Tomcat an error has occurred. See error log for more details. 80

If none of the following methods works, delete myeclipse and reinstall it. Do not change the installation path this time. The solution is provided as follows: method 1. Go to "start" --> "run" ----> enter "cmd" to enter the command prompt line, and then enter the eclipse installation directory,                Enter eclipse-clean (this method is successfully used)Method 2: delete all files except config. ini in the configuration folder and restart eclipse.


The solution for myeclipse becomes:
Execute myeclipse.exe-clean on the command line to clear the cache.




Other error solutions:

After the execution, the problem is still not solved.


After the attack, it is found that the program fails to execute as long as the Chinese name is entered. However, if the English name is entered, the system will return the license No correctly, during system installation, is this problem because my user name is Chinese and not a user of the system administrator user group?


Delete the directory again, create an English directory under the user directory, grant the full read and write permissions to the current user, and then install the system again, install myeclipse 8.5 In the new directory.


When the system is started, there is a workspaces directory by default, which also points to a directory that does not contain Chinese text. After this startup, no output is reported.

An error has occurred. See error log for more details.107

Error message to solve the problem.

Appendix: myeclipse 8.5 Startup Process Optimization

Myeclipse5.5: 139 m; myeclipse6.5: 451 m; myeclipse7.0: 649 m; myeclipse8.0: 772.3 MB (faster than 7.1 and 7.5, but still very expensive)
The download speed of the server is exhausted because it is abroad, as long as your performance is top-notch. Unfortunately, myeclipse is a master of crazy memory, especially when myeclipse7.0 runs, it basically does not need to do other work. It is a quick update, and a updating indexes, when you wait for the update, the old man will automatically validate it again!

I have collected some methods to solve the memory consumption of myeclipse, which is very effective after testing. I hope it will be convenient for more friends.

1. the quick update error always pops up and the quick update automatic update function of myeclipse is disabled.
The solution to this problem is to disable automatic updates.
Windows> preferences> myeclipse enterprise workbench> community essen,
Remove the prefix of the "search for new features on startup" option.

2. Disable updating indexes
Window> preferences> myeclipse enterprise workbench> maven4myeclipse> Maven>
Disable download repository index updates on startup.

3. Disable automatic validation of myeclipse
There are a bunch of validation items, such as XML, JSP, JSF, and JS. We don't have to verify them all automatically,
Manual verification is only required, and the speed is immediately improved to several levels
Windows> perferences> myeclipse> Validation
Uncheck all build
If you need to verify a file, we can verify it separately. The method is:
On the file to be verified (right-click-> myeclipse-> RUN validation.

4. Start optimization and disable unnecessary modules.
20% of the functions of a system can meet 80% of the requirements, and myeclipse is no exception. We only need 20% of the system functions most of the time,
Therefore, some unused modules cannot be loaded or started.
Window> preferences> General> startup Andy shutdown lists the modules loaded at myeclipse startup.
I only want it to load Tomcat 5 and check myeclipse easie Tomcat 5.
How can we know which startup items are useful? I want to explain the usefulness of the startup items I know,
I hope you can understand the following:
WTP: similar to myeclipse, the main difference is that WTP is free of charge. If myeclipse is used, this can be canceled.
Mylyn: A team task management tool, similar to CVS, which manages the project progress in task units and can be canceled if it is useless.
Derby: a database saved as a jar. It is useless and canceled.
A large batch of startup items prefixed with myeclipse easie: the servers supported by myeclipse are only used by the user, and other items are canceled,
For example, I only select tomcat.

5. Remove the spelling check of myeclipse (if you think it is useful, do not go)
Spelling check may cause us a lot of trouble. Our method names will all be abbreviations of words, and he will prompt that there are errors,
So it is best to remove it, which is of little use.
Window> perferences> General> editors> text editors> spelling> deselect the Enable spell checking check box.

6. Remove the complicated built-in plug-in automatic add-on of myeclipse
Window> perferences> General> startup and shutdown> activated plug-ins on startup
The check box in can be selectively checked and removed.

7. Modify the editing tool when myeclipse edits the JSP page
Window> perferences> General> editors> File Associations>
In file types, select *. jsp> set "myeclipse JSP Editor" to default in associated editors.

8. Modify the eclipse. ini file in the myeclipse installation directory to increase the non-heap memory of JVM.
The details are as follows:
-Clean
-Showsplash
Com. genuitec. myeclipse. Product. ide
-- Launcher. xxmaxpermsize
256 m
-Vmargs
-Xms128m
-Xmx512m
-Duser. language = EN
-XX: permsize = 128 m
-XX: maxpermsize = 256 m
Increase the following-XX: maxpermsize, such as-XX: maxpermsize = 512 m, and then change-XX: permsize
-XX: The size of maxpermsize is the same.
