I have a dtspackage which is executed through the C# coding.Earlier we have used sql server 2008 r2, Now we have moved to sql server 2012. The package was working fine with sql server 2008 while executing through C#code.But now while loading the Config file it throwing the exception like **
Microsoft.SqlServer.Dts.Runtime.DtsTaskException was caught
Message=Type mismatch. (Exception from HRESULT: 0x80020005

The DTS package will download the xml content and transform to table.And it download one excel file and fetch the data from the excel.
The package running successful when i execute through the Execute Package Utility
Please guide me to fix the issue.
Thanks In Advance

I'm using EPPLUS to generate Excel file from Database table but the file created stay on Read-only mode until the full SSIS process is stopped.
I need to move the file after later in the process and this will always fail with the following message in SSIS:
[File System Task] Error: An error occurred with the following error
message: "The process cannot access the file because it is being used
by another process.".
When I try to open the file in excel I got the "File in Use"
book1.xlsx is locked for editing
by 'another user'.
Open 'Read-Only' or click 'Notify' to open read-only and receive notification when the document is no longer in use.
I hope you'll be able to help me.
Here is my code:
public void Main()
{
try
{
String FilePath = Dts.Variables["$Package::DestinationFileName"].Value.ToString();
String TableName = Dts.Variables["$Package::SourceTableName"].Value.ToString();
String ConnStr = Dts.Variables["$Project::ConnStr_DataWarehouse"].Value.ToString();
//SqlConnection Conn = (SqlConnection)(Dts.Connections["DW"].AcquireConnection(Dts.Transaction) as SqlConnection);
using (SqlConnection Conn = new SqlConnection(ConnStr))
{
String Sql = "SELECT * FROM " + TableName;
if (File.Exists(FilePath))
{
try { File.Delete(FilePath); }
catch (Exception ex) { MessageBox.Show(ex.Message.ToString()); Dts.TaskResult = (int)ScriptResults.Failure; }
}
using (DataTable dt = new DataTable())
{
using (SqlCommand cmd = new SqlCommand(Sql, Conn))
{
Conn.Open();
using (SqlDataAdapter da = new SqlDataAdapter(cmd))
{
da.Fill(dt);
FileInfo newFile = new FileInfo(FilePath);
using (ExcelPackage p = new ExcelPackage(newFile))
{
using (ExcelWorksheet ws = p.Workbook.Worksheets.Add("RejectetionReport"))
{
ws.Cells["A1"].LoadFromDataTable(dt, true);
p.Save();
}
}
}
Conn.Close();
}

I'm using EPPLUS 4.0.5 which I plan to update to 4.1 but the release note doesn't seam to cover this issue.
EDIT:
I've upgraded to 4.1 but the issue still exists.
I found the issue.
There is a bug in the EPPLUS library which is not disposing of a stream before disposal of the package.
I've submitted a fix an pull request under fork DebugPackageDispose
Hopefully, this will be integrated soon.
In a java service, without a function declaration, a function call is there and only compile time error comes. But the output is as expected with no run time errors. How is that possible? Can anyone please explain?
"The method functionName() is undefined" is the error it shows.
Below is the code.
public static final void documentToStringVals(IData pipeline)
throws ServiceException {
// pipeline
IDataCursor pipelineCursor = pipeline.getCursor();
String success = "false";
IData inputDoc = null;
String outputValue = "";
String headerYN = "N";
boolean headerValue = false;
String delimiter = ",";
String newline = System.getProperty("line.separator");
if (pipelineCursor.first("inputDocument") ) {
inputDoc = (IData) pipelineCursor.getValue();
}
else {
throw new ServiceException("inputDocument is a required parameter");
}
if (pipelineCursor.first("delimiter") ) {
delimiter = (String) pipelineCursor.getValue();
}
if (pipelineCursor.first("headerYN") ) {
headerYN = (String) pipelineCursor.getValue();
}
if (headerYN.equalsIgnoreCase("Y")) {
headerValue = true;
}
try {
outputValue = docValuesToString(inputDoc, headerValue, delimiter);
outputValue += newline;
success = "true";
}
catch (Exception e) {
System.out.println("Exception in getting string from document: " + e.getMessage());
pipelineCursor.insertAfter("errorMessage", e.getMessage());
}
pipelineCursor.insertAfter("success", success);
pipelineCursor.insertAfter("outputValue", outputValue);
pipelineCursor.destroy();
}
The code you posted has no reference to "functionName", so I suspect there's a reference to it either in the shared code section or in another Java service in the same folder. Given that all Java services in a folder get compiled into a single class, and therefore all those services need to be compiled together, this could cause the error message when you're compiling the service above.
I'm trying to connect from a Google Endpoints server to a Google Cloud SQL server. I'm modifying the Greetings.getGreeting() method in this tutorial:
https://cloud.google.com/appengine/docs/java/endpoints/getstarted/backend/helloendpoints
to call the Cloud mysql database as demonstrated in this tutorial (see doGet method):
https://cloud.google.com/appengine/docs/java/cloud-sql/#enable_connector_j
I have made sure that I can connect to the database from my machine mysql client. The database instance "simple" has a single table "simpletable" who's rows hold an entityID and a string. (But I'm not able to connect, so that's not too important yet.)
This is my endpoints code:

