Java 101,

How do I convert a java string to a 400 alpha field?

Can you give a bit more context to your question? What are you going to do with the 400 alpha field when you get it?

And where are you going to "convert" it? Is this all to be done in Java? Or is this a value that is passed to some other program? (What program?) Why do you think it's not already a "400 alpha field"? Some additional explanation of the problem would help us know how to answer your question.

Im retrieving data from a web service and I want to write it a DB.

Thank You very much for all your help. Ive used your RPG "casting" example many times.

You shouldn't need to convert it before writing it to a DB... the JDBC driver should automaticalyl convert Java strings. Unless you're writing it using some other method?

Im using RPG to call a java webservice. It's returning a string object. I need to update that string object into an i5 alpha field to display on a cgidev2 browser screen and update it into a DB.

Web services return data in XML. When you parse the XML on the RPG-side, you will have an alphanumeric string, not a String object. No special conversion should be needed.

It's a restful service, it's returning a json string that is being parsed in the java program and the java return statement is returning a string

How are you calling the Java program? Via the RUNJVA command? Via JNI (extproc with *java)? Via APIs? Via the Java PCML tools? Another method?

Via JNI,


C eval mapString =
C new_String('sdk_config.properties')
C eval oauth = new_OAuthTokenCredential
C (clntString: scrtString)
C eval json = getAccessToken(oauth)

For JNI I would do something like this:

D getBytes        pr         32767A   varying            
D                                     extproc(*JAVA:     
D                                     'java.lang.String':
D                                     'getBytes')        
 ..                                       
    RpgAlphaVar = getBytes(javaStringObj);
