Step
1: Generate or Obtain the Web Service
WSDL

To generate the WSDL file for your organization:
  • Log in to your Enterprise,
    Unlimited, or Developer Edition Salesforce account. You must log in as an
    administrator or as a user who has the “Modify All Data” permission.
  • Click Your Name > Setup > Develop > API to display the
    WSDL download page.

 
  • Click Generate Enterprise
    WSDL.
 
  • Salesforce prompts you to select the version of each installed
    package to include in the generated WSDL.
  • Click Generate.
  • In the right-click menu, Internet Explorer users can choose Save
    Target As, while Mozilla Firefox users can choose Save Link As.

 
Step 2: Download wsc.jar 
Download wsc.jar from http://code.google.com/p/sfdc-wsc/downloads/list 

Step
3: Move all the required files into bin folder 
Move wsc.jar and enterprise.wsdl.xml into
C:Program FilesJavajdk1.6.0_12bin. 

Step
4: Generate enterprise.jar


Syntax: 
java
–classpath pathToJAR/wsc-20.jar com.sforce.ws.tools.wsdlc pathToWsdl/WsdlFilename
pathToJar/JarFilename 

Sample: 
Java –classpath wsc.jar com.sforce.ws.tools.wsdlc
enterprise.wsdl.xml enterprise.jar
This
command will generate enterprise.jar in the same directory C:Program
FilesJavajdk1.6.0_12bin. After these files are compiled, they can be
included in your Java programs for use in creating client applications.

Below is the successful execution of the command.


Note: Never copy the sample syntax and paste it in your Command Prompt.

Step
5: Create a Project in Eclipse

1. Create a Project ‘API’ using Eclipse 
 

 

2. Click Finish.
3. Right click the API Project and create new
Package wsc.

4. Click Finish.
6. Add all the required Jars (wsc.jar,
enterprise.jar)
7. To add the Jars, Right Click Project API, Select
Build Path and then select Configure Build Path.

 
Browse and select the jars to include.
8. Add enterprise.wsdl.xml file.
To add enterprise.wsdl.xml file, copy the
enterprise.wsdl.xml file and Right click API Project and Paste it.

9. Check proxy settings in Eclipse

    • Hi Ajay Kumar,
      You don't have permission to create any file into C-Drive so, just create "Enterprise.jar" in any other directory and the copy it into 'jdk->Bin'.

      Example-

      C:Program FilesJavajdk1.6.0_45bin>java -classpath wsc-23.jar com.sforce.ws.tools.wsdlc enterprise.wsdl "D:enterprise.jar"

  • Hi ,

    I want to use bulk inserting records fron csv file (70,000 reocrds approx.) from external app(java). I have checked you examples from calling from java to salsforce. But how to call this java class from salesforce with csv file data which the user uploading in salesforce?

    Any ideas here will help me a lot.

    Regards,
    Kumaresan M

  • Am i need to use REST API in salesforce with csv file data in body of the call. If yes, then for example in my java rest class, if i call the class (which will insert 70k records) will it be same transaction. (whether Time out limits are there or not) ? What is the way around here ?

    Regards,
    Kumaresan M

  • I am facing issues with sales force heap size limit and other limits while processing bulk records from csv. Thats why we are planning to use java here ? Is it correct approach?

    Regards,
    Kumaresan M
