tomcat6 - tomcat: how can i place parameters in web.xml and fetch them in my application? -


I want to store DB connection information in the application web.xml file and want to bring it into the application.

Thank you!

2) In your web.xml Link to your resource pool

P>

eg (Tomcat 5.5 and above).

I have an example_des (data source) in the connection pool, and here I your web.xml 

  & lt; resource ref & gt; & Lt; description & gt; database connection, for example & lt; / description & gt; & LT; race-referee-name & gt; JDBC / Example_DS & lt; / race-referee-name & gt; & lt; Press Type & gt; javax.sql.DataSource & lt; / Race Type & to gt; & LT; Race Writing & gt; container & lt; / race Writing & gt; & LT; Race sharing-scope and shared gt; the qualified & lt; / race sharing the room & gt; & Lt; / resource ref & gt;

the context.xml (meta created found in -aianaf folder) coincides with my resources. still using Tomk. 

  & lt; resource name = "jdbc / example_ds" auth = "container" types = "Javax.sql.DataSource" maxActive = "100" maxIdle = "30" maxwait = "10000" username = "YOURUSERNAMEHERE" password = "YOURPASSWORDHERE" driverClassName = "com.mysql.jdbc.Driver" url = "JDBC: mysql: // localhost: 3306 / DATABASEHERE autoReconnect = true" removeAbandoned = "true" RemoveAbandonedTimeout = "60" log expired = "true" testonbase = "true" verification = "selection1" />

Obviously, you can see that I am using MySQL here.

& lt; Resources / & gt; allows you to create a connection pool (in Tomkat)

In JBoss ....

1) a Example_DS.xml file where for example your data source Name is

example

then the user & lt; Resource Ref & gt; that I left earlier in Jboss to map it to my DS. Deploy your DS.xml file to / Server / Default / Deployed / Folder and restart JBoss.

Once you have completed, you can call it using Java in context.

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
