lunalovegood — Tue, 29 Dec 2009 11:53:20 +0800

What the heck is this? i googled everywhere but no answer. i'm using oracle portal. it was ok when i run it locally and through the web, but when i tried to run it in the portal it says "The website cannot display the page" and the log says this:

CODE

saveOrUpdate() composite id in hibernate

lunalovegood — Fri, 11 Dec 2009 19:32:46 +0800

i have a table with a composite key

here's the hibernate mapping:

CODE

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping>
<class name="packagename.vo.ValueObjectClass"
table="TABLENAME">
<composite-id>
<key-property name="Code" column="CODE" type="string" />
<key-property name="levelCode" column="LEVELCODE" type="string"/>
<key-property name="countryCode" column="COUNTRYCODE" type="string"/>
</composite-id>
<property name="durationMonth" column="DURATIONMONTH" type="integer"/>
<property name="totalAmount" column="TOTALAMOUNT" type="integer"/>
</class>
</hibernate-mapping>

and this is where i called the saveOrUpdate() method :

CODE

public void saveToDatabase(ValueObjectClass voc){
logger.debug("inside saveToDatabase");
super.getHibernateTemplate().saveOrUpdate(smdvo);
logger.debug("Leaving saveToDatabase");
}

but the thing is the program only saved one item into the table. i googled and i found out from hibernate forum that i can use saveOrUpdate for composite id but i just cant find the way how.

DILBERT by Scott Adams

lunalovegood — Fri, 11 Dec 2009 11:41:17 +0800

what should i say about dilbert?i just like how Scott Adams almost realistically gives us today's working environment in a simple strip. i can relate with most of dilbert's everyday anguish at workplace. on a normal stressful day at work, just read a few strips, and i'm ready for another 9 rounds. haha.

I got my daily dose of dilbert here.
The official Dilbert website with Scott Adams' color comic strips, animation, mashups and more!

THE FIRST DILBERT STRIP IN April 17, 1989. XD

Any other Dilbert fans here?

hibernate

lunalovegood — Thu, 26 Nov 2009 11:56:07 +0800

i dunno what's the problem i might be missing or overlook something, but i just cant figure out why my hibernate wont work. here's my code:

CODE

public void saveProgram(CreateProgramModel model) {
SponsorshipProgramVO spvo = new SponsorshipProgramVO();

spvo.setSponsorshipProgramCode(model.getProgramCode());
spvo.setName(model.getProgramName());
createProgramDao.saveToSponsorshipProgram(spvo);
}

public void saveToSponsorshipProgram(SponsorshipProgramVO spvo){
logger.debug("inside saveToDb");
super.getHibernateTemplate().save(spvo);
logger.debug("Leaving savetodb");
}

and this is the query generated, i got it from my log.

CODE

insert into SPONSORSHIPPROGRAM (NAME, NAMESHORT, DESCRIPTION, SPONSORSHIPTYPECODE, CONTRACTREQUIREMENTCODE, SPONSORSHIPSTATUSCODE, SPONSORSHIPSTATUSDATE, FUNDINGTERMCODE, CONTRACTMONTH, GUARANTORREQRCODE, STARTDATEEXPECTED, STARTDATEEND, SPONSORSHIPPROGRAMCODE) values (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)

it seems like the values wont bind. i check the values sent form the form is there in the session.

please help me. i havent had enough sleep for days because of this.

Paediatricians

lunalovegood — Fri, 16 Oct 2009 13:03:50 +0800

i have a three months baby. for the past 3 months, we went to 3 different clinic for her injections. i'd like to stick to one only, but circumstances always prevent me from doing so. the first two was normal clinics, the last one was paediatrician clinic, the only one i know because i went there back when i was a child. we went there so i can get her the pneumococcal vaccine,because normal clinics dont have them. the vaccine cost me rm300 and then plus with the other injections (the 5 serangkai injection) rm130, it'll cost me rm430 in total. i dont mind it, but my husband thinks its too expensive.

is it? does anyone here knows where can i find any other paeds around KL or SELANGOR? i know theres a lot, but i just need opinions from the people who already went there and how much is the cost for the pneumococcal vaccine. thanks very much in advance.

