Java bean connectivity -

Hi,
There are some issues while I am using webservice connection from crystal report.(I am using webservice with ws security but my cr doesn't support this. This create problem while I am calling cr from my java application).
I tried Java bean connectivity .. but facing some problems - I would like to write a java bean which will retrieve data from my webservice and need to return to cr. Webservice return data as "soap xml", how can I convert this to resultset. Can I add my data directly to the xml before passing to the cr? Or can I use any other return type from my java bean.
Could I provide a struts application url(action url) as a datasorce to the cr? If so how can I achieve this and what should be the return type. Please advise the better datasource connection to resolve this issue?
I want to call the report from java application and need to deploy the same in the Crystal enterprise server
Thanks in advance
Thomas

Please re-post if this is still an issue or purchase a case and have a dedicated support engineer work with your directly

Crystal report Java Beans Connectivity

Hi
My name is Bach Ong. I.m currently migrating Crystal reports 10 to Crystal reports 2008 using Java Beans Connectivity. Using ResultSet as dataset. all results are return alright, EXCEPT for string type fields. The data for STRING type fields are some how suppressed. But if i executed the beans within eclipse the the string field is populated with data.
can someone assist me with this issue.
Thanks
Bach Ong

Some suggestions I would give for this are:
1. It may be a fault with the data itself. Specifically, if you have a string field that contains invalid or null data (Instead of an empty string), it may be causing an error to be thrown when the report engine tries to process the string fields - and it thus fails on all string fields.
So please try this with some data where all fields contain valid non-null, non-empty data and see if it works.
2. One of the difficulties with javabeans is that they don't give proper error messages. However, there is a way to kick off the javabean java process in the crystal report designer which allows you to debug your javabean inside the report designer. I have attached a sample that shows how to do that - and that should get you the real error message of what is going wrong.
Note: Due to the way these forums work - it will only let me attach a file if it is named with the .txt extension. You will need to extract the txt file and then rename it to .zip (annoying I know).

Java Bean Connectivity and Closing Connections (XI 3.0)

Hi guys,
We have existing Java Beans that we would like to use with Crystal Reports. Our current Java beans return a disconnected GridModel and explicitly close the connection immediately after so that they can be returned to the connection pool (Oracle).
Once we modified these beans to return ResultSets we found that closing the connection also closes all the associated ResultSets and Statements.
What is the best practice here?
Modify the Java bean to close the connection in the finally block?
Will Crystal clean up after itself?
I also see there is something called a CachedRowSet which is disconnected:
http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/rowset/CachedRowSet.html
Is this supported by Crystal?
Thanks,
Kevin D Lee =)

Hello Kevin,
Enterprise XI 3.0 CRConfig.xml points to Java JRE 1.5 provided with the install, so you should be ok with the CachedRowSet.
It's used by other customers for disconnected operation.
Since you're going to Oracle, you'd likely encounter issues mapping Oracle fields to POJO property types.
Furthermore, POJO Factory libraries that were shipped with Crystal Reports XI Release 2 aren't shipped with Enterprise XI 3.0, so you'd not find that an out-of-the-box option.
Another alternative to CachedRowSet is to define callback method in your JavaBeans class that Crystal will call when it's done with the data source.
This has been implemented in XI 3.0 (track ADAPT00877915) - excerpt from the track note:
<JavaBeans>
    <CacheRowSetSize>100</CacheRowSetSize>
     <JavaBeansClassPath>c:\javabeans\</JavaBeansClassPath>
     <CallBackFunction>CrystalReportsLogoff</CallBackFunction>
</JavaBeans>
      Customer can configuration the <CallBackFunction/> to let CR know
      which function should be invoked when loging off.
Advantage of CachedRowSet is that you can immediately close it after you've read all the data, disadvantage would be the default implementation stores all data in memory.
Advantage of the callback method is that it would use the JavaBean you've supplied (and not load all data immediately in memory), but callback won't be called immediately, but only after the report is done with.
Sincerely,
Ted Ueda

