Hi tom,
Which types of variable are u talking about? You can only pass localenvironment,environment variable from node to node..

Okay, in the esql node, put that string variable into the LocalEnvironment tree and then you can access that from the java compute node.

Set the string in environment variable in ESQL node..
Access it from Java compute node. If it is local environment variable then..
| Code: |
MbMessage env = assembly.getLocalEnvironment();
MbMessage newEnv = new MbMessage(env);
--- do processing here
MbMessageAssembly outAssembly = new MbMessageAssembly(
assembly,
newEnv,
assembly.getGlobalEnvironment(),
assembly.getExceptionList(),
assembly.getMessage());
getOutputTerminal("out").propagate(outAssembly); |
If it is a global environment do ..
| Code: |
| MbMessage env = assembly.getGlobalEnvironment(); |

do a search in the broker's info center for "getLocalEnvironment", there's several pages of info that should be helpful.
