From a third-party application

On many occasions, the external library functionality is embedded in a third-party application along with the esProc application. In this case, you need to manually write the following code in the <Runtime><EsProc> ... </EsProc></Runtime> in raqsoftConfig.xml file.

<extLibsPath>directory of external library folder </extLibsPath>


<lib> external library folder name </lib>


The following introduces how to deploy and connect an external library from a third-party application, by taking the case of embedding esProc into a Java application as an example:


1. Load the necessary jars

For this you can refer to the section Deploying JDBC in Tutorial. Besides the necessary esProc jars, the corresponding Raqsoft core external library jar and the related third-party jars should also be in place under the targeted directory. The Raqsoft core jar and the third-party jars an external library requires are listed in Deployment.


2. Configure raqsoftConfig.xml file

Refer to section Configuring raqsoftConfig.xml in Tutorial to configure the external library node <lib>.

To access WebserviceCli, for instance, the core jar is under C:\Program Files\raqsoft\esProc\extlib\ WebserviceCli, and the configuration is like this:

<extLibsPath>C:\Program Files\raqsoft\esProc\extlib</extLibsPath>





To access multiple external libraries, the configuration is like this:






3. The dfx file for deploying and accessing the WebserviceCli external library:






Access the weather forecast server



Access the domestic flights schedule server


Refer to section Integration & Application – Java Invocation in Tutorial for the deployment of the dfx file.

Now, you can call the dfx file from a Java application.
