DB access in JSP ignored

Question

<p>Hi everybody</p><p>I created a report in Eclipse against a local MySQL, embedded it in a JSP and deployed it on a local Tomcat for testing. Evrything went smooth but when I reasign an identical remote DB to the report, copy the Web Archive onto a remote JBoss, the DB connection fails (MySQL 1045). </p><p>I assumed that the DB URL is kept inside the report (.rpt) file and that username and password have to be set in the JSP like so:</p><p>         IConnectionInfo connInfo1 = new ConnectionInfo();<br />        connInfo1.setUserName(Utilities.DB_USER);<br />        connInfo1.setPassword(Utilities.DB_PASSOWRD);<br />        connInfos.add(connInfo1);</p><p>       [...]<br />          //Create Viewer<br />        CrystalReportViewer viewer = new CrystalReportViewer();<br />        viewer.setReportSource(reportSource);<br />        viewer.setEnableLogonPrompt(false);  <br />        viewer.setDatabaseLogonInfos(connInfos);</p><p>If I use the remote DB from the local Tomcat it works too.<br /></p><p>Any help is highly appreciated.</p><p>Thanks in advance and regards from Zurich, Switzerland</p><p>Peter </p>

<p>ok, I found a code snippet that allows to change database access from within a JSP page:<br /></p><p>        //Create Report<br />        ReportClientDocument reportClientDoc = new ReportClientDocument();<br />        String report = gerlingUser.getReportName();<br />        reportClientDoc.open(report, 0);<br />        reportSource = reportClientDoc.getReportSource();<br />        session.setAttribute("reportSource", reportSource);<br />        <br />        <br />        // ****** BEGIN CHANGE DATASOURCE SNIPPET ****************  <br />            {<br />                String connectString = "jdbc:mysql://192.168.1.11:3306/DBNAME";<br />                String driverName = "com.mysql.jdbc.Driver";<br />                String JNDIName = "nameDS";<br />                String userName = "username";<br />                String password = "userpassword";            <br />                // Switch all tables on the main report and sub reports<br />                JRCHelperSample.changeDataSource(reportClientDoc, userName, password, connectString, driverName, JNDIName);<br />            }<br />            // ****** END CHANGE DATASOURCE SNIPPET ****************     <br />        <br /><br /></p>
