Handling BLOBs with CMP Beans

Hi,
is there a detailed example how to handle Blob's with CMP Beans?
I'm trying to store some images in a database (Oracle 9i) using CMP Beans and Oracle iAS 9.03 and jdk 1.4.
Thanks in advance
Jens

We are currently developing a How-To on this and will put this on OTN.
1) Code snippet from Bean Class:
public abstract byte[] getPicture();
public abstract void setPicture(byte[] newPicture);
public Long ejbCreate(Long empno, byte[] newPicture)
setEmpno(empno);
setPicture(newPicture);
return empno;
public void ejbPostCreate(Long empno, byte[] newPicture)
2) Mapping in the orion-ejb-jar.xml:
<entity-deployment name="EmployeePicture" data-source="jdbc/OracleDS" table="EMPPIC">
<primkey-mapping>
<cmp-field-mapping name="empno" persistence-name="EMPNO" persistence-type="NUMBER(8)"/>
</primkey-mapping>
<cmp-field-mapping name="empno" persistence-name="EMPNO" persistence-type="NUMBER(8)"/>
<cmp-field-mapping name="picture" persistence-name="PICTURE" persistence-type="BLOB(4000)"/>
</entity-deployment>
3) Create the client to create the bean:
Long empNo =(Long) Long.valueOf(request.getParameter("EmpNo"));
String fileName =request.getParameter("ImageFileName");
InputStream is = new BufferedInputStream(new FileInputStream(fileName));
int len;
// Initialize byte array
byte byteValue[] = new byte[2048000];
len = is.read(byteValue);
EmployeePictureLocal employeePicture = empHome.create(empNo , byteValue);
out.println("Picture of Emp#:"+empNo +" successfully Loaded into DB <br> <br>");
4) Code snippet to view the image :
Long empNo =(Long) Long.valueOf(request.getParameter("EmpNo"));
out.println("Picture of Emp#"+empNo);
EmployeePictureLocal emp = empHome.findByPrimaryKey(empNo);
response.setContentType("image/jpeg");
OutputStream os = null;
os = response.getOutputStream() ;
byte[] pic = emp.getPicture();
os.write(pic);
os.close();
os = null;
Let me know if this helps

Caching data with Entity Bean

Hello,
I am performing some tests concerning the benefit of caching data with Entity Bean.
Here is the case :
I have an Entity Bean with a business method getName() to retrieve a name field in the EJB.
I understand that in order to cach data, I have to set the NOT_SUPPORTED transaction attr for this method. In this way, when this method is called, the ejbReload() is not called and the data is retreived from the EJB ready instance (and not from the database).
Is it true and is it the good way to use the cach mechanism ?
Now if we consider that this instance is the only one in the ready stage, and it is never pooled (it seems so !), what about a modification of the database from a tier (or from an other EB instance)? The Entity Bean is not able to see this modification seence it does not call the ejbLoad method.
Is there a way to force an Entity Bean to be periodically polled in order to recover data from the data store when activated ?
Thanks in advance,
Thierry

No, This is wrong way of doing what you want. Most of the application servers provide various configuration settings for this. Eg. caching mechanism, interval on when to call ejbLoad and ejbStore, read only beans. You have to check the documentation for this.

Mapping Dates with CMP

Hello,
It seems that the old requirement to represent persistent Dates using a
database, low-level java.sql.Date CMP type instead of a classic,
business-level, java.util.Date is still valid. I can understand the
technical need for a java.sql.Date as a low-level issue but I don't
unterstand why we need to get it at the EJB level. It's sad to see that,
even at the EJB 2.0 Abstract Persistence Schema level, we still have to
jungle with java.sql.Dates.
Maybe someone can give me a good reason for that ?
Jérôme.

java.util.Date will be supported in the GA release.
Please only post message to one newsgroup only.

Error Occuring While Processing Data With DIAdem 8.1Exception EAccessViolation in module ntdll.dll at 000111DE. Access violation at address 7C9111DE in module 'ntdll.dll". Read address 37363430

Hello,
We are having an issue running Diadem 8.1 on a new HP XW 9400 with Windows XP SP2. 3 errors have been occuring with frequent crashes, they are:
1) "1Exception EAccessViolation in module ntdll.dll at 000111DE. Access violation at address 7C9111DE in module 'ntdll.dll". Read address 37363430.
2) The instruction at "0x7c9111de" referenced memory at "0x352e302d". The memory could not be "read".
3) ---Error--- DIAdem

We are using the same scripts and version 8.1 on a variety of Dell desktop computers (W2K and XP SP2) without any issue, looking for suggestions as this affects no other software on the HP XW 9400 other than DIAdem. Appreciate any suggestions.

