Troubleshooting
You setup webcharts and try to run your page, or the sample page,
but the image is not displayed. What is wrong?
The most common reason is that getImage.jsp file is missing or mislocated. To troubleshoot this issue:
The image is displayed, but instead of showing the chart it shows "Image Expired" message. What is it?
The scripts generated by the designer use indirect method for image retrieval, meaning that the image is produced during page processing and is placed in cache to be retrieved by the browser. After some period of time depending upon cache settings the image is destroyed. "Image Expired" message tells you that the image requested by the browser is not in the server cache. To fix this issue you might want to change cache settings. In some cases the reason is that you used one component to create the image, but another component is used to retrieve it. This is the reason we do not recommend to create MxServerComponent directly, but rather to use getDefaultInstance method that creates a singleton.
