Adding custom (user defined) java code - "cannot be resolved" error

vladika — Sat, 16 Nov 2024 13:10:14 GMT

Hi everyone,
I am trying to use user defined method in tJavaRow component in a job. It seems to me like I'm doing everything by the book ("TalendOpenStudio_UG_41b_EN.pdf", pages 267 to 272 in pdf), but I'm still getting "cannot be resolved" error when running a job.
This is my setup:
1. I've added the java code in Repository / Code / Routines / MyCode. I've created 2 methods: SqlINstr, SqlINnum and I kept the example helloExample code as well. Enclosed that in MyCode public class and tried to create all comments as required:

public class MyCode {
	
	/**
     * SqlINstr: Emulate SQL IN operator.
     * 
     * 
     * {talendTypes} boolean | Boolean
     * 
     * {Category} User Defined
     * 
     * {param} String("value") input: The string need to be printed.
     * 
     * {param} String[] ("value2","value3") pattern: The string array to match at least one.
     * 
     * {example} SqlINstr (String EntryValue, String[] MatchingConditions)
     * 
     */	
  public static boolean SqlINstr(String EntryValue, String[] CondSet) {
	    int cnt = 0;
	    boolean MatchFound = false;
	    while (cnt < CondSet.length) {
	      if (EntryValue.equals(CondSet)) {MatchFound = true;}
	      cnt++;
	    }
	    return MatchFound;
	  }
  
  /**
   * SqlINstr: Emulate SQL IN operator
   * 
   * 
   * {talendTypes} boolean | Boolean
   * 
   * {Category} User Defined
   * 
   * {param} Integer(1) input: The integer need to be printed.
   * 
   * {param} Integer[] (100, 101) pattern: The integer array to match at least one.
   * 
   * {example} SqlINnum (int EntryValue, int[] MatchingConditions)
   * 
   */ 
  public static boolean SqlINnum(int EntryValue, int[] CondSet) {
      int cnt = 0;
      boolean MatchFound = false;
      while (cnt < CondSet.length) {
	if (EntryValue == CondSet) {MatchFound = true;}
	cnt++;
      }
      return MatchFound;
    }
    /**
     * helloExample: not return value, only print "hello" + message.
     * 
     * 
     * {talendTypes} String
     * 
     * {Category} User Defined
     * 
     * {param} string("world") input: The string need to be printed.
     * 
     * {example} helloExemple("world") # hello world !.
     */
    public static void helloExample(String message) {
        if (message == null) {
            message = "World"; //$NON-NLS-1$
        }
        System.out.println("Hello " + message + " !"); //$NON-NLS-1$ //$NON-NLS-2$
    }
}

2. I've added the code in tJavaRow component to use those methods:

String[] AcrGL = {"DND","DOD","SPD","VAG"};
if (SqlINstr(input_row.acr, AcrGL)) 
	{output_row.saldorsd_gl = input_row.saldorsd;}

But, when I run the job I'm getting: "MyCode cannot be resolved" error? Is this because of some error in the code, or I didn't specify enough where the application should look fot the code?
Thanx.

You must precise the package when you call your routine. Just type "Routine" and CTRL+Space for autocompletion you should get full path to your method.

Ok, I've modified now tJavaRow with the following:

String[] AcrGL = {"DND","DOD","SPD","VAG"};
if (Routines.MyCode.SqlINstr(input_row.acr, AcrGL)) 
	{output_row.saldorsd_gl = input_row.saldorsd;}

But I am still getting the same error. When I type CTRL+SPACE after typing "Routines." for autocompletion all I get is an empty window with the header: No basic/template/swt proposals?

Aaah.. It's case sensitive.. Sorry it works allright! (It's "routines" instead of a "Routines")
Muchos gracias camsellem.

Hi, I'm having the same problem here...
There is no typo error or case sensitive.
I didn't even write into the code manually.
I added it into the expression filter.
and in expression filter, my method is visible and available.
but when i tried to run the job, it gave me that MyMethod cannot be resolved
I tried to import the class manually too....
Please.... tell me how can I fix this.....
Thanks

Right click on the job name and select 'set routines dependencies' option to check your custom routine is there, add it if not.