Problems with Java-Beans-Connectivity

CA Forum: JAVA
I'm new in crystal reports and try to connect a sample bean class to the java beans conectivity. Problem is that i only get JavaServerType=JavaBeans|JavaBeanName= for selection. Can anyone tell me what the problem is with my configuration. I followed the steps of the POJOTutorial.doc and the Configuration-Infos of the java_beans_connectivity.My System is w2k professional and for Crystal Reports i use the developer installation with Product Version 11.5.0.313 Thanks by now

Java Connectivity - No classes appearing in the Java Beans Classes dropdown

Hi,
VERY NEW user to Crystal Reports. I am trying to create a report using a java class as a datasource. I have updated the setting in the CRConfig.xml file, and can get the Java Beans Connectivity screen to appear, but is shows none of my classes in the dropdown. I found a knowlege base entry that indicated this problem was caused by the JavaBeansClassPath value in the CRConfig.xml file being invalid. But I've verified the location and it is pathed directly to the classes.
Not sure what I am missing, but any help is greatly appreciated.
Thanks!

Ted,
Thanks for the reply. I checked out each of your suggestions, but haven't had any luck thus far. Here's what I found:
1. We created a simple method in an existing public class to return a ResultSet. The method looks like this:
public ResultSet GetAllMediaTypesRS()
      String strFuncName = "ScsXDMDatabase::GetAllMediaTypesRS : ";
      ScsDebug coutDebug = new ScsDebug();
      String strSqlStmt;
      String strMediaType;
      ScsStringList sslReturnList = new ScsStringList();
      // Create the SQL to get all the Displayable Media Types.
      strSqlStmt =
         "SELECT DISTINCT mt.Media_Type_Name "
            + "FROM dbo.Media_Type mt "
            + "WHERE mt.Media_Type_Rqst_Display_Ind = 1 "
            + "ORDER BY mt.Media_Type_Name";
      coutDebug.println(strFuncName + "SQL Statement: " + strSqlStmt);
      // Run the Query
      Statement stmt = null;
      ResultSet SQLResult = null;
      try
         stmt = GetConnection().createStatement();
         SQLResult = stmt.executeQuery(strSqlStmt);
      } //End of Try
      catch (SQLException sqle)
         if (sqle.getErrorCode() != 0)
            coutDebug.println(
               "Error in ExecuteQuery: "
                  + "Error code - "
                  + sqle.getErrorCode());
            coutDebug.println("Message - " + sqle.getMessage());
      return SQLResult;
The signature, and the method look fine to us, but maybe we are missing something obvious.
2. We do use JDK 1.5 to compile the classes, but my JavaDir setting in the CRConfig.xml file points to jre1.6.0_02. I assume this is OK.
3. We do see java.exe start up when opening the JavaBeans connection.
4. No firewall issues as we are inside our corporate network.
Any other thoughts or ideas? I did see a knowledge base entry that indicated the cause of this particular problem is that the JavaBeansClassPath in CRConfig.xml is incorrect or invalid. I've validated the path takes me right to the classes, so I believe that is OK. Is there some way that we can see the actual path that is searched when the JavaBeans connection is opened?
Thanks for your help.

Running java bean from forms9i on win xp

hi all,
I have a form that uses java bean to write txt file on client computer. java bean connects to database and uses it's data to create txt file. everything runs fine on client with win2000, but with windows xp (professional, sp2, ie6.0) there seems to be some problem with connecting to db (returned connection is null). my win xp firewall is turned off, security settings (including java and activeX) are low, forms version is 9.0.4.0.19. java code seems to be ok, i think it has something to do with forms/xp compatibility. has anyone had similar problem?
Thanks for any response,
Albert

Thanks for your response. First version of our program was running on webutil, but as it turned out it was lacking performance. New version, with our custom java bean is much faster.
As I wrote it works on Windows 2000. It also works on WinXP as a standalone application. Only when deployed to Oracle Forms with XP client it fails. Error occures during retreiving connection to db when calling DriverManager.getConnection method. No exception is thrown, retreived connection is null.
Thanks for any help

Crystal Reports data connection using Java beans

Hi
My name is Bach Ong, i'm currently perform re-configuring Crystal reports 2008 to connect via
Java bean to Jboss server, this uses look up service on JBoss server. The connection is using Connect
look up using the properties:
java.naming.provider.url=jnp://emgsydapp121:10499
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
for file CRConfig.xml i put as follows:
<JDBCURL></JDBCURL>

Hi Don Thanks for the reply.
I've was able to connect via Java beans and JNDI. But this one is going the JNDI of JBoss sever, which the JNDI already configure and working for Crystal reports v10.

