Reading ampersand from directory path

I've searched these forums and google to no avail on this problem.
I'm trying to read in directory paths through a JSP and here is my code to do this:
String dirName;
dirName = request.getParameter("dirName");
if ( dirName == null ) dirName = "";
System.out.println("dirName = " + dirName);
The problem I'm having is if a (Windows) directory name contains an ampersand (i.e. AT&T) - the output is: 'dirName = AT' and so the string cuts off at the ampersand. Is there any way to recognize this character?

Thanks for the quick response.
I sub'd in the following now:
dirName = request.getParameter(URLEncoder.encode("dirName"));
However, the ampersand still is not being encoded as %26 (even though spaces in directory names are encoded as %20). What my JSP does is make directory names links which allow a user to click through them to view the contents. Here's the code I'm using to do this which is within a loop and the i gets incremented (this all works - except for the case where the directory name has an &):
<a href="search.jsp?dirName=<%= path[ i %">"><%= path[ i ] %></a><br>
Any ideas? TIA

"Failed to load main class manifest attribute from " directory path

i get this error when trying to run a jar file i made with eclipse. does anyone know how to fix it? thanks derek
"Failed to load main class manifest attribute from "<directory path>

A JAR file is simply a collection of class files, in order to make it an "executable" JAR file you must specify which class file is the "main" class file. In other words, which class should the runtime start executing first. You do this using what is called a manifest file, this is meta information included into the JAR file that the runtime extracts and uses. One attribute is the Main-Class key, which specifies the application's entry point.
The Java tutorial goes into further detail on how to do this
http://java.sun.com/docs/books/tutorial/deployment/jar/appman.html
You may also do this using Eclipse by going File -> Export -> Java -> JAR and follow the wizard.
Using Netbeans this almost comes for free.

Read file from directory, update contents of the each file

hai,
I could not understand how to debug the error i have now.
target
1- read the files from directory // i able ot do this part
2- for each file
for each file read the content & compare with the existing List & update the list // i able to do this part
when i try to combine both parts , i got some following error
run:
E:\java\check\100130.ixf
Error: children[i] (The system cannot find the file specified)

Hello,
Yes, you can use XmlDocument, XmlNodeList, XmlElement, XmlNode etc to read infopath file via code. Just add "using System.Xml" as reference in your solution.
Refer below link with sample code:

Urgent: read pdfs from network path?

Hi friends,
I have a probem:
When I try to read a pdf (which is in a local network path) my applicattion does it ok only if I've logged on windows as administrator user in my PC, but it doesn't work if I try to log with another user... Any idea?
Can I solve this question modifying my forms application? (How??) or it's only a windows permissions problem?
Thanks
Jose

I can think of two ways to set the permissions. One is with HOST and then a command-line tool to set the permissions. I think there was something like that in the NT/Windows Resource Kits. The other one would be to use ORA_FFI and call a DLL that can set the permissions for you.
But in either ways, you're doing these modifications using the currently logged on user. If the problem is that this user doesn't have access to the file, he/she cannot set the security settings either. You would have to set the access permissions on creation of the file.
But you not just set the default permission of the directory in such a way that any newly created file gets the correct permissions?
One last resort would be to schedule a script through the "at" command at scheduled intervals under a 'superuser" that will set the correct permissions.

How to play a video from directory path

I'm not able to play a video while clickng the play button. It was appering a black screen while chilckng the button. y this was happening please help me im new to ios..

Hi,
To retrieve the data from database, I suggest that you could use DAO and you could iterate the records.
There is a link about RecordSet of DAO that can help you:
# Database.OpenRecordset Method (DAO)
https://msdn.microsoft.com/en-us/library/office/ff820966.aspx?f=255&MSPPError=-2147217396
For this requirement of play video, I suggest that you could create a new form, then add the Windows Media Player ActiveX control to the form.
You could set the value to URL property to specify the media file. To full screen the player, you could set
fullScreen to True.
For the issue of play one after another or play a video through VBA, they are more related to VBA, the VBA forum is the better place for VBA questions, I suggest that you could post it there for solutions.

Does not read from the path in default.env

Hi All,
I have given the path of my forms directories in default.env for my 10gDS Suite. While running it does not read it from the path that I have provided in that file. I also specified the same path in registry still the same error. The error message reads like FRM-18108: Failed to load the following objects.
Any help will be appreciated.
Thanks.

Ok, I'm stumped!
I thought I would see what would cause the Forms Builder to fail opening an fmb, so I changed my FORMS_PATH value in the default.env file by removing the second directory listed there. Opening a form in the builder gave me two errors:
FRM-18108: Failed to load the following objects. (Listed the objects in our Ref form.)
FRM-10102: Cannot attach PL/SQL library...
Then I changed the FORMS_PATH back, but now, I am unable to open a form without those errors in the Forms Builder.
My forms_path line looks like this:
FORMS_PATH=C:\oracle\DevSuiteHome_1\forms;C:\Users\Steve\01\fmb10The only thing I can do now to get a form to open without the errors is to copy the reference fmb and the PLL library from C:\Users\Steve\01\fmb10 to C:\oracle\DevSuiteHome_1\forms
It feels like I am going crazy, because this all worked before, and now I cannot get it to work.
By the way, I am using Windows Vista and Forms 10.1.2.3.0

