I have a feeling I'm doing something very wrong with respect to passing a
reference to a log to a non-SEAM object. What happens (running under JBoss AS
4.0.5) is that the first time the non-SEAM object tries to use a log method all
log output from the container stops. The application keeps running, and in
fact I can remove and add the SEAM application in the deploy directory and have
it redeploy but still get no logging output.
Here is fragments of the code from the SEAM app. First, the SEAM-enabled
session bean.
| @Stateful
| @Name("search")
| @Scope(ScopeType.SESSION)
| public class SearchAction implements Search {
|
| @Logger
| private Log log;
|
| @In
| ParamStore paramStore;
|
| public String search() throws Exception {
| paramStore.setLog(log);
| log.info("search.search() action called with: #0", q);
| SearchSvc searchSvc = new searchSvc();
| List<String> matchingIds = searchSvc.search(paramStore, q);
|
Next, 'ParamStore' which holds the 'log' value. This is not an SEAM entity
bean (e.g., it does not have the @Entity annotation), just a normal JavaBean.
| public class ParamStore {
|
| private Log log;
|
| public ParamStor() { }
|
| public Log getLog() {
| return log;
| }
|
| public void setLog(Log log) {
| this.log = log;
| }
| }
|
And finally a non-SEAM object that tries to make use of it.
| public class SearchSvc {
|
| public List<String> search(ParamStore paramStore, String query)
| throws Exception {
|
| Log log=paramStore.getLog();
| log.warn("This'll never be seen. #0", "And subsequent log
messages are not seen.");
| }
| }
|
