SQLException at SDM deploy: closed connection

Hi,
we are using JDI to develop and deploy a webdynpro application.
After having deployed on the production system we have developed a patch and tries to deploy it as well, but get an java.sql.SQLException (Closed Connection) from the SDM:
We also looked at oracle logs, application logs and stack traces, but did not find any further information.
SDM log:

SQLException: Closed Connection, SQL state [null]; error code [17002]

Hello All,
I am supporting a Java 5 project on Tomcat. We've used Spring and Stored Procedure in the project.
Recently we deployed our application in a GoLive environment and have started seeing Timeout errors in log files. After around two days we also have to restart Tomcat as users are no more able to login to access the application.
Same application runs fine without any timeout issues on another environment.
The only difference between two environments is that the Go-Live env has a firewall between Tomcat and Database and the other environment hosts both Tomcat and Database on same machine (i.e. no firewall).
For GoLive env the only port open on firewall for JDBC connection is 1521 and is used in the connection string url for obtaining the connections.
When there is a Timeout error, the N/w admin guy observed that the JDBC connection was not attempted on 1521 port, but on some random port which is not open on firewall, due to which the Database server logs also do not show entry for this connection attempt as it gets blocked by the firewall.
I am not sure why a randam port should be used to connect when a specific port is mentioned in the connection url? Also what can be making this port switching?
Application uses Apache DBCP with Spring to obtain connections.
Has anyone experienced similar errors?
Any suggestions/help on this issue is greatly appreciated!
Many Thanks,
CD

Java.sql.SQLException: Closed Connection error when invoking web service

Hi
I've assembled a simple web service for an Oracle PL/SQL package and deployed it on a Standalone OC4J, when I come to invoke it on the Oracle Enterprise Manager screen I'm getting the following returned within the envelope body:
<env:Body>
<env:Fault>
<faultcode>env:Server</faultcode>
<faultstring>Internal Server Error (serialization error: java.sql.SQLException: java.sql.SQLException: Closed Connection)</faultstring>
</env:Fault>
</env:Body>
The function that is called within the database returns a user defined object that consists of a RAW value and an XMLTYPE. The function takes a string as a parameter, when I enter a string that I know will not return an object there is no error in the envelope body, only when there is an object to return does the error appear.
Anyone have any suggestion as to why this is?

I'm no further forward with this: has anyone assembled, deployed and invoked a web service that returns a XMLTYPE?? I know this should be possible but I think there's maybe some manual intervention required with the classes created with webservicesassembler: I'd really appreciate it if anyone with any experience of this kind of thing could help me think this through.

PLSQL webservice eventually gives java.sql.SQLException: Closed Connection

Hi
We have created a web service based on a plsql procedure in jdeveloper 10.1.2.1.0
We deployed the web service to .ear file in jdev and then deployed that ear file to our 10.1.2 app server.
The web service works fine for a short time but then gives
java.sql.SQLException: Closed Connection
The web service is not used frequently so it's possible the connection is timing out. I haven't tested invoking the web service perodically to see if it remains alive.
I tried to follow this note on metalink
https://metalink.oracle.com/metalink/plsql/f?p=130:14:2526430465590485698::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,370209.1,1,1,1,helvetica
Which wants me to make changes to the file <webservice_name>Base.java in our case GPAuditBase.java
My questions are:
1. In the jdeveloper navigator there is a file called GPAuditBase.sqlj but it does not contain all the code mentioned in the metalink note. Specifically the finally{} section. Do I need to edit the generated GPAuditBase.java that is saved in the src folder for the project? That file seems to contain the code mentioned in the metalink note.
2. If so, how are those changes reflected in the ear file that I want to deploy to my app server? Do I change the files in the src folder and then deploy to ear in jdev
thanks

Java.sql.SQLException: can't create statement from closed connection

java.sql.SQLException: can't create statement from closed connection.
at com.caucho.sql.QPooledConnectionImpl.prepareStatement(QPooledConnecti onImpl.java:411)
I am getting this error with my JSP's, i am running on Resin on Win2k, and MySql as backend.
Has anyone else also faced this issue ?
Looking for someone to help me to solve this issue.

Looking for someone to help me to solve this issue.Maybe you are closing the connections. You might want to verify that you are not doing that. Or if you are that that is the correct way to return the connection to the pool.
Or you could have stale connections. Some databases will time out connections if the connection is no used in a while. (This is a good thing.) But this means connection pools must do something with connections that are not used for a while. The pools usually have a configuration option(s) which allows you to set up a keep alive message which keeps the database from closing the connection.

Java.sql.SQLException: Closed Connection from Custom Identity Service

Hi,
Here is an issue I am trying to resolve:
Platform: Oracle BPEL 10.1.2
OS: Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
Please note that the whole thing has been working in other same type of installations (e.g. RedHat, Windows, Developer BPEL on Windows & Linux) but this seems to be something special on this server. Any help will be appreciated:
This actually work for sometime (2-3 hours) and then suddenly stops working even if we don't do any transaction on it.
Thanks,
Bipul Dutta.

