[Solved] Weblogic error: java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11G

Error message: Java.lang.NoClassDefFoundError: Could not initialize class sun.awt.X11G

After looking at the background, locate the error code as follows

//Save a thumbnail image locally
BufferedImagesrc=ImageIO.read(file2);
FilelocalDir=newFile(GlobalConstants.SAVE_PATH+GlobalConstants.SMALL_IMAGE_SAVE_PATH);
if(!localDir.exists()){
    localDir.mkdirs();
}
//The following code starts reporting errors
BufferedImageoutImg=newBufferedImage(60,60,BufferedImage.TYPE_INT_RGB);
outImg.getGraphics().drawImage(src,0,0,60,60,null);

Solution:

Open the setDomainEnv.sh configuration file under the weblogic domain service bin

Add parameters in the following positions:

JAVA_OPTIONS="${JAVA_OPTIONS} -Djava.awt.headless=true " ​
export JAVA_OPTIONS

The WebLogic Server cannot open the print window in the program

After the program is deployed, the program has the print function, but the print window cannot be opened when clicking the print function. Solution:

Error reported: caused by: java.lang.noclassdeffounderror: could not initialize class sun.awt.x11graphicsenvironment

Solution: enter Weblogic Directory:/home/Weblogic/APP/Oracle/Middleware/user_ projects/domains/base_ domain/bin/

Modify the setdomainenv.sh file:

add to:

JAVA_ OPTIONS=”${JAVA_OPTIONS} -Djava.awt.headless=true”

export JAVA_ OPTIONS

Just restart the service

Unrecognized option of Weblogic startup error: – JRockit

Does anyone know what is going on with this?

The jar package loaded at WebLogic startup is as follows.

The operating system is Windows, using the Windows service method to start

Solution:

1, check whether the jar package is normal, has not been damaged?

If the jar package is corrupted, weblogic can’t read the contents of the jar package, so decompress the jar package and then compress it to solve the problem.

2, see the weblogic startup jdk and the project compiled jdk is not unified?

It is said that this is because the loaded package is not recognized by jvm. For example, if you develop with IBM’s JDK, you deploy with sun jdk compiled package will appear this situation

3, to see if the project jar and weblogic comes with the jar package has a conflict

There is a saying that weblogic may come with some jar, the project also has some jar package, the version of these jar packages may not be consistent, such as the project than the weblogic version is higher, generally on the weblogic will only load a jar, regardless of the version, so the priority load the project jar

[cause analysis]:

1. Thread execution time is too long, blocking problem occurs, analyze the log to view the thread class name of the problem.

2. The execution time of SQL statement is too long.

 

[solution]:

It can be solved by the following methods:
1) modify the stuckthreadmaxtime parameter, change the default 600s to 1200s, or other suitable values.
2) Increase the number of threads to prevent thread blocking.
3) Optimize the program and reduce the processing time.

 

Optimize the SQL statement:
1) optimize the info_ Sign, PPMC and other fields to establish a standard table, query from the database, try to reduce the use of in
2) do not use & lt; &> operators, use &> or & lt; instead
3) try to reduce the use of sorting order by, rownum, only in the critical moment, other time can not use it.
