Hi All,
I am just trying to implement the shared library concept in our IIB v10.0.0.7. I am getting error while deploying the application into integration server. Following things I did so far, implementing the Shared Library Concept.
1. Created a simple Java Project with one static function.
| Code: |
package com.test;
public class Test {
public static String greeting(){
return "Hello";
}
}
|
2. Create a shared Library name: ShaLIB and provided the project reference of Java Project.
3. Deployed the shared Library into integration server and it was deployed successfully.
4. Created a Application named "ShaAPP" with one simple flow.
HTTPInput--->Compute--->HTTPReply
5. In Compute Node, I am trying to Access the greeting() function using ESQL code.
| Code: |
CREATE FUNCTION greeting()
RETURNS CHARACTER
LANGUAGE JAVA
EXTERNAL NAME "com.test.Test.greeting"
CLASSLOADER "{ShaLIB}";
|
6. Now I am trying to deploying the application into integration server, I am getting following error. Tried with reference of Shared Library and without shared library.

Review related error messages to determine why the administration request failed.
BIP3202E: (.greeting, 1.1) : An error occurred when trying to resolve the Java class or method 'com.test.Test.greeting' which is referred to by the routine 'greeting'.
Further messages are generated that explain the error in more detail.
Correct the syntax of your Java expression in node '.greeting', around line and column '1.1', then redeploy the message flow.
BIP1328E: The Java method 'com.test.Test.greeting' cannot be loaded because the ESQL definition specifies that the Java method must be loaded from the classloader for shared library 'ShaLIB'. The shared library 'ShaLIB' is not available.
The ESQL definition for the specified Java method specifies that the Java method must be loaded from a classloader for a shared library that is not available.
Check that the specified shared library exists and is deployed to the integration server. Also check that the application or shared library that contains the specified message flow references that shared library explicitly.

So please give me a hint where I am missing any thing?
Thanks in advance. |

Check back with your interfaces. I believe to be callable from ESQL your method needs to return String[] and not String.... Have fun

Hi Fjb_saper,
Thanks for your response. Same code was working as "static Library". So there is no issue in function definition.
The error says

Java must be loaded from class loader. I am searching in the information center about, how to load java using class loader. |
