• Unable to launch Eclipse 4.1.2 after installing the Eclipse e4 tooling

  After installing Eclipse e4 Tools in my Eclipse 4.1.2 from update site. I am getting error when launching the eclipse.exe "An error has occurred.

• Atomikos vs JOTM vs Bitronix vs ????

  - by HDave

  I am new to JTA and it's underlying transaction managers. Can anyone explain the pros/cons of each of these? Feel free to add others I didn't list in title. Also, don't the major applications servers (WebSphere, JBoss, Glassfish) have their own JTA compliant transaction manager? In those environments, would you still use these third party implementations?

• JSF a4j:commandButton not working when 'disabled' is set

  - by Jon

  Hello, When I include a 'disabled' attribute on an a4j:commandButton, the button's action is not performed. Taking the 'disabled' attribute out causes it to work properly. I am not doing any special validation (that I'm aware of) and am not seeing any validation error messages. Here is part of my page: <t:dataTable id="myTable" var="region" value="#{MyPageBackingBean.regions}" width="100%"> ... <a4j:commandButton value="Update" action="#{region.doUpdate}" oncomplete="alert('done');" disabled="#{!empty region && region.messageEmpty}" immediate="true"/> ... </t:dataTable> Any ideas? Thanks! Edit: I tried setting preserveDataModel="true" on the t:dataTable to no avail. I also made a test having an a4j:commandButton and text box with no data table, but the backing bean action is still not being fired: <h:form> <a4j:region> <a4j:outputPanel id="testregion"> <h:messages id="messages"/> <a4j:status> <f:facet name="start"> <h:graphicImage value="/images/progress_indicator.gif"/> </f:facet> </a4j:status> <h:inputTextarea rows="5" value="#{MyPageBackingBean.myValue}" style="width:100%; border: 1px solid #99CCFF;"> <a4j:support event="onkeyup" reRender="testregion" eventsQueue="messageModificationQueue" ignoreDupResponses="true" requestDelay="500"/> </h:inputTextarea> <a4j:commandButton id="doDelete" value="Delete" action="#{MyPageBackingBean.dummy}" reRender="testregion" disabled="#{empty MyPageBackingBean.myValue}"/> <h:outputText value="#{MyPageBackingBean.myValue}"/> </a4j:outputPanel> </a4j:region> </h:form> Here is the new backing bean code used for testing: private String m_myValue = null; public String getMyValue() { return m_myValue; } public void setMyValue(String value) { m_myValue = value; } private String mystr2 = null; public String dummy() { mystr2 = "hello"; return null; } Thanks!

• JSF - get managed bean by name

  - by Konrad Garus

  I'm trying to write a custom servlet (for AJAX/JSON) in which I would like to reference my @ManagedBeans by name. I'm hoping to map: http://host/app/myBean/myProperty to: @ManagedBean(name="myBean") public class MyBean { public String getMyProperty(); } Is it possible to load a bean by name from a regular servlet? Is there a JSF servlet or helper I could use for it? I seem to be spoilt by Spring in which all this is too obvious.

• JSF Page does not submit when onclick javascript is added to menu item?

  - by Padmarag

  I show some detail using popup windows. I want to close those when the user clicks on sign-out link. I have a JavaScript function that'll close the windows. The sign-out link is rendered using Navigation MenuModel. The definition in faces-config is as below - <managed-bean> <managed-bean-name>signoutNavigation</managed-bean-name> <managed-bean-class>com.xxx.xxx.framework.NavigationItem</managed-bean-class> <managed-bean-scope>none</managed-bean-scope> <managed-property> <property-name>label</property-name> <value>Sign Out</value> </managed-property> <managed-property> <property-name>viewId</property-name> <value>/signout.jsp</value> </managed-property> <managed-property> <property-name>outcome</property-name> <value>signout</value> </managed-property> <managed-property> <property-name>onclick</property-name> <value>closeOrderWindows()</value> </managed-property> </managed-bean> The problem is when I use the "onclick" property on managed-bean, the page doesn't submit to "signout.jsp" and remains on same page. When I remove/comment the "onclick" part, the page gets submitted properly. I use MyFaces Trinidad.

