Where to store "global variable" for a web application

There are some "global" variables in my portal web application. e.g. email server
name, admin email address etc. Will web.xml context-param a good place to store these
kind of information?
If so, how do I retrieve it back from a java class? It is easy in a jsp file: appalication.getAttribute(),
but how about a pipeline component or input processor which are all java file.
Please help!
Thank you very much

I still believe that the information like connectivity parameters to remote
servers in the distributed environments would be best stored in the JNDI
tree. I agree, that it is not a "general storage area", but I am not talking
about storing application run-time data either.
In the clustered environments it would provide additional benefits of
centralizing this kind information across the cluster.

JNDI is not a general-purpose storage area, although you could bind data
in a JNDI tree. A better (and simpler) way is to store them as context
parameters. You could read the initial values for these variables from a
servlet init parameters.

I would advise to put you global variable in JNDI tree.
You can use jndi.properties file to store name-value pairs, which will
get
loaded into jndi tree at the server startup. Just put this file in your
application class path.
The other method would be to code a startup class to store the global
variable in the jndi tree.

How to store global values for the whole application to use ?

Hi,
In our application, we have global values that is store in a parameter table, I want only to query it once, and it will be used every where from the whole application.
e.g :
I have general parameter tables that store :
% Tax
Current Period
etc..
Then these values will be used in our business rules in the whole application.
How can I do that in ADF BC ?
Thank you,

I would go ahead and create a transient VO with an attribute called "userLanguage" and store the value at the initialization step.
We generally call this type of VO as PVO which is a transient VO and contains only 1 record at any point of time. Keep this VO inside the RootAM and you can write a static util method as below..
public static String getUserLanguageFromPVO()
PVOImpl pvo = (PVOImpl)am.findViewObject("MyPVO");
if(pvo != null)
Row row = pvo.first(); //Always returns the one record
return (row == null ? null :
(String)row.getAttribute("UserLanguage"));
return null;
}

Where can I store global variables.

Hi All,
Where can I store global variables. Requirement is, ability to modify and add to the list of global variables. Any modification should be reflected dynamically. One way to do is to store in Entity Beans. I thought storing in DataBase will impact performance. Any advice.
Appreciate any help.

----- form1.#subform[0]::initialize: - (FormCalc, client) ------------------------------------------
(I have assumed that this is where I would store Global variables)
At this stage, the global variables cannot be accessed with the configuration above. The only was I can get this to work is to cut and paste the global vairables into each form1.#subform[0] item, which of course defeats the purpose of global variables! I plan to have many more items so would not want to duplicate the global variables for all of them!
Can somebody show me how to do this?
Any help is very much appreciated!
Thanks

Message was edited by: stanbridgej - colors and or fonts won't save. Have bolded my question to make code (non-bolded) easier to read (I hope).

Hi MorisTM,
Thanks for the reply!
Yes, I saw that option (I should have mentioned I already knew about it), but was wondering if there is a way I can do this via code.
There are two reason I want to be able to do it via code (only one of which may be valid):
1) I can automatically generate my pricing code form another inhouse app.
2) I am hoping that later on once I get this working I will be able take it a step further and get the data directly from a MySQL database!
Cheers though!
Any other suggestions?

Use global Variable for Formatstring

Hello
I wanna use a global variable for a format string. see picture. But I don't work.
Can anybody give me an idea, why it won't work?
Thanks a lot!!!
Attachments:
GlobalVariable.jpg ‏61 KB

As others said, the problem is not the global.
See attached a picture of how to do what you want. Since the Format String is unknown at edit time, you must provide the types to all inputs that are not DBL.
From your example, the while loop has been coded exactly like a for loop. It can be replaced with a for loop with auto-indexing, unless you really want the local variable to be update at each iteration every 50 ms. This delay is not necessary unless the computed array is huge and you want to leave some CPU time to other code in your application. Even then you can enter a delay of 0ms to force to swap to other tasks.
I don't know what your INT>BOOL VI does but using Scan from String you can read a number directly into a boolean. The number i
s rounded to an unsigned integer and 0 is False and >0 is True.
For example you scan a string for a boolean with format string %d.
"0" --> False
"24" --> True
"-18" -- False (coerced to unsigned = 0)
You scan a string for a boolean with format string %f:
Negative number up to "0.5" --> False (coerced and rounded to 0)
Number greater that 0.5 --> True

Configuring the authentication scheme for a web application

Hi all,
We have a requirement to configure the authentication scheme for a web application where some set of users should access the application using basic LDAP (userid/password) authentication and some using digital certificate authentication.
Since the deployment descriptor (web.xml) allows only one directive for auth-method in logic-config, we want to know if there is any other way to achieve this requirement. We are thinking of a custom login module approach. But we are not able to figure out how to configure the auth-method at runtime from the login servlet.
Please let us know if there is any other approach to achieve this.
I will be thankful if any body shares any specific solution to this issue.

