Problems with storing EJB Remote in session and retrieving.

We store EJB remote object in session and differnt clients retrieve it from session
before making a business method call. This seems to work in most cases but some
times it gives the exception attached. This happens only in a clustered environment.
What has been observed is that if we put the remote object inside a hashtable
which in-turn is stored in session retrieval from hashtable does not give this
problem.
Any suggestion / solution would be greatly appreciated.

Rajesh

Hello Rajesh,
Thanks for your sugggestion. Rajesh Karuvat and myself are working on the same
project.
I want to know if there is any specific patch for this problem for weblogic 6.1
sp3.
The reason we can not just try Weblogic sp4 is that we are using epicentric 4.0
that is cvertified with weblogic 6.1 sp3 and not sp4.
I have also opened a case with bea about it. I would reaaly appretiate if you
can check the detials about it. The case number is 376228.
Please do revert back.
Thanks,
Shilpa

Problem with Stored Procedure exection in Sender and Receiver side of JDBC

Hi All,
I am facing problem while executing Stored Procedures using sender and receiver sides of JDBC adapter.
Here is my SP in Oracle DB :
PROCEDURE EMP
( ID IN VARCHAR2,NAME IN VARCHAR2,PROCESSED IN VARCHAR2 ) AS
BEGIN
   INSERT INTO EMPLOYEE VALUES (ID, NAME, PROCESSED);COMMIT;END EMP;
Now I want to execute this SP using sender JDBC channel and receiver JDBC channel.
Can anyone please help me executing this SP?
Regards,
Soorya

Hi Soorya,
The receiver Data type should be like this:
<StatementName>
<storedProcedureName action=u201D EXECUTEu201D>
    <table>realStoredProcedureeName</table>
<param1 [isInput=u201Dtrueu201D] [isOutput=true] type=SQLDatatype>val1</param1>
</storedProcedureName >
</StatementName>
Check the link http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
Which DB are you using?? The sender structure will be like
<resultset>
<row>
<field1></field1>
<field2></field2>
<field3></ field3>
</row>
</resultset>
Search SDN you will get lot of examples

Problem with storing and retriving a different langauge font in mysql

hi,
i have problem with storing and retriving a different character set in
mysql database ( for example storing kannada font text in database)
it simply store what ever typed in JTextField in database in the
formate ??????????? and it showing ???????? .
please what can i do this problem.
thanks
daya

MySQL does not know about what type of Font you use or store. that is applicatioon specific. All it knows is the character set that you are storing and the data type and data. THere are something you should know when working with database and Java:
1. make sure you know what character set is used for the database table.
2. make sure you know what character set is used by Java (default to UTF-8 ..
sort off - there are few character that it cannot save). You can enforce the
character set being sent to the database by the String's getBytes(String charsetName) method.
3. make sure the application you use to view the table use the correct character set
if it use a different character set, then any character that it does not recogized
will be replaced with a quetion mark '?'....eventhough the data is correct.

I have a problem with the synchronisation of my iPhone and iPad with Outlook 2007 on my 64-bit Windows 7 PC. For several years, I have had no problems with the synchronisation by cord connection and iTunes between these programmes. However, a few months

I have a problem with the synchronisation of my iPhone and iPad with Outlook 2007 on my 64-bit Windows 7 PC. For several years,
I have had no problems with the synchronisation by cord connection and iTunes between these programmes. However, a few months ago I decided to use Mobile Me. However, there were problems with duplication of calendars and then “rogue events” – which could not be deleted – even if deleted on Outlook and on the iPhone (or both at the same time) – they would just reappear after the next synchronisation. All other synchronisation areas (eg Contacts, Notes etc) work fine.
I have looked for help through the Apple Support Community and tried many things. I have repaired my Outlook. I have repaired my .pst file in Windows. I have re-installed the latest version of iTunes on my PC. I have re-installed the firmware on my iPhone. I have tried many permutations on my iPhone. I have closed down all Mobile Me functions on the iPhone. I have spent upwards of 24 hours trying to solve this problem.
What am I left with? Outlook works seamlessly on my PC. My iPhone calendar now has no events from my calendar, but does not synchronise through iTunes. Nor does it send events initiated on the iPhone to the Outlook. I am at the point of abandoning iPhones and iPads altogether. I need to have a properly synchronising calendar on my phone. Do you have any suggestions?

