Can I use PropertyResourceBundle in my Servlet?

hello ,
my servlet ,using PropertyResourceBundle,throws FileNotFoundException .
from error log.
java.io.FileNotFoundException:res_ja_JP.class
java.io.FileNotFoundException:res_ja.class
java.io.FileNotFoundException:res_ja_JP.class
java.io.FileNotFoundException:res_ja.class
resource file is 'res.properties' !!!.
why servlet runnner will not use it?
on JDeveloper debugging enviroment my servlet works well, and also Tomcat Servlet Engine too.
please tell me how to use property resource.
thanks advance.

Thanks gimbal2.
What I'm aiming to do it a bit too complex for JavaScript. I'm hoping to be able to process some (quite large) images server-side, which may be in a queue, and will be saved in an images folder. I'd like user's to be able to submit requests for an image to be created without having a Java front end, then returning and checking whether the image has been processed.
The images are created by merging different sub-images together in different patterns, transforms, rotations which are defined by the user on the JSP page.
If the "invisible" server-side nature of the image processing I suggest is definitely not possible using a Servlet, would it be a better idea to use a hidden Applet and LiveConnect?

Hi,
You can try a package named: JTwain, which is available at http://asprise.com/product/jtwain.
JTwain supports all kinds of digital cameras and scanners. You can use Java to access, contorl digital cameras and scanners, and of course, to acquire images with flexible settings.
The developers' guide is available @ http://asprise.com/product/jtwain/devGuide.php
In the simplest case, one line of Java code can solve your problem.
Good luck!

Can we create a object for servlet

and can we use constructor inside a servlet .If yes at what situations we can use

Servlet is an object. Not sure what you need. You can create objects inside a Servlet, or any Java class...
and can we use constructor inside a servlet.Sure, but most people don't because Servlets are container managed (i.e. you don't instantiate it)
If yes
at what situations we can useNot sure what you are asking here, but you can instantiate the servlet anywhere.

Can I use data from Servlet in my static html page?

First of all, I can NOT use jsp because of web server's restriction.
I have a servlet which will give me some image links in html file via doGET and doPOST method. I also need the sizes of the images and compress the images if too large.
My question is how I can pass the image sizes to the html page and how I can use them in html files.
Please advise me some solutions to this problem.

Yeah, you have 2 choices:
1) Change your web server to one that allows JSP.
2) Re-build the JSP system from scratch so that the one you make will work in your server. This would involve changing your so called static HTML to have markings (like <% %> tags) where you should insert the values you need to insert. You would then have a servlet that reads the 'static' HTML, parses our the insertion tags, and inserts the values. It would then stream the results back to the user.
Of course, your HTML is not really static, it is dynamic because the values you are inserting are capable of changing.
If you don't want to upgrade the server to one that supports JSPs (if yours really doesn't), the have fun making your own system.

How can i Use SERVLET with RMI to avoid trust certificate

I know that for begining RMI, you must launch the server and the client.
for the server i use :
java -Djavax.net.ssl.trustStore=server.keystore -Djavax.net.ssl.keyStore=server.keystore -Djavax.net.ssl.keyStorePassword=server TestServer
for the client I use :
java -Djavax.net.ssl.trustStore=client.keystore -Djavax.net.ssl.keyStore=client.keystore -Djavax.net.ssl.keyStorePassword=client TestClient
and all work fine.
but i want to use a servlet for rmi client and i wrote this:
public class AppelServlet extends HttpServlet
     public void doPost(HttpServletRequest request, HttpServletResponse response)
     throws ServletException, IOException
          try
               System.out.println("Registering secure RMI socket factory ...");
               java.rmi.server.RMISocketFactory.setSocketFactory(new SecureRMISocketFactory());
          TestRemote test = (TestRemote) Naming.lookup("rmi://127.0.0.1:7123/TestClient");
String reponse=test.toLowerCase("HELLO WORLD");
               System.out.println("la reponse est : "+reponse);
     catch (Exception e)
          System.out.println("test client exception: " +e);
PrintWriter out = response.getWriter();
          response.setContentType("text/html");
and i have the following error on tomcat:
Registering secure RMI socket factory ...
test client exception: java.rmi.ConnectIOException: error during JRMP connection
establishment; nested exception is:
javax.net.ssl.SSLHandshakeException: Couldn't find trusted certificate
i think i must precise how to indicate the truststore like in the first case.
help me please.
hamdi