• Does writing data to server using Java URL class require response from server?

  - by gigadot

  I am trying to upload files using Java URL class and I have found a previous question on stack-overflow which explains very well about the details, so I try to follow it. And below is my code adopted from the sniplet given in the answer. My problem is that if I don't make a call to one of connection.getResponseCode() or connection.getInputStream() or connection.getResponseMessage() or anything which is related to reponse from the server, the request will never be sent to server. Why do I need to do this? Or is there any way to write the data without getting the response? P.S. I have developed a server-side uploading servlet which accepts multipart/form-data and save it to files using FileUpload. It is stable and definitely working without any problem so this is not where my problem is generated. import java.io.Closeable; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.OutputStream; import java.io.PrintWriter; import java.net.HttpURLConnection; import java.net.URL; import org.apache.commons.io.IOUtils; public class URLUploader { public static void closeQuietly(Closeable... objs) { for (Closeable closeable : objs) { IOUtils.closeQuietly(closeable); } } public static void main(String[] args) throws IOException { File textFile = new File("D:\\file.zip"); String boundary = Long.toHexString(System.currentTimeMillis()); // Just generate some unique random value. HttpURLConnection connection = (HttpURLConnection) new URL("http://localhost:8080/upslet/upload").openConnection(); connection.setDoOutput(true); connection.setRequestProperty("Content-Type", "multipart/form-data; boundary=" + boundary); OutputStream output = output = connection.getOutputStream(); PrintWriter writer = writer = new PrintWriter(output, true); // Send text file. writer.println("--" + boundary); writer.println("Content-Disposition: form-data; name=\"file1\"; filename=\"" + textFile.getName() + "\""); writer.println("Content-Type: application/octet-stream"); FileInputStream fin = new FileInputStream(textFile); writer.println(); IOUtils.copy(fin, output); writer.println(); // End of multipart/form-data. writer.println("--" + boundary + "--"); output.flush(); closeQuietly(fin, writer, output); // Above request will never be sent if .getInputStream() or .getResponseCode() or .getResponseMessage() does not get called. connection.getResponseCode(); } }

• spring security login pages?

  - by es11

  I have some confusion with how spring security works: In my application, I need to have a login page for users after which they are redirected back the page from where they came. I went through a few spring security tutorials and read some articles, and the examples work by securing a certain page on a site (managed by the <intercept url ..> tag). Then Spring security will generate a login page (or you can specify your own) in order to access the secured page. I am confused because I don't want to necessary secure a given page on my site: I want a login page for users to log into after which they have access to elevated features of the site (through spring security's authorization features). My question is: given what I described, what would be the strategy to create this login page which, after login, would grant the logged in user the appropriate authorities? The hack I thought of would be to create a simple JSP page who's only function is to redirect back to the previous page. Then I would use Spring Security to secure that JSP page. But it seems like there should be a better way of doing this... Thanks

• Type of object returned by an input from a web page

  - by controlfreak123

  I'm attempting to upload a file into a jsp and then use the file in some other code. My problem is that it comes into the servlet as an Object via the request.getAttribute() call so I don't know what to cast it to. I have this code so far to try and test what it is but I'm getting a NullPointerException. PrintWriter out = response.getWriter(); out.println(request.getAttribute("file1").getClass()); Is my understanding of whats going on flawed or am I just coding it up wrong?

