in the wildfly server i deployed the business-central.war file i got this an above error.

give a solution for above error.

To resolve the "Java heap space" error when deploying the business-central.war file in WildFly, you need to increase the Java heap memory allocated to the server. Here are the steps:

1. Open the standalone.conf (or domain.xml for a managed domain) file located in the WILDFLY_HOME/bin directory.

2. Locate the line starting with `JAVA_OPTS` and modify the `-Xms` and `-Xmx` values to increase the minimum and maximum heap size respectively. For example:

```
JAVA_OPTS="-Xms2048m -Xmx4096m -XX:MetaspaceSize=256M -XX:MaxMetaspaceSize=512m ..."
```

This sets the initial heap size to 2GB and the maximum heap size to 4GB. Adjust these values based on your system's available memory and the application's requirements.

3. Save the changes to the configuration file.

4. Restart the WildFly server for the changes to take effect.

The "Java heap space" error typically occurs when the application requires more memory than what is currently allocated to the Java Virtual Machine (JVM). By increasing the heap size, you provide more memory for the application to run without running out of space.[1][2]

If the issue persists after increasing the heap size, you may need to investigate for potential memory leaks or inefficient memory usage in the application code or its dependencies.[3] Tools like Eclipse Memory Analyzer Tool (MAT) or Java Flight Recorder can help identify the root cause of excessive memory consumption.
