How to use Java with PL/SQL commands to send an email with attachment

Apologizes in advance if this is the wrong place to ask the question.
I need to use Java with PL/SQL commands to send an email with attachment. My java application runs from the command line and does some magic to gather info from an Oracle 11g db. If the DB has sendmail configured, I'd like to send the results of the data gathering as an attachment to the email addresses. I'm not sure how to do this. I've been reading up on on PL/SQL can send email with UTL_SMTP - with attachments. I'm just not sure how to translate that into being triggered by my Java application. Any suggestions or pointers on what I should read would be appreciated.
Background - I've been programming in Java for 10+ years, but this is my first time using databases. I also have been on these forums for a long time, but lost my profile when it was switched to Oracle.
Thanks for all help.

The original requirements were put together and given to me, an Oracle newbie. They expected the Java app to use something intrinsic to Oracle and Unix sendmail. To solve my problem, I use a JDBC connection to run some SQL commands. I take that data, format it and send the results by email to the user. By default the requirement is to send it as an HTML attachment using Unix 'sendmail'. So I do that using Runtime exec. I have also added JavaMail functionality as an alternative to sendmail. It works great and as expected.Sounds like a reasonable solution.
Note however that PL/SQL itself can send email. And PL/SQL can call unix sendmail too.
However myself I would have done it in java with JavaMail.

Java and MS SQL Server 2000 problem, please help

please help me. I am using java and MS SQL Server 2000, and I'm trying to access and verify the login. I'm getting the following error message: [Microsoft][ODBC SQL Server Driver]Invalid Descriptor Index

Doesn't the following link give you enough information?

Anyway .. This error means that the given ResultSet column index which you're trying to retrieve the value from is out of the range.

How i connect to SQL server using java?

hi every body
i need to connect to a sql server database using java
i do not know sql driver in java
plz help me

This is certainly the wrong forum for that question. Search in the JDBC forum. This has been asked and answered many times.

How do i connect to sql server using java?

hi ever body

Microsoft make a jdbc driver and it is readily available through MSDN. Here is a link http://msdn2.microsoft.com/en-us/data/aa937724.aspx. Whatever jdbc driver you are looking for, Google it, and if it exists you'll find it in 10 seconds.

Using MapViewer from PL/SQL vs Java

Hi group!
The MapViewer User's Guide has this to say about using MapViewer from PL/SQL:
"The usage model for the SDO_MVCLIENT package is almost identical to that of
MapViewer JavaBean-based API" etc etc .. "For usage and reference information about specific functions or procedures, see the description of the associated JavaBean-Based API. methods and interfaces in Chapter 4"
If I don't misunderstand the basic concept, in a Java Web App (using the MapViewer Bean) you create a MapViewer object for each HTTP-user-session, like so:
MapViewer mv = new MapViewer("http://my_corp.com:8888/mapviewer/omserver");
... which you would then store in the user's session object, so that the MapViewer Bean conveniently holds the map's state on the user's behalf.
To do the equivalent in PL/SQL, the User's Guide suggests:
"connect scott/tiger
call sdo_mvclient.createmapviewerclient(
'http://www.mycorp.com:8888/mapviewer/omserver') ;
The preceding example creates, in the current session, a unique MapViewer client
handle to the MapViewer service URL"
Does "current session" refer to the HTTP-user-session? While I've used PL/SQL before, I've not used the PL/SQL Web Toolkit. Is the session handling implicit here (and invisible?) or should the sdo_mvclient be subsequently stored in the PL/SQL equivalent of a (J2EE) HttpSession object?
YT

Part of the answer will depend on how you plan to deploy the application. If you have a few, local clients you could go with the traditional client/server model. If you have a lot of clients and/or they are spread out over a relatively large area (like a campus setting), a web front-end will save you a lot of hassels down the road when it comes time to upgrade.
Regardless of the the front end, I can tell you that I have been greatly impressed with the throughput you can get by moving most of the code to PL/SQL packages. A few years ago we reworked a VB/Oracle app by moving a lot of the code out of VB and into packages, leaving the client to essentially call procedures and format the output. We had more than a 3x performance increase on the same hardware and our network utilization decreased noticably.
I am now in the process of replacing the client code with Java servlets/JSP, primarily because of the maintenance hassles I mentioned earlier. There are some limitations with an HTML page but most of these have been cosmetic so far.
We are still relying heavily on PL/SQL packages. The servlet code basically gets a request, calls a package to get the data, then hands the results to a JSP page. The JSP then formats the output and sends it to the client. We are little more than halfway through the re-write, but it appears performance will increase again. Not as noticably as before, but I will take what I can get. As you have seen, once something is rolled out it always ends up getting used more than you anticipated. Better to over-engineer now than have to patch it once it is live.

