Sending mail in a Java Stored Procedure

Question: What is the best way to have a Java Stored Procedure connect to our mailhost and send an email? I have been trying to use URL and URLConnection, but I found out URL somehow does not support the "mailto" protocol in the Java Stored Procedure. Funny enough the "mailto" protocol is definetely supported by URL when I test it in the JDK virtual machine.
Maybe this is the reason: I read in the 8i docs that the 8i Virtual Machine is only JDK1.1.6 compliant.
Unfortunately I can't find the 1.1.6 docs anywhere. So I cannot do any research on what protocals are supported in JDK1.1.6 .
Conclusion: Is it possible to send an email in a Java Stored Procedure, and how?
Thanks in advance :-) Johan

The Java mail API was a set of extension libraries for the 1.1 JDK. I have heard of folks who succeeded in loading these intot he database and then using them from within a Java stored procedure.

NameFromLastDDL Error during java stored procedure upload...

Hi guys,
I am trying to upload a class to send email within a java stored procedure.
JDeveloper fails to upload the class, and the error message doesn't help me:
I guess the automatically generated SQL statment features a "NameFromLastDDL" argument, but i have no control over that....anybody had this issue before ?
Following, the "ugly" exception:

Hello,
Thanks for the reply. Actually I have seen that post before creating this thread. I thought that I could make use of java mail to work around this problem. I created a java class that succesfully sends mail to SSL host. I tried to call this java class from pl-sql through java stored procedure. That did not work
So, is this not supported in Oracle ? Please note that I have tested this in both 9i and 11g , in both the versions I got the error. You can refer to the code in the above post.
Thanks

Procedure or Java Stored procedure to send message/xml/data to MQ Series Qu

Hi
Using a simple Oracle Procedure or Oracle's Java stored procedure, I would like to send data to MQ Queue. It would be great if someone can help me with a piece of sample code.
Thanks in Advance

Hi Prabhu, Vlad
This is the same question which i asked few days back.
Our Backend system, only understands ISO8583 message format. And since I work in a financial environment, I can only send and receive data using "socket" protocol (tcp/ip).
So, This is where I have stuck forever...
I create a BS. select "any xml" . Then, I select "socket" as protocol. and click on finish.
Then, I create a Proxy Service based on my BS.
But, where/how do I convert the input xml packet into an ISO8583 format and send it over to my backend system ???

Weblogic 6.1 & Oracle Java Stored Procedures

Hi all
I need to access a EJB deployed into Weblogic 6.1 (It's a mail sender EJB) when an event occurs in a Oracle 8.1.7 DataBase (when a table were updated).
I think the only way to do it is firing a trigger, this trigger uses a Java Stored Procedure that connects with the EJB via JNDI.
And here comes the problem:
must I load the weblogic.jar (25M) into the DataBase through loadjava??
There is no a way to include jars in the Oracle classpath??
Please help
Thanks in advance.
David.

Hi,
I want to ask you one thing:
Once the procedure is called is it not executing at the database?The Oracle process handling it(Procedure).So wont that be able to call the trigger as it works in the (Oracle)environment.
So where does the importing of the java classes(Object) is related to
the Trigger invocation....

Issue with XSL transformation in Java Stored Procedure

Hi,
Am having issue applying XSL transformation in Java Stored procedure. I have loaded the java class as well as .XSL files through loadjava uility and their status in DB is VALID.
Below is the code in the java stored procedure:
public static String tranform(String strInputXML ){
URL url = ClassLoader.getSystemClassLoader().getResource(first.xsl);
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
DocumentBuilder builder = factory.newDocumentBuilder();
Document document = builder.parse(new ByteArrayInputStream (strInputXML.getBytes("UTF-8")));
TransformerFactory tFactory = TransformerFactory.newInstance();
StreamSource stylesource = new StreamSource(url.openStream());
Transformer transformer = tFactory.newTransformer(stylesource);
When I run this procedure, am getting following errors:
{color:#ff0000}*ERROR: 'No such file or directory'*
FATAL ERROR: 'Could not compile stylesheet'{color}
My first.xsl file has reference to other excel file (Ex: <xsl:include href="second.xsl"/>) which seems to be causing this error. When I remove the reference, procedure is working fine.
Pls let me know how to resolve this and read the .XSL file with references.
Thanks,

Iam passing an array of objects from Java to the C
file. The total size of data that Iam sending is
around 1GB. I have to load this data into the Shared
memory after getting it in my C file. Iam working on
HP-UX (64-bit). Everything works fine for around 400MB
of data. When I try to send around 500MB of data, the
disk utilization becomes 100%, so does my memory
utilization and I get a "Not enough space" when I try
to access shared memory. I have allocated nearly 2.5GB
in my SHMMAX variable. Also, I have around 45GB of
disk free. The JVM heap size is also at 2048MB. Where did you get the 400/500 number from? Is that the size of the file?
What do you do with the data? Are you doing nothing but copying it byte for byte into shared memory?
If yes then a simple test is to write a C application that does the same thing. If it has problems then it means you have an environment problem.
If no then you are probably increasing the size of the data by creating a structure to hold it. How much overhead does that add to the size of the data?

