Hibernate bug using Oracle?

- by Lothar

Hello, I've got the problem, that I use a property in the persistence.xml which forces Hibernate to look only for tables in the given schema. <property name="hibernate.default_schema" value="FOO"/> Because we are using now 4 different schemas the actual solution is to generate 4 war files with a modified persistence.xml. That not very elegant. Does anybody know, how I can configure the schema with a property or by manipulation the JDBC connection string? I'm using Oracle 10g, 10_2_3 Patch. Thanks a lot.

How to read a column in a tab-delimited Excel file in C#?

- by janejanejane

I have some data of an excel file below. At first, I figured that reading from the file could be done using the Excel Library then using an OLEDB connection. I managed to get the DocumentNo column data with the OLEDB approach. However, when the excel file is closed, I am unable to do the operation because it gives an error that "External table is not in the expected format." How can I read from the file even if it is closed? 10/4/2010 Paid Documents for Document Tracking - Customer 1 Paid Documents for Document Tracking - Customer CoCd Customer Trans.type SG Clearing Clrng doc.

- by DixieFlatline

Hello! I use apache 4 java libs for http get connections. I get all cookies from 2 other pages. But one other webpage contains google analytics cookies(utma,utmz...) and classic session id cookie (checked with firebug). When i try to get the cookies i only get sesson id cookie. Is there any trick to get all the cookies from java in connection with google analytics? If i want to make a http post, it seems that i have to send google analytics cookies too. I can copy my code if somebody wants, but it works on other pages(for printing cookies). Thank you

hosting acounts for large uploads

- by Phil Jackson

Hi, im wondering if anyone knows of any host providers ( uk preferably ) that deals mostly with accepting large file uploads. Most hosts only let you push something like 1.5mb ( thats taking into account the connection and the max execution time ). What i am looking for is a host specificaly for storing files on. I was going to create an upload script onto my application which posted the file to the external host and then return back ( using headers so the user doen't even know they have left ). Does anyone know of a host for this?

When to use memberEnd and when navigableOwnedEnd in an UML class diagram?

- by Ivan

I've download a trial of Altova UModel and am starting using UML. As a practical beginning I am modelling a personal information manager application, which includes a web bookmark managing. A Bookmark can belong to many (or no) Tags at once and a Tag can contain many (or no if all the bookmarks it contained were deleted) bookmarks. The relation has to be both-way navigable - a user has to be able to see all Bookmarks with a particular Tags ans all Tags of a Bookmark. What is the correct UML relation between Bookmark and Tag classes? As far as I understand UML now, it is an Association (not an Aggregation). But for a 2-way navigable many-to-many relation I can specify ends roles as "memberEnd" or "when navigableOwnedEnd", graphically the connection looks the same in both cases (an arrow) (which as I understand means navigability) but a property appears in the class box in case only when "memberEnd" is used. How should I specif it in the model If I mean both-way navigable many-to-many relation there?

Excel Spreadsheet - Best way to perform an Oracle Query on a cell

- by Jamie

Hi there, I have an Excel Spreadsheeet. There is a cell containing a concatenated name and surname (don't ask why), for example: Cell A2 BLOGGSJOE On this cell, I would like to run the following SQL and output it to cell A3, A4 and A5 SELECT i.id, i.forename, i.surname FROM individual i WHERE UPPER(REPLACE('" & A2 & "', ' ', '')) = UPPER(REPLACE(i.surname|| i.forename, ' ', '')) AND NVL(i.ind_efface, 'N') = 'N' Any idea how I could perform an oracle query on each cell and return the result? I have enabled an oracle datasource connection in Excel, just not sure what to do now. Is this a stupid approach, and can you recommend a better more proficient way? Thanks muchly! I lack the necessary experience in this type of thing! :-) EDIT: I am aware that I could just write a simple ruby/php/python/whatever script to loop through the excel spreadsheet (or csv file), and then perform the query etc. but i thought there might be a quick way in excel itself.

limit of connections with database and number of java threads in an application

- by Jyoti

Hi, I am working to develop a JMS application(stand alone multithreaded java application) which can receive 100 messages at a time , they need to be processed and database procedures need to be called for inserting/updating data. Procedures are very heavy as validations are also performed in them. Each procedure is taking about 30 to 50 seconds of time to execute and they are capable to run concurrently. My concern is to execute 100 procedures for all 100 messages and also send reply within time limit of 90 seconds by jms application. No application server to be used(requirement) and database is Teradata (RDBMS) I am using connection pool and thread pool in java code and testing code with 90 connections. Question is : (1) What should be the limit on number of connections with database at a time? (2) How many threads at a time are recommended? Thanks, Jyoti

Basic Client-Server Design for persistent connections?

