I'm using Websphere portal 6.0 and I'm wondering if there's a way in which I can tell the server which page to render from the doView method. I know I can do it from the processAction method but unfortunately the semantics of the problem don't allow it. Thank you for your help ...
Hello. How can one set character encoding on external JavaScript files using only Websphere (5.1)? I don't have Apache in front of it so I can't set it using "AddCharset UTF-8 .js". Or maybe there is some other way to force it on a web container via web.xml or similar magic? ...
I am using IBM Websphere Application Server v6 and Java 1.4 and am trying to write large CSV files to the ServletOutputStream for a user to download. Files are ranging from a 50-750MB at the moment. The smaller files aren't causing too much of a problem but with the larger files it appears that it is being written into the heap which is...
I have a war file (actually not my own, it's Apache ODE 1.2) that fails to deploy into WAS 6.1 because of a classloader issue - and a specific incompatibility with wsdl4j. If I manually edit the classloader for ODE and create a shared-library for wsdl4j1.6.1 it's all fine. However, the client has come back stating this is not acceptable...
I work on a task that involves moving/traversing from one application to another. The applications are in separate JVMs. While traversing to the other application, I keep track of the session ID. However, as I traverse back and forth, a new session gets created. Is there any way for me to get back the same session, using the sessionId...
We're running a fairly complex app as a portlet on Websphere Portal Server 5.1 on AIX using IBM JDK 1.4.2. On our production system I can see a strange behaviour in the verbose GC logs. After a period of normal behaviour the system can start rapidly allocating larger and larger blocks. The system starts to spend > 1000 ms to complete eac...

We have a Websphere JEE application that requires parallelization, for which we're looking to use CommonJ work components. Each 'thread' would require its own view onto data coming from a database. Most of this would be pre-fetched, but it would still need to go to the database to get some. We anticipate that the duration of the overa...
I have a J2EE application running on an IBM Websphere Application Server on a Windows Operating System. Occasionally I see an OutOfMemoryError Exception with the following information in the javacore file. 1TISIGINFO Dump Event "systhrow" (00040000) Detail "java/lang/OutOfMemoryError":"Failed to create a thread: retVal -1073741830...
We are in the process of doing a POC on AJAX push technology. Some of the things we are looking at are Ice Faces Push Technology, Richfaces a4j:push and WebSphere Application Server Feature Pack for Web 2.0. We find an issue with WebSphere Application Server Feature Pack for Web 2.0 in that going down this road we become a slave to th...
First, just a bit of background: One of our customers is experiencing CPU usage spikes for WebSphere instances running one of our web apps (other instances with other apps are fine). They have a test environment and a live environment (both iSeries) which both experience the problem - with a single app per instance setup. We have deploy...
I have a JEE application that runs on WAS 6. It needs to have the class loader order setting to "Classes loaded with application class loader first", and the WAR class loader policy option set to "Single class loader for application". Is it possible to specify these options inside the EAR file, whether in the ibm-web-bnd.xmi file or so...

I have a .NET WCF service which exposes an object that uses polymorphism. Apparantly, Websphere Integration Developer is unable to handle this properly (I am not the Websphere developer), except by adding all fields of all possible polymorphisms and using a enum or such to say that it is an object of such and such type. I can't possi...
Websphere Integration Developer seems to have a bug with nullable types. To get around it, you need to ensure that all nullable types (including reference types) have a value set. I haven't digged deep in this yet, the problem might be that a null element isn't included at all, and perhaps thus causes it to break, but it'll be easier i...
Does anyone have any performance tips or other help for local development with websphere and rad. I am using one web app of moderate size (1000? classes) and it is impossible to handle the app locally on a windows box. The websphere 6.1 configuration uses the default configs. RAD7 is configured to handle a max heap of 1024mb. I thoug...
Does anyone know if it is possible to export existing configuration of websphere application server 6.1 and import it to other instance of WAS ? ...
We're developing a web application with Rational Application Developer 7.5 (based on Eclipse 3.4) for WebSphere Application Server 6.1 . When examining stacktraces on a staging server, the line numbers always point to the beginning of the methods, never to the actual line. In the local development environment (each developer has his loca...
Hi, What is the differece between a dead letter Queue and a back out queue? In WebSpehre MQ terms and in terms of Application Servers. All J2EE app servers have a MQ Provider do they also have a construct of a Dead Letter Queue or is that something specific to WebSphere MQ? My understanding of a back out queue is as follow: If MQ is...