DBMS_JOB on Java Stored Procedure problem

Hi all,
(running on Oracle 9i : 9.2.0.7.0 64bit on HP/UX)
I have a Java Stored procedure that reads a table
One of the fields in this table is a CLOB containing some more SQL.
We then executeQuery() that SQL (and e-mail the output).
(Obviously I also have PL/SQL wrapper around it, which we'll call PROCNAME).
For certain pieces of SQL, this second executeQuery() fails throwing ORA-00942, but only when run from a DBMS_JOB(!).
Calling "CALL PROCNAME('argument')" from sqlplus/toad works fine, but setting "PROCNAME('argument')" to run as a DBMS Job fails on some SQL with the above error. (All as the same username).
java.lang.StackTraceElement doesn't seem to exist in Oracle java, so the only error I have to go on is e.getMessage() from SQLExecption which returns:
ORA-00942: table or view does not exist
Any help at this strangeness would be appreciated!

Hi Cris:
May be is a problem of the effective user which is running the procedure.
Which is the auth_id directive at the PLSQL call spec?
Look at this example procedure UploadNews for example:
http://dbprism.cvs.sourceforge.net/dbprism/cms-2.1/db/cmsPlSqlCode.sql?revision=1.21&view=markup
this procedure calls to the cmsNews.doImport which is implemented as Java Stored Procedure.
Also check if your loadjava operation is not using -definer flag.
Best regards, Marcelo.

Passing Tables back from Java Stored Procedures

Thomas Kyte has written (in reference to
trying to pass an array back from a stored
function call):
You can do one of two things (and both require the use of
objects). You cannot use PLSQL table types as JDBC cannot bind to
this type -- we must use OBJECT Types.
[snip]
Another way is to use a result set and "select * from
plsql_function". It could look like this:
ops$tkyte@8i> create or replace type myTableType as table of
varchar2 (64);
2 /
Type created.
ops$tkyte@8i>
ops$tkyte@8i>
ops$tkyte@8i> create or replace
2 function demo_proc2( p_rows_to_make_up in number )
3 return myTableType
4 as
5 l_data myTableType := myTableType();
6 begin
7 for i in 1 .. p_rows_to_make_up
8 loop
9 l_data.extend;
10 l_data(i) := 'Made up row ' | | i;
11 end loop;
12 return l_data;
13 end;
14 /
Function created.
ops$tkyte@8i>
ops$tkyte@8i> select *
2 from the ( select cast( demo_proc2(5) as mytableType )
3 from dual );
COLUMN_VALUE
Made up row 1
Made up row 2
Made up row 3
Made up row 4 [Image]
Made up row 5
So, your JDBC program would just run the query to get the data.
If the function "demo_proc2" cannot be called from SQL for
whatever reason (eg: it calls an impure function in another piece
of code or it itself tries to modify the database via an insert
or whatever), you'll just make a package like:
ops$tkyte@8i> create or replace package my_pkg
2 as
3
4 procedure Make_up_the_data( p_rows_to_make_up in
number ); 5 function Get_The_Data return myTableType;
6 end;
7 /
Package created.
ops$tkyte@8i>
ops$tkyte@8i> create or replace package body my_pkg
2 as
3
4 g_data myTableType;
5
6 procedure Make_up_the_data( p_rows_to_make_up in number )
7 as
8 begin
9 g_data := myTableType();
10 for i in 1 .. p_rows_to_make_up
11 loop
12 g_data.extend;
13 g_data(i) := 'Made up row ' | | i;
14 end loop;
15 end;
16
17
18 function get_the_data return myTableType
19 is
20 begin
21 return g_data;
22 end;
23
24 end;
25 /
Package body created.
ops$tkyte@8i>
ops$tkyte@8i> exec my_pkg.make_up_the_data( 3 );
PL/SQL procedure successfully completed.
ops$tkyte@8i>
ops$tkyte@8i> select *
2 from the ( select cast( my_pkg.get_the_data as mytableType
) 3 from dual );
COLUMN_VALUE
Made up row 1
Made up row 2
Made up row 3
And you'll call the procedure followed by a query to get the
data...
I have tried this, and it works perfectly.
My question, is what does the wrapper look
like if the stored function is written
in java instead of PL/SQL? My experiments
with putting the function in java have been
dismal failures. (I supposed I should also
ask how the java stored procedure might
look also, as I suppose that could be where
I have been having a problem)

