SSH integration exception solution reference

(In my recent project, I had a hard time reporting errors, so I went online and shared my mistakes with you)

1.
Org. hibernate. Id. identifiergenerationexception: IDs for this class must be manually assigned before calling save ():
Cause: the <ID> element configuration is incorrect. The <ID> element lacks the configuration of its child element <generator> </generator>. Solution: The <ID> element maps the primary key field of the corresponding database table, and <generator class = "">, the value of class can be increment, identity, sequence, Hilo, native ...... generally, the value is native.
2.
Java. Lang. illegalargumentexception: ID to load is required for loading
Solution: users user = (users) This. gethibernatetemplate (). Get (users. Class, ID); this method cannot be used if the user name is used as a parameter.
3.
Org. springframework. Dao. invaliddataaccessresourceusageexception: cocould not execute query; Nested exception is org. hibernate. Exception. sqlgrammarexception: cocould not execute Query
Solution: SQL statement errors
4.
Severe: Error starting static Resources
Java. Lang. illegalargumentexception: document base d:/program files/Apache Software Foundation/tomcat 5.0/webapps/tomcat-docs does not exist or is not a readable directory
Severe: Error in resourcestart ()

Severe: Error getconfigured
23:32:25 org. Apache. Catalina. Core. standardcontext start
Severe: context startup failed due to previous errors
23:32:25 org. Apache. Catalina. Core. standardcontext start
Severe: exception during cleanup after start failed
Lifecycleexception: Container standardcontext [/tomcat-docs] has not been started
5. JSF + spring + hibernate
Severe: exception sending context initialized event to listener instance of class org. springframework. Web. Context. contextloaderlistener
Org. springframework. beans. factory. beancreationexception: Error creating bean with name 'datasource 'defined in servletcontext resource [/WEB-INF/applicationcontext. XML]: instantiation of bean failed; Nested exception is Java. lang. noclassdeffounderror: ORG/Apache/commons/pool/impl/genericobjectpool
Caused by: Java. Lang. noclassdeffounderror: ORG/Apache/commons/pool/impl/genericobjectpool
Severe: Error listenerstart

Severe: context [/shj01] startup failed due to previous errors
2007-6-8 10:31:55 org. Apache. Catalina. Core. applicationcontext log
Scheme: commons-collections.jar commons-dbcp.jar commons-pool.jar under spring-framework-2.0.5/lib/Jakarta-commons loaded to the Project
6.
Severe: exception sending context initialized event to listener instance of class com. Sun. Faces. config. configurelistener
Javax. faces. facesexception: Can't parse configuration file: jar: file:/E: /tools/Apache-Tomcat-6.0.9/Apache-Tomcat-6.0.9/webapps/jsf02/WEB-INF/lib/jsf-impl.jar! /COM/sun/ faces/standard-html-renderkit.xml
Solution: change the location of the tomcat installation file.
7. Spring MVC + hibernate
Severe: standardwrapper. throwable
Org. springframework. beans. factory. beancreationexception: Error creating bean with name 'sessionfactory 'defined in servletcontext resource [/WEB-INF/applicationcontext. XML]: Invocation of init method failed; Nested exception is Java. lang. nosuchmethoderror: Org. objectweb. ASM. classvisitor. visit (iiljava/lang/string; ljava/lang/string; [ljava/lang/string;) V
Caused by: Java. lang. nosuchmethoderror: Org. objectweb. ASM. classvisitor. visit (iiljava/lang/string; ljava/lang/string; [ljava/lang/string;) V
Solution:
These libraries are used in Spring AOP programming:
Asm-2.2.2.jar
Asm-commons-2.2.2.jar
Asm-util-2.2.2.jar
If hibernate uses Lib:
ASM. Jar
Asm-attrs.jar
The asm-2.2.2.jar and ASM. jar have a class conflict !!!
If either of them is used, the following error may occur:
Java. Lang. noclassdeffounderror: ORG/objectweb/ASM/codevisitor
Java. Lang. noclassdeffounderror: ORG/objectweb/ASM/commons/emptyvisitor
Java. Lang. nosuchmethoderror: org. objectweb. ASM. classvisitor. visit ......
Solution:
1. Remove the three lib related to hibernate from the class path.
ASM. Jar
Asm-attrs.jar
Cglib-2.1.3.jar
2. Add the following four libraries in spring
Asm-2.2.2.jar
Asm-commons-2.2.2.jar
Asm-util-2.2.2.jar
Cglib-nodep-2.1_3.jar
8. Spring MVC + hibernate

Caused by: Java. Lang. noclassdeffounderror: ORG/springframework/AOP/framework/abstractsingletonproxyfactorybean
Solution: without spring 2.0 AOP Libraries

Org. Apache. Jasper. jasperexception: Unable to compile class for JSP:
Solution: the Java code in the JSP webpage is faulty.

The controller does not inherit the multiactioncontroller.

Cause:
When defining turdifficultdao, I wrote an error with a letter and found the error. It was changed, but I didn't change the corresponding one in the get () Set () method.

15.

Java. SQL. sqlexception: Field 'userid' doesn' t have a default value
Cause: Change the primary key of the configuration file to <generator class = "assigned"/> to customize the primary key value, because I did not set the primary key to automatically increase, the default value is affected by <generator class = "native"/> in the configuration file.

16.org. Apache. Jasper. jasperexception: Unable to compile class for JSP

Cause: Java code parentheses on the JSP page are asymmetrical!

 

 

 

17. Error creating bean with name 'sessionfactory'

User reply: Error creating bean with name 'sessionfactory'
User reply: the Java Bean 'userdao 'has a problem,

Cause: severe: Action: NULL
Try again. It may be that the rules of JavaBean are not met.

User reply: Spring configuration file error ~~
User reply: userdao is automatically generated, and spring configuration is certainly OK.
User reply: I have encountered exactly the same problem as you have encountered, and I have not solved it yet. If you have solved it, please let me know. Thank you very much.
Reply: RP
User reply: Reading the error message seems that the setter method in Java Bean is incorrect. We recommend that you check.
User reply: caused by: Java. Lang. noclassdeffounderror: ORG/Apache/commons/pool/impl/genericobjectpool
Some packages are not loaded.
Eclipse is loaded as a data dictionary and needs to be referenced again in Tomcat.
User reply: I wrote about the same issue as you. Now my problem has been solved, and I modified it in the service class, is my service generated using tools? My error is that the Service inherits the hibernatedaosupport class, which is rough

Heart-caused
User reply: I also encountered this error, but I finally found the answer online. You have not imported this package. <bean id = "datasource" class = "org. apache. commons. DBCP. basicdatasource "Destroy-method =

"Close"> in addition to the need for commons-dbcp-1.2-1.jar but also need to commons-pool.jar this package, the next commons-pool.jar package imported into it should be OK, my is solved in this way