Hi,
Try doing the following steps.
Assuming you have a certificate obtained
Export the certificate into a .cer file.
On IE, goto tools->internet options->content->certificates, and export to a .cer file.
Using keytool of java import the certificate to the store that can be used doing the following command.
keytool -import -alias <ailas> -file < .cer filename> -keystore <storename here>
set the javax.net.ssl.trustStore and javax.net.ssl.trustStorePassword properties at the command prompt using the command below.
java -Djavax.net.ssl.trustStore=<storename> -Djavax.net.ssl.trustStorePassword=<password> <classname>
Let me know if this helped.
Also take a look at this link for using RMI with SSL

Can you help me to find where is wrong?Very thank!

You are trying to pass the current URL to the servlet
from the applet, right?
Well, what I put was correct. Your servlet code is
trying to read some information from session data.
request.getInputStream() is not the IP address of
anything...see

Can I use servlet as my welcome file

How can I use servlet as my welcome file? I know how to use jsp or html pages as my welcome file but that doesn't work for servlets. I modified my web.xml for making jsps and html as my welcome pages but that <welcome-file-list> tag is not working for servlets.

This was a bug that occured in older Tomcat programs, not sure if it still occurs or not.
Basically, when this happens, you have to have a physical file with the welcome file name. So you would have to create a file named index.do in each of your directories you wanted the welcome to work for. The index.do wouldn't have to actually do anything. It just had to exist. Then when the URL was used to create content, the servlet would be called to create that content.

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

Using a class or servlet that implements Serializable

Hello everyone,
Can someone please help me. I need to make a program that uses a class or servlet that implements Serializable and then use the values of the variables in servlets.
The first is using it to validate login. then changing the color of the background, header and footer of each servlet.
the variables in the Serialized file are all Strings for color, username, password, header text and footer text.
I tried using the applet tag to run the class in the servlet but it is not working.

It's not working because you seem to be making random guesses what servlets, serialization and files are

How can I send XML to a servlet without a WebService?

I have created some XML on my Flex app now I want to send it
back to the Servlet, any suggestions on how to do this?
I don't have a web service setup, so I just need to do this
without a webservice.
I appreciate an help!!!!

Hi,
You can use HTTPService or RemoteObject.
If you are using HTTPService, then it is very similar to Form
post from a HTML page. HTTPService will allow you to select the
method (POST/GET) in which you want to send the data to the server.
You can add parameters with the data and the send the request to
the server. On the server side, you can either use JSP/Servlet/ASP
or any other server side scripting technology and access the
parameters using request.getParameter("<parameter name>").
Please find more details on how to pass parameters at the URL
below.
http://livedocs.adobe.com/flex/3/html/data_access_5.html#200238
If you are using RemoteObject, then you need to have
BlazeDS/LCDS on the server which will allow you to invoke methods
in any Java class. When invoking any method you can pass arguments
as you were invoking that method from another Java class. Please
find more details on how to use RemoteObject at the URL below.

Hope this helps.

How can i use tag library in the mvc?

hello
in some tag libraris such as jakarta tag library and jrun tag library,there is database
access tag, it provide convenient function to access database from jsp page,but i wonder how can i use such a tag within MVC architecture.
as we know,in MVC architecture,all requests from the jsp pages are submit to the controller servlet,then the controller manipulate ejb to access database,it don't allow the database access from the jsp page.
who can tell me how can i combine the tag library with mvc architecture appropriately?
thank you!

You can't! If you decide to limit the JSP to be part of the View component, obviously you should not include tags that directly access the database. If the strict MVC architecture is less important to you, then the tags can save coding time. It's your choice.

I have done an application to get the screen image and do upload file to server in a servlet with the http protocal.

Since the desktop image is on the client's local hard drive, you'll need to look at trusted applets first.
