Crystal JRC 2.0 JDBC-OBDC Bridge Issue

I have been using the Crystal JRC version 2.0 since it was released. I have deployed JRC 2.0 in a WebLogic server that currently uses version Java 1.5.0_12 and utilizes the JDBC 3.0 API. We have been asked to upgrade the Weblogic Server to the newest version which uses Java 1.6.0_05. This release of Java now supports the JDBC 4.0 API. I have several reports that were developed using the ODBC driver, so when I deployed the JRC, I used the JDBC-ODBC driver and defined the datasource as follows in the web.xml:
<env-entry>
    <env-entry-name>jdbc/DMPD</env-entry-name>
    <env-entry-value>!sun.jdbc.odbc.JdbcOdbcDriver!jdbc:odbc:mmpd;user=xx;password=xx</env-entry-value>
    <env-entry-type>java.lang.String</env-entry-type>
</env-entry>
This worked fine with Java 1.5.0_12. When I try to run the same reports with the Java 1.6.0_05 driver (sun.jdbc.odbc.JdbcOdbcDriver), I get the database login prompt and I can't get past this prompt. Looks like something has changed with the JDBC 4.0 API, that is not backward compatible with the JDBC 3.0 API.
Any ideas on how to resolve this ?
Also, as a side note, with the JRC 2.0 upgrade, I can't get any error messages to be logged to the cr_jrc.log file which used to be defined in the log4j.properties file. Has the logging interface changed with 2.0 ??
Thanks,
Ken

I am having similar problems. Environment works perfectly in Windows. All JARS and config files moved to AIX UNIX machine. I get nothing more than a Crystal Reports 'Error' on the screen!!!
Any ideas since this was posted??

Com.mysql.jdbc.driver and jdbc:odbc bridge driver

Hi All,
I want to update mysql database from data in hashtable. My application already uses JDBC:OBDC bridge driver for retrieving data from excel sheet and putting in hashtable.
For connecting to mysql i need to use com.mysql.jdbc.driver too in the same code.
How to do that?
my code uses.
Read(String strFilePath,String strFileName)
           filepath = strFilePath;
           filename = strFileName;

Crystal JRC PDF Export Issue

We are experiencing a PDF export issue with Crystal JRC version 12.2.202. The PDF report shows 1 of 3 pages but ONLY the first page is generated. When this occurs, ALL other users that are exporting to PDF experience the same issue with any multiple page report. I can't find any errors in the log that would indicate what the problem is. To resolve the issue, I have to recycle the WebLogic application server that hosts the JRC, which would indicate something gets "locked" in memory and gets cleared when the app server is bounced.
Any ideas on how to resolve this ?

Hi Ted,
Thanks for the response!
Though, the mentioned Sun JVM Bug explains the root-cause, the Bug status also state that it is not fixed yet.
Also, we are reluctant to change the JVM Option to -Xint due to unknown impacts on JVM optimizations.
Is there a patch released for CrystalReports to deal with this behavior? We are using CRJ runtime 11.5.7.620 and seeking for a patch on this version.
Thanks.

Crystal JRC 2.0 Beta Issues

In early December 2008 I downloaded the latest Crystal JRC (crjava-runtime_12.2.0.zip) from the "Beta" website. I am using the DHTML viewer with the ViewReport.jsp and the CrystalReportViewer.jsp JSP components to display my reports. When the report viewer displays, the popups for both the export and the print are not functional. I can dropdown the list of export choices, but cannot select a choice and when I try to print using the ActiveX print control, I get a "communication error" and it locks up. I am currenly using an earlier JRC version that works fine with respect to the print and export popups. However, I am trying to test the new Excel (Data only) export with the new 2.0 version and I am having these issues. I have 2 questions:
1. I tried to find if there was a new beta release available that may fix my isses but it seems the website has been completely redesigned and I can't find the old Beta website to download the JRC. I found a link for Beta Programs but it is just informational and does not provide a download link.
2. Any ideas on what could be causing my viewer issues ?
Thanks,
Ken

