Using a regular JAVA class (not java bean)

I have a regular class which I have created & I want to use in a JSP Page.
How can I import it?

Put a JSP import on the top of your page
<%@ page import="yourclassname" %>

Ok, this seems to be a long and convoluted path to do absolutely nothing.
You submit the form.
You run a servlet that gets the parameters correctly (good), creates a SimpleBean (good) and then sets this into request attribute space under the names "user" and "pass" - (why?)
You then forward to the jsp: submit.jsp.
Submit.jsp creates a new SimpleBean, and attempts to populate it with <jsp:setProperty>. You then call the issueData method on it.
Your complaint: Rows are being created in the database which have empty string values instead of the parameters you have passed.
So, why are the values blank? Where do you think these values should be coming from?
Looking at SimpleBean we find one mistake - you have mis-named your get/set methods.
To properly follow java beans standards, you should use camel-case for your methods.
Rather than getuserName() the method should be getUserName(). getpassword() should be getPassword() etc etc.
The method getUserName() defines a property "userName" for the bean.
Once that is fixed, lets go to submit.jsp. The <jsp:setProperty> statement will try and set all properties of the bean from the request parameters.
There are no request parameters "userName" or "password" so those values don't get set in the bean, therefore it uses their default value of empty string - "".
There ARE request parameters called "user" and "pass" but because they aren't properties of the bean, they get ignored.
As a result, the values are empty string, and that is exactly what gets inserted into the database.
Ways to fix this
1 - rename your parameters on your form to be "userName" and "password" to match the bean. That way the <jsp:setProperty> tag will populate them properly.
or
2 - Call issueData() method from your servlet after you have created the SimpleBean. Better in my opinion as you then don't have any scriptlet code on a JSP page.

Calling Portal Service using result as Java Bean Model impossible?

Hello folks,
we try to achieve to call a portal service (working) which gives as a result a list of object of type com.foo.Report. We want to make use of this class as a model class, so we have the class as a model node in the context. The class itself is part of the service DC.
Unfortunately at run time it gives us a NoClassDefFound Exception of com.foo.Report.
As the com.foo.Report is part of the same DC as the service, it is no option to add the PAR public part to the used DCs of the WD DC because then there is this type conflict when we call the service (service look up). Or am I wrong and this is the way to do it? I mean I struggled quite a while to get the service look up right and needed to remove all the PAR/lib used DCs from the used DCs of the WD Project, when I got it working this Model error came up. I also tried to put the Model class in a separate DC but that caused the same error.
how is it possible to call a Portal service from WD and using it's return vale as a Model class
our system iis 7.0.17

Using getRemoteAddr() in java bean

i am trying to get user ip
it is simple that we can get it in a jsp file with the following function
request.getRemoteAddr()
when i tried to put it into a java bean i will get an error message
cannot find symbol request.
any one ave any idea?

Hi,
You should never create threads on your own when using an application server.
These threads cannot be managed by the application server, this can result in large performance degradation and performance predictability.
If you continue t launch Threads form backing beans, Weblogic can no longer manage the machine, it thinks it knows all the threads created and manages those.
But your (rogue) thread interfere with the managed threads causing Weblogic itself to break in the end.
I think you can solve your issue by just using backing beans on the correct scope.

Using RAW in Jave Bean to store data in Oracle 8i database

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.
Jane

I have a question about using RAW in java program to read write data in Oracle database. Is there any sample with key information for me to refer to? Your help will be appreciated.
Jane Jane,
here is a code snippet provided by our QA team
hope it helps
Kuassi
1. Create the table:
"CREATE TABLE rawtable (key VARCHAR2(30), rawcol RAW(2000), longrawcol
LONG RAW, moredata VARCHAR2(100))"
2. Write the data:
byte x[] = {1,2,3,4,5};
byte y[]= {6,7,8,9,10};
PreparedStatement pstmtR =
conn.prepareStatement("INSERT INTO rawtable (key, rawcol,
longrawcol, moredata) VALUES (?, ?)");
pstmtR.setString(1, "rawcol data");
pstmtR.setBytes(2, x);
pstmtR.setNull(3, Types.LONGVARBINARY);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setString(1, "longrawcol data");
pstmtR.setNull(2, Types.BINARY);
pstmtR.setBytes(3, y);
pstmtR.setString(4, "Here's some more data!");
pstmtR.execute();
pstmtR.setRAW(1, RAW_obj) can be used to insert the RAW data.
You can also use setBinaryStream to insert RAW data:
CallableStatement cstmt =
conn.prepareCall ("begin insert into rawtab values (?,?); end;");
cstmt.setBinaryStream (1, (java.io.InputStream) new
ByteArrayInputStream(rawbuf), rawbuf.length);
cstmt.setBinaryStream (2, (java.io.InputStream) new
ByteArrayInputStream(lrawbuf), lrawbuf.length);
3. Read the data:
InputStream is = null;
byte rawbuf [];
byte lrawbuf [];
ResultSet rset = stmt.executeQuery("SELECT rawcol, longrawcol FROM
rawtable");
// You can retrieve the data with the following methods
rawbuf = rset.getBytes(1);
lrawbuf = rset.getBytes(2);
RAW raw1 = rset.getRAW(1);
is = rset.getBinaryStream(column);
is = rset.getAsciiStream(column);
is = rset.getUnicodeStream(column);
When using CallableStatement:
((OracleCallableStatement)cstmt).registerOutParameter(1,
OracleTypes.RAW);