This forum is probably not the correct one to ask in. It's more related to the web container than Java Programming.

Migrating to Sharepoint 2013 from 2010 - Can you use the same URL for the Web Application without affecting the 2010 environment?

Hi,
I am currently trying to migrate our SharePoint 2010 environment to SharePoint 2013. The first thing I'm doing is creating a 2013 development environment to verify that this migration goes smoothly. I'm also doing this so that we will have a testing environment
after the upgrade to 2013 is complete.
So here is my question: I have a 3 tier farm including; 1 app server, 1 wfe, and 1 sql server. I have made a copy of our SharePoint 2010 database and installed that on our sql server 2012 sever (This new environment is on 3 completely separate servers from
our 2010 environment). I have also installed the prereqs and configured SharePoint 2013 on the App server and wfe servers, as well as configuring the necessary service applications (I have created a completely new 2013 database where I will migrate my 2010
database content when I'm ready).
I am now at the point where I need to create a new web application on the 2013 app server, where I will be migrating the copied 2010 database. (Also note that we have a 2010 development site called https://[email protected])
When I go to create a new web application in our 2013 dev environment, can I use the same url (https://[email protected]) to create this web app, or will this screw up our current 2010 dev environment?
I'm new to SharePoint migrations, so I apologize if this is a stupid question.
Thanks in advance for any insight you can share on this!
Boe Barlage

So, what you are recommending is that before I create a web application in my new 2013 environment, I need go into my hosts file on my 2013 app server and alter it to point to my 2013 wfe.
Then after I do that, then I can create my new web application on my 2013 app server with the same url as my 2010 testing environment
(https://[email protected]).
Then after that I should be able to access my new sharepoint 2013 environment at the same URL (https://[email protected])?
I must be missing something.
In your first reply, you told me to alter the host file on my 2010 app server and point it to my 2010
wfe (I guess I thought it probably already is). You also told me to alter the host file on my 2013 app server and point it to my 2013 wfe.
so I am confused on after I do this, what url would I access my 2010 test environment, and what url would
I access my 2013 test environment?
I am fine with having my test environment as a different URL until I am totally ready to roll everything over and kill the 2010 site. But I want to make sure that when I migrate my database, none of the site links are broken.
I also want to make sure that if I proceed this way, I want to be sure that I will be able to modify the URL to what my 2010 environment is (without a lot of headaches) when I am ready to kill the 2010 site.
Thanks again for your help, it's much appreciated!

SharePoint 2013 Central Admin says port 80 for three web applications, but IIS says they have different ports

Hello,
I have three web applications on a SharePoint 2013 servers. In Central Administrators on the Application Management page where it lists all of the web applications, it shows Port 80 being used 2 3 sites. When I go to IIS, 2 of the 3 are using
different ports, 81 and 82. So, only one site IIS says is using port 80. Why is this? The host file has no entries in it. Where these web applications extended?
Thanks,
Paul
Paul

Hi Paul,
From the URL of the web application in Central Administration in the image, you have configured the Alternate Access Mapping for the web applications.
And the URL configured is by default using port 80 if you don’t
assign other ports for the web application, so the port is changed to 80 in Central Administration.
To be able to access the web application, you need to add binging for the web application in IIS(please make sure that you have added the host name in DNS).
For example, SharePoint – 32298, you need to create the binding for the web application in IIS as the image below:
Best regards.

Good exception handling policy for Java web application

I'm looking for a good exception handling policy for Java web application. First I found this Java exception handling best practices - How To Do In Java which says that you should never catch the Trowable class nor use e.printStackTrace();
Then I found this Oracle page The Message-Driven Bean Class - The Java EE 6 Tutorial, which does just that. So now I'm confused. Is there a good page online for an exception handling policy for Java EE Web applications? I have a hard time finding one. I've read that you should not catch the Exception class. I've been catching it previously to make sure that some unknown exception doesn't slip through early in the loop and stops all other customers from executing later on in the loop. We have a loop which runs once a minute implemented using the Quartz framework. Is it OK if you just change the implementation to catch the RuntimeException class instead of the Exception class? We're using Java 7 and the Jetty Servlet Container.