- by cam

Here's as far as I understand it: Client & Server make connection Client sends server data Server interprets data, sends client data So on, and so forth, until client sends disconnect signal. I'm just wondering about implementation. Step 2 and 3 are confusing to me, maybe I'm over-complicating it. Is there anymore to interpreting the data than a giant switch statement? Any good books on client/server design? Specifically talking about multithreaded servers, scalability, and message design (byte 1 = header info, byte 2 = blah blah, etc)? Specifically geared towards C++.

"derivative work" and the consumption of web services

- by yodaj007

From the Wowhead Terms of Service: "Intellectual Property Rights The Service and any necessary software used in connection with the Service ("Software") contain proprietary and confidential information that is protected by applicable intellectual property and other laws. You agree not to modify, rent, lease, loan, sell, distribute or create derivative works based on the Service or the Software, in whole or in part." Does this mean that I can't write a program to consume a web service being published by the writers of this TOS? I find it kind of scary that I even have to ask this question. The wikipedia article on "derivative works" isn't very conclusive.

ASP Classic Named Parameter in Paramaterized Query: Must declare the scalar variable

I'm trying to write a parameterized query in ASP Classic, and it's starting to feel like i'm beating my head against a wall. I'm getting the following error: Must declare the scalar variable "@something". I would swear that is what the hello line does, but maybe i'm missing something... <% OPTION EXPLICIT %>  <% Response.Buffer=false dim conn,connectionString,cmd,sql,rs,parm connectionString = "Provider=SQLOLEDB.1;Integrated Security=SSPI;Data Source=.\sqlexpress;Initial Catalog=stuff" set conn = server.CreateObject("adodb.connection") conn.Open(connectionString) set cmd = server.CreateObject("adodb.command") set cmd.ActiveConnection = conn cmd.CommandType = adCmdText cmd.CommandText = "select @something" cmd.NamedParameters = true cmd.Prepared = true set parm = cmd.CreateParameter("@something",advarchar,adParamInput,255,"Hello") call cmd.Parameters.append(parm) set rs = cmd.Execute if not rs.eof then Response.Write rs(0) end if %>

What Use are Threads Outside of Parallel Problems on MultiCore Systesm?

- by Robert S. Barnes

Threads make the design, implementation and debugging of a program significantly more difficult. Yet many people seem to think that every task in a program that can be threaded should be threaded, even on a single core system. I can understand threading something like an MPEG2 decoder that's going to run on a multicore cpu ( which I've done ), but what can justify the significant development costs threading entails when you're talking about a single core system or even a multicore system if your task doesn't gain significant performance from a parallel implementation? Or more succinctly, what kinds of non-performance related problems justify threading? Edit Well I just ran across one instance that's not CPU limited but threads make a big difference: TCP, HTTP and the Multi-Threading Sweet Spot Multiple threads are pretty useful when trying to max out your bandwidth to another peer over a high latency network connection. Non-blocking I/O would use significantly less local CPU resources, but would be much more difficult to design and implement.

Weblogic Error - Method not supported : Statement.cancel

- by manetic

I am running an application on Weblogic 9.2 MP3, currently having problem with connection pool. ERROR - UserBean retrieving user record. weblogic.jdbc.extensions.PoolLimitSQLException: weblogic.common.resourcepool.ResourceLimitException: No resources currently available in pool MyApp Data Source to allocate to applications, please increase the size of the pool and retry.. I also kept getting below error message, saying "Method not supported : Statement.cancel()" which I think it is the cause to the error above. <Error> <JDBC> <BEA-001131> <Received an exception when closing a cached statement for the pool "MyApp Data Source": java.sql.SQLException: Method not supported : Statement.cancel()..> I went through the app source code, this method didn't seem to be used by the app at all. Just though it might be something to do with weblogic itself. Anyone have any idea to fix this error?

Python subprocess.Popen hangs in 'for l in p.stdout' until p terminates, why?

