Good afternoon people.
We have a very strange problem here. We have a webservice where many clients connect, and everything was OK until Tuesday when he began to appear the following exception on the console:
javax.xml.ws.WebServiceException: com.ctc.wstx.exc.WstxIOException: null

The exception Caused by: java.net.SocketException: Broken pipe at first think it is a problem with the DB, according to several articles report, but after various tests we did rule out that problem is related to the DB.
The only change in our system was that a customer has to send a larger number of transaction for us, otherwise no change.
Can anyone give us some light on this problem?
Thank you

what could be the cause for it?
and m using apache tomcat.
Caused by: ClientAbortException: java.io.IOException The client has dropped the connection.
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

your error is described in the stack trace
java.lang.ClassNotFoundException: com.hcl.hips.action.KAListproduct
You did not import your class, or somehow failed to wire up it up correctly. Post relevant configs if you want further help.

i do not know whether kiran kumar solved it or not...
But for future people........
I have a GWT 2.3 web app using Objectdb via Rpc. In the embedded mode in eclipse (with Jetty) everything runs fine. When i try to deploy the app on a Tomcat6 Server I get the following Error:

of course the Objectd lib is in the Build Path and the jar file (including com.objectdb.o.RCL.class) is in its place (WEB-INF/lib). Any ideas why Tomcat has problems working with objectdb?
It turned out that this was a permission problem. If you get this error make sure your tomcat can access all necessary files.
