  • How to make a Struts message null after used in JSP?

    Hi,
    In the context of Struts/JSP,
    An action class might write error messages by
    ActionError msg = new ActionError("msg.request.something");
    ActionErrors msgs = new ActionErrors();
    msgs.add(ActionErrors.GLOBAL_ERROR,msg);
    saveErrors(request,msgs);
    This message will produce a popup modal window by the following JSP code:
    <logic:messagesPresent>
    <html:messages id="error">
    <!--<li class="infomsg"><bean:write name="error"/></li> -->
    <script>javascript:alert('<%=error%>')</script>
    </html:messages>
    </logic:messagesPresent>
    The problem is that this JSP page is shared by serveral actions: when another action invoke this page again, the previous error message will take effect again.
    So my question is how to make message null after used once by its author.
    Thx.
    PY

    msgs = null;

  • How to make an standalone java application that uses mysql driver

    Hi,
    I have an application that makes connection to a mysql database, on my computer, I set on classpath the driver address, so everithing works fine.
    The problem is that I want to execute my application from other computers, where the classpath does not have the drivers.
    So my question is how can I package the driver? so, everybody can run my application from a Jar, for example.
    thanks in advance,
    - Susana

    Nobody answered me, but I post the solution I found, that maybe can help somebody else with this problem:
    I packed all my application sources (.class) and the drivers sources (.jar) with the tool: FAT JAR. It is an Eclipse plug-in. And now I can run mi application from the resulting Jar in other machines without installing the conector.
    Bye,

    Hello everybody,
    I'd like to know if someone managed to use the Simple Java Bean Generator, useful tool for web dynpro application in order to import complete database model.
    I read the doc, and I think it's usable for SQLServer database. My command is as follows :
    java -D com.sap.test.DBTest com.microsoft.jdbc.sqlserver.SQLServerDriver sa 123erty TSP c:\GenerateDB CONFIG
    where CONFIG is my database name, sa/123erty the couple login/pwd, and TSP the pattern (what does it mean pattern in this case ?).
    When executing this command, the response is : datasouce not found and driver not specified...
    I don't understand, can someone help me please ??
    Thanx.

  • How to pass a populated Java bean to a jsp

    Hi,
    I'm new to J2EE world. I want to know how should I pass a populated Java Bean (not EJB) to a JSP without displaying that JSP in the next step. I would be much grateful to anyone who gives a solution to my problem.
    Thanks in advance
    With best regards

    Urk?
    A JSP is meant to be displayed. If there's business logic in that JSP, get it out of there. Process the bean as needed on the server side and send the flow on to some view that actually should be displayed.

  • How to include PJC and Java Beans in forms

    I have tried a lot to include java codes in my forms ..So I decide to start with ProgressBarPJC(cause it is tested and provided with demo) but I could not set implementation class of java bean object to
    oracle.forms.demos.ProgressBarPJC it does not accept it but it accept ProgressBar instead of ProgressBarPJC. I don't know why? I have made changes in Forms90_builder_classpath to access f90all.jar and progressbar.jar. I have Progressbar.class and progressbarpjc.classs both but i don't know how to set implementation class to ProgressBarPJC.
    don't you think there is lots of configuration and path setting to use any JPC or Jar in forms? I am totally confused with this integration.
    Please solve this matter
    Thanking you,
    Neeraj

    and even more information samples and step by step instructions are on the Java spotligh on the Forms Upgrade Center : http://otn.oracle.com/formsupgrade

  • How to deploy the wrapped Java Bean on PowerBuilder

    Using the JavaBeans Bridge for ActiveX Packager, I could generate the .tbl and .reg files for my Java Bean. Since I am a 100% Java guy and don't have much knowledge of PowerBuilder, I don't know how to deploy this on PB. When I try to register an OLE, PB looks for the files with an extension .ocx but not .tbl. Please let me know how I can see my wrapped up Java Bean on PowerBuilder or on VB.
    Thanks a lot in advance.

    I found it, I have to update the system registry with the .reg file and then the java bean automatically gets listed in the controls list in PB.

  • Challenge: How to create an BMP Java Bean from a DBF Database??

    Hello guys....
    This is my challenge and looking for some aim:
    I was asked to create an application that must read from an existing DBF Database of products (That is already used by an administrative system) an build a Price List in Real Time. The program must be accesible through Intranet using a web browser.
    The Appplication Client must be a faster GUI (Applet or App) that do not cause interference in the normal functions of the Administrative System that owns the DBF Database, but must propagate any change maded to the database in real time.
    I was thinking to use BMP Entity Beans for manage the DBF Tables and Utility Beans to avoid constan access to the tables (As in Duke�s Bank Tutorial) but i do not know how to create a BMP Entity Bean without a Database that do not have an JDBC Driver ?????????
    i was able to gain access to DBF TAbles using an small library called TinySQl but i get lost in this point....
    any suggestions/comments about following matters will be apreciate:
    1.- Application Performance Tips
    2.- A better JDBC Driver for DBF Databases
    3.- Application�s Security
    4.- User Management
    5.- Any comments in general !!!!!!!!!!
