OS: Windows 7 SP1
Server: Tomcat 6
JRE: 1.7
MyEclipse Enterprise Workbench
Version: 2015 CI
Build id: 13.0.0-20141111
Run in debug mode

This issue has been there for a long time, I am not clear if the issue is ide specific though. When the server is launched and running in the debug mode, edit the java source file (e.g: hello.java) and save it. Then open a web page (e.g: main.jsp or other jsp pages), this error will appear as shown below. It is confusing that the main.jsp will be affected (recompiled in debug mode) if the hello.java is modified, which seems not relevant at all. Although this problem can been dealt with by restarting the server every time the error occurs, the repetitive work has been intolerable since I need to edit source files and review the effect in debug mode. So, I am looking for a solution here and your answer would be appreciated!

Lewis,

Sorry that you are seeing this issue. I could not replicate the issue at my end.

1.Can you please update to the latest release, CI 13 and check if the issue persists? Please go to Help > Check for Updates and update to CI 13.If possible, switch to a new workspace and check.

2. Can you please clarify if you are seeing this issue with only a particular project? You can install a simple web project from our Examples On-Demand (MyEclipse > Examples On-Demand > ‘Hello World’ Web Application ) and check if the hot deployment works.

3. To rule out issues with Tomcat 6.x, can you please deploy the project to MyEclipse Tomcat 7.0 and see how it works?

4. If the issue persists with MyEclipse Tomcat 7.0 as well, then please send us the project along with what exact changes you are making to the java file to help us investigate further. Also send us the .log file which is located at workspace dir/.metadata/.log. Before sending the .log,please delete the contents of the file and replicate the issue with hot deploy.

Let us know how it works for you.