I have my application jar on the server, and launch this JFrame application from the browser. ><zen question>
Which particular 'the browser'? What version of what browser running on what OS?
</zen question>
The reason I ask is that it is up to the browser to call an applet's stop()/destroy() methods and if they do not do so - there is almost nothing we as developers can do about it.
If you need such reliable shut down behaviour, it would be best to launch the applet or frame using Java Web Start.

Java.sql.SQLException: Closed Connection: next

java.sql.SQLException: Closed Connection: next
Here's the JDBC SELECT code:
Class.forName(driver);
con = DriverManager.getConnection(url, user, password);
stmt = con.createStatement();
rs = stmt.executeQuery(select_query);
while(rs.next()) /*Exception occurs on this line! */
Here's what I know:
I can connect to the instance using TORA ok.
The SQL query returns rows from TORA.
I believe the connections are ok because if I purposely mess up the syntax, I get back ORA-errors.
I can execute an INSERT statement ok from a servlet.
I'm using the classes12.zip drivers from the oracle jdbc installation directory.
I'm using the default JDK in WSAD 5.1
Thank you all for helping!
Ryan
[email protected]

Ryan,
I'm only guessing, but I don't think that:
DriverManager.getConnection(url, user, password);is how to obtain a "Connection" object when using WSAD ("WebSphere", right?) -- even though I don't use WSAD, myself.
Is the java code you posted part of a POJO (Plain Old Java Object)? Or a servlet? Or an EJB? Or a JSP?
Remember, error messages can sometimes be misleading.
What Oracle database version are you using?
What platform are you using?
Good Luck,
Avi.

Java.sql.SQLException: No operations allowed after connection closed

Hi all
I was trying the jakarta DBCP pool for managing my connections to Mysql(4.0.17-standard ). I let tomcat to manage the pool by specifying datasource in server.xml and web.xml. Everything works fine if there are only a few transactions. But when the number of queries increse, I get an exception like
java.sql.SQLException: No operations allowed after connection closed.
Connection was closed explicitly by the application at the following location:
** BEGIN NESTED EXCEPTION **
java.lang.Throwable
STACKTRACE:

......I then tried the Connecion Pool manually with DBCP to check it is a problm with tomcat or ont. Still the exception comes after a few transactions. I re-checked the code and I am closing all connections in finally block. I searched in net for a solution, but couldnt find any. Is that a problm with mysql? has anyone experienced it? Any help will be greatly appreciated
thanks

Odd that Throwable is the exception logged. What does your finally block actually look like? As an experiment, what happens if you execute the following line of hypothetical code in your 'finally' block?
finally {
System.out.println(conn.getClass().getName());

Intermittent java.sql.SQLException: Closed Connection HELP

We are using 10G rac, with jdbc string with failover with ojdbc14.jar thin client. I am getting this intermittent error
I can't understand why, my dba says there are no alrets on dbs. Never had an issue with code base on 9i, and classes12.jar. Using jdk 1.42. Usually when bounce weblogic we are okay, running 8.1sp2. I can't really bounce weblogic when this happens everytime so I need to figure out root cause and a way to fix the pool without bouncing. I tried reseting the pool won't work, funnny thing is other pools connnecting to same db, but different schema are not showing this error. any help would be appreiciated.
Anyone come across this issue Help

Your pool could be faster, without any
bad side-effects, by turning off TestConnectionsOnCreate
and TestConnectionsOnRelease. They don't help. I would
also suggest turning off shrinking. Those changes will
make the pool faster and more stable. I''d like the
stack trace to see if there's any hint about who closed
the connection...

SQLException - Closed Connection

Hi all,
We are getting the following exception in our client code. We need to fix this error. I want to know why actually such exception occurs and what might be the possible solution(s)? Any help will be appreciated.

Ok, can you once do right click on WEB folder under your project folder and click publish once or twice.
And then restart SQL server and also clear console and try.
I hope Connection closed means there is no connection establishing betweem MII and Server defined.
Is this happening only in Dev or in also Quality server?

"Closed Connection" occurs too much After deployment on WebSphere

"oracle.adf.controller.faces.lifecycle.Utils buildFacesMessage ADF: Adding the following JSF error message: Closed Connection
java.sql.SQLRecoverableException: Closed Connection"
"Closed Connection" message appears to the user too much after deploying on Websphere. How to disable this message.

