Service Virtualization

Hi ,

I am trying to execute a java code that add extra space on the right side, if a string is not of defined width.

code is:

//right padding

HOST_PROCESS_ID = String.format("%-" + 8 + "." + 8 + "s", HOST_PROCESS_ID);

or

HOST_PROCESS_ID = HOST_PROCESS_ID.format("%-" + 8 + "." + 8 + "s", HOST_PROCESS_ID);

this is giving me exception in vsm(data protocol) and in vsi(matchscript).

Please let me know if we can handle this by some other way as well.

Why this: #calisa when encounter a series of spaces before or after a string in incoming request(#lisa_vse_request) , it applies trim on the string. Hence I have to add padding exclusively to get my string of original length.

Please help, It's urgent.

Thanks,

Dinesh Kumar

Hi,

More Info:

When executed using 'Java Script Step(deprecated)' or from 'Java Script Step JSR-223' giving below error:

============================================================================
| Error in Script
============================================================================
| Step:        Execute script (JSR-223)
----------------------------------------------------------------------------
| Message:     Sourced file: inline evaluation of: ``import com.ca.sv.devtest.util.GenerateString; // Right-click to insert a sample  . . . '' : Error in method invocation: Method format( java.lang.String, java.lang.String ) not found in class'java.lang.String

Thanks,

The exception gives the reason why the code is failing. The String.format method takes two input arguments (java.lang.String, java.lang.Object)

https://docs.oracle.com/javase/7/docs/api/java/lang/String.html#format(java.lang.String,%20java.lang.Object...)

Please retry after casting the second argument to java.lang.Object

Hi Dinesh,

Try this:

HOST_PROCESS_ID = String.format("%-8.8s", HOST_PROCESS_ID);

When you tried to concatenated '8' it used the character with an ASCII value of 8 - not a textual '8'.

Hi Mike and Prem,

I still getting exception in ca lisa, while same code is working fine in eclipse.

code:

Hello Dinesh,

If you add the following lines in a JSR 223 step of DevTest 9.5, it works fine - there are no errors.

String IBC_MESSAGE_FORMAT= "RNBP";

 IBC_MESSAGE_FORMAT = String.format("%-8.8s", IBC_MESSAGE_FORMAT);

return IBC_MESSAGE_FORMAT;

Can you share the complete code of your VSM/VSI ? What is the version of DevTest you are using?

Yes you are right,

This is working fine in 9.5.1

but I am currently working on v8.0.1 registry. facing error in this version.

Thanks,

Hi Dinesh,

In that case, I know what the problem is.  That version of DevTest uses a BeanShell library that only supports JDK v1.4.  The String.format() method was introduced in JDK v1.5.

Use something like this instead:

IBC_MESSAGE_FORMAT = (IBC_MESSAGE_FORMAT + "        ").substring(0,8);

Hi Mike,

Thank you for the workaround. I have implemented a similar solution as below:

1- Compare the incoming string with the original defined length.

2- Add the difference with space character(" ") using for loop.

Thanks,

Dinesh Kumar
