I have two Integer columns in the database (derby and db2). I need to divide them with each other inside a JPQL . Both columns being of type Integer return zero if remainder is a decimal number e.g 0.25 becomes 0 etc and understandably so since type is int. In SQL I could have this for example select CAST(column1 as decimal(6,2))/CAST(column2 as decimal(6,2))from Sometable; but what is JPQL equivalent . One option might be (I have not tried yet) is to have a @Transient method in the entity returning the Decimal type and doing this calculation there and pass that to JPQL but I would rather let

I need to display a read error when the source file is being used by other applications. For example : Source filename: test.txt Content: Test file. The above content is stored in the txt file and saved. The txt file is opened and is modified as below but not saved. Test file is modified. When i invoke the transfer now i should get a read error, instead the file gets transferred with the last saved content(Test file). What can i do to display a error message? This case was tested in unix and windows. 来源： https://stackoverflow.com/questions/5870083/to-display-a-read-error-when-the-source-file

Moreover, is this RPC a an custom implementation of Google , or is it a standard implementation ? 1) GWT RPC uses AJAX to allow Data transfer for GWT applications. 2) GWT RPC abstracts out

I need to setup a URL resource in WebSphere and is following this tutorial. However, the tutorial requires the modification of WebSphere's web.xml and ibm-web-bnd.xml using WebSphere Studio. I don't have a WebSphere Studio so I need to modify those files manually using a text editor. I tried to "search" for the 2 files but the "search results" are so many that I don't know which one is the right file. Where can I find the 2 files? Also what value do I need to set for the resource-ref 's id? I notice that WebSphere Studio doesn't have any text field for setting the resource-ref 's but it has a