Hello Sir,
I have a simple Issue but It is not resolve by me i.e input parameter
are not store in Ms-Access.
I store the input parameter through Standard Action <jsp:useBean>.

An error in jsp page useBean when i try to include the java bean package?

Hi Sir,
I am using import com.project.ShowData in java beans inorder to connect to the jsp.
The jsp code goes like this:-
<%@ page import="com.project.ShowData" %>
<jsp:useBean id="jspuser1" class="com.viman.ShowData" scope="session"/>
<jsp:setProperty name="jspuser1" property="*"/>
Here the error is showing as cannot resolve symbols in com.project.ShowData.But i have given the same in java beans like this:-
Package com.project;
//import of package goes here
public class ShowData
//code goes here
It seems that all are correct here.I have done few programs using this without any problem.But suddenly it is giving a problem like this.What is the problem here?It is quite Urgent.Thank u.
Regards,
m.ananthu

Column Not found error while trying to access databse through JSP+Java Bean

I am trying to acees MS Access 2003 db through JSP using Tomcat 5.0.28.The code for accessing the databse is incorporated in the bean.The jsp only calls the particular method of the bean .
Code for Java Bean:
package ActiveViewer;
import java.sql.*;
import java.util.*;
public class CompanyBean
Connection con;
ResultSet rs=null;
Statement st;
     public CompanyBean(){}
     public void connect()
     try
     Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
System.out.println("Here4");
con=DriverManager.getConnection("jdbc:odbc:activeviewer","","");
     System.out.println("Here1");
     catch (ClassNotFoundException e)
     System.out.println("Could not locate driver.");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
     catch (Exception e)
System.out.println("An unknown Exception has occured :: "+e);
     e.printStackTrace();
public void disconnect()
     try
     if (con!=null)
con.close();
     catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
public ResultSet select(String username)
if(con!=null)
     try
st=con.createStatement();
     rs=st.executeQuery("select * from company where username='" + username + "'");
catch (SQLException e)
System.out.println("An SQL Exception has occured :: "+e);
     e.printStackTrace();
catch (Exception e)
System.out.println("An Exception has occured while retrieving :: "+e);
e.printStackTrace();
else
System.out.println("Connection to database was lost.");
return rs;
The code for JSP that uses the above bean is:
<%@ page language="java" import="java.sql.*,ActiveViewer.* " contentType="text/html"%>
<jsp:useBean id="conn" scope="session" class="ActiveViewer.CompanyBean" />
<html>
<body>
<% String username=request.getParameter("username");
String password=request.getParameter("password");
System.out.println("username:"+username);
System.out.println("password:"+password);
conn.connect();
ResultSet rs=conn.select(username);
System.out.println("Below select ");
while (rs.next())
String dbusername=rs.getString("username");
     String dbpassword=rs.getString("password");
     if(dbusername.equals(username) && dbpassword.equals (password))
{ %> out.println("OK");
          <% }
else { %>Invalid Username and / or Password.
<br>Clickhere to go back to Login Page.
<% }
} %>
</body>
</html>
I get the following error:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
javax.servlet.ServletException: Column not found
though the database is not int he same folder as the jsp, the DSN is set correctly to pint to the db location.The jsp does print in stdout file:
Here4 (from connect method above)
Here 1 (from connect method above)
Below Select (from jsp)
This means that the jsp does connect to db but it gives the above error.Also the field name also matches that in the database and data is present in the db too.
All other things like creating package for bean,incorporating the packakage are done.
Can someone please help me with their precious advice?

