Solution and implementation is perfect in my opinion. If no one has any objections I would suggest to have it incorporated with 4.4 release.

[JBoss Web Development] - Annotation processing in war files too aggressive?

by jaikiran pai

jaikiran pai [http://community.jboss.org/people/jaikiran] created the discussion "Annotation processing in war files too aggressive?" To view the discussion, visit: http://community.jboss.org/message/547701#547701 -------------------------------------------------------------- I have got a simple war file which contains an EJB3 bean (testing against AS trunk). The bean looks like this: @Stateless public class SimpleSLSB extends SimpleBase { ... The SimpleBase class (from which this bean extends) looks like: public class SimpleBase { @Resource private EJBContext ejbContext; So this base class is just a POJO with @Resource injection for EJBContext. During deployment of this .war on AS trunk, the web application deployer incorrectly starts processing this SimpleBase class and throws this exception: 14:32:31,422 ERROR [StandardContext] Context [/myapp] startup failed due to previous errors: java.lang.RuntimeException: mapped-name is required for org.myapp.ejb3.impl.SimpleBase/ejbContext of deployment myapp.war at org.jboss.web.tomcat.service.injection.WebResourceHandler.loadXmlResourceEnvRefs(WebResourceHandler.java:287) [:6.0.0-SNAPSHOT] at org.jboss.web.tomcat.service.injection.WebResourceHandler.loadXml(WebResourceHandler.java:325) [:6.0.0-SNAPSHOT] at org.jboss.web.tomcat.service.TomcatInjectionContainer.processMetadata(TomcatInjectionContainer.java:593) [:6.0.0-SNAPSHOT] at org.jboss.web.tomcat.service.WebCtxLoader.start(WebCtxLoader.java:157) [:6.0.0-SNAPSHOT] at org.apache.catalina.core.StandardContext.start(StandardContext.java:3737) [:] at org.jboss.web.tomcat.service.deployers.TomcatDeployment.performDeployInternal(TomcatDeployment.java:309) [:6.0.0-SNAPSHOT] at org.jboss.web.tomcat.service.deployers.TomcatDeployment.performDeploy(TomcatDeployment.java:144) [:6.0.0-SNAPSHOT] at org.jboss.web.deployers.AbstractWarDeployment.start(AbstractWarDeployment.java:461) [:6.0.0-SNAPSHOT] at org.jboss.web.deployers.WebModule.startModule(WebModule.java:116) [:6.0.0-SNAPSHOT] at org.jboss.web.deployers.WebModule.start(WebModule.java:95) [:6.0.0-SNAPSHOT] The real issue here is that the WarAnnotationDeployer picks up this SimpleBase class for annotation processing and creates metadata for @Resource and adds it to the WebAppMetaData (resourceEnvRefGroups). Shouldn't the annotation deployer just pick up servlets (and maybe some additional classes for Servlet 3.0 spec?) for annotation processing? IMO, the SimpleBase class should have been completely skipped from annotation processing in the WarAnnotationDeployer. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/547701#547701] Start a new discussion in JBoss Web Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

All of testcase could pass. If you have time, please have a look at it. The key is we have to generate dbid, parent id, then we could save the execution. And the code for generating dbid is only exists in the save() method. setParent() mehod is only exists in the addExecution() method. So this time, I execution setParent() by hand before save(). I think this could be solve this problem. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/547670#547670] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[Javassist Development] - Problem with CodeIterator.newOffset()

by Alasdair Mackintosh

Alasdair Mackintosh [http://community.jboss.org/people/alasdair] created the discussion "Problem with CodeIterator.newOffset()" To view the discussion, visit: http://community.jboss.org/message/547652#547652 -------------------------------------------------------------- I've been having some problems with Javassist which I think I've finally narrowed down to the way that "goto" offsets are updated when you insert new bytecode. It looks as though newOffset is not correctly handling the case when you insert new opcodes at a location which already contains a "goto" opcode. private static int newOffset(int i, int offset, int where, int gapLength, boolean exclusive) { int target = i + offset; if (i < where) { if (where < target || (exclusive && where == target)) offset += gapLength; } else if (i == where) { if (target < where && exclusive) offset -= gapLength; else if (where < target && !exclusive) offset += gapLength; } else if (target < where || (!exclusive && where == target)) offset -= gapLength; return offset; } And I think the middle clause should look like this: else if (i == where) { if (target < where) offset -= gapLength; } If you insert new bytecode at a location containing a goto (so that the goto opcode is about to be moved forward by n bytes) then you need to modify the offset if it's negative, but keep it the same if it's already positive. I've made this change and re-run the tests, which all pass, but I wanted to check to see if this fix looks reasonable. I don't have a simple test case that shows the problem. I found this when I tried to run my testing framework ThreadWeaver ( http://code.google.com/p/thread-weaver/ http://code.google.com/p/thread-weaver/) with the latest version of Javassist. The problem can be demonstrated by building ThreadWeaver and running the unit tests. If you want a simpler test case let me know. I think THreadWeaver triggered this because it uses Javassist to insert lots of small code snippets into the instrumented bytecode.
