I am using SAPJco3.jar for connecting to SAP using Java. However, when I am trying to stop my bridge, I get some error.
The code for disconnection is this :
public void tearDown() {
log.info("tearDown() | Starting tear down ...");
log.info("tearDown() | Stopping {} JCO servers ...", jcoServerList.size());
System.out.printf("\ntearDown()| Stopping %s JCO servers ...", jcoServerList.size());
System.out.println();
for (JCoServer jcoServer : jcoServerList.values()) {
try {
jcoServer.stop();
jcoServer.release();
} catch (Exception e) {
log.error("Failed to STOP JCO server {} e={}", jcoServer.getProgramID(), e.toString());
}
}
jcoServerDataManager.clearAllData();
jcoServerDataManager = null;
log.info("tearDown() | Done with tear down!");
}
The error JCO_ERROR_CONCURRENT_CALL I get is this :

When I am trying to stop the bridge, already there are some connections alive for this bridge and the status of the jcoserver changes from ALIVE -> STOPPING and it never goes to STOPPED. If there are no connections attached to the server, it goes to the status STOPPED without any problem.
Could any one please provide any direction for this problem? Is there any way I can forcefully stop the bridge?
Thanks!