Java Bean scope when used with the JPDK

Portal 3.0.9.8.4 and Jserv
When using JSPs with Java Beans and the JPDK I have noticed problems when setting the scope attribute of the useBean action to something other than "page". For example, <jsp:useBean id="provider" scope="session" class="MyClass" /> causes a java.lang.ClassCastException when there are more than two JSP portlets than attempt to access the ProviderSession object.
Does anyone know what value the JSP scope should be set to when you want the JSPs read/write to the ProviderSession?

The behavior you report is an expected one as your keys of objects on session are not unique to the two portlet instances. Two portlets with the same session object (may have been deployed on the same Portal page), are sharing the same object put on session, thus resulting in thread conflicts. What you need to do is to generate unique keys for objects stored for each portlet instance.
For example, instead of having the id as "provider", you should have it as <portlet instance name> + "provider".
You are not experiencing the same behavior in "request" or "page" scope, as in these scopes, the objects are not shared across portlet instances.
Please let me know if my interpretation of your issue is wrong.

Abhinav

Simple Java Bean Generator use

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.
Message was edited by: Sistiaga Marc

Thanks about your answer.
Without code modifying I wan't to use it with a Maxdb database.
Which driver is ucurrently used ? com.sap.dbtech.jdbc.DriverSapDB ?
Where do i have to launch this script knowing that my J2EE engine is installed in a linux platform ?
My command become :
java -D com.sap.test.DBTest com.sap.dbtech.jdbc.DriverSapDB SAPNW1DB SAPNW1DB CC_ c:\GenerateDB CONFIG_DB
and i always get the response : datasource not found,n driver not specified...
Am I wrong to try this generator in a windows platform where j2ee engine is in a linux platform ??
Thanx a lot in advance !

Navigation Panel using Java Bean Base API

Hi,
I would like to know how do I add the standar navigation panel to my map using the oracle.lbs.mapclient.MapViewer object. I have try different forms which include adding a tile theme layer but its not working. I'm not using the JS API since I want to have an applet.
Thanks in advance.
Susana

Hi,
in MapViewer's web page there is a link to some demos. There you can find a few examples of how to use the Java bean with jsp pages.
If you want to implement a simple java (desktop) application, the following code contains the basic information that you need to start the MapViewer object, set the display parameters, and then add some information to generate a map image. In this example, a base map is used to generate the map.
    String url = "http://localhost:7001/mapviewer/omserver";
    try
      MapViewer mapViewer = new MapViewer(url);     // creates MapViewer object
      mapViewer.setDataSourceName("mvdemo");       // sets the data source (must exist in Mapviewer server)
      mapViewer.setMapTitle("MVDEMO base map");
      mapViewer.setAntiAliasing(true);
      mapViewer.setImageFormat(MapViewer.FORMAT_RAW_COMPRESSED);
      mapViewer.setDeviceSize(new Dimension(600,475));
      mapViewer.setCenterAndSize(-116.65,38.92,19.2);         // sets the map area
      mapViewer.setBaseMapName("DEMO_MAP");
      System.out.println(mapViewer.getMapRequestString());    // this prints the current map request to be issued
      boolean response = mapViewer.run();      // executes the request
      if (response)
          Image img = mapViewer.getGeneratedMapImage();
         // do something with the image in your Java application
    }catch(Exception ex)
       ex.printStackTrace(System.err);
    }The API java doc (see APIs link in MapViewer's web page) contains a more detailed description of the methods that can be used with the Java bean API.

          You realy can do it like Xiang says, but the better way is to use packages. That's
          the way BEA is designed for. If you use packages you can but your bean classes
          in every subfolder beneath Classes. Here for example we have the subfolders test
          and beans:
          You have to declare the package on top of your Bean Source Code:
          package test.beans;
          In your JSP you don't need the import code of Xiang. You only have to refer the
          path of your bean class:
          <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
          There are some other AppServers that only can deploy Java Beans in packages. So
          if you use packages you are always on the right side.

How to make view Java Bean as .ocx file.

