    This may not solve your problem, but WL8.1 SP1 seems to have a problem with
              closing tags.
              Where you are using:
              <randME:number id="random1" range="10000000-99999999"/>
              ...try this instead:
              <randME:number id="random1" range="10000000-99999999"></randME:number>
              This problem is fixed in SP2.

  • 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.

  • How to process screen flow using PAPI and WAPI

    Dear all,
    I need to process the screen flow from PAPI or WAPI.
    I want to know which API(PAPI or WAPI) i should use and how to achieve that.
    as far as i know, there is two part in WAPI. (external to work portal, throungh the html process API, and internal to the work Portal, through the URLForAction java class).
    where can i get documentation for (internal to the work Portal, through the URLForAction java class)?
    With Regards,
    Wai Phyo

    Hi Bhaskar,
    If you zip probably the size would come less which may increase his performance a little. But I feel SAP also dont recommend this much load with PI.
    If I am in his shoes then I will do a simple FTP without using PI itself. Else will look into other options. Thats my two cents.
    Hope this alexs blog will give an idea to Sai:

  • Screen Saver using A3 Library

    Not major, but after upgrading to A3, I noticed that in SL System Preferences>Desktop & Screen Saver, it no longer recognizes my Aperture library. With A2, I was able to have the screen saver cycle through my Aperture library. Any ideas?

    Right, in Desktop there's an "Aperture" line item that doesn't do anything. In Screen Saver, there's no trace of Aperture.
    This is actually a problem for me as I tend to use the screen saver to let images "sink in" before I publish an album.
    I'm guessing this will get sorted in 10.6.3.

  • Using tag library to create a tree in jsp

    Hi,
    I want to create a tree in a JSP page whose node values are obtained from the database. The number of children of a particular node is known only during the construction of the tree.
    Root
    |---Node I
    |----Node I Level 1 Child 1
    |----Node I Level 1 Child 2
    |----Node I Level 1 Child 2 SubLevel Child 1
    |----Node I Level 1 Child 2 SubLevel Child 2
    |---Node I Level 1 Child 2 SubLevel Child 2 Subsub Level1
    |----Node I Level 1 Child 3
    |---Node I Level 1 Child 3 SubLevel Child 1
    |---Node II
    |---Node n
    These node values are obtained from the database. Any early help is appreciated. Helping in tree construction using JSP & Tag Libraries is requested (not swings). Also help me in deploying the same in Tomcat 4.0 server.
    Regards
    Vimal

    I am not very knowledgable in tag libraries. Bust using pure java, you can do something like this:
    Create Node and NodeRenderer java classes. These classes will have methods to access their siblings, parent and its properties and to render itself using HTML code. When you read the database to retreive the tree structure, you can build a hierarchy of nodes. Each Node can render itself and by doing an appropriate traversal, the tree can be rendered.

    Update: I just looked up the WL version and it's 8.1 sp3
              So, I guess, JSTL 1.1 (which includes jstl fn tags) is not supported by WL.... Someone correct me if I am wrong.

  • Purpose of TAG Library?

    What is the purpose of TAG library?
    I feel so hard while using Tag library in my JSP pages?

    Which taglibrary are you talking about? JSTL?
    If so, its purpose is just to control the flow of code logic and the data output in JSP. It is less or more a replacement of scriptlets, which are been discouraged since a decade. Scriptlets are considered a bad practice. Taglibs (and EL) forces you to write clean and well-MVC-formed JSP code. The JSTL core, format and functions taglibs are extremtly useful. The JSTL sql and xml taglibs are intented for quick prototyping only, in real you should be using Java classes for this to avoid tight coupling of database/business/model/view logic.

  • SQL in JSP - do I use JAVA code in % ... % or SQL Tag Library ??

    I have a small web app that makes needs to make about 12 SQL queries in a JSP and am trying to figure out what is the best way to do this
    I had initially coded this using plain JAVA code in the JSP as follows :-
    <%
    Connection conn = null;
    Statement st = null;
    ResultSet rs = null;
    try {
    st = conn.createStatement();
    rs = st.executeQuery("select .........");
    %>
    But then I came across the SQL Tag Library in an article and wonder if this is more efficient code?
    If so does anyone have a pointer to a good intro to these tags as they look complicated (I only am doing queries on the SQL database, no inserts or updates)

    Sometimes you've gotta do what you've gotta do.
    My rule is "no scriptlets".
    If you MUST access a database from a JSP, the only right way to do it is to use JSTL <sql> tags.

  • Is It legal to use Jakarta I18N Tag Library in my projects on work?

    I'm a JSP pages developer on my work and Jakarta I18N Tag Library is very usefull for me.
    But I'm not sure about licensing. Can I use this library in commercial projects?

    I am not a lawyer, but ys, the Apache Lisence allows you to use the library for such a purpose.
