How to create a Custom Response using Scripting option in Parasoft?

AvinashPanditi

Hi , I am new to Parasoft. I want knowledge on how to create a "Custome Response" using Scripting. I see the tool is having an option "Scripted" in the Response Tab--> Input Mode to generate a Response by writing code using Java or a Groovy or some other language mentioned.

If someone can provide me a small example or a Case Study or a Tutorial it will be great and it will help me a lot. Thanks in Advance. You can share me a link here or can send me a mail over to my Personal Mail Id: avinash246891@gmail.com

If someone can provide me a small example

Like this?

Groovy:

import com.parasoft.api.*

String foo(ScriptingContext context) {
    return "hello world"
}

Jython:

from com.parasoft.api import *

def foo(context):
    return "hello world"

Hi Benken, Thanks for the response. I have written a java code which will generate an XML message as output. I have made a Jar file with the code and added the Jar file to the class path by clicking on the "Modify Classpath" in the "Response Tab". When i tested i could see the below error in the Events Log. Please help me with this issue. I have tested this by deploying the Virtual Service to "Parasoft Server". Should i need to place this jar file to "Parasoft Server".

Test Name: 1. JSON Message Responder
Source: JSON Message Responder
Message: com.parasoft.api.UserMethodException: CreateXML

Hi,

When you say Parasoft Server do you mean the "local" server in your desktop? Or a remote server hosted somewhere else? If the server is not the "local" server in your desktop then yes you will need to add the jar to its class path.

To make it easier to deploy your asset without needing the extra jar you could try using the Groovy scripting language. You can probably almost use the same code from your Java jar in groovy with a few minor changes.

Hi William, Thanks for the reply. I am testing the Virtual Service by deploying the to remote server. Is there a way to add the class file instead of Jar, since I am comfort with Java coding. Is there a way along with the Virtual Service deployment we can add the jar or a class file to the remote server.

williammccusker

Hi,
There isn't a way that I know of to deploy just the class file. To deploy the jar file to the remote server upload it into the remote servers "Virtual Assets" project into a folder named "system_jars"

After the jar file is uploaded (and before the virtual asset is deployed) you should trigger the rest api resource that reloads the "System Properties" which will load your uploaded jar file.

curl -X POST -O http://timewarp:9080/soavirt/api/v6/preferences/systemProperties/reload

Then you can upload your virtual asset and it should load your custom code from the jar file.

Thanks Will for the info. I checked the Parasoft tool --> "Virtual Server" section and i don't see an option to upload the jar file to the Parasoft remote server. I could see a folder "system_jars", i don't see an option to upload jar file.

Hi,

In the server view expand the "Files" or "Workspace Files" under the remote server. Expand the tree until you see the "system_jars" folder. Then drag the jar file from you local workspace and drop it into the "system_jars" folder.

AvinashPanditi

I dragged the Jar file but its not getting copied to system_jars folder under "Workspace Files" folder. I am doing this to the Remote Server view which is visible in the tools "Virtual Server" section (Middile Right corner of tool)

williammccusker

Hi,
Are you dragging from the Navigator view to the Virtualize Server view? It works when I do that. Make sure you're not accidentally dropping it onto the folder under the "Virtual Assets" node in the server view because that will not work.

Here is a screenshot of where I placed the test jar file. In this case I copied it to a remote server into a folder named "bill"

AvinashPanditi

Thanks will, i will try this on Monday and will let you know the results.

Hi William, I was able to place the jar file to the system_jars of Remote server. I have triggered the REST API resource by replacing the hostname and port number of the remote server which we are using in our project.

http://timewarp:9080/soavirt/api/v6/preferences/systemProperties/reload

Theres no response for the REST API POST call instead got a blank response with following headers.

HTTP/1.1 204 No Content
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
Access-Control-Allow-Headers: Content-Type, Accept, Authorization
Date: Mon, 06 Jan 2020 15:09:02 GMT
Connection: close
Server: Parasoft Server

When tested getting the following error which i have mentioned in my other question earlier.

Message: Unable to instantiate class "oracle.jdbc.driver.OracleDriver". Please check the DB driver classname and the jar file locations in Parasoft > Preferences > JDBC Drivers.: 08001

Could you please help here. Thanks.

williammccusker

Hi,
Is the driver jar also deployed to the remote virtualize server? I think it can be deployed to the same way, to system_jars, but I am not sure if it will require the server to be restarted to pick up the JDBC Driver. I would start by making sure that JDBC Driver jar is uploaded to system_jars and try using the reload rest api (the 204 response code means it reloaded successfully).

AvinashPanditi

Hi William, I will try to get the server restarted and see if that works. Thanks.

Parasoft is installed in a Linux based Remote server, Can you share us the path where we can directly place the Jar files in the server.

williammccusker

Hi,
It doesn't have a default location so you will have to contact who ever setup the server on the Linux machine since they would know where they installed it.

AvinashPanditi

Hi William, Parasoft Server admin team has place the "ojdbc" jars in the server and restarted the server, but still DB tool is failing with the below error. Any idea how to solve this issue as we need this issue to be solved in a week time.

Message: Unable to instantiate class "oracle.jdbc.driver.OracleDriver". Please check the DB driver classname and the jar file locations in Parasoft > Preferences > JDBC Drivers.: 08001

williammccusker

Hi,
It should work from the system_jars directory. I tried a test case and I was able to get a db connection using a driver jar that I put into system_jars. Does the Oracle ojdbc jar have that driver class?

AvinashPanditi

Hi William, same Jar file is loaded in Local Machines and it works, only issue with the remote server.

williammccusker

Do you know if the remote server is a war deployment of a virtualizecli? It's possible that if it is the virtualizecl that you will need someone to setup the JDBC Driver similar to how it gets configured on the local machine.

AvinashPanditi

Hi William, Yes, we are using a Linux machine. And it execute via virtualizecli. we try copying JDBC file lib directory and also System_jar directory.

FYI., we are running virtualizeclie with Zjava attribute

williammccusker

Hi,
I am not sure what the "Zjava" attribute is. Also just to make sure the directory is named "system_jars" all lower case and with the 's' at the end.

jakubiak

@williammccusker - -Zjava_home is how you tell virtualizecli to use a specified Java installation.

@AvinashPanditi I'm new to Parasoft and I don't know how to add my java project to the classpath as mentioned in Extensibility and Scripting Basics
Even ,when i select the 'Scripted' mode from 'Input mode' of Response tab I could see my 'Modify Classpath' Feature is disabled neither I'm able to type in the text editor that appears. I have Free Community Edition, is this feature not available for free community edition?

Thank you in advance.
