Hi,
I have a problem running my app that implements webservice using Provider api.
After ~4hrs of mild load AS goes out of memory.
I'm using JBoss 5.0.1 with sun jdk 1.6.0_14. Configuration is
-Xms256m -Xmx1024m -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true
-XX:+UseConcMarkSweepGC -Dsun.rmi.dgc.client.gcInterval=1800000
-Dsun.rmi.dgc.server.gcInterval=1800000
My endpoints defined as follows:
| @WebServiceProvider(serviceName = "StorageService", portName = "External",
wsdlLocation = "WEB-INF/wsdl/storage.wsdl")
| @BindingType(value = HTTPBinding.HTTP_BINDING)
| @ServiceMode(value = Service.Mode.PAYLOAD)
| public class StorageServiceExternalProvider extends AbstractServiceProvider
implements Provider<Source> {
|
| @Resource(type = Object.class)
| protected WebServiceContext wsContext;
|
| public Source invoke(Source req) {
| MessageContext mc = wsContext.getMessageContext();
| String path = ((String)
mc.get(MessageContext.PATH_INFO)).substring(1);
| return invoke(path, req);
| }
|
| protected String getJndiNameSLSB() {
| return "StorageExternalSarco/local";
| }
| }
|
|
| public abstract class AbstractServiceProvider {
| private static Logger log = Logger.getLogger(AbstractServiceProvider.class);
|
| protected abstract String getJndiNameSLSB();
|
| public Source invoke(String path, Source req) {
|
| JAXBContext jc = null;
| Object local;
| Method[] localMethods;
|
| try {
| InitialContext ic = new InitialContext();
| local = ic.lookup(getJndiNameSLSB());
| ic.close();
| localMethods = local.getClass().getMethods();
|
| jc = StorageJAXBContext.getContext();
|
| } catch (Throwable t) {
| log.error("Unable to initialize", t);
| return new DOMSource();
| }
|
| Reader decoded;
| Object in = null;
| try {
|
| decoded = new
StringReader(URLDecoder.decode(req.toString(), "utf8"));
| in = jc.createUnmarshaller().unmarshal(decoded);
|
| if (in instanceof JAXBElement<?>)
| in = ((JAXBElement<?>)in).getValue();
|
| for (Method m : localMethods)
| if (m.getName().equals(path))
| {
| Object result = m.invoke(local, in);
| Class<?> retType = m.getReturnType();
| if (retType == Void.TYPE)
| return new DOMSource();
| else
| return new JAXBSource(jc,
result);
| }
|
| throw new Exception("Accessing invalid path: " + path);
|
| } catch (Throwable e) {
| log.error("Error processing invocation for path: " +
path + ", input type is: " + (in == null ? "NULL" : in.getClass()), e);
| return new DOMSource();
| }
| }
|
web.xml:
<servlet>
| <servlet-name>StorageServiceExternalProvider</servlet-name>
|
<servlet-class>com.photoholding.storage.StorageServiceExternalProvider</servlet-class>
| </servlet>
| <servlet-mapping>
| <servlet-name>StorageServiceExternalProvider</servlet-name>
| <url-pattern>/External/*</url-pattern>
| </servlet-mapping>
I tried to do jmap profiling and it shows lots of B[ and C[ objects growing
with time. Looks like "Provider" instance is never released and GC skips it -
size of the OldGen grows until GC can't handle it.
Any help is appreciated.
