online and I'll fix it for you.

This is a 'Standard Action' - it doesn't show up as a new element in
Studio.
To use this code, you drag in the Studio element named 'Action'. You can
then name the element in Studio if you like.
In the right side, configuration pane, enter the Java class name
(without a file extension) - 'TEST1' (omit the quotes).
That's all.

Hi Mark
For the audium element to show up in the studio, you will have to implement the ElementInterface in your class. Apart from CVP programming guide, you will also need the javadoc for CVP API. You can download some sample custom elements and the javadocs from http://developer.cisco.com/web/cvp/home

Janine,
We are trying to create a custom element that will call a REST web service and return the results. We have created the custom element that shows up in builder if we don't have the web service java included but it fails when the web service java is added. To try to troubleshoot, we created a "scriptlet" with just the web service code but it fails with an error that seems to relate to version. The code and jar files we used are below...do you have any suggestions? We have tried to confirm versions are compatible with the jar files we are using but we still receive the error. Is there a better/simpler way to do this web service post? Thank you for your assistance!

Jersey 1.5 requires Java 6 by default, so it won't work in CVP versions prior to 9.0, which introduced Java 6 support. You can try rolling back to Jersey 1.2, which supports Java 5, or try recompiling the Jersey source code in Java 5. You should also confirm that the other libraries support Java 5. Alternatively you can skip Jersey altogether and do your REST lookup with basic HTTP client code.

Thanks Ed! That solved the unsupported version error but now the element won't load. We get the below error in the audium.log after restarting CallStudio:

In googling, we have found several suggested jar files but none of them have solved the issue.
We can run the java and get results back in the console, but when we implement the code in the custom element, we receive the above error.
Has anyone seen this error or have any suggestions?

That class should be in the Jersey jar files. Open up the jar files and see if it's in there. If not something is wrong with the library you downloaded, or you are missing a required Jersey library. If it's there, make sure it's loaded where CVP can see it (in the project lib folder or the common lib folder) and reopen the script or restart Call Studio as necessary to make sure it's loaded.

Janine Graves:Once you close the app out of the Studio workspace, and then
double-click app.callflow, the element should show up under Local
Elements. If it doesn't then there's usually an array indexing problem
in your java code.
In Studio, look under Window > Show View > Call Studio Error Log. This
will display at the bottom of the Studio window, near the Studio
Problems tab. You should select the error, and right-click, select
Properties. This will pop up a box and give you an error message and
Java stack trace.
Usually the error is in the method named GetSettings or GetElementData
or GetExitStates. Each of these has an array. You must specify the size
of the array. And then you MUST initialize each row of the array.
If you either fail to initialize one of the array rows, or if you
initialize a row of the array but the array dimension is smaller than
that (indexOutOfBounds) then the element will fail to show up in the
Studio pane.
Feel free to post your java file online and I'll fix it for you.
Janine,
We are trying to create a custom element that will call a REST web service and return the results. We have created the custom element that shows up in builder if we don't have the web service java included but it fails when the web service java is added. To try to troubleshoot, we created a "scriptlet" with just the web service code but it fails with an error that seems to relate to version. The code and jar files we used are below...do you have any suggestions? We have tried to confirm versions are compatible with the jar files we are using but we still receive the error. Is there a better/simpler way to do this web service post? Thank you for your assistance!

You can't run jersey 1.5 in CVP 8x, Jersey requires Java 6 which is only supported as of CVP 9. The simpler method would be to ditch Jersey and just use the standard Java API (http://www.mkyong.com/java/how-to-send-http-request-getpost-in-java/) to make your HTTP requests. You can still use a JSON parser to parse the results; that library should be easier to get working than a full web service library.
