Programmatically Registering a JSP/Servlet Portlet

???Programmatically Registering a JSP/Servlet Portlet???
OK, I have read all the literature on how to register a JSP/Servlet Portlet and have not seen any info on how to register a JSP/Servlet Portlet programmatically.
I know for sure that you can register a PL/SQL Portlet programmatically via a couple of SQL and PL/SQL scripts that were given in the PL/SQL PDK examples.
Bottom line, I want a way to register a new JSP/Servlet Portlet with ZERO GUI/User interface.
My questions are:
Is it possible to register a JSP/Servlet Portlet programmatically?????
If it is possible to register a JSP/Servlet Portlet programmatically, were is the info on it or can you give me some examples of it????
THANKS MUCH!!!

For a faster response, you may want to ask this question on the Portal Developer's Kit (PDK) Forum.

Do I have to register all *.jsp servlets in web.xml?

All,
I'm hoping someone in this forum can help me. I'm working on a report generator that uses JSP to generate a template which is fed to a formatter. What I want is to programatically call the JSP without having to add an entry for every single report to my web.xml. As you can imagine this doesn't scale well since every time a new type of report is added, someone has to go edit the web.xml.
The options I can think of:
1) Pre-compile the JSP's
2) Have a servlet mapping where *.jsp "does the right thing" for me
3) ?
Any suggestions? I'm not sure which is the best/practical approach. I really want to get away from having to modify the web.xml for every single type of report that I can generate.
Thanks!!

Our web app is a web service where all requests get processed by an XFire servlet. So just adding the jsp on the disk somewhere won't do the trick. I have to register the jsp's.
Is there a better way to do this?

Metadata problem with JSP/servlet application

Hi,
I developed a JSP/servlet test application that makes
use of kodo 2.2.3 STANDARD EDITION for its persitence.
I successfully compile and annotate the application.
I am also able to successfully generate the db
schema with schematool.
Unfortunately, when I run the application using
Resin 2.0.2, Kodo is unable to initialize properly.
Initially it was not able to find "system.prefs" file.
I fixed that by putting "system.prefs" in WEB-INF\classes.
Unfortunately, Kodo is still unable to initialize and
gives the following message:
The system could not initialize; the following registered
persistent types are missing metadata
or have not been enhanced:
[class com.dpov.purchaseorder.PurchaseOrder,
class com.dpov.catalog.Product,
class com.dpov.uidgen.counter.Counter,
class com.dpov.catalog.dao.jdo.CategoryHierarchyEntry,
class com.dpov.catalog.dao.jdo.CategoryHierarchyDAO,
class com.dpov.pricelist.PriceInfo,
class com.dpov.pricelist.PriceList,
class com.dpov.catalog.Category,
class com.dpov.lineitem.LineItem,
class com.dpov.dealer.Dealer,
class com.dpov.user.User,
class com.dpov.customer.Customer].
I use "system.jdo" to describe metadata for the enhancer.
I tried to put it both in WEB-INF\lib and WEB-INF\classes but
it still fails.
Please note that:
1) my classpath variable is not set
2) my application's class file are in WEB-INF\classes
3) kodo jars are in WEB-INF\lib
4) mysql jdbc driver is in WEB-INF\lib

Overriding default jsp servlet mapping

I want to override the default jsp servlet mapping under a specific directory. I have the following entries in my application's web.xml file:
<servlet>
<servlet-name>CMS</servlet-name>
<jsp-file>/template/main.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>CMS</servlet-name>
<url-pattern>/raw/*.html</url-pattern>
</servlet-mapping>
<servlet-mapping>
<servlet-name>CMS</servlet-name>
<url-pattern>/raw/*.jsp</url-pattern>
</servlet-mapping>
When I call up the page /raw/test.jsp, it is processed as a normal jsp page instead of by the custom mapping. Calling up the page /raw/test.html works as expected.
I am using the embedded server under JDeveloper 10.1.2.1.0.
Isn't an entry in the application's web.xml file meant to override system wide mappings?
Thanks for any help.

