Hi All,
I have a java (JCN node) implementation in my Broker code which is working fine on my local broker environment.
However, I am facing an issue when I am deploying it to the development environment for which the runtime broker is on UNIX platform.
Below is the exception:
"BIP4395E: Java exception: 'java.lang.ClassNotFoundException'; thrown from class name: 'java.net.URLClassLoader$1', method name: 'run', file: 'URLClassLoader.java', line: '199'
The message contains that data associated with a Java exception.
No user action required."
I somehow feel that this is an issue related to the runtime broker environment and thus should work fine if the broker on the UNIX platform is checked for this possible cause.
Please let me know if someone has come across this kind of situation.

nthepak,
The broker uses the following search path to find JavaCompute node classes:
1. The deployed JAR file
2. <WorkPath>/shared-classes/ to locate any JAR Dependencies.
3. The CLASSPATH environment variable
You should try placed the jar files that you need in the shared-classes directory. |

Hi,
Yes, i have deployed the jar file which has the java implementation. Its like, when you add a JCN node to your flow the broker by default creates a Java project. I have deployed this Jar file also.
I think, by the exception that I am getting that, the runtime broker is not able to find any of the core java classes before JRE invokes my java implementation. Below is the exception that I am getting while running the Debugger:

| Which JDK did you build your JAR file with? Is it possible there is some incompatibility between a JAR built with the Sun JDK versus the IBM JRE? |

Could it be a problem with the file permissions on the jar file?
ls -al against the directory where your jar is should tell you if the broker user can access the file. |

Your code and exception does not tell much.
Here is a rule of thumb you ought to know.
When deploying a JCN or java project:
If you change a class name
either clear the eg before deploying
or make sure that the deployable contains, on the first deploy, both the old and the new class.
Hope that helped.
