Servlets Vs Standalone Application?

Servlets Vs Standalone Application?
I know this is an extremely broad subject, but put very simply can anyone give me a basic list of pros & cons in writing an application on a network with either of the two mentioned technologies?!?
We will need security, efficiency, speed etc as well as an intuitive interface!!
Not much to ask i know!
cheers now!

Servlets:
+Easier to deploy
+Upgrading easier (Just upgrade one instance)
-Interface somewhat limited
+Security is centralized
Standalone
-You have to deploy to every client
-Upgrading is cumbersome, especially when the new version is not backwards compatible, and you need a big bang upgrade.
+Highly interactive interfaces (Swing)
-Security can be a problem (e.g. clients can be forged), when it is not centralized.
The speed of the application is dependent on the kind of application. It depends on the complexity of the UI, whether data is on a central server or local, etc.

How to use JDBC Connection Pools in a standalone application?

Hi, there,
I have a question about how to use JDBC Connection Pools in an application. I know well about connection pool itself, but I am not quite sure how to keep the pool management object alive all the time to avoid being destroyed by garbage collection.
for example, at the website: http://www.developer.com/java/other/article.php/626291, there is a simple connection pool implementation. there are three classes:JDBCConnection, the application's gateway to the database; JDBCConnectionImpl, the real class/object to provide connection; and JDBCPool, the management class to manage connection pool composed by JDBCConnectionImpl. JDBCPool is designed by Singleton pattern to make sure only one instance. supposing there is only one client to use connection for many times, I guess it's ok because this client first needs instantiate JDBCPool and JDBCConnectionImpl and then will hold the reference to JDBCPool all the time. but how about many clients want to use this JDBCPool? supposing client1 finishes using JDBCPool and quits, then JDBCPool will be destroyed by garbage collection since there is no reference to it, also all the connections of JDBCConnectionImpl in this pool will be destroyed too. that means the next client needs recreate pool and connections! so my question is that if there is a way to keep pool management instance alive all the time to provide connection to any client at any time. I guess maybe I can set the pool management class as daemon thread to solve this problem, but I am not quite sure. besides, there is some other problems about daemon thread, for example, how to make sure there is only one daemon instance? how to quit it gracefully? because once the whole application quits, the daemon thread also quits by force. in that case, all the connections in the pool won't get chance to close.
I know there is another solution by JNDI if we develop servlet application. Tomcat provides an easy way to setup JNDI database pooling source that is available to JSP and Servlet. but how about a standalone application? I mean there is no JNDI service provider. it seems a good solution to combine Commons DBCP with JNID or Apache's Naming (http://jakarta.apache.org/commons/dbcp/index.html). but still, I don't know how to keep pool management instance alive all the time. once we create a JNDI enviroment or naming, if it will save in the memory automatically all the time? or we must implement it as a daemon thread?
any hint will be great apprieciated!
Sam

To my knoledge the pool management instance stays alive as long as the pool is alive. What you have to figure out is how to keep a reference to it if you need to later access it.

Standalone application through BOE SDK

Hi,
I am new to SDK development so trying out different things with the SDK. The first experiement that I did was trying to build a standlone application through BOE SDK. The main purpsoe of this application is to connect the enterprise and get some details about an info object. But while building out this application I have noticed few issues:
   1. The getInstalledAuthIDs method of the ISessionMgr class is not returing any available authentication types.
   2. While trying to login using the logon method of the ISessionMgr using the secEnterprise as Enterprise, it's throwing the following exception:
    com.crystaldecisions.sdk.exception.SDKException$PluginNotFound: The plugin secEnterprise does not exist
     at com.crystaldecisions.sdk.occa.pluginmgr.internal.PluginMgr.getPluginInterface(Unknown Source)
     at com.crystaldecisions.sdk.occa.security.internal.o.a(Unknown Source)

     at com.bo.boesdk.tutorials.Login.createEnterpriseSession(Login.java:41)
     at com.bo.boesdk.tutorials.Login.main(Login.java:55)
I have noticed that all tutorials associated with SDK are all using eithe JSP/ASP to demonstrate features of SDK. There is none exists on using the standalone application. Is it we can't build any standalone application using the BOE SDK?