Whichever way I build+depl0y it (Dev or cloud), I always get

or

I've already looked at these:

What does 'Class.forName("org.sqlite.JDBC");' do?
I'm building with Maven and working on IntelliJ IDE.
Any help is greatly appreciated. Thanks.
I am trying to establish a jdbc connection with SQL Server 2008 R2, using the SQLJDBC4 jar file and JDK 1.6. I am using Netbeans IDE and have added the SQLJDBC4 jar and added the path to the database in the 'databases' section in the services. The code is as below:
package connect2;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
public class Connect2 {
public static void main(String[] args) throws SQLException {
Connection conn;
conn = null;
System.out.println("Done....");
try
{
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
conn = DriverManager.getConnection ("jdbc:sqlserver://172.17.39.13\\CRM:1433;databaseName=crm_xchanging","crm_xchanging","Welcome001");
System.out.println ("Database connection established");
}
catch (ClassNotFoundException e)
{
System.out.println (e);
}
catch (SQLException ex)
{
System.out.println(" error");
}
finally
{
if (conn != null)
{
try{
Statement st = conn.createStatement();
ResultSet res = st.executeQuery("SELECT * FROM usertable");
System.out.println("User Name: " );
while (res.next()) {
String employeeName = res.getString("user_name");
System.out.println(employeeName);
}
conn.close();
}
catch(SQLException ex){
System.err.println("SQLException information");
while(ex!=null) {
System.err.println ("Error msg: " + ex.getMessage());
System.err.println ("SQLSTATE: " + ex.getSQLState());
System.err.println ("Error code: " + ex.getErrorCode());
ex = ex.getNextException();
// For drivers that support chained exceptions
}}
}
}
}
}
This is the output I'm getting:
run:
Done....
Database connection established
SQLException information
Error msg: Connection reset
SQLSTATE: 08S01
Error code: 0
BUILD SUCCESSFUL (total time: 1 second)
I don't think there is any mistake in the code or the JDK. I have also tried to set the max no. of active connections for SQL Server as 0 (infinite). How do I solve this problem?
There is a known bug introduced in Java 6u29 that causes SSL failure specifically with SQL Server 2008 R2. An Atlassian Fisheye troubleshooting page suggests a fix was incomplete.
Oracle delivered a fix in 6u30, although for at least one affected
client not even Java 1.7 worked.
On my development team we have found this bug to impact Java 8 at as well. One of the recommendation in the Fisheye article is to disable CBC protection using a JVM flag and that has also worked for me for SSL Java 8 SSL with a SQL Server 2008 R2 connection.
-Djsse.enableCBCProtection=false
The other suggestion is to revert to Java 1.6.0_24.
Iam calling a web service through my web service dynamically. I stored serviceName, MethodToCall, and array of parameters in my database table and execute these two methods to call a dynamic service url with .asmx extention and its method without adding its reference in my app. It works fine.

Now the problem arraize when i have two different client servers. and calling a service from one server to the service deployed on other server. Follwing two kind of error log occurs. Cant find the exact reson for cope up this problem.

Please Carry Out Following Steps :
1) First of all try to access your service by adding reference of it.
It it works fine then we can say that there is no problem related to accessibility and permission.
2) If its not work then there is a problem with connection.
-->So Check Configuration in your service and try to set timeout for your web service.
(http://social.msdn.microsoft.com/Forums/vstudio/en-US/ed89ae3c-e5f8-401b-bcc7-
333579a9f0fe/webservice-client-timeout)
3)Now try after setting the timeout.
it operation completes successfully after above change that means now you can check with your web client method(dymamic calling).
4) If still problem persists then this might be network latency issue. Check the n/w latency between your client and server.
it will helps you.
