Re: Initializing Web Service (Server) before first request received
I'm not sure I ever fully understood this, even after reading the docs on the service lifecycle a few times. What I found was that the methods did not fire the same way during hot deployment as they do on startup so don't get fooled by that. The best I came up with was use application scope, restart tomcat whenever I needed to apply a change, and the init method was the best place to put any one time setup code. hth charles On Feb 10, 2010, at 5:23 AM, Doughty, Michael wrote: > In your services.xml file, add 'scope=" application"' to the "service" > element, as follows: > > > > The service will then be deployable in application mode. > > Now a question to Deepal... will this actually load the implementation class > immediately on deployment and thus cause all static initialization in the > class to take place? > > I know that application mode will cause Axis2 to treat the implementation > class as a singleton and reuse the same instance for each service call, but I > was still under the impression that it would require that first service call > to be made still.

Re: archive lib directory and 3rd party libraries (axis2/tomcat 6)
Thanks for your help with this Andreas I put a bunch of debug statements in various places and found the WebappClassLoader was being used consistently throughout. I still don't understand what was happening in this SQLException case, but I did end up finding my problem(s) stem from the use of a singleton class in the legacy code I am using that is effectively thwarting what I want to do anyway.

Re: archive lib directory and 3rd party libraries (axis2/tomcat 6)
Hi Andreas I tried setting the TCCL to both the class loader of the service context as well as the service group context before starting the threaD, but still no change. I guess this leaves me with a couple of questions. 1. Do subsequent threads spawned inherit the same TCCL? I'm pretty sure other threads are spawned by this thread which then go on to do the work. 2. How can I tell what class loader is being used? Just log whatever this.getClassLoader() returns anywhere I care? 3. Is init perhaps the wrong place to be firing this off? I originally tried in the startUp method but iirc member variables initialized here were not retained when the service methods were invoked. thanks, charles On Jan 25, 2010, at 3:57 PM, Andreas Veithen wrote: > Charles, > > That might actually explain the issue.

Re: archive lib directory and 3rd party libraries (axis2/tomcat 6)
It's just a thread spawned from the lifecycle init method using new Thread()… The general idea is we have an existing code base that used to be launched as commandline apps. I am now launching them in a thread from my web services, and "web enabling" them. Admittedly there were not designed or built to be used this way, but I don't think there should be anything stopping me from doing this. The Corba initialization occurs in the client.corba.* packages, but they are just calling org.omg.CORBA.ORB.init which is doing the class loading and thats from rt.jar in the java distro afaik. The ORB loaded is a configurable option which is why it uses the class loader (IE not in my control). I got past this one by putting the corba.jar into WEB-INF/lib. The SQLException I describe below occurs when a call is made to DriveManager.getConnection(..) and works fine loading a single service/.aar charles On Jan 25, 2010, at 3:12 PM, Andreas Veithen wrote: > Charles, > > According to the stack trace you posted, the error occurs inside a > thread that is neither managed by the servlet container, nor by Axis2: > > 13:38:58 DEBUG- Stack trace: org.omg.CORBA.INITIALIZE: can't > instantiate default ORB implementation org.jacorb.orb.ORB vmcid: 0x0 > minor code: 0 completed: No >at org.omg.CORBA.ORB.create_impl(ORB.java:297) >at org.omg.CORBA.ORB.init(ORB.java:336) >at client.corba.BaseCORBAApp.initCORBA(BaseCORBAApp.java:134) >at > client.corba.BaseCORBAService.startService(BaseCORBAService.java:100) >at > client.project.dcol.publish.corba.WebServiceDataCollectionService.webInit(WebServiceDataCollectionService.java:170) >at > client.project.dcol.GDPI.ServiceBase$ServiceThread.run(ServiceBase.java:318) >at java.lang.Thread.run(Thread.java:619) > > How and where is this thread created? > > Andreas > > On Mon, Jan 25, 2010 at 20:23, Charles Galpin wrote: >> Thanks Andreas >> >> I added this to both services being loaded, rebuilt and ran, but no change. >> >> The composite class loader was one of the options described in Amil's blog >> and as I understand it, it is supposed to use both the TCCL and the service >> class loader.

Re: archive lib directory and 3rd party libraries (axis2/tomcat 6)
Thanks Andreas I added this to both services being loaded, rebuilt and ran, but no change. The composite class loader was one of the options described in Amil's blog and as I understand it, it is supposed to use both the TCCL and the service class loader. But I guess I still don't understand the class loading because this jar is in all the places the class loaders should be looking so I don't see how it matters which one it uses. I also tried the "EnableChildFirstClassLoading" parameter as well but no help.