Thanks for the response Avi, but I think I need to clarify my question. The articles referenced in your link tended to describe using PL/SQL ref cursors in Java stored procedures and also the desire to pass ref cursors from Java to PL/SQL programs. Unfortunately, what I am looking to do is the opposite.
We currently have several Java stored procedures that are accessed via select statements that have become a performance bottleneck in our system. Originally the business requirements were such that only a small number of rows were ever selected and passed into the Java stored procedures. Well, business requirements have changed and now thousands and potentially tens of thousands of rows can be passed in. We benchmarked Java stored procedures vs. PL/SQL stored procedures being accessed via a select statement and PL/SQL had far better performance and scaleable. So, our thought is by decouple the persistence logic into PL/SQL and keeping the business logic in Java stored procedures we can increase performance without having to do a major rewrite of the existing code. This leads to the current problem.
What we currently do is select into a Java stored procedure which has many database access calls. What we would like to do is select against a PL/SQL stored procedure to aggregate the data and then pass that data via a ref cursor (or whatever structure is acceptable) to a Java stored procedure. This would save us a significant amount of work since the current Java stored procedures would simple need to be changed to not make database calls since the data would be handed to them.
Is there a way to send a ref cursor from PL/SQL as an input parameter to a Java stored procedure? My call would potentially look like this:
SELECT java_stored_proc(pl/sql_stored_proc(col_id))
FROM table_of_5000_rows;
Sorry for the lengthy post.

Java Stored Procedures and Sockets

We need to synchronize data real time b/w Oracle and the legacy HP3000 system.
For sending data from Oracle to HP3000 we are thinking of using Sockets.
We dont know whether a socket connection can be established from the Oracle database level or need to be from the OS level(here Linux)
I heard that Java stored procedures(JSP) can establish socket connection.
Can someone provide me pointers regarding
(a) setting up socket connection from the database
(b) possibility of transferring data via sockets and using jdbc, and how to send data efficiently and if it is wise
Thanks,
Vinoj

I don't have much experience with Lite, but I'm running 9i Personal Edition. Any information about triggers can be found in the "ALL_TRIGGERS" view. You will want to filter out any rows where OWNER = 'SYS' unless you created your triggers as SYS. As for procedures and functions, you can see what you have created in the "ALL_OBJECTS" view where OBJECT_TYPE = 'PROCEDURE' or 'FUNCTION', once again filtering out rows where OWNER = 'SYS'. To see the code of any procedure or function, select substr(text,1,80) from ALL_SOURCE where NAME = 'function name' ORDER BY LINE.
Hope this helps!

Jdbc and java stored procedures

Hi all,
I am new to Oracle Java Stored Procedures but I am interested in knowing to which extent is object passing supported.
Can I send any kind of object to a java stored procedure? And back from the procedure? Anybody knows any good resources online about Java Stored Procedures and JDBC?
I also saw that to pass the string back you need to specify java.lang.string, how would I do in order to pass back a user defined object, do I have to register the class in Oracle before (and if yes, how?)or is the classpath enough?
Many thanks,
A.

Hi again,
perhaps I didn't understand exactly what you meant with "publish", AFAIK you have to expose the java class (i.e. RowCounter) by using
CREATE OR REPLACE FUNCTION row_count (tab_name VARCHAR2) RETURN NUMBER
AS LANGUAGE JAVA
NAME 'RowCounter.rowCount(java.lang.String) return int';
(BTW this works fine)
or else you cannot access the java class you loaded on the server, and that's where my questions arose. What if I am passing an object, let's say myObject, shouldn't I use the STRUCT mapping then or something like that?
Or, could you clarify what do you mean by publishing to SQL, I just need to access the class from jdbc, not from PL/SQL or others, but as I understand to call the class from JDBC I need to call the function or procedure that calls the class and then I could call it from PL/SQL as well...
Thanks,
A.

Error calling Java Stored Procedure

hi I am calling java stored procedure from jdbc. i am getting wierd exceptions:
CallableStatement cstmt = conn.prepareCall("begin SEND_MAIL(?,?,?);end;");
cstmt.setString(1,"[email protected]");
cstmt.setString(2,"Mail from Stored Proc");
cstmt.setString(3,"This is test mail from Oracle8i");
cstmt.execute();
i am getting following Exception:
java.sql.SQLException: ORA-29532: Java call terminated by uncaught Java exception: java.security.AccessControlException: the Permission (java.util.PropertyPermission * read,write) has not been granted by dbms_java.grant_permission to SchemaProtectionDomain(ISTORE_CUST|PolicyTableProxy(ISTORE_CUST))
ORA-06512: at "ISTORE_CUST.SEND_MAIL", line 0
ORA-06512: at line 1
null

I think u dont've previleges to run
the procedure.