- by Albert

I have that code: #!/usr/bin/python -u localport = 9876 import sys, re, os from subprocess import * tun = Popen(["./newtunnel", "22", str(localport)], stdout=PIPE, stderr=STDOUT) print "** Started tunnel, waiting to be ready ..." for l in tun.stdout: sys.stdout.write(l) if re.search("Waiting for connection", l): print "** Ready for SSH !" break The "./newtunnel" will not exit, it will constantly output more and more data to stdout. However, that code will not give any output and just keeps waiting in the tun.stdout. When I kill the newtunnel process externally, it flushes all the data to tun.stdout. So it seems that I can't get any data from the tun.stdout while it is still running. Why is that? How can I get the information? Note that the default bufsize for Popen is 0 (unbuffered). I can also specify bufsize=0 but that doesn't change anything.

How do you get Windows Mobile Device Center to detect a Windows Phone 7 Series emulator?

- by sweeney

Hello, I'm running some tests and need to be able to get Windows Phone 7 Series emulator synced with an exchange account or local Outlook account via the Device Center. I'm using the unlocked version of the emulator so that i actually have a reasonable set of software on the phone to work with. When the emulator launches i expect the Device Center to detect it and start syncing (or prompt me for settings). This does not happen. I've tried adjusting the Connection Settings (COM2 and DMA) in the Device Center with no luck. Is this possible? Has anyone done it? Thanks in advance!

Mysqli prepared insert statements always returning false

- by user1754679

I'm writing prepared statements that are supposed to insert data into a table, on a database that's been pre-selected in the variable $GLOBALS['mysqli']. The connection has been tested, and that's not the problem I'm having. I'm only running into trouble whenever my prepared statement involves INSERT INTO. I know the tablename, and field names are correct, but $stmt is ALWAYS false. What gives? $stmt = $GLOBALS['mysqli']->prepare("INSERT INTO audit_RefreshCount (user, count, lastrefresh) values (?,?,?)"); if ($stmt == TRUE) { $stmt->bindParam('ssi', $_SESSION['username'], '0', time()); //$stmt->bind_Param('ssi', $_SESSION['username'], '0', time()); // Also doesn't work. $stmt->execute(); }

Using T-Sql, how can I insert from one table on a remote server into another table on my local server?

- by GenericTypeTea

Given the remote server 'Production' (currently accessible via an IP) and the local database 'Development', how can I run an INSERT into 'Development' from 'Production' using T-SQL? I'm using MS SQL 2005 and the table structures are a lot different between the two databases hence the need for me to manually write some migration scripts. UPDATE: T-SQL really isn't my bag. I've tried the following (not knowing what I'm doing): EXEC sp_addlinkedserver @server = N'20.0.0.1\SQLEXPRESS', @srvproduct=N'SQL Server' ; GO EXEC sp_addlinkedsrvlogin '20.0.0.1\SQLEXPRESS', 'false', 'Domain\Administrator', 'sa', 'saPassword' SELECT * FROM [20.0.0.1\SQLEXPRESS].[DatabaseName].[dbo].[Table] And I get the error: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

Win32 Thread Exits Unexpectedly

- by sahs

Hello, I'm writing a C++ application. I realized that one of my worker threads may terminate unexpectedly. The (VS 2005) debug log says: The thread 'Win32 Thread' (0x5d98) has exited with code -858993460 (0xcccccccc). I surrounded all the worker thread code with a try/catch block. So, if the reason was an exception, I would catch it. But I can't: try{ ... Connection* conn = connectionPool->getConnection(); // unexpected exit occurs here ... } catch(exception& e) { ... } I have ten threads running concurrently, and only one of them gets crashed after some time, while the others continue running (and getting new [OCCI] connections). Is there an exception type that is not caught by "exception"? Or what do I not know about threads/exceptions? Thanks.

getcwd for current location based on ftp account permission

- by John Doe

Hello. I'm trying to make a small script that's changing the permission for specific file using a ftp connection. My problem is the absolute path. I have a ftp account wich land on the script directory (/script/). If i'm using getcwd, it will return the whole path (/home/user/public_html/script) but i need only the difference between the full path and the current path (getcwd path: /home/user/public_html/script/ ftp landing path: /script). So, how can i use getcwd to get the current directory for a ftp account? For example, if the user is landing in public_html, the path to the script will be /script/, or if he is landing inside /user, the path will be /public_html/script. Thanks