I'm no expert on this but I have a hunch. 1st of all, your using a servlet mapping for a JSP. That's good and well but it seems that the container is complaining that there is no servlet named org.apache.jsp.jsp.info.ContactUs_jsp. In other words it looks like the JSP has not been compiled. At least not yet. Maybe try two things. Visit the JSP once with a browser at it's actual path "http://localhost:8080/<webapp>/jsp/info/ContactUs.jsp" the coerce a page compile. Then try it with your new mapped path. You see, just telling the container that there is a servlet mapped to the new URL doesn't force the container to generate the class. Something or someone must generate the servlet class file.
Honestly, I'm not sure of what your end goal is but maybe you might consider using a JSP pre-compiler? Or even better, register a servlet at the mapped path that fowards all requests into the desired folder.

Different Classloader for JSP, Servlets?

Hi!
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??
          I've previous posted an article with the subject "JSP - Servlet - Static
          Code in Classes".
          I will try to describe my problem better:
          At server startup I pass information to my startup servlet, for example
          the user and pw for our connection pool. The startup servlet instanciates
          the class Global which creates a db-pool with the user and pw getting
          from
          the startup-servlet.
          startup-servlet {
          public void init(ServletConfig config)
          Global.init("user","pw");
          The class Global looks like this:
          class Global {
          static {
          // register jdbc driver
          // store file informations
          static public init(string, string) {
          // init the connection pool with user and pw
          static public getConnection() {
          // returns connection from pool
          All our other servlets then just use the methode Global.getConnection()
          and other methods from the class Global.
          All servlets works perfect and can access the db-pool.
          When a jsp-file is called which also uses the methode
          Global.getConnection(), a new Instance of the class Global will be made.
          In order to init all values again, I would have to call the
          Global.init(user, pw) methode again.
          So my question is: Why does the jsp file causes a new instance of the
          class Global?
          Does the WL5-JSP-servlet use an other classloader then the other
          servlets??


I am seeing the problem is sp3. I can't use sp4 becuase form based

JSPs&Servlet

Hi All
i am new to portal, and i have a question, i have a jsp page(portlet) , this jsp submit to a servlet that retrieves data from a database table, and this servlet is expected to go to the same jsp page and display the results,
i tried to use : Forward i the servlet but it failed,
then i used response.sendRedirect and kept my Vector (results) in the session object in the servlet
but i couldn't retrieve it in the JSP
How can i solve this, or what is the most suitable solution for what i need t do??
please reply

getTenders is a method that connects to my table and retrieve my data

How can i display data on tha same page in jsp/servlet

Hello friend,
I am storing 50 items in a dataBase. i ve two buttons/links name previous and next. i ve to display 10 items each time in the same page when i click next button and the revrese for previous. through JSP/Servlet.
Any suggestions will be appreciated.
chintan anand

I'm not sure this is the best practice... try to add the item in the arraylist, then when u click next button, add 10 to the counter. subtract if it is a previous button. thats it!
ex..
for(int x=counter;x<=arraylist.lenght();x++)
....print item here......

hello,
there are multiple documents out there, describing the oracle reports server setup. try doc.oracle.com for documentation.
also it is part of the online-documentation.
you need to install 9iAS enterprise edition. the server is pre-configured and will listen to the url http://yourserver/dev60cgi/rwcgi60.exe
passing only this url you will get a help-screen, describing the syntax.
regards,
the oracle reports team

How can I call EJB from JSP/Servlets in iWS?

Hi!!
My JSP/Servlets are on iWS, and I deploy EJB on iAS.
In this case, I don't know how JSP/Servlet call EJb on iAS.
I'd like to know how I can set JNDI name in JSP/Servlet on iWS.
I will thank you if you give me a simple example source using JSP/Servlet
and EJB.
Thanks in advance!!!