• Problem reading from two separate InputStreams

  - by Emil H

  I'm building a Yammer client for Android in Scala and have encountered the following issue. When two AsyncTasks try to parse an XML response (not the same, each task has it's own InputStream) from the Yammer API the underlying stream throws a IOException with the message "null SSL pointer", as seen below: Uncaught handler: thread AsyncTask #1 exiting due to uncaught exception java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:200) at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:234) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:258) at java.util.concurrent.FutureTask.run(FutureTask.java:122) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:648) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:673) at java.lang.Thread.run(Thread.java:1060) Caused by: java.io.IOException: null SSL pointer at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.nativeread(Native Method) at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl.access$300(OpenSSLSocketImpl.java:55) at org.apache.harmony.xnet.provider.jsse.OpenSSLSocketImpl$SSLInputStream.read(OpenSSLSocketImpl.java:524) at org.apache.http.impl.io.AbstractSessionInputBuffer.fillBuffer(AbstractSessionInputBuffer.java:103) at org.apache.http.impl.io.AbstractSessionInputBuffer.read(AbstractSessionInputBuffer.java:134) at org.apache.http.impl.io.ContentLengthInputStream.read(ContentLengthInputStream.java:174) at org.apache.http.impl.io.ContentLengthInputStream.read(ContentLengthInputStream.java:188) at org.apache.http.conn.EofSensorInputStream.read(EofSensorInputStream.java:178) at org.apache.harmony.xml.ExpatParser.parseFragment(ExpatParser.java:504) at org.apache.harmony.xml.ExpatParser.parseDocument(ExpatParser.java:467) at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:329) at org.apache.harmony.xml.ExpatReader.parse(ExpatReader.java:286) at javax.xml.parsers.SAXParser.parse(SAXParser.java:361) at org.mediocre.util.XMLParser$.loadXML(XMLParser.scala:28) at org.mediocre.util.XMLParser$.loadXML(XMLParser.scala:12) ..... Searching for the error didn't give much clarity. Does this have something to do with the response from the server? Or is it something else? Complete code can be found at: http://github.com/archevel/YammerTime I get no error if I wait until the first repsponse is finished and then let the other complete. The request is made with the DefaultHttpClient, but this is supposedly thread safe. What am I missing? If anything needs to be clarified just ask :) Cheers, Emil H

• EJB3 Business Delegates

  - by mykola

  Is there any reason for making delegate when using EJB3? Because the only real benefit i see from delegate is that it allows to hide lookup and access details of EJB architecture. Well it also provides some decoupling but it's mostly unused, imho. With EJB3 we have injection so now i can just create a variable with @EJB annotation and use it as is. Do i still need delegates? Is this injection resource consuming? I mean if i use it in JSF's request managed beans may be it's still better to use delegates just to lessen these injection calls? Thank you!