Error loading Java Stored Procedure

When I attempt to deploy a java stored procedure using JDeveloper I get the following error: "ORA-29545: badly formed class: User has attempted to load a class (TestingJava.Testerama) into a restricted package. Permission can be granted using dbms_java.grant_permission(<user>, LoadClassInPackage...". I have attempted to grant the proper permissions but get a "java.lang.SecurityException: policy table update" error. The user granting the permissions has the Java_Admin role. What do I do?

Help with use of Java Stored Procedures to invoke Java Code within Applicat

Good afternoon everyone
Our development team is looking for some assistance/validation of a design strategy we are deploying for a client. Let me first layout the environment and then the design issue at hand:
Business User Workstation component: Oracle SQL*Developer 1.5.x
Reporting Tool: Actuate e.Spreadsheet A10
Application Web UI: J2EE application developed with Eclipse
Application Scripting: Application has a scripting component whereby business users can write Oracle PL/SQL to perform many of the functions that are available in the Web UI, but can be batched up or repeated several times.
Application Server WebLogic 9.2.3 (client constraint)
Database Serve: Oracle 11g, Release 11.1.0.7
Lots of other stuff included but irrelevant for this conversation.
Here's the scenario in question:
1.     Through the scripting solution, the application user must use PL/SQL to invoke functionality within the Web UI. All PL/SQL that the application user creates does not contain any SQL. Instead our security model mandates that “pre-defined” routines will perform all of the SQL operations against the database; the application user simply invokes the stored procedures of functions to perform activities in the database.
2.     There is a component of the scripting application that facilitates the creation of reports. In our application, we are using Actuate’s e.Spreadsheet Engine to create the report and format the report based on a template. The template is provided as input, as well as other data items, into Actuate for processing. The net result is the report is created by the Actuate e.Spreadsheet engine in pdf format and then sent back to the user for distribution to other users in the company.
3.     The Actuate e.Spreadsheet engine consists of one or more JAR files within the Application Server framework. The Web UI utilizes these JAR files as well to perform report generation and data manipulation activities. In the case of the reporting functionality, the pdf report that is generated by Actuate is returned into either the Web UI or into the scripting component for persistence in the database. The mechanism exists to create multi-step jobs that can create multiple reports in one run.
4.     So to facilitate the above, we are creating one or more Java Stored Procedures that will mediate the communication between the PL/SQL the user’s create and the Java components that are required for business processing. PL/SQL will invoke one or more Java Stored Procedures. Then the Java Stored Procedures invoke Actuate e.Spreadsheet, generate the report, saves the report in the database and returns control back to the invoking procedure.
So the question is: Is this a viable and correct use of Oracle Java Stored Procedures. What are the advantages/disadvantages of doing so? Any security issues or potholes that you can think of? Tuning issues for the JVMs? Any white papers that you can think of?
For any Oracle employees that respond, material such as Oracle Whitepapers, etc. would be great.
I can be contacted at (313) 227-4350 or at [email protected]
Thanks in advance.

So are you planning on loading the entire e.Spreadsheet engine into the database server's JVM?
If so, I would expect that to work, but I expect that you'd have some performance issues. I'd expect that the process of building these PDFs is going to be relatively expensive. Tuning the database server's JVM tends to be rather more challenging than tuning JVM's in an app server.
If not, I'm not sure how the Java stored procedure would invoke the e.Spreadsheet engine on the application server. It is possible to use Oracle AQ to send a JMS message, but I don't think you can use the standard J2EE JMS APIs-- I think you'd have to use Oracle's AQ interface.

Using Directory alias in Java stored procedure

hi !!
I want use Directory alias in Java strored procedure
I 'hv created dir alias as
Create Directory BFILE_DIR AS 'C:\MyImages'
my java statements -
myfile="C:\MyImages\myPH01.jpg"
File binaryFile = new File(myFile);
instead of giving absolute path I want give directory alias BFILE_DIR
myfile= BFILE_DIR + "myPH01.jpg"
can anyone pl suugest how should I write this in Java procedure
thanks

Hi there i am currently trying to develope a java
stored procedure and place it in oracle and will try
to use that procedure to send a message to a server
but then it doesnt seems to work. is it possible?And what do you do with exceptions in your java proc?
I haven't ever done it myself, but I would be very surprised if it wasn't possible. I also wouldn't be surprised to find out that you have to configure various things to allow it in Oracle itself.