Park,
Why Are you running your JSP/Servlets in iWS instead of iAS? For whatever
reason,
look at the Converter sample from iAS. You will be doing RMI/IIOP in this
case and the sample explains in detail what to do.

How to use connection pool in jsp/servlet ?

I found I can "lookup" it in either java beans/servlets/JSP using JNDI. why?
what is the best practice to use it in a jsp/servlet web app considering JNDI lookuping expensive?
Thanks!
Bo

Huh?
You can lookup a JNDI resource from anywhere in java code you want to. As long as you have a repository set up to search on :-)
Of course whether that resource is available or not is a different matter. If you let the server set up the JNDI resource for you, then you can't run it standalone outside the server without something else setting the same thing up :-)
So its not so much a limitation of beans, but just the environment you run the code in.
Best practice? Don't write sql queries in JSP pages :-)
For the rest you might consider the DAO pattern. Or ignore SQL altogether and let hibernate do the work there for you.

How to implement this function in JSP/Servlet env?

Hi all,
I working on a project, it provides functionality to upload file using JSP/Servlet. In the first JSP page, there is file location and submit button. After user select a file to upload and click submit button, a message, like "sending file to XXXX", will be shown on the screen. Once uploading and validation are done on the server-side, a successful/error msg will be shown to user.
Here I have a question for the "sending..." msg and the successful/error msg. They should be put in one jsp page or in two separate page? how to implement them?
Thanks for any help!
Tranquil

For the sending message... Well, the thing is, when you click submit, it's sending the file to the server and the server is processing it, and this is all done before the "complete" page is sent to the server. So one would need to use some Javascript on the page before the actual submit happens to show some message. This is done on Ebay when you put something for sale, you can upload an image, and there is a little popup message telling you that it's uploading, and it is removed when the process is done. Now, I'm not sure the exact details of how this works, but my educated guess is this:
1) The onsubmit function of the form checks that the file upload fields have a value (no need to popup a message if no file upload, since that's what usually takes the time, although it could just be assumed there is a file). If a file is to be uploaded, or just want to show the message anyway, a new popup window is opened with the window.open method and the "sending" message is shown (either written via Javascript or just load a small web page to the window).
2) The popup window, since you can't transfer the window object from the form page to the next page, has to check window.opener for some value that the success/error page would have to set. The success/error page could use it's body onload function to set a variable in it's own window object to denote that the page is loaded. The popup window can use a looping check using setTimeout or setInterval in Javascript to check for window.opener.isLoadedVariable to be present, and if so, close itself.
I've never done that, but I see no reason why it wouldn't work.

Upload video by using jsp/servlet

I'm using jsp/servlet to upload video file but I have a problem.
This error occurs for preparing SQL statement when I cast OraclePreparedStatement.
It is " Error : weblogic.jdbc.rmi.SerialPreparedStatement

Please help me asap.

You need to use the Oracle jdbc driver. Apparently, the Weblogic JDBC driver is being selected:
weblogic.jdbc.rmi.SerialPreparedStatement
The Oracle JDBC classes can be found in <ORACLE_HOME>/jdbc/lib/See <ORACLE_HOME>/jdbc/readme.txt for how to specify the correct class path in the application.
I would have thought that the oracle JDBC driver would have been selected (if in the classpath) or an exception would be raised if the Oracle JDBC driver was not found.... because the code should include:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
This should load the Oracle jdbc driver and classes, not the weblogic ones. IF the Oracle JDBC drivers are not found, an exception should be raised...

File upload and download using jsp/servlets

How to upload any file to the server using jsp/servlets. . Help me out

You can also try the Jenkov HTTP Multipart File Upload. It's a servlet filter that is easy to add to your web-project. After adding it, you can access both request parameters and the uploaded files easily. It's more transparent than Apache Commons File Upload. There is sufficient documentation to get you started, and there is a forum if you have any questions.
Jenkov HTTP Multipart File Upload is available under the Apache license, meaning its free to use.
