How to Download and Install sapjco3.jar and sapjco3.dll Files for SAP Java Connector
The SAP Java Connector (SAP JCo) is a development library that enables a Java application to communicate with SAP systems via SAP's RFC protocol. It supports both inbound and outbound RFC communication, as well as various data serialization formats and network protocols. The SAP JCo is available on the SAP Software Downloads Center[^2^].
In this article, we will show you how to download and install the sapjco3.jar and sapjco3.dll files for the SAP JCo 3.1, which is the latest version as of April 2023. These files are required for running SAP-enabled Java applications on Windows operating systems.
Step 1: Download the SAP JCo 3.1 SDK
To download the SAP JCo 3.1 SDK, you need to have a valid SAP user ID and password. You can access the SAP Software Downloads Center at https://launchpad.support.sap.com/#/softwarecenter. Search for "Java connector" and select the 64-bit Java connector for Windows. You can also use this direct link: https://launchpad.support.sap.com/#/softwarecenter/template/products/_APP=00200682500000001943&_EVENT=DISPHIER&HEADER=Y&FUNCTIONBAR=Y&EVENT=TREE&NE=NAVIGATE&ENR=01200314690900003455&V=MAINT&TA=ACTUAL&PAGE=SEARCH/SAP%20JCO%203.1%20SDK%20FOR%20WINDOWS%20X86_64.
The SDK package includes the software, documentation, and examples. The file name is sapjco-ntamd64-3.1.x.zip, where x is the patch level. The current patch level is 7, so the file name is sapjco-ntamd64-3.1.7.zip[^2^].
Step 2: Extract the ZIP File
The ZIP file contains another ZIP file inside it. You need to extract both ZIP files to get the sapjco3.jar and sapjco3.dll files. You can use any ZIP extraction tool, such as WinZip or 7-Zip.
After extracting the files, you will see a folder named sapjco-ntamd64-3.1.x, where x is the patch level. Inside this folder, you will find another folder named jco, which contains the sapjco3.jar file. You will also find a folder named ntamd64, which contains the sapjco3.dll file.
Step 3: Copy the Files to the Appropriate Location
You need to copy the sapjco3.jar and sapjco3.dll files to the lib folder of your Java application server, such as Apache Tomcat or IBM WebSphere. For example, if you are using Apache Tomcat, you can copy the files to C:\Program Files\Apache Software Foundation\Tomcat 9.0\lib.
You also need to add the sapjco3.jar file to your Java classpath, either by using an environment variable or by modifying your application server configuration.
Step 4: Test Your Installation
To test your installation, you can use one of the examples provided in the SDK package. For example, you can use the CheckJCo.java program, which checks if the SAP JCo is installed correctly and displays some information about it.
To run this program, you need to have a valid SAP system connection parameters, such as host name 9160f4acd4
