I am using Timeseries Chart. It's works fine. But, when I using it in JAVA,some exception occurs.
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperPrintFile.getPath(), paraMap, DBUtil.getConnection());
I listed all the stack trace here. Anyone who knows what's the root cause of this problem? thanks very much.

I am trying to run a project on my tomcat locally, but I get an Exception from the BouncyCastle.
I have checked the path of the key and the keyname, all correct. I have also exchanged the jce policy files. Nevertheless the issue is still there. Any further suggestions?
Here is the entire exception:

We have a simple webapp that is sending a lot of data to our elasticsearch node.
This is how we create the transport client to elasticsearch
TransportClient client = new TransportClient().addTransportAddress(new InetSocketTransportAddress(elasticSearchUrl, 9300));
Everythings go fine and the data is going though until something happens to the elasticsearch node. So, if we shutdown the cluster we get a very nice expected exception

And the whole operation system just get super busy and we have to restart the whole machine. Do you guys have any clue what the problem can be?
EDIT: We are using ES version 0.9.12
We were using elasticsearch 0.90.12 and the java library was 0.90.6. Since we updated the java library to 0.90.12 all the problem disappeared.
I am getting an exception while running GWT.
It says "com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract".
What might be the possible reasons.
Will this happen in all the programs or is it be due to my configuration of the application.
Thanks

It seems some method in your service com.company.cm.ui.client.GroupService.getGroup(java.lang.Integer) threw an IllegalArgumentException. Some assertion fails because it expects some collection to have at least one element.
Did you write com.company.cm.ui.client.GroupService or is it an external lib ?
I am very new to Birt Reports so bear me with this. I am getting
org.eclipse.birt.report.service.api.ReportServiceException: Error happened while running the report.; nested exception is: java.lang.NullPointerException
From some forums I came to know that there is some data source issue with such kind of errors but I am unable to resolve it. Please figure this out, if any one know such error.
here is the stack trace

NOTE
I had Birt 2.3 version, and I am using ubuntu OS.
I have a GWT/GXT application that runs fine via "gwt:run" (hosted mode) but on the Tomcat server it crashes with an JdbcSQLException, which I don't understand because the call leading to the exception is server code that isn't translated to javascript anyways. Also I didn't write the code that causes the exception myself, it is contained in a library that is used by my application.
Can someone tell me how to fix this error?
P.S.: Per request here the code statement that throws the exception:
private Connection conn;
[...]
conn = DriverManager.getConnection("jdbc:h2:"+databaseDirectory+"/"+databaseName+jdbcString, "sa", "");
[...]
PreparedStatement ps=conn.prepareStatement("SELECT * FROM QUERY_CACHE WHERE QUERYHASH=? LIMIT 1"); // throws the exception