Re: archive lib directory and 3rd party libraries (axis2/tomcat 6)
Hi All I am still running into problems with this. I previously moved all the jars I needed into the WEB-INF/lib directory and was able to continue working. But as I add more services (more .aar files) I am now running into strange unpredictable differences that I do not understand. For example, I have two services packaged in their own .aar files and if deployed independently they run just fine. Simply deploying both together causes the second one loaded to have mysterious problems like a java.sql.SQLException "no suitable driver found for jdbc:sqlserver://.." when the sql3jdbc jar file is in both the .aar and WEB-INF/lib directory and (and as I said works fine standalone). Does anyone have any advice on how to get my services to run together happily? Assume I am not concerned with isolating each service from each other in terms of security. I read on Amila's blog that some class loading settings can be modified but it's not clear exactly what ramifications it will have or if it will even help my problems. I am not sure if this is causing my problems, but due to wanting to be able to override the properties file in the .aar file when deployed in different environments, in the service lifecycle init method I attempt to find the properties file in the axis classpath before trying the .arr, using first axisService.getClass().getClassLoader(0.gerResourceAsStream(propsFilename); and if not found then using this.getClass().getClassLoader(0.gerResourceAsStream(propsFilename); Could this be messing up the class loading sequence, and if yes, how can I achieve the same effect without using the axis class loader first? thanks, charles On Dec 1, 2009, at 2:29 PM, Charles Galpin wrote: > Hi Sameera > > Ok, this is starting to make a little more sense.

archive lib directory and 3rd party libraries (axis2/tomcat 6)
Some jar files in my .aar lib directory do not appear to be loaded or recognized (I get ClassNotFound exceptions). If I put the jars in axis2/WEB-INF/lib directory they are loaded fine. Other jars are loaded fine so I don't think it's me putting them in the wrong place in the .aar. Any suggestions on how to debug this? TIA, charles

No, never used Axis1, sorry.

Re: How to read parameter in WebService
You need to get a reference to the AxisService and then you can do
axisService.getParameterValue("myname");
AxisService is provided in some lifecycle methods, in others like the init
method you need
axisService = serviceContext.getAxisService();

Re: [Axis2] Setting nillable = false in WSDL
There are open bugs on this and related issues with the wsdl generation. Please vote for them if you care about these kinds of issues as this should help them get priority. http://issues.apache.org/jira/browse/AXIS2 thanks, charles On Nov 13, 2009, at 7:50 AM, Didav Didav wrote: Hi All, I am using Axis2 1.3 and jdk 1.5 and tomcat 6 The WSDL file generated by Axis sets the element "nillable=true", but i want to set "nillable=false"...

I try with the annotation @XmlElement(nillable = false, required=true) but it doesn't work :( Thanks a lot, David PC, téléphones portables, souris hi-tech. à gagner grâce à Hotmail ! C'est ici !
Re: tracking down reason for AxisFault fromIllegalArgumentException
Hi Deepal I have submitted a bug report for this, http://issues.apache.org/jira/browse/AXIS2-4541 Also, I had thought that I had this working with another service, but it turns out it doesn't work either. I got different errors for that one - it seemed to be getting a large number of spaces for the input variables. But take a look at this one and I can submit a test case for the other if needed.

Thanks, Deepal Hi All First time poster using axis2-1.5 I have a POJO based service which works fine other than axis has a bug that generates minOccurs="0" in the auto generated WSDL for all method parameters, even though they are required. So I am trying to work around this using a method I have used on other services - serving a static WSDL. I took the auto-generated WSDL, made a few minor changes to the method parameters to be minOccurs="1" , copy it to the META-INF directory as part of my build, and in services.xml added the parameter useOriginalwsdl=true. Now I get this obscure fault when invoking the method that I can't figure out. How do I determine why I'm getting an IllegalArgumentException with no other changes? I have full DEBUG level logging enabled but it gives no useful info (to me anyway) :) thanks, charles
Re: tracking down reason for AxisFault from IllegalArgumentException
Hi Deepal This is pretty entrenched in our code base including the build. I'll make a paired down version that will hopefully display the problem and create a report, thanks. But as I said it works on another service so not sure what the difference is. To be clear we are talking about the error and not the minOccurs fix right? I looked and it didn't looked like the existing reports for the minOccurs issue were ever addressed, and this is the core problem. But I'd be happy with a work around or fix for this either way :) thanks, charles - Original Message - From: "Deepal jayasinghe" To: axis-user@ws.apache.org Sent: Friday, October 30, 2009 8:40:12 PM GMT -05:00 US/Canada Eastern Subject: Re: tracking down reason for AxisFault fromIllegalArgumentException hi Charles, I remember I fixed this issue sometimes ago, but now it has appear again in 1.5 and 1.5.1 release.
