[Solved] Troubleshooting of server window error caused by abnormal closing of MyEclipse

Problem description

MyEclipse during the running service because of exceptions to close or directly close the IDE will occasionally lead to server errors

This kind of server error is usually led by a null pointer exception prompting a large chain of exceptions, all due to the error file generated by the exception closure

Solution:

Method 1

You can delete the. Metadata file directly, and it will be automatically regenerated after restarting MyEclipse

Method 2

Delete the following file under MyEclipse and restart to solve the problem

.metadata.plugins\org.eclipse.core.runtime.settings

Error reporting when importing Maven project from MyEclipse

1. Right click the project and build path to see if there is a jar error. Remove useless jars and modify the corresponding JDK version

2. Check the SRC source file to see if there is an error in the source file. Found out, really

On the imported package, an error is reported: the import javax.servlet.annotation cannot be resolved  

Then report in problems: eclipse “cannot be resolved to a type” error

— solution:

Finally, in the process of trying, it is found that the version of Tomcat configured by JDK and eclipse does not match. The JDK version is 1.7   Tomcat is 1.6, so some packages don’t

Solution: build path – add library – MyEclipse server Library (some are server runtime, as long as it can be configured to the server, you can try it with the word server)

Then click. Then in

Click the Tomcat version you installed, and then click OK to finish. The mistake disappeared

MyEclipse startup error: ‘building workspace’ has been accounted for a problem solution

Every time MyEclipse workspace reports an error as follows:’Building workspace’ has encountered a problem. Errors occurred during the build. And the detailed information is: Errors occurred during the build.
Errors running builder’DeploymentBuilder’ on project’bos’.
java.lang. NullPointerException means that a null pointer appeared when deploying the XXX project.

      The picture is as follows:

I used to rebuild the workspace, but in this way all the settings have to be re-imported. The existing method is unsatisfactory: go to the folder where the workspace is located: E:\Workspaces\MyEclipse 10\.metadata\.plugins\org Delete the file com.genuitec.eclipse.ast.deploy.core.prefs under .eclipse.core.runtime\.settings\

Note:

1. The green part of the above path may be different from the personal workspace directory and Myeclipes version, please find your own workspace directory.

2. You must exit the myEclipse tool before deleting it

 

MyEclipse open JSP report unhandled event loop exception no more handles error

When using MyEclipse, an unhandled event loop exception no more handles error pops up. Click OK, and then close the workspace. After restarting the workspace, as soon as you click the JSP file, the error will pop up

Search for answers on the Internet and say to change the default JSP editing tool. The method is as follows:

windows -> preferences -> General -> Editors -> File associations to change the default editing tool for *. JSP files

This method has been tried, but it still has no effect

Continuing to search for answers, I found that I wanted to change/delete the workbench.xml file in the workspace. I tried to delete several newly added JSP/JS files in the workspace. After restarting, the problem remained the same. Later, I directly deleted the file. After restarting, I would not report the error. Deleting the file did not cause any negative impact

Workbench.xml file location: e::?MyEclipse_ workspace\.metadata\.plugins\org.eclipse.ui.workbench

Find MyEclipse workspace and delete it
