hibernate error

[Mark Hughes]

Hey guys im trying to get a simple hibernate example goin, just a main java class, a class for set & get methods and 2 xml files for mapping and stuff.
But when i compile the program has trouble creating the session and it remains null.
This is the error i get

23-Aug-2006 09:47:03 org.hibernate.cfg.Environment <clinit>

Im afraid it does not mean much to me and im pretty sure its a configuration error, can any teach me exactly why the error might be occuring or what file could be causing the problem?

any idea's

[Paul Sturrock]

INFO: Reading mappings from resource: roseindia/tutorial/hibernate/Contact.hbm.xml
org.hibernate.MappingException: Resource: roseindia/tutorial/hibernate/Contact.hbm.xml not found

Contact.hbm.xml is not in the classpath, so Hibernate can't find it. Check it exists, is on the classpath and is in the package roseindia/tutorial/hibernate.

(Your earlier error look like: 1) hibernate.cfg.xml didn't exist or wasn't on the classpath, & 2) hibernate.cfg.xml wasn't valid XML

[Mark Hughes]

i had it in a bin folder, that was in my project but not directly in the package,

When i put the contact.hbm.xml in the package folder the error changed again to

so hard to know what these errors mean!

[Paul Sturrock]

A NoClassDefFoundError means that a class required by some application code cannot be found. In this case that class is called org.apache.commons.collections.SequencedHashMap which is part of commons collections. So the commons collections jar file must be in your classpath toio.

[Mark Hughes]

were getting there, more program errors now so on the right track.

Would this be the xml file yea or contact.class file?

Mark

[Paul Sturrock]

org.hibernate.MappingException: Repeated column in mapping for entity: roseindia.tutorial.hibernate.Contact column: Price (should be mapped with insert="false" update="false")

The error message tells you it is in the mapping file. Just fix the mapping so it:

Just has one property mapped to the column price

Or only has one property mapped to the column price with the attributes insert and update = "true".

[Mark Hughes]

Hey,


Here is the mapping file contents:

 
<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC 
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
 
<hibernate-mapping>
  <class name="roseindia.tutorial.hibernate.Contact" table="cost">
   <id name="Price" type="Varchar" column="Price" >
   <generator class="assigned"/>
  </id>
 
  <property name="Price">
     <column name="Price" />
  </property>
  <property name="Tax">
    <column name="Tax"/>
  </property>
  <property name="Total">
    <column name="Total"/>
  </property>
 </class>
</hibernate-mapping>

My database is called test and the table is called cost, with columns Price, Tax and Total. All the tutorial program is doing is updating so i should change <generator class="assigned"/> to update yea and what else did you say so i understand

Mark

[Paul Sturrock]

<id name="Price" type="Varchar" column="Price" >   
  <generator class="assigned"/>  
</id>   
<property name="Price">     
  <column name="Price" />  
</property>

You have a property called Price that is mapped to the price column. You have also mapped this column as the primary key. Remove the property mapping and everything should work.

[Mark Hughes]

ok i removed property


<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="roseindia.tutorial.hibernate.Contact" table="cost">
<id name="Price" type="Varchar" column="Price" >

</property>
<property name="Tax">
<column name="Tax"/>
</property>
<property name="Total">
<column name="Total"/>
</property>
</class>
</hibernate-mapping>

but then got error that it could not find class

I guess i done it wrong, did i? Sorry i dont quite understand it fully

[Paul Sturrock]

SEVERE: Error parsing XML: XML InputStream(14) The element type "class" must be terminated by the matching end-tag "</class>".

Your mapping file is not valid XML. XML must be well formed; all opening elements must be closed. You have only removed part of the price property element. Remove it completely.

[Mark Hughes]

Sorry again, ive a good feeling that we are nearly there,

i changed the file to;

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="roseindia.tutorial.hibernate.Contact" table="cost">
<id name="Price" type="varchar" column="Price" >
<generator class="update"/>
</id>
<property name="Tax">
<column name="Tax"/>
</property>
<property name="Total">
<column name="Total"/>
</property>
</class>
</hibernate-mapping>

which corrected the problem, but the compiler does not understand what
<id name="Price" type="varchar" column="Price" >

type ="varchar" is.

error: Could not determine type for: varchar, for columns: [org.hibernate.mapping.Column(Price)]

i tryed upper and lower case, then kinda ran out of ideas, does not appear to be an instruction part of hivernate that tells ya what types it understands?