Ted,
Yes, I discovered the same thing with the missed URL mapping, however it only solved the print issue. The print works fine now, but the export dialog still acts strange. When I click the export button, the list popup comes up behind the dialog, which acts like a focus issue. Then when I move the dialog box off and expose the list, the list is not functional. It acts like a disabled object and I can't select anything other than leave the default "Crystal Report" option. When I click the export button from the dialog, it does export to Crystal Report successfully, so the export callback does work. I think this is a JavaScript issue, but can't be sure. Interesting thing is, the export functionality worked in the previous beta release (12.0.0.r194) !
Thanks,
Ken

JDBC-ODBC Bridge to SPSS data files - Result Set Type is not supported

Hello,
As mentioned in the subject I am trying to read SPSS data files using the SPSS 32-Bit data driver, ODBC and the JDBC-ODBC Bridge.
Using this SPSS Driver I manged to read the data directly into an MS-SQL Server using:
SELECT [...] FROM
OPENROWSET(''MSDASQL.1'',''DRIVER={SPSS 32-BIT Data Driver (*.sav)};DBQ=' SomePathWhereTheFilesAre';SERVER=NotTheServer'', ''SELECT 'SomeSPSSColumn' FROM "'SomeSPSSFileNameWithoutExt'"'') AS a
This works fine!
Using Access and an ODBC System DNS works for IMPORTING but NOT for LINKING.
It is even possible to read the data using the very slow SPSS API.
However, when it comes to JDBC-ODBC the below code does only work in part. The driver is loaded successfully, but when it comes to transferring data into the resultset object the error
SQLState: null
Result Set Type is not supported
Vendor: 0
occurs.
The official answer from SPSS is to use .Net or to use their implementation with Python in their new version 14.0. But this is obviously not an option when you want to use only Java.
Does anybody have experience with SPSS and JDBC-ODBC??? I have tried the possible ResultSet Types, which I took from:
http://publib.boulder.ibm.com/infocenter/db2luw/v8/index.jsp?topic=/com.ibm.db2.udb.doc/ad/rjvdsprp.htm
and none of them worked.
Thank you in advance for your ideas and input & stay happy!

Thank you for your reply StuDerby!
Actually the above script was before, as you suggested, leaving the ResultSetTeype default. This did not work...
I am getting gray hair with SPSS - in terms of connectivity and "integratebility" none of their solutions offered is sufficient from my point of view.
Variable definitions can only be read by the slow API, data can only be read by Python or Microsoft Products... and if you want to combine both you are in big trouble. I can only assume that this is a company strategy to sell their Dimensions Platform to companies versus having companies developping their applications according to business needs.
Thanks again for any furthur suggestions and I hope, that some SPSS Developper will see this post!
Cheers!!

Null Pointer Exception using JDBC-ODBC bridge on Linux

Wonder if anyone can help me with this one?
I am attempting to use the JDBC-ODBC bridge on Fedora with J2SDK 1.4.2_04, however I am getting a NullPointerException whenever I get the connection. I can get the JDBC connection to work but it is a requirement that ODBC be used.
The code is as simple as it can get.

      catch (Exception e)
           e.printStackTrace();
   public static void main(String[] args)
      doConnection();

The UnsatisfiedLinkError suggests to me that a library cannot be found, but I don't know what library.
As far as I know I have configured ODBC correctly. I can achieve connectivity to my database using other tools and I still get this same error irrespective of whether the DSN is valid or not.
I have installed the unixODBC rpm.
Any help/insite would be greatly appreciated.

JDBC-ODBC Bridge is too slow

Why the Sun JDBC-ODBC Bridge is so slow? When i use the ms bridge it is as faster than a JDBC connection, but i found a bug on the ms bridge that it returns NULL when the value is a "" (blank)
Anyone how to make sun bridge has a acceptable perfomance?
I am using MySQL 3.23 and tested on Sun JDKs 1.1.8, 1.2, 1.4
My comp is a K6-2 400 with 128 RAM
Thanks