I'm looking for a good exception handling policy for Java web application.
If you have not done so I suggest you start by reviewing the several trails in The Java Tutorials.
Those trails cover both HOW to use exceptions and WHEN to use them.
This trail discusses the 'controversy' you mention regarding 'Unchecked Exceptions'
http://docs.oracle.com/javase/tutorial/essential/exceptions/runtime.html
Unchecked Exceptions — The Controversy
Because the Java programming language does not require methods to catch or to specify unchecked exceptions (RuntimeException, Error, and their subclasses), programmers may be tempted to write code that throws only unchecked exceptions or to make all their exception subclasses inherit from RuntimeException. Both of these shortcuts allow programmers to write code without bothering with compiler errors and without bothering to specify or to catch any exceptions. Although this may seem convenient to the programmer, it sidesteps the intent of the catch or specify requirement and can cause problems for others using your classes.
Why did the designers decide to force a method to specify all uncaught checked exceptions that can be thrown within its scope? Any Exception that can be thrown by a method is part of the method's public programming interface. Those who call a method must know about the exceptions that a method can throw so that they can decide what to do about them. These exceptions are as much a part of that method's programming interface as its parameters and return value.
The next question might be: "If it's so good to document a method's API, including the exceptions it can throw, why not specify runtime exceptions too?" Runtime exceptions represent problems that are the result of a programming problem, and as such, the API client code cannot reasonably be expected to recover from them or to handle them in any way. Such problems include arithmetic exceptions, such as dividing by zero; pointer exceptions, such as trying to access an object through a null reference; and indexing exceptions, such as attempting to access an array element through an index that is too large or too small.
Generally don't catch an exception unless you plan to HANDLE the exception. Logging, by itself is NOT handliing.
First I found this Java exception handling best practices - How To Do In Java which says that you should never catch the Trowable class nor use e.printStackTrace();
That article, like many, has some good advice and some poor or even bad advice. You get what you pay for!
I've read that you should not catch the Exception class.
Ok - but all that does is indicate that a problem of some sort happened somewhere. Not very useful info. Java goes to a lot of trouble to provide specific exceptions for specific problems.
I've been catching it previously to make sure that some unknown exception doesn't slip through early in the loop and stops all other customers from executing later on in the loop.
If the exception is 'unknown' then maybe it NEEDS to 'stop all other customers from executing later on in the loop'.
That is EXACTLY why you don't want to do that. You need to identify which exceptions should NOT stop processing and which ones should.
Some 'unknown' exceptions can NOT be recovered and indicate a serious problem, perhaps with the JVM itself. You can NOT just blindly keep executing and ignore them without risking data corruption and/or the integrity of the entire system Java is running on.
Is it OK if you just change the implementation to catch the RuntimeException class instead of the Exception class? We're using Java 7 and the Jetty Servlet Container.
No - not if you want a well-behaved system.
Don't catch exceptions unless you HANDLE/resolve them. There are times when it makes sense to log the exception (which does NOT handle it) and then raise it again so that it gets handled properly later. Yes - I know that is contrary to the advice given in that article but, IMHO, that article is wrong about that point.
If you have ever had to maintain/fix/support someone else's Java code you should already understand how difficult it can be to find WHERE a problem occurs and WHAT the exact problem is when exceptions are not handled properly.

One Search service application for multiple web applications in a single server

We are planning to host 17 Web applications in a single Server. Do I need to create search service application for each web application or I need to create one Search service application , create a Content source for each web
application and create a Result source for filtering. Which is the best approach. And which approach takes more RAM memory.
In my application I am using Search web part, "Recently Changed Items", "Popular Items" web parts. when I created only one one Search Service application for all web applications and using Result sources ,
I am not getting the results. What could be the problem.

Hi,
One SSA is ok, but you should think about access rights. If the access is clear cut between all the web apps you should be ok with one SSA. Multiple result sources limiting on content source also works, but could easily be bypassed.
Multiple SSA's will eat up RAM/CPU like a mother :)
As for popular etc.. it could be due to how those sources are set up, but haven't investigated or tested this much.

Office Web Apps - how to disable office web apps features for one web application

ENV: Sharepoint 2010 farm with office web apps + fast search
I have the requirement for one web application to open all its documents in client applications - I can enable feature "OpenInClient". This web application uses team site template and other web application also uses team site template. ( feature
stapling ruled out) Now I can run powershell cmdlet to enable this feature on all the currently existing site collections. But the requirement is to enable this feature for all the future site collections. This web applications has 60 k site collections
and atleast more than 10 site collections get created each day and they dont like the option to run a powershell script each day to activate this solution.
Is there any other way to by default activate new site collections on this WA to open in client applications by default (can we disable this office webapps features only on one web app)?
VM

I have learnt from this forum that it is not possible to turn off Office web apps on single web application. The line of control lies at farm level and then at site collection.