onchange="submitForm('table');">
<c:forEach var="t" items="${mergingcmd.sourceTableNames}">
<option value="<c:out value='${t}'/>">
<c:out value="${t}"/>
</option>
</c:forEach>
</select>
</spring:bind>
</td>
</tr>
</c:forEach>

nested iterator

lunalovegood — Thu, 12 Feb 2009 12:47:49 +0800

right now an execution of a piece of winding codes takes more than a minute as the data is more than a thousand rows.

i'm unable to post the code itself as i keep getting error saying my post is too long.

i want to know if the existence of too many nested iterator can cause this problem.

anyone here care to give their thought on this?

how to print on A6 size paper continuously?

lunalovegood — Wed, 14 Jan 2009 16:14:38 +0800

hi,
i'm using iReport to generate reports from an erp system. currently i'm facing problem printing it on A6 size paper. i want the report to be printed continuously on A6 paper until the report finishes. i already set the size for the report which supposed to fit an A6 size paper. which look like this:

[attachmentid=762438]

this one box represents one whole row of data, so if i have 100 rows of data, it should print 100 of this box, which means 100 pages of A6 size paper. Get what i mean?
but the thing is right now it skips 2 pages for each print. 1 page print, 2 none, 1 page print, 2 none and it continues like that until the report finish. i suspected the it was because i use pdf format to view the report before printing it. but i'm not too sure.

can anyone here help?? please.. i've tried fixing this for months already.

need help hibernating

lunalovegood — Sat, 07 Jun 2008 09:26:52 +0800

CODE

public List findUserForModule(String moduleName, String userName) {
logger.info("Performing query for username " + userName + " and module " + moduleName);
String query = "from PrivilegesModuleModel pmod, PrivilegesUserModel pusr, PrivilegesMapModel pmap ";
query += "where pusr.userName = :userName and pmod.moduleName = :moduleName ";
query += "and pusr.privilegesUser_id = pmap.privilegesUser_id ";
query += "and pmod.privilegesModule_id = pmap.privilegesModule_id";
String[] paramNames = new String[] {
"moduleName",
"userName"
};
Object[] paramValues = new Object[] {
moduleName,
userName
};
return getHibernateTemplate().findByNamedParam(query, paramNames, paramValues);
}

i keep getting ClassNotFoundException, is there something wrong with the query? i've checked the classes are where they are suppose to be, at least i think so.

Cant connect to wireless network

lunalovegood — Mon, 28 Apr 2008 16:07:27 +0800

Its my friends notebook. Been trying since this morning. Our supervisor said that there's a probability she got a program inside the notebook that block the connection. It says connected, but nobody's home! Anyway, in the Wireless Event Viewer, got an error that says "MurocApi: 802.1x Config". What's that? We tried googling it, not much answer. Can anyone help?

computer or software engineering?

lunalovegood — Mon, 24 Mar 2008 02:19:37 +0800

uh... right now i'm in my last semester for Dip. in Comp. Sci., if evrything goes smoothly i will further to degree probably in July as most unis got july intake. i already filled up those application forms, and yesterday i saw an ad frm unikl offering bachelor courses such as comp and software engineering. I've always been interested in computer engineering, bt i think i pretty much lack the technical skill. most of my study only revolve around programming and techie stuff limited to fixing my own pc.
I'm wondering if u guys can give ur opinion on this.

mySql

lunalovegood — Tue, 12 Feb 2008 14:02:09 +0800

dunno hw to ask this..damn noob la.. huhu.
i'm using java spring framework here, i need to delete a specific data, from a row of data.

this is the code i use to delete one whole row of data,

CODE

public void deleteByCode(String code) {

DetachedCriteria criteria = DetachedCriteria.forClass(SomethingVO.class);
Criterion expr = Restrictions.eq("codeColumn",code);
criteria.add(expr);
List result = super.getHibernateTemplate().findByCriteria(criteria);
super.getHibernateTemplate().delete(result.get(0));

}

bt now i want to delete a specific data but not from a specific column. am i saying it correctly? like search the row if got this data inside it, and if got, delete the data only, not the whole row.

jdbc + oracle

lunalovegood — Fri, 07 Dec 2007 10:58:23 +0800

is there something wrong?