How do you compare 2 dates in SQL Server 2000 DB using Java?
Let's say we have two fields: Date Reported and Target Finish Date.
Date Reported is 09-10-2004 09:55:55: PM
Target Finish Date is 09-12-2004 11:59:59: PM
What i want to happen is i want to convert both dates to days and get the difference of the two.
can SQL Server 2000 DB do this?

it doesnt wrk.
ok here's what i did:
iv tested a simple code for this case.
I created a table name tblDate which has 3 columns namely date_ID, date_From (datatype datetime), date_To (datatype datetime).
I inserted 1 row: date_ID has the value 1, date_From has the value 10/22/2004, and date_To has the value 10/24/2004.
i run the java code below:
int days = 0;
          String query = "SELECT date_From, date_To cast(date_From-date_To AS int) AS Diff FROM tblZoo WHERE date_ID = '1'";
          try
               DBConnect db = new DBConnect();
               db.openCon();
               ResultSet rs = db.execute(query);
               while(rs.next())
                    days = rs.getInt("Diff");
               db.closeCon();
          catch (Exception ex)
               System.out.println("Error on Execution: " + ex);
          return days;___________

How to run SQL script file on Linux using Java ?

        String sqlPromptLines="";
        String currentFunctionName = "";

            String password = jPasswordField1.getText();
            String databaseName = jTextField3.getText();

                                    return false;
                int count = 0;
                    for (int i = 0; i<list_files.length;i++){
                        script_location = "@" + list_files.getAbsolutePath();//ORACLE
//currentFunctionName = list_files[i].getName();
StringTokenizer st = new StringTokenizer(list_files[i].getName(), ".");
while(st.hasMoreTokens()) {

String currentLine = null;
while ((currentLine = in.readLine()) != null) {

count ++;
System.out.println(count+" " + currentLine);
if(currentLine.equalsIgnoreCase("Function created.")){

}// end id Connection is not null
Above code working appropriate on Windows but not on Linux.
is there any changes needed ?

Hi gimbal2,
about code
jTextArea1.setText(e1.getMessage());I am using this code so that the user will be prompted with a message rather than stack trace.
About the issue I am getting on linux i believe its because of following statement.
processBuilder = new ProcessBuilder("sqlplus",userName+"/"+password+"@"+databaseName, script_location); //ORACLERegards,

Create table dinamically using java sql types?

Hi! I've an application that reads an XML file. This file contains de definitions of some tables, using java sql types. For example:
<dbtable>
<dbtablename>Name of table</dbtablename>
<dbtablefield>
    <name>Name of table field</name>
    <type>java.sql.Types.VARCHAR</type>
    <length>10</lenght>
    <canNull>0</canNull>
    <isPK>1</isPK>
</dbtablefield>
</dbtable>That's a little example of one table, with one field. Is a java.sql.Types.VARCHAR (or is equivalent in int), which has a size of 10, it cannot be null and is a primary key for the table.
Now, the lenght, null, and primary keys are not problem at all. What I want to know, is how do I create de table using the java.sql.Types. I mean, I don't want to hard code:
String s = "CREATE TABLE name (COLUMN VARCHAR(10)...";Instead, I want to use some "wild cards", as are used in PreparedStatement. The idea of this is that no matter what DB I'm using, I must always be capable of creating the tables not worrying for the DB. I mean, I must be able to create the table in Oracle, SQL Server, DB2, etc., using the same XML and the same java class.
Something like:
String s = "CREATE TABLE name (COLUMN ? (10)...";
someobject.setObject(1,java.sql.Types.VARCHAR);
someobject.execute(); //create tableIs this possible? Or do I have to make a map for each DB?
Thanks a lot for your help! Dukes available!

you can provide some fields at runtime..
for example
"CREATE TABLE name (COLUMN" + arg[1] +"(10)..."
here arg is the string array passed into the main.

How to access PL/SQL Web Services using java

New to Webservices. Created PL/SQL Web Service using JDeveloper. Vendor is not sure how to access it using java. Can anyone please help to point in the right direction or provide some sample ?

So if I'm correct you have already exposed a PL/SQL procedure or function as web service?
In that case you can generate a proxy (client) for the generated web service using JDeveloper. It will generate Java code which invokes the web service.
See the wizard in JDeveloper, it should be in the same category as the create PL/SQL web service wizard.