In the control panel goto the "Lenovo - Power Manager" and click the battery tab, there is a maintenance button in there that will let you change the charging profile for your battery. (from memory, so exact wording may be off)
The lower the numbers you use there, the longer the battery *should* last. These batteries degrade faster at higher charge levels, however storing them at too low of levels is also not good for them... I've read that 40% is optimal, but just not realistic if you use your computer.

Problem with the fiells MEINS(PO Unit ) and MENGE(Quantity) .

Hi experts
I am having problem with the fiells MEINS(PO Unit ) and MENGE(Quantity) of the datasource 2lis_02_acc .
I have created custom cube and have mapped the fiels MEINS to infoobject 0PO_UNIT and MENGE(Quantity) to infoobject 0CPQUAOU.
Now the data is successfully loaded in the cube but the values of the above 2 fields are getting changed.
In r3 the value for MEINS is "AU","EA" , "H" etc but this field value is getting converted to "LE" in the cube and also the field MENGE(Quantity
) in r3 is for example "1" it is getting converted to 3 in the cube. do u have any idea what is the problem.
The rule type is direct assingment and there is no routine .
Any clues.
Thank you.

Hmm, your system should consider the alternative UOM maintain in the material master.
Each material in SAP has its standard, base unit of measure (stored in MARA-MEINS). To allow using alternative units, those can be maintained per material in table MARM. So, assuming the Base UoM is only considered (for LE), it converts material quantity from one unit to another, most likely from alternative units to the base one. So, changing that settings must solve. http://goo.gl/JuZlm
Alternative steps:
1.Goto MM42 (Assuming there's no BAPI req?)
2. change po unit from basic unit to other -> save OK
3. change po unit from other to basic unit -> save OK
Also, MD63 shows all data in the base unit of measure.
If you want to explore basic steps, goto RSD1 > Additional > Alternative UoM.

URGENT ! JDEV 10.1.2 Problem with data control generated from session bean

I got a problem with data control generated from session bean which return a collection of data transfer object.
The dto's seem to be correct. The session bean load correctly the data into and the object's are plenty of data. Using the console to display the dto content is ok.
When generating a data control from this session bean and associate the dto included in the collection only the first object level and one-to-one dto object are correctly setted in the data control. Object that represent collection into the dto (one-to-many foreign key) are setted as collection with an iterator but the structure of the object is not setted. I don't know how to associate this second level of collection with the dto bean class to obtain the attributes definition.
I created a case with hr schema like the hrApp demo application in the tutorial with departments and employees table. I got the same problem.
Is it a bug ?
It exists a workaround to force the data control to understand the collection data structure ?
Help is welcome ! this is urgent !!!

we found the problem by assigning the child dto bean class to the node representing the iterator in the xml file corresponding to the master dto.

Is there a problem with Entity EJBs on 8.1.7?

Oracle 8.1.7 on Solaris 7:
Bean Managed persistence:
TX Attribute - Required:
UserTransaction bound into JNDI:
I have tried numerous times and numerous ways to get my Entity beans working. Ejbs that represent tables with 3 columns work fine, but another EJB with 15 columns doesn't - ejbCreate, ejbFindByPrimaryKey work fine, but whenever make some changes and subsequently commit, ejbStore doesn't execute, I even had my client sleep for 15 secs, but still nothing. I know there is a problem with deploying EJBs using JDeveloper 3.2, but I have deployed all these EJBs using deployejb command line tool on the server itself!
We are right now trying to find out whether Oracle is our right choice for EJBs, any input is highly appreciated.
Thanks in Advance.
Ashish.

