Kettle Flash Back Error:The graphical interface cannot be opened. There is an ETI installation problem

1. Install JDK (version 1.6 or above)

2. JDK environment variable configuration is shown in the figure (the following values are their own installation directory):

3. For the first error, directly flash back, find the spoon.bat in the data integration directory, right-click Notepad to edit, and find the following code to modify

if "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe
if not "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=javaw.exe

change to 

 if "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe
if not "%SPOON_CONSOLE%"=="1" set PENTAHO_JAVA=java.exe

4. If you change the first error and then flash back (modify the memory configuration in spoon.bat)


 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms1024m" "-Xmx2048m" "-XX:MaxPermSize=256m"

change to

 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms512m" "-Xmx1024m" "-XX:MaxPermSize=256m"

5. If the above errors are corrected, the following occurs:

You need to modify the variable value in spoon.bat

pushd "%JAVA_HOME%\jre\bin"
if exist java.exe goto USEJAVAFROMPATH
goto USEJAVAFROMPATH
:USEJAVAFROMPENTAHOJAVAHOME
FOR /F %%a IN ('.\java.exe -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:USEJAVAFROMPATH
FOR /F %%a IN ('java -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:CHECK32VS64BITJAVA
IF %IS64BITJAVA% == 1 GOTO :USE64

add a line:（set IS64BITJAVA=1，make them all TRUE）

pushd "%JAVA_HOME%\jre\bin"
if exist java.exe goto USEJAVAFROMPATH
goto USEJAVAFROMPATH
:USEJAVAFROMPENTAHOJAVAHOME
FOR /F %%a IN ('.\java.exe -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:USEJAVAFROMPATH
FOR /F %%a IN ('java -version 2^>^&1^|%windir%\system32\find /C "64-Bit"') DO (SET /a IS64BITJAVA=%%a)
GOTO CHECK32VS64BITJAVA
:CHECK32VS64BITJAVA
set IS64BITJAVA=1

IF %IS64BITJAVA% == 1 GOTO :USE64

7. After the modification is successful, the graphical interface can be opened after saving

About the error of base64decoder reference in eclipse

Problems encountered:

        Pull Maven project from Git   The base64decoder import file appears   But it keeps reporting errors

Solution:

        After searching for a long time, the solution is probably

                1. Right click the project, build path – & gt; Config Build Path

                2. Select JRE system library to expand and select access rules: no rules define  

                 

                3. Click edit on the right  

                4. Click Add

                5. Modify as shown in the figure

                7. Right click item – & gt; MAVEN —> Update project…..

                Remember to add this item

                

        

If there are any questions     Take a look at the JDK version   A search found an article saying  

OK. My problem is solved~

[Solved] Communications–8–Generated resource conflict: two resources of the same name: /Radioxx

  1. Ecplise: Right-click project -> Properties -> C\C++ Build -> Tool Chain Editor.
    Current Builder: choose  ‘Gnu make builder’ -> Apply (or Ok).

    The reason for the problem: the builder that does not support GCC and G++ compilers is selected. ‘CDT internal builder’

Lamdba in the studio part reports an error. Observe lamdba reports an error but can run

Question:

Ordinary lamdba can be used, such as view. Setonclicklistener {}

Some lamdbas are popular but can run, such as livedata. Observe() {}

solve:

It’s not because the Java version is backward. I updated the kotlin plug-in to solve this problem

Studio even pops up a warning pop-up window of “plug-in needs to be updated” in the lower right corner, but I ignore it everyday… Try to update the Java version and still can’t solve it before you notice it

An error occurred when starting Tomcat in Eclipse: the sub container failed to start

Recently, I used Tomcat in learning java web. Several projects have been created in the early stage, and Tomcat runs normally. Recently, I felt that there were too many projects, which was a hindrance, so I deleted them from the current workspace. Re create a new project. It is found that Tomcat startup fails with an error:

         Critical: the required service components failed to start, so Tomcat cannot be started
         Org.apache.catalina.lifecycleexception: sub container startup failed

  There is a conf configuration folder under the Tomcat installation directory. Open server.xml and there will be & lt; context …….>

  Each time a new project is added to tomcat, an & lt; context ……>, Just delete all the previous ones.

Only delete the context tag, don’t delete & lt/ Host>
