BO SDK Crystal Report

BO SDK Crystal Report

BO SDK Crystal Report

Hello All,

I am new to this group . I am presently working on BO SDK which uses crystal report(*.rpt ).
The BO team here creates a report and give us the *.rpt file which we export to pdf or csv.The report fetches data from DB. The BO team is saying that the report connects to DB and execute query just we have to pass parameters.
I am setting parameters to my report but it is not working saying ReportSDKException
Error finding JNDI name (DNY08600)---- Error code:-2147467259 Error code name:failed

int x = byteArrayInputStream.read(byteArray, 0,
byteArrayOutputStream.write(byteArray, 0, x);
// Close streams.
} catch (IOException e) {

public static void main(String[] args) {

but when I am creating the connection and adding below lines before passing parameters it is working fine :

for (int i = 0; i < dbTables.size(); i++) {

String tableAlias = reportClientDoc.getDatabaseController()

System.out.println("oldAlias 1111 >>>>>"
+ dbTables.getTable(i).getName());

//String qu1 = ""
String query = "select * from " + dbTables.getTable(i).getName();
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery(query);

results.put(tableAlias, rs);


// Setting the DataSource in Report
final Enumeration<String> aliasEnumeration = Collections
while (aliasEnumeration.hasMoreElements()) {
String oldAlias = aliasEnumeration.nextElement();
System.out.println("oldAlias >>>>>" + oldAlias);
ResultSet rs = results.get(oldAlias);

I just need to Ask if BO people is creating connection and executing query why I have to set result set to report datasource.

RE: BO SDK Crystal Report

I haven't worked in the Java SDK for this, but I have extensive experience in the .NET SDK which is similar. In your original code, I don't see that you set the database logon anywhere. That could be what's causing your problem. In a ReportDocument in .NET I have to go to each of the DataSourceConnections and call SetConnection to set the logon for the database.

RE: BO SDK Crystal Report

Actually I have taken connection and my question is different . Suppose I have a query which pulls data from 5 tables then
I have to call reportClientDoc.getDatabaseController().setDataSource(rs,oldAlias,oldAlias+"_rs") five time with 5 hits to database which is not something good for performance.

I just need to know how are you writing code when you have to pull data from 5 different tables.

RE: BO SDK Crystal Report

Usually when I'm using the Crystal SDK, I load the data into an in-memory dataset in my project and connect the report to that instead of to the database directly. That way I have more granular control over how the SQL runs. I'm not sure how to do that with Java, though.

Are you sure that each call to setDataSource is doing a separate log-in to the database? Based on how thinks work in the Crystal designer, I think it may connect with the first call and then for each successive call check to see whether that connection has already been made prior to trying to connect again.

RE: BO SDK Crystal Report

You are right connection is done only once but the SQL Query is fired in loop based on the number of tables.
Are you keeping your report file locally or keeping it in the enterprise server

RE: BO SDK Crystal Report

Ahh, I think I know what's going on - Turn off "Verify on First Refresh" for your report. It's on the File|Report Options menu. The 5 queries are the report verifying that all of the tables have the same data structure as when the report was created.