Christian,
I will answer your questions in the text below. Thanks for your help.
Hi swillh,
I also would like to help you.
Unfortunately, The reported access violation in the central Windows ntdll.dll is very unspecific.
May be the following questions will help you to provide me more info.
1. You mentioned that the aut's and - I think - also the accessed text file reside on a server.
Is there a stable network connection?
The server can sometimes be a little slow but the connection is good. This computer is using the same connection that the prior computer utilized without issue.
Are the files accessed by multiple clients simultaneously?
It is possible that more than one computer can be accessing the same file, but again, this has never been an issue. We are reading the files only, not writing to them.
The processing routines we are running have used for over 5 years without any issues until adding this computer.
Is the text file read by one client while another client is writing the same file?
No, files are "read only"
2. Have you already tested opening the file with the FileOpen command before calling FR?
Yes
Do you see any chance to convert the aut to a vbs file? This gives you more alternatives in accessing text files.
3. What do you mean with "processing ATD's with 30 or more channels of data"? Where is the relation between ATD files and data channels?
Processing Crash Dummy data with file sets low in channel count (15 channels) result in successful processing without any crashes or access errors. When processing dummies with more than 20 channels we sometimes encounter these issues. The higher channel count may be the only common factor I can find in these faults.

Partial queries with CMP beans

Hi,
I have a custom finder method called findBySurname which takes in a string. I've set up the partial query to read: surname=$1 (where surname is the cmp field mapped to the table column). I've checked the orion-ejb-jar.xml file and the query has been inserted. However, when I run the sample client, I get a resultset that contains all the records in the table! I've got similar finder methods on 3 CMP beans and they all do the same thing. Is this a bug in the Release Candidate 2 version of Jdeveloper (which I'm using) or am I missing something?
Thanks in advance,
Gillian

Problem with CMP bean and MySQL: please help me!!!

Hi,
I am using J2EE Sun server 1.3 and Mysql 4.0 database with its MySQL Connector/J 3.0.
The driver connection to the database is fine since "Generate Default SQL" in deploytool gives "SQL generation complete".
However, I can't have a simple row with one text field called test being created in my mysql table called test.
Of course , the mysql server is started and the test table set for use.
Here is my code (I try to access my database from a servlet using a CMP Entity bean):
try{
Context initial = new InitialContext();
Object objref = initial.lookup(EntityHome.JNDI_NAME);
EntityHome home = (EntityHome)PortableRemoteObject.narrow(objref,EntityHome.class);
Entity test= home.create("zob");
/*EntityHome home = (EntityHome)PortableRemoteObject.narrow(objref,EntityHome.class);
catch (Exception ex){                                                                out.println("exception message : " + ex.getMessage()+"</body></html>");}
I get the following exception message :
RemoteException occurred in server thread; nested exception is: java.rmi.RemoteException: nested exception is: java.sql.SQLException: Syntax error or access violation, message from server: "You have an error in your SQL syntax. Check the manual that corresponds to your MySQL server version for the right syntax to use near '"EntityCMPTable" WHERE "test" = 'zob'' at line 1"; nested exception is: java.sql.SQLException: Syntax error or access violation, message from server: "You have an error in your SQL syntax.

Problem with CMP BEAN ON SUN JAVA APPLICATION SERVER 1.3.1

I am trying to deploy an entity bean with container managed persistence on sun java app. server 1.3.1. When I go for Deploy, the error 'SQL code not generated for following beans' is comming, when verified with verifier tool, the error shown is 'transaction attributes are not specified' , What should be the problem ?

Which appserver are you using exactly? the J2EE 1.3.1 RI, SJAS 7.0, SJSAS 7.1....etc
You need to make sure for that you have specified the correct deployment attributes for your CMP methods. You can pull the ear/jar into deploytool and review it there

you need to write the code for adding the receipents, subject and adding this "attachment " as an attachment to the mail.
Hope this will helps to you....,

Error:UNCAUGHT_EXCEPTION while loading data with exception CX_RSR_X_MESSAG

Hi,
Ours is a fresh installation..
When i am loading for the first time till PSA it is successful..
As HR data sources are 3.5 datasources, i am loading cube via infopackage..
When i start the load to cube it is giving me dump with exception CX_RSR_X_MESSAG.
i checked note 615389 which talks about "buffering of number range object BIM9999998". the 0REQID is not buffered, but it does not throw any error msg in RSRV to correct the error..
and one more note 1157796 which talks about patches with version BI 7.0.
Now we are in BI 730 with heighest level 0005.
Not sure how to solve this error
Any ideas?
