[Design of JBoss Portal] - Accessing session attributes in a portlet

by segal96

I have a servlet filter intercepting all http reqs to my portal and setting session attributes (strings) that I'd like to access in portlets. Is this possible? If so, can someone tell me what I'm doing wrong? ######### In the servlet: ######### HttpSession session = httpRequest.getSession(true); session.setAttribute("attr1","somestring"); ######### In the portlet: ######### String attribute = (String)readRequest.getPortletSession().getAttribute("attr1", PortletSession.APPLICATION_SCOPE); // Always returns null for some reason??? System.out.println(attribute); Cheers, -Steve View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199612#4199612 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4199612

[Design the new POJO MicroContainer] - Using ClassInfo in JBoss AOP

by kabir.khan＠jboss.com

We would like to start using ClassInfo in JBoss AOP, since that will get rid of the duplicated code we have in our pointcut matchers. Currently we have code doing the same thing for javassist (during weaving) and for java.lang.reflect (to populate the advisors of woven classes at runtime). For our use the current implementation of JavassistTypeInfoFactoryImpl has a few problems: 1) From what I can see, it does not allow the specification of a javassist ClassPool to use, instead it falls back on ClassPool.getDefault(), which just gives you the stuff on the bootstrap classpath, and so will not work in AS for application classes. It should be possible to pass in the ClassPool to use, or if working out the ClassPool from the classloader, to pass in some kind of ClassPool factory so that it uses the same underlying ClassPool as AOP does. 2) We would want to use the javassist version of ClassInfo during weaving, i.e. before the classes are loaded. However, the WeakClassCache used by JavassistTypeInfoFactoryImpl seems to need to load the class: | Thread [main] (Suspended (breakpoint at line 126 in JavassistTypeInfoFactoryImpl)) | JavassistTypeInfoFactoryImpl.instantiate(Class) line: 126 | JavassistTypeInfoFactoryImpl(WeakClassCache).get(Class) line: 67 | JavassistTypeInfoFactoryImpl.getTypeInfo(Class<?>) line: 280 | JavassistTypeInfoFactoryImpl.getTypeInfo(String, ClassLoader) line: 312 | JavassistTypeInfoFactory.getTypeInfo(String, ClassLoader) line: 54 | JavassistArrayUnitTestCase(AbstractClassInfoTest).testBasics(Class<?>, TypeInfo) line: 72 | JavassistArrayUnitTestCase(ClassInfoArrayTest).testArray(Object) line: 139 | JavassistArrayUnitTestCase(ClassInfoArrayTest).testSimpleArray() line: 46 | So that is not good for us. We need a javassist version of ClassInfo to use during weaving that does not load the class as part of its instantiation, once woven the class can be put into the WeakClassCache.

[Design of EJB 3.0] - Re: EJBTHREE-1607 Update EJB3.0 Tutorials

by jaikiran

Most of the tutorials are now ready and even the guide for these working tutorials has been made available. The wiki has been updated with the steps to build the tutorials/guide https://www.jboss.org/community/docs/DOC-13215. There are around 10 more tutorials remaining which i plan to take up this week. We can even discuss about making the guide available online during this week. "ALRubinger" wrote : I think you should have permissions on my machine if you'd like to make a new Job there.

[Design of JBoss Web Services] - Webservice and C lang

by RajaRamana

Hi, I am looking for help to provide a service between J2EE and C lang. 1. I have created the following Web Service in J2EE /* * @WebService indicates that this is webservice interface and the name * indicates the webservice name. */ @WebService(name = "Hello") /* * @SOAPBinding indicates binding information of soap messages. Here we have * document-literal style of webservice and the parameter style is wrapped. */ @SOAPBinding ( style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.WRAPPED ) public class Hello { /** * This method takes a input parameter and appends "Hello" to it and * returns the same. * * @param name * @return */ @WebMethod public String greet( @WebParam(name = "name") String name ) { return "Hello " + name; } } 2. Configured in web.xml <servlet-name>Hello</servlet-name> <servlet-class>com.carrefour.cmt.central.webservice.Hello</servlet-class> <load-on-startup>1</load-on-startup> <servlet-mapping> <servlet-name>Hello</servlet-name> <url-pattern>/Hello</url-pattern> </servlet-mapping> 3. Started Jboss421. After that it created a wsdl file in DATA folder. 4 Now i want to write a Client to consume the service in 'C' LANG. Please Assist me.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Maximum path length easly exceeded

by timfox

Also, bear in mind that base 64 encoding will increase the length of the string, so the actual address might be significantly less than 255 chars.

Actually on my Linux lap top, it fails at 255 characters. Here's the test program: | public void testCreateDirs() throws Exception | { | String dir = "/tmp/jbm-unit-test/page/"; | | for (int i = 0; i < 1000; i++) | { | dir += "X"; | | File f = new File(dir); | | boolean ok = f.mkdirs(); | | if (!ok) | { | throw new IOException("failed at " + i); | } | } | } | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4199494#4199494 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4199494

[Design of Messaging on JBoss (Messaging/JBoss)] - Maximum path length easly exceeded

by timfox

It's easy to get the system to fail by specifying an address that's long - the paging system attempts to create directory even though it's not paging. (Why create the directory if not paging?) Most OSes have limits on the maximum path length e.g. 4095 in Linux, so clearly using the address name is not going to work. A better solution needs to be worked out - e..g store the real address in a file in the paging directory.