• Problem with Google App Engine Appstats

  - by Taylor L

  I'm having an issue getting Appstats to work correctly. Using /appstats or /appstats/stats ends up in an infinite loop that keeps redirecting back to /appstats/stats. This results in a 404 error saying the page isn't redirecting properly. Any idea what the issue is? Here are the relevant lines in my appengine-web.xml. I've tried using both /appstats/stats and /appstats and they both have the same issue. <admin-console> <page name="Appstats" url="/appstats/stats" /> </admin-console> Below are the http headers showing the infinite redirect loop: http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcHiwT8jH7e01V9O5iFu3kpBhDd3k3oBwwxylv5u0DbJ- utvdpsgdb4Xim2WXwobkJmgTGGljvuh94_yVQ__- VPnBsTtUAhRjSyZ2Lv3G7oUHAxTsCWHJIMChGT3- XUyUNx8wxwvJisL_RTXH8Hc4TTLh_rVHm2k8gk8kgdbVZXexSV0K- a3coELTecWIBolt0qLd5L-5vALm382KsqbHorPXqoZMPTvR_06g_mR1cbmF2Ihnk6YhP7no58BNpESM9HvFyKNKXODo39hF4oaZCcW0Q9TBqUMgsrBqlcIh3- VvC7qvH0n_nAtrLTBbK_swnOFvCDcaf3whT9ty0CJ0VRNuNqIPOLHIeQAMgwXUNMr89P64EsgmuyONHR67glCQXEPOGXIaT1vcBJFwFoeNUqjdp824fHvoVhaL7Xlav- LTIFuM3f_ymHLmibk57PRuXUYEaAG HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.645553 X-AppEngine-Resource-Usage: ms=18965 cpu_ms=27884 api_cpu_ms=0 Set-Cookie: ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS; expires=Mon, 12-Apr-2010 19:41:49 GMT; path=/ Date: Sun, 11 Apr 2010 19:42:08 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, must-revalidate Content-Type: text/html Server: Google Frontend Content-Length: 0 ---------------------------------------------------------- http://mysite.appspot.com/appstats/stats GET /appstats/stats HTTP/1.1 Host: mysite.appspot.com User-Agent: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv: 1.9.2.3) Gecko/20100401 Firefox/3.6.3 (.NET CLR 3.5.30729) Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/ *;q=0.8 Accept-Language: en-us,en;q=0.5 Accept-Encoding: gzip,deflate Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 Keep-Alive: 115 Connection: keep-alive Cookie: USER_LOCALE=en_US; JSESSIONID=POTIUPPpEmjHZoaNDWOSTA; ACSID=AJKiYcF_YA7PB18b3T5OO7vEMo31f1hFhO8xKqFRiBUGrCr4YABAAyugZXcDfKMOM- r0FiK8xlOPfQWx3tOWIJ6ueOqK89X8M9YfHIs8WKUcSs6PwNZSKV0HKxvbqeWxfZI_cpo2YoS73s_RPlyEvjaYLOf6iXPpWeYyKTAbSqPOEBnVnTk3oso6ur66CIj3FnN8vsHfbanqY4sbaRsNj9pLjWZco0quYLOK1fd4wRZx_oAvk3jOlfAj7BZ7p9L1bO8oVCMpVn19cwT6zvO2-9RSjfiOPAacw7Cg0MT30r7Fr7SCj7VcSPAye4lc7tb9KL9ztZEk0xbEX-9vC6vHM_VfPJ54Kb_FycxE6lACsKTE4hj0bOa2-2quaOP0NSxfoH9ozLlQQCsGhpWBnlu__W06D0GqDqxcDUu2HocYqWuLi91aoa- aRTkqB_qo4aAa3OvHeKoFgwrS HTTP/1.1 302 Found Location: http://mysite.appspot.com/appstats/stats X-AppEngine-Estimated-CPM-US-Dollars: $0.002243 X-AppEngine-Resource-Usage: ms=64 cpu_ms=93 api_cpu_ms=0 Date: Sun, 11 Apr 2010 19:42:08 GMT Content-Type: text/html Server: Google Frontend Content-Length: 0

  i use proguard (support in mtj plugin) to obfuscate a project that has some third party jars but i gives me errors: Your input classes appear to be inconsistent. You may need to recompile them and try again. Alternatively, you may have to specify the options '-dontskipnonpubliclibraryclasses' and/or '-dontskipnonpubliclibraryclassmembers'. It seems that proguard use the classes in JavaSE. It only happens with projects that use third party jars :( Thank you in advanced!

• Why does my J2ME DateField not display the correct date?

  - by olly

  I am storing values and date values in a record store. I have my date field set up like this: StartDate = new DateField("Start Date ", DateField.DATE); cal1 = Calendar.getInstance(); cal1.set(Calendar.YEAR, 2009); cal1.set(Calendar.MONTH, 0); cal1.set(Calendar.DAY_OF_MONTH, 1); StartDate.setDate(cal1.getTime()); and I save the date as a string as follows: strStartDate = cal1.get(cal1.DAY_OF_MONTH) + "/" + (cal1.get(cal1.MONTH) + 1) + "/" + cal1.get(cal1.YEAR); String detailsToAdd = strStartDate (I have shortened the code.) Now, I want to be able to edit the date at a future stage. However, I need the code to be able to do this. So far I have: EStartDate = new DateField("Start Date ", DateField.DATE); I had to change the name of the DateField box as this was conflicting with other things. I basically need to be able to show the selected record's date attribute. I currently have the other information displayed. I just need to be able to show the correct date. When I run the program the date field says <date>. Any help will be nice

