Avoid need for multiple javax.servlet ------------------------------------- Key: JBIDE-19605 URL: https://issues.jboss.org/browse/JBIDE-19605 Project: Tools (JBoss Tools) Issue Type: Enhancement Components: target-platform, webservices Affects Versions: 4.3.0.Alpha2 Reporter: Mickael Istria Assignee: Brian Fitzpatrick Fix For: LATER We currently use 2 different version of javax.servlet bundle. We'd rather decide on sticking to 1. {code} On 04/15/2015 11:56 PM, Nick Boldt wrote: > Just wondering if anyone knows WHY we include javax.servlet 3.0.0 and > 3.1.0 in JBDS. > More importantly... SHOULD we be including both? Or can we just include > 3.1.0 and drop 3.0.0? I have JBDS installed from installer, which basically ran a p2 director. And I get jetty 3.0.0 and jetty 3.1.0. Than means that while resolving what to installed, p2 has to keep both versions of javax.servlet. That's definitely a sign that our dependency chain currently need both (or p2 wouldn't have installed both). So I've tried the ultimate test: $ cd jbdevstudio-9.0.0.Alpha2/studio $ rm plugins/javax.servlet_3.0.0* $ ./jbdevstudio And saw !ENTRY org.jboss.tools.ws.ui 4 0 2015-04-16 10:35:49.110 !MESSAGE FrameworkEvent ERROR !STACK 0 org.osgi.framework.BundleException: Could not resolve module: org.jboss.tools.ws.ui [967] Unresolved requirement: Import-Package: javax.servlet; version="[2.4.0,3.0.0)" at org.eclipse.osgi.container.Module.start(Module.java:434) at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.incStartLevel(ModuleContainer.java:1582) at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.incStartLevel(ModuleContainer.java:1561) at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.doContainerStartLevel(ModuleContainer.java:1533) at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.dispatchEvent(ModuleContainer.java:1476) at org.eclipse.osgi.container.ModuleContainer$ContainerStartLevel.dispatchEvent(ModuleContainer.java:1) at org.eclipse.osgi.framework.eventmgr.EventManager.dispatchEvent(EventManager.java:230) at org.eclipse.osgi.framework.eventmgr.EventManager$EventThread.run(EventManager.java:340) Fun thing is that the javax.servlet_3.0.0 actually exports packages in version 2.6.0, whereas javax.servlet_3.1.0 exports them in version 3.1.0. {code}
