I'm trying to add a control when there is a connection error. My aim is to stop the program from throwing Exception by catching it.
try {
Client client = ClientBuilder.newBuilder()
.register(JacksonFeature.class)
.build();
client.register(new HttpBasicAuthFilter("login", "password"));
WebTarget webTarget = client.target("http://path");
Response response = webTarget.request().post(Entity.json(bean));
System.out.println(response.getStatus());
} catch (Exception e) {
// I do nothing here
}
But it prints in the console:
org.glassfish.jersey.client.ClientRequest writeEntity Grave: Error while committing the request output stream. java.net.ConnectException: Connection refused: connect at java.net.DualStackPlainSocketImpl.connect0(Native Method) at java.net.DualStackPlainSocketImpl.socketConnect(DualStackPlainSocketImpl.java:79) at java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) at java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:200) at java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) at java.net.PlainSocketImpl.connect(PlainSocketImpl.java:172) at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) at java.net.Socket.connect(Socket.java:579) at sun.net.NetworkClient.doConnect(NetworkClient.java:175) at sun.net.www.http.HttpClient.openServer(HttpClient.java:432) at sun.net.www.http.HttpClient.openServer(HttpClient.java:527) at sun.net.www.http.HttpClient.(HttpClient.java:211) at sun.net.www.http.HttpClient.New(HttpClient.java:308) at sun.net.www.http.HttpClient.New(HttpClient.java:326) at sun.net.www.protocol.http.HttpURLConnection.getNewHttpClient(HttpURLConnection.java:996) at sun.net.www.protocol.http.HttpURLConnection.plainConnect(HttpURLConnection.java:932) at sun.net.www.protocol.http.HttpURLConnection.connect(HttpURLConnection.java:850) at sun.net.www.protocol.http.HttpURLConnection.getOutputStream(HttpURLConnection.java:1091) at org.glassfish.jersey.client.HttpUrlConnector$3.getOutputStream(HttpUrlConnector.java:287) at org.glassfish.jersey.message.internal.CommittingOutputStream.commitStream(CommittingOutputStream.java:198) at org.glassfish.jersey.message.internal.CommittingOutputStream.commitStream(CommittingOutputStream.java:192) at org.glassfish.jersey.message.internal.CommittingOutputStream.commit(CommittingOutputStream.java:260) at org.glassfish.jersey.message.internal.OutboundMessageContext.commitStream(OutboundMessageContext.java:822) at org.glassfish.jersey.client.ClientRequest.writeEntity(ClientRequest.java:451) at org.glassfish.jersey.client.HttpUrlConnector._apply(HttpUrlConnector.java:290) at org.glassfish.jersey.client.HttpUrlConnector.apply(HttpUrlConnector.java:203) at org.glassfish.jersey.client.ClientRuntime.invoke(ClientRuntime.java:215) at org.glassfish.jersey.client.JerseyInvocation$1.call(JerseyInvocation.java:634) at org.glassfish.jersey.client.JerseyInvocation$1.call(JerseyInvocation.java:631) at org.glassfish.jersey.internal.Errors.process(Errors.java:315) at org.glassfish.jersey.internal.Errors.process(Errors.java:297) at org.glassfish.jersey.internal.Errors.process(Errors.java:228) at org.glassfish.jersey.process.internal.RequestScope.runInScope(RequestScope.java:426) at org.glassfish.jersey.client.JerseyInvocation.invoke(JerseyInvocation.java:631) at org.glassfish.jersey.client.JerseyInvocation$Builder.method(JerseyInvocation.java:391) at org.glassfish.jersey.client.JerseyInvocation$Builder.post(JerseyInvocation.java:300) at com.saintgobain.sg4p.igquality.desktop.DesktopClientController.sendToServer(DesktopClientController.java:857) at com.saintgobain.sg4p.igquality.desktop.DesktopClientController.handleSendToServerClicked(DesktopClientController.java:835) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at sun.reflect.misc.Trampoline.invoke(MethodUtil.java:75) at sun.reflect.GeneratedMethodAccessor1.invoke(Unknown Source)
If I add in the catch part: e.printStackTrace();
The console prints moreover:

Sorry if I prints too much stacktrace...
I'd like to know if I don't print out the stacktrace, how can I make the exception disappear? Thanks :)
