JDBC :: Uploading Template File Into Database Using SetBlob Or SetBinaryStream
Jun 1, 2015
I have a template file which I'm tring to upload into a database using setBlob or setBinaryStream but I'm getting the following error:
java.lang.AbstractMethodError: setBlob
at weblogic.jdbc.wrapper.PreparedStatement.setBlob(PreparedStatement.java:1005)
at com.capitalone.citrix.ssp.dao.KatetDaoImpl.uploadReport(KatetDaoImpl.java:1697)

at com.capitalone.citrix.ssp.controller.JSONController.display(JSONController.java:61)

[Code] .....
I'm using :
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production
Weblogic Server Versions: 10.3.0.0 with Java 1.6.0_05
The driver class name for the weblogic datasource: weblogic.jdbcx.oracle.OracleDataSource
Initially, I tried:
sqlQuery = new StringBuffer();
ps = null;
sqlQuery.append("insert into KATET_REPORTS (FILE_DATA)");
[Code] ....
This failed, so I changed ps.setBlob(1,is)
to
ps.setBinaryStream(1,is). This failed as well with teh same error, just for setBinaryStream instead of setBlob.
Is there a known inconsistency between that driver and this Weblogic version? Is there something else going on? If I haven't given enough data to debug the issue here, what other data should I gather?
I'm learning jQuery to integrate into a JSF application but finding some confusion on the correct syntax especially when it comes to combining double and single quotes in the jQuery scripts. So for this particular page I want jQuery to traverse through a list of documents and put icons next to each document to state what type of document each is (ie: PDF, doc, xls). I can get this to work using normal html markup but I get a Syntax Error - Unexpected Token exception in the browser.
I'm confused about whether this means I need to use the right html references for the JSF element I wish to traverse or whether this is a problem with the way I'm using my quotes.
Also I'm not sure how to correctly reference jsf tags inside jQuery scripts. So for an ordinary html page I execute the following jQuery script:
I want to create a simple ftp server which can upload and download a single file. i found code from google search but its showing error : connection refused . here is my server code n client code.

I created a database in mysql, but I have problems communicating with the DB in java.
Here is the error :
java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/books at java.sql.DriverManager.getConnection(DriverManager.java:604) at java.sql.DriverManager.getConnection(DriverManager.java:221) at displayauthors.DisplayAuthors.main(DisplayAuthors.java:30) java.lang.NullPointerException
[Code] ....
HERE IS THE CODE
public class DisplayAuthors { // database URL static final String DATABASE_URL = "jdbc:mysql://localhost:3306/books"; // launch the application public static void main( String args[] )
This question is not about syntax but a best way to handle something. What is the best way to store a image into a database? For example converting it into binary etc. I just wanted to get some opinions.
This the output of java from my PC under linux platform (rhel 6.5).

I have completed an assignment for my university in which I had to make a Java NetBeans project. My project is now completed but now I have to make a setup of my NetBeans project and give the university the setup file, only.
My question is, the software I made has a database attached to it, meaning the purpose of the software is to be used with the database. Values must be saved in the database, deleted from the database etc.. I have used MySQL database connections with the JDBC driver
I have used exe4j to make the .exe file and Setup Factory to make the exe file and setup file respectively. Once I make the setup and run the setup, the application works, ON MY COMPUTER. The computer which made the software. But once I take it to a computer in which MySQL was not installed, the setup installed, but the software did not work.
I have small Java code, which execute every day and checks for data in database using Cronj Schedular and everything works fine, but recently I have observed that, it is failing due to
java.sql.SQLException: No suitable driver found for jdbc:oracle:thin:@160.110.xx.xxx:1521/test
At the same time, when I run my test code to check Database connectivity that works fine without above exception. I'm unable to figure it out. Although, there was just slight code change, but that was nowhere related to Database or Database connection.
dbconf.java public class dbconf { private Connection connect; private String connstr; public Connection getConnection() throws SQLException { connstr = "jdbc:oracle:thin:@160.110.xx.xxx:1521/test";

So, you can see, It failed on 3rd of July and 5th July as well. But, in between it ran fine.
I am trying to run a simple program that connects to a mysql database and prints out some fields. I am using Eclipse.
THe problem I am having is on the following line of code.

I have done some research and from what I have found is that I need to alter the class path to pick up the driver. When I downloaded the .msi I ran it and then the program closed. Where the files are ??? How to locate and import the file so I need to get my program to run?
I have included all the of the source code below.
package mySQLConnect; import java.sql.*; public class Connect { // JDBC Driver name and database URL static final String JDBC_DRIVER = "com.mysql.jdbc.Driver"; static final String BD_URL = "jdbc:mysql://localhost/sstbde";
We currently have an application which uses JDBC to connect to the backend database (DB version - 11.2.0.3 ). The application uses a properties file in which the password for the db schema is hardcoded in plain text format. Due to security restrictions we have been asked to make sure the password is encrypted in the file and no direct access is made to the schema using the plain text password. Best options we can use to make this password encrypted both at Oracle DB side and Java side.
calling a parameterized stored procedure in java jdbc from sql server.The stored procedure goes like this in sql

I am new to Java, programming, and intelliJ. I am trying to make a BMI Calculator using this code as my initial template which converts Fahrenheit to Celsius.
import javax.swing.JFrame; public class Fahrenheit { //----------------------------------------------------------------- // Creates and displays the temperature converter GUI. //-----------------------------------------------------------------
[code]....
I created a local field within BMIButtonListener for weight, height, resultLabel, and was able to compile but it did not calculate and listed exceptions.
If I have a web page with a lot of data to show, say a lot of tables and graphics, would using non JSP based frameworks result in a lot more individual AJAX requests? For example if the page have 5 tables, with JSP the whole page will be returned to the browser with data for all 5 tables already. But if this is a pure HTML / Javascript based view, then we need to have each of the 5 tables to make individual AJAX requests in order to render the page. Is this indeed the down side for not using JSP?
The reason I'm asking is because I'm considering moving away from JSP to a template based framework such as Thymeleaf or Freemarker.
I would like to know what is the best way to upload & download files using Servlets/Jsp's . In some websites I have seen example using third party API(by oreilly). Is it better to follow any third party or can we do it just by using I/O streams. What are the steps of uploading files. And where do we need to store files once the user uploads ,Database or server??
i have a service to save some form fields from the client and i need to add uploading image to that service using json. the service consumes json and produces json.
I am developing an inhouse project in my organization. I unable to implement the pdf uploading, downloading, report generation logic as i am totally new to this implementation.

I am learning how to program in JAVA servlet+MySQL. Decided to make a simple program where it shows who is celebrating birthday today by retrieving data from database. At the moment I managed to get it working by loading a form.html and pressing the button in it which gets to the result.jsp and shows results there.
My plan was to get a list of people who are celebrating there birthdays initially when the website is loaded/being loaded, I mean when you enter URL into your web browser and you get it instantly in browser. Is there a way to do it the way I want (JAVA+servlet+MySQL) instead of pressing a button/link?
I am looking for java codes to generate a word document based on a word template, basically, I have a word template created and in my local path, the template has a proper format with some fields which will be filled in after java codes ran. The java codes will fetch one record from a table, and open the word template and then fill the fields in the word template, and created a new word document and save it in another folder.
I found this example: [URL] which is similar except it uses xml template instead of word template, how to make it work to change the template from xml to word (docx) template?