CODE

private Connection getConnection() throws NamingException, SQLException
{
javax.naming.InitialContext ctx = new InitialContext();
javax.sql.DataSource datasource = (DataSource)ctx.lookup("jdbc/Saturn");
Connection conn = datasource.getConnection();
return conn;

}

public void save(UserModel model)
{
String updateStatement = "UPDATE NATRAH SET NAME=? , IC=? , ADRRESSS1=? , ADRRESS2=? , ADRRESSS3=? , ADRRESSS4=? WHERE USER_ID=? ";//NUMBER_TEST is the table inside the db
String insertStatement = "INSERT INTO NUMBER_TEST(NAME,USER_ID,IC,ADRRESSS1,ADRRESSS2,ADRRESSS3,ADRRESSS4) VALUES(?,?,?,?,?,?,?) ";

Connection conn = null;

try
{
//create connection
conn = getConnection();
System.out.println("open connection"); //<<--------------------------------------------line1

//update DB

PreparedStatement ps1 = conn.prepareStatement(updateStatement);
ps1.setString(1,model.getName());
ps1.setString(2,model.getIc_number());
ps1.setString(3,model.getAdd1());
ps1.setString(4,model.getAdd2());
ps1.setString(5,model.getAdd3());
ps1.setString(6,model.getAdd4());
ps1.setString(7,model.getUser_id());

int noOfRecordUpdated = ps1.executeUpdate();

if(noOfRecordUpdated==0)
{
//Insert to DB
PreparedStatement ps2 = conn.prepareStatement(insertStatement);
ps2.setString(1,model.getName());
ps2.setString(2,model.getUser_id());
ps2.setString(3,model.getIc_number());
ps2.setString(3,model.getAdd1());
ps2.setString(4,model.getAdd2());
ps2.setString(5,model.getAdd3());
ps2.setString(6,model.getAdd4());

ps2.executeUpdate();

}//end if

}// end of try

catch (Exception e)
{
System.out.println("ERROR1"); // <<--------------------line2
}
finally
{
try{
if(conn != null)
conn.close(); //close connection
System.out.println("close connection"); //<<-----------line3
}
catch (Exception ignore){}
}

}

the connection seems like it isnt even open, the code in "line 1" - System.out.println("open connection"); wsnt executed, instead on "line 2" - System.out.println("ERROR1"); and on "line 3" - System.out.println("close connection"); was executd.

b4 this i'v written another almost similar coding, and it worked well.

CODE

public void save(NumberModel model)
{
String updateStatement = "UPDATE NUMBER_TEST SET INPUT1=? , INPUT2=? WHERE USER_NAME=? ";//NUMBER_TEST is the table inside the db
String insertStatement = "INSERT INTO NUMBER_TEST(USER_NAME,INPUT1,INPUT2) VALUES(?,?,?) ";

//to ensure the connection is close enter everything into 'try'
Connection conn = null;

try
{
//create connection
conn = getConnection();
System.out.println("open connection");

//update DB

PreparedStatement ps1 = conn.prepareStatement(updateStatement);
ps1.setInt(1,model.getInput1());
ps1.setInt(2,model.getInput2());
ps1.setString(3,"me");

int noOfRecordUpdated = ps1.executeUpdate();

//if no record updated:insert DB
if(noOfRecordUpdated==0)
{
//Insert DB
PreparedStatement ps2 = conn.prepareStatement(insertStatement);
ps2.setString(1,"me");
ps2.setInt(2,model.getInput1());
ps2.setInt(3,model.getInput2());

ps2.executeUpdate();

}//end if
//if no record updated:insert DB

}// end of try

catch (Exception e)
{
System.out.println("ERROR1");//comment smthng smthng
}
finally
{
try{
if(conn != null)
conn.close(); //close connection
}
catch (Exception ignore){}
}
//to ensure the connection is close
}

today is my 5th day working, meaning only 5 days worth of experience with jdbc+oracle and whatnot. i've been working on this thing since yesterday. huhu.