[Mark Hughes]

ok i changed varchar to string and solved prob, so i assume that must match the variables in the class and not the database. and it gave more errors but i think they are just missing classes so ill carry on and leave ya know what the story is

[Paul Sturrock]

so i assume that must match the variables in the class and not the database

Yes. It is the responsibility of the Dialect to map between Java types and SQL data types, so you don't need this info in the mapping file.

[Mark Hughes]

oh so i could remove type="string" from the mapping file altogether.

and oh yea ofcourse i have new errors, ive never in my life gone from one error to another so many times in a tutorial typr prog, then again im really learning alot.

error:

What ya think?

[Paul Sturrock]

oh so i could remove type="string" from the mapping file altogether.

No. You need to include the type of the property, but you should not be including the SQL datatype. After all, one of Hibernate's purposes in life is to abstract away the various vagueries of vendor specific data types. If you had to include the data type in your mapping, you would loose some of that abstraction.

<id name="Price" type="varchar" column="Price" >
<generator class="update"/>
</id>

You will need to give your ID a valid generator class as per the Hibernate documentation. "update" is not a supported primary key generation strategy.

[Mark Hughes]

ah great stuff i understand.

Ok for the life of me i cant seem to find this .jar to download.
the error is: Exception in thread "main" java.lang.NoClassDefFoundError: javax/transaction/Synchronization.

Do you know what api its from?

[Paul Sturrock]

That is part of JTA, with forms part of J2EE. Are you using JTA as your transaction mechanism? If so you'll need j2ee.jar in your classpath too.

[Mark Hughes]

to be honest i dont believe i am using that as a transaction mechanism, i only have 2 class files with the intention of updating a database with 3 attributes using the set methods of my class. Very simple stuff i though id have it done hour and half tops, theres alot of configuration to get through i must say.
Sure ill include the jar and see what happens. Thansk for all your help so far, very good

[kumari Jain]

hi Mark,
The tutorial at the hibernate site is very good.I was able to execute the first example very easily.May be you can take look at this tutorial -

http://www.hibernate.org/hib_docs/v3/reference/en/html/tutorial.html

Regarding your jar problem,Synchronization class file is found in jta.jar

All the required jars for hibernate come bundled in one jar file.This can be downloaded from here

http://hibernate.org/6.html

You can download either one of the jar under Hibernate Core package.
Hope this helps.

regards,
kumari

[Mark Hughes]

Hey Paul and Kumari,

Thanks for all the input and help, great stuff, i eventually got what i thought all the errors and stuff and it compiled and executed as it was supposed to but im afraid it still contained exceptions and did not update the database.

as you can see its alot of information, i may just go and try the hibernate tutorial. This one seems to be a lost cause, what ya think?

[Mark Hughes]

i added some more jars that the hibernate example wanted and got this result,

a
log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
b
c
Inserting Record
Done
Hibernate: insert into cost (Tax, Total, Price) values (?, ?, ?)


dont mind the a b c i just put them in earlier to see how far the program was getting.

Any advice?

[Paul Sturrock]

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

This warning is telling you you have not configured log4j correctly. See the documentation on the log4j websiteto see what to do.

[Mark Hughes]

Hey,
Ok i removed log4j from the project as i dont believe it depends on it to work and im not using it anyway, so one last thing before i give up, my other post of the hugely massive message. What do you make of that, the post directly before the log4j error.

Sorry again, i know its kinda getting ridiculous now.

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

-------------- Ignore everything above this, it has nothing to do with hibernate and will not affect your program execution---------------------

Hibernate: insert into cost (Tax, Total, Price) values (?, ?, ?)

Looks like the program worked to me. The insert was a success. I cant see your database and tell if the information was actually commited though.

[kumari Jain]

The log4j warnings could possibly be removed if

1.Have a log4j.properties file
2.Make sure the above properties file is in the class path