• Data in J2ME RecordStore does not persist across sessions

  - by Botond Balázs

  I'm building a mobile app with J2ME, and I've found that the data I write into a RecordStore can be accessed while the program is still running but it is lost after quitting and restarting it. No exception is thrown, the data is simply lost. UPDATE: Thanks everyone for your suggestions. I'm using NetBeans on Windows 7. I'm not sure if it is using the WTK version I have previously installed or another one it has installed somewhere else. I've checked my WTK folder for the files Pavel wrote about, but couldn't find them. Now I'm testing the features requiring persistence on my phone and everything else in the emulator, but it would of course be much better to be able to test everything in the emulator. private RecordStore recordStore = null; public MyMIDlet() { readStuff(); // output: nothing found in recordStore :( saveStuff(); readStuff(); // output: stuff } private void readStuff() { try { recordStore = RecordStore.openRecordStore(REC_STORE, true); int n = recordStore.getNumRecords(); String stuff; if (n == 0) { stuff = "nothing found in recordStore :("; } else { stuff = new String(recordStore.getRecord(1)); } System.out.println(stuff); } catch (Exception e) { System.out.println("Exception occured in readStuff: " + e.getMessage()); } finally { if (recordStore != null) { try { recordStore.closeRecordStore(); } catch (Exception e) { // ignore } } } } private void saveStuff() { try { recordStore = RecordStore.openRecordStore(REC_STORE, true); int n = recordStore.getNumRecords(); byte[] stuff = "stuff".getBytes(); recordStore.addRecord(stuff, 0, stuff.length); } catch (Exception e) { System.out.println("Exception occured in saveStuff: " + e.getMessage()); } finally { if (recordStore != null) { try { recordStore.closeRecordStore(); } catch (Exception e) { // ignore } } } }

• How do I make "simple" throughput servlet-filter?

  - by Tommy

  I'm looking to create a filter that can give me two things: number of request pr minute, and average responsetime pr minute. I already got the individual readings, I'm just not sure how to add them up. My filter captures every request, and it records the time each request takes: public void doFilter(ServletRequest request, ...() { long start = System.currentTimeMillis(); chain.doFilter(request, response); long stop = System.currentTimeMillis(); String time = Util.getTimeDifferenceInSec(start, stop); } This information will be used to create some pretty Google Chart charts. I don't want to store the data in any database. Just a way to get current numbers out when requested As this is a high volume application; low overhead is essential. I'm assuming my applicationserver doesn't provide this information.

