Hi Dean,
I have created a "common" procedure that I use when working with Java
strings.
When invoking a Java method I use something like the below. This sample is
calling the "setter" of an instance variable in my Java class. It requires
a "String" to be passed into the method, so I use my procedure newString()
to set the variable up correctly.
setIpAddress(pCsv: newString(pIpAddress));
In your example, it would be something like the below. Set up the class
name in the D-specs to make things easier when referring to the class. I
am guessing a bit based on what I read in your post, so you may need to
experiment a bit.
D className c '
cincom.eloquence.exits.gsm.token.UniversalToken'
To invoke the method, use your procedure that you have now prototyped
using WDSC.
getUniversalToken(className, newString(Mykey), newString(expireMinutes))
The prototype for my function looks like this:
D jStrConst c 'java.lang.String'
D newString pr O class(*java: jStrConst)
D pString 32767a const
And my module looks like this. Change the error handling routine to match
your own requirements.
/**
* newString()
*
* @descr Create Java string object.
* @usage newString("Text");
* @param pString Text string to initialise the String object.
* @return Java string object.
*/
P newString b export
D newString pi o class(*java: jStrConst)
D pString 32767a const
D string s o class(*java: jStrConst)
D error ds likeds(Error_Info) inz
// Local prototype to build a java "String" object (using
java.lang.String)
D newJavaString pr o extproc(*java: jStrConst:
D *constructor)
D class(*java: jStrConst)
D parm 32767a const
// Local prototype to java "trim" method (using java.lang.String.trim)
D trimString pr o extproc(*java: jStrConst: 'trim')
D class(*java: jStrConst)
/free
monitor;
string = newJavaString(%Trim(pString));
return trimString(string);
on-error *All;
error = Error_catch();
Error_throw(
'XCOMMON_001'
: 100
: 'newString'
: error.code + ': ' + error.text);
endmon;
/end-free

Calling Java from RPG take 2
Sent by:

In order to interface with some third party software, I need to call some
Java code that they provided to generate a token. My experience with Java
is mainly what I have read in articles. The statement they gave me was
String tokenValue = cincom.eloquence.exits.gsm.token. UniversalToken.
getUniversalToken(Mykey, expireMinutes)
Mykey is a java string and the expireMinutes is an integer. Thanks to the
previous thread about calling Java, I used the wizard in WDSC to create
the prototypes for calling the Java method. Thanks Joe! What I am
struggling with is how do I move data between a Java string variable and
an RPG character variable? I am guessing I need to create a new instance
of the Mykey field and somehow assign a value to it. I need to do this
with the Mykey field and the tokenValue field.