The BusinessObjects Enterprise SDK is only tested and fully supported in web applications - that's the reason why the documentation only describes its use in JSP/Servlet code.
As for the specific exception you're getting - it may be caused since you're missing jar files.
If using XI Release 2, then I'd reference the jars found by default in <install>\common\3.5\java\lib and <install>\common\3.5\java\lib\external.
If using XI 3.0, then I'd use the documentation found [here|https://boc.sdn.sap.com/node/7298].

How to use quartz to integrate a standalone application in a webserver

Can anyone help me in using quartz where i need to integrate a java standalone application into the webserver..I am developing an application using jsp and as part of a task i had created a standalone application in java and now i need to integrate this standalone application into the webserver because it needs to run as a webapplication.

Hai sam,You gave us many valuable suggestions in the past.We tried all of those methods to make our application run as per scheduled but we failed.We have not yet tried the servlet method,which you suggested in your last reply. Actually we tried to use the os scheduler for this purpose and couldn't do it at the end.So can you suggest the way in which we have to write the servlet and invoke it. We dont need all the details.Just give us the idea of what this servet contains actually and how it works.We will try to do it.Thank you,

Looking for a standalone application/system menu

Most (all?) desktop environments features some kind of application menu in the panel. But for the people running more lightweight environments (like just a tiled wm) have no reason to have an extra panel around just for the menu.
I know about application launchers, such as launchy and gmrun, but the thing I'm looking for is something that could give me a list of all "bigger" programs installed, grouped by category. Because, simply, I can never remember all stuff I've installed over the years.
So I'm thinking: there must be someone out there that has developed a standalone application menu?
Either the program could just scan the "/usr/share/applications" direcotry, or one could try to extract the menu part from a panel program, such as lxpanel?

Hey, adeskmenu seem to be exactly what I'm looking for! Thanks a lot! :-)
(now just need to find out why the aur version crashes... no problem, though. seems to be other versions around that works)

Standalone application can't get JDBC data source from Weblogic 10.3

We have the following configuration :
A Weblogic server 10.3 (default installation).
The server contains a JMS queue (jndi name: "DMQ") and JDBC data sources (jndi names: Oracle thin XA - "dataSource", MS SQL - "dataSource1")
We have built wlfullclient5.jar for Java 1.5 ([http://edocs.bea.com/wls/docs103/client/jarbuilder.html#wp1078122]) (according to the docs)
And now we use a test standalone application with the wlfullclient5.jar :
public static void main (String[] args) throws NamingException {
bq. Hashtable<String, String> env = new Hashtable<String, String>(); \\ env.put(Context.+INITIAL_CONTEXT_FACTORY+, "weblogic.jndi.WLInitialContextFactory"); \\ env.put(Context.+PROVIDER_URL+, "http://serv1:7001"); \\ env.put(Context.+SECURITY_CREDENTIALS+, "weblogic"); \\ env.put(Context.+SECURITY_PRINCIPAL+, "weblogic"); \\ InitialContext ic = new InitialContext(env); \\ \\ System.+out+.println("Get DMQ"); \\ ic.lookup("DMQ"); \\ System.+out+.println("Get dataSource"); \\ ic.lookup("dataSource");
bq. System.+out+.println("Get dataSource1"); \\ ic.lookup("dataSource1"); \\ System.+out+.println("Done"); \\
Here is the output when connected to WLS 10.3:

But at the same time the output when connected to WLS 10.0 is :
Get DMQ \\Get dataSource \\Get dataSource1 \\Done
(so that the test passed)
Could you give me a piece of advice ?
Thanks,
Sergey

I hit the same problem as yours. This issue is caused by JDK version. The JDK used by Weblogic 10.3 is java 6, while your client program's jdk version is java5. So change the both of them to java 6. This issue will be fixed.
Don't forget to rebuild the wlfullclient.jar which also should be java 6.
Good luck!