• javax.naming.NameAlreadyBoundException: in glassfish server v2

  - by Nila

  Hi! I'm implementing stateless session bean ejb3 in glassfish server using netbeans. First time, it is working properly. Later, I'm getting the exception as follows: LDR5012: Jndi name conflict found in [SampleEjb3]. Jndi name [Lulu.HellostatelessRemote] for bean [HellostatelessBean] is already in use. LDR5013: Naming exception while creating EJB container: javax.naming.NameAlreadyBoundException: Use rebind to override at com.sun.enterprise.naming.TransientContext.doBindOrRebind(TransientContext.java:292) at com.sun.enterprise.naming.TransientContext.bind(TransientContext.java:232) at com.sun.enterprise.naming.SerialContextProviderImpl.bind(SerialContextProviderImpl.java:111) at com.sun.enterprise.naming.LocalSerialContextProviderImpl.bind(LocalSerialContextProviderImpl.java:90) at com.sun.enterprise.naming.SerialContext.bind(SerialContext.java:461) at com.sun.enterprise.naming.SerialContext.bind(SerialContext.java:476) at javax.naming.InitialContext.bind(InitialContext.java:404) at com.sun.enterprise.naming.NamingManagerImpl.publishObject(NamingManagerImpl.java:237) at com.sun.enterprise.naming.NamingManagerImpl.publishObject(NamingManagerImpl.java:190) at com.sun.ejb.containers.BaseContainer.initializeHome(BaseContainer.java:1015) at com.sun.ejb.containers.StatelessSessionContainer.initializeHome(StatelessSessionContainer.java:232) at com.sun.ejb.containers.ContainerFactoryImpl.createContainer(ContainerFactoryImpl.java:654) at com.sun.enterprise.server.AbstractLoader.loadEjbs(AbstractLoader.java:536) at com.sun.enterprise.server.ApplicationLoader.doLoad(ApplicationLoader.java:188) at com.sun.enterprise.server.TomcatApplicationLoader.doLoad(TomcatApplicationLoader.java:126) at com.sun.enterprise.server.AbstractLoader.load(AbstractLoader.java:244) at com.sun.enterprise.server.AbstractManager.load(AbstractManager.java:225) at com.sun.enterprise.server.ApplicationLifecycle.onStartup(ApplicationLifecycle.java:217) at com.sun.enterprise.server.ApplicationServer.onStartup(ApplicationServer.java:442) at com.sun.enterprise.server.ondemand.OnDemandServer.onStartup(OnDemandServer.java:120) at com.sun.enterprise.server.PEMain.run(PEMain.java:411) at com.sun.enterprise.server.PEMain.main(PEMain.java:338) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.sun.enterprise.server.PELaunch.main(PELaunch.java:412) Then, I'll remove the ejb module from the glassfish server and I'll restart the server. It will work then. So, how to overcome this problem..

• How to zoom in google map (J2ME)

  - by Nivek

  Hi all, I am trying to develop a J2ME application that could retrieve the google map by passing in the GPS coordinates. From http://wiki.forum.nokia.com/index.php/Google_Maps_API_in_Java_ME, it provides the Utility method for map scrolling. Basically it states that i need to include MicroFloat library in my project. Here's what i did (Not sure if i am doing it right) Create a project, build the code. Add the jar file into my current project lib. but i am still getting error from codes. Example double LToY(double y) { return Math.round( offset - radius * Double.longBitsToDouble(MicroDouble.log( Double.doubleToLongBits( (1 + Math.sin(Math.toRadians(y))) / (1 - Math.sin(Math.toRadians(y))) ) )) / 2); } Am i missing any import statment??? Btw i am using netbeans 6.5. Thanks for any guidance... Kevin

• Logging exceptions during bean injection

  - by Marc W

  I think this is a pretty basic question, but after Googling around I can't seem to find the answer. What I need is a way to log some custom output with log4j during Spring bean construction. I have a factory class called ResponderFactory (being used as an instance factory in Spring) with a factory method that can throw 2 different types of exception. public CollectorResponder collectorResponder(String inputQueueName) throws ConfigurationException, BrokerConnectionException {} Now, normally I could wrap a call to this method in a try-catch block with 2 catch clauses to handle the logging situations for each of the exceptions. However, if I'm using Spring to inject this CollectorResponder, created with the factory, into another class I don't see how this is possible. <bean id="responderFactory" class="com.package.ResponderFactory"> <constructor-arg index="0" ref="basicDispatcher" /> <constructor-arg index="1" value="http://localhost:9000" /> </bean> <bean id="collectorResponder" class="com.package.CollectorResponder" factory-bean="responderFactory" factory-method="collectorResponder"> <constructor-arg value="collector.in" /> </bean> <bean id="collectorConsumer" class="com.package.CollectorConsumer"> <constructor-arg ref="collectorResponder" /> </bean> Again, I want to catch these exceptions when the collectorResponder bean is instantiated. Right now I'm dealing with this is CollectorConsumer when I instantiate using new CollectorResponder(...). Is there any way I can do this?
