NHibernate.MappingException: No persister for: HelloNHibernate.vo.People

I am testing NHibnernate these days, but I get this kind of error message NHibernate.MappingException: No persister for: HelloNHibernate.vo.People

The cs name, package name are correct, but the console still report this error message.

Finally, I found out the root cause: all mapping files should be set Embedded Resource, then it can execture correctly.

ORA-00932: inconsistent datatypes: expected - got CLOB

As I am doing data query with distinct syntax in select clause, I got this error message:
ORA-00932: inconsistent datatypes: expected - got CLOB

This error message result from Clob limitation:

1. CLOBs don't work like strings. You can't ask for the LENGTH of a CLOB column, for example. You can work around this with PL/SQL calls but it isn't much fun.
2. LOBs are not allowed in GROUP BY, ORDER BY, SELECT DISTINCT, aggregates and JOINS

Therefore, I re-designed my database schema. Save this CLOB column into another table.

ORA-01502 Oracle Index in Unusable State

As I execute sql statement to do search, it return this message unexpectedly:ORA-01502: index 'RSDB.RESUME_PK' or partition of such index is in unusable state

Solution: rebuild this index

ALTER INDEX RESUME_PK REBUILD

After I executed this rebuild action, it turned out to be normal.

Utilize Quartz to Implement Scheduling Service

Scenario


Implementation Process


http://www.slideshare.net/junyuo/utilize-quartz-to-implement-scheduling-service

PMD

PMD scans Java source code and looks for potential problems like:

• Possible bugs - empty try/catch/finally/switch statements
• Dead code - unused local variables, parameters and private methods
• Suboptimal code - wasteful String/StringBuffer usage
• Overcomplicated expressions - unnecessary if statements, for loops that could be while loops
• Duplicate code - copied/pasted code means copied/pasted bugs

It can be plug-in to Eclipse, NetBeans, etc.

NamedQuery of name: jobDutyJobTitle.findByJobDuty not found.

As I used JPA as my persistence tier implementation. I declared a named query in my entity class:










And I called this name query in my DAO class:

Troubleshooting on Tomahawk JSCook Menu

http://wiki.apache.org/myfaces/JSCook_Menu

Check Notes and Known issues.
I had faced this issue Place of Menu tag in relation to Forms:
Menus must be placed inside forms starting with Tomahawk 1.1.3.
With regard to how to do configuration in web.xml, please check http://myfaces.apache.org/tomahawk/extensionsFilter.html

java.lang.IllegalStateException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered.

Error Message

1 2 3 4 5 6 7

java.lang.IllegalStateException: ExtensionsFilter not correctly configured. JSF mapping missing. JSF pages not covered. Please see: http://myfaces.apache.org/tomahawk/extensionsFilter.html at org.apache.myfaces.renderkit.html.util.AddResourceFactory.throwExtensionsFilterMissing(AddResourceFactory.java:389) at org.apache.myfaces.renderkit.html.util.AddResourceFactory.checkEnvironment(AddResourceFactory.java:349) at org.apache.myfaces.renderkit.html.util.AddResourceFactory.getInstance(AddResourceFactory.java:279) at org.apache.myfaces.custom.navmenu.jscookmenu.HtmlJSCookMenuRenderer.addResourcesToHeader(HtmlJSCookMenuRenderer.java:404) at org.apache.myfaces.custom.navmenu.jscookmenu.HtmlJSCookMenuRenderer.encodeBegin(HtmlJSCookMenuRenderer.java:363) at javax.faces.component.UIComponentBase.encodeBegin(UIComponentBase.java:788)

Solution
If you are using servlets 2.4, you cannot do a jsp:forward or request.getDispatcher().forward to any page, because the extensions filter is not executed. Instead you may want to try with a response.sendRedirect(). Therefore, I need to modify to response.sendRedirect("template-client.jsf");

Highlighting Odd and Even Rows in JasperReports - Brian Burridge

Highlighting Odd and Even Rows in JasperReports - Brian Burridge: "new Boolean( $V{PAGE_COUNT}.intValue() % 2 ==0 )"

In order to highlight odd or even rows with a background color, in JasperReports, first create a rectangle element with a background of your color choice, and send it to the background (in JasperAssistant, right click on the rectangle, choose Arrange and then Send to Back). Second, use the following expression to set when the element should appear, by placing the expression in the Print When Expression field of the rectangle element. Where the $V{PAGE_COUNT} appears, you can use that, to base it on the row number on the page, or use $V{REPORT_COUNT} to base it on the row within the report. Also, if you are using a group, you can use $V{groupname_COUNT} where groupname is replaced with the name of your group. The expression below will then test the row number within the Page, Report, or Group (whichever you selected) and if its divisible by 2, it will display the rectangle element with the background color.

40 Reasons Why Software Projects Die

http://sourcemaking.com/antipatterns

Ports and protocol which had been used by Windchill

Http: 80
JavaRMIServlet: 5001~5010
ProjectLink Meeting port: 5620~5660

Therefore, network administrator should open these ports.

Check Windchill failed queue how-to

1. Go to Site tag and click Utils
2. Go to Queue Manager page
3. Choose failed queue, ex. WfUserWorkQueue
4. pickup one queue entry which had been marked as server, and select 'show' option in dropdown list
5. check error message, ex. wt.workflow.robots.WfInternalMethod:135596
6. used sql statement to figure out which object cause this failed queue.
select t2.businessobjreference, t2.name from WfInternalMethod t1, wfprocess t2 where t1.ida2a2 = 135596 and t1.ida3parentprocessref = t2.ida2a2
7. we can get information from step6.
businessobjreference is VR:wt.doc.WTDocument:136558
name is TPV - Release Workflow_0000000046 - Electronic Component Sample Request Operation Quide A
8. go to search page: apply 0000000046 to number to be our search criteria,
then we can check the related workflow to check what's wrong

4. Load ACL, execute command: windchill wt.load.WindchillLoader -Application=Windchill.PartsLink

Windchill Quick Backup

Procedure

1. backup applicationa & configuration, i.e. D:\PTC\Windchill8\codebase

2. backup database, i.e. execute command: exp pdm8/pdm8@WINDDEV file=D:\tmp\database\WINDDEV.dmp log=D:\tmp\database\WINDDEV.log

If any problem occurred, just overwrite codebase and do database import to do system recovery

Windchill Change Password

In past, Windchill does not provide change password function.
Many customers will complain about this.
Now, Windchill 8 M040 had provided.
But default, M040 disabled change password function, we need to turn it on.

Process:
1. define in site.xconf

1 2 3

<property name="wt.org.services.userPasswordChangeEnabled" overridable="true" targetfile="codebase/wt.properties" value="true">

2. execute xconfmanager -p in windchill shell

3. restart tomcat, method server. And do not forgot to clean tomcat cache.

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

[SVN] mod_dav_svn.so is garbled- perhaps this is not an Apache module DSO

Error Message
httpd: Syntax error on line 115 of D:/Program Files/Apache Software Foundation/Apache2.2/conf/httpd.conf: API module structure `dav_svn_module' in file D:/Program Files/Apache Software Foundation/Apache2.2/modules/mod_dav_svn.so is garbled- perhaps this is not an Apache module DSO?


Resolution
Owning to the apache version is 2.2, it will report this kind of error message. Just change the apache version to 2.0, then this kind of error will disappear.