FYI, I followed the steps listed in Administrator's Guide for Oracle Application Development Framework
at http://docs.oracle.com/cd/E35521_01/admin.111230/e16179/monitor.htm#CHDEGIAH
and that resolved my Closed Connection issue.
3.8.1 How to Configure WebSphere to Allow Reuse of Query Result Sets
WebSphere Application Server closes shared database connections between application generated requests. You need to set two properties in WebSphere to allow reuse of result sets.
Use the WebSphere Application Server administrative console to set the non-transactional datasource and DisableMultiThreadedServletConnectionMgmt properties.
To set properties in WebSphere to reuse results sets:
Start WebSphere Application Server administrative console.
Navigate to Data sources > DB2 Universal JDBC Driver XA DataSource > WebSphere Application Server data source properties and set Non-transactional data source to enabled.
Save the configuration.
Navigate to Application servers > server_name > Web Container > Custom Properties and set DisableMultiThreadedServletConnectionMgmt to true.
Save the configuration.
Restart WebSphere Application Server.
Setting these two properties will enable your deployed application to reuse result sets across requests.

Completely Random SQLException: Closed Connection: next

I don't have the code in front of me right now, but I can give you a break down.
Class DbConnection{
Protected Connection dbcon;
public void setDbConnection(DbConnection db){
public void getDbConnection(){
return dbcon;
public void close(){
dbcon.close()
Class Servlet Extends HttpServlet Implements SingleThreadModel{
protected DbConnection dbcon;
public void startConnection(DbConnection){
dbcon.setDbConnection(DbConnection.getDbConnection());
Class SubServlet extends Servlet{
public void doGet(){
startConnection(dbCon);
try{
do some sort of query or execute a stored procedure
}finally{
dbCon.close()
This is kinda the jist of what the servlet is going. All connections are closed in a Try Finally block and the connections are opened right before the try finally block. The problem is that it works for the most part. But once in a while, there would be a closed connection problem whether executing a query or a stored procedure. It would read several rows from the resultset before the closed connection. Or while it's about to execute a stored procedure, it will have that db connection, up until it is about to execute the sp. Since I've implemented the singlethreadmodel, is it really still threadsafe? The connection is to a huge db, but I've written a program to connect, query (large query), disconnect a thousand times to just test the connections. So far, seems like it's my code. Please, any help would be great, throw out ideas and I'll test them. So far I've exhausted every idea I've had so far.

Hi,
Did you ever solve this problem ?
Please share what you did ?
Thanks.

Web Service exception: Closed Connection

I build a J2EE 1.3 Web Service using JDeveloper 10.1.3 by generating it from a PL/SQL procedure. It works fine on the embedded server and even on the standalone OC4J. When I deploy it on an OAS 10.1.3 it works fine initially but the day after I start to receive the following SOAP message:
<?xml version="1.0" encoding="UTF-8" ?>
- <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

</SOAP-ENV:Fault>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

When I program a non-web application I use the following code to connect to and query a SQL Server database (I have omitted the try -catch sections):
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
String url = "jdbc:sqlserver://localhost:2766;databaseName=Cosmotim;IntegratedSecurity=true";
Connection conn = DriverManager.getConnection(url);
Statement s1=conn.createStatement();
String select="SELECT * FROM [Table name]";
ResultSet DBSet=s1.executeQuery(select1);But when I use the same code in a Web Service method with return type String and I try to deploy the Web service (to Java System Application Server PE 9 with NetBeans) I get many error messages and I can't deploy the service.
I cannot understand why I can't deploy this WS but I can deploy other Web Services which do not use database connectivity.

J2ee Admin User locked on SDM Deployment - BI 7.0 and EP 7.0

Hi,
We had a recent issue on BI iview publishing from the BEX WAD 7.0 in our Production Portal server.
The BEX WAD had the error " Java communication error"
" An Error occured during communication with the BI Components of the J2ee engine"
We traced down to identify that the current stack NW 7.0 SP14 BI Components had issues and had to patch to the next level
However, during deployment of the patch using SDM, the components (all) failed posting the following error. The SDM deployment got struck and the J2ee Engine user j2ee_admin was locked.
Only a restart of the j2ee engine is allowing us to get the Visual Admin connected. But the SDM deployment again is failing and admin user gets locked. Is there any tested solution to solve this.
Kindly help asap.

Hi Anup,
The restart unlocks the j2ee engine admin user and i am able to login to Visual admin and SDM and not otherwise (SDM is hanged and doesnot allow another session and hence only restart helps me to get into SDM again)
Admin Pwds reset etc from config tool secure store and all possible solutions have been tried before restart.
However, after restart, when we try to deploy again, the deploy fails saying the same msg
Caught exception while checking the login credentials for SAP J2EE Engine. Check whether the SAP J2EE Engine is up and running.com.sap.engine.deploy.manager.DeployManagerException: ERROR: Cannot connect to Host: [xxx] with user name: [j2ee_admin]check your login information.
com.sap.engine.services.jndi.persistent.exceptions.NamingException: Exception during getInitialContext operation. No server is running. [Root exception is com.sap.engine.services.security.exceptions.BaseLoginException: Exception in creating new RemoteLoginContext instance.]
Any clues ?
Regards
Venkat.
