Running XWiki Locally using Eclipse
by Bikash Agarwalla 13 Aug '05

13 Aug '05

Hello, I am working on new xml-rpc apis for p2pxwiki, and am using Eclipse as just my editor (I am not doing any development related to eclipse). I imported the xwiki project in eclipse and used resin to run xwiki locally. I got some errors (most of them "seems" benign, but I wanted to point out anyway incase these will lead to more problems later) a) Eclipse complained about a missing commons-lang-2.0.jar in the lib directory. I checked the lib directory, it has "commons-lang-2.1.jar" instead. I am not sure why Eclipse is not using the new library. As a fix I downloaded the 2.0 version of commons-lang and put it in the lib directory. It solved this problem. b) After running xwiki locally, "http://127.0.0.1:8080/xwiki/bin/view/Main/WebHome" pointed to a xwiki document. However, I got few errors on the resin console as follows (the transcript follows below) Let me know how I can fix these problems. I am using FC4. Thanks a lot, -Bikash -----------------------------o<---------Error Transcript -------------- o<------------- (i) log4j:ERROR setFile(null,true) call failed. java.io.FileNotFoundException: xwiki.log (Permission denied) at java.io.FileOutputStream.openAppend(Native Method) at java.io.FileOutputStream.<init>(FileOutputStream.java:177) at java.io.FileOutputStream.<init>(FileOutputStream.java:102) at org.apache.log4j.FileAppender.setFile(FileAppender.java:272) at org.apache.log4j.RollingFileAppender.setFile(RollingFileAppender.java:156) at org.apache.log4j.FileAppender.activateOptions(FileAppender.java:151) at org.apache.log4j.config.PropertySetter.activate(PropertySetter.java:247) at org.apache.log4j.config.PropertySetter.setProperties(PropertySetter.java:123) at org.apache.log4j.config.PropertySetter.setProperties(PropertySetter.java:87) at org.apache.log4j.PropertyConfigurator.parseAppender(PropertyConfigurator.java:645) at org.apache.log4j.PropertyConfigurator.parseCategory(PropertyConfigurator.java:603) at org.apache.log4j.PropertyConfigurator.configureRootCategory(PropertyConfigurator.java:500) at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:406) at org.apache.log4j.PropertyConfigurator.doConfigure(PropertyConfigurator.java:432) at org.apache.log4j.helpers.OptionConverter.selectAndConfigure(OptionConverter.java:460) at org.apache.log4j.LogManager.<clinit>(LogManager.java:113) at org.apache.log4j.Logger.getLogger(Logger.java:85) at org.apache.commons.logging.impl.Log4JLogger.getLogger(Log4JLogger.java:229) at org.apache.commons.logging.impl.Log4JLogger.<init>(Log4JLogger.java:65) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at org.apache.commons.logging.impl.LogFactoryImpl.newInstance(LogFactoryImpl.java:529) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:235) at org.apache.commons.logging.impl.LogFactoryImpl.getInstance(LogFactoryImpl.java:209) at org.apache.commons.logging.LogFactory.getLog(LogFactory.java:351) at org.apache.struts.action.ActionServlet.<clinit>(ActionServlet.java:228) at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:39) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:27) at java.lang.reflect.Constructor.newInstance(Constructor.java:494) at java.lang.Class.newInstance0(Class.java:350) at java.lang.Class.newInstance(Class.java:303) at com.caucho.server.dispatch.ServletConfigImpl.createServlet(ServletConfigImpl.java:584) at com.caucho.server.dispatch.ServletManager.init(ServletManager.java:152) at com.caucho.server.webapp.Application.start(Application.java:1546) at com.caucho.server.deploy.DeployController.startImpl(DeployController.java:563) at com.caucho.server.deploy.StartAutoRedeployAutoStrategy.startOnInit(StartAutoRedeployAutoStrategy.java:72) at com.caucho.server.deploy.DeployController.startOnInit(DeployController.java:451) at com.caucho.server.deploy.DeployContainer.start(DeployContainer.java:157) at com.caucho.server.webapp.ApplicationContainer.start(ApplicationContainer.java:610) at com.caucho.server.host.Host.start(Host.java:385) at com.caucho.server.deploy.DeployController.startImpl(DeployController.java:563) at com.caucho.server.deploy.StartAutoRedeployAutoStrategy.startOnInit(StartAutoRedeployAutoStrategy.java:72) at com.caucho.server.deploy.DeployController.startOnInit(DeployController.java:451) at com.caucho.server.deploy.DeployContainer.start(DeployContainer.java:157) at com.caucho.server.host.HostContainer.start(HostContainer.java:468) at com.caucho.server.resin.ServletServer.start(ServletServer.java:934) at com.caucho.server.deploy.DeployController.startImpl(DeployController.java:563) at com.caucho.server.deploy.AbstractDeployControllerStrategy.start(AbstractDeployControllerStrategy.java:56) at com.caucho.server.deploy.DeployController.start(DeployController.java:459) at com.caucho.server.resin.ResinServer.start(ResinServer.java:465) at com.caucho.server.resin.Resin.init(Resin.java) at com.caucho.server.resin.Resin.main(Resin.java:612) (ii) 14:33:23,196 WARN resin-tcp-connection-*:8080-1 RequestUtils:createActionForm:177 - No FormBeanConfig found under 'view' 14:33:29,190 WARN resin-tcp-connection-*:8080-1 http://127.0.0.1:8080/xwiki/bin/view/Main/WebHome Configurator:configure:126 - No configuration found.

Bad code displqy design
by Jim Stuttard 12 Aug '05

12 Aug '05

Hi, The scrollable box uggh i which you display code snippets is never as wide as its containing box and thus usually has both horizontal and vertical scroll bars uggh. This is very bad ui design. Code is impossible to read easily and the select and copy. Scroll bars should be avoided whenever possible. WDYT? Cheer Jim -- Jim Stuttard

Re: DB2 and XWIKI
by Ludovic Dubost 12 Aug '05

Hi, Thanks for the compliments on xwiki ! Well, database porting should be discussed on the developers list ( http://forge.objectweb.org/mail/?group_id=170 ) and added to the xwiki page on databases ( http://www.xwiki.org/xwiki/bin/view/Dev/Database+Porting ) Concerning your errors, it doesn't look good.. it seems hibernate is chocking while looking at the capabilities of the DB2 driver.. However when I look at this ( http://www-128.ibm.com/developerworks/db2/library/techarticle/0306bhogal/03… ) it seems it should work. Maybe it fails on something specific in the mapping.. So you might want to remove each column from the xwiki.hbm.xml file until it works to see what is the cause. Maybe a simple change in the mapping can make it work with B2 without breaking xwiki..
