Java 2 Software Development Kit (J2SE SDK) - the new jre isn't working

Scenario
I have instaled the new j2se development kit 5.0 and jre5.0, but my browser cannot open any applet and Sun Java console. The error is ---- " The Java Runtime Environment cannot be loaded from <\bin\server\jvm.dll> ???!!!

Solution
In your "Documents and Settings\username\Application Data" folder you'll probably find a folder named "Sun". Delete that folder (or rename it).

[Windchill] How to generate mData

Steps.
1. open rose
2. Tools --> Windchill --> System Generation
3. Click OK

Troubleshoot
It may show generation refuse error in the progress of system generation
Error: wt.templateutil.processor.DefaultTemplateProcessor is not Extendable, so cannot extend it.

Solution
1. Open user.properties (under /Codebase)
2. add one attribute wihch named wt.generation.overrideNonExtendableClasses, and add classes which we want to do extend. If we have multiple classes need to do extend, sperate them by comma.
ex. wt.generation.overrideNonExtendableClasses=wt.templateutil.processor.DefaultTemplateProcessor,wt.templateutil.processor.FormTaskDelegate
After you add them to user.properties, you can see this kind of warning message, it means you had successfully finished system generation.
Warning: wt.templateutil.processor.DefaultTemplateProcessor is not Extendable, but is being allowed as a backward compatible override

[Mail] commons-mail 亂碼問題

[常見問題1]sent出去的mail的中文標題變成亂碼

呼叫setCharset此方法，設定編碼方式為UTF-8

public void setCharset(java.lang.String newCharset)

http://jakarta.apache.org/commons/email/api-release/org/apache/commons/mail/Email.html#setCharset(java.lang.String)

[常見問題2]sent出去的mail的中文內文便成亂碼

呼叫setContent此方法，第一個參數給予訊息內容，第二個參數給予conent type，例如text/plain;charset=UTF-8

public void setContent(java.lang.Object aObject,
                  java.lang.String aContentType)

http://jakarta.apache.org/commons/email/api-release/org/apache/commons/mail/Email.html#setContent(java.lang.Object,%20java.lang.String)

[常見問題3]sent出去的附件中文檔名變成亂碼

在EmailAttachment的物件中的setName方法中，使用MimeUtility的encodeText方法
attachment.setName(MimeUtility.encodeText("中文訊息", "UTF-8", null));
