JAXB Compile Failure

When compile my code that uses JAXB with JDK1.5, I got an error "cannot access javax.xml.stream.XMLEventReader". There is no such error if I compile it with JDK1.6. The way to fix it is to include jsr173_api.jar in the classpath along with jaxb-api.jar, jaxb-impl.jar and jaxb1-impl.jar. This class javax.xml.stream.XMLEventReader is part of JDk1.6, that is why the compiling issue only happens to JDK1.5.

Install JDeveloper on Mac

There is a very important trick to play before installing Oracle JDeveloper on a Mac. Basically you need to fool the JDEV installer to believe the java on your Mac is like those on Unix/Linux box.

cd /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home/
sudo mkdir -p jre/lib
cd jre/lib
sudo ln -s ../../../Classes/classes.jar rt.jar

This step was actually on Installation Guide for Oracle JDeveloper

Snow Leopard

Days ago, I ownloaded an app. The installation failed because it is for Snow Leopard. I then realized that Mac OS X 10.6 had been released for a while, actually a year ago. I thought I should upgrade my macbook. It worked great, but should I give Snow Leopard a try?

20K

Yesterday I finished my first 20K trail run at Oakland Redwood Regional Park. I was surprised, I was totally impressed by myself. I am so proud of my time, less than 1:50 http://ultrasignup.com/results_event.aspx?did=8951. My best estimation before the race was within 2:30, as I neither run a long distance like this nor run a trail. Actually I hoped I could finish it by 3 hours.

Let me tell you how difficult it was. The elevation gain is 1,720 feet. Especially it started raining heavily for 20-30 minutes right before the race beginning. The trail was slippery and mud sticked to my shoes, made them not just wet but also much heavier. And it was cold. I should have worn a pair of gloves. But it was fun, a serous fun in Mother's day. Happy Mother's Day!

Notifications to OpenSSO Client

Someone found that distauth of Opensso cannot recieve session notifications from opensso server. My investigation showed that a new property "com.sun.identity.client.notification.url" was not set in AMConfig.properties of the distauth. This property is new to Opensso, somehow it was not there by default. If you want your opensso client to receive notifications from the session service, policy service and UM on the server, you need to add it.

See more details on DocTeger's blog.

CVS Branch Move, Delete and Rename

Today I have to move a cvs branch on a file. The cvs branch was created yesterday, but there was a new checkin needs to go into the branch. Instead of checking into the new branch, one can move the branch tag on that specific file. For example, to tag on revision 1.6 of a file

cvs tag -r 1.6 -F branch_tag file_name

CHP With Multiple Agents Instances

Recently a bug was identified in OpenSSO8.0 code related to Cookie Hijack Prevention (CHP). There are multiple policy agent instances with a Load Balancer (LB) in front. In this case, agent profiles must have LB URL added in the agent root URL list (CDSSO + CHP). However, a strange behavior could be observed. Only one agent works, you could see your browser spinning when accessing other agents. This is OpenSSO issue 5707.

Lotus Touts

My kid sent me this circulating email talking about some Lotus Touts. I don't like email chain letters, but the Lotus Touts in this one is nice. I would like to follow this guidance if it is not too late.

FIVE. When you say, 'I'm sorry,' look the person in the eye..

Reset Amadmin Password (2)

In my previous post (09/11) on this topic, I asked to have jss4.jar in the classpath and have corresponding library files in the environment. Actually it is not required. Otherwise, one will have a hard time to find and install them on a windows box. All you need to do is to set the value of property com.iplanet.security.encryptor to be "com.iplanet.services.util.JCEEncryption". The default is "com.iplanet.services.util.JSSEncryption" if you don't specify, which requires JSS.

So the command to generate new password could be looked like
/usr/bin/java -Dcom.iplanet.security.encryptor=com.iplanet.services.util.JCEEncryption -Dam.encryption.pwd=sZ6rTm4Dp1xp6MuXpwyQ3h0RsdcMK5eQ -cp .:/opt/sun/identity/lib/am_sdk.jar:/opt/sun/identity/lib/am_services.jar PasswordHashEncryption password
