Hi there,
I understand that you are facing an issue with the text expression not displaying correctly when called from JSP in iReport 3.7.3.
To troubleshoot this issue, you can try the following:
Ensure that the JSP page is correctly configured to use the iReport library and that the necessary JAR files are included in the classpath.
Check the HTML code generated by iReport to see if the CSS styles are being applied correctly. You can do this by inspecting the HTML code in a browser.
Try using a different text expression to see if the issue persists.
Update to the latest version of iReport to see if the issue has been resolved.