File Adapter Directory Path

Hi,
I have hot coded the directory path.
I want to read the input directory path for fileadapter from a file(i will have a configuration file where i will set values for parameters).
Regards
Vishnu

Thanks Ashish, it is helpful.
Just one more question, I am not sure what value do I add from making physical to logical. Let's say if I have file polling read operation (not sync read), then if I configure physical path it will be hardcoded in jca wsdl file, if I configure logical it is hard coded in bpel.xml file.
Unlike other preferences I am not able to update my logical directory in bpel.xml at run time in descripter tab. So if my input directory changes for some reason, I have to replace it (via ANT) and redeploy the process no matter what.
Let me know if I understand it correctly.
Vishnu,
Please clarify which operation you are using, if you are using sync read or write, you can read your directory and file name from parameter file and pass it to adapter for reading that file. Adapter will give you content and also the name file/directory as header variable.
If you are using polling operation, "after reading" the file adapter will provide file name and directory in header. But if you want pass the name of directory to adapter for reading the file, then I have asked similar question to Ashish.

Chintan

PI sender communication channel not reading files from NFS directory

Hello,
I have a sender communication channel configured to read file from NFS directory which is on ECC server. A program in ECC generates the file and puts it on the ECC server in the output directory. PI sender communication channel is supposed to pickup this file and process it. If I give the NFS path as the source directory, I am getting error: Configured source directory '//Server/DIR/OUT' does not exist. I tried putting '
Server\DIR\OUT' too but same error. Do I have to add the NFS path of ECC into PI as logical path?
Any suggestions?
Thanks,
Sangita

Hello Sangita,
Your ECC server is an external system, therefore you need to activate FTP service in that system and use the transport protocol FTP:
http://help.sap.com/saphelp_nw04/helpdata/en/e3/94007075cae04f930cc4c034e411e1/content.htm
You can use NFS protocol when you have a local directory in XI server.

Above is the output when select * from dca additional data.
I have edited the r_bmw to varchar (32757 BYTE);
however, the same errors still appear. Would I need to change the select statement to a different table...and not dca additional data?
ThanksSo you have created a directory name r_bmw
create directory r_bmw as 'C:\BMW';
grant read, write on directory r_bmw to bmw;And your are querying select * from dca additional data, which doesn't return your recently created directory.... So... what to do what to do.... You should query the all_directories with directory_name = 'r_bmw'.

I wanna read text files from directory that contain - lots of other directorys... and by using this code I have error,,,
Can anyone help me plzzz
Edited by: Shamma on Oct 9, 2008 3:32 AM

You actually have more than 1 problem: you cannot traverse directories recursively and you get a NullPointerException.
For the first problem you might want to verify what this statement returns:
child.toString() (I honestly don't understand why you are calling toString() on a String object, but that's not the real problem!)
You probably expect it to be a full absolute path.
The NullPointerException has already been pointed out by masijade.

How to make SSIS packages automatically read the input file from a path?

Currently I am using a SSIS package to read data from a .dat file and load it into SQL Server tables.
I am placing the input .dat file on the desktop. In the connection manager -> Browse option, I am pointing this file to create connection.
The file naming convention is like - aSNAP_Data_20140926_P-2014-09-26_07.02.36
However, I need the SSIS package to automatically read the input file from a folder which is located in a remote server. This folder has lots of files where input files are added on a daily basis with the date value in the file name as mentioned above.
I want to schedule the SSIS package to run daily and take the latest file in the folder based on the date.
Please let me know how to do it. Any help would be highly appreciated.....
Thanks in advance.

Hi SQL_SSIS_Dev,
According to your description, you want to get the latest file from a path to a SQL Server table. After testing the issue in my environment, we can refer to the following steps to achieve your requirement:
Create two variables, VarFolderPath stores the folder path in which our files exist, VarFileName hold the value of most recent File Name.
Drag a Script Task from SSIS Toolbox to Control Flow Pane, then select “User::VarFolderPath” as ReadOnlyVariables, select “User::VarFileName” as ReadWriteVariables.
Then Edit Script with the C# code below:
Add “using System.IO;” into namespace.
Add the code below under Main function:
var directory= new DirectoryInfo(Dts.Variables["User::VarFolderPath"].Value.ToString());
            FileInfo[] files = directory.GetFiles();
            DateTime lastModified = DateTime.MinValue;
            foreach (FileInfo file in files)
                if (file.LastWriteTime > lastModified)
                    lastModified = file.LastWriteTime;
                    Dts.Variables["User::VarFileName"].Value = file.ToString();
Drag a Data Flow Task to Control Flow Pane and connect to Script Task.
In the Data Flow Task, drag a Flat File Source with a file in the source folder as all the files have same structure as the File name.
Add the property below the Flat File Connection Manger expression:
Property: ConnectionString      Expression: @[User::VarFolderPath] +"\\"+ @[User::VarFileName]
Drag an OLE DB Destination that connect to the Flat File Source, then configure a table to store the data.
The following screenshot is for your reference:
If there are any other questions, please feel free to ask.
Thanks,
