[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));

[Windchill] Build ResourceBundle How-To

If I edit some texts in reportResource.rbInfo, how do I build this resource bundle.

Steps.
1. open windchill shell window
2. utilize ResourceBuild
Example Usage: ResourceBuild D:\ptc\Windchill\src\wt\fc or ResourceBuild wt.fc.fcResource
--Arg1 specifies which directory or class to generate.
--Arg2 specifies if locale specific resource will be built.
--values for arguments not passed will be obtained from tools.properties.

then input the command as bellows:
ResourceBuild ext.fusheng.report.reportResource true

execution info:
D:\ptc\Windchill>echo off

[HTML / JS] View formatted source (format source extension)

https://addons.mozilla.org/firefox/697/

Displays formatted and color-coded source and optional CSS information for each element.

You can see exactly which CSS rules match for an element. The rules are displayed including file name and line number. The topmost element is that with the highest priority.

You can fold/unfold/hilite block elements (table, tr, td, div, span,...). Really cool feature: select a block level element of interest directly in the page and view it's source! To help you to quickly analyze the source code you can view images directly from the source and add comments to folded block elements. The code view is based on the rendered document, so you will also see dynamically (by Javascript) created and modified html elements! Works also with frames and selected text.

[Windchill] Cannot do copy & paste in Applet

Scenario
As I do some operation in Windchill, because of some user interface was done by applet, it is inconvenience for us if we wolud like to copy some texts then paste them into the applet.

Solution
It is the security constraints so we cannot do copy and paster in applet window.
We can find out the java.policy file in JRE\lib\security, then append this declaration as bellows:

grant codeBase "http://hostname/Windchill/-" {
permission java.security.AllPermission;
};

[ANT] Date of 05/28/2006 07:06 午後 Cannot be parsed correctly. It should be in MM/DD/YYYY HH:MM AM_PM format


Scenario

As I utilized ant to build program, it throwed exception as bellows:
D:\ptc\Windchill_8.0\customization\wtinstaller.xml:234: Date of 05/28/2006 07:06 午後 Cannot be parsed correctly. It should be in MM/DD/YYYY HH:MM AM_PM format.

About the timestamp in the build script is written as bellows:
<tstamp><format property="myDateTime" pattern="MM/dd/yyyy hh:mm aa"
offset="-${sinceDays}" unit="day" /></tstamp>

Solution
Owing to the locale of my environment is Japane, so it will show this kind of error message, we just need to add locale attribute to this element, and set it to be en, then we can resolve this kind of problem.
<tstamp><format property="myDateTime" pattern="MM/dd/yyyy hh:mm aa"
offset="-${sinceDays}" unit="day" locale="en"/></tstamp>

[Windchill] java.rmi.ConnectException: Connection refused to host

Scenario
As I start the method server, it always throw this kind of exception message as bellows and the method server always cannot be start properly:

星期一 5/22/06 16:31:49: main: Warning: exception connecting to master LogicalIdentifierCacheMgr:
星期一 5/22/06 16:31:49: main: java.rmi.ConnectException: Connection refused to host: albert.ptcnet.ptc.com; nested exception is:
星期一 5/22/06 16:31:49: main: java.net.ConnectException: Connection timed out: connect


Solution
According to the wt.properties, it said that windchill use port 5001. But as I telnet it, telnet albert.ptcnet.ptc.com 5001, it cannot be connect it.
It may result from that port 5001 had been occupied by another applications or this port had been blocked by firewall, so I change the port from 5001 to 5002, then the problem had been resolved successfully.

[Windchill] com.infoengine.au.ServiceUnavailableException

Scenario
As I start method server, it throws this kind of exception as bellows. And when I click the Product tab in the windchill, it will produce the same exception:

Solution
Owning to the service which named
com.ptc.ptcnet.albert.server.taskProcessor does not exist, so it will produce this kind of exception in the method server console.


Change the value of ptcServiceName of com.ptc.ptcnet.albert.Windchill in LDAP.

[Tomcat] Disable Tomcat Cache

Scenario
As I author jsp files, no matter how I refresh the browser, it always show old data. It's inconvenient for us to do debug

<init-param>
<param-name>development</param-name>
<param-value>true</param-value>
</init-param>


But remember to change the value of development to false for the sake of performance.