Run standalone applications on E-Business Suite Application Server

Hi,
Environment Details:
Database - 10.2.0.3
Apps. - 12.0.3
We have a 6i client-server Forms & Reports application that we want to web-enable. This is a standalone application that has no integration with the E-Business Suite. We would like to use the E-Business Suite application server forms and reports servers to run this application too.
I had two questions:
1. Are there any documents available that would document best practices for such a scenario?
2. Is it possible to create a standalone report server on the E-Business Suite reports server or is there a way to integrate the standalone application reports with the EBS report server?
Thanks,

How to create a servlet in PAR Application

Hi Experts,
I want to create a servlet in PAR application. This servlet should be capable of accessing the functions of other java files included in PAR Application. Servlet should be capable of accessing the functions say doContent(req, resp) of any class of PAR application.
Is it possible to create Servlet in PAR application?
I created one servlet but unable to declare its information in Deployment Descriptor.
Because the deployment which is provide ie portalapp.xml doesnt allow us to write tags like <servlet-name>, <servlet-mapping>, <url-pattern> etc. These are necessary for declaration of servlet.
So how can i write a complete working Servlet under PAR application?
Please help and replies will be appreciated.

uacc.setPasswordChangeRequired(false);
uacc.save();
uacc.commit();

Db with a standalone application

hi all.
i'm sorry if this is not the right forum for this question but it's the best place i could think of...
up untill now when i needed to save data i would usually use databases (mysql in most cases) or xml.
this worked fine because i mostly work on web-based application so there's a db server installed on the server.
what if i want to use a database on a standalone application? it's not a good solution to tell everyone which will use the application to download a db server and install it, right?
so what do i do? thanks!

One possibility is to use a Java-based embeddable database, such as hsql db (there's a t least another good choice, which escapes me this morning).

DAQmx drivers needed to calculate statistics in a standalone application ?

Hi!
My standalone application analyzes measured data and saves statistics into Access database. It uses Statistics express VI, among the others. It does not use any data acquisition library. I've made an installer to install it on my customer's computer. After installation I tried to run the application but an error occured (see below).
Well, it works now (after few hours). But my opinion is that my solution is a little bit strange: I simply installed DAQmx drivers.
1. Is this a bug ?
2. How to explain my customer why does he need 1GB of hardware drivers ?
Fortunately, It was not necessary to use any special procedure tu run Database Connectivity Toolset: see this link, for example
Best regards ,
Ljubo.
P.S.: Developer Suite 8.6, Win XP Pro, DAQmx 8.8, MS Office 2003.

Hi Dennis,
let me repeat the whole story once again:
About
two years ago the same problem occured (with LabView 7.0 or 8.0, I
don't know exactly). Our local NI representative happened to be present
and we discussed the problem but we didn't find the solution. Instead
of using Statistics Express VI I made my own subVIs and the problem was
solved (and forgotten).
I've already checked my
customer's computer this morning and everything seems to be OK. DLL
library lvanlys.dll is installed in "data" folder.
To eliminate unnecessary details I've created a new project (see the attachment, please).
I
installed the program on my colleague's PC (my colleague never used
LabView in his life). The result is the same. You can see the error
report in the second attachement.
Then I've copied lvanlys.dll
file to all folders where programs usually search libraries: Windows,
Windows\system, Windows\system32 and Program Files\Mean4V. But program
can't find the library NI_AALBase.lvlib.
Obviously,
installation of DAQmx drivers adds something which is missing in my
build specification. I hope someone could explain what I'm doing wrong.
With best regards,
Ljubo.

MyRIO standalone application not working, but works well when connected to PC (NI vision + webcam)

Hi,
I have a program that can detect motion that occurs in my room using a webcam and will send a picture to my gmail account if motion detected. The program works fine when myRIO is connecting to PC (with the webcam connects to myRIO). However, after I created a standalone application, it's not working. Even the VIs within the first frame of the flat sequence (turn LED on) was not working. The standalone program will work if I disable all of the vision-related VIs. Any suggestions? Thanks!
I got the driver installed and the webcam connected, so that shouldn't be an issue.
Thanks in advance.
-Robin

I have a 30 GB version of the same. I also got some external speakers for it, UBL I think they are called. I find there is something very odd about whether you charge it up or not. It seems to over-charge sometimes, and then everything freezes. As for connecting to the PC, no chance. After an initial burst on another machine, and after installing itunes on this computer, there is no recognition of the one by the other at all. Plus freezing and locking up. Plus freezing the PC as well, it is very tedious. So no answers, only commiserations. I think Apple are doing a very poor job on this ! And their help facility seems quite hopeless !

Publishing message to Topic from a standalone application.

I have a standalone Java program which will publish a message to the TOPIC. I have found the code to publish to the topic. Please anyone of you can tell me, if I can do it from the standalone application and if yes then how, please provide a code example if possible. We need to specify JNDI's, so tell me where we configure these JNDIs and how would my standalone program would connect to it.