isjm said
   I've found using a pure JDBC driver (ashna's JTurbo) to be
   roughly 40% faster than the bridge after doing some
   (admitidly) small amount of bench testing. I also found
   it resolved a number of issues (bugs??) with the bridge
   (e.g. no longer throws an occasional fractional truncation
   exception when inserting timestamps). As for the bridge
   being used only for test purposes check out this URL:
   http://java.sun.com/J2se/1.3.0/docs/guide/jdbc/getstart/bridge.doc.html
   They recommend using the bridge only for experimental use or when a
   pure driver is not available. I guess you could consider this as test purposes only.There is no such thing as a 'pure driver' (or 'pure jdbc driver' from a different post.)
The doc you site suggests a 'pure java' driver - a type 4. I question that. I know there are number of things that one can do in ODBC and in OCI which speed up requests. And obviously one can't do those in java.
Performance problems are caused by the following:
-Requirements-most impact
-Design
-Environment (cpu,network,thread, etc bottlenecks)
-Language/intefaces - least impact.
Changing requirements/design can easily produce impacts of orders of magnitude (by removing one requirement I reduce a 4-8 hour report to less than 30 seconds.) So how much impact did the 40% you saw impact your total application? Did you profile your application/system under load using a automated tool to measure the speed?
I would suspect also that the suggestion that the driver is 'experimental use or when no other alternative is available' might be slightly biased as the driver was produced by Merant who is actively selling drivers too. One would suppose that they were not allowed to deliberately introduce bugs into the code. However, they might have insisted that some language be introduced to suggest that someone should buy the product.

   But i can't believe i've tested today again and the sun
   bridge is working as fast the ms bridge! i can't
   understand, yesterday i've tested a million times
   and it was about 30 times slower, i'll try to find
   what's happened yesterdayDid you use a closed network? Did you use isolated servers?

To run a report from command line, when using jdbc-odbc bridge

Hi,
How to run a report from command line, when using jdbc-odbc bridge?
Usually with tns, we do by "rwrun module=<> userid=<user>/<passwd>@tns".
with odbc, we do by "rwrun module=<> userid=<user>/<passwd>@odbc:DSN"
Please specify, what is command line arguments for jdbc-odbc bridge driver?
Environment : Oracle 9i Report Builder on WinNT
Database : Sybase
Regards,
Ramanan

Hello Ramanan,
Report Builder : connect JDBC Query in Report Builder is to through Connection Dialog in JDBC Query Editor. User can use a Sign on parameter (can use, default : P_JDBCPDS or can create new) to connect to JDBC Data Source. Connection once made will be mentioned and will be reused through out Reports Builder.
JDBC PDS allows user to connect one or more same or different kind of databases.
While running report through runtime or Server, user can pass the sign on parameter(connection string) value, like any other user parameter.
Syntax for connection string : <username>/<password>@databaseURL . The syntax of database part of connection string depend on the type of JDBC Driver used to connect to Data Source while designing the JDBC Query. databaseURL refer to the location of the database and its format depend on the JDBCPDS river selected in design time while creating the JDBC Query.
rwrun eg :
rwrun report=jdbc_odbc.rdf destype=file desname=output.html desformat=html P_JDBCPDS=scott/tiger@database
Server eg :
http://server.com:8888/servlet/RWServlet?server=MyReportServer+report=jdbc_odbc.rdf+destype=cache+desformat=html+P_JDBCPDS=scott/tiger@database

Oracle RDB Driver fails with JDBC/ODBC Bridge

Has anyone experienced problems using the latest Oracle RDB
Driver (3.0.2.0) with the JDBC/ODBC Bridge.
We have been using the Oracle ODBC Driver for RDB (2.10.17)
successfully on NT, but it is not supported on W2K. The new
drivers work fine for Access etc., but fail with the bridge.
Specifically, you can step thru a result set, but getObject()
returns null for all fields.
Any suggestions?

JDBC-ODBC bridge

Hello,
I'm using JDK1.5 and have a working connection to MySQL using JDBC. I now need to connect to Interbase database using ODBC and that's where I'm completely lost.
Could somebody please tell me if I have to download a JDBC-ODBC bridge or if it's already in the package? Can JDBC-ODBC communicate with InterBase?
Please help.
Thank you,
Victor.