Upon further investigation this is what I have found:
1. Created another EJB for the 15 column table, but this time represented just 3 of its columns - so I have 3 instance variables in the Bean, and a getter/setter method for each except a setter for the primary key.
2. Undoubtedly it worked fine.
3. Increased the number of columns to 4 and GUESS WHAT, upon calling setXXX for the newly added setter method and committing, it started failing, the value just wouldn't change in the DB. But when I call all the setXXX methods, it works just fine, I finally narrowed it down to just 1 setXXX method, if I use this method with any other setXXX methods, all the values get updated, otherwise none of them get updated.
CLEARER PICTURE:
Supposing I have the following instance variables in the Bean:
String id;
String dt;
String vol;
String price;
String beg_day;
String end_day;
and the following get/set methods
String getId()
String getDt()
String setDt()
String getVol()
String setVol()
String getPrice()
String setPrice()
String getBeg_day()
String setBeg_day()
String getEnd_day()
String setEnd_day()
Now if I do the following:
HomeInterface hm = ...JNDI lookup
UserTransaction ut = ...JNDI lookup
ut.begin();
RemoteInterface rm = hm.findByPrimaryKey("1");
rm.setBeg_day("01-DEC-00");
ut.commit();
nothing happens, the date in the underlying table is still the same, BUT.....
if I do this:
ut.begin();
rm = hm.findByPrimaryKey("1");
rm.setDt("01-DEC-00");
rm.setBeg_day("01-DEC-00");
ut.commit();
IT WORKS..... using setDt() with any other method works for that setXXX method also...
Anybody experience this at all.....
Thanks in advance for your help.
Ashish.
PS: setDt() is the last method in the stBean.java file with the maximum __method_index, does that make any difference??

Somewhere at either Macworld or here I learned that DVDSP 2, DVDSP 3 and now DVDSP 4 "internally" are major re-writes.
Support for HD among a few other items along with QT 7 which comes with Tiger means sincerely that one set of applications/OS is not going to be stable.
Personally I think of all the issues possible its DVDSP vs QT.
Unless you move to DVDSP v4 the alternative is to wipe the disk and go back to Jaguar (10.2) or perhaps Panther but avoid upgrading QT beyond 6. I advocate wiping the disk because I'n not sure an archive and install to down shift to an earlier version of the OS is possible. If it is I'd still worry about mis-matched files in all sorts of locations.

Hi
I've a big problem with adobe acrobat reader XI pro and I hope you can help me.
The problem is; when I past copied text from some pdf books (not all of them) it past symbols only! wherever I past it! and even if I coped that text from another pdf reader (adobe pdf reader, internet browsers, ...etc.).
This problem started to happen since yesterday when I installed adobe acrobat reader XI pro to try it before I buy it, and before that when I was using the free adobe pdf reader I was totally able to copy any text from any pdf and past it anywhere with nothing wrong.
What can I do?
thank you a lot.

There is no product called Adobe Acrobat Reader Pro. There is
- Adobe Acrobat Pro ($$)
- Adobe Reader (free)
Which do you have? And are you a programmer?

wen6275,
It looks like you're actually using a camera or phone to take a photo of your monitor.
That's not what is commonly known as a "screen shot".
It looks like you're on a Mac. Hitting Command+Shift+3 places a capture of the contents of your entire monitor on your Desktop; hitting Command+Shift+4 will give you a cross-hairs cursor for you to select just the portion you want to capture.
I'm mentioning this because I fear I'm not construing your original post correctly when you type "I am working with a large files [sic], currently it has 149 layers, all of which are high resolution photographs", so I'm wondering if there's some similar use of your own idiosyncratic nomenclature in your description of your troublesome file.
Perhaps I'm just having a major senior moment myself, but I'm utterly unable to imagine such a file. Would you mind elaborating?