Hi All,
I want to use a visual Java Bean in Visual basic. So that I can modify all the bean properties as modify properties in a ocx file.
I used ActiveX Com bridge downloaded from Sun's site. But the packager
makes a .tlb file .
This file can only be added as a reference in visual basic but not as a ActiveX control. Is there any way out to do that???
Thanks & regards.

The packager creates a registry file and a tlb file.
After registering this .reg file, java bean can be used as an ActiveX control.
From within Visal Basic, select the "Tools" menu and "Custom Controls" item and add the Bean control that was generated.
Avinash.

Replace VBX Control with Java Bean

Hi All,
While compiling 6i forms in 10g I got this error of VBX Control (Obsolete)
The document says replace it with JavaBeans.
I don’t know how to replace a VBS Control with Java Bean but this is what I did, I selected the item type as Bean Area.
But the item do have a trigger
begin
control_lib.when_tab_changed(:control.tab_ctl)
end
The Package CONTROL_LIB is coded as below.
Will this code work, technically I think yes, but its always better to ask experts before I move this to test...
package body control_lib is
g_tab_id number := 0
procedure when_tab_changed
(p_tab_id number) is
l_err_txt varchar2(255);
begin
if :system.block_status != 'QUERY' then
if not good_quiet_post(l_err_txt) then
raise form_trigger_failure;
end if
end if
if p_tab_id = 0 then
rpt_ln_lib.new_tab;
elsif p_tab_id = 1 then
stat_lib.new_tab;
elsif p_tab_id = 2 then
per_acc_rl_lib.new_tab;
end if
g_tab_id := p_tab_id
exception
when form_trigger_failure then
:control.tab_ctl := g_tab_id
synchronize
end when_tab_changed
Thanks to all.

A Java bean is another technology than VBX control.
If some document says: Replace it with java bean it certainly means to use a similar java bean with a similar functionality.
I do not know a java bean, which runs VBX controls.
So you surely have to look at what yout VBX does an than to look after a proper java bean (or to write an own one).

Struts, Ant, Weblogic & Java Beans! (whats going on?)

Dear all
Could anyone who can spend some time for me, tell me how I should I go about to use Srtuts, Ant, Java Bean and Web Logic.
I have joined my team newly, couldn�t cope up with the technology they are using.
Basically im struggling to use Ant to build the files for Weblogic. Any help will be of much use for me.
Pls don�t try to give me nose-cut by �go and do google search�.
Ihv done enough of it(dont want to test my PLs patiance), before coming to sun!
Thanks & regards
Vijay

WebLogic datasource may be created in the Administration Console. build.xml script and build.properties are not required.

Need java bean links

Hi
I'm new to the Java Beans concept. I'm going through the documentation for EJB on Sun website, but I feel that it's not complete. I'm searching for some tutorial that expalins how to use Beans in Servlets and JSP pages. Please post some useful links on how to use Java Beans in web applications. Also please suggest some useful books in Java Beans which I can use for reference.
Thanks.

Thanks a lot for the information. But I have a doubt regarding hosting the Java Beans.
I'm using Apache Tomcat 5.0 for my Java Servlets and JSP pages. Can I use the same server to host Java Beans also ?. Or do I have to download the weblogic server separately to put Java Beans in it and then have Tomcat applications access the Beans from weblogic ?.
I can see the latter requires some process to be done, as I'm not familiar with weblogic server. Please advise me.
Thanks.

Problem KeyEvent Java Bean (Francois Degrelle)

Hello !
I have a problem with the KeyEvent Java Bean (keykressed.zip)
from the Forms - PJC and JavaBean store !
1.
I call a forms-dialog and use the KeyEvent Java Bean.
(Set_Custom_Property('BL.BEAN',1,'INIT','')
2.
I call a second forms-dialog and use the KeyEvent Java Bean too.
Set_Custom_Property('BL.BEAN',1,'INIT','')
3.
Now i go back to the first forms-dialog and this dialog hangs...
(No input over keyboard possible !)
Maybe you can help me ?
Many thanks in advance !
Thomas

Hello,
Re-load the JAR file from the article.
I still get an error in the Java console after closing the second dialog, but the key is correctly sent to the first form, so it seems to be OK.

Dynamic Java bean classes for XSD using JAVA (not any external batch or sh)

Hi,
How can we generate dynamic Java bean classes for XSD (dynamically support All XSD at runtime)?
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).
Thanks

Pretty sure you can't. Probably can do a lot of them with years of work.
And can probably can do a resonable subset suitable for the business at hand with only a moderate effort.
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).The Sun jdk, not jre, comes with the java compiler as part of it. You can create in memory class (I believe in memory) based on java code you create.
I believe BCEL alllows the same thing (in memory) but you start with byte codes.
You could just create a dynamic meta data solution as well, via maps and generic methods. Not as fast though.
