Hello everyone,

this is my first post in here, I'm new in message broker development.

i need to generate random alpha numeric in java.

i created a simple flow to simulate generating the alpha numeric:

HTTP input -> compute node -> trace node -> HTTP reply

I've created below java class

Code:

package baj.sadad.helper;

public class SADADHelper
{
   private static final String ALPHA_NUMERIC_STRING = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
   
   public static void main(String[] args)
   {
      System.out.println("random Alpha Numeric = " + randomAlphaNumeric());
   }
   
   public static String randomAlphaNumeric()
   {
      StringBuilder builder = new StringBuilder();
      
      int stringLength = 6;
      
      while(stringLength-- != 0)
      {
         int character = (int)(Math.random() * ALPHA_NUMERIC_STRING.length());
         
         builder.append(ALPHA_NUMERIC_STRING.charAt(character));
      }
      
      return builder.toString();
   }
}


and create the jar as below

Code:

D:\Java\ibm_sdk80\bin>jar cvf  bajsadadhelper.jar  baj
added manifest
adding: baj/(in = 0) (out= 0)(stored 0%)
adding: baj/sadad/(in = 0) (out= 0)(stored 0%)
adding: baj/sadad/helper/(in = 0) (out= 0)(stored 0%)
adding: baj/sadad/helper/SADADHelper.class(in = 1100) (out= 702)(deflated 36%)


added the created jar in /var/mqsi/shared-classes/ (work path)

when trying to call the java function from below ESQL snippet it returns below error actually when accessing compute node.

ESQL snippet:

Code:



CREATE COMPUTE MODULE LocalApplication_MSGFlow_Compute
   CREATE FUNCTION Main() RETURNS BOOLEAN
   BEGIN
      CALL CopyEntireMessage();
      
      DECLARE randomAlphaNumeric1 CHARACTER;
      DECLARE randomAlphaNumeric2 CHARACTER;
      
      CALL randomAlphaNumerics() INTO randomAlphaNumeric1;
      
      IF randomAlphaNumeric1 IS NOT NULL OR randomAlphaNumeric1 <> '' THEN
         SET randomAlphaNumeric2 = randomAlphaNumeric1 || ' Generated randomAlphaNumeric';
      ELSE
         SET randomAlphaNumeric2 = 'randomAlphaNumeric IS NULL';
      END IF;
      
      RETURN TRUE;
   END;

   CREATE PROCEDURE CopyEntireMessage() BEGIN
      SET OutputRoot = InputRoot;
   END;
   
   CREATE FUNCTION randomAlphaNumerics()
   RETURNS CHARACTER
   LANGUAGE JAVA
   EXTERNAL NAME "baj.sadad.helper.SADADHelper.randomAlphaNumeric";

END MODULE;

i need support there how to make the broker see the JAR file from shared classes path .

hi...what is this random number used for? see whether UUIDASCHAR fits the bill, if so you can do this in ESQL itself.

https://www.ibm.com/support/knowledgecenter/SSMKHH_10.0.0/com.ibm.etools.mft.doc/ak05910_.html

Coming back to class not found error, check the below,
- Just to be sure do verify that the node is indeed using '/var/mqsi' as Workpath...use mqsireportbroker to verify that.
- check the file permissions to ensure that broker user id to have the sufficient permissions
- After loading the jars to the shared-classes did you restart the integration node?

hi, this random number will be used internally when calling other systems through SOAP request (part of the message body) or MQ input (part of the message which we put) which should have dynamic length and could be longer than what UUIDASCHAR generates.

1- I ran the command and it returned to me "Work path = '/var/mqsi'"
2- the file permission is the same as other files "-rw-r--r--"
3- I tried first without restart then restart the broker and the same error received

- is the file owner the same as the broker user id or just try changing the permissions to 755 and see?
- is /tmp full at all and does broker user id have sufficient permissions to read/write to it.
- enable user trace for the flow and post the full error details here
- what happens if you deploy the jar file directly via the same message flow bar file

before the trace details, i wanna highlight something:

before the MB was using root user with full privileges
and due restriction from application security team they force us to create new user ano not to use the root user.

we created different user and put user id in mqbrkrs and mqm groups
now the broker and running with the new user.


trace log contain $root and $exception list

hi...so the integration node was created using root and later switched to be started/running as a different user? I wonder whether that might be contributing to the issue, usually IIB installation as such is done by a superuser but nodes are created using specific users.

Did you ran the 'iib verify all' or 'ace verify all' after switching to the new user, not sure whether it will verify classpath access though.

You could try creating another temporary integration node using the new user and see whether the java call works there. Alternatively you could collect service trace of integration server and trace the error there, just to see whether the broker is looking at the right folders for the classes.