U're getting this error because there is no field called 'password' in ur database, the field in ur database is named 'cpassword' and not 'password'. So change the statement rs.getString("password"); to rs.getString("cpassword");

Beans connectivity fails in CR Developer

Hi,
I hope this is the right place to ask. We are currently testing CR 12 with Java beans as a data source, but somehow it won't work. I did set up the Java connectivity like it was described in "crxi_java_bean_connectivity.pdf", i.e. set the classpath and created a class that provides a java.sql.ResultSet from a static method.
When I try to add the bean connectivity in CR Developer by entering "com.example.sub.pckg.MyClass" in the wizard, CR adds the class as a data source but it doesn't find the ResultSet providing method.
Removing the package/path yields the following error:
Failed to open the connection. Details: Unexpected error
Logon failed.
And it doesn't show the name of my connector class in the dropdown box of the wizard in the first place. What may have been gone wrong? Perhaps it's a bug? Any help is appreciated.
Kind regards, P. Müller.

I've seen this sometimes happen if there are other classes in the javabeans classpath folder that do not involve returning back resultsets. What appears to happen is that Crystal Reports goes through all the jars / classes in that folder, and if it runs into something it doesn't understand, it doesn't process the rest of them (This is what appears to happen).
The solution has been to remove all other classes and jars except for the specific class that returns back the resultset.

How to pass a internal table into Java Bean

Hi Experts,
I created a JSPDyn page to display Sales orders form R/3 using bapi_sales_order_getlist.
I used JCO to establish connectivity between JSP Dynpage and R/3. I executed the bapi successfully, i want to move the sales orders retrieved from the Bapi to a Java Bean. So that i can use the bean to populate the value as a table.
with regards,
James.
Valuable answers will be rewarded.....

Hi Bala,
If you want to pass this internal table between different methods of the same view then write the contents of this internal table to a context node of your view using BIND_TABLE. You can then read the contents of this internal table from the other method using the reference of that node & the GET_STATIC_ATTRIBUTES_TABLE method.
However if you want to pass the internal table between methods of different views then create a context node at the COMPONENTCONTROLLER level & then do a context mapping of this node to your local views context in both your views. You can follow the same BIND_TABLE & GET_STATIC_ATTRIBUTES_TABLE methods approach.

Request parameter are not stored in database through Java Bean

Hi,
I want to store the request parameter in database through Java Bean.Allthough program are properly run but value are not store in DB.
Here My code:

<% obj.show();%>
<%
out.println("Ur data is saved in DB");
%>Please Help me.
Thanks.

The issue is in the naming of your fields.
Change User -> user and Pass->pass
Name: <input type="text" name="user">
Password: <input type="password" name="pass">

"Java-Bean: True" missing after being packed in jar file

Hi All
X86, Windows XP Professional, J2SDK 1.4.2
I complied a section of code ", which is from << Thinking In Java>>(3rd).
Created a manifest file "BangBean.tmp"
<<
Name: bangbean/BangBean.class
Java-Bean: True
>>
And then packed class files into "BangBean.jar" with command
"jar cfm BangBean.jar Bang BangBean.tmp bangbean".
It's puzzling that "Java-Bean: Ture" was missing in the "BangBean.jar/META-INF/MENIFEST.MF" .
<<
Manifest-Version: 1.0
Created-By: 1.4.2 (Sun Microsystems Inc.)
Name: bangbean/BangBean.class
>>
What's more, after altering the"BangBean.tmp" into this
<<
Java-Bean: True
Name: bangbean/BangBean.class
>>
and had a another try.
I got a jar file with such MENIFEST.MF.
<<
Manifest-Version: 1.0
Created-By: 1.4.2 (Sun Microsystems Inc.)
Java-Bean: True
Name: bangbean/BangBean.class
>>
This jar file worked well in BDK's beanbox.
I've test it with JSDK 1.5.0, the same thing happened.
And I didn't encounter such problem in other bean programs.
I've searched " 'Java-Bean: True' missing " with google, but didn't get proper answers.
Is there anybody who can give a prompt about why this happend?
Thanks a lot for your help!

Since you didn't use code-formatting tags ([ code ] and [ /code ] without the spaces) it's kinda hard to look at it. But I'm sure it DID execute much more than just the return statement - maybe you're not closing a file or db connection, or maybe you're seeing a cached page, so it actually isn't executing ANYTHING on the server (is your browser set to never check for newer pages so it (almost) always returns from cache, for example?)