Uf you want the password stored in the ODBC DSN, you'll need to go through the back door. This isn't something Oracle makes easy because it has horrible security implications-- the password will be stroed in the registry in plain text.
If you add a key "Password" with the value of your password to the registry where your DSN is, the ODBC driver will use that value to connect to the database. I don't recall the exact heirarchchy riht now, but a registry search for the name of your DSN ought to find it pretty quickly. As always, playing with your registry isn't recommended and may cause problems if you don't do it correctly.

Problem using Jdbc-Odbc Bridge

Hi,
I am using Java 2 SDK and I am trying to access MS Access database on my machine using Jdbc-Odbc bridge. I have set up the DSN in ODBC. But I get the following error when I run my program -
'No Suitable Driver'
Here's my code snippet-
Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver");
String dsn = "jdbc:odbc:DriverInfoDB";
Connection con = DriverManager.getConnection(dsn,"","");
con.setAutoCommit(false);
Statement stmt;
String query = null; // SQL select string
ResultSet rs; // SQL query results
stmt = con.createStatement();
.....etc etc...
Where is the error in this code??
Help Needed!!
Thanks
Vivek.

try
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection con = DriverManager.getConnection(dsn,"guest","guest");
OR DriverManager.getConnection(dsn);
System.out.println("Conection's opened");
catch(ClassNotFoundException cnfe)
System.err.println(cnfe);
catch(SQLException sqle)
System.err.println(sqle);
try that code and double check you DSN Name . it's a good practice to greate a system DSN.

JDBC-ODBC Bridge Performance To MS Access

Hey all, I'm running a Java app that extracts an entire table (set of tables) from Oracle and copies them into Access. The easiest implementation has been to use a DSN-less Type 1 JDBC-ODBC bridge connection to Access, but unfortunately the inserts are taking too long.
I have tried both Statement and PreparedStatement approaches, with both single row and batch updates. Some of the performance times, relative to the computer I am on (PIII 1 gHz with 256 RAM), are as follows:
Via Batch, about 8min, 15 seconds per 10,000 rows.
Via Single Row updates/inserts, about 52 minutes for 45,000 rows.
I've tried alot of varieties with batch, but 10,000 seemed to be the best. The largest table is only 45,000 rows (right now), but has the potential to grow much larger (obviously). This application needs to backup 4 databases, each with N tables (current N=7, but will expand). I'm trying to knock down the times and increase performance, but am not sure what is "reasonable" for Type 1 connections with JDBC. I've seen third party drivers, Type 3, for Access...but don't want to run the middle tier server for filtering request through. I'd rather use Type 4, but can't seem to find any for Access.
Any suggestions? Recommendations? Let me know! Thanks all! :)

Hi,
If its a backup/batch process why are you worrying about performance, its only an offline process :) even if has to be triggered during an OLTP run this task asynchronously.
I dont know why you have chosen java to do this ??? any way prepared statements with non scrollable resultsets will increase you performance better tha scrollable normal statements.

About JDBC ODBC bridge

I'm developing an application using EJBs in a development environment with Sun Application Server, Sql Server and NetBeans IDE 4.1. I'm using entity beans and session beans in my application. But, when I try to connect to database using a Servlet or JSP with the session beans, the connection with database could not be established. This is my problem!!!

First, you probably shouldn't use the JDBC/ODBC bridge. Any serious and many non-serious databases have real drivers. Is there anything but Access that really needs the bridge...? Use the jTds driver (google for it). Or just last week Microsoft beta'ed a new JDBC driver for MSSQL; no idea how good it is. Some smalltalk on that: http://www.theserverside.com/news/thread.tss?thread_id=35063
Second, what error do you get?
If it is "connection refused", here is my standard first aid check list:
- Check host name in connect string.
- Check port number in connect string.
- Try numeric IP address of server host in connect string, in case name server is hosed.
- Are there any firewalls between client and server blocking the port.
- Check that the db server is running.
- Check that the db server is listening to the port. On the server, try: "telnet localhost the-port-number". Or "netstat -an", there should be a listening entry for the port.
- Try "telnet serverhost the-port-number" from the client, to see if firewalls are blocking it.
- If "telnet" fails: try it with the numeric ip address.
- If "telnet" fails: does it fail immediately or after an obvious timeout? How long is the timeout?
- Does the server respond to "ping serverhost" or "telnet serverhost" or "ssh serverhost"?
